DEFINITION

Classification: 242/482.8

Rotary cam and linearly shifted follower:

(under subclass 482.4) Subject matter in which the second element (follower) moves along a straight line as a result of rotation of the first element (cam).

(1) Note. In this subclass, the take-up or spool may act as the rotary member or cam.

(2) Note. To be a considered a cam and follower for this subclass, (1) the follower must move along the surface of the cam, i.e., the point of contact between the cam and follower must change relative to the cam and (2) the change in position of the follower must be causally related to this change in the position of the point of contact. For example, a pin rotating about an axis transverse to the length of the pin and extending radially of a non-rotating, longitudinally-shiftable threaded shaft and engaging with the thread of the shaft is not a rotary cam and follower arrangement, but a non-rotary cam and rotating follower

classifiable in the parent subclass.
