Abstract

1,103,685. Ratchet gearing. CONTROLS CO. OF AMERICA. 5 Oct., 1966 [24 Oct., 1965], No. 44401/66. Heading F2Q. [Also in Division H1] A ratchet-and-pawl drive for a timer comprises a pawl 34 pivoted on a lever 18 engaging a motor-driven snail cam 20, the pawl 34 acting on the ratchet-wheel 10 which is on a cam-shaft of the timer. A stop pawl 42 is pivoted at 38 and both pawls engage the same tooth of the ratchet-wheel when the pawl 34 has completed a step (Fig. 1). Movement of the lever 18 when released by the cam is limited by a stop 40 which is engaged by the end of pawl 34. In a modification (Figs. 4, 5, not shown), the stop consists of a surface (74) on the stop pawl (70).
