VAPOR-BURNER.

To all whom it may concern:

Be it known that I, HERsoHEL M. CONNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, but at present temporarily residing at Tampa, Florida, have invented certain new and useful Improvements in Vapor- Burners, of which the following is a specification.

.My invention relates to hydrocarbon oil burners, and more especially to such a burner as will be especially adapted for, and capable of eificiently, burning kerosene, although it may beutilized in burning gasolene, or other hydrocarbons.

Heret-ofore there has been no satisfactory form of hydrocarbon burner adapted to use of kerosene as a fuel, because of objections due to the imperfect combustion of the oil resulting in disagreeable odor, and a deposit of residue from the partial combustion of the oil. I have found that such objections are due mainly to mechanical imperfections,

. which have preventeda proper vaporization of the oil and the proper mixture of the air with the vapor to insure substantially perfect combustion. By my invention I overcome these defects, and have produced a practical burner which satisfactorily utilizes kerosene as a fuel.

lVith the object indicated above in view, my invention consists in the novel construction and combination of parts, as hereinafter described, with reference to the accompanying drawings, and more particularly pointed out in the claims.

In thedrawings: Figure 1 is a bottom plan view of a burner embodying my invention; and Fig. 2 is a transverse section on the line 22, Fig. 1, with some of the parts in elevation.

Referring to the drawings, in which same reference characters designate the same or corresponding parts in both views, the numeral 1 indicates a part of the frame of the burner which is removably fitted in a hollow casting 7 provided with a number of threaded projections 2 aifording means for attaching the other parts of the frame and the piping thereto. The frame portion 1 is shown broken, but it is to be understood that said part may be extended as desired for attachment to a suitable bracket or other support, when used as a fixed burner struc- Specification of LettersPatent.

ture, or to a suitable standard forming part of a lamp structure when used as a portable lamp or burner.

Fitted in the threaded projections 2 are two pipes 3 extending laterally from the 1101- low casting .7, one of which is removably connected to a return bend 4:, communicating witha chamber inclosed by a casing 6, interposed between which casing and return bend is a smaller chamber inclosed by a casing 5 having lateral openings 25 communicating with the atmosphere, through which the air is drawn for mixture with the vapor as the latter is discharged into said air mixing chamber from the vapor generator. Extending downwardly from the burner casting areburner tubes 10, terminating in suitable burner tips, removably secured to corresponding threaded projections2 on said burner casting, each of which burner tips is provided with a wire gauze netting 26 suitably secured in place by a clamping ring 28. Two burner tips are shown, but it is obvious that either one or any convenient number may be used as desired. Secured to each burner tip is a mantle 11 of ordinary type, but in the form shown it is a common form of inverted ragmantle, though any other suit-able form may be used, according to conditions.

Extending transversely of the burner structure is a casting 15, having a suitable threadedprojection 24, to which is removably attached the outer end of one of the pipes 3, and another theraded projection 31 in which is removably secured a coupling 18, likewise attached to one end of a vapor generator tube 19, the otherend of which is preferably tapered and seated in a nozzle 30 having a contracted orifice 29 constituting the orifice tip, removably seated in the casing 6, which orifice is adapted to discharge vapor from said generator directly into the pipe or conduit I and into the current of incoming air, whereby a thorough mixture of the oxygen of said air and the kerosene vapor or other hydrocarbon vapor is efiected, The coupling 18, it will be noted, is pierced with a small passage communicating with the passage 16 in the structure 15 j and controlled by a needle valve 23 having a screw threaded stem 17 operated by a suitable handle. The passage 16, it will be observed, extends to the opposite end of the structure 15, and constitutes a feed passage for the oil to the burner. The supply of oil may be taken from a reservoir suitably located, from which it is fed through a wire tube 12 having its discharge end connected to the structure 15, in alinement with the feed passage 16, by means of a securing nipple 14, the flange of which is engaged by a collar 13 secured to the end of said structure 15.-

l/Vithin the casing 6 is a ring or cylinder 20 preferably of brass, removably seated therein, provided with a plurality of lines or rows of perforations 21, through which vapor from the vapor tubes or passages travels by way of a connecting nipple 8, such vapor entering, in fine streams or jets, the interior of the cylinder 20 through the perforations 21, and are there ignited within said cylinder, thus constituting a sub-flame chamber or heater for vaporizing the main fluid supply and fixing the said vapor. It will be observed that such vapor passes through the generator tube 19, located in the heating zone of the burners, in which it is vaporized initially, when the device is in operation, by heat from the mantle or mantles 11, the devices having been first put in operation by the application of the usual torch to the generator, and thence said vapor passes to the orifice end of the generator, and is then subjected to a second heat from the sub-flame in the sub-flame chamber 22, thereby further heating the vapor and discharging it, in best condition for mixture, at the point of admission of the air, from which point the mixture passes through the pipes 4; and 3 into the casting 7, thence through the opening 9 and into the burner tubes 10, where it is again subjected to heat from the mantles, and finally said vapor is discharged through the ends of the burner tubes, where it will be substantially perfectly burned.

In its passage through the generator 19, the oil and vapor are caused to pass into contact with or through an asbestos cylinder 27 wrapped around a rod 32, thereby preventing pulsations in the light, and also through a wire screen 33 in one end of the generator, thus preventing any remaining precipitate in the oil from reaching the burner tip. The last heating of the vapor before it is discharged from the burner tips prevents any possible odor from the oil, while the series of heatings in the manner defined contribute to' perfect combustion of the oil or vapor when finally discharged at the burner tip, because of the fact that the oil is first thoroughly vaporized and, in that state, intimately and uniformly associated with the oxygen of the air, in which condition it travels through conduits located in the heating zone of the burner at which it is ignited and burned. The wire gauze on the ends of the burner tubes performs the usual function of preventing flare backs.

By arranging the heater about the generator, and preferably in proximity to the outlet end of said generator, I find that the main fluid supply is not only efficiently vaporized but the vapor is fixed, so that the odor and residue are eliminated, thus obviating two serious objections encountered in the op-' eration of kerosene burners prior to my invention.

If desired, the cylinder 20 may be removed, thereby converting the apparatus into an eflicient burner for gasolene or like hydrocarbon, without any other change in structure.

While I have shown the preferable form of my invention, it will be understood that I do not limit myself to this form, or to the details thereof, as changes may be made in the specific form and details, without departing from the spirit of my invention as hereinafter claimed; for example, the superheating chamber may be arranged differently with respect to the generator, and two or more of such chambers employed, while alcohol or other vaporizable fluid may be used, where desirable. It is furthermore to be clearly understood that, while I refer to burner tips, mantles etc., such use of the plural number is merely for convenience, and not intended as a limitation, for it is obvious that one or more burner tips and one or more mantles etc. may be used without departing from the legitimate scope of the invention.
