Abstract : This patent discloses a torsion spring which longitudinally rotates a locking bolt when the bolt actuating linkages is severed. A woodruff key or the like is upstanding from a surface of the bolt. When the linkage is undamaged, the key slides with the bolt through a slot on the lock frame. When the bolt is rotated by the spring, it is locked in the rotated position by a locking pawl. In the rotated position, the key is out of registry with the slot and the bolt cannot be withdrawn from its extended, locking position. A second embodiment replaces the key with a recess in the bolt into which a locking pawl engages to prevent movement of the locking bolt.
