Abstract: A method and apparatus for a lockable, removable cassette for attachment to a bill validator is disclosed. The cassette is removed from a bill validator by service personnel and transported to a central office, where an authorized person unlocks a hinged door with a separate key to remove stored bills. A lever is turned to a predetermined position which unlocks the cassette from the bill validator, and locks a pusher plate to prevent unauthorized bill removal. The lever is prevented from being turned clockwise and from further rotation past the predetermined position. When the hinged door of the secured cassette is opened by authorized personnel, the lever is released from its locked position arming the cassette. The emptied cassette can now be returned to the service person who can now reconnect it to a bill validator by further rotating the lever, which locks the cassette in place and unlocks the pusher plate to prepare the cassette to receive bills accepted by the validator.

Abstract: Jam reducing apparatus for use in coin operated machines, such as telephones, acts to prevent the insertion of coins when the entryway is obstructed by foreign matter, assists in dislodging jammed coins and discourages vandals. The apparatus comprises a coin entryway which includes an inclined surface as part of a flared end of a lid. An entry slot in an entrance blocker, which is an integral part of the lid, as in substantial alignment with the coin insert slot of the front panel of the machine in normal operation. The lid is connected to a torsion spring and is associated with a coin reject lever. The inclined surface of the entryway lies opposite the blocker slot and is angled toward an exit of the coin entryway, which directs a coin into the machine. In normal use, inserted coins pass through the entryway and are directed into a coin mechanism for coin testing. Foreign matter inserted into the machine hits the inclined surface and exerts a camming force on the lid, rotating the lid about a torsion spring.

Abstract: A valve operator has a de-clutch mechanism for automatically shifting the clutch out of handwheel drive and into electric motor drive upon actuation of the electric motor. The motor drive sleeve 23 has an annular step 25 which has a flat 26. The clutch 50 is biased by spring 55 toward the motor drive sleeve 23 but is prevented from moving in the direction of the motor drive sleeve by the clutch fork 40 which has extending therefrom two latch arms 71,72 one of which 71 is longer than the other 72. The longer latch arm 71 abuts against the step 25 on the motor drive sleeve. When the electric motor M is energized, the motor drive sleeve rotates and the flat 26 comes into alignment first with the longer latch arm 71 and later with the shorter latch arm 72, thereby releasing in two steps the clutch fork 40 and allowing the clutch 50 to shift out of handwheel drive and into electric motor drive.
