ABSTRACT:
A cable lock has a key-removable core of figure-8 shape mounted in a two-lobe axial chamber at one end of a lock body. The key plug of the core drives a rotary bolt mounted in a blind extension of one chamber lobe. The bolt releasably locks one cable end member inserted in a blind axial bore at the other end of the body, which bore is parallel with and overlaps the extension and lies opposite the second lobe of the core chamber. The other end member of the cable is inserted in a transverse blind bore located axially between the second chamber lobe and the axial cable-receiving bore, and is secured by a retaining pin inserted through the core chamber and concealed by the core in such chamber. In one modification, insertion of the releasable cable end member requires key actuation of the core. In a second modification, the rotary bolt has a rotatable cam head biased to locking position but formed with a cam surface so arranged that the head is rotated to a cable-receiving position when the releasable cable end member is thrust against it in the cable-receiving bore.
