Abstract

512,678. Permutation locks. CARAVINO, E. FALLA-. March 5, 1938, No. 6984. [Class 44] In a permutation lock having notched rings 16 co-operating with teeth 13 on a shaft 12, the parts are assembled on a tubular member 4 which has a longitudinal slot for the teeth 13, a retaining collar 4' for the rings and a plate 2 by which the lock is attached to its support 10. The collar 4<1> carries a handle 19 by which the tubular member 4, and hence the shaft 12, can be turned, a pinion 20 on the shaft 12 meshing, in the unlocked position shown, with a rack 21 on the bolt 22. To lock the bolt, the combination is formed, the shaft 12 pushed in against the action of a spring until the teeth 13 have passed through the notches in the rings, and the combination then scattered. The permutation rings 16 are provided with setting rings 17 rotatable on them for changing the combination. The rings 17 bear code letters or carry pointers moving over a fixed scale. The invention may be applied to the ignition switch of an automobile, the shaft 12 operating the switch on axial displacement.
