Abstract
A high security padlock for use with a pair of companion locking bars having apertured hasp end portions to be disposed in aligned abutment and locked together, the padlock comprising a padlock body having a rearwardly opening cavity to receive the aligned abutting hasp end portions therein and the padlock including a shackle extending through said cavity to pass through a pair of aligned apertures in the hasp end portions, and a lock mechanism with the padlock body, together with a wedge attack resisting saddle wedge device shaped to surround three sides of the pair of aligned hasp end portions having a portion disposed in the rearwardly opening cavity of the lock body and portions protruding rearwardly beyond the rear surface of the lock body. The saddle wedge device has ramp surfaces along one side thereof coactive with inclined cam surfaces of the cavity to impart a component of lateral movement to the device when an attack wedge-like tool is driven against the rear of the lock body into engagement with rearwardly projecting end portions of the device and cause surfaces of the device and of the cavity to tightly grip the hasp end portions against withdrawal.
