This is the residual class for a static implement, rather thana machine, having:
A. Structure intended for shaping fluent material only whereinthe structure is so arranged as to define a space or cavity forretaining the fluent material and wherein the fluent material initiallyhaving no definite form conforms to the shape of the space or cavitysolely by gravitational force on the fluent material and changesto a self-sustaining shape which shape is retained even after removalfrom the structure.
(1)Note. The space or cavity may be formed by a mold part cooperatingwith existing structure, e.g., building structure or earth.
B. Implements of the type set forth in subparagraph A abovedisclosed for use with, but not so claimed, means for applying anexternal force to fluent material only for imparting a shape thereto;i.e., a female portion of a male-female couple.
C. Implements disclosed for use with the structures set forthin subparagraphs A and B above for shaping the interior of a hollowcasting, or which make a hole in or through a casting upon separationtherefrom.
D. Implements of the type set forth in subparagraphs A andB above combined with that of the type set forth in subparagraphC above.
E. Structure including molding surfaces intended for shapingand bonding a fluent material with a preform to form a compositeproduct that is separable from at least one molding surface.
F. Essential subcombinations of the structures set forth insubparagraphs A-D above which are separable from the product.
G. Adjuncts, per se, disclosed for use with the structure ofsubparagraphs A-F above which perform some function other than shapingand are not classifiable elsewhere.
