Abstract
A universal boltworks mechanism is compatible for use with any of a range of shapes and sizes of safe door and is alternatively enclosed in an easily fabricated centrally located bore on the interior surface of the safe door or in a pan enclosure which is easily welded to the interior of the safe door. The mechanism particularly includes a universal cam member which is configured such that it may be used without adaptation with any of said shapes and sizes of safe door alternatively driving three bolt driving structures of a first configuration on one side thereof and four bolt driving structures of a second configuration on the other side thereof. The universal boltworks mechanism is also provided with a bolt inhibitor which inhibits unlocking movement of each bolt whenever a breakaway portion of the mounting enclosure cover plate has been broken away in response to tampering forces in excess of a predetermined amount.
