Tool Press Drive - Patent 8146473
CROSS REFERENCE TO RELATED APPLICATION(S) Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not applicable.REFERENCE TO A MICROFICHE APPENDIX Not applicable.TECHNICAL FIELD This invention relates to a pressing mechanism for a workpiece tool particularly usable to work on a metal workpiece, such as a structural angle, for stamping, creating holes, cutting and shearing.BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS POSED BY THE PRIOR ART Structural modifications for specific intended uses during manufacture of the workpieces are commonly required. For example, angle irons or structural angles (i.e., angle irons) often require that multiple holes be provided at various locationsalong the angles. Given the strength of the materials of the angles, significant forces are commonly required to create those holes, and thus significant mechanisms are required to generate those forces. Such forces are similarly required for otheroperations which might be required in which holes completely through the angle may not be required, for example, stamping identifying characters in the surface of the angle. Machines have, of course, been used which can create holes (e.g., by punching or drilling), or stamp identifying information, in such workpieces, usually in a facility where the workpieces are being worked on (e.g., where a long blank is beingpunched to provide whatever holes are required for the intended use of the part pieces, with individual elements being sheared from the blank to form the individual part pieces). Workpieces such as structural angles which are not simply flat and/or are made of strong material can be particularly difficult to work with in creating holes. For example, structural angles may have two longitudinal members or legs connectedat right angles along an edge (often by bending a single flat longitudinal member along a line extending in the longitudinal direction), and typically are made of strong metals such as steel or
Sheet Material Dispenser - Patent 8146471
FIELD The field relates to dispenser apparatus and, more particularly, to sheet material dispensers.BACKGROUND Dispensers for flexible sheet material in the form of a web, such as paper towel, cloth towel, tissue and the like, are well known in the art. Certain types of sheet material dispensers are powered through some or all of a dispense cycle by adrive mechanism including one or more springs. In such dispensers, a dispense cycle is initiated when a user grasps and pulls the sheet material "tail" which is the sheet material end which extends out from the dispenser. Pulling of the tail causesmovement of the sheet material to rotate a drive roller and energizes a spring or springs attached to the drive roller. The spring or springs then power rotation of the drive roller through completion of the dispense cycle. Rotation of the drive rollerpowers operation of a cutting mechanism carried on the drive roller to fully or partially sever the web. A relatively high spring force is required in order to power the drive roller and cutting mechanism to fully or partially sever the sheet materialweb to provide a single sheet for the user. Typically, a pull force of about two pounds or more is required to overcome the force applied to the drive roller by the spring or springs. While these dispenser types are very effective for their intended purpose, there is opportunity for improvement. For example, the relatively high pull force required to rotate the drive roller to initiate a dispense cycle can cause a problemknown as "tabbing." Tabbing refers to a condition in which a small portion of the sheet material tail tears off in the user's hand. The small portion which is torn off of the tail is referred to as a "tab." The tab includes insufficient material to meetthe user's needs. And, the remaining tail extending from the dispenser may be inadequate for a user to grip to initiate a new dispense cycle, thereby potentially disabling the dispenser. Tabbing can be a par
Paper Cutting Device Having Receiving Part - Patent 8146472
TECHNICALFIELD The present invention relates to a cutting device for cutting multiple sheets of paper or the like stacked in layers, and more particularly, to a cutting device for cutting paper or the like provided with a blade receiving part on a paperretaining frame.BACKGROUND ART In cutting devices for cutting paper or the like, there is "push cutting", in which a cutter is pushed in a direction perpendicular to the edge of the blade when cutting, and "pull cutting", in which the cutter is pushed while moving parallel tothe edge of the blade when cutting. For example, in JP-A-2001-88084 and the like, a method is employed that emphasizes the latter "pull cutting", in which the edge of the cutter blade bites slightly into a blade receiving surface of a receiving part,and at the same time, in order to improve sharpness, the paper is cut while moving parallel to the blade receiving surface. When cutting paper using the "pull cutting" described above, material is used for a blade receiving surface 41 such that an edge 44 of a cutter 43 bites into the blade receiving surface 41 of a receiving part 40 as shown in FIG. 5. This isbecause if a hard blade receiving surface 41 into which the blade edge 44 could not bite were used, the blade edge 44 of the cutter 43 would very quickly become unable to cut. Therefore, a slight groove 42 is formed in the blade receiving surface 41 bythe blade edge 44 of the cutter 43. Typically, taking into consideration "undulation" of the blade edge 44, unevenness of the blade receiving surface 41 and so forth, the bite is set to a depth of approximately 0.3 mm to 0.7 mm. Moreover, in order to allow the blade edge to bite,metal or the like having a large elastic modulus cannot be used for the material used for the blade receiving surface of the receiving part, and typically a resin such as polypropylene (PP) is used. However, when the cutter is moved parallel to the blade receiving surface with the blade edge biting in, the blade receivin
System And Method For Forming Shaped Grooves In An Airport Runway - Patent 8146475
1. Field of the Invention In general, the present invention relates to the structure of airport runways. More particularly, the present invention relates to the methods used to create grooving patterns in airport runways. 2. Prior Art Description Most all paved surfaces are impervious to water. Consequently, any low-point or depression in a paved surface has the potential to cause puddling during a rain storm. Furthermore, if the rate of precipitation excesses the rate at which watercan flow off the payment, puddling will inevitably occur. If the paved surface is an airport runway, such puddling can be extremely dangerous. If the wheels of an airplane roll through a puddle during takeoff or landing, the wheels of the airplane canhydroplane. This can cause the airplane to turn on the runway and/or prevent an airplane from stopping or reaching takeoff speeds prior to the end of a runway. It is for these reasons that many airports cut grooves into the surfaces of the paved runways. According to the U.S. Federal Aviation Administration (FAA), runway grooves should be 1/4 inch wide, 1/4 inch deep and should be spaced one and ahalf inches apart. In theory, the grooves provide flow channels for water. Any water on the runway should flow into the grooves and should then flow to the sides of the runway. Furthermore, even if some puddling does occur, the grooves provide roomfor the water to flow as the wheels of the airplane pass. Consequently, hydroplaning can be avoided. Traditionally, grooves are cut into the pavement of a runway using a standard diamond embossed cutting blade. The cutting teeth on the blade have a uniform thickness. Consequently, when the blade cuts into the pavement, it produces a groovethat has a square or rectangular cross-sectional profile. Grooves with rectangular cross-sectional profiles are not without disadvantages. Grooves of such a configuration have right-angle top edges where the pavement encounters the cut groove. These sha
Wood Cutting Saw Chain And Replaceable Cutting Members - Patent 8146474
The present invention is directed to a chain for cutting wood such as chain saws andtimber harvesters.BACKGROUND OF THE INVENTION There are a variety of cutting devices in numerous applications including masonry, machining, metal cutting, glass cutting, wood cuffing and stone cutting, which can employ a chain, rotary blade or other cutting element. Saw chains employ achain design and material components unique to the particular application. In many cases the chain and teeth of one saw have a design that cannot be used in a saw for a different application. Also, chain tooth materials necessary for one applicationsuch as masonry, are not well suited to other applications such as wood cutting. In the timber industry, saw chains of chain saws and timber harvesters are designed to cut the wood of trees. The conditions of wood to be cut influence the choice of material that is used for the cutting teeth of the saw chain. For example,under normal wood cutting conditions, saw chains having steel teeth are used. However, when cutting trees in an area where there are nails, staples or other metal articles that may have been inserted into the trees such as in areas near old farmland,saw chains employ more costly carbide-brazed steel cutting teeth because they can cut through metal articles in the tree and through the wood without becoming excessively dull. The teeth of all saw chains undergo expected wear. This is typically addressed by the time-consuming process of sharpening the teeth or changing-out the dull chain with a sharpened chain. This delay in cutting causes a costly decrease inproductivity of the cutting operation. Attempts have been made to employ removable inserts usually made of steel. These inserts have taken on various designs but, in general, have been unsuccessful and are not used widely if at all. U.S. Pat. No. 2,583,243 discloses a chain sawwhich employs removable teeth which are wedged into the slot of a head of a saw chain link. U.S. Pat.
Device And Method For Compressing And Cutting Soft Food - Patent 8146468
1. Field of the Invention In general, the present invention relates to food presses and cutting presses that are used to compress and cut food, respectively. More particularly, the present invention relates to manually operated devices that are used to squeeze and cutsoft food, such as tofu. 2. Prior Art Description Tofu is made from lightly compressed and aged soy bean curd. As such, tofu has a gelatinous consistency with a high moisture content. In order to keep tofu from drying out, it is often packaged in a liquid, such as water or soy whey. The problem associated with liquid packaged tofu is that the tofu is saturated with the surrounding liquid. The tofu, therefore, has very little capacity to absorb other liquids and other flavors when it is used in cooking. To remedy this problem, tofu is typically conditioned prior to use. Some of the liquid saturating the tofu is removed so that the tofu has the ability to absorb flavors during cooking. Often the tofu is wrapped in a towel that absorbs some ofthe liquids within the tofu. Sometimes, tofu is placed in a press so that some of the liquid in the tofu can be squeezed out of the tofu. Prior art presses are exemplified by U.S. Design Pat. No. D540,628 to Meyers, entitled Tofu Press. Due to the gelatinous nature of tofu, it can be only lightly compressed before it deforms out of shape. It is for this reason that tofu presses are commonly made with rectangular compression chambers. This enables a piece of tofu to be cut tosize and precisely placed in the press. Since the press and the tofu are both equal in size, the tofu cannot laterally deform when compressed. Presses compress the tofu to remove excess liquids. As a block of tofu is compressed, the block of tofu becomes slightly thinner as liquid is freed from the tofu. The compression of the tofu better bonds the molecules of the tofu byeliminating some of the water molecules that are in the tofu. This makes the tofu more durable and easier to
Container For Producing Predetermined Food Portions - Patent 8146469
The invention relates to containers, and more specifically to a container for receiving ingredients to be cut into predetermined portions.BACKGROUND OF THE INVENTION Many types of foods are prepared and placed into a pan or container and then cut into predetermined portions. A chef or baker typically employs a pan to cook or provide a desired shape to the food being prepared. The completed food iscontained within the pan and typically cut into portions prior to serving or storing. Usually, the food contained within the pan is divided into a number of equally sized portions. Equal sized portions facilitate the aesthetic presentation of the food. Additionally, in commercial baking or restaurant operations, consistency in portion size is an essential aspect of meeting customer expectations, controlling the cost of the food sold, and determining the quantity of food that must be prepared. One method of dividing the food in consistently sized portions is by using a ruler and a knife. The ruler is used to measure the desired portion sizes and mark the upper surface of the food. The ruler is then aligned with the marks andemployed as a straight edge to guide the knife as the food is cut. Although this method can be effective, it is a time consuming multi-step process subject to measurement errors and requires a steady hand to evenly cut along the straight edge of theruler. Prior art devices such as those illustrated in U.S. Pat. No. 892,552 to Rexer, U.S. Pat. No. 6,009,786 to Hjelden, and U.S. Pat. No. 6,745,660 to Caputo include a guide for a knife or a plurality of cutting blades to facilitate cuttingfood in equal sized portions. However, these devices typically require a skilled steady hand to cut the equally sized portions; or are a multi-piece device that must be assembled and attached to an associated baking pan. It would be desirable to have a container and an associated cutting blade for efficiently cutting food within the container into predetermin
Die Stamping System - Patent 8146470
BACKGROUND 1. Technical Field The present invention relates to a die stamping system and, particularly, to a die stamping system having a sliding block with a punch. 2. Description of Related Art The objective of a typical fine die stamping apparatus is accurate cutting and punching of a workpiece. Such apparatus usually includes an upper die and a lower die, with one or more punches associated with the upper die and a punch baseassociated with the lower die, movable with respect to the lower die. To ensure necessary precision during formation of parts, it is common to provide a locating configuration in a workpiece. Referring to FIG. 5, a conventional locating configuration 1of a workpiece 2 is shown. The location configuration 1 of the workpiece 2 is formed by means of a conventional half-cut punch method. However, the location configuration 1 may decrease the strength and aesthetic appearance of the workpiece 2. It is desired to provide a die stamping system having a sliding block that can overcome the described limitations.SUMMARY In accordance with the present invention, a die stamping system includes an upper die, a sliding block, a lower stripper, a die holder connected to the lower stripper, and a lower die-set moveably connected to the die holder. The sliding blockincludes a body with a wedge-shaped head facing downwardly, a punch connected to the body, and two arms on opposite sides of the body, respectively. The lower stripper matches the upper die and has an aperture for passage of the punch therethrough. Thedie holder is connected to the lower stripper and includes an opening for passage of the body therethrough, as well as a first notch loosely receiving the two arms. The lower die-set is movably connected to the die holder and includes a wedge-shapedpadding block facing up, supporting the wedge-shaped head of the body. Other novel features and advantages will become more apparent from the following detailed description when taken in conjunc
Wire Bundle Wrap Cutting Tool - Patent 8141465
The disclosure generally relates to a device for electrical servicing, and particularly to an improved cutting device for cutting wire bundle wraps.BACKGROUND In many different applications, electrical wiring may be extensively utilized. For example, in an airplane, wires must run between various parts of the plane to provide power, signaling, and other capabilities. For organization and tidiness,wiring is grouped together in bundles and secured through different means. One of such means is through the use of wire bundle wraps, commonly referred to as "panduit," which may used to retain groups of individual wires into bundles. For maintenanceor other reasons, wire bundles and wire bundle wraps may need to be serviced or reworked, which may require that the wire bundle wraps are cut. Many types of cutting devices may be used to cut wire bundle wraps. However, existing tools make such work difficult, in the sense that wires in the wire bundle may accidentally cut and work in hard-to-reach areas is very difficult toaccomplish. Using existing cutting tools requires extra care and time when reworking a wire bundle, especially in hard-to-reach and poorly lit areas. Thus there is a need for an improved wire bundle wrap cutting tool which allows for safe and easy cutting of wire bundle wraps, convenient access to hard-to-reach areas, and which does not damage wires.SUMMARY In accordance with a preferred embodiment of the present disclosure, a wire bundle wrap cutter is provided comprising a shaft, a cutting end, and a handle end, a cutting head extending in a transverse direction from a top side of the cuttingend, the cutting head comprising a generally U-shaped channel defined by a tongue portion and a blade enclosure for receiving a wire bundle wrap to be cut; a cutting blade having a cutting edge, wherein the cutting blade is disposed in a slot in theblade enclosure, the slot being disposed in a direction perpendicular to the shaft, such that the cutting edge of t
Punch Device For Piercing Hydro-formed Member - Patent 8141466
The present invention relates to a device and method for forming apertures in a hollow member. More specifically, the present invention relates to a device and method for piercing a hydro-formed member to create an aperture therein.BACKGROUND OF THE INVENTION Hydro-forming of steel and other metal hollow members is becoming increasingly common. With hydro-forming the cost of manufacture of hollow members can be reduced, in comparison to conventional stamping, welding and other manufacturingtechniques. Further, the quality (strength, tolerances, etc.) of the finished hydro-formed member can exceed the quality of members formed with conventional techniques. After a member has been hydro-formed, it typically requires a series of additional manufacturing operations and/or forming steps. One common post-forming operation is the need to form one or more apertures in the member and much effort haspreviously been devoted to forming these apertures in the member via piercing when the formed member is still in the hydro-forming die. While piercing is now commonly used to form desired apertures in hydro-formed members, difficulties still exist with piercing technologies. In particular, the size of the cylinders required to perform the pierce can restrict the number ofapertures that can be formed in any region of the member, as insufficient volume may be available to accommodate the cylinders in the region of interest. Further, the quality (shape and/or clean cut of the edges) of the aperture may not be as good asdesired. To address these issues, piercing systems which employ a negative pierce have been proposed. In the proposed negative pierce system, the piercing punch is retracted during a portion of the hydro-forming cycle such that the portion of the formedmember to be pierced is extruded outward from the formed member. The piercing punch is then extended into the extruded portion to pierce the resulting weakened area and form the desired aperture. By first extru
Fruit Slicing System And Method Of Use - Patent 8136433
The present invention relates to a fruit slicing system and method of using same, and more particularly to a fruit slicing machine that slices fruit into a plurality of wedges.BACKGROUND OF THE INVENTION The food service industry has a need for sliced fruit. Often the fruit is sliced by hand. This can be inefficient, inconsistent and the sliced fruit has a short shelf life. Accordingly, a need exists for an automated system for slicing fruitthat overcomes the disadvantages described above.SUMMARY OF THE PREFERRED EMBODIMENTS In accordance with a first aspect of the present invention, there is provided an apparatus for cutting fruit. The apparatus includes a frame, at least first and second cutting stations, at least one receptacle in which the fruit is receivedthat includes a plurality of extensions protruding outwardly from an outer circumference thereof, and a conveyor that conveys the receptacle from the first cutting station to the second cutting station. The frame includes a kicker. In use, the objectis cut along its vertical axis at the first station, the receptacle is then rotated about its vertical axis as a result of one of the extensions contacting the kicker, and the object is cut at the second station. In a preferred embodiment, the at leastone receptacle is mounted on and rotatable with respect to a mounting plate, the extensions define a rotational path, the mounting plate includes a brake mechanism extending upwardly therefrom, and the brake mechanism is in the rotational path of theextensions. In accordance with another aspect of the present invention, there is provided a method of slicing fruit. The method includes the steps of placing the fruit in a receptacle, positioning the receptacle in a first position, conveying thereceptacle along a path on a conveyor to a first cutting station, cutting the fruit in half along its vertical axis at the first cutting station, rotating the receptacle about its vertical axis to a second position, convey
Food Product Slicer Knife And Associated Slicer And Knife Removal Tool - Patent 8136435
This application relates generally to a slicer having a removable slicer knife, and more particularly, to a knife, related knife mount system and knife removal tool.BACKGROUND Commercial food product slicers are widely utilized as rapid and effective means for slicing meat, cheese, vegetables and other food products. The slicers commonly include a rotatable, disc-like blade, and a reciprocating tray that brings thefood product into contact with the rotating blade to cut a slice from the food product. Most slicers also include a movable gauge plate that adjusts the position of the food product relative the blade, which varies the thickness of the slices cut off ofthe food product. The gauge plate typically has a "closed" position, wherein the gauge plate is slightly raised relative the blade such that the food product cannot be cut by the blade. Most existing slicers have the knife mounted permanently by using screws. The knife cannot be removed except by use of a conventional tool to remove the screws. One existing slicer includes a special tool to remove knife. The knife is permanently mounted on the mounting hub by using screws, then a rotatable plate and a fixed plate are mounted on the top of the knife through another set of the screws,then the knife and mounting hub are inserted on the slicer through three spring loaded pins on the knife drive shaft. The rotatable plate has ramp features on it. By rotating the rotatable plate 90 degrees using a tool, the three pins move up, and theknife and mounting hub are held through the rotatable plate by these pins. To remove knife, the tool is inserted into the center hole, aligning three drive pins on the tool with the three notches on the rotatable plate. The rotatable plate is rotatedback 90 degrees to unload from the three spring loaded pins and retreat the knife and mounting hub from pins. This design is expensive and complicated. The knife and the mounting hub are removed together, leaving an opening on
Saw Chain Link With Offset Footprint - Patent 8136436
The present invention relates to the field of saw chains, and in particular to a saw chain having one or more links with foot portion with an offset feature.BACKGROUND Chain saws typically include an endless saw chain disposed to articulate around a saw bar comprising various coupled links including cutter links, drive links, and tie straps. The cutter links and tie straps are typically in sliding engagementon bar rails of the saw bar. The cutter links can be used for cutting wood, concrete, ice and other materials. The cutter links and tie straps which ride on the saw bar rails are generally sized to match the bar rail width/thickness. This allows the bar rail and the respective bottoms of the cutter links and tie straps to wear against each other evenlyand keep one or the other from getting a non-worn area known as a "knife edge". A knife edge is undesirable because it can cause tight joints or burrs or be a source of crack initiation. The kerf of the saw chain is generally the width of the cut that a chain makes as it cuts through material. It is controlled by the distance from the farthest outside offset dimension of the cutting portion of the cutter link on respectiveopposite sides of the chain. Making the kerf of the chain as narrow as possible is desirable to minimize the power necessary for cutting. Prior attempts to narrow the Kerf, however, has generally resulted in 1) knife edging occurring on the bar railsand/or the links by using thinner chain components; 2) an unacceptable decrease of kerf to bar clearance; 3) weakening of and/or limiting the length of the bar by virtue of narrowing the bar in conjunction with narrowing the components and/or to maintaina satisfactory kerf to bar clearance; and 4) reducing the cutter offset, which undesirably reduces the amount of clearance between the kerf wall and the bar, thereby negatively affecting the chip flow up the side of the bar and chain.

Cutting Blade Control System, Particularly For Cutting-off Machines For Cutting Logs Of Web Material - Patent 8136434
BACKGROUND The present invention refers to a cutting blade control system, particularly for cutting-off machines for cutting logs of web material. In the production of rolls of web material, such as paper, tissue paper, non-woven fabric, plastic materials etc., logs or batons are initially produced and must subsequently be cut into rolls of the desired length. For this purpose use is madeof special cutting-off machines, sometimes called log saws, which have one or more cutting discs or rotating band saws that are cyclically lowered onto the logs to be cut. The cutting blade is moved towards the logs to be cut, which are conveyed on aconveyor driven by a chain extending around idler wheels. In disc or band saw cutting-off machines a problem that reduces the production rates, even drastically, is the overheating and the consequent deformation of the cutting blade. Since the cutting blade, to perform the cutting of the log, musthave a high speed of rotation during cutting, high friction is generated between the surface of the blade and that of the log to be cut, which causes an excessive overheating of the blade. Once a threshold temperature has been reached, which variesaccording to the material and to the shape of the cutting disc, a slackening and a thermal dilation of the disc take place, leading to deformation thereof. This deformation is due to the residual tensions induced in the cutting disc during manufactureto cause its surface to take on the desired planarity. Consequently, once a threshold deformation of the blade has been reached, the cutting of the log must be interrupted to allow the cooling thereof, otherwise the excessively hot blade could be further deformed, becoming damaged or even breaking. Machine idle times to allow the blade to cool are calculated, entirely empirically, on the basis of the operator's professional skill. Consequently, to avoid damages to the blade, there is a tendency to stop the machine within wide safety limits, withthe r
Clamping And Cutting Apparatus For Conveyor Belts - Patent 8132489
The invention relates to an apparatus for cutting conveyor belts, and more particularly, an apparatus that clamps across the width of a conveyor belt and cuts the conveyor belt therealong.BACKGROUND OF THE INVENTION For forming a belt splice, typically a conveyor belt is cut across its width at two locations to form squared ends of the belt that are then joined or spliced together with mechanical fasteners. Applicant's assignee herein has a belt cutter(the "840 Series Belt Cutter") that has a long clamp bar with a pair of spring loaded, clamping mechanisms that clamp the conveyor belt between the clamp bar and a long base member. Thereafter, a cutting handle is operated to drive a cutting bladethrough the belt from one side of the belt to the other. In this belt cutter, the clamp bar has an inverted U-shaped configuration with opposite legs of the clamp bar clamping on the conveyor belt on either side of cutting blade. It has been found thatthis clamping arrangement on either side of the cutting blade requires that an operator apply an unduly large amount of torque on the drive handle for driving the cutting blade through the belt. The applicant's assignee's prior belt cutting apparatus had the pair of spring loaded clamping mechanisms associated with the clamp bar at locations approximately midway between the center of the long clamp bar and the adjacent clamp bar end. The positioning of the clamp mechanisms closer to the center of the clamp bar is in an effort to minimize deflection of the clamp bar at the center portion thereof during clamping. These spring loaded clamping mechanisms generate concentrated clampingforces between the clamp bar and base member on the conveyor belt at the locations under the clamping mechanisms. Since the long clamp bar member extends well beyond the clamping mechanisms, these outer portions of the long, clamp member tend to bowupwardly with application of the high clamping forces to the conveyor belt. Further, since these cl
