ABSTRACT:
An armored cable-type lock assembly embodying an armored cable consisting of a length of stranded steel cable on which there are threaded in bead-like fashion armor pieces in the form of alternately arranged ball members and socket members. A fixed terminal lock housing at the proximate end of the cable is provided with a transverse bore through which the distal end of the cable may be passed so that the housing functions as an overlap slip joint and causes the cable to form a closed retaining loop when the distal end of the cable is in the bore, the size of such loop being regulated by pulling or pushing the cable through the housing. A key-operated cylinder lock which is associated with the housing has a locking bolt which, when projected into its locked position, engages the opposed ends of a pair of adjacent socket members and forces them downwardly against the bottom wall of the bore, the latter being recessed in wide angle V-fashion so that the captured or bolt-engaged part of the armored cable develops a kink within the bore and is thus locked against endwise sliding through the bore. A fitting at the distal end of the armored cable is in the form of a thimble having a recessed inner end that mates with a half-ball which is integral with a special terminal armor piece. Both terminal arrangements are such that the possibility of hacksaw or abrasive attempts to penetrate the armor is inhibited.
