Abstract: A surface cooking appliance having a unique rotatable burner. The surface cooking appliance includes a top surface having a first opening and wherein a gas supply tube is provided having a terminal end adjacent the first opening. An igniter is mounted to the top surface adjacent the first opening. A burner is supported on the top surface above the first opening. The burner includes an inlet port, off-set from the center point of the burner, for receiving gas from the gas supply tube. The burner further includes at least two igniter openings for receiving the igniter such that the burner may be rotated about the terminal end of the gas supply tube and positioned in a plurality of positions wherein the igniter is disposed in one of the at least two openings.

Abstract: A turntable equipped with a gas pipeline includes a hopper having a passage along its axis adapted to receive one end of a gas pipeline and gas supply pipeline. The other end of the gas pipeline is connected to a gas stove through a turntable. When the turntable is rotating, the gas pipeline will rotate simultaneously therewith. Three O-rings located on the end of the gas pipeline extending into the hopper prevent gas from leaking therefrom.

Abstract: A cooking grill assembly of high energy efficiency is disclosed. A gas burner arm heat source is oscillated through an arc of a variable amount in order to limit the heat source cooperation with the cooking grill to that area of the grill on which the food is to be cooked. A means to limit the heat source to this given area of the grill is provided and includes a motor, drive linkage, and variable stop means so that the arc of the burner tube oscillation is limited to the selected area. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
