ABSTRACT:
A lock having a counterweight connected through a lever to a spring-actuated lock bolt on a safe to balance out any inertial forces tending to move the bolt out of its locking position when the safe is struck a heavy blow. A latch forming a part of the lock latches the bolt in its locking position when an attempt is made to dislodge or destroy the lock case or a part thereof. A selectively usable bolt part is effective to change the lock from a deadbolt type to a slam-bolt type.
