HYDROCARBON-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 417,457, dated December 1'7, 1889 Application tiled February 29, 1888. Serial No. 265,655. (No model.) Y

To all whom' it may concern:

Be it known that I, WILLIAM WILSON, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hydrocarbon-B urners and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it -appertains to make and use the My invention is an improved lburner for hydrocarbon'oils.

The object of the invention is to provide a burner of simple and economical construction and adapt it to vaporize effectually hydrocarbon oils of any density. It is included in that class of burners in which the oil is vaporized by the heat of its own combustion; and the invention consists in the special construction, as hereinafter fully explained, and illustrated in the accompanying drawings, in which- Figure l is a vertical central section through the generatorl and burner. Fig. 2 is a perspective View of a part of the burner.

In the drawings the vaporizing-chamber A is represented of tubular form and may be made of a piece of iron pipe or cast with one end integral with the body. A cap a in the form shown is screwed onto and covers the upper end. A pipe B, formed on or inserted through the lower head b,`extends axially to near the upper end of the chamber. The upper end of the pipe is closed; but lateral openings c are provided in the pipe and near its end, just above an annular flange (l, which extends from the pipe horizontally into the chamber. This pipe Bis connected to any Suitable pipe D extending from a tank for the supply of the hydrocarbon to the chamber. Around the lower end of the vaporizingchamber is xed an annular upwardly-curved flange E, which forms with the wall of the chamber A an annular' trough or cup about the bottom of said chamber.

Within the oil-pipe B is a pipe H, which passes through the end of pipe B and opens into the chamber. The pipe H is smaller in external diameter than the interior diameter of the oil-pipe, so that an annular space is left for the flow of the oil. The pipe I-I leads to any suitable water, steam, air, or gas supply, and it and thepipe Behave suitable cocks for the regulation thesupply of oil or water.

Within the chamber Ais placed a filling 'of pipes M, leading from the bottom of the generator.

They are turned outward and upward and have suitable tips m. These tips are arranged in a circle about the generator. Over themis located the burner. It is mainly composed of two annular plates O P, one above the other, suitably supported in proper relation to each other and to the generator, substantially as shown. Over each ti-p is an opening in the lower plate, in which is placed a tube q, the lower end of which extends to the tips of the vapoiaducts and the' upper end into the space between the plates, but terminates a little below the upper plate, leaving a space for the flame or vapor to pass over the upper end of the tube. On the under surface of the upper plate P is a flange a', surrounding the upper end of the tube, caus-v ing a more perfect mixture of the vapor and air, and thereby more complete combustion.-

The plates are connected to form an annular combustion-chamber by means of perforated walls fr, and the said chamber surrounds the central chamber A. The tube q, the flange, and the walls may be circular, as shown in Fig. 3, or the tube and 'llange may be elongated or ot' oval shape. In either shape or of any cross-section the tube serves to draw in the air necessary for the complete combustion of the vapor. The same eect may be produced by having two concentric burners; but either will be sufficient when the generator is working to its fullest capacity. The upper plate becomes heated andin turn aids in the combustion of the vapor, which, rising through the tube, impinges against it.

ame from the circle of burners around the generator supplies heat thereto sufficient to produce constantly the required amount of va- IOO The

por. The annular ou p about the base of the generator serves in the form just described to hold an amount of the hydrocarbon to start the apparatus.

The annular combusiion-chamber, as shown in Fig. 1, is supported from the outer rim of the trough E by mea-ns of lugs v1, having depending fingers fitting the rim of the said trough, as shown. At suitable intervals openings are made through the upper and lower plates of the combustion-chamber by means of the pipes s, and through these pipes air may pass for aiding in the combustion, the air in this manner being directed between the inner and outer flames.

I do not limit myself to the use of steam produced in the generator. It may be generated elsewhere and forced through the inner pipe, or under some circumstances air may be used. This may be desirable in connection with some oils. A very small amount of air, gas, or steam, or a mixture of any of these, will produce, even from heavy oils, a very superior heating-vapor.

I claim as my inventiony l. In combination with the chamber A and its filling, a central oil-supply pipe B, burners leading from the chamber A, and a combustion-chamber consisting of the annular plates O P, having perforated sidewalls and openings in the bottom plate to the interior of the combustion-chamber, said openings being in line with the burners leading from the chamber A, substantially as described.

2. In combination with the chamberA and its filling, a central oil-pipe B, burners leading from the chamber A, a combustion-chamber consisting of the annular plates O P, having perforated side walls, tubular openings in the bottom plate in line with the tips of the burner, and tubular openings through both upper and lower plates for the passage of air, substantially as described.

3. In combination with the chamber A and its filling, the central oil-supply pipe B, burners leading from the chamber A, a combustion-chamber consisting of the annular plates O l), connected by perforated side walls, tubes exten ding through the chamber formed by the plates, tubes q, extending through the lower plate covering the tips of the burners, and a liange a', formed on the under face of the upper plate, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

lVILLIAM WILSON. 'itn esses:
