BURNER.

Application filed December 15, 1927. I Serial No. 240,190.

This invention relates toimprovements in gasolene burners, and the pr mary ob ect 18 to provide a lighter for starting the burner that is so constructed that the heat from a match is suflicientfor starting it, after which the lighter will continue to burn until the main generator is suiliciently heated for supplyin gasolene vapor for the main burner.

A iurtherobject of, the invention-is to -provide an especially constructed mixing tube for the vapor from the lighter generator so that the mixing tube, after thesame isstarted',

by the heat of a match, will provide heat for the lighter generator and also for'the main generator until the latter is jsuflieiently heatgasolene vapor for the main burner.

Other further objects, novel features of construction and improved results of the invention will appear from the following description and accompanying drawings.

In the drawings: F'gure 1 is a top plan view of the burner embodying the present invention.

Figure 2 is a vertical sectional viewof the lighter-generator and its mixing-tube adapted to operate in the ,manner hereinafter described.

Referring now to the" drawings, -in a preferred embodimentof the invent on is Y illustrated, A designates a burner, B the main generator, C'the match lighter gen erating tube, 1) the copper plate mounted upon .the matoh lighter generating tube, E

' the mixing tube ofthe lighter'fand F the main gasolinesupply pipe or. conduit.

Referring tothe drawings in more detail and ,describing ,the invention more specifi The present invention pertains to a special: construction of the cally, it will be seenthat the burner A is prov ded with a burner cap 5 having thereon a plurality of raised burner orifices 6. This. burner cap is surmounted u'ponand closes the burner chamber 7 through which chambor extends a ra sed housing 8 beneath which extends the main generator B. yThe extreme inner end 9 of the generator, which is in ref alltv a nozzle, is in communicationwith the.

end 10 of the conduit 11 which conduit in turn communicates witha second conduit 12, one end13 of which, is in communication with the burner chamber 7 andco fiveys thereto the gas from the in ain'. generator for the burner A.

Although only one burner is illustrated in a the drawings it will be readily realized that other burners can be operated from the: sin

glegenerator B by attaching them to, the opposite end-of the conduit 12. t

with the burner chamber 7 by reason or theplurality of slots or. orifices 1 1 which are placed in the top of the passageway.

Intermediate its length the passageway 8 is provided with an opening15 having a circumferentialfiange or collar 16. The burner,

cap 5 is provided centrally with an'opening 17 positioned to register with the opening 15 of the passagewaywhile the under. side of the burner cap is provided with a downwardly extending circumferential flange 18 around I the central opening 17 and this flange abuts the flangeflG. The flange 18 is offset from the edge of the opening 17 so thatwhen the burner cap in place it rests directly upon the upper end of the flange 16 as appears at 19.

The. lighter mixing tube which is designated by E, is attached to the bottom ofthe burner chamber 7 by a suitable bracket20 and bolts 21. "Ou elend oit'this mixing; tube E is of anfopen'bellshapeas appears at; 22. A

portion 28v of the mixing tube. parallelsthe bottom of the burner immediately below the 'rn ain generating tube B while the opposite end 24sof the mixing tube extends outwardly and downwardly;beyond the burnerbottom.

shield; has an open bottom 27.

pipe or fitting 30. The lighter generating tube is made of steel and extends from the litng 3O inwardly beneath the bottom of the en d 29 of the mixing tube E, the inner end 31 of the tube being in front of and slightly separated from the open end 22 of the mixing tube. The inner end 31 of the tube passes through a suitable opening 32 in a shield 33 which is attached to the mixing tube E as at 3%. This shield 331is so shaped as to partially close the open inner end of the shield as clearly appears in Figure 2 of the drawings.

'Attached to the lighter generating tube G by any suitable means is a copper plate D, which plate is positioned to be immediately below the orifices 28 in the lower face otthe outwardly extending end 24 of the mixing tube E and also incidentally below the open lower end of the shield 25.

The generator tube carries a valve 25 which is controlled through the wing nut 36. p

The admission of gasoline to the main generator tube B through the main conduit F is constant but the main generator tube is pro vided with a valve stem 37 the nmer end 38 of which closes theor fices in the nozzle 9.

This valve is operated through a suitable knob 39.

It has been previously pointed out that a portion 23 of the mixing tube E parallels the bottom of the burner chamber beneath the main generating tube. "This portion of the mixing tube is provided with outlet burner orifices 41.

Attention is directed to the fact that the copper plate D is provided with aplurality of holes 40.

Operation Considering the burner illustrated in the drawings with the valves in the positions illustrated, in operating the burner a match is held under the copper plate D attached to the lighter generating tube C. This match is held beneath the plate and tube for approxiiately: fteenseeonds and heats both of these The wing nut 36 is then rotated to open the generating tube valve which allows the gas which has been generated ,in the tube by reason of the heat from the matchto enter the open bell shaped end 22 of the lighter mixing tube E. This gas burnsthrough the burner orifices 41 in the mixing tube beneath the main generator tube B and heats the main generator tube. A portion of the gas in the mixing tube E also escapes from the orifices 28 in'the i as is the case the lighter generator tube C and keeps this tube hot as long as it is necessary to keep the lighter in operation.

After about one minutesoperation of this lighter the main generating tube B has been heated sutiiciently to generate gas for the operation of the main burner. The Valve 38 of the main generator B is then opened by rotating the knob 39 and the gas in the generator escapes through the nozzle 9 into the end 10 of the conduit l1. The passage through the end 10 of the takes with it a certain amount of air through the opening 42 in the end 10 of this conduit. The gas in the conduit l1 of course fed to the burner chamber 7 and also to the burner chambers oi" any other burners by the conduit 12.

The gas upon entering the burner chamber 7 passes upwardly through theburner cap orifices 6 where it can be ignited :tor the operation of the main burner.

There is also what might be termed a subfire inthe mainburner chamber. The gas in this chamber also burns downwardly through the orifices 14: againstthe main generator tube B to keep this tube constantly hot for the generation of gas so long as the main burner in operation. f

After the'ni ain burner isin operation the operation of the lighter is discontinuedby Lighter.

Attention is particularly directed to the fact that the lighter generating tube is made of steel rather than of brass, copper, or nont'errous metal. It has been found through experimentation that a steel tube is better in use for the reason that the steel tube withstands the operating temperature better than do brass, copper or non-ferrous metal tubes. I have also additionally discovered that a steel tube not as subject to the action of sulphur and other impurities'in the gasoline with the tube made of softer metal. I

Experimentation has further shown that thecarbon which is necessarily formed, in a burner of "thistube 'doesnot adhere to the steel tube as readily as it does to one made of non-ferrous metal. The lessening oi the car bon depositsis of course a material advantage.

"It is thought thatit will be readily apparent that the purpose of the copper plate I) is to absorb heat from the match and conduct it to the tube C so that the two will reach the necessary starting temperature very quickly. I V

-The only valvesin'the devices are those for the" lighter and in themain generator. Gasoline will be at all times present in both the main generator tube and the lighter generator tube. WVith the construction which'has been described it will be seenthat the lighter and the main generator are feed pipe delivers the gasoline to both. single delivery pipe for both the main genera-tor and the lighter generator has a decided advantage from a manufacturing stand point. v
