Abstract
A high security padlock for use with a pair of companion locking bars having apertured hasp end portions to be disposed in alined abutment and locked together, the padlock comprising a padlock body having a rearwardly opening cavity to receive the alined abutting hasp end portions therein and the padlock including a shackle extending through said cavity to pass through a pair of alined apertures in the hasp end portions, and a lock mechanism with the padlock body, together with wedge-attack-resisting wedge members flanking opposite sides of the pair of alined hasp end portions each having a front portion disposed in the rearwardly opening cavity of the lock body and rear portions protruding rearwardly beyond the rear surface of the lock body. The wedge members have shaped surfaces coactive with surfaces of the cavity to impart a component of lateral movement to the wedge members when an attack wedge-like tool is driven against the rear of the lock body into engagement with the rearwardly projecting end portions and cause surfaces of the wedge members to tightly grip the hasp end portions against withdrawal.
