Abstract
513,074. Permutation locks. SCHULZ, O. E. March 30, 1938, No. 9713. Convention date, Jan. 27. [Class 44] In a lock having permutation discs 4, notched at 13 to permit projections 11 on a push-button shank 12 to enter, a disc-scattering mechanism is provided comprising a plate 15, slidable transversely with respect to the shank and moved by it against the action of a spring, during which movement pawls on the plate pass idly over ratchet wheels 31 fixed to the discs, but engage the wheels to scatter the discs during the return movement. The plate 15 is actuated by a wedge 19 on the shank 12 or the shank and plate may be connected by toothed gearing. The plate 15 may form the tail of a bolt 16 or the shank 12 may operate the ignition switch of an automobile. The pawls may be replaced by leaf springs having one end attached to the plate 15 and the other end free to engage the ratchet wheels.
