HYDBOCARBON-FUEL BURNER.

Application led November 5, 1919. Serial No. 335.914.

To all whom it may concern.'

Be it known that I, TnoMAs E. lVonTH nvu'roN, a citizen of the United States, residing at vKansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in llydrocarbon-Fuel Burners; and I do declare thc following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accom panying drawings, l.1nd to the letters and figures of reference marked thereon, which form a part of this specification.

This in vcntion relates to hydrocarbon fuel burners and one of the objects thereof is to provide a fuel burner in which the hydrocarbon will become thoroughly gasified so that complete combustion will take place.

I have provided means whereby the liquid hydrocarbon fuel may be preliminarily heated, if desired, to faporize it, the vapor being fed downwardly7 upon a surface, the heat from which will gasify the vapor and means is provided for supplying the requisite amount of oxygen to support combustion so that a very intense flame is provided, and where found desirable, l may utilize a heatretaining block, preferably consisting of asbestos or mineral wool on account of its known heat absorption and retaining quali ties.

In the drawings,

Figure I is a perspective view of a furnace to which my invention is applied, parts being broken away to show the position of the heater, and

Fig. 1I is a disassociated view of the several parts of the heater, and

Fig. III is a vertical, longitudinal sectional view through the heater.

Referring now to the drawings by numerals of reference:

1 designates a concavo-convex chamber having a central, upwardly extendinof, pyramidal or conical projection 2 an( provided With a cover 3 with a central opening 4, through which .the projection 2' slightly extends. The member 1 is provided with a plurality of air ports 5 consisting of downwardly projecting tubes and saidtubes discharge into a central` space 6 formed by a cover 7 resting upon the member 1, conneted to and sniced from the cover 3, as clearly indicate in Fig. III. The cover 7 Specification of Letters Patent.

preferably carries a scat or pan S to receive a heat-retaining block 9 of asbestos or simi lar material and through which the discharge end lll of the hydrocarbon supply pipe 1l projects, the discharge end l() being in axial alinement with the projection 2 and the supply pipe 1l having one or more coils 12 in close proximity to the burner cover T so that th(l heat therefrom will partially vaporize the hydrocarbon as it pa through the pipc and allow it to bo discharged in a vapor upon the (ll-.Hector plat@l formed by the projection there being a baille or ring-lil e iiangc 1S within the concavo convex member l to retard the pasu sage of the oil beyond. the base of the proV jectionV 2 but in `the event that enough oil enters the chamber formed by the members 1 and 3, this will be taken care of by the overflow pipe 14.

From the foregoing it will be apparent that if the valve 15 is opened to admit oil to the inner chamber burner and the same ignited, the burner will become heated. there being enough oil or hydrocarbon liquid re tained by the ring 13 for priming purposes. W hen the heater becomes hot enough, the hydrocarbon passing through the coil 12 will be vaporizcd and will be further gasi fied upon striking the projection 2 and in-A asmuch as there will be an ample supply of oxygen admitted through the ports 5, an efficient hydrocarbon mixture will be provided to supply an intense heat, as has been clearly demonstrated in actual practice. The arrangement shown in the drawings is such that practically no smoke or soot forms, as the combustion of the fuel is practically7 perfect and substantially all of the 1". T. Il. in the fuel are generated into heat available from the burner.

What I claim and desire to secure by Letters-Patent is:

1. In an oil burner comprising a concave bottom having a central, opstanding, conical projection, a bafile ring about the projection, the bottom being provided with air openings, a spider-like top fitting over the bottom and having air ports alining with the air openings, and an oil supply pipe extending through the top of the burner.

2. A burner comprising a base having an upstanding projection, a ring about the projection, said base being provided with openin s, a chamber above the base and havin tubular ports alining with the ports in the
