ABSTRACT:
The drive train of an appliance timer includes a slip clutch formed of a triangular spring meshing with the outer flat surfaces of a hexagonal drive shaft. The slip clutch is incorporated into a drive pinion in the appliance timer drive train. Excessive torque causes the walls of the triangular spring to resiliently bend outward under rotational pressure from the drive shaft, permitting the drive shaft to rotate without rotating the drive pinion. When used in an icemaker, the slip provided by the clutch alleviates the need for an expensive, stallable motor.
