DEFINITION

Classification: 269/229

(under subclass 216) Device wherein the actuating means includes (A) cam* means or (B) a tampered or sloped block (acting as an inclined plane) for effecting relative jaw movement.

(1) Note. The wedge means must include mechanism to seat or shift said means, to be considered as an actuating means.

(2) Note. See subclass 165, (3) Note for line with respect to insert block adjustment.

(3) Note. A helical element coacting with a mating threaded element or threaded segment, so that the only relative movement between said elements is about and/or along a common axis, is considered to be a screw-nut type of mechanism rather than a cam or gear means. In the case of a threaded segment the relative axial movement of the segment with respect to the helical element is along a line parallel to the helical axis. The provision of means for relative radial movement between the elements is considered to characterize the mechanism as a cam type means.
