Be it known that I, Rosana W. LAwaoN, a

city and count of San Francisco and State of California, lave invented certain new and useful I'm rovernents in Hydrocarbon-Burners, of which the followin is a specification.

The hereinafter described invention" relates to an improved burner for the supplying of an atomized hydrocarbon mixture as ing of that type disclosed in United States L etters'Patent No. 1,020,612, granted unto me under date of March 12, 1912, wherein takes lacean-intermixture of oil, steam and air; t e object of the invention being to "produce abetter mixture of the-steam, air

.burner of Letters .Patent' I secure a com a'ct flame, to increase "the volume of the ame and intensity of the heat and oil than is obtained b the use of the thereof, to provide means whereby the flow of oil into the burner may be readily 1ncreased and decreased in accordance with the richness of the mixture desired, and to overcome the-carbonizing of the'working parts of the burner.

To com rehend the invention reference I should be ad to the accompanying sheet of drawings, wherein- Figure 1 is a vertical longitudlnal sectional view of the im roved burners. Fig.

2 is a detail View of t e nozzlezand its adjustable tip. Fig. 3 is a perspective view of the ejector tube for directing the mixturewithin the bonnet of the burner. Fig 4 is a front end elevation of the burner.

In the drawings, the numeral'l is used to designate a base preferably of spherical form, the interior of which constitutes an air induction chamber 2. From the said base outwardly extends diprojects ahonnet I 3, which when the burner is applied to a furnace projects within the firing chamber thereof. The bonnet 3is of tapering form, gradually enlarging toward the discharge end thereof, aud'to impart a fan shape to the flame projected therefrom the same is of elliiiticalshape in cross section. c

The base 1 is provided interior-1y with a rib or bridge 'piece 4 formed with a screw threaded bore 5, into which screws the exteriorly threaded tubular end section 6 of an ejector tube, which inner end of .said tube projccts into air induction chamber generally, the burner be- Zef the base 1 to within a 5116adram, of

Within the oil ,supply pipe is fitted an adjustable rod 11, which connects with the cone valve 12 seated the said rod 11 is moved longitudinally within the oil pipe 10 in order to adjust the .valve 12-! means ofthe adjusting hand wheel 13. 12 the nozzle outlet ,8, there; from .the nozzle 7 may trolled for securing the proper admixture of 'oil and steam and to regula e Qtlggintensity of the flame. r r; I

The base 1 isprovided with one or more air inlets 14, through which air is drawn into the chamber 2 for supplying the requisite oxygen to the mixture as drawn into the ejectortube, which mixture is forced underpressure into and through said tube for discharge bonnet 3. The suction created by the mixture flowing through theejector tube draws lets 14, such air as does not intermix with' the atomized carbonaceous mixture [lowing 3 through the passage-ways l5 formu'dhy the bridge-piece 4 for supplying the necessary oxygenfor proper com the air inlets 14 are coutrolled by the ad'- justable dampers 15', so that the quantity of air. drawn into thocluuulxar 2 may be regurtherewith the'outerjend section 6' of said I ;tra1 openingI or'outletj 8 which is gradually I The conicalfnozzlejsj.provided with a. rear- I f I in the flaring outlet 8 of the nozzle 7, and r V y means of the adaustable valve be ijclidily conignition-at the outer end thereof within the I air into the chamber 2 through the" air ininto the ejector tube passes into the .bonnet ustion.
