  • Patent number: 4325240
    Abstract: Locking mechanism has both a key setting multiple tumblers to unique positions and a combination wheel for each tumbler so that opening of the lock requires setting each wheel to correspond to its tumbler position. For a single lock, different keys require different combinations. A mechanical recorder records the wheel positions with each lock opening so that all combinations used for access can be read, if necessary.
