Abstract
A high security hasp-enshrouding lock for securing together a pair of companion locking bars having adjacent apertured hasp portions projecting outwardly in parallel abutment, the lock having a lock body providing with a rearwardly opening cavity to receive the alined abutting hasp portions therein shielded over most of their extent by the lock body and having a shackle bar on a pivoted shackle lever movable transversely through the cavity and hasp apertures to lock the hasp portions against withdrawal. The locking mechanism within the lock body includes a pivoted hasp clamping member along one side of the cavity having a rear portion projecting from the lock body to intercept wedge type attack tools during attempts to wedge the lock from the schackle and having a contact surface defining a side portion of the cavity. The schackle lever is moved between locked and unlocked conditions by a cylindrical actuating member movable between raised and lowered positions and having a key lock plug therein and locking pin means coactive with the housing to lock and release the cylindrical actuating member. The contact surface of the hasp clamping member is rotated toward the hasp portions to clamp them tightly against the opposite wall portion of the cavity when the hasp clamping member is moved by wedge type attack tools.
