ABSTRACT:
The rotary control timer for an automatic appliance, e.g., a washing machine, is driven by connecting a saddle pawl through a cable or equivalent connector to an element in the appliance that continually oscillates or makes other repeated cycles of movement of substantially constant time duration during operation of the appliance. Prongs on the pawl engage a plurality of peripherally toothed wheels, one of which is connected to the timer cam drum and another of which is free to rotate relative to the cam drum in such manner that a pawl prong continually engages the free rotation wheel while a second pawl prong engages the drum connected wheel only intermittently.
