DEFINITION

Classification: 100/260

(under subclass 214) Apparatus having means to move a pressure surface in a material compressing direction, said means including a force transmitting member which, after completion of the compressing stroke, continues to move in the same direction as it did when moving the surface through the compressing stroke, but has means to discontinue the transmission of moving force to free the surface to return under the influence of the compressed material or of the continuing pull of a biasing spring or weight.

SEE OR SEARCH THIS CLASS, SUBCLASS:
