To LEZ wz/cmit may concern:

Be it known that l, JAMES S. GRAY, of New York, in the county of New York and State ci' New York, have invented certain new and useful Improvements Iin SeltGenerating 'Vapor-Burners, of which the following is a full, 'clear-,and exact description, reference being had to the accompanying drawings, which make part of this specification, and in 'whch- Figure l represents a. View in elevation of one side of a self-generating vaponbnrner embracing my improvements; and Fig. 2, verticai longitudinal section through the same, a portion of the burner being shown in section..

Mv invention relates to that class of burners in `which the niet' is situated at a distance from the reservoir which contains the luid, in order to guard against the danger ol' explosions, and is adapted more especially for' burning coal-oil, naphtha, and other Similar -ilnidsc In the accompanying drawings, which represent a convenient arrznigeinent of parte for carrying ont the objects 01" my invention, the supply-pipe A is shown as provided with a stop-eock, n., to controlv the flow of the fluid. it has also a wich-tube, l, screwed' intor it, which tube is partly filled with cotton Wick or other suitable and wl-,llknown equivalent material. An lunitifxg` dish, C, enen-cles the lower part ol the tubo, while a lnacket ornib, 2Q', is attached near ils uppei` end. A chan'- l lnel, fel, leads from the upperl part of the wickubedoujn through the bracket tol its lower end, Where it terminates in anjet, d', which open-1 into the lower end oi'a niicing'tlilioflil, which is securedl to or formspart of the bracket, and terminates in a 4immer-tip, e. Anv adjustiiig-screw, l1, 4serv/es -to regulate the size oi' the aperture in the mixing-tube.

A honte-.fusain (l, which projects over the burner-tip, is mounted upona stein, H, .which screws into the upper end of the wicktnbe,-

. and is provided with a conducting-rod, 1,.

which entends down to the wick. By unscrewing the supply-pipe Av and stem H access can.

readily be had 4to the several parts to cleanse them. .oth the channel d and jet d canin like :manner readily be cleansed by removing the screw-plug d2 in the bottom of the bracket and inserting asmall Wire.

.The operation of the earner as `follows:

As the vapor only is 'burnedl in this class of, lamps, and not the fluid itself, and as but lit- 'z tlc, if any, evaporation takes place when .the 'parte are cold, it becomes necessary to heat them before the burner Willignite. This is,

usually done by pouring a small qua'utityof alcohol into the dish C and inaming it. .The

stop-cock a is then tnrnedso as to permit the fluid to rise up into the wick-tube B from the reservoir, which is usually placed above-the "level of the burner. As thetiuid rises' through the Wickb,it is vaporized,passes down throng;

the channel d and escapesthrough the je Byrreference to' Fig. 2 of the drawings `it will` beseen that thefjet is inclined at sueh'an an .gie that the' vapor escaping from it impinges. directly upon the back or" the niixing-tubell, by which means-the hissing noise usuallyvv at? tendant upon the escape of vapor from burn- .ers of this class isavoided. As thev vapor es capes frointhe jet, it is mixed with air, which rushes in at the open' bottom of the tube 12,

'and then escapes through the burner-tipje,- where it is ignited. In order to vary the ret ative proportions oi' air and vapor escaping through the tip, I insert a set-screw or sorew plug, F, into the mixing-tube'above the jet d. Bymoving this screw in or outthe space left for the passage of vapor and-airy is correspondingly increased or diminished; and as the ,volume of vapor escaping from the jet may practically be considered invariable, `and as it I is driven into the mixing-tube Witha velocity due tothe. pressure of the 'gas generated be vhind. it in the wick-tube, it-i'ollows that as the screw F is intrnded into the -mixingtube the quantity of air admitted is diminishedand vice, versa, which is a great advantage in adapting burners of this lkind to thovarying conditions under which they arewrgeqgdiredto operate. The flame froni they bunuel?!tipl quickly warms' the cap G, the heat from which is conveyed by the stem Hl and eonducti-ng- 'ron i', to nicciuic. in themen-tube, which' is Athereby va] o1-ized and driven ont; thronghthc y' jet into the mixing-tube. f This process of selfgeneration continues as long as the lamp is heated. When the stop-'cock c 'is shut, the flame is not immediately extinguishedf but continues to burn until the fluid in the wick tube is all vaporized and that vapor exhausted.

.Having thus fully describedthe construction .nd operation'of'my improved Se]f-generati'n'gt operating as described, forthe purpose ofyeg 'opor-burner, what I claim as my il1vention, A latmg the relative proportions of alrand vn ,nd desire to secure by Letters Patent, ispor admitted to the borner-tiges set'rfortb.
