Abstract
The knob spindle of a self contained electrically controlled door lock is locked and unlocked by a unidirectional miniature electric motor. The motor drives a lock pawl to and from locking position through cyclically operable mechanism including an energy storing spring. The mechanism invariably operates through a cycle and, if the pawl is prevented from moving, energy will be stored in the spring to subsequently move the pawl, thereby preventing stalling of the motor and undue drain on the batteries.
