This is the generic class for:
1. METAL* CASTING - Process and/or apparatusfor shaping of fluid metallic material.
2. MOLD MAKING - Process and/or apparatus, per se, forshaping of fluent material to produce a forming surface to carryout in METAL* CASTING, supra.
3. PATTERN MAKING - Process and/or apparatus for shapinga fluent material to produce a form or pattern to be used in MOLDMAKING, supra.
4. PRODUCT TREATING - Process and/or apparatus fortreating, mixing, or mechanically working the metallic materialwhile molding or while the metallic material is in a mold, i.e.,while carrying out an operation of METAL* CASTING, supra.
5. OTHER - Process and/or apparatus not elsewhere providedfor to perfect or effect METAL*CASTING or MOLD MAKING,supra.
*Throughout this class, the term "metal" isto include pure metal, metal alloys and inter-metallic compounds.
AMPLIFIED STATEMENT OF CLASS SUBJECT MATTER.
This class in general provides for the foundry operations includingfrom those of making the molds and patterns to those of castinga final metal product. These operations, particularly that of castingthe metal, do not have to be limited to a foundry operation in thelocational sense; but may be performed in any physical location, e.g.,cast-welding rail ends in the field.
The metal casting of this class involves the shaping of a freeflowing liquid metal and as such is distinguished from other formsof metal deformation such as metal bending, forging, billet extrustion,etc., where the metal is never free flowing. Also a shaping surfaceis required for placement in the class. For example, forming metal bya shot tower will be found elsewhere. The shaping surface, though,may remain as part of the final product. (See References to OtherClasses, below).
The mold making procedures provided for in this class aregenerally of the sand shaping type although any fluent materialis included such as metal, plaster of paris, ceramic materials andsynthetic plastics. There molds so formed are limited to use inmetal casting operations and are not of general utility. Makingmolds by shaping of solid materials are found in the particularshaping classes except where the operation is combined with a subsequentmetal casting step; in such a case, the operation is provided forin this class.
The pattern making procedures provided for in this class arethose of shaping a fluent material such as wax and other plasticmaterials. Shaping a pattern from solid material such as by cuttingfrom wood are provided for in this class only when followed by afurther foundry operation such as forming a sand mold by using thepattern.
The metal product treating operations provided for in thisclass are those that are performed in conjunction with a metal castingoperation. Alloying of metals while pouring the metal into a moldor while the metal is in a mold is provided for in this class.Any reshaping of the metal while in the mold such as cutting, orsolid deforming are provided for in this class. Also, particularlyin the case of a continuously casting operation, the rolling orbending of the continuously cast product (where the casting is alsoclaimed) is provided for herein if some of the contiguous productis still in the mold.
Other miscellaneous adjuncts which are used to perfect a foundryoperation are provided for in this class if there is not a specificclass which provides for the subject matter. The main items ofthis type are flasks, mold jackets, strippers, and core supportingdevices, e.g., chaplets. See Subclass References to the CurrentClass, below.
