ABSTRACT:
A coin operated lock includes a casing with collection box and a locking mechanism which is operated by a key. A coin in a receiving pocket of a sliding carriage, connects parts of the mechansim and allows a bolt to be reciprocated upon the rotation of a key. Normally, a spring-biased pawl with ratchet blocks movement of the bolt unless a coin link connection is established that enables the carriage to ride over the ratchet. Upon locking, the key can be removed and the ratchet locks the carriage in extended locked position. Upon turning the key from a locked condition, the pawl is guided to release the carriage and allow return of the carriage with bolt to an unlocked state. The pocket can be adjusted to accommodate any size coin or token. The coin falls by gravity from the pocket to the box which can be locked or latched. The entire device can be easily mounted on the front of most lockers to provide at least minimum security.
