Abstract
The actuator assembly is a unitary structure comprising a self-braking rotary power unit and a spring clutch mounted on a frame and interconnected so that the spring clutch transmits the rotary driving force of the power unit to a load to thereby effect its movement in one direction, the power unit and spring clutch co-acting when the power unit is inoperative to hold the load in a selected position. An electro-magnetic device coacts with the spring clutch to cause the spring to disengage and allow the load to move in a direction opposite of the one direction.
