5 Claims.

'I'his invention relates generally to lighter constructions for gas ranges and refers more particularly to ash lighter constructions for the gas burners of stoves and ranges.

Heretofore in an endeavor to insure proper relation of the lighter to the burners the lighter tubes have been combined or formed integral with enameled burner trays, and the combined trays and lighters have been received within the burner compartments of the ranges between the pans at the bottom of said compartments and the grates at the top thereof. However, in use such combinations are impractical, primarily because the trays become too hot for the enamel thereon and cause it to crack and chip oi. Moreover, the constructions have been such that the burners themselves become hotter than usual due to the chimney eiect for air produced by the burner tray and lighter combinations about the burners, and such conditions result in objectionable popping noises when the supply of gas to the ignited burners is cut E,

Therefore, it is an object of the present invention to provide a lighter construction that is not only separate from and free of the burner tray, but is constructed and arranged in such a way relative to the burners and trays that the latter may retain their enamel finish, and the objectionable popping noises referred to will be substantially dispensed with.

Another object of the invention is to provide a lighter construction which enables the burner tray to be readily removed for cleaning or other purposes and affords the proper access to the burners to permit them to be cleaned, repaired or replaced as desired.

Another object is to provide a lighter construction which preferably includes a number of auxiliary burners which are constructed and arranged in such a way that they may be alternatively used as simmeri g burners and as lighters for the main burners.

Another object is to provide a lighter construction wherein the auxiliary burners are adapted to cooperate with the main burners to provide heat for cooking purposes.

Another object is to provide a lighter construction that is combined with the burner compartment bottom or pan which is rigid with the framework of the range so that the lighter will always be ini` proper position.

Another object is to provide a lighter construction wherein the pan just mentioned not o nly carries the lighter parts, but also serves .gas range having a lighter construction embodying our invention;

Figurel 11 is a cross sectional view taken on the line H II of Figure 2.

Referring now to the drawings, A is a gas range having a cooking top frame B, and a burner supporting pan C within and supported from said frame. Preferably the bottom I and sides 2 of this pan C are formed from a single sheet of metal and are located a predetermined distance below the top of the ame B. 'I'he pan C is preferably provided with an upstandlng marginal ange 3 that is rigid with the frame B. The bottom l of the pan C is provided at the center thereof with an opening 4 and is,

provided adjacent its four corners with suitable openings 5 for the reception of main burners D, while the sides 2 of the compartment have stepped ledges or shoulders 6 and 1 respectively upon which a suitable grate E and an enameled burner tray F are removably supported.

H is a pilot burnerhousing suspended from the bottom l of the pan C about the central opening and I are'tubes extending radially from said housing H to points beneath the burners D. Preferably these tubes I are formed by providing the bottom I of the pan with: inverted channel-shape portion I0 and by securing to the underside of said bottom a sheet metal spider or plate J having cooperating channel-shape portions I|. the housing H and upstanding flange ing 4. Preferably said cap I2 has' a plurality'f vents I4 therein. I5 is a substantially frusto.- conical ange extending upwardly from the edges of an opening I6 in the spider J.

K is a pilot burner within the housing H supported upon and adapted to receive gas from the stem 28 of an inverted T-shape fitting L. As shown, the burner K is within and terminates just below the upper edges of a frusto-conical shield 2l within the housing H, and openings 22 for air are provided in the sides of the housing below the upper edges of the shield 2| whereby the pilot burner K will make a Bunsem flame which will extend upwardly through the opening I6 to a point slightly above the upper edges of the frusta-conical flange I5. The stem of the fitting L extends downwardly through a plate 23 fastened to the bottom 24 of the housing H and is fastened to said plate by a suitable nut 25. The base 26 of the fitting is substantially parallel to the plate 23 and is provided with an inlet 21 for gas and a manually operable needle valve 28 for regulating the passage of gas through said inlet.

M are auxiliary burners fastened by nuts 30 to arms 3| of the spider beneath and in vertical alignment with central openings 32 in the main burners. As shown, these auxiliary burners M are provided at their upper ends with vertical jets 33 from which dames may extend upwardly and into the openings 32 in the main burners, and are provided at one side with horizontal jets 34 that are in alignment with and open into the outer ends of the tubes I. Preferably each auxiliary burner M has a depending mixing chamber 35 provided in one side with an inlet 36 for air and provided in its lower end with an interiorly threaded portion 31 receiving the exteriorly threaded portion 38 of a gas jet 39. A rotatable spring steel sleeve 40 having an opening 4| registrable with the air inlet 36 and having an operating tab 42 is preferably employed for controlling the air inlet 36, while a needle valve 44 having a stem 45 threadedly engaging the lower portion 46 of the gas jet 39 is preferably used to control the flow of gas from the inlet 41 in one side thereof to the mixing chamber 35. As shown, the lower end of the stem 45 extends below the lower portion 46 of the jet so that it may be readily operated and is normally concealed by a suitable cup-shape cap or cover 48.

The main burners D correspond to those set forth in our application filed August 6, 1934, bearing Serial No. 738,753. Preferably each burner has a sheet metal shell 50 containing a suitable diaphragm 5| and having a plurality of jets 52 in the top 53 thereof. The shells 50 are supported by ilanges 54 which rest upon the bases 55 of L-shape tongues 56 depending from the bottom of the burner compartment, and by posts 58 which extend downwardly from the shells and engage suitable holes 59 in the spider arms 3|.

In the present instance gas is supplied to the burners K, M and D, respectively, from a suitable manifold N in front of the burner compartment C. As shown, a pipe 60 extends from the manifold N to the base 26 of the T-ftting L. No valve is provided between the manifold N and fitting L for regulating the flow of gas. Hence, the supply of gas to the burner K is under the control of the valve 28 in the fitting L. However, the supply is preferablyA sleeved upon an l2 is an inverted cup-shape cap for l l the control of valves As shown, n vided with an inlet 66 and two outlets 61 and 68, respectively. Arotary plug 69within the casing 65 I3 at the edges of the Vopenof gas to the burners M and D is preferably under O mounted on the manifold each valve O hasl a casing. Drohas an inverted L- hape passage 19 for 'establishing communication between the inlet 66 and outlet 61; and` has a transversely 1| therein for establishing communication between an inlet by-pass 12 and the outlet 68. Normally the plug 69 cuts off the supply of gas from the inlet 66 to the outlets 61 and 68. Upon being turned from closed position, the slot 1| in the plug extending narrow .slot

will first open communication between the inlet by-pass 12 and the outlet 68. Subsequently while communication is still open between the inlet 66 and the outlet 68, the passage 10 and the plug will establish communication with the outlet 61. Thus, gas may be cut off from both outlets 61 and 68; may be supplied to the outlet 68 alone;

and finally may be supplied to both outlets 61 and 68.

are tubes leading from the outlets 61 of the valves to the mixing tubes 8| of the main burners, while 82 are tubes leading from the outlets 68 of the valves to the inlets 41 of the gas jets 39. Preferably the tubes 80 are supported by hangers 83 depending from the bottom I of the pan and are provided within the mixing tubes 8| with conical ends 84 and gas apertures 85. Nipples 86 of conventional configuration are adjustably mounted on the conical ends 84 of said tubes for regulating the flow of gas from the'tubes to the mixing tubes 8| of the burners.

In use, the flow of gas from the manifold N to the pilot burner K is regulated by the valve 28. Normally the valves O are closed. However, upon opening said valves O, gas will initially flow to the auxiliary burners M where it will flow through both jets 33 and 34. Owing to the pressure of the mixed air`and gas in the mixing chambers 35, the mixture discharged from the jets 34 will ilow through the tube I to the Bunsen flame of the pilot burner K where it will be ignited. The resulting flames will ash back through the tubes I to the auxiliary burners M and willv ignite the mixture discharged from the jets 33. If the valves O are left in the initial open position with only the slots 1| connecting the inlet 66 and outlet 68, the auxiliary burners M will be used as simmering burners as the flames therefrom will extend upwardly through the central openings 32 in the main burners to function in such manner. However, if the valves O are opened further so that the passages'18 establish communication between the inlets 66 and outlets 61, then gas will flow to the main burners D and upon flowing through the jets 53 will be ignited by the flame from the auxiliary burners M. If the valves O are left in fully open position, gas will flow to the auxiliary and main burners M and D, respectively, for cooking purposes.

Actually the flames from the auxiliary burners M are substantially shielded by the main burners D and associated lighter parts. However, if the flames from the auxiliary burners M are extinguished accidentally while functioning for simmering purposes, for instance by being blown out, the mixture from the jets 33 will again be ignited by the ignited mixture from the jets 34. Likewise, if the main burners D should be extinguished accidentally, the mixture from the jets 53 would be ignited by the flames from the auxiliary burners M. Thus, either or both bum- 2.
