ABSTRACT:
An escapement having a pair of retractable stops spaced apart lengthwise of a downwardly inclined track along which workpieces are conveyed. The upstream stop is supported for pivotal movement lengthwise of the track so that its leading end is adapted to engage in the cleavage space between a pair of abutting workpieces when the stop is extended regardless of whether the cleavage space is located in exactly the same position for each pair of successive workpieces.
