lle it known that. I, WILLIAM 'L.`l 1snmn, n citizen ol. the United Stntesofesidinaf ntltlint, in the county of Genesee nnd Stole ol' Michigan, have invented certain new and useful lmproveniente in llydroezu'bondlnrners; nud l do hereby deeln-re the following to be n full, elem', nud exact description of the invention, .Such no will enable otherl skilled in the nrt; to which it nppertn-ins to multe :tud use the Home.

My invention roln'les to nn improvement in vapor-burners.

'lhe object is to provide n burner in which the Steam :1t :t high temperature may impinge upon a thin sheet. ot" oil in such n. nntnner :is to spread the mixed steam :rnd oil over en extended :ti-en, and thereby insure the complete C-,omlmstion o'l' the oil ond l'urnish :i llame ol' increased size :ind bent.

AA further object is to provide n burner of the above character in which the steam zuid oil may be regulated with ln-eeision and with greet, economy.

lVith these endol in view my invention consist-S in certain features oli etmSt-ruotion and combiinttion of parts, :is will be hereinafter described, sind pointed out in the claim.

In the accompanying' drznviugs, Figure l is n View ol the burner in longitudinl eentrnl section. Fig. 2 is :t cross-Section through line .rm ot' Fig. '1, und Fig'. Il is modification.

',lhe casing of the burner is preferably VFormed in three sections-wiz.,the Lsection A nt the end ot' the burner where the vapor is ignited, the middle sect-ion, l, ond the opposite end section, C. The menig-section A hns ite Central bore, ,enhtrged nl; its outer or discharge end, the prelerztble form being that Shown in l`ig'.l,\\'here the centrati boro is. lirst enlarged grznlunlly, forming' walls o' at an ongle. of about forty-live degrees tothe axis ol' the burner, :und subsequently enlzufged lds rapidly, forming walls a,whieh only diverge from the exis of the burner live degrees, (more or 1055,) and extend beyond the burner to l'orm :L dash, against which the oil and steam impinge. The opposite end of the Said easingseetion A. also has its bore enlarged, n. shown :it e, and provided with in niternzrl screwtthrenlhn, extending from its end nv Sufficient distance to lorm n secure joint between il :uid the Serew-tiueanled end l: oi' the .nimm-*tube l1", which connects the sections A and l to- `L ,'elhelz '.lhe bore ol' the middle neelion, :it its end townrd the section A mrrerq'ionl'ls in sis/.e with the cent1-nl portion oi` the. bore ol' section A; but it is enlurged :dong its middle portion lo l'orm :t stoom-ehnmiler, l1', sind nl its (.pposite end to receive the end ol the ensilnr-ncction t?. 'lhe end r ol' the nerliou t Alorins the mnle :ind the end l1 ol the section ll the lfemnle glnndol :i stelling-box about the oildube 1),:1ud the. two glands nre secured together through their interni [inneres Il nud r by suitnble bolts, r", ns is u.-=un.l. The eosing-noetion t? nenr ithI end lewnrd the seetion l is provided with nn enlarged bord/5", l'orining; an oil-chamber, nud ai short dintnnee'lroln the oll-elnunber if it is n un enlarged to reeeive the unile gland r" ol` :i stelling-box, l, the latter beine,` provided with nu internal serow-threaded portion, e, ndnpted lo be. Serewed onto the threaded end of the lubulnr portion ol the seetion t, as shown.

A skeleton section, r", in the present in- .Sl'tnee heart-shnpet'h connects the tubulnr portion ol' the section t` with the opposite end, f', of the said section, the hitter being; essentielly an intereally-Serow-thrended eolien'.

The, oil-lube l) exteiul` cent-really through the bores olf the several czming-5eclionn, nud is made Sullieientlv Smaller ihn-n the bore to lorm nu nnnulztr stemn-ehninber, lf, between il; and the interior wnlis ol' the mining. The slzuiling'dioxes :tbove rel'erret'l to tit tightly :tround the lube l), but permit it lo slide longitudinally through them. Along its portion which corresponde with the oil-chamber 1: the tube l) isprevuled with perforntions if] through its wnlln, which ndmit th-zx oil iulo it l'rom the elnunber. The latter is Supplied .from nnjv convenient source through n supply-pipe., S. (Shown in dotted lineel in ilig. l.) ',lhe end of the oil-tube toward the end of the easing; where the oil is ignited is provided with n tubulin.' vnlve, (l, which is Ylfnstened tothe end o'l the tube, prefere-bl)vv by menus el an intei-unl screw-thread, (7, which engages a. corresponding thrend on the end oli' the tube. The Stem of the vulve is Somewhat Smaller lhzin the bore ol.' the cosine-Hootie!i A lo per- IOC mit the passage of steam around it, and it is held in position centrally within the casingsection by"n1eansof wings or feathers Q', which project from its stem. The discharge end of the valve is Spread out to nearly till the enlarged end of the casing, and is shaped to conform with the walls a and a of the easing, so that when slid back from the end ot' the easing it may be made to seat firmly on the wall or valve-seat ct and shut o'i the escape of steam. The bore at the free end of the valve is enlarged, forming a Iiat conicalshaped opening, its walls forming a conical Valve-seat, y, for the oil-valve, as will hereinafter appear. The opposite end of the tube Dis fitted with an operating device as follows: A hand-wheel, II, has an extended hub, h, the bore et which is adapted to loosely receive the tube i), and the exterior of the'hub 1s provided with a screw-thread 7L', adapted to register with a screw-thread, h, on the interior of the end o of the casing-section C. The hand-wheel and its screw-threaded hub are secured on the tube D between a collar, d, and stuffing-box I, which screw onto the end of the tube. Thus as the hand-Wheel II is turned its hub h will travel longitudinally through the end e of the easing-section C, and Will carry with it the tube D and its valve G to regulate the discharge of steam around the free end of the valve. The stuffing-box I not only serves to hold the hand-wheel in place on the tube, but serves together with the Valve-rod as a closure for the end of the tube, and 1s provided with a stem, yz',having a central longitudinal perforation, i', through which the valve-rod for operating the valve extends.

The oil-valve I( has a 'flat outer face and a conical inner or under face, It, ii'tted to seat on the conical;V g of `the valve G. Its stem /c is smaller than the bore ot the valve (i, to admit a [low ol' oil around it, and it is centered within the stem of the valve G by means of wings or feathers k. The valvesteni le is secured to the end of the valve-rod 7s by a suitable coupling, r. The valve-rod where it passery through the stem 1' of the stuffing-box l is screw-threaded to register' with a corresponding screw-thread in the wall of the perforation i. The cap Loi" the stuitlng-box I screws onto the end of the stem i, and the valve-rod 7c" projects through the cap and is provided with a handle, ki, for turning` it. Thus as the valve-rod is turned the valve K will be moved away from or toward its seat and the discharge of oil regulated with the greatest precision. The length of the tube I) should be such that the valve G may be raised from its seat out of the end of the casing A to blow out any obstruction which may tend to clog the burner. The steam may be admitted to the steam-chamber IX through one or more steam es, l, and should be superheated betore entering the chamber. The

burner as thus constructed is capableot consnlming crude oil with the most favorable re suits, the superheated steam being eontinually under pressure around the oil-pipe, and thereby keeping the oil at a high temperature.

The arrangement of the valvesand casing section A is such that the oil as it escapes in a thin sheet outwardly toward the flaring Walls ot' the'easing will loe caught by the sheet of steam around the interior of the easing and spread oyera great area in a light vapor, which will insure perfect combustion and will aliord a great extent of llame. This is largely due to the course and direction given to the oil and steam by the discharge-open ings formed by the construction and arrangement of the different parts ol the burnerA The iiow et escaping steam is uninterrupted by eddies caused by portions et the steam impinging against other portions.` This is sought to be avoided, as such eddying would (aise retardation of the steam, and a greater or less deposit of oil upon the dash surround ing the steam and oil outlets would result, and, a consequent loss of effective work on the part of. the burner would necessarily follow. It will be seen that the discharge-passages ot both the steam and oil incline outwardly, and that one of the passages has a greater angle ot' inclination than the other, se that the two gradually approach each other.

The modification shows the walls a oi the Casin g about parallel withy the axis ot its here, instead of iiaring. This consti-notion gives fair results under certain conditions where a very great extent et' flame not nl material advantage; but the preferred l'orm i'or general application is that shown in Fig. 'I ,wllere tlnx walls d are slightly iiaring.

-I am aware that it is not new te make a vapor-burnerwith a steam-passage surround ing an oil-passage with an annular dischargepassage del'lecting the steam toward the axis of the burner, and such construction I do not claim; but

\Vhat I claim as new, and desire to secure py Letters latent, is-

In a vapor-liurner, the combination, with an outer easing having a portion olf its inner wall inclined outwardly to form a valve-seat and a portion outside ot said valve-seat at a different angle forming a dash, ot' a steam valve and an oil-valve within said easing and within the dash, one of said valves adapted to engage the valve-seat ot' said casing, the oil and steam passages adjacent to the poin t of discharge both inc-lining outwardly, and the inner passage having a greater angle oI inclination, whereby the two passages are made to approach each other.

In testimony whereolf I allix my signature in presence of two witnesses.
