Abstract
Indexing apparatus is disclosed whereby a constantly rotating drive shaft can intermittently drive apparatus driven thereby. An arm carried by the drive shaft pivotally carries a second arm which has means for engaging a cammed surface whereby the pivoted arm is moved radially toward and away from the drive shaft. The rotated output member is mounted for rotation about the longitudinal axis of the drive shaft and includes a projection adapted to be engaged selectively by an engaging member on the pivoted arm as the pivoted arm is rotated in response to the positioning of the camming surface. In the preferred embodiment, the projection is an extended member and the engaging member is initially brought into contact close adjacent the drive shaft and moved radially outward in a decreasing amount whereby the rotated member is smoothly accelerated. Correspondingly, upon disengagement, the engaging member is moved radially outward in an increasing amount to smoothly decelerate the rotated member.
