ABSTRACT:
A locking device has an elongated cylindrical member with a central bore, a shaft disposed in the bore including a transversely radial arm, the shaft being movable in the bore and manually grasped for combined rotational and axially slidable movement through a continuous but winding passageway in communication with the bore along its length. Preferably, the cylindrical member is defined by a plurality of annular disks in which individual circumferential slots are formed in each disk and are aligned to be in communication with one another throughout the length of the member to form the passageway and a locking member is disposed in the path of the arm so that engagement by the arm will cause the locking member to be advanced to an unlocked position with respect to another fixed member, such as, the wall of a safe.
