Abstract

Abstract A combination lock mechanism for locker doors and similar movable closures having a manually operable latching mechanism for the door, wherein the lock includes plural combination dial wheels spaced along a common axis and hubs which may be coupled with the dial wheels at different combination positions. A movable fence is normally restrained by the hubs in locking position to hold a locking bar against vertical movement and is released by gates in the hubs to permit the locking bar to be moved vertically to unlocking position when the correct combination is dialed. The locking bar is arranged to permit opening movement of the latching mechanism only when the fence is released upon dialing of the proper combination, or upon operation of a master key by a custodian which overrides the combination locking mechanism.
