TITLE OF THE INVENTION BOLT MECHANISMS ABSTRACT OF THE DISCLOSURE A bolt mechanism for the door of a safe has bolts which are thrown by a crank arm turned by a spindle connected to an external handle, the crank arm carrying a pin which runs in a drive slot in a bar connected to the bolt strap. A plate is carried by the bolt of a lock so that when the safe bolts are thrown and the lock operated the plate carries the crank pin clear of the drive slot, the crank arm being slidable transversely on the spindle for this purpose. This operation isolates the connecting bar from the spindle to prevent the application of force to the boltwork through the spindle in the sense tending to withdraw he boltwork.
