Abstract: A safety pressure release locking gas cap is shown. The gas cap is comprised of a handle element, and a plug element. The plug element is rotatably housed in the handle element, and has external threads. A lock element is contained between the handle element and the plug element and can be used to lock the two components together. Locking arises by rotation of the lock element, for example by a key, about an axis of rotation which is a first manner of movement. The lock element has also a second manner of movement, which is axially along the axis of rotation. Movement in the second manner moves a valve from a pressure containing position to a pressure relief position. According to the present invention the movement in the first manner occurs independently from movement in the second manner.

Abstract: A protective housing and latch mechanism for securing the protective housing in a position protecting the customary housing for a coin mechanism and coin box. The protective housing permits normal operation of the coin mechanism and is of sufficient strength to resist deformation by sledge hammer blows. The protective housing carries a latch mechanism which locks the protective housing to the original housing for the coin mechanism so as to prevent separation of the two housings. The latch mechanism includes a pivotally mounted latch member which is urged to a latching position and held in that position by a barrel type lock which is disposed in an inaccessible position within a hardened block.

Abstract: A threaded cap for sealing an automotive vehicle fuel tank is provided with a unitary molded central plastic core and a bonnet rotatably mounted on the plastic core. A pair of concentric races are defined on the plastic core. The inner race carries a unitary molded plastic frame which has a pair of resilient, closely spaced transverse cantilevered arms defining a gap therebetween. The frame is also provided with a resilient catch. A unitary molded plastic bolt is reciprocally movable along the gap to engage and disengage the core for rotation with the bonnet. The bolt has two detents which coact with the catch on the frame to hold the bolt at selected unlocking and locking dispositions of movement. The bolt includes a stud which projects into the gap between the arms so that the arms spring bias the bolt toward the locking disposition. A lock mechanism is used to shift the bolt to an unlocking disposition so that the fuel cap be disengaged from the fuel tank inlet pipe.
