ABSTRACT:
An exposed shackle padlock including a casing and a U-shaped shackle movable between an outer open position and an inner locked position. A fence plate is supported for rocking movement within the casing about a pivot lug between locking and unlocking relations with a notch in a shorter leg of the shackle. One or more peripherally gated rotatable tumbler wheel members adjacent a fence formation on the fence plate normally prevent its movement to the unlocking position and may form either a key operated locking mechanism or a dial operated combination locking mechanism. The tumbler members in the combination lock form are scrambled during opening movement of the shackle and the fence plate is displaceable relative to the pivot lug to permit return of the shackle to locked position.
