Abstract: A burner assembly has a ring generally centered on an axis and defining an array of outwardly open holes and a compartment at the axis. A gas/air mixture is fed to the ring to project jets of the mixture from the holes so that, when ignited, the jets form a main annular flame centered on the axis. A relatively small burner in the compartment is generally centered on the axis, and a horizontal plate on the ring overlies and covers the compartment and the burner. A gas/air mixture is supplied to the burner to the burner to form in the chamber underneath the plate a small flame centered on the axis. The cover plate is a generally circular disk having an outer diameter greater than an outer diameter of the small burner. The disk outer diameter is greater than an inner diameter of the ring.

Abstract: A gas stove burner has a base defining an axis and a ring assembly sitting on the base, forming therewith an annular outer compartment and a central inner compartment, and formed with an array of outwardly open lower passages open radially inward into the outer compartment. A generally imperforate cover disk overlying the ring assembly has an outer edge, upwardly closes the inner compartment, and forms with the ring assembly an array of upper passages open radially inward into the inner compartment and radially outward at the disk outer edge. Inlets on the base feed respective gas/air mixtures to the compartments and form a main flame at the edge from the mixture exiting the lower passages and a simmer flame at the edge from the mixture exiting the upper passages.

Abstract: A burner head for a gas burner which is preferably of an aluminum die casting body whose outer surfaces are provided with an enamel coating.

Abstract: A cooktop panel having a throughgoing main mounting hole and upper and lower faces has a burner having a holder underneath the panel, engaging the lower face at the hole, and provided with a gas inlet and a gas nozzle and a burner head mainly above the panel, engaging the upper face at the hole, and forming a downwardly extending intake passage into which the nozzle can feed gas. Fasteners engaged through the panel between the holder and the head retain the holder and head against the respective lower and upper faces. A burner cover atop the burner head forms therewith an annular gas-distribution chamber comunicating with the passage and forms with the burner head an annular array of outlet openings. This cover in formed with an upwardly projecting rack-centering collar defining a central seat. A rack atop the cover is formed centrally with a centering pin engaged in the seat. The holder is formed with a radially projecting mounting arm in turn formed with at least one vertically through-going igniter hole.

Abstract: A stove burner safety system has an electromagnetic valve and a manual gas cock controlling the gas flow to the burner and a spark plug adjacent the burner which receives a spark pulse from the electric circuitry which also controls an electromagnetic valve. When the stem of the manual valve is actuated a switch turns on the electric module and when a flame failure is detected a train of a certain number of spark pulses is supplied to the spark plug and if reignition does not occur within a certain number of pulse or a certain time, the electromagnetic valve is turned off.
