ABSTRACT:
A backdrive overload clutch mechanism which includes a rotatable drive member and a rotatable driven member mounted concentric with respect to the drive member. A pair of cooperating clutch jaws, including chamfered teeth, are provided with one jaw on each of the drive and driven members for rotation therewith and separable by relative movement between the members longitudinally of their axis of rotation. A first spring normally urges the clutch jaws into driving engagement. A tongue-and-groove disengaging device disengages the clutch jaws automatically in response to relative rotation between the clutch jaws. A second spring maintains the clutch jaws out of driving engagement when the clutch jaws are automatically disengaged.
