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.

Certain specific subclasses in Class 249 do provide for a static mold combined with a perfecting device where the device is also static and integral with the mold or is essential thereto. The following list exemplifies types of subject matter provided for in Class 425 and elsewhere:

a. A mold combined with means for pressing molding material within the mold.

b. A mold combined with a cover having projections penetrating into the fluent hardenable material upon movement of the cover to its operative position.

g. A mold or core combined with means for creating differential pressure within the mold or core for dynamically shaping a molding material.

h. A mold combined with means for feeding material thereto, except that a mold with an integral funnel element or a mold so modified to provide structure especially designed for supporting a feeding means, is classified in this class (249, subclasses 105+).
