ABSTRACT:
A mechanical dial combination lock for use in safes, file cabinets, security doors, vaults and warehouse doors. The disk type mechanical combination lock features a plurality of annular code discs, a base disc, a latch, an unlatching mechanism, a positioning mechanism, a dialing mechanism, a repositioning mechanism, a code-detecting mechanism, a casing and a dial. The dial combination lock is easily operated by persons familiar with conventional dial-face type combination locks, and yet is may be operated faster, and permits the combination code to be easily changed to any of a greater number of possible code combinations.
