ABSTRACT:
To permit selective operation of a lock, by a key, upon insertion of a coin, or a master key, a release element projects into the path of a coin insertion channel, the release element being depressed upon insertion of a coin and permitting rotation of a lock cylinder; the lock cylinder carries, in addition to the locking bolt, a lever which, upon rotation thereof, moves the coin out of the path of the release element, and to a second position in line with the further path of the coin chute, so that, upon subsequent operation of the lock cylinder, the coin will drop through the chute. To permit operation by a master key, the release element engages an internal locking tumbler which can be independently moved by a master key, so that the lock can be operated without a coin, or if the coin chute is plugged.
