  • Patent number: 5181402
    Abstract: A cable lock assembly for the bundling of lengths of material such as logs includes a lock affixed to a first end of a cable. One of a number of buttons rigidly affixed to the cable at a second end thereof may be placed is a complementarily shaped socket in a base of the lock. The button may be retained in the socket by a cover which is rotatably connected to the base and may be releasably secured thereto in its button retaining closed position. The cable lock assembly of the present invention is easy to handle without the requirement of specific tools and is reusable, thus reducing operating costs. Slipping of the cable through the lock in the closed position of the cover is substantially prevented, thus improving the reliability of the cable lock assembly.
