GASOLENE-BURNER.

Specification of Letters Patent. Patented Juil@ 20, 1911.

vApplication filed June 27, 1910. Serial No. 569,114.

To all whom 'it may concern.:

lie it known that l, ALBERT S. FREEMAN. a citizen of the United States, residing at Alexandria, in the county otl Madison and State oflndiana, have invented a new and useful (iaSolene-Burner, of which the following is a specitication.

The object of my invention is to produce an apparatus, more especially designed for ready attachment to existing hot water ree.-

ervoirs, by meansl of which water may be heated by gas producedby the apparatus from a supply of gasolenetor other ein'iilar volatile fuel.

The accompanying drawings illustrate my invention.

Figure l is an elevation in partial vertical section of my improved generatorI and heater; Fig. 2 an elevation at right angles to Z0 that, shown in Fig. l and with the inclosing casing omitted, and Fig. 3 an elevation ot' the complete apparatus associated with the water reservoir. y

In the drawings, l() indicates a flat thin hollow body or heating chamber within which may be maintained a comparatively thin body ot' water. Leading into the bottom of the heating chamber l() is an inlet pipe, ll and leading from` theI top of said chamber a discharge pipe l2. rl`he pipe ll'is adapted for connection with the lower region otf the water rcservoir lZ-i and the pipe l2 is adapted for connection with the upper regions oi' .said reservoir. 'l`be upper end of the body l() is provided with a linger or bracket l-l to which l .secure a hollow crosshead l5 provided with oppositcly extending down-turned branches lo, lt, and a ccntral upward receiving branch IT into which i.s

40 secured the lower end otl a mixture pipe t8. Secured to Ieach branch lo and depending therefrom alongside ot a tlat face ot the main body l() is a gas pipe 1S) provided with a plurality of laterale 2t which extend toward the adjacent tlat face of body 1t).

` Secured to the, outer end of each olf the laterale 2l is a suitable, burner nipple or nozzle 22, so arranged as to direct the burning upon the adjacent flat tace ot body 1.0.

Secured to the upper end ot' pipe i8 is a tubular cap23 provided with a central mix ing tube 2li into the open upper end of which is directed a nozzle 25 in which is mounted an ordinary controlling needle l turn.

valve ope ated by a head 26 Secured thereto. .l-lead 2o provided with a depending` linger I' adapted to engage a lateral 25', forming part of the nozzle 25, so as to limit the movef ment of the head 2G to about one complete 60 Nozzle 25 is integral with superheater tube 2S) which is Supported in an ex tension 23 of the cap 23. The Superheater tube 2t) extends alongside of the mixture tube 1S and at ita lower end it is connected 65 by a suitable coupling il with Aa generator or vaporizing pipe 32. The pipe 232 extends for a short distance do\\' 1nvardly from the lower end of the supcrheater tube il along' side one llat face ol' body l() and passes 70 from thence upwardlyvto a couplingl 33 by means of which it mayl attaehed to a valve body Bl in which is mounted `a .suitable con.- trolling valve il?) by mean-L of which the tlow of gasoleue lo pipe 32 may be controlled. 75 Leading into the valve body lisa suitable supply pipe :it which may be connected to any suitable source ot' fuel Supply, as for instance the ordinary pressure tank 37.

rl`he entire generator and heater structure may bereadily incased by a tubular casing 1li) sleeved down over the ystructure and supportcd upon cap 'li as cl url v shown in l*`ig. l uml as indicated b v dotted lines in Fig. Il.

Leading upward trom the hollow head l5 85 is asmall pipe 4l to thc upper end ot' which is attached a suitable burner t2 which is directed toward the .supcrluatcr tubo lil and the mixture tube i8.

rl`he operation is as lfollows: To start the e apparatus, nozzle 25 is lirst heated by any suitable means7 such lor instance as an ordi* nan' gasolene torch. When the nozzle 25 has been properly heated valve 35 and the valve controlled by head Qt are opened aud lgasolcne (lows from head S4 down through pipe 32, thence upwardly through the superheater pipe 2t) and nozzle Q5 where it is vaporized and passes Jfrom thence through mixture. tube v1% and from thence, through theI branches lt' to pipo lt) and emerges through the burners Q2 against. the flat faces of the heater body lt). Atthe same time a portion of this gas rises from the head 'l5 through tube 4t to the burner 42 and is lighted7 whereupon the flame 'from this burner 42 envclops the Supcrhtulter tube. 2t) and the mixture. tube t8.

l have found from practice that it is desi 'able to heat 'the gasolene feed tube at a charge therefrom to the mixer because otherwise the volatilized fuel is not suliicicntly het to properly mix with the air. I also iind that it is desirable that the mixture of gas' and air be also thoroughly heated before it'- reaches the burners, as by that means I am able to secure a proper noirexplosive mixture of gasolene vapor and air which, because of its high heat, will burn with prac-` tically a colorless llame against the water cooled walls et' the heater body 10.

"1y the arrangement shown I am enabled to practically entirely envelop the water heater body l0 and, because ot' the thinness ot the column ot water in the body, to heat the said column almost instantaneously. By turning head 2G in closing direction until linger 2T engages lateral 25, the nozzle valve is brought to a point where just a sutlicient amount ot' gas will emerge to maintain the burner l2 in generating condition, while by turning the head 2G in the opposite direction to its l'ull amount the maximum supply o' gas is obtained.

It will be readily understood that the geir erato`r described herein may be used in connection with other forms ot' heaters.

'lhc particailar -l'orm of heater shown is readily attachable to existing watertjanks which are now commonly found either in connection with water backs of coal burning ranges or provided with heaters of various kinds capable of burning illuminating lt will be noticed that, in the arrangement I have shown, the gasolene is vaporized in the tube 32 because that tube passes down alongside the heater body l() and comes within the influence of the flames ironi the' adjacent burners The gasolene vapor thus'produced in the tube 32 expands into the larger superheat'er tube 2t) where it is Supcrheated by the burner d2. It is also to be noticed that, by reason of this heating ot gasolene vapor, I am able todischarge the vapor through a downwardly, presented nozzle thus making it possible to bring the nozzle valve and the gasolene Ivalve 35 to the upper part of the structure where they can be readily manipulated. Thetstructure however is of such character that it will work satisfactorily in any position of direction of the nozzle 2 I claim. as my invention' i l. The combination of a mixture tube, two burner nozzles leading from the mixture tube, a vaporizing tube carried through the heat-ing zone of one ,of said burner nozzles, a superheating tube receiving the discharge from the vaporizing tube and carried through the heating zone of the other of said burner nozzles, and anozzle receiving the discharge from said superheating tube and d ischarging into the mixture tube, the initial portion of the mixture tube alsolying in the heating zone of one of said burner nozzles.

2. A vapor burner comprising a mixture tube, a. super-heater arranged alongside the mixture tube, a nozzle leading from the super-heater tube and directed in to the mixture tube a. valve for controlling the outflow from said nozzle, a vaporizing tube leading to the super-heater tube, a burner nozzle leading from the mixture tubd and having a heating zone through which the vaporizing tube passes, and a second burner' nozzle leading from the mixture tube andidirected toward the super-heater tube-and initial end of the mixture tube whereby said super`` heater tube and initial end of the mixture tube will lie in the heating zone of said second burner. Y

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana.
