ABSTRACT:
An actuator assembly having a clutch mechanism with an input disc and an output disc. Mechanisms are provided for rotating the input disc and preventing rotation of the output disc with the input disc when the assembly is in a rest condition, and for effecting a rotation transmitting connection between the input disc and the output disc when the assembly is in an actuated condition. A mechanism is also provided for automatically returning the assembly from the actuated condition to the rest condition: (1) if the first input disc is rotated within a given time delay, upon the rotation; or (2) if the first disc is not rotated within the given time delay, upon the expiration of the time delay. Thus, the second output disc can be rotated only once within the time delay, and the second disc is not rotatable at all if the first disc is not rotated within the time delay.
