ABSTRACT:
A changeable safe deposit lock, usable in a single key or a double key configuration, having one or a pair of stacks of vertically slidable adjustable fences carried on a bolt plate and held in adjusted positions by a clamping assembly having a changing screw which is accessible at the back of the lock when the bolt plate is in unlocked position. After insertion of a key for which the lock is presently conditioned and rotation of the key to the unlocked condition, the screw may be loosened and the key rotated an additional distance whereby the initial key can be removed from the lock and a second key may be placed in the lock and rotated to return the bolt plate to the locked position and the changing screw tightened down to lock the fences in the new position adapted to the new key.
