' Application filed September 7, 1907. Serial No. 391,760.

To all whom it mag concem:

Be it known that I, ROLLIN H. VVHITE,

a citizen of the United States, residing at 'Gleveland, in the county of Guyahoga and The invention consists in the construction,

combination and arrangement of parts hereinafter described and set forth definitely in the claim. I

In the drawing, Figurel is a bottom plan view of a hydro-carbon burner constructed according to the present invention. 'Fig. 2

s is an elevation thereof. Fig. 3 is a sectional sideview taken on line 3-3 of Fig. 5 of the outer end of the mixing tube and the pipe in which the jet openings are formed. Fig. 4. is a transverse sectional view of said mixing tube showing diagrammatically the arrangement of said jets relative to each other and to the mixing tube. Fig. 5 is a sectional Referring to the parts by letters, A is the burner shell which has an impervious bottom a, and suitable openings a through por through this mixing tube.

its top forthe escape of combustible mixture. It has a large mixing tube a, of cylindrical form, through which the mixture is discharged into the burner. The mixture consists of hydro-carbon vapor and air. Because the bottom of the burner is impervious, substantially no air to supply the combustion is furnished, save that which enters the burner with the hydrocarbon va- Just outside the end of the tube a, but close to it, is a multiple jet nozzle B. As each jet issues from a jet opening under pressure, it rapidly expands in diameter,said jet being in the form of a cone with the apex thereof at the jet opening. The surface of this conical jet, by friction upon the surrounding air, takes into the tube with it the air to support its combustion.

The principal difiicult-y which prior ex perimenters have'met in seeking to produce a high power hydro-carbon burner has been to get enough air into the burner to cause the complete combustion of'the hydro-carbon vapor. This result is attained by the construction herein shown and described, by so directing, and arranging the jet openings relatively to each other and to the wall of the mixing tube that'each jet will for'the longest possible time be continuedout of contact with the other jets and the mixing tube, and therefore completely surrounded by air. This end may be attained in the highest degree by making the jet openings substantially parallel with each other, and with the axis of the mixing tube and by arranging them in a circle around the axis of the mixing tube and at suchdistance therefrom that the enlarging jets will contact with each other ,and with the mixing tube in substantially the same. transverse plane. This arrangement and disposition of the jets is the underlyingprinci-ple of the invention, and is illustrated in Figs. 3 and 4 of the drawings. In Fig. 4 the small circles represent the jets, their centers being the axes of the jet openings which, as shown, are arranged around the axis of the mixing tube.

The fuel is supplied to the jet nozzle B in a vaporized condition. This previous vaporization may be accomplished in any desired mannerv I am aware that multiple jets for a hydro-carbon burner are not new; and that burners have been produced in which a plurality of jets are severally discharged into as many mixing tubes. This construction is expensive compared with that being described; is impractical for use on automobiles, because the jets and mixing tubes are, some of them, necessarily placed in inaccessible positions; and moreover, the construction does not give very satisfactory results.

I am also aware that several ets have been projected into the same mixin tube;

but in those cases the jets have been irected toward each other so as to cause them to I. quickly .1ntersect,- upon the theory-that thereby the vapor streams and air drawn in thereby would be more thoroughly mixed.

" purpose for which the present invention is 3 bottom, vapor openings in its top, and a mixing tube connected with its side, with a front of the mixing tube and substantially coaxial therewith, said pipe coil having in the face which is toward the end of the mixing tube a plurality of jet openings, the axes of which are substantially parallel with the axis of the mixing tube.

In testimony whereof, I hereunto aiiix my signature in the presence of two witnesses.

Perhaps this result is attained'by the construction refererd to, but it by 'so much ret duces the volume of air drawn in by the jets,-and. consequently defeats the very designed.
