ABSTRACT:
An indexing device has a toothed gear actuated by a reciprocating yoke impinging on a tooth to turn the gear and to hold the gear in a fixed position upon further movement of the yoke in the same direction. The yoke is reciprocated through a cam connection with a pivoted lever which in turn is acted upon alternately by two electromagnets. Each stroke of the yoke rotates the indexing gear one tooth.
