Abstract
A changeable multiple key lock for safe deposit boxes and the like, including a locking bolt slidably movable in a lock case and having a pair of longitudinally spaced fence members, two stacks of peripherally gated tumbler wheels rotatably supported in the path of unlocking movement of the fence members having gating recesses to receive the fence members to permit bolt retraction to unlocking position, and two sets of key operable pivoted sector levers having gear teeth couplings with the two stacks of tumbler wheels to be operated by a guard key and a renter key. The two sets of sector levers are pivotally mounted eccentrically on posts which are rotatable to positions decoupling the levers from their associated tumbler wheels by a change key to free the sector levers to assume new positions for a new renter's key or a new guard key.
