Reinforcing Bar Binding Machine - Patent 8127803

Patents-433 — Sat, 14 Apr 2012 21:08:37 GMT

shared by: Patents-433 on: Saturday, April 14, 2012

1. Field of the Invention The present invention relates to a reinforcing bar binding machine in which a wire pulled out from a wire reel is fed to a guide part provided on the tip end of a binding machine body, curled by the guide part and fed out to the circumference ofthe reinforcing bars arranged inside the guide part, and looped and wound around the reinforcing bars and twisted to bind the reinforcing bars. 2. Background Art A reinforcing bar binding wire is pulled out from the wire reel, and fed out from a guide part on the binding machine tip end while being curled, and looped and wound around reinforcing bars, and at the guide part, the wire must be curled andfed out. In order to curl the wire, the wire should be bent by at least three points. That is, the guide part includes three components arranged in order, an end portion of a guide tube which guides feeding of the wire from the wire reel, a wire cutting mechanism for cutting the wire after feeding out a predetermined amount ofthe wire, and a curl guide which curves the wire fed from the wire cutting mechanism (refer to JP-B2-3496463). These three components have functions for cutting the wire and guiding the wire, and these are used as said three points for curling the wire. However, the above-described configuration has the following problems. The three components have complicated shapes, and easily vary in dimensions and attaching positions. Therefore, these may pose problems that the curl diameter of the wire fed out from the guide part is excessively small and the hooks cannotgrasp the wire, or the curl diameter is excessively large and the end portion of the wire returned after being looped cannot enter a curl pickup guide of the guide part. Therefore, dimensional control is very troublesome and the component costincreases. Further, the three components which curl the wire are always worn by the iron-made wire, so that they are worn, and in particular, a portion which forms a curl on the wire

Spring And Spring Processing Method - Patent 8069881

Patents-433 — Tue, 13 Dec 2011 10:48:21 GMT

shared by: Patents-433 on: Tuesday, December 13, 2011

BACKGROUND Conventionally processed helical coil springs possess a residual stress distribution that is not ideal for durability. Using known spring-coiling processes, the highly-stressed inner diameter of the resulting spring is placed in a state ofresidual tensile stress after coiling. Even after inducing a layer of residual compressive stress via shot-peening or otherwise, there exists a sub-surface state of residual tensile stress. This residual tensile stress is undesired and leads to excessfatigue and premature spring failure. As such, it is highly desirable to eliminate the residual tensile stress and/or to completely reverse same by imparting residual compressive stress to the spring during its manufacture or by subsequent treatment. Back-bending by forced-arbor coiling is one example of a process used during coiling of the spring to alleviate residual tensile stress at the spring inner diameter. Post-coiling techniques for residual stress enhancement include shot-peening,piece hardening and nitriding. All of these known techniques are associated with undesired consequences such as reduced hardness, increased variation/distortion, extreme brittleness and/or greater risk of introducing defects. The above residual stress enhancement techniques do not yield springs having sufficiently large residual compressive stress, i.e., -40 ksi (1 ksi=1000 lb/in.sup.2) and below, at extended depths, i.e., deeper than 0.008'', moving into the wirefrom which the spring is formed from the inner diameter of the spring toward the outer diameter of the spring. With the advent of improved wire surface quality as well as improved spring manufacturing techniques, one of the most common failure modes of engine valve springs is high cycle fatigue due to the inevitable impurities in the steel. Thesenon-metallic inclusions commonly initiate fatigue cracks after a significant number of cycles, and at a depth below the surface where compressive stress from shot-peening is either l

shared by: Patents-433 on: Wednesday, November 09, 2011

The present invention relates to a metal tie tool, and more particularly to a metal retained tension tie tool with an electric tension control system.BACKGROUND OF THE INVENTION As is well known to those skilled in the art, cable ties, or straps are used to bundle or secure a group of articles such as electrical wires and cables. Cable ties of conventional construction include a cable tie head and an elongated tailextending therefrom. The tail is wrapped around a bundle of articles and thereafter inserted through the passage in the head. The head of the cable tie typically supports a locking element, which extends into the head passage and engages the body ofthe tail to secure the tail to the head. In practice, the installer manually places the tie about the articles to be bundled and inserts the tail through the head passage. At this point, a cable tie installation tool is used to tension the tie to a predetermined tension. The tools ofthe prior art, although capable of tensioning and thereafter severing the excess portion of the cable tie, typically have several disadvantages therewith. As a result, it is desirable to provide a metal tie tool having an improved electric tensioncontrol system. It is also desirable to provide a metal tie tool having an improved ball set and cut-off mechanism.SUMMARY OF THE INVENTION A tool that installs a metal tie is disclosed. The tool includes a tension mechanism that tensions a metal tie around a bundle and a tension control system that measures the applied tie tension. The tension control system includes a load celland a worm cushion that dampens the tension applied to the load cell. The tension mechanism includes a gear train with a worm gear and a worm that distribute the applied tension to the load cell and rotary gripper gears that tension the metal tie. Oncethe load cell measures the desired applied tie tension, the tension mechanism is de-energized and a ball set and cut-off mechanism is activated to set the b

1. Field of the Invention The present invention relates to a reinforcing bar binding machine including a binding device which binds arranged reinforcing bars by twisting a wire looped and wound around the reinforcing bars. 2. Background Art In a reinforcing bar arrangement process of a reinforced concrete construction work, as a tool for binding reinforcing bars at a crossing point, etc., of reinforcing bars, a reinforcing bar binding machine is known. This reinforcing bar bindingmachine is provided with a binding device for binding reinforcing bars. As shown in JP-B2-3496463, this binding device includes a sleeve which is provided inside the binding machine body and has reinforcing bar binding hooks pivotally mounted to the tipend, a tip end shaft which is fitted to the inside of the sleeve and generates a load for advancing and retreating and rotating the sleeve, and engaging means (fins) for controlling the rotation of the sleeve in cooperation with rotation stoppersprovided on the binding machine body, and advances the sleeve by rotating the tip end shaft by a motor, and accordingly, closing and actuating the hooks to make the hooks grasp the reinforcing bar binding wire, and further rotates the hooks together withthe sleeve to twist the wire and bind the reinforcing bars. In the binding mechanism described above, the sleeve has a double structure including an outer sleeve and an inner sleeve, and the front portion of the outer sleeve holds the hooks rotatably and the rear portion of the outer sleeve prevents thekey engaging with a screw groove of the tip end shaft from coming out, and to the front portion of the inner sleeve, a shaft for holding a guide pin for opening and closing the hooks is attached, and the rear portion holds the key in a fitting manner. The outer sleeve and the inner sleeve are actuated integrally, so that for integrating these sleeves, as shown in FIG. 11, a set screw 53 is screwed into the inner sleeve 52 from the outer sleeve 51.

Method And Machine For Binding Elongate Objects Together - Patent 8047239

Patents-433 — Wed, 09 Nov 2011 10:39:23 GMT

shared by: Patents-433 on: Wednesday, November 09, 2011

The present invention relates to a method for binding elongate objects together by means of at least one wire, in particular for lashing reinforcing bars, electric cables or the like, two claws provided with guide surfaces for the wire beingguided down over the objects to be bound together, after which a wire is fed along the guide surface of one claw and across to the guide surface of the other claw, so that it is shaped into a wire loop surrounding the objects on three sides, and the legsof the wire loop are twisted together on the fourth side of these objects. The invention also relates to a machine for use in implementing such a method.BACKGROUND OF THE INVENTION Conventionally, the lashing of reinforcing bars to form reinforcing mats is carried out with the aid of simple, manual tools, which is a very time-consuming and thus expensive and also laborious operation, which is apt to give rise toattritional injuries. The reason for this is that, when lashing reinforcing mats for concrete slabs, arches or the like using previous aids, the operator has to bend for long periods of time, which leads to great stress on the back. In this connection, the lashing of the reinforcing bars is usually effected with the aid of tongs or a twisting tool, by means of which the ends of a wire, which is arranged by hand around the reinforcing bars at the various intersection points,are twined or twisted together for firm connection of the bars. Carrying out lashing in the conventional manner also involves risks of accident, especially in the case of work on roofs, bridges and the like, owing to the stooped working position which,inter alia, leads to risks of falling accidents. In my International patent application PCT/SE91/00571, a machine is described for binding intersecting bars together by means of wires, in particular for lashing reinforcing bars, which machine works in accordance with the method indicated inthe first paragraph above. By means of this machine, the lashing

Wire Curl Diameter Adjusting Mechanism For Tying Machine - Patent 8033303

Patents-433 — Tue, 08 Nov 2011 16:08:25 GMT

shared by: Patents-433 on: Tuesday, November 08, 2011

The present invention relates to a wire curl diameter adjusting mechanism for a tying machine.BACKGROUND ART Generally, in a rebar tying machine, it is important to reduce errors by ensuring a sufficient tying force. Accordingly, a desired curl diameter has to be formed. In order to obtain the desired curl diameter, it is necessary to decrease anon-uniform degree of the curl diameter during a production or to increase a tying width of the curl diameter of the tying machine itself. Various members are used to form the curl diameter, so that it is difficult to form a predetermined curl diameter due to tolerances of the members . In particular, when a diameter of a rebar as an object to be tied is large, it is necessary toincrease the curl diameter. When the curl diameter is large, a problem arises in that a production is difficult because required processing precision becomes very strict. Therefore, it may be supposed that the above-described problem is handled by adjusting the attachment positions of the members used to form the curl diameter. Accordingly, it is possible to form the correct curl diameter by adjusting errorscaused by the tolerances of the members (for instance, see JP-A-07-132914). Incidentally, in members for guiding a wire so as to form a curl diameter, some of the members may tend to clog the wire. Particularly, the wire clogging may easily occur in a front-end guide member which is the most important to form the curldiameter. For instance, when the tying machine is operated in a state where there is a very little remaining amount of the tying wire wound around a wire reel, a feed operation is stopped in a state where the front end of the wire does not protrude fromthe guide member. As a result, a problem arises in that the cut tying wire remains in the tying machine. Since it is not possible to remove the remaining wire to the outside, a user needs to detach the guide member so as to remove the remaining wire. At this time, after the det

Patents-433 — Sun, 02 Oct 2011 10:36:20 GMT

shared by: Patents-433 on: Sunday, October 02, 2011

FIELD OF INVENTION The present invention relates to tools used to form loops in an electrical conductor to prepare the conductor for attachment to a tie-down bolt of an electrical terminal.BACKGROUND OF INVENTION A number of tools have been designed to address the task of shaping the end portion of a conductor so as to provide a loop suitable for attaching the end of the conductor to a tie-down bolt such as those found on electrical outlets, switches,and similar electrical system components. Some examples of such devices are taught in U.S. Pat. Nos. 4,257,159; 5,520,227; and 5,309,954. While some of these tools can provide U-shaped loops, they were not suitable for forming "?"-shaped hooks, which are desirable so as to facilitate positioning of the loop around a shank under a retaining head of a tie-down bolt. One tool whichapparently could be used to form "?"-shaped hooks is commercially available from Klein Tools, Inc., of Lincolnshire, Ill. This tool resembles a conventional screwdriver or nutdriver, but is provided with a post that is offset from and extending parallelto a shank of the driver. A conductor can be placed between this post and the shank and the tool rotated about a longitudinal axis. When so rotated, the post restrains the end of the conductor, causing the conductor to bend about the shank to form aU-shaped loop. The direction of rotation can then be reversed, which brings a standing portion of the conductor against the post to allow the user to create a reverse bend to change the U-shaped loop into a "?"-shaped hook.SUMMARY OF INVENTION The present invention provides a tool for an electrician that can be configured to preform various functions associated with the wiring switches. Depending on the details of the configuration the tool, it can be tailored to provide a consistentsize and configuration of a loop or hook and/or to tuck a loop under a retaining head of a tie-down bolt. The tool can be configured to provide a bending cradle to

Patents-433 — Tue, 21 Jun 2011 10:54:36 GMT

shared by: Patents-433 on: Tuesday, June 21, 2011

The present invention is directed toward apparatus for twisting wires and, more particularly, toward a pair of pliers that incorporates a power driven chuck for twisting together the ends of a plurality of electrical wires for making anelectrical connection between them. The twisted wire ends are then covered by an insulated wire nut. Electricians, technicians, mechanics, home handymen and numerous others frequently must connect the ends of electrical wires together. Such connections must provide both electrical continuity and be mechanical secure. This is normallyaccomplished by twisting the ends of the wires together. In many cases, it is desirable to secure three or four or more wire ends together. After the wire ends are twisted together, an insulated wire nut or similar device is threaded thereon tomaintain the wire ends in place. If high gauge wires or numerous smaller gauge wires are to be connected together, a substantial force must be applied to effectuate the twist. Usually pliers or the like are utilized to accomplish the twisting. This is done by grasping theseveral wire ends with the pliers and turning the pliers. Obviously, the pliers can be turned only ninety degrees or so before the pliers must be released and the wires gripped again to continue the twisting. This can be time consuming and can putundue force on the electrician's arm. To Applicant's knowledge, there is no tool available to assist in twisting wire ends together. And there certainly is no power tool available for this purpose. Therefore, a need exists for a power operated hand tool that can easily and quicklytwist the ends of electrical wires together.SUMMARY OF THE INVENTION The present invention is designed to overcome the deficiencies of the prior art discussed above. It is an object of the present invention to provide a tool that can easily twist wire ends together. It is another object of the present invention to provide a power tool for connecting wire ends together t

Method, An Implement And A Twister For Tying Together End Portions Of Wire Material Extending Around A Bale - Patent 7690402

Patents-433 — Thu, 28 Apr 2011 16:43:20 GMT

shared by: Patents-433 on: Thursday, April 28, 2011

AND BACKGROUND ARTThe present invention relates to a method, an implement and a twister for tying together end portions of wire material extending around a bale.To facilitate storage, handling and transportation of loose material, such as waste paper and cardboard, waste plastic, straw, it is usual to press the material into bales.To prepare the bales, the material is pressed in a baling press. A baling press typically includes a baling channel in which a pressing ram is reciprocally movable to and fro, new material to be baled being added each time after the press hasbeen retracted. The counter pressure against which the bales are pressed is obtained by resistance encountered by the material as it is pressed through the pressing channel, which, to that end, has a cross-section that decreases in downstream directionover at least a portion of its length. Initial counter pressure may be obtained by mounting obstacles in the pressing channel.For facilitating separation of the pressed material into distinct bales and for keeping the bales together, wire material is usually tied around the bales. The wire material is usually steel wire and a loop of wire material extending around thebale is usually obtained by providing that wire material from two sources and extending along opposite sides of the bale to be formed is tied together near the downstream end of the bale to be formed and is tied together near the upstream end of the baleafter the material for forming that bale has been pressed.The tying together is usually accomplished by twisting or twining end sections of the wire material from a mutually parallel configuration.An example of a mechanism for tying of bales is for instance described in U.S. Pat. No. 3,667,377. In this mechanism, twisters for twisting the wires are provided in the form of twisting hooks supported by a twister frame that is guided formovement vertically (i.e. towards and away from the bale) by means of hydraulic rams.Also according to E

Method, An Apparatus And A Means For Making A Reinforcement Mesh - Patent 7909067

Patents-433 — Sat, 23 Apr 2011 03:53:26 GMT

shared by: Patents-433 on: Saturday, April 23, 2011

THE PRIOR ART The invention relates to a method, an apparatus and a means for making a reinforcement mesh, in particular for use in concrete structures, said mesh comprising reinforcement bars which are held together by means of a flexible holding means so asto form a mesh comprising held bars at a desired mutual distance, said holding means being formed by two wires which extend respectively above and below each individual reinforcement bar, and which, when being twisted, are clamped around the individualbars. Reinforcement work constitutes a considerable factor in connection with reinforced concrete work. In an attempt at reducing the costs in connection with reinforcement work it is known to make reinforcement meshes which may partly be roiled up to facilitate storage and transport and may partly be mounted in a relatively simple manner. This mesh may be made by means of mounted holding means for the individual bars so that these may be attached relatively easily to the holding means at the desired point, or in that the individual bars are secured to a carrying band. Then, the assembled reinforcement may be arranged at the desired point. However, all previous attempts at simplifying the reinforcement work suffer from various drawbacks. Where joining is concerned, this takes place by welding which involves damage to the surface of the bars. This is a drawback when the bars are surface treated with corrosion protection, which is destroyed thereby, and, in addition, the bars areweakened at the points concerned. Where bands are used as a holding means, these must normally be tack welded, which is both cumbersome and time-consuming. Japanese published application No. 2001 182220 discloses a reinforcement mesh consisting of reinforcement bars which are held together by means of twisted wires. This known structure describes a mesh which is held together by twisted wires, which wires, however, are wound around "loose" reinforcement bars and thereby provide no certainty

Jaw For Sealless Strapping Machine - Patent 7900657

Patents-433 — Fri, 22 Apr 2011 13:09:11 GMT

shared by: Patents-433 on: Friday, April 22, 2011

The present invention is directed to a jaw for use in a sealless strapping machine for forming a sealless seal. More particularly, the present invention is directed to a one-piece jaw for forming a sealless seal. Strapping machines are in widespread use. Typically, strapping machines are designed for use with metal (steel) or plastic strapping. In use, strapping is wrapped around the load, tensioned and sealed to itself. In use of metal strapping, theseal can be formed by use of a separate seal that is positioned around the strap and crimped onto the overlapping courses of strap. The seal can also be formed by gripping the strap material sections between a punch and the strapping machine jaw andcutting portions of the over- and under-lying courses of strap material into one another to interlock the strap courses. Such a seal is referred to as a sealless seal. This action creates a locking action that provides additional strength to the strap, so that the tension in the band is maintained. The geometry of the jaw is highly engineered and does not lend itself to change. The jaws, by the nature of thedesign, experiences extremely high fluctuating stresses, that can result in fatigue failure if the maximum tensile stresses at the shear section exceeds half the shear yield strength. There are tremendous gains to be had if the stresses stay at or below1/2 the yield strength. Failure of the jaws can occur by fracture at the interface of the punch with the jaw structure. Again, this is due to the high localized stresses that are exhibited at this juncture. In order to address this, it has been thought that abuild-up of material (e.g., making the jaw thicker) at the juncture would preclude or lessen the chances of the jaw failing. While this has increased the jaw life, it results in other undesirable characteristics, namely, the jaws have become too largeand heavy and the space for the strap to move into the jaw area and for the strap to reside during the sealin

Wiring in branch circuits generally serves multiple devices with varied electrical loads. Hence, wiring runs from one electrical device to another devicewithin the branch circuit rather than directly from the electrical panel. As a result, the wiring is discontinuous due to the termination of one or more conductors at each electrical device. Therefore, to achieve a continuous branch circuitnecessitates an electrical connection at each electrical device.Electrical wiring may also be discontinuous due to presence of one or more sub-branches within a branch circuit. Sub-branches may lead to such electrical devices as receptacles, switches, lights, fixtures, and so on. Similar to discontinuitiesin a branch circuit, a discontinuity in a sub-branch necessitates an electrical connection. As a result, the wiring is discontinuous due to the termination of one or more conductors at the sub-branch (or junction). Therefore, to achieve a continuouscircuits necessitates a connection at the sub-branch or junction.In some cases, a branch circuit may be dedicated to a single electrical device (or load) such as a major appliance. Yet, wiring may still be discontinuous due to accidental damage to wiring, unanticipated terminations of conductors, alterationsto electrical plans, and/or partic

shared by: Patents-433 on: Saturday, October 30, 2010

The present invention relates generally to electric wire harness fabricating apparatus, and more particularly, relates to an apparatus for feeding a wire or wires from a wire supply to a wire harness fabricating device.As is well known, electrical harnesses are provided with a plurality of wires, both ends of which are attached to connectors referred to commonly as a "master" and a "slave" connector and which are used to connect electronic apparatus together byconnecting two connectors thereof to the connectors of the apparatus.The two connectors and wires are held in the wire harness by press-fitting the end portions of the wires into contact with terminals of the two and this is referred to as "pressure welding". The master and the slave connector are formed in arectangular shapes in a direction orthogonal to the longitudinal direction the wires. The wires are aligned in a longitudinal direction of the connector on the same line by a pitch of a unit of several millimeters and the wires are pressure-welded tothe connector terminals.Pressure welding of the wires and the connectors is carried out by known pressure welding apparatus. The wires are supplied from wire spools provided at a wire supply apparatus to the pressure welding apparatus by a predetermined length. Thesupply amount is normally matched to a length of the wire disposed on the outermost side of the electric harness. The wire is supplied to the pressure welding apparatus by a pair of upper and lower feed rollers which rotate and the wire utilizingfrictional forces produced between the rollers and wire.The rollers are rotated by utilizing a drive source with a servo motor. When the servo motor is rotated, the servo mechanism is operated in accordance with a rotational number thereof to thereby rotate the rollers. The amount of wire reeledfrom the rollers is calculated in accordance with the number of rotations of the servo motor. As is known, the servo mechanism refers to a mechanism which is ma

1. Field of the InventionThe present invention relates generally to band tightening devices, and more particularly is a plastic band tightening device with an improved cutting mechanism.2. Description of the Prior ArtThe prior art includes several devices that utilize known methods of cutting a strapping band. Some references representative of the prior art are disclosed in U.S. Pat. No. 4,644,646 to Eli M. Ladin; U.S. Pat. No. 6,047,742 to Barlasov;U.S. Pat. No. 6,962,108 to Hsiu-Man Yu Chen; and U.S. Pat. No. 7,100,499 to Hsiu-Man Yu Chen.These prior art devices teach a design such as that shown in FIG. 1. The device in FIG. 1 includes a frame 1', a cutting mechanism 2', a tightening mechanism 3', and a band holding mechanism 4'. The cutting mechanism 2' comprises a stationarycutter 21', a pivoting cutter 22' mounted inside the stationary cutter 21', and an actuating lever 23' mounted on the pivoting cutter 22'.To begin a banding cycle, the operator pushes down on a handle 31', which raises the gripper 41' and allows the user to insert the first end 61' of a band 6' between the gripper 41' and the frame 1'. When the user releases the handle 31', thegripper 41' holds the first end 61' of the band 6' in place.During the tightening operation, the second end 62' of the band 6' is threaded trough the cutting mechanism 2' and a windlass 32' of a tightening mechanism 3'. The operator applies force to the handle 31' and tightens the band 6'. Whensufficient pulling force has been applied, and the two ends 61', 62' of the band are secured with the seal 5', the operator presses the handle 31' down a second time to trigger the actuating lever 23' so that the pivoting cutter 22' cuts the second end62' of the band 6'.A significant drawback in the prior art design is that the two cutting edges 21', 22' of the cutting mechanism 2' interact two times during each operational cycle. The first time the two cutting edges 21', 22' contact each other is when theoperator

Numerous techniques and configurations for wire and filament crimps are known. For example, U.S. Pat. No. 5,486,653 to Dohi issued Jan. 23, 1996 entitled "Crimp-styleterminal" discloses a crimp-style terminal crimped to connect itself with an end of an electric wire includes an electric connecting part which is electrically connected to the other connecting part; and a crimping part formed integrally with theelectric connecting part. The crimping part includes a bottom part and a pair of bends protruding from both sides of the bottom part. Each of the bends is formed to be thinner than the bottom part. In crimping, the pair of bends are deformed in such amanner that each end of the bends is directed to a substantially intermediate position in the width direction of the bottom part, whereby the end of the electric wire is crimped to the terminal securely.U.S. Pat. No. 6,004,171 to Ito, et al. issued Dec. 21, 1999 and entitled "Crimp-type terminal" discloses a crimp-type terminal for electrically connecting an internal conductor to a mating terminal, includes: an electrical connection portionfor fitting connection to the mating terminal; a conductor clamping portion having a base plate, and upstanding walls which extend respectively from opposite side edges of the base plate, and are pressed to clamp the interna

Patents-433 — Mon, 18 Oct 2010 10:16:44 GMT

shared by: Patents-433 on: Monday, October 18, 2010

FIELDOF THE INVENTIONThis invention relates to a fabrication of a medical instrument for removing an object from a body, and in particular, to a fabrication of a surgical device for extracting calculi appearing in the biliary or urinary system.BACKGROUND OF THE INVENTIONOne type of a widely used surgical device is a tool for retrieving foreign material from various sites along the urinary tract of a patient's body. Examples of the foreign material include calculi of different sizes and characteristics.Referring to FIG. 1, a schematic view, partially in a longitudinal cross-section of the distal end of an example of a conventional surgical retrieval tool is illustrated. The surgical retrieval tool 10 or so-called surgical extractor, generallycomprises a flexible tubular catheter 11 formed as a tubular sheath adapted to penetrate the body passages to reach the location where the object (not shown) to be evacuated is located. A manipulation rod or cable 12 is located within the catheter 11,which can be manipulated from the outside at the catheter's proximal end. The rod 12 is coupled to a basket 13 capable to be deployed within the sheath. The basket 13 consists of flexible filaments 14 and, for example, can be made of either stainlesssteel or any other material capable to provide the basket with elasticity. According to the example shown in FIG. 1, the filaments 14 are bound together in the vicinity of a basket proximal end to form strands 19 as well as at a basket distal end toform a tip 15. The basket 13 is usually connected to the manipulation rod 12 via a sleeve connector 17 bounding the strands and filaments together.One of the drawbacks of the conventional surgical extractor is associated with the discrepancy of the inner diameter of the catheter 11, the diameter of the manipulating rod 12 and the diameter of the connector 17. Due to this discrepancy, anair gap 18 between the inner wall of the catheter 11 and the rod 12 significantly affects deformation

Machine For Continuously Manufacturing A Welded Metal Trellis - Patent 7594523

The present invention relates to a machine for continuously manufacturing a strip of welded metal trellis with the aid of a single metal wire, as well as a manufacturing method foroperating said machine and, finally, the resultant single-wire welded metal trellis.Lattices of this type lend themselves to a broad variety of possible applications, in particular due to their decorative appearance, and may be used in gardens or public places, houses and public or private buildings and, more generally, in anytype of construction frequented by man.Currently, lattices are generally produced by machines which use a plurality of longitudinal wires which are unreeled from several separate reels and placed in a parallel arrangement. The number of these reels is variable and is traditionallybetween eight and forty eight, depending on the dimensions of the trellis or lattice, and in particular depending on its width, which is determined by the number of wires. After placing said longitudinal wires in a parallel arrangement, secondary wiresare welded transversely on a level with their intersection points with the aid of spot welding devices. The resultant trellis has square or rectangular meshes, the dimensions of which depend on the spaces left free between the longitudinal wires and thetransverse secondary wires. Such meshes naturally always necessarily have right-angled corners.This construction technique has a certain number of disadvantages: The construction process requires the use of several wires and reels, which means that equipment has to be adapted and an appropriate space made available in front of theproduction machine. Furthermore, using a large number of wires and reels in parallel complicates the process and slows down production, especially because each wire has to be straightened and the unreeling operation controlled. It is no longer possibleto produce a large variety of ornamental motifs in the meshing of this lattice because it is only possible to make r

1. Field of the InventionThe present invention relates to a device for bending a wire to be used in the fabrication of a removable orthodontic appliance. More particularly, the device is for use in fabricating a retainer of the type having a wire against the labialsurface of the upper or lower anterior teeth.2. Brief Description of the Prior ArtAt the present time, the procedure for making a removable orthodontic appliance is as follows. First, an impression of the teeth is made, from which is molded a plaster model of the patient's teeth. Wires are then shaped and adapted to themodel and an acrylic plate is formed over the tag ends of the wires.A labial bow is an important element in a Hawley retainer and is used in many other orthodontic appliances. When the retainer includes a labial bow, a length of wire is cut and a pair of vertical loops are formed in the canine areas separated byan incisor segment. The vertical loops ideally consist of parallel legs joined by a smooth curve. The loops are symmetrical and extend a short distance above the gingival margin. Either before the vertical loops are formed or after, the incisorsegment is curved such that it passes across the labial surface of the incisors at the widest portion of the teeth just incisal to the interdental papilla. The wire should form a smooth arc, as symmetrical as possible while conforming to the curve ofthe labial surfaces of the incisors. Special pliers such as 139 pliers are used to form the vertical loops and a turret may be found helpful in shaping the incisor segment.Making a proper labial bow requires skill and it is desirable to keep time to a minimum. Quality is improved if repeated bending is eliminated because repeated bending of the wire can lead to strain hardening and weakening in certain metals. Quality is also improved if handling of the wire by wire forceps is kept to a minimum as damage to the wire may lead to increased likelihood of breakage.BRIEF SUMMARY OF THE INVENTI

FIELDThis disclosure relates generally to an apparatus for forming a wire, and more particularly to an apparatus for forming a wire that is useable in a dynamoelectric machine.BACKGROUNDDisposal of copper wire in slots of a stator core of a dynamoelectric machine requires a forming or shaping of the wire before insertion into stator slots. Typically, the wire is formed to include a plurality of coil segments. These coilsegments are commonly formed in the wire via a rotating, barrel type device, onto which unformed wire is fed. The rotating device generally includes a plurality of forming protrusions that contact the wire to form the coil segments, wherein the coilsegments are formed one at time over the protrusions, as the wire is rotated/fed onto the rotating device.An obvious drawback to forming coil segments one at a time is the amount of time the process takes as compared to a process that could form a plurality of coil segments simultaneously. Therefore, a method and apparatus that could simultaneouslyform a plurality of coil segments in a copper wire would be desirable.BRIEF SUMMARYDisclosed is an apparatus for forming a wire to include coil segments useable in a dynamoelectric machine, the apparatus including a plurality of forming structures simultaneously moveable along an axis into a coil segment forming configuration,with at least a number of the plurality of forming structures being configured to hold a wire, and at least one actuating device associated with at least a number of the plurality of forming structures and configured to simultaneously move the number ofthe plurality of forming structures into the coil segment forming configuration.Also disclosed is a method for forming a wire to include coil segments useable in a dynamoelectric machine, the method including simultaneously forming a plurality of coil segments in a generally linear configuration.Further disclosed is an apparatus for forming a wire to include coil segments, the apparatus inc

FIELD OF THEINVENTIONThe present invention relates to the field of tools, and in particular, relates to a tool for twisting the wire ties which are used to hang suspended ceilings and/or other various ceiling components, such as light fixtures, fans, and the like.BACKGROUND OF THE INVENTIONCurrent practice in the construction trade and building industry is to suspend ceiling tiles, acoustic ceiling tiles, fixtures, and the like, with wire ties that are fastened at one end to a bracket which is affixed to building structure such asa ceiling joist, a concrete or masonry pad used to form the roof or floor above, a ceiling panel support grid, and/or brackets affixed to these surfaces. Typically, one end of the wire ties is attached to the support structure and the other end hangsdown from this structure. The wire ties are commonly made of from 8 to 12 gauge steel, or the like, and is reasonably resilient in order to provide the strength needed to support the weight of the ceiling or ceiling components. Because a relativelylarge variety of equipment can be hidden above a suspended acoustic tile ceiling in a commercial building, the wires ties can vary in length from 18 inches to over six to eight feet. Thicker gauge wire ties can also be used in some applications.In use, the user inserts the hanging free end of the wire tie though a ceiling support bracket, or the like, and then twists the wire around itself in order to hold the wire tie in position. This is commonly done by hand, or with the aid of apair of pliers.The most apparent disadvantage of this technique is the cost of labour for the labour intensive task of twisting the wire. For example, in order to be reasonably secure and satisfy some municipal codes, approximately six to eight inches of thewire must be twisted eight to ten turns about itself. In practise, because of the stiffness of the wire tie, it is difficult on the user to use his fingers to twist each wire tie around itself eight or ten times; -

Apparatus And Method For Forming Wire - Patent 7617847

Patents-433 — Sat, 16 Oct 2010 01:54:59 GMT

shared by: Patents-433 on: Saturday, October 16, 2010

The present invention relates to improved types of wire and particularly to an apparatus and method for forming wire.BACKGROUND AND SUMMARYWire is often used to electrically couple various components. A number of factors affect the electrical and physical characteristics of wire. The greater the current carrying capacity required, the more metal needed, such as copper, steel,silver, gold, aluminum, brass, nickel, copper clad steel, stainless steel, or any alloys and platings thereof. Conversely, the more metal in the wire, the stiffer and less flexible the resultant single strand wire. The less flexible the wire, thegreater the work hardening of the metal due to bending and the lower the flex life (i.e., service life).To overcome this hurdle, cable designers often replace a large gage single strand wire with a multitude of smaller strands, twisted into a flexible cable. The resultant product carries the same electrical current but is easier to manipulate andhas the added benefit of a longer flex life.There are tradeoffs, however, between improved flexibility and other physical properties. For example, the stranded wire will have a serrated exterior surface. Since the wire is formed from a plurality of strands twisted together, the exteriorsurface does not have a continuous round surface as that of a single strand wire. This is due to the gaps (also known as interstices) between the single ends in the twisted cable. To meet the minimum insulation thickness required by the end user, andto create the necessary round shape of coated wire, more insulation must be injected into the gaps between the strands of wire on the exterior of the wire. This results in a net waste of insulation materials. Thicker insulation also serves to reducethe flexibility of the end product.Wire made of multiple strands also has a lower elongation, and a lower yield strength than a single strand of wire with equivalent cross sectional area. This means that stranded wire pulls apart

1. Field of the InventionThe present invention relates, in general, to methods and devices for cutting cable ties and, more particularly, to a cable tie cutting method and a cable tie cutter for executing the method, which only require small cutting force during a cabletie cutting process, thus reducing impact applied from the cutter to the wrist and elbow of a user when cutting cable ties, so that the user can easily and conveniently cut the cable ties and the wrist and elbow of the user are protected from overloadand overstress, and thus the user can avoid workmen's accident on the wrist and elbow.2. Description of the Related ArtGenerally, as shown in FIG. 1, to cut a cable tie using a conventional cable tie cutter, a user presses a trigger lever 92 of the cutter backwards by fingers such that a cable tie holder 91 of the cutter, which holds a cable tie, is retractedalong with the cable tie and draws the cable tie backwards. When the cable tie is fully drawn backwards by the holder 91 and is completely tightened, the cable tie holder 91 is not further retracted, so that the trigger lever 92, which has been pressedby the fingers of the user to tighten the cable tie, is tensioned and is not likely to be further moved backwards. Thus, in the above state, the user must press the trigger lever 92 backwards with increased force so as to move the lever 92. To cut thecable tie after completely tightening the cable tie, a cable tie cutting blade 93 must be operated. To operate the cable tie cutting blade 93, an actuating link 94 must be actuated by a triangular link 96, which is rotated counterclockwise around ahinge pin 95, acting as a hinge shaft, and escapes from a spring-biased base block 98, which is biased by a return spring 97. Thus, in the above state, the user must press the trigger lever 92 backwards by his/her fingers with strong power such that themuscles of the wrist, elbow and hand of the user are overloaded and overstressed when the user repeats the

1. Field of the InventionThe present invention relates generally to chain link fabrics and, more particularly, to an improved chain link fabric with flattened ends and a method and apparatus for forming the flattened ends of the fabric.2. Description of the Related ArtIt has been estimated that throughout the world, millions of square feet of chain link fabric are produced and sold annually. Recognizing the importance of providing effective and durable chain link fabric, the American Society for Testing andMaterials (ASTM) has established minimum quality standards for both residential and commercial chain link fabric. Realizing that chain link fabric can be effective for various different applications, the fencing and chain link industry has developedmany different types of chain link fabric. Each type of chain link fabric has specific features that provide additional advantages when the fabric is used for its intended purpose.Typically, chain link fabric is used as a barrier. When it is used as a barrier, it is typically used with some type of support member, such as a fence frame, that holds the fabric in place. Also, chain link fabric commonly is used to controlor prevent the movement of nearby objects. For example, chain link fabric often is used in land fills and mines, and on land to control rocks, boulders, and soil.Traditionally, chain link fabric is produced using a weaving machine. A typical weaving machine continually feeds two strands of wire into a weaving blade and trough mechanism that bends and weaves the two wires together. The weaving blade andtrough interweave the two wires by helically winding them to provide a continuous mesh, without knots or ties, except possibly at the edges of the finished fabric. After being woven together, the formed continuous links of chain link fabric are cut offat the edges, leaving sharp wire-end portions. How the edges of the fabric are finished is generally referred to as the selvage. Typically, the sel

shared by: Patents-433 on: Thursday, October 14, 2010

FIELD OF THEINVENTIONThe present invention relates generally to devices that are used to bend wire of a wire fence. More particularly, the present application involves a device for bending wire of a wire fence in order to tighten or increase the tension, and hencereduce sagging, of the wire fence during installation and/or repair.BACKGROUNDFarmers and property owners commonly install wire fence in order to demarcate the boundary of property or to confine animals. Installation of a wire fence, especially over rough terrain, generally requires the step of tightening the wire afterit is secured to a post. For example, when a section of wire fence is positioned up a hill the top of the wire fence is generally tight while the bottom of the wire fence is loose.Common practice is to tighten the wire of the fence with the use of pliers, screwdrivers, and/or claw hammers. In this regard, the installer twists a loose wire in order to put a bend into the wire so as to consequently decrease the length ofthe wire between the fence posts and thus increase tension. The installer makes as many bends in the wire as necessary in order to achieve a desired tension.Wire fence may become damaged by being hit by animals, automobiles or other equipment. Additionally, falling trees brought about by storms may also hit installed wire fence thus causing it to sag. Still further, wire fence may begin to sag overtime thus necessitating repair. In these instances, one or more posts of the wire fence may be pushed out of position thus resulting in sagging of the wire connected therewith. In order to repair wire fence it is sometimes the case that the repairerloosens the wire from its attached post and subsequently pulls the wire tight with the use of a lever or winch device. Next, the repairer re-attaches the wire to the post. Such attachment generally involves the use of a hammer to drive a plurality ofstaples into the post in order to secure the wire thereon.Current methods of incre

SThis application is a National Phase Application (35 USC 371) of PCT/JP2004/005650 and claims priority of Japanese Application No. 2003-116222, filed Apr. 21, 2003.TECHNICAL FIELDThe present invention relates to a coil forming and insertion device and to a method for forming a coil and for inserting and arranging this coil in a stator core to be incorporated into an electric motor.BACKGROUND ARTIn the manufacture of a motor having a stator with slots for insertion of plural monopole coils into slots of the stator core, a multipole coil is formed by joining the plurality of the monopole coils.In a conventional coil forming method, a winder guiding an electric wire (wire) travels around a fixed winding frame, and the electric wire is wound around the winding frame to form the monopole coil.JP-A-2000-253631 discloses a winding apparatus including a winding frame with a changeable outside diameter and a flyer which is rotated around the winding frame. The coil with joined poles (multi pole coil) for use in a motor is formed bysequentially dropping the wound monopole coil onto a blade.However, in the winding apparatus of JP-A-2000-253631 when the monopole coil is dropped onto the blade, the monopole coil is intended to drop into a clearance between needles of the blade from the winding frame positioned above the blade. However, there exists the possibility that, in certain cases, the monopole coil can not drop to the clearance. Accordingly, transfer and mounting of the monopole coil is unreliable. Further, in certain cases, when the monopole coil drops onto theblade, the order of the electric wires in this monopole coil will change from the winding order in which the wires were wound.Further, in the method of JP-A-2000-253631, after one monopole coil is formed on one winding frame, this monopole coil is dropped in sequence onto the blade. Therefore, there is the possibility that the lengths of the connecting wires connectingthe respective monopole coils together wi

The present invention is related to a reinforcing bar binding machine. More particularly, the present invention is related to a reinforcing bar binding machine having a warming-up function so as to prevent the occurrence of failure in operationin a low temperature environment.BACKGROUND ARTIt is a matter of general knowledge to appropriately use lubricant for a rotary shaft, a sliding face of a piston and a frictional face of a gear or a cam in a power tool such as an electric tool or a pneumatic tool. Concerning this matter, forexample, refer to JP-A-2003-136435. In the case of lubrication of a rotary shaft or a sliding member, the sliding speed of which is relatively low, to which a heavy load is given, provided in a binding wire twisting mechanism of a reinforcing barbinding machine, grease of higher viscosity is used.In the case where the reinforcing bar binding machine is used outside where a temperature is very low, the viscosity of grease is increased and a sliding resistance of a rotary shaft or a sliding member is raised. Accordingly, it becomesimpossible to exhibit the original performance of the binding machine. In the environment of low temperature, a battery voltage is reduced and an output of a motor is lowered. Accordingly, in addition to the increase in the viscosity of grease, due tothe reduction in the battery voltage, an operation speed of a mechanism portion is decreased and further an operating force of the mechanism portion becomes weak. Consequently, there is a possibility that failure in operation is caused and further itbecomes impossible to start the binding machine.DISCLOSURE OF THE INVENTIONTherefore, one or more embodiments of the present invention provide a reinforcing bar binding machine in which no failure in operation is caused even when the reinforcing bar binding machine is used in a cold environment.According to one or more embodiments of the present invention, a reinforcing bar binding machine is provided with: a binding w

The present invention relates to a tool for installing metal locking ties, and more particularly to a tool for installing metal locking ties with a rotary gripper for tensioning the metal locking tie, a device for setting the ball in the metallocking tie and a device for shearing the metal locking tie tail.BACKGROUND OF THE INVENTIONAs is well known to those skilled in the art, cable ties, or straps are used to bundle or secure a group of articles such as electrical wires and cables. Cable ties of conventional construction include a cable tie head and an elongated tailextending therefrom. The tail is wrapped around a bundle of articles and thereafter inserted through the passage in the head. The head of the cable tie typically supports a locking element, which extends into the head passage and engages the body ofthe tail to secure the tail to the head.In practice, the installer manually places the tie about the articles to be bundled and inserts the tail through the head passage. At this point, a cable tie installation tool is used to tension the tie to a predetermined tension. The tools ofthe prior art, although capable of tensioning and thereafter severing the excess portion of the cable tie, typically have several disadvantages therewith. As a result, it is desirable to provide a metal tie tool having an improved ball set and cut-offmechanism. It is also desirable to provide a metal tie tool having an improved tie tensioning mechanism.SUMMARYA tool for installing metal locking ties is disclosed. The tool includes a tensioning mechanism and a ball set and cut-off mechanism. The tensioning mechanism tensions a metal locking tie around a bundle. The ball set and cut-off mechanismincludes a guide block and a shear block that engages the guide block. Once the tool tensions the metal locking tie, a ball set and cut-off handle is manually activated to push the guide block and the shear block forward in the tool to engage the metallocking tie head.

Manual Tensioner For Non-metallic Straps - Patent 7455080

Patents-433 — Tue, 12 Oct 2010 06:46:47 GMT

shared by: Patents-433 on: Tuesday, October 12, 2010

The present invention relates to a manual tensioner with a cutter that may be used to apply a non-metallic strap around a load and to cut the strap from a strap supply.Straps are wrapped around loose objects, such as lumber, to bind the objects together. Straps are also wrapped around boxes and other items to package and secure the boxes and items together. Straps of different materials are often used totighten different types of loads. For example, plastic straps are often used to tighten lumber loads and boxes. Tensioners are used to tighten or tension the straps around the load. Further, there are tensioners designed for metallic straps and othersfor plastic or non-metallic straps. A hand-held or manual tensioner is typically used when a load is to be tightened in the field, such as the one shown in FIG. 1.Non-metallic hand held tensioners of the art are able to tighten the strap around the load, but they suffer from many shortcomings. For example, after wrapping the strap around the load, it is desirable to manually pull the strap to remove anyexcess slack. This typically reduces the time and number of steps required to complete a strapping operation, i.e., to tighten the strap around the load. However, prior art tensioners used with non-metallic straps incorporate gear box assemblies thateither did not allow for manual slack reduction or incorporated very cumbersome slack reduction mechanisms. In other words, after the strap is wrapped around the load and fed into the tensioner, the user either cannot pull an end of the strap tomanually remove excess slack or cannot remove excess slack without exerting great effort.In addition, other tensioners of the art incorporate a double strap or a strap-on-strap loading mechanism. A first portion of the strap is held in place by a gripper, and a down stream portion of the strap is wrapped around the load andpositioned over the first portion. This forms a top strap layer, and the portion of the strap underneath

This application is a 35 USC 371 of PCT/JP05/12500 filed Jul. 6, 2005.TECHNICAL FIELDThis invention relates to a reinforcing bar binding machine, and more particularly to a reinforcing bar binding machine in which a number of turns of a wire to be wound around reinforcing bars can be set arbitrarily.BACKGROUND ARTAs labor-saving means for a reinforcing bar binding work, there is an electrically-driven reinforcing bar binding machine for winding a wire around reinforcing bars to bind these reinforcing bars together. One kind of reinforcing bar bindingmachine is provided with a wire feed mechanism, a wire cutting mechanism, and a wire twisting mechanism, and a wire is fed along a guide nose of a curved shape by the wire feed mechanism, so that reinforcing bars are surrounded by a wire loop, and thewire loop is cut off from the wire extending from a trailing end of the wire loop by the wire cutting mechanism, and at the same time the wire loop is twisted by the wire twisting mechanism to bind the reinforcing bars in closely contacted relationthereto.The wire feed mechanism employs a pair of V-grooved gears disposed in mesh with each other, and one of the V-grooved gears is driven by a motor, and the other V-grooved gear of a follower type is resiliently contacted with the one V-grooved gearsuch that the wire is held between the two V-grooved gears, and these V-grooved gears are driven for rotation so as to feed the wire (JP-A-2003-054511, JP-A-2003-267307, etc.). The amount of feed of the wire is controlled on the basis of a number ofrevolutions of a feed motor or the V-grooved gears, and is set, for example, to an amount corresponding to 4 turns plus .alpha., and each time a trigger lever is pulled, the wire is fed in an amount corresponding to 4 turns plus .alpha. (which amount isequal to 3 turns around the reinforcing bars plus an additional amount for binding purposes), thereby effecting one cycle of binding operation.In the above reinforcing bar binding machin

Patents-433 — Sun, 10 Oct 2010 00:54:36 GMT

shared by: Patents-433 on: Sunday, October 10, 2010

The present invention relates to a method of manufacturing electrical bundles (or harnesses), to apparatus adapted to such manufacture, and to electrical bundles or harnesses obtained thereby.The technical field of the invention is that of manufacturing electrical harnesses for rotary wing aircraft.BACKGROUND OF THE INVENTIONA helicopter is commonly fitted with one or more hundreds of electrical harnesses, and they can all be different from one another.An electrical harness is usually made up of lengths of sheathed (insulated) electrically conductive wire collected together and/or tied together so as to form distinct portions, or branches, of the harness; the harness also generally comprisesone (or more) electrical connectors disposed at a free end of at least one of the branches; each connector is mechanically secured to the end of at least one of the wire segments forming the branch in question; a connector includes at least one male orfemale electrical connection member (or terminal) which is in electrical contact with the end of one of the segments of wire, e.g. by being crimped thereto, and possibly after said end has been stripped.Manufacturing a harness essentially consists in bringing together and/or uniting wire segment portions so as to build up the branches of the harness, and in fitting suitable connectors to the ends of the branches of the harness, whereappropriate.The manufacture of an electrical harness for a helicopter generally also includes an operation of providing the branches with electromagnetic or mechanical protection by means of a braided sheath.Such protection makes the harness stiff, and thus makes it difficult to put the harness into place. To mitigate this drawback and to leave a degree of flexibility to the harness, it is necessary to twist the cables making it up prior to braidingon the sheath.As a general rule, in order to manufacture a harness, use is made of a plane support, such as a bench or table, to support the electrical harne

shared by: Patents-433 on: Saturday, October 09, 2010

1. Field of the InventionThe present invention is broadly concerned with wire strapping apparatus of the type used to apply knotted and tensioned wire ties to preformed bales such as compressed refuse bales. More particularly, the invention is concerned with suchapparatus having features permitting quick and easy access to critical wire knotting components, so that the user may readily clear, repair and/or replace such components as necessary.2. Description of the Prior ArtVarious wire tying and strapping machines have been proposed in the past for applying knotted and tensioned wire ties to bales, packages or other articles. One class of these prior machines makes us of a continuous, two-piece wire track with anassociated strapping device. In such units, a package or bale to be tied is positioned within the confines of the wire track, and a continuous strand of wire is advanced completely around the track and overlapped with itself. The wire is then tensionedand the overlapped sections are knotted together by twisting. This further tensions the wire to the point that the track sections are separated allowing the knotted and tensioned tie to snap into place about the bale or article. In some cases morecomplex devices are provided for ejecting the knotted wire from the track.Commonly, a twister pinion is employed for twist-knotting of adjacent wire sections. Such a knotter pinion includes a slot to accommodate the wire sections and upon rotation of the pinion a defined number of turns or twists are created. Inorder to maintain the wires in the twister pinion and associated structure, a shiftable knotter cover located adjacent the twister pinion is used.A significant problem with prior machines is the difficulty of readily clearing or servicing the twister pinion and related structure. Hence, in one prior machine design, it is necessary to physically detach the cover and disassemble the pinionapparatus for servicing purposes. In other instances, the cover

Low Tension Flush Cut-off Cable Tie Installation Tool - Patent 7422037

Patents-433 — Sat, 09 Oct 2010 08:58:52 GMT

shared by: Patents-433 on: Saturday, October 09, 2010

Most cable tie application tools apply a predetermined tension to a cable tie encircled about a number of loose objects before cutting away an excess portion of the cable tie tail. As it is desirable to not have the cut edge of the tie, which isoften sharp, protrude from the head, thereby posing a danger to people and nearby objects, the tails are generally cut fairly close to the head such that the tension in the applied cable tie will cause the sharp edge of the tail to recede into the cabletie head. When this occurs, a desirable "flush" cut-off has occurred.While many cable tie applications require the tie to tightly bind the loose objects, there are also some important low-tension applications, such as where high tension might cause damage to the bundled objects. For example, it is sometimesimportant that cable ties not be applied so tightly so as to deform a cable sheath, as in the case of bundling twisted pair copper wires. Sometimes it may be desirable to slide an applied cable tie along the length of a cable bundle, such abilityrequiring a more loosely applied cable tie. Though application tools exist wherein one can lower the predetermined tension to an acceptable level for such applications, the lower degree of tension stored in the cable ties often provides insufficientspring-back ability to cause the cut edge of the tail to recede back into the head, thereby leaving a sharp protruding edge.SUMMARY OF THE INVENTIONTo address shortcomings of prior tools and provide performance advantages relative to prior tools, there is provided a cable tie application tool that provides for flush cutoffs in low tension cable tie applications. Specifically, the inventivetool has a special design that permits a tail cutoff point that is closer to the head than in prior designs such that the lower spring-back power of the low-tension applications is sufficient to cause the cut end of the tail to recede into the head ofthe tie.In one embodiment of the invention, there

shared by: Patents-433 on: Friday, October 08, 2010

The present invention relates to an apparatus for automatically binding reinforcing rods capable of automatically accomplishing a wire fastening operation used for securely binding the reinforcing rods used in a building construction or civilengineering works to each other.BACKGROUND ARTIn a prior art, a worker binds reinforcing rods with a wire to securely fasten the reinforcing rods to each other prior to pouring operation of concrete slab in a construction field. In order to accomplish the binding operation, those skilled inthe art use a binding hook to wrap a crossing part of the reinforcing rods with the wire and twist both ends of the wire with the binding hook.However, this operation is, as circumstances require, accomplished at a place far from the ground, and a binding performance of the reinforcing rods is different from depending upon an expertness of the operator, thereby requiring a high wagesmore than operators of the other processes. Therefore, a construction cost is increased, and an industrial disaster such as an injury from a fall of the operator occurs.Therefore, the applicant of the present invention has proposed Korean Patent Application No. 2002-0032614 entitled "Apparatus for automatically binding reinforcing rods and a binding-wire used therein" in order to accomplish this operationwithout an individual skill.Referring to the above patent, the apparatus comprises a case having an inserting groove in which a reinforcing rods is inserted, binding-wire receiving means installed at one side of the case and in which the binding-wire is stored, binding-wirefeeding means installed at one side of the case to extract the binding-wire forward, and a rotary binding-wire guider installed at a front end of the case to rotatably guide the binding-wire supplied from the feeding means to surround the reinforcingrods.Further, a fastening fan having a plurality of wings is closely installed at one side rear end of the rotary binding-wire guider and rotatably

The present invention relates to wire fences such as barbed-wire fences which include runs of wire that are attached to fence posts inserted in the ground. More particularly, the present invention relates to a twist attachment device which issuitable for attaching barbed wire to a fence post by wrapping an attachment wire segment around the barbed wire on opposite sides of the fence post with the fence post interposed between the attachment wire segment and the barbed wire.BACKGROUND OF THE INVENTIONBarbed wire fences are widely used to define boundaries on land areas for the purpose of keeping livestock or other animals inside the fenced-in areas and keeping predatory animals or unauthorized personnel out of the areas. Typically, a barbedwire fence includes multiple vertically-spaced horizontal runs of barbed wire which are supported at spaced intervals by vertical fence posts extending from the ground. Each of the barbed wire segments is attached to each fence post typically usingclips which engage the barbed wire and the fence post. Because these clips must be individually inserted in place on the fence posts, construction of a barbed wire fence is a time-consuming and labor-intensive undertaking.SUMMARY OF THE INVENTIONThe present invention is directed to a twist attachment device which is suitable for attaching a segment of fence wire such as a run of barbed wire to a fence post in the construction of wire fences. The device includes a frame within which isrotatably mounted a pair of spaced-apart wire twist gears each having a wire notch and a wire segment opening adjacent to the wire notch. A drive mechanism operably engages the wire twist gears to rotate the wire twist gears in the housing. Inoperation, an attachment wire segment is extended through the registering wire segment openings of the respective wire twist gears, after which a fence post is extended between the spaced-apart wire twist gears.

Cassette Pigtailing Machine For A Coil Spring - Patent 7198068

Patents-433 — Wed, 06 Oct 2010 09:41:05 GMT

shared by: Patents-433 on: Wednesday, October 06, 2010

The present invention relates to the forming of a coil spring having pigtails at each end, and more particularly to a machine for efficiently forming the pig tails.In many instances, it is desirable to have reduced diameter ends or "pigtails" on a wound coil spring. One example application for such springs is in automotive suspension systems. A reduced diameter at one end of the spring can be beneficialfor efficiency in spring height and operating travel.In a typical coil spring forming manufacturing method, a cut-to-length bar is wound around a solid mandrel that sets the inside diameter of the coil spring. One end coil of the spring can be formed smaller than the next coil of the spring usingthis technique to provide a pigtailed spring. The mandrel for such springs typically has a smaller diameter on one end to form the reduced end of the spring.It is also beneficial in many circumstances to also reduce the diameter of the opposite end coil of the spring for similar size and performance reasons. A secondary pigtailing operation is performed after the mandrel has been removed. Typicallya separate pigtailing machine performs the pigtailing operation.Conventional pigtailing machines typically include an A head which receives the previously pigtailed coil and a B head which forms the second pigtail coil. Between the heads, are numerous adjustable fixtures, supports, and clamping arrangements. The adjustable components allow a pigtail of a desired shape to be formed onto an opposite end of coil springs of various sizes and shapes.Disadvantageously, setup for conventional pigtailing machines is quite extensive. Each adjustable component must be accurately and precisely aligned relative the heads. The setup time for each spring type increases the overall production cycletime and results in a lower manufacturing efficiency. Additionally, the adjustable components may shift over time due to the aggressive environment in which a pigtailing machine operates. Shift

1. Technical FieldThe present invention relates in general to an improved fencing tool and, in particular, to an improved system, method, and apparatus for bending both ends of wire fence mounting clips around fencing to secure the wire fence to a fence post.2. Description of the Related ArtFarmers and ranchers typically utilize metal fence posts to erect various types of metal fencing. Some of the more common types of metal fencing include single strand, woven wire, and barbed wire fences, and are hereinafter referred to as "wire"fences. Maintaining fences in good condition requires almost continuous inspection and repair. Livestock, wild life, and weather elements continually work to loosen and break down fences. Thus, many farmers and ranchers are required to inspect andrepair existing fences on a frequent basis.Wire fences are typically attached to a metal fence post by the use of wire mounting clips. Mounting clips are short, pre-formed or bent pieces of wire that are designed to initially fit loosely around a fence post and the wire fencing to besecured to the fence post. After the mounting clip is in position, it must be further deformed to retain the fence wire on the fence post. Each mounting clip has a V-shaped central portion that receives the fence post, and opposing curled ends thatpass around the fence wire on both sides of the fence post for fastening the fence wire to the fence post.Mounting clips may be used to either initially erect a fence or to repair a fence that requires mending. Farmers and ranchers typically use a pair of pliers, a screwdriver, or other common hand tools to install and/or remove the mounting clipsfrom the fence posts. However, using commonplace tools to tightly and securely fasten mounting clips to fence posts requires considerable effort. This is particularly true for the deformation of both sides of mounting clips.In the prior art, there have been a number of attempts to develop hand tools for attaching fencing

The present invention relates to a device or apparatus for securing the ends of a cable or wire tie device or the like. The present invention relates more particularly to a simplified hand-held cable tie securing apparatus.BACKGROUND OF THE INVENTIONCable or wire tie devices are generally known in the art, and typically comprise an elongated molded plastic strap having a head or locking end and an opposite, tail or free end. The free end of the elongated strap is for sliding through anopening in the head end, with a pawl arrangement for engaging a succession of serrated teeth formed along the length of the free end of the strap to accommodate unidirectional engagement which prevents strap withdrawal through the head end opening. Withthis construction, the free end of the strap can be wrapped about one or more elongated components such as a plurality of conductive wires, tubes or the like, and then drawn through the head end opening for securely retaining the components.It is known in the prior art to provide installation tools for cable or wire tie devices. These tools assist in feeding the free end of a cable tie through its associated head or locking end and cinch the closed loop cable tie around the desiredbundle, object or the like. For an example of a typical prior art installation tool see U.S. Pat. No. 6,497,258. Some of the problems associated with existing installation tools are that they are large, complex in construction, not portable, andexpensive to manufacture. Most of these installation tools are motor-driven and thus are not made for manual use Also, these existing installation tools are not readily adapted for use in the field. Moreover, there is a need in the art to provide aninstallation tool for use in space-restricted areas. This would be particularly advantageous where using both hands to fasten the cable or wire tie device is not feasible.Accordingly, it is an object of the present invention to provide an improved wire or cable tie

Each mounting clip has a V-shaped central portion that receives the fence post, and opposing curledends that pass around the fence wire on both sides of the fence post for fastening the fence wire to the fence post.Mounting clips may be used to either initially erect a fence or to repair a fence that requires mending. Farmers and ranchers typically use a pair of pliers, a screwdriver, or other common hand tools to install and/or remove the mounting clipsfrom the fence posts. However, using commonplace tools to tightly and securely fasten mounting clips to fence posts requires considerable effort. This is particularly true for the deformation of both sides of mounting clips.In the prior art, there have been a number

Cable Tie Tool Having Variable Trigger Linkage - Patent 7185680

Patents-433 — Mon, 04 Oct 2010 05:47:45 GMT

shared by: Patents-433 on: Monday, October 04, 2010

The present invention relates generally to a cable tie tool having a variable trigger linkage, and more specifically, to such a trigger linkage which may provide different tensioning forces to the tool head of the cable tie tool.Cable ties are used to bundle or secure a group of articles such as electrical wires or cables. Cable ties of conventional construction include a cable tie head and an elongate strap extending therefrom. The strap is wrapped around a bundle ofarticles and thereafter inserted through a passage in the head. The head of the cable tie typically supports a locking element which extends into the head passage allowing the strap to be inserted through the passage but preventing retraction of thestrap through the passage in the head. Two longitudinally separated portions of the strap are thereby secured to the head to define a loop for holding together the group of articles.In use, the installer manually places the tie about the articles to be bundled, inserts the strap through the head passage and then manually tightens the tie about the bundle. Further tightening of the cable tie, which increases the tension inthe strap thereof, may be provided by a cable tie tool.One type of such a cable tie tool includes a handle which is generally pistol-shaped and has a barrel into which the strap may be inserted for application of the tension thereto. The handle has a grip which depends from the barrel. The toolincludes a trigger mechanism a portion of which is supported within a trigger housing located under the barrel and in front of the grip. The trigger housing is elongate and in generally depending relation relative to the barrel such that, when the heelof the hand of a user is placed against the grip such that the fingers of the hand of the user extend forwardly, the fingers may encircle the forward surface of the trigger housing. Forcibly drawing the fingers toward the heel of the hand, such as bysqueezing the trigger housing and grip, causes t

Motor-driven Reinforcing Rod Binding Machine - Patent 7353846

Patents-433 — Mon, 04 Oct 2010 00:17:31 GMT

shared by: Patents-433 on: Monday, October 04, 2010

This invention relates to a motor-driven reinforcing bar binder, and more particularly to a cooling device for the reinforcing bar binder having a temperature control function.BACKGROUND ARTThere is previously known motor-driven reinforcing bar binders which are provided with a binding wire feeding mechanism for feeding a binding wire being bent in a loop shape to be wound over a reinforcing bar and a binding wire twisting mechanismfor twist and binding the binding wire wound around the reinforcing bar, wherein a binding wire feeding operation and a binding wire twisting operation are successively performed by a trigger operation to perform a once-cycle binding operation (see, e.g.JP-U-05-003494 and JP-A-2003-064876). These reinforcing bar binders include a single-motor type in which the binding wire feeding mechanism and the binding wire twisting mechanism are driven by a single motor and a two-motor type in which the bindingwire feeding mechanism and the binding wire twisting mechanism are driven by different motors, respectively. However, in either type, the operation of twisting the binding wire is subjected to considerable load and the motor in charge of the twistingoperation generates a large quantity of heat.As a means for dissipating the heat generated by an electric tool, there is a previously known method in which the interior of a housing inclusive of the motor is cooled during motor rotation by a wind supplied by a fan attached to a motor shaft(see, e.g. JP-U-07-007805). However, in the reinforcing bar binder, in which the operation pattern of the motor is different from that of the electric tool such as an electric drill or an electric driver, a sufficient motor cooling effect cannot beobtained by the fan which rotates simultaneously with the motor. Therefore, the reinforcing bar binders have not been specially provided with cooling means such as fans.The operation pattern of the reinforcing bar binder is a short-time high speed operation in which t

Reduced Force Sealless Connection Mechanism - Patent 7350543

Patents-433 — Sun, 03 Oct 2010 09:18:15 GMT

shared by: Patents-433 on: Sunday, October 03, 2010

The present invention pertains to a sealless connection mechanism for joining strapping materials. In particular, the present invention pertains to a reduced force sealless connection mechanism for use in a strapping machine to create a seallessconnection between overlapping strapping materials.Strapping machines (or "strappers") are well known in the art. These machines are used for strapping articles, e.g., a load, together with strapping material. Strapping material is offered in a variety of sizes and materials and is generallystored on a roll. Conventional strapping materials include steel and plastic.Typically, a free end of strapping material is passed around the load until there is an overlap between the free end and the strapping material still connected to the roll. The overlapping portion of strapping material is placed between jaws ofa strapping machine and the free end of the strapping material is fixed in place by a gripper portion of the machine. After the strapping material is fixed, the material is tightened or tensioned around the load to a desired tension. This isaccomplished by operating a feed wheel, a windlass or similar mechanism to pull back, or tension, the strapping material.A typical strapper includes sealing heads for sealing the free end of the strapping material onto itself, around the load. Typically, in manual (i.e., hand-operated) strappers, a handle is rotated which applies a force to cause a punch orsealing head to press down against the strap to seal the strap to itself. After the strapping material is sealed, the strapping material still connected to the roll is cut by a cutter, which is a portion of the strapper. This completes one strappingoperation. This type of seal, known as a "sealless" connection, is effected by sealing the strap to itself, and differs form those strappers that position a separate piece of material around the tensioned strap.Typically, such a sealless connection employs one or two longitudinal r

The present invention relates to an installation tool, and more particularly, to an installation tool having an adjustable handle and an improved tensioning mechanism for controlling the tension in metal ties or metal strapping installed around abundle.BACKGROUND OF THE INVENTIONAs is well known to those skilled in the art, cable ties, or straps are used to bundle or secure a group of articles such as electrical wires and cables. Cable ties of conventional construction include a cable tie head and an elongated tailextending therefrom. The tail is wrapped around a bundle of articles and thereafter inserted through the passage in the head. The head of the cable tie typically supports a locking element which extends into the head passage and engages the body of thetail to secure the tail to the head.In practice, the installer manually places the tie about the articles to be bundled, inserts the tail through the head passage and then manually tightens the tie about the bundle. At this point, a cable tie installation tool is used to tensionthe tie to a predetermined tension. The tools of the prior art, although capable of tensioning and thereafter severing the excess portion of the cable tie, typically have several disadvantages therewith.It is therefore an object of the present invention to provide an installation tool with an improved tensioning mechanism.It is another object of the present invention to provide an installation tool with an improved resistance mechanism that overrides the preset tension to provide variation in the tension applied to the tie or strap.It is another object of the present invention to provide an installation tool with a handle that is easy to adjust.SUMMARY OF THE INVENTIONThe present invention is direct to an installation tool used to install a bundling member, for example a metal tie or strap, around a bundle of objects. The installation tool includes a tool body, a front handle and a rear handle. The fronthandle is positioned with

Method For Increasing The Torque Of A Pre-tensioned Spring That Is Wound Around A Rotating Body Comprising A Longitudinal Axis - Patent 7267142

Patents-433 — Sat, 02 Oct 2010 19:50:00 GMT

shared by: Patents-433 on: Saturday, October 02, 2010

This application is a 35 USC 371 of PCT/EP04/52473, filed Oct. 7, 2004BACKGROUND OF THE INVENTIONThe invention relates to a method for increasing the torque of a pretensioned spring which is arranged around a rotary body having a longitudinal axis and to a use of the method. Methods for the increase of torques of pretensioned springs areknown. In this context, for example, there is provision for arranging the pretensioned spring around a rotatable shaft. Both ends of the pretensioned spring are in this case fixed to stops which belong to the rotatable shaft. It is often desirable, inthese circumstances, for the pretensioned spring mounted in this way to be rotated over a first angular travel without the action of force. After a maximum of one full revolution of the rotatable shaft, one end of the spring is brought onto a stopwhich, as a rule, is to be assigned to a housing part. When the rotational movement is subsequently continued, an increase in the torque occurs due to the action of a force which is higher than the pretensioning force of the spring. This method has thedisadvantage, however, that the pretensioned spring can execute only at most one full revolution without the additional action of force, before an increase in the torque then occurs. In the art, however, it is often desirable for the pretensioned springto complete a plurality of full revolutions before an increase in the torque occurs. It is not possible, however, to fulfill these desires by means of the known devices.SUMMARY OF THE INVENTIONThe object on which the invention is based is, therefore, to provide a method for increasing the torque of a pretensioned spring which is arranged around a rotary body having a longitudinal axis, in which it is possible to initiate the increasein the torque only after a plurality of revolutions of the pretensioned spring without the additional action of force. The object of the invention is, furthermore, to provide a use of the method for increasing

Wire Wrapping Hand Tool - Patent 7261128

Patents-433 — Sat, 02 Oct 2010 05:15:06 GMT

shared by: Patents-433 on: Saturday, October 02, 2010

This invention relates to a wire wrapping hand tool, and in particular to a tool adapted for hand-operation for wrapping or unwrapping wires around electrical terminals.BACKGROUND OF THE INVENTIONWire wrapping tools are well known in the art and are commonly used nowadays for the making of connections to terminals on a printed circuit board (PCB). See, for example, U.S. Pat. Nos. 4,177,555, 4,194,700, and 4,620,574, whose contents areherein incorporated by reference, as examples of such tools. The wrapping tool wraps the wire around a sharp-cornered terminal which crushes any oxide layer between the terminal and wire and provides a tightly-held oxide-free metal-to-metal contact ofthe wire to the terminal. When the tool is reverse driven, with a different active bit, it can be used to unwrap the wire from the terminal. The typical tool is a wire-wrapping gun containing what is known as a removable bit and sleeve. The latter istypically fixed, and the bit rotates, usually clockwise (CW), within the sleeve. Wire from a spool, for example, is fed through the sleeve to the bit face. The bit has a bore for receiving the terminal, and when the bit is rotated around the terminal,structure on the bit face grabs the wire and wraps it around the terminal. The bit and sleeve are replaceably held on the tool by a front-facing collet or chuck at the distal end of the tool (locations on the tool are with respect to the handle end)which when tightened holds the sleeve within the tool. The bit is held in place within the sleeve by a shoulder on the bit. Replacement of the bit and sleeve is accomplished by loosening of the collet to release the bit and sleeve so it can be removedand replaced. Reasons for replacing include wrapping on a different size of terminal.So far as we know, all current tools suffer from the problem of possible electrical shocks to the tool user should the terminal be electrically active and the user contacts any metal screws on the tool, or the m

Method Of Forming A Loop In A Wire - Patent 7343939

Patents-433 — Sat, 02 Oct 2010 04:41:34 GMT

shared by: Patents-433 on: Saturday, October 02, 2010

The present invention relates to the field of hand tools for forming wire and the like, more particularly, to a method of using a pliers for forming wire into loops and similar shapes.In the past, wire loops have been formed using conventional longnose pliers, resulting in imperfect loops. Round nose pliers have permitted formation of more circular loops, but did not assure that repeated use would result in identical sizedloops, because of the tapered jaws of the pliers.Other specialty pliers are known for forming wires into loops, commonly known as wire wrapping pliers, which have one jaw formed in a series of stepped diameter cylinders, and the other jaw being flat or concave where it faces the cylindricaljaw. Such wire wrapping pliers were not convenient to forming tight loops because the wire was gripped between the jaws at a location which was typically 180 degrees away from the closure of the loop. Forming the loop adjacent the contact between thejaws of such pliers exposes the wire to the edge of the flat or concave jaw, reintroducing the possibility of undesired deformation of the wire resulting from contact with such edge.The present invention overcomes the shortcomings of the prior art by using a pliers-type wire forming tool in an easy and convenient method to form consistently-sized wire loops, with or without a coil adjacent the loop.BRIEF SUMMARY OF THE INVENTIONIn one aspect, the present invention includes a method for forming a loop in a wire forming a U-shape in a wire, placing the U-shape between a pair of jaws in a pliers of the type having opposing faces on respective distal ends of a pair of jaws,with each jaw having a relief between the face and a pivot point of the pliers, the reliefs forming a recess, such that the U-shape extends around a post located in the recess, closing the jaws against the wire such that the faces compress the U-shapeinto a loop surrounding the post; and removing the wire loop from the pliers.The method may further i

1. Field of the InventionThe present invention relates to a wire comb and method for assembling an organized bundle from a plurality of strands, such as wires or cables, and more specifically, to a wire comb that can be applied to strands for combing at any pointlengthwise.2. Background of the Related ArtIn the related art, several methods and devices, such as wire combs, exist for the purpose of assembling an organized bundle from a plurality of strands. U.S. Patent Application Publication No. US 2002/0104577 A1 (hereafter "McGroarty"), alsopublished as International Publication Number WO 02/062505 A1, discloses a related art wire comb that permits combing and straightening of wires or cables for CAT-5 cables. As illustrated in FIG. 1 of McGroarty, a plurality of holes 25-32 are sized toreceive a separate wire or cable. These separate wires or cables are threaded through each of the holes 25-32 from their respective first ends. The bundle of wires or cables are then combed lengthwise from the first ends to the second ends, so that allwires are located at the same relative position with respect to one another along the entire length of the cable bundle.However, the related art wire comb of McGroarty has various problems and disadvantages. For example, because McGroarty uses holes, the wires or cables can only be bundled from one end to an opposite end. As a result, the entire cable bundlemust be combed at once, as segments cannot be separately combed.Another method of bundling strands, such as cables, is for a technician to dress the cables by hand. This allows for only a portion of the length of the cable to be bundled, but requires significant time and effort on the part of the technician.SUMMARY OF THE INVENTIONIt is an aspect of the present invention to overcome at least the above-described problems and disadvantages in the related art by providing a wire comb apparatus for assembling an organized bundle from a plurality of strands that can be appliedt

Particularly, the invention relates to a binding line clamp apparatus of a reinforcing bar binder constituted to graspan end portion of a binding line to twist, a reinforcing bar binder constituted to pertinently control a length of a binding line in accordance with a reinforcing bar diameter and a reinforcing bar binder reducing an amount of consuming a binding line.BACKGROUND ARTA reinforcing bar binder is comprising a binding line feed mechanism for feeding out a binding line of a wire or the like wound around a reel to be wound around a reinforcing bar, and a binding line twist mechanism for twisting the binding linewound around the reinforcing bar to bind, and the binding line feed mechanism and the binding line twist mechanism are successively operated by trigger operation to carry out binding operation of 1 cycle.When a circular arc shape nose of the reinforcing bar binder is hung around the reinforcing bar and a trigger lever is pulled, the binding line is fed out around an inner peripheral face of a nose by the binding line feed mechanism to form abiding line loop at a surrounding of the reinforcing bar, a rear end of the binding line loop is cut by a cutter mechanism, a pair of hook type hooks of the binding line twist mechanism are closed to grasp the binding line loop to thereafter rotate andthe binding line loop is twisted to bind the reinforcing bar.The reinforcing bar binder of a prior art is constituted to turn the binding line around the reinforcing bar by two rotations or more and catch a middle portion of the binding line loop remote from a front end and a rear end thereof by the pairof hooks and this is because when portions of the binding line at a vicinity of the front end or the rear end is caught, in rotating the hooks, the front end or the rear end is drawn out from the hooks to disengage the loop and binding cannot

Method For Removing Wires Or Tapes From Pressed Bales Of Raw Material And Wire Coiling Device For Carrying Out The Method - Patent 7152634

Patents-433 — Fri, 01 Oct 2010 12:15:16 GMT

shared by: Patents-433 on: Friday, October 01, 2010

1. Field of the InventionThe invention relates to a method for removing wires or tapes from pressed bales of raw material, in which the wires or tapes are applied so that they form at least one each point of intersection on at least two opposite bale sides, and to a wirecoiling device for removing wires or tapes from pressed bales of raw material.2. Discussion of Background InformationMethods and devices of this type are used, e.g., in the paper industry. Often the raw material for paper production, i.e., cellulose or recovered paper, is namely supplied in pressed bales that are held together by wires or tapes. Such wires ortapes usually have to be removed before the raw materials are then processed into an aqueous suspension, e.g., in a pulper. Although this can also be done manually, it is dangerous and complicated. Methods of the type mentioned here have therefore beendeveloped, with the aid of which the removal of wires and tapes can take place automatically. Coiling devices that can be used for such methods are known, e.g., from DE 28 21 336 C2. An important requirement of such methods is a cycle rate being ashigh as possible for the unwiring, i.e., that as many bales as possible should be processed, e.g., per hour. The unwiring station with a plurality of devices is very expensive, so it should be used in an optimal manner.SUMMARY OF THE INVENTIONThe present invention improves the methods of the type mentioned such that the removal of wires or tapes from paper or cellulose bales can be made even quicker.According to the invention, the method includes bringing the bales into an unwiring position via a bale positioning device, determining a position of the wires automatically with a wire finder and positioning a wire coiling device over the wire,severing the wires or tapes, and removing the wires or tapes from the bale by at least one wire coiling device. The position of the point of intersection is automatically determined on at least one bale side an

The present invention relates to a technique for assembling motor stators. More particularly, the present invention relates to a method and apparatus for insertion of coil windings into a stator.Electric motors of various types are commonly found in industrial, commercial and consumer settings. In industry, such motors are employed to drive various kinds of machinery, such as pumps, HVAC systems, conveyors, chillers, compressors, fansand so forth, to mention only a few. Conventional alternating current electric (ac) motors may be constructed for single or multiple phase power, and are typically designed to operate at predetermined synchronous speeds, such as 3600 rpm, 1800 rpm, 1200rpm, and so on. Such motors generally include a stator, comprising a multiplicity of coils, surrounding a rotor, which is supported by bearings for rotation in the motor housing or compartment. In the case of ac motors, ac power applied to the motorcreates magnetic excitation causing the rotor to rotate within the stator. The speed of this rotation is typically a function of the frequency of the applied ac input power (i.e., frequency) and of the motor design (i.e., the number of poles defined bythe stator windings). A rotor shaft extending through the motor housing takes advantage of this produced rotation and translates the rotor's movement into a driving force for a given piece of machinery. That is, rotation of the shaft drives the machineto which it is coupled. The driving force is typically expressed as a horsepower (HP) or kilowatt (kW) rating, and is a function of the active material employed in the motor design.Traditionally, the construction of large commercial ac motors is a labor-intensive, manual process. More specifically, the formation, insertion, and arrangement of coil windings with respect to the stator may be an arduous process. Typically,coil windings are formed by feeding conductive wire onto or about a rotating winding form, which loops the wire around wir

Device For Reforming Socket Contacts - Patent 7243688

Patents-433 — Thu, 30 Sep 2010 18:11:24 GMT

shared by: Patents-433 on: Thursday, September 30, 2010

& BACKGROUNDEmbodiments of the present invention are related to the field of electronics; and in particular, to the reformation of socket contacts of electronic apparatuses.Modern electronic apparatuses often employ sockets having contacts disposed therein at predetermined positions. Further, the contact surfaces often have desired shapes or profiles. With modern surface mounted metallic spring contact sockets,e.g. Land Grid Array sockets, the contacts are often made of relatively thin materials, and therefore, relatively fragile. As a result, there is a significant probability that mechanical damage and deformation could occur, e.g. during system integrationassembly.Currently there are no devices designed for reforming damaged socket contacts (restoring their shapes/profiles), such as surface mounted metallic spring contact sockets, especially not in a repeatable manner. Under the present state of the art,damaged contacts, such as bent contacts, are often reformed using ad-hoc devices, such as tweezers. However, the ability to restore the shape/profile of a damaged contact to its original position and/or shape/profile using an ad-hoc device, such as apair of tweezers, is limited. The options to successfully rework damaged contacts at the system level or in the field are often limited to replacement of the motherboard, or thermally unmounting and remounting another socket using surface mounttechniques. BRIEF DESCRIPTION OF THE DRAWINGSEmbodiments of the present invention will be described referencing the accompanying drawings in which like references denote similar elements, and in which:FIG. 1 illustrates a cross-sectional view of an apparatus with formation tips adapted to impart profiles to surfaces of a socket contact, with the apparatus in an unengaged position, in accordance with one embodiment;FIG. 2 illustrates another cross-sectional view of the apparatus of FIG. 1, with the apparatus in an engaged position;FIG. 3 illustrates a cross-sectional view o

Further, as disclosed in, for example, JP-A-08-034406(claim 2, paragraph No. 0022, paragraph No. 0055), there is proposed a reinforcing bar binding machine for pulling back a binding wire after binding wire feed operation, bringing a loop of the binding wire into close contact with a reinforcing bar tostart twisting operation. According to the reinforcing bar binding machine, by pulling back the binding wire, a line length thereof is adjusted in accordance with a diameter of the reinforcing bar to thereby promote finishing and also save to reduce anamount of consuming the binding wire.In the case of constituting the reinforcing bar binding machine such that the binding wire is pulled back after the binding wire feeding operation and the twisting operation is started in a state of bringing the binding wire into close contactwith the reinforcing bar, setting of a pull back tension poses a problem. When a feeding force of the binding line feed mechanism is weak, time is taken in pulling back the binding wire or the binding wire cannot be pulled back. Further, when thefeeding force is conversely excessively large, there is a concern of cutting the binding line.As a means for preventing such a drawback from being brought about, it is conceivable to provide electric co

shared by: Patents-433 on: Wednesday, September 29, 2010

The present invention relates generally to a tension and anti-recoil mechanism for a cable tie tool, and more specifically, to such a mechanism for limiting the tension applied to the cable tie by the tool and limiting the re-coil of the toolwhen the cable tie is cut.Cable ties are used to bundle or secure a group of articles such as electrical wires or cables. Cable ties of conventional construction include a cable tie head and an elongate strap extending therefrom. The strap is wrapped around a bundle ofarticles and thereafter inserted through a passage in the head. The head of the cable tie typically supports a locking element which extends into the head passage allowing the strap to be inserted through the passage but preventing retraction of thestrap through the passage in the head. Two longitudinally separated portions of the strap are thereby secured to the head to define a loop for holding together the group of articles.In use, the installer manually places the tie about the articles to be bundled, inserts the strap through the head passage and then manually tightens the tie about the bundle. Further tightening of the cable tie, which increases the tension inthe strap thereof, may be provided by a cable tie tool.One type of such a cable tie tool includes a housing which is generally pistol-shaped where the housing has a barrel into which the strap may be inserted for application of the tension. The housing has a grip which depends from the barrel. Thecable tie tool may have a mechanism for limiting the tension force which is applied to the strap of the cable tie and for cutting the strap of the cable tie when the maximum tension is applied to the strap. Such cutting of the strap may resulting are-coil force being applied to the hand of the user. The magnitude of this re-coil force may be limited by a mechanism in the cable tie tool. Such a mechanism for limiting the tension force applied to the strap of the cable tie and for limiting there-coil for

This invention relates to an instrument for applying a tie to two items and method of making same. More particularly, it relates to an instrument and the method wherein atie is pulled for drawing the two items together, and the tie is then fixedly twisted onto itself for securing it to the items. This instrument is thus utilized in helically twisting a tie, wire, suture, or the like onto itself after the tie is securedto the item to be tied.For further reference, our U.S. patent application Ser. No. 10/158,470, filed May 31, 2002, and now U.S. Pat. No. 6,752,810, issued Jun. 22, 2004 can be considered.BACKGROUND OF THE INVENTIONThere are many conditions where a tie, such as a wire, suture, cable, or like strand capable of being secured onto itself by twisting, is required to hold items together. One such condition is in the medical field where a patient's sternum hasbeen separated for heart surgery and it is then necessary to pull the separated parts of the sternum together and to then twist sutures onto the sternum to hold the sternum together for natural healing by knitting. The present invention is particularlyuseful in the medical field under conditions where any bone is separated, and it will be basically described in that context. Of course, it will also be disclosed for and cover applications in any field where a tie is to twisted onto itself forsecurement.Thus, the present invention provides and instrument, and method of making same, wherein a tie or suture can be readily and accurately installed on items or bone and then tensioned to draw the items or broken bones together and to ultimately twistthe tie or suture onto itself in a helical pattern to tie the items or bones together. The twisting is accomplished by progressively twisting along the tie in even knots and without the incidence of breaking the tie during twisting.With this invention, the items or bones are drawn together and the tie or suture is then twisted onto itself. Thus, there is

shared by: Patents-433 on: Wednesday, September 29, 2010

The invention relates to a punching/deforming tool for a strapping unit for producing an auxiliary-freeconnection of ends of a strapping band, the tool having a recess of different widths, and at least one section of the recess-bounding wall being provided with a rounded portion in the region of at least one change in width. The invention additionallyrelates to a process for producing such a tool, and to the closure itself.Strapping units by means of which a tensioned band loop can be positioned around articles which are to be packaged have been known for some time now. This takes place, in particular, for packaging and transporting purposes. Strapping units withvery different functional principles, in particular, in relation to the connection of the two band ends, have become known in this context. The present invention relates to strapping units in the case of which the band loop is closed by deformation andthe production of an incisions. A form fit is formed between the two band ends in this case. In the case of strapping units of the generic type, furthermore, the closure is produced by two interacting tools of the strapping unit. The tools are fedonto the top side of the two bands, one tool from the side of one band and the other tool from the side of the other band. The two tools, usually referred to as punch and die, force the band ends, located one upon the other, into a cavity of the die,the deformation taking place as a result.It is known from the prior art that the recess of the die has its largest extent in the band-running direction, the width of the recess usually changing a number of times in the longitudinal direction of the recess. The die is thus of acomplicated shape which is optimized in respect of the incisions which are to be achieved. It is usually sought to achieve the sharpest possible edges and corners in the wall, the intention being for these to make it possible for the two band ends tointerlock to particularly good effect.

FIELD OF THEINVENTIONThe present invention relates generally to a former for a cage-making machine which is adapted to hold a plurality of longitudinally extending rods and, in particular, to a former which is adapted to hold a plurality of longitudinally extendingreinforcing rods.The invention has been developed primarily for use with cage-making machines which are adapted for use in the construction of reinforcing cages for reinforcing concrete and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular use.DESCRIPTION OF THE PRIOR ARTSome cage-making machines which are adapted for constructing reinforcing cages for reinforcing concrete utilise a former which is mounted on the machine. The former is adapted to hold a plurality of longitudinally extending reinforcing rodsduring the construction of a reinforcing cage. In particular, the former is adapted to hold the rods such that the rods are maintained in a particular transverse relationship with respect to each other. Cage-making machines which employ formers of thistype are usually operated by firstly inserting a plurality of longitudinally extending reinforcing rods into the former. The rods are then progressively withdrawn from the former as a reinforcing cage is constructed. Construction of the cage typicallyinvolves winding a reinforcing bar around the withdrawn portions of the rods while simultaneously welding or otherwise attaching the bar to the rods.A reinforcing cage manufacturer will usually have a number of formers on-hand with each former being adapted for use in the construction of a reinforcing cage having a particular arrangement of longitudinally extending reinforcing rods. Thereare a number of significant disadvantages associated with formers of this type.One disadvantage is that, since cage-making machines usually permit only one former to be mounted thereon, it is often necessary to provide a s

Patents-433 — Wed, 29 Sep 2010 03:12:00 GMT

shared by: Patents-433 on: Wednesday, September 29, 2010

The present invention relates generally to tools for installing cable ties and, more particularly, to handheld pneumatic tools that provide tension to the cable ties and cut off excess portions of the ties while under tension.Flexible cable ties and tools for installing flexible cable ties are well known. Cable ties are used to bundle and secure wires, cables, and tubes, and similar items. As an example, cable ties may be used on an automobile assembly line tosecure fluid and electrical lines to a vehicles chassis. Generally, installation tools are designed so that the cable ties will bundle such items in a tight, secure bundle. Typically, flexible cable ties include a head portion and a tail portionextending from the head. The tail is looped around the items to be secured and passed through the head portion. A locking or ratcheting mechanism in the head holds the tail in place and secures the tie around the bundled items. Once a predeterminedtension has been reached, the excess portion of the tie is clipped near the head portion.A variety of tools have been developed to enable workers to install flexible cable ties quickly, efficiently, and uniformly. These tools generally grip the tail portion of the tie after the tie has been looped around a bundle and the tail ispassed through the head portion of the tie. The tool uses a pawl or similar device to grip and tension the tie to a predetermined tension, and a blade will sever the excess portion of the tail, thereby providing a tidy bundle of items.Specifically, various handheld tools have been developed to assist in the installation of cable ties. Commonly, these devices have a pistol or gun-like shape, with a squeezable trigger that allows the tail to be pulled until a predeterminedtension is achieved, after which a cutting blade adjacent the nose of the tool cuts off the excess portion of the tie. An example of such a tool may be found in Dyer et al., U.S. Pat. No. 5,921,290. The tension at which cuto

SNone.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTNot Applicable.APPENDIXNot Applicable.BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention is in the field of binding and baling operations, more particularly in the field of wire knotting.2. Related ArtIn the field of binding and baling bulk material items such as cotton with wire, a variety of mechanical wire knotters are known in the art. These knotters work in conjunction with a baling equipment bed through a variety of techniques wraps alength of wire around a volume of bulk material to be baled and delivers a leading end of each individual wire proximate to a trailing end, the same wire, which has been cut by the baling machine. These wire ends are then acted upon by wire knotters tosecure them so that they will retain the bulk material bale in a compressed volume after the baling machine releases the bale.Knotting is typically achieved by twisting the two wire ends around one another. To do so, the wire ends are captured together in a slot or groove and then a gear wheel pinion or the like rotates in order to twist them together. After thetwisting operation is complete, the separate mechanical component pushes the knotted wires out of the groove because the overall knotting apparatus is generally configured around a rotating drive shaft which delivers a rotational energy through a seriesof gears to the actual knotting linkage, it is advantageous for the ejector mechanism to also be actuated by a rotational device.Hence in the prior art, ejector drive hubs were designed. These hubs had capacity to be driven by the overall drive shaft, typically by a boss detent. They also had a capacity to be held stationary while the drive shaft and other machineryrotated during knotting, typically by a latch and notch arrangement. Finally, the ejector drive had an extension boss or the like mentioned in position to engage corresponding boss or extension on an ejector in order t

shared by: Patents-433 on: Tuesday, September 28, 2010

The present invention relates to a crimping tool for providing a metal crimp seal on plastic strapping. More particularly, the present invention relates to a side action crimping tool for sealing a metal crimp seal to plastic strapping thatreduces the opportunity for damage to the plastic strap material.Strapping material is used in wide variety of applications to secure or bundle loads. The strap material is typically metal or plastic and can be applied to the load using either a manual sealer or a powered sealer. Powered sealers can bepneumatic or electric and can be hand-held or machine-frame type machines. Non-powered (manual) sealers are typically hand-held or hand-operated tools.The seals (for both metal and plastic strap) can be of the seal-less type or of the crimp seal type. In a seal-less seal or joint, the material is welded to itself (if plastic) or mechanically joined as by locking cuts and projections. Crimpseals, on the other hand, use a band that is bent or wrapped around overlapping portions of strap and mechanically crimped onto the strap. In such a joint, the seal is compressed onto the strap material and the strap material is deformed so as to besecured in the seal. Generally, the inside of the seal is coated with grit to increase the friction between the seal and the strap.In many such seals, the seal is cut, at least in part and is urged into the material to create an interference type of fit. In this manner, portions of the strap and portions of the seal are forced from their respective bodies, into the othermaterial. That is, the strap and seal are cut and bent into each other so that the materials are not only held by compression, but also by interference of the crimp seal with the strap "pulling" from the seal. While such an arrangement is acceptablefor metal strapping material it is unacceptable for plastic strap in that the integrity of the plastic strap can be compromised by cutting the strap material.To this end, crimp seal a

shared by: Patents-433 on: Monday, September 27, 2010

1. Field of the InventionThe invention relates generally to the field of wirework, and more specifically, to tools for untwisting wires.2. Description of Related ArtPairs of metal wires are often twisted together into a helical configuration. This sort of twisting can be used to join wires over long lengths, and has certain other uses and advantages. For example, when wires are used to carry electricalsignals, helical twisting of pairs of wires reduces electromagnetic interference with the signals that the two wires are carrying.Cables using metal wires for signal conduction are in wide and common use. One of the more common cables in use today is the standard Category-5 (CAT-5) Ethernet cable, which is used to connect computers and other computing hardware fornetworking purposes. Inside the CAT-5 Ethernet cable are four twisted pairs of wires, for a total of eight conductor wires. The ends of the cable may be capped with standard RJ-45 connectors, or the wires may simply be connected to appropriate terminalblocks without a connector, depending on the application.When installing or otherwise manipulating cables that use twisted pair wires, it is often necessary to untwist the individual wires so that they can be fitted into connectors or terminal blocks. For example, to insert the end of the CAT-5Ethernet cable into a connector, the four pairs of wires are untwisted a short distance, and the connector is crimped over the untwisted, straightened ends. An electrical connection is made by contacts within the connector that penetrate the insulationof the individual wires.Ethernet cable is often installed in large volumes, for example, in a new office building. A large spool of the cable is usually brought in, and installers are left to cut whatever lengths of cable are necessary from the spool. In order toconnect those pieces of cable, a short length of the twisted pairs of wires is untwisted, as was described above. The process of untwisting the pairs of wi

This invention relates generally to the assembly of coil springs of the type used in bedding and upholstery and, more particularly, to an improved machine for fabricating coil spring assemblies.BACKGROUND OF THE INVENTIONIt is well known to fabricate a coil spring assembly from a plurality of coil springs organized in matrix-like fashion into columns and rows. Often the coil spring rows are interconnected in both the top and bottom planes of the assembly. Therows and columns of the matrix are held in spatial relation in the finished assembly by some type of fastener or tie, for example, a lacing wire, that interconnects adjacent springs throughout the matrix one with the other. The helical lacing wireextends from one edge to the opposite edge of the spring assembly between adjacent rows of that assembly. The lacing wire connects adjacent springs within adjacent rows simply by being wound around the juxtaposed lacing legs or end turns of the adjacentsprings. After fabrication of the coil spring assembly, manufacture of a finished product is completed by placing a cushion or pad of material, e.g., woven or non-woven batting, foam rubber, or the like, over the top and/or bottom surface of the springassembly matrix so formed, and then enclosing that structure with an upholstered fabric or cloth sheath or the like to provide a finished saleable product. One basic use of such coil spring assemblies is in the bedding industry where those assembliesfind use as mattresses or box springs, but other uses are in the home finishing industry where the finished coil spring assembly may be used in a chair's seat or a chair's backrest or the like.An automatic machine for assembling continuous coil spring rows is also known. Such a machine initially picks up a row of coil springs by inserting pickup blades within the spring's barrel and moving the spring through a 90.degree. arc onto asupport surface. The row of springs is then compressed against the support surface, and the

The invention relates to a strapping unit for wrapping a tightening strap around a packaged item.BACKGROUND OF THE INVENTIONSuch a strapping unit has a base plate which is provided with a supporting surface for arranging on a packaged item, the strapping unit furthermore has a tensioning device with which a strap tension can be applied to the tightening strap, forwhich purpose the tensioning device is provided with an actuable tensioning tool which can be brought into contact with the strap, the tensioning tool being fastened releasably to the strapping unit by at least one fastening means, also has a sealingdevice, which sealing device is provided with a single- or multi-part sealing tool with which two strap layers can be connected permanently to each other by contact with the strap, the sealing tool being fitted on the strapping unit by at least onereleasable, further fastening means, the strapping unit is furthermore provided with a separating means with which the strap can be severed, for which purpose the separating means has a blade which can be brought into contact with the strap, at leastpart of the separating means being fitted releasably on the strapping unit by at least one further, releasable fastening means.Strapping units of this type are frequently provided for mobile use so that a user can wrap a steel strap around a packaged item in any desired location. A first generic type of these strapping units typically has a sealing device which producesa connection of two layers of the steel strap by means of multiple notchings, without using an additional sealing element, such as, for example a lead seal. For this type of strapping unit it is also typical for both the strap tension and the formationof a seal to be produced manually without the assistance of outside energy, in particular electric or pneumatic energy. For this purpose, the operator of a strapping unit according to the generic type has only to provide his own muscular power. However, the i

OF INVENTIONThe subject of the present invention is an appliance for the automatic fitting of twisted ties, for example for the attachment of vine shoots or of plant branches to supports, such as stakes or training wires.Each appliance may also be used for other applications, in particular industrial applications, requiring the tying of two pieces of small cross section, in particular of filamentary pieces.BACKGROUND OF INVENTIONIn the agricultural sector, it is often necessary to attach a plant to a support, in order to guide it as it grows. Thus, in particular, it is known to attach vine shoots, generally to hori ontal wires called training wires. If this operationis carried out manually, it is lengthy and difficult, since it is necessary to cut wire portions from a reel, surround the shoot to be attached and also the wire to which it is to be attached, and then perform the twisting of the loop thus formed inorder to ensure the closing of the latter.To facilitate and speed up this tying operation, it was envisaged to produce appliances ensuring automatic fitting, that is to say comprising a body equipped with means for the feeding of continuous wire, for delivering this wire to a curved jawcapable of being reclosed on itself so as to surround the article or the like around which the tie is to be twisted, the body being equipped with a twister driven in rotation during the twisting operation and with a device for cutting the wire in orderto form a tie. Such an appliance is described in the document FR 2 738 56. This appliance comprises a single motor ensuring the various functions of delivering the wire, of closing the jaw, of cutting a tie and of twisting the tie. However, themechanism employed is complex, and the power available for each operation is not always sufficient in view of the use of a single motor.SUMMARY OF THE INVENTIONThe invention provides an appliance for the automatic fitting of twisted ties, which possesses excellent reliability and a high

shared by: Patents-433 on: Saturday, September 25, 2010

This invention relates generally to the testing of semiconductor components, and more particularly to the testing and burning-in of semiconductor components contained on a substrate, such as a semiconductor wafer.BACKGROUND OF THE INVENTIONSemiconductor components such as semiconductor dice and packages are routinely tested during manufacture. Semiconductor dice, for example, are typically fabricated on a semiconductor wafer using well known processes such as doping, masking,etching, and deposition of metals. Following fabrication of the dice, the wafer is probed and mapped to test the gross functionality of each die. A wafer prober and probe card can be used to electrically engage bond pads, or other test pads on thedice, and to apply test signals to the integrated circuits contained on the dice. The non functional dice are mapped in software or mechanically marked.Following wafer probe, the functional dice can be singulated and packaged, or alternately retained in unpackaged form as known good die (KGD). Packaged dice are then burn-in tested by heating the dice while electrically biasing the integratedcircuits on the dice. Bare dice can be burn-in tested using temporary carriers configured to temporarily package the dice. Burn-in boards are adapted to hold a large number of semiconductor packages, or temporary carriers for bare dice, in a chamberwith temperature cycling capability. The burn-in boards are also in electrical communication with test circuitry configured to generate and to apply test signals to the dice.In addition to burn-in testing, full functionality test can be performed on the packaged or bare dice to evaluate various electrical characteristics of the integrated circuits. Among the parameters that can be tested are input and outputvoltages, capacitance, pad leakage and current specifications. Memory devices can also be subjected to logic tests wherein data storage, retrieval capabilities, and response times are measured.Recently, differ

Field of the InventionThe present invention relates to a tool and process of using the tool for guiding cables and, more particularly, to guides and tools for organizing and identifying a plurality of telecommunications cables during network cable installation.2. Description of Related ArtAt the present time during network cable installation, sets of up to twelve telecommunications cables at a time are pulled through the walls, ceilings or floors of buildings to a communications room where the sets of cables are terminated onpatch panels located on equipment racks. Typically 16, 24, 32, 48 or 96 port patch panels are used. Each equipment rack may have multiple patch panels, and a large number of wires or cables are often terminated each of these patch panels. Duringinstallation these cables easily become tangled and disorganized. Tangled cables make it difficult for installers to identify cables. Tangling also makes it difficult for any future identification, replacement or repair of the cables after thecompletion of network cable installation.Several devices and methods are available for organizing telecommunications cables. Many of these are permanent fixtures that attach to equipment racks, which only organize the cables once they have entered the equipment rack. An example ofsuch a device and method of using such device is shown in U.S. Pat. No. 6,540,312. Unfortunately, the cables remain entangled from the point of emersion into the communications room to the equipment rack. It would be preferable if organizationoccurred from the point of emersion into the communications room to the patch panel.Another problem with the current technology is relate

FEDERALLY SPONSORED RESEARCHNot ApplicableSEQUENCE LISTING OR PROGRAMNot ApplicableBACKGROUND OF THE INVENTIONField of InventionThis invention relates to tie wire used for the stabilization in masonry construction, specifically for the use of bending support wire: Ladder Tie Wire, Rectangular Tie Wire, Truss Tie Wire and the Z Tie Wire.BACKGROUND OF THE INVENTIONPrior ArtThe closest prior art of which we are aware of in the same physical aspect is the "Fence Tool" & in the same working capacity is the "Bending Tool". The previous tool, the Fence Tool, U.S. Pat. No. 1,531,001, and dated May 29, 1922 hadappearance similarities to the tool of the present invention in that it also included end portions with slots therein for grasping fence wire but, was dissimilar in a few respects. 1) The working portions of the present invention are specificallylocated at one end of the tool & the working part of the Fence Tool is on both ends. 2) The dimensions of the present invention includes: an intermediate bent radius section which is designed for the correct function of the device. The Fence Tool isused for the connection with the proper installation of fencing or fence wires on posts, therefore it is not used in the same working capacity as the Brick Mason Wire Bend.The Bending Tool, U.S. Pat. No. 1,736,585, and dated Jul. 31, 1928 have the purpose of carrying out clip bending operations. Even though this is a tool used in construction it is not specifically designed to carry out the functions of bendingtire wire, truss wire, ladder wire, z-tie wire, & rectangular wire.BACKGROUND OF INVENTIONObjects and AdvantagesAccordingly, besides the objects and advantages of the wire bender described in the above patent, several objects and advantages of the present invention are: a) different gauges on the jaws in order to use on different brick mason wires; b) thedevice is a hand tool which will be more durable than the stamp (heated) device because of the durability of the en

Patents-433 — Fri, 24 Sep 2010 16:43:13 GMT

shared by: Patents-433 on: Friday, September 24, 2010

The present invention relates generally to a cable tie installation tool, and more specifically, to such a tool having an ergonomic trigger mechanism.As is well known to those skilled in the art, cable ties (or straps) are used to bundle or secure a group of articles such as electrical wires or cables. Cable ties of conventional construction include a cable tie head and an elongate tailextending therefrom. The tail is wrapped around a bundle of articles and thereafter inserted through a passage in the head. The head of the cable tie typically supports a locking element which extends into the head passage allowing the tail to beinserted through the passage but preventing retraction of the tail through the passage in the head. Two longitudinally separated portions of the tail are thereby secured to the head to define a loop for holding together the group of articles.In practice, the installer manually places the tie about the articles to be bundled, inserts the tail through the head passage and then manually tightens the tie about the bundle. At this point, a cable tie installation tool is used to tensionthe cable tie. One type of such a cable tie installation tool includes a housing which is generally pistol-shaped where the housing has a barrel into which the tail may be inserted for application of the tension. The housing has a grip which dependsfrom the barrel. The tool includes a trigger mechanism having a trigger member located under the barrel and in front of the grip. The trigger member is elongate and in generally depending relation relative to the barrel such that, when the heel of thehand of a user is placed against the grip such that the fingers of the user's hand extend forwardly, the fingers may encircle the forward surface of the trigger member. Forcibly drawing the fingers toward the heel of the hand, i.e., squeezing thetrigger member and grip, causes the trigger member to be displaced toward the grip. The trigger mechanism extends into the

The subject-matter of the invention is a device for aligning springs during transport of the springs from a spring winding machine to a spring interior assembly automatic machine.BACKGROUND OF THE INVENTIONWith the known automatic manufacture of spring interior mattresses, springs manufactured on a spring winding machine are taken off by a transport star with several arms, if desired knotted at the ends and additionally subjected to a heattreatment. At the ends of the arms there are arranged gripper hands which remove the springs from the spring winding machine and hold these rigidly during transport. The springs are transferred from the transport star to a transport belt pair and areintroduced by this transport belt pair into a spring interior assembly automatic machine. In the spring interior assembly automatic machine the springs are finally connected to one another with spiral wires to be joined together into a spring interiorof a predeterminable size. The springs manufactured on the spring winding machine, without additional measures adjusting the springs, reach the transport belt and thus the spring interior assembly automatic machine aligned more or less equally, i.e. theends of the wires in the region of the end rings lie in each case more or less at the same location. Furthermore, this means that, for example, the last springs of a row are aligned outwardly and thus penetrate through the mattress material. In orderto prevent this, usually the last spring is rotated by 180 about its own axis so that the free ends or the two knots of the ends or knots of the last springs are aligned towards the second to last spring. It is, however, often desirable to arrange thesprings in pairs with the knots or spring wire ends lying opposite one another. There are already known various devices for this purpose, i.e. the alternate alignment of the knots. From DE-A1 19542847 with a spring led from the rotary star from aspring winding device, it is known within the t

Magazine Strip For Ratchets And Tool For Handling The Same - Patent 7082968

Patents-433 — Fri, 24 Sep 2010 09:08:34 GMT

shared by: Patents-433 on: Friday, September 24, 2010

For the mechanical binding of articles, in particular cable harnesses, by means of tie loops, the ends of which are held by tie ratchets, the tie ratchets are fed to the binding tool in the form of a magazine strip in which the tie ratchets areconnected to one another by flexible webs which in each case are cut in the tool before use. If the webs are severed only by one cut, projecting stubs remain behind. It is certainly also known to avoid these stubs by the webs being removed essentiallycompletely by two cuts executed at their ends. However, this results in scrap, which in many applications (for example in aircraft or satellite construction) must not be left in-situ in an uncontrolled manner and is therefore undesirable. The inventiontherefore assumes that a stub piece remains on the ratchet when the web is severed. This stub piece may be sharp-edged and may lead to a risk of injury, in particular if the separating cut is not executed in the center (EP-B-297 337, FIG. 3) or if it isarranged on a laterally projecting flange (U.S. Pat. No. 4,610,067, FIG. 1). But even when the web is cut symmetrically and projects directly from those walls of the ratchets which are parallel to one another, it is relatively long in relation to thedimensions of the ratchet (U.S. Pat. No. 4,680,834, FIGS. 6 to 8).SUMMARY OF THE INVENTIONAn object of the invention is therefore to reduce the problem of the risk of injury on account of the web stub projecting from tie ratchets. The solution according to the invention consists in the provision of a magazine strip of tie ratchetswhich are provided for holding the ends of ties and binding elongated articles such as cable harnesses and are connected to one another by webs. These webs have a length of not more than 1 mm and/or one eighth of the ratchet dimension in the directionof the magazine strip. By the correlation between the known feature that the width of the web is not greater than half the width of the ratchet and the no

shared by: Patents-433 on: Thursday, September 23, 2010

1. Field of the InventionThe present invention relates to lead forming of a semiconductor device.2. Description of Prior ArtA semiconductor device has leads extending through two sides of a resin package. In a fabrication process of semiconductor device, the leads are formed after the semiconductor device is covered with a resin. For example, when gull-wing typeleads are formed in a prior art process, a semiconductor device, after being covered with a resin, is put between top and bottom dies for preliminary bending, so that lead parts extending from the two sides of the semiconductor device are bent in apress. Next, the semiconductor device is put between top and bottom dies, so that distal portions of the lead parts are bent in the reverse direction in a press. Then, the semiconductor device having the gull-wing leads is put between top and bottomdies for adjustment, to produce a final form.In the above-mentioned lead forming, when the type of semiconductor device is changed or even if the type is not changed, but the shape of the leads is changed, all of the three die assemblies have to be replaced. That is, the dies are neededfor each lead shape of semiconductor device. Therefore, much capital investment, labor and time are needed.In the above-mentioned lead forming, exclusive die assemblies each consisting of top and bottom dies are necessary according to a size of a work to be formed. Therefore, it is proposed to use a general die. For example, in the die disclosed inJapanese Utility Model laid open Publication 60-99033/1985 for bending a work such as a wire or a plate with press work, the position of a top die in a die assembly can be changed vertically. Furthermore, one of die assemblies provided at right and leftsides can be moved horizontally with a screw. It is to be noted that lead forming of a semiconductor device is not described. Further, in an apparatus for bending disclosed in Japanese Patent laid open Publication 6-47445/1994, a die co

BACKGROUNDVoice cables and data cables typically extend from an entrance facility, equipment room or telecommunication closet which interfaces with outside telephone and data connections, from which the voice wires or cables and data wires or cables exitfor distribution throughout the building serviced by the equipment room or telecommunications closet. Large numbers of wires or cables extend from a typical connecting equipment rack or back board and pass through some part of the telecommunicationscloset or other locations to a point where the individual cables are distributed to their terminating locations. When large numbers of wires or cables from one or more patch panels or termination blocks pass through the telecommunications closet, theappearance can be very messy. To improve the appearance of the telecommunications closet or any area where large numbers of wires or cables pass, many cable installers simply wrap the cables and squeeze them together into a tight bundle (or bundles),tying them with hook-and-loop straps or wire ties at a number of spaced intervals along the length of the bundle between entry of the wires or cables into the telecommunications closet and the patch panel or termination block into which the terminatinginstallation is made. Such bundled cable runs typically vary in length from three feet to over 40 feet.

Patents-433 — Thu, 23 Sep 2010 11:30:43 GMT

shared by: Patents-433 on: Thursday, September 23, 2010

The present invention relates to a tool head for use with an automatic cable tie installation system and, more particularly, to an automatic tie tool head including an anti-jam tensioning gear mechanism providing improved performance andreliability.As is well known to those skilled in the art, cable ties are used to bundle or secure a group of articles such as electrical wires or cables. Cable ties of conventional construction include a cable tie head and an elongate tail extendingtherefrom. The tail is wrapped around a bundle of articles and thereafter inserted through a passage in the head. The head of the cable tie typically supports a locking element which extends into the head passage and engages the body of the tail tosecure the tail to the head.Although cable ties are often installed manually, it is desirable in certain applications to utilize an automatic cable tie installation system wherein cable ties are dispensed from a remote dispenser, and thereafter delivered to a tool head forapplication about a bundle of wires positioned within the jaws of the tool head. Automatic cable ties installation systems are well-known in the art, and are disclosed for example in U.S. Pat. Nos. 6,279,620, 4,790,225, 4,498,506 and 3,946,769. Itwill be appreciated that the disclosed tool heads include a plurality of subassemblies each having multiple moving parts, the subassemblies cooperating together to deliver, tension and cut the cable tie. To be commercially practical, the tool head mustbe capable of repeatedly applying a cable tie about the bundle of articles inserted within the jaw assembly without jamming. The tool head must also be able to complete a cycle (wherein one cable tie is wrapped, tensioned and cut) within a sufficientlyshort interval of time.Those skilled in the art will appreciate that prior art tool heads can experience internal jams with respect to the tensioning/strap ejection portion of the tool head. More particularly, the tail of the insta

The present invention relates to a device for bending an extremity of a torsional spring. More particularly, the present invention relates to a device for bending an extremity of a torsional spring so that said bent extremity of the spring maybe used with a plug, such as the ones used for operatively connecting torsional springs to overhead shafts of counterbalancing mechanisms of garage doors and the like.BACKGROUND OF THE INVENTIONIt is known in the art that large, vertical, cable-operated doors, such as commercial and residential sectional garage doors, usually require counterbalancing mechanisms to counterbalance the weight of the door in order to decrease the forcerequired to open the door and also facilitate its closing from a raised to a lowered position. Large sectional garage doors used in commercial and residential applications may be manually or power operated. In either case, but particularly for manuallyoperated doors, counterbalancing mechanisms have been used for many years to counterbalance the weight of the door and control its opening and closing movements so that one person can easily control the operation of the door. Counterbalancing mechanismsare also advantageous for power operated overhead doors since they reduce the power requirements needed for the motor and they lower the structural strength required for the door opening and closing mechanism. In other words, lighter weight, lower cost,door controlling mechanisms may be used if a counterbalancing mechanism is connected to the door to assist it in its opening and closing movements. Furthermore, the provision of a counterbalancing mechanism minimizes the chance of a rapid anduncontrolled closing of the door in the event of a failure of the door opening and closing mechanism, which can result in serious injury or damage.It is also known in the art that a widely used type of counterbalancing mechanism generally comprises a pair of spaced apart cable drums connected to flexible cables, ea

This invention relates to fastening. In particular, it isdirected to a fastening clip and an apparatus for use with that clip, the clip being used to fasten together crossing elongate members and has a specific, but not limiting, use to secure the lattice type structure of reinforcing rods of the type used inthe construction of steel rod reinforced concrete slabs.Concrete slabs as used in the foundation for a building or as a suspended ceiling or floor incorporate an open lattice or grid of steel rods for strength. To prevent these rods from sagging under the weight of the wet concrete until it has set,the rods are tied together. It is usual to secure each rod to each other rod that crosses it along its length. The usual securing method is, at each such intersection, to wrap a short length of wire around both rods and then tightly twist the ends tosecure the rods in place. These wire tying operations are usually undertaken manually using some form of gripping device to twist the wire.Even in relatively small constructions, the time taken to fabricate the reinforced steel lattice is significant adding noticeably to the overall cost of the building construction. Further disadvantages include (1) operator fatigue due to thelarge number of ties to be performed, thus effectively reducing the rate of tying and actually adding to the time and therefore cost of completing the construction; (2) muscular and related problems for the operator as the operator must bend over and/orsquat in order to effect the tie; (3) tying is not uniform being dependent upon the efficiency of the operator, thus potentially leading to the aforementioned sagging of the rods before the concrete sets. Also, after the tie is made, the excess wirelength is cut resulting in small lengths of wire which tend to settle to the base of the wet concrete slab. When this slab is a suspended floor, these wire remnants are visible on an exposed surface where they oxidise leading to unsightly rust stains

Cutting Device For A Metal Band Bundling Apparatus - Patent 7063110

Patents-433 — Tue, 21 Sep 2010 20:57:08 GMT

shared by: Patents-433 on: Tuesday, September 21, 2010

1. Field of the InventionThis invention relates to a metal band bundling apparatus, particularly to one having a cutting device to cut quickly a metal band by pressing with the thumb of a hand only, provided with a simple structure.2. Description of the Prior ArtA conventional metal band bundling apparatus is used for bundling a metal band on an object, with the metal band passing through a guiding device, and then pressing it with a actuating plate to pinch it between the actuating plate and theapparatus body. Then the metal band is pulled tightly to bundle the object.However, the metal band is usually left with a certain length after it is bundled tightly, so that left length has to be cut off directly with another tool, or to be twisted off by clamping with the apparatus. And another tool is necessarybeside the conventional metal band bundling apparatus, as it has no cutting device. Moreover, if the metal band is twisted off, its cut edge may be rugged, or the metal band may be broken if worse.SUMMARY OF THE INVENTIONThis invention has been devised to offer a cutting device for a metal band bundling apparatus, which has a rotatable rod-shaped knife with a blade fitted in a hole of a band guider fixed on an upper end of a first handle of a metal band bundlingapparatus, and a press rod connected in a right angle with a rear end of the knife. The press rod has a bent portion of a preset length to pass over a first and a second handle of the apparatus to reach near a grip of the second handle, and a pressportion continuing rearward to the bent portion is to be pressed by the thumb of a hand of a user for cutting a metal band after bundling around an object. When the press portion of the press rod is pressed by the user, the knife is rotated for acertain angle to cut off the metal band, with pressing action of the thumb of one hand only, with the other four fingers still holding the grips of the two handles, very easy and convenient to operate.
