Abstract: A method of manufacturing a burner cap for a gas range includes the steps of providing an amount of non-porous aluminum and forming the aluminum into the shape of a burner cap such that the non-porous nature of the aluminum is maintained. In one embodiment, the non-porous aluminum is a slug at ambient temperature which is placed in a die and slowly forced into a die by an advancing a ram to form the burner cap. In another embodiment, the non-porous aluminum slug is machined to form the burner cap.

Abstract: An integral gas burner manifold and pressure regulator with an inlet fitting received through one wall of the manifold and threadedly engaging in the manifold a regulator body received through a second oppositely disposed wall of the manifold. The body has a valve seat and downstream ports for supplying the interior of the manifold. Portions of the body extending exteriorly of the manifold, retain and seal a housing shell having a pressure responsive diaphragm exposed to the pressure of the ports. A poppet is disposed on the valve seat and is connected to the diaphragm by a rod; and, the poppet is moved by the rod in response to changes in pressure acting on the diaphragm. The diaphragm is preloaded by an adjustable spring.

Abstract: A gaseous fuel burner with a base formed of cast aluminum and a wafer cooperating with the base for forming an annular of flame generating ports. A cap is received over the wafer and forms a dead air space for reducing the temperature rise of the cap. The wafer and base are formed of aluminum or brass and the cap is either formed of cast iron or cast aluminum with a porcelainized steel disc insert on the upper surface.
