Abstract
A safe door lock with a servo motor operated cam is described. A retracting lever is pivotally secured to the locking bolt and is displaced on a pivot connection with the bolt by the cam. The position of the cam and the bolt are detected by microswitches. When the retracting lever is in a locking position, the bolt cannot be retracted within the lock housing. The cam is operated by a servo motor and locked in position by the gear train which includes a worm gear. The locking bolt may be a slam bolt having a spring biased latch which slides therewith or the locking bolt may be a deadbolt when the lock is used with a boltwork system of a vault door.
