Abstract
Abstract A cable-type lock assembly in the form of an indestructible elongated armored cable having a loop-forming lock housing at one end through which the other end of the cable may be passed so that the lock housing functions as an overlap slip joint and provides a closed retaining loop. By progressively pulling the cable through the locking housing, the loop may be shrunk to a required size while a key operated cylinder lock which is associated with the lock housing functions to retain the latter at selected positions along the free end region of the cable and establish the position of the overlap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
224 words
A lock assembly comprising, in combination, an elongated flexible stranded, steel cable having a fixed end and a free end, a lock housing member secured to said fixed end, an end member secured to said free end, a series of tubular sheathe-like armor sections threadedly received over said cable and bridging the distance between said lock housing and end members, means establishing a ball and socket joint between adjacent armor sections to allow limited flexing of the cable accompanied by corresponding angular displacement between adjacent armor sections, a helical compression spring disposed within one of said members, encircling the cable, and effectively bearing at one end against the cable and at its other end against said one member so as to place the cable under tension and draw adjacent armor sections hard against each other, said lock housing member being formed with a transverse bore therein adapted slidingly to receive therethrough the free end region of the cable together with the adjacent encompassing armor sections in order thereby to produce a closed variable size loop, and releasable key-actuated locking means carried by said lock housing member and including a locking part movable into and out of selective locking engagement with such armor sections as encompass the free end region of the cable when one or more such sections are disposed within said transverse bore.
Claim 2
Dependent Claim

A lock assembly comprising, in combination, an elongated flexible stranded, steel cable having a fixed end and a free end, a lock housing member secured to said fixed end, an end member secured to said free end, a series of tubular sheathe-like armor sections threadedly received over said cable and bridging the distance between said lock housing and end members, means establishing a ball and socket joint between adjacent armor sections to allow limited flexing of the cable accompanied by corresponding angular displacement between adjacent armor sections, a helical compression spring disposed within one of said members, encircling the cable, and effectively bearing at one end against the cable and at its other end against said one member so as to place the cable under tension and draw adjacent armor sections hard against each other, said lock housing member being formed with a transverse bore therein adapted slidingly to receive therethrough the free end region of the cable together with the adjacent encompassing armor sections in order thereby to produce a closed variable size loop, and releasable key-actuated locking means carried by said lock housing member and including a locking part movable into and out of selective locking engagement with such armor sections as encompass the free end region of the cable when one or more such sections are disposed within said transverse bore.
Claim 3
Dependent Claim
20 words
A lock assembly as set forth in claim 1 and wherein said compression spring is disposed within said end member.
Claim 4
Dependent Claim
39 words
A lock assembly as set forth in claim 1 and wherein each socket element presents a generally cylindrical outer surface having a diameter which is approximately equal to the diameter of the transverse bore in said lock housing member.
Claim 5
Dependent Claim
91 words
A lock assembly as set forth in claim 3 and wherein the depth of said socket-like bearing surfaces is less than the radius of said convex bearing surfaces so that the ball elements serve to maintain the opposed rims of the socket elements in spaced relation to establish an annular void therebetween, and the key-actuateD locking means includes a cylinder lock in which said locking bolt is slidable between a locking position wherein it projects selectively into said voids, and an unlocked position wherein it is withdrawn into the cylinder lock.
Claim 6
Dependent Claim
56 words
A lock assembly as set forth in claim 4 and wherein said locking bolt is slidable in the lock cylinder radially of the cable and the forward end of the bolt is formed with a locking flange which presents a concave relief area for enhancing the extent of projection of the flange into said annular grooves.
Claim 7
Dependent Claim
64 words
A lock assembly as set forth in claim 1 and wherein said lock housing member is formed with a first reduced counterbore and a second further reduced counterbore, the fixed end of the cable projects through said second counterbore and extends into the first counterbore, and there is a retaining ferrule fixedly secured to said fixed end of the cable within said first counterbore.
Claim 8
Dependent Claim
99 words
A lock assembly as set forth in claim 6 and wherein said end member is provided with an internal chamber having a cable opening leading thereto, the free end of the cable projects slidingly through said cable opening and into said internal chamber, a second ferrule is fixedly secured to said free end of the cable within the chamber, and said helical compression spring surrounds the free end of the cable and bears at one end against the ferrule and at its other end against the rim region of the cable opening to thus place the cable under tension.
