Abstract
A motorized lock actuator is provided for moving a locking bar in a mortise lock. The lock actuator includes a pivot hub having a pivot axis and a shaft-receiving aperture, a spring mounted on the pivot hub, a motor, and a rotatable drive shaft inserted into the shaft-receiving aperture formed in the pivot hub. The motor rotates the drive shaft and thus the pivot hub to urge the spring into engagement with the locking bar so that the locking bar is moved either to its locked or unlocked position. A slip-clutch mechanism is provided in the pivot hub to establish a driving connection between the drive shaft and the pivot hub.
