Abstract: A shielded lock assembly incorporating a housing surrounding a shackle and lock body. The housing renders more difficult access to the shackle and lock body in order to reduce the incidence of theft involving the prying, cutting or other destruction of the shackle or lock body. In one embodiment of the invention the shielded lock assembly is adapted to receive a pair of cable ends. In a modified embodiment of the invention the lock assembly is adapted to be positioned adjacent a planar surface such as defined by a pair of doors or the like. In a still further modified form of the invention, the lock assembly is adapted to be positioned adjacent intersecting planar surfaces such as defined by a door and a jamb.

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.

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.

Abstract: A hasp which by its potential for bending in certain vital areas, and by its permitting an attached padlock to swivel freely, will tend to frustrate those methods usually relied upon to defeat the standard hasp-padlock protective mechanism.

Abstract: A locking arrangement for clamping a watthour meter to an assembly includes first and second locking members each having first end portions which engage an annular ridge of the watthour housing, offset portions which engage an annular ridge of the adapter housing and second ends which are secured to the adapter housing from a rearward surface of the adapter housing to make removal of the watthour meter from the adapter assembly more difficult.
