ABSTRACT:
A transfer finger for feeding small workpieces is pivotally mounted at the forward end of a rod which is adapted to be advanced and retracted by a reciprocating pneumatic actuator. During the initial portions of the advance and retract strokes of the actuator, one or more radially contractible collects frictionally grip the rod and prevent the rod from advancing and retracting the finger until such time as the actuator has pivoted the finger between active and inactive positions.
