Abstract
Abstract An electrically controlled manual operating unit for a door lock, adapted to be assembled in place of conventional manually operated means on the lock. The housing of the unit is shaped like a usual type of key controlled tumbler cylinder, and mounts a knob in freely rotatable relation to a lock actuating cam. The cylinder contains a solenoid that must be energized to engage a clutch in order to permit rotating movements of the knob to rotate the cam.
