Abstract
An actuator assembly comprising at least one prime mover, a shaft having a first end and a second end, the shaft being operatively connected to the prime mover for reciprocal movement, a frame, the shaft being reciprocably movable in the frame, and linkage attached to the frame and operatively connected to the shaft, the linkage being movable between a first position and a second position in response to reciprocal movement of the shaft and a selectively engageable stroke-limiting assembly operatively connected to the shaft for controlling movement of the shaft, either by preventing any movement of the shaft or limiting its stroke a predetermined amount.
