ABSTRACT:
The improved safe door locking arrangement includes a pair of oppositely extending dovetail locking bolts. The locking bolts are eccentrically attached to a crank wheel and are actuated responsive to rotation of the wheel. The wheel is spring loaded for easier operation. In the extended or locked position, a combination lock controlled bolt locks the dovetail bolts in their extended condition. A further feature is a safety bolt which in turn locks the combination lock controlled bolt in the locking position, if attempts are made to dislodge the combination lock.
