HYDRoCARBoN-BURNER.

Applicaton led August '16, 1919. Serial No. 318,006.

To all whom t may concern Be it known thatv I, JAMES A. KEN- woRTHY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification. y

lfy invention relates to liquid fuel burners, and is particularly adapted to be used in the fire boxes of ordinary cooking stoves or in hot air or water furnaces.

One object of my invention is to provide a novel means for spreading the flame from the burner, in order that the heat units may be evenly distributed throughout a considerable area, as well as directing a portion of the flame and heat created thereby on the generator and mixing chamber, whereby-l the fuel may be thoroughly and efficiently vaporized.

Another object of my invention is to provide a means whereby the overflow and un- ,.consumed portion of the fuel oil may be caught and utilized for heating the generator preliminary to the starting of the burner.

A further object of my invention .is to.

provide a novel form of mixing chamber.

A still further object of my invention is to provide a means whereby the unconsumed portion of the fuel oil remaining in the generator and pipe leading thereto, may be withdrawn therefrom, and stored away for future use after the fuel supply to the burner has been shut off, thereby avoiding the waste of said fuel oil by evaporation, as well as avoiding the danger of unconsumed oil being generated into gas and forming carbon in the burner. ,v

I accomplish the above and other objects which will appear in the following description, by means of the burner illustrated in the accompanying drawings, in which:

Figure 1 is a vertical section through my complete burner, as it would appear when in use.

Fig. 2 is a transverse section taken on the 'line 2-2 of Fig. 1, viewed in the direo- I tion indicatedby the arrows.

Fig. 3 is a section taken on the line 3--3 of Fig. ,1.

Fig. 4 is a section through the burner and generator, showing a modified form of mixing chamber and llame spreader applied thereto.

Fig. 5 is a plan view of Fig. 4, parts which 4or furnace.

would s how in the distance being omitted for the sake of clearness.

Referring more specifically to the drawings, 10 designates the generator, adapted to be projected into vthe fire box of a stove or furnace, the front wall of which is illustrated at 11, which comprises a tube 12 provided with an upstanding elbow 13 at one end, and'has threaded into its opposite end a fuel pipe 14 which is adapted to extend outwardly to the exterior of the stove The elbow 13 is exteriorly of rectangular formation as shown in Fig. 3, and has resting on its top surface the burner head 15, which comprises a plate provided with a centrally disposed perforation 16.

A mixing chamber 17 is adapted to be supported directly above the burner head 15, and preferably comprises a tube 18 open at both ends, as at 19 and 20, and provided with a downwardly depending centrally disposed boss 21, having a rectangular opening 22,'which fits over the elbow 13, and rests upon the burner head 15, and is supported thereon by means of the shoulder 23, formed in the boss 21. An aperture 24v 'the aperture 24 and supported above said aperture, by means of standardsl 26 and 27 is the llame spreader 28, which comprises a dished shaped annular disk provided with a plurality of perforations 29.

Arranged in the bore -of the generator 10 is a coil of wire gauze or similar material 30, which serves to break up the fuel into minute particles and aid in the vaporizing of the same. f

The free end of the pipe 14 is threaded Ainto a T fitting 32 and the end of a piece of pipe 33 is threaded into said fitting opposite the pipe 14 and has threaded onto its outwardly extending end the needle valve shown) At right angles to the .pipes 14 and 13 andv between the same, a piece of pipe 41 is threaded into the fitting 32, the opposite end .of said pipe being threaded into the lower portion of a pump 42, said pump compris` 34, said 4valve comprising the valve stem lleading from a source of supply (not 'adaptedto receive the needle point 50 of the valve 51, said valve being adapted to open and close communication between the barrel 43 of the pump and the pipe 41, aS. clearly shown in Fig. 2 of the drawings.

Threaded into a boss 54 on the lower surface of the tube 12, is a iringfpan 55 arran ed below the generator and adapted to bev lled with oil in order that the generator may be heated preliminary'to' vstarting the burner.

In Figs. 4 'and 5 I have illustrated a modified form of mixing chamber and dame spreader and deiector, adapted to coperate with the same style of l tenerator and bur-ner head as illustrated in ig. 1. The mixing chamber 57 comprises a tubular structure' 58 provided with the bottom ,59 and the 'aredwall 60 at its top. vThe bottom 59 is provided with a boss 61, similar tothe boss 21 having .an opening adapted to fit over the burner-head in a similar manner to that illustrated in Fig. 1./ The bottom 59 is provided with the'aperture 62 adapted to register with the perforation 16 and with a plurality of openings 63, communicating with the atmosphere. Y

The wall of tube 58 is provided with a pair of oppositely disposed openings 65, arranged adjacent thebottom 59 adaptedv for `ghe admission of air into the mixing chamer.

. AThe top rim of the flared'portion of cham-l ber 57 is provided with a pluralityv of notches 67 i adapted to receive the 'projections 68 of a spreader plate 69, said spreader plate being of slightly smallerl diameter than. the diameter of the top of chamber 57; thus leaving van annular passage 70 for the passage of the flame.

In the operation of my burner, the burner head may be provided with legs or supports (not shown) sothat the burner maybe supported in the range or furnace inthe desired position. The valve 84 is then opened as shown in Fig.1, to admit the fuel to the generator, the valve 51 leadinl to the pump being at this time closed. he oil in the firing-pan 455 is then lighted to heat the generator to vaporize the fuel assing therethrough. -When sutlicient as has been generated a match is applie at the opening 25 of the preferred form or the passage 70 insane drawn in throu h the open ends 19 and 20 of the'mixing c amber 17 by the action Aof the gas and is mixed withfthe vaporized fuel.

valve' 34,'a certain amount of the ungenerated oil remains inthe generator and When the' burner 1s shut oli" by closing the i pipes 14 and 41, which would become wastedf and befoul the burnerand emit anoifensive odor. In order to conserve this oil andv prevent the odor therefrom, the valve seat` 49 is then opened and the' piston 44drawn upwardly, thus sucking all of the. surplus. oil up into the pump barrel and holdingl it there to 'be used in'rechargingthe generator when it is again desired to start' the burner.

In the modified form as illustrated in Fig.

4, the air enters the chamber 58 where it 1s mixe`d-with the gas issuing from the burner tip 16, the flame impinging against `the .plate 69,:is forced downwardly through. the

apertures 63 onto the generator, a portion of the flame passing through the annular passage 70 is spread into a large circular flame.

What I claim is: e e p 1. A gas generator construction, comprising a generator having a source of fuelsupplyleading thereto, means for controlling said fuel supply, and a suction mecha? nism interposed between said vgeneratorand fuel controlling means,whereby the unconsumed oil may be withdrawn from said generator.

2. A gas generator construction, comprising a generator having a fuel supply pipe leading thereto, a valve for controlling the supply of fuel through said pipe to said generator, 4a pump interposed between said generator and supply controlling valve, anda second valve adapted to open and close connection bet'ween said first mentioned valve and said generator..

In witness that I claim the foregoing I have hereunto subscribed my name this 7th p dayl of August, 1919.
