Abstract
Abstract A connector assembly for delivering natural gas or propane from a fixed pipe having a shut-off valve to a moveable gas cooking appliance on casters is provided in which a swivel is coupled with a connector which in turn is coupled between the shut-off valve and the gas appliance. The swivel maintains its shape and physical characteristics at least up to 800° F. temperature for at least ten minutes. The swivel has a first body member which has a first and second end. A nut is rotatably coupled to the first end of the first body member. The first body member is rotatable about a fixed first axis with respect to the nut which is coupled to the shut-off valve. The swivel has a second body member having a first and second end. The first end of the second body member is rotatably coupled to the second end of the first body member. The first end of the second body member is rotatable about a second axis which intersects the fixed first axis and is rotatable with respect to the fixed first axis. The second body member of the swivel having a third axis at the second end and adjacent to the fixed first axis rotatable about the fixed first axis and intersecting the second axis. A connector is coupled at one end to the second end of the second body member of the swivel. The other end of the connector is coupled to the gas cooking appliance.
