CLASS 249,	STATIC MOLDS
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This is the residual class for a static implement, rather than a machine, having:

A. Structure intended for shaping fluent material only wherein the structure is so arranged as to define a space or cavity for retaining the fluent material and wherein the fluent material initially having no definite form conforms to the shape of the space or cavity solely by gravitational force on the fluent material and changes to a self-sustaining shape which shape is retained even after removal from the structure.

(1) Note. The space or cavity may be formed by a mold part cooperating with existing structure, e.g., building structure or earth.

B. Implements of the type set forth in subparagraph A above disclosed for use with, but not so claimed, means for applying an external 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 forth in subparagraphs A and B above for shaping the interior of a hollow casting, or which make a hole in or through a casting upon separation therefrom.

D. Implements of the type set forth in subparagraphs A and B above combined with that of the type set forth in subparagraph C above.

E. Structure including molding surfaces intended for shaping and bonding a fluent material with a preform to form a composite product that is separable from at least one molding surface.

F. Essential subcombinations of the structures set forth in subparagraphs A-D above which are separable from the product.

G. Adjuncts, per se, disclosed for use with the structure of subparagraphs A-F above which perform some function other than shaping and are not classifiable elsewhere.
