ABSTRACT:
An indexing drive has an actuator which reciprocates a ratchet arm along an arcuate path to cause an indexed rotation of rollers during one direction of movement of the ratchet arm which bear on a follower to produce an associated indexed rotation of the follower which may be communicated with a drive mechanism of apparatus to provide an indexed movement of the apparatus. Desirably, when the follower is not being rotated by the rollers, it is restrained from rotation in either direction to prevent movement of the drive mechanism to which it is connected and hence, to prevent movement of the apparatus associated with the drive mechanism.
