VAIOR-GE NERATOB certain new and useful Improvements n Vapor-Generators, of which the folio 111 is a lull, clear, and exact description, rel-sluice being had to the accompanying drawings, formii'iga part hereof.

My invention has relation impro ements in vapongcncratois lor generati Q vapor from hydrocarbons used in lighti and heating or for other purposes; and consists in the novel details of constri more fully set forth in the specification Quilt pointed out in the claims.

In the drawings, Figure 1 is a front elevation 01' my invention morited over a gasolene-tank; Fig. is a horizontal section on line 2-2 oi Fig. 1; Fig. vertical tr 0 1s verse section on the line 33 of I Fig. 4 is an enlarged middle vertical sectional detail of the vapor generator and burner rounding the same.

The .0 eject of my invention is to construct a vapor-generator which will J'uply the vapor at the mint of consumption substantially a uniform pressure, so that rihere for example the vapor be used for ligh ng purposes, the flame shall not fluctuate but remain practically constant.

A further object is to construct generator which may be readily attached to a tank containing the hydrocarbon or gasolene to he vaporized; one which shall be compact, sim ple, and under ready control, and one possessing further and other advantages better apparent "from a detailed description of the invention which is as follows:

Referring to the drawings T, represents a tank provided with a pipe p leading to any source of compressed air supply (not shown). Projecting above the tank is a sleeve 1, the upper end of which is screwed to the lower open end of the generator chamber 2 ofmy improvement. Inserted into the sleeve 1 nd extending up against the root of the generator 2 is a wick-holder or tube 3, said tube extending below the surface of the gasolene in the tank and having upper terminal notches or ports 1 for the escape of the vapors into the chamber 2, or rather, into the space around the tube within the generator-chamber. Cast with the generator 2 is a preheat- Specification of Letters Patent.

ing basin 5, said basin having formed with it an extension 6 serving as a connection and support for the hollow tee .7 whose inner horizontal arm connects with the passage c formed in the needle-valve casing 8 cast with or otherwise secured to, the generator 2 (Fig. l). The vertical leg oi the tee 7 serves casing l'or the regulating necdle-valv 9, th iced need -Ialve 10 in the cash a a in used to turn on or cut oil the supply of vapor completely. The valve-stems are provided with operating handl s it as usual.

As vn in 3, the veitica leg through a tip 11 in o a end of which lwall of said niiXir thereinto a {lei-i with Silltl the mixin the she inixtu the uni-en v the riser pipe S'lltztlllB p Leadi 1 om the union 13 at a paint pposite the (llSolhLT O end the tune 1 31 is a shunt 16 which lends downward and dis "see into an annular lisurner 1. which rovided with a series of ii rner alone the inner wall of the 11 er turner, the lzases oi the tips 18 if as a ed mack- -"=urncr 17 loosely. encoiruasses the genera r hcing accurately held displacement when once in proper position, by lugs 20 cast on the ledge 21 which is formed jointly with the walls of the ch aniherQ and valve-casing 8.

To render the structure compact it udll be seen (Figs. 1 2) that the closed end of the mixing char er 12 tapers at the bottom so as to he brought close to the burner 17.

In the operation of the device, and assuming the same to mounted as shown in Fig. 1, the feed-valve 10 is first closed, and some alcohol or other hydrocarl: on is poured into the basin 5 and ignited. The flame thus heats the walls of the valve-casing and generator 2. The valve 10 is then opened, and the gasolene, forced both by pressure in the tank T and by capillary attraction of the wick I/V, finds its way to the generator 2 the union, wher and air dischar cc it conducted thro d to the uiiicnlte tion.

flashing into the burner. The

where itis vaporized by the heated walls, the vapors passing through the valve casing S, tee 7, tip 11 into the mixing chamber, drawing in the air after it (see arrows Fig. 1) and forming a mixture ready for any available consumption. A part of the mixture of gas and air becomes naturally shunted through the pipe 16 into the burner 17, and escapes through the burner-tips 18. This escaping vapor is now ignited, the flame permanently impinging against the walls of the generator 2 and vaporizing the gasolene as it rises through the tube 3 into the chamliier 2. The hot vapor thus mixing with the air supplies the riser 15 and may he used for lighting or heating purposes as desired. The valve 9 which may be termed the regulating valve is never completely closed, but is merely turned to position which will insure a predetermined delivery of the vapor into the mixing chamber.

The interposition of the wick between the generator and source of supply (tank T) serves to prevent any flicker in the flame due to variations of pressure in the tank, since the supply of hydrocarbon due to the capillary action of the wick is sufficient to prevent these variations being felt at the point of discharge of the gasolene into the generator; and since the presence of the wick insures a substantially uniform discharge, the flame will be constant. The wick therefore acts in the nature of a regulator and'controller of the supply of the hydrocarbon to the generator, whereby such supply becomes uniform under varying conditions of pressure in the tank T.

In lieu of a wick wire tubing'may be sub stituted for conducting and controlling the flow of the hydrocarbon from the source of supply to the generator. Where wire tubing is used the gasolene tank may be removed some distance from the generator, and outof harms way, it being practical to employ wire tubing of any length.

Having described my invention, what I claim is 1. In combination with a source of hydrocarbon supply, a vapor generator, means for l l l l 1 l conducting the hydrocarbon to generator, a mixing chamber communicatlng with the generator, a burner encompassing the,

upper terminal of the generator and located contiguous to the mixing chamber, means for shunting a portion of the gases from the mixing chamber to the burner, and means for regulating and controlling the rate of'delivery of the hydrocarbon to the generator, substantially as set forth.

2. In combination with a hydrocarbon supply tank, a generator chamber, a wicktube leading thereinto, a valve-casing communicating with said generator, a mixing chamber into which the valve-casing discharges, a regulating-valve for regulating the discharge of the vapor into the mixing chamber, a burner contiguous to the mixing chamber encompassing the upper end of the generator, means for conducting the mixture of air and vapor from the mixing chamber to a suitable point of consumption, and a shunt leading from a point beyond the 'mixing chamber for conducting a portion of the mixture to the burner, substantially as set forth.

3. In combination with a hydrocarbon supply pressure-tank, a wick-tube leading therefrom and projecting out of said tank, a sleeve encompassing said tube, a generator secured to the sleeve and receiving the hydrocarbon delivered by the wick in the tube, a needle-valve casing communicating with the generator, a mixing chamber, a valvecontrolled valve-casing communicating with the first mentioned valve-casing for regulating the flow of the vapor to the mixing chamber, a hollow union receiving the contents of the mixing chamber, an annular burner encompassing the generator, and a shunt lead ing from the union to the burner, substantially as set forth.

In testimony whereof I ailix my signature, in presence of two witnesses.
