ABSTRACT:
An apparatus for delivering natural gas or liquid propane under pressure from a fixed gas pipe source to a gas appliance mounted on casters and movable to and away from the fixed gas pipe source. The apparatus includes a connector, a unitary valve assembly member and in some instances, swivels. The unitary valve assembly member is directly connected to the fixed gas pipe source and includes a ball valve, a check valve, a quick disconnect coupling and an operating device for manually positioning the ball valve in an open or closed position. One variation of the unitary valve assembly member incorporates an operating device which prevents the quick disconnect coupling from being disconnected with the ball valve in an open position. The unitary valve assembly member may further include a temperature sensitive device incorporated within the check valve such that at a predetermined temperature the check valve will close in order to prevent ignition of the gas supply at elevated temperatures. The fixed gas pipe source can either be mounted on or extending from a wall or be mounted in a utility distribution system. The utility distribution system can take the form of an island configuration, a wall-mounted configuration, a ceiling-mounted configuration or a tray slide/counter configuration.
