Abstract

184,763. Douglas, J. Aug. 16, 1921, [Convention date]. Keys.-A key is constructed to indicate automatically whether it was last used for locking or unlocking. The key is made with one part 5 of the shank fitting into a hollow part 6 and connected thereto by the pin P on the part 5 working in a curved slot 1 in the part 6. When the key is inserted and turned, the part 6 first turns independently of the part 5, bringing the pin P to one end O of the slot 1 if the key is further turned for unlocking, or to the other end S, if further turned for locking. The curvature of the slot 1, and the spring 2 pressing on the end of the part 6, retain the pin at the end of the slot until the lock is again operated.
