This invention/relates to new and useful improvements in a burner. I

-Onei objectof thetinventlon is to provide alburner ofthe'character described specially 5 designed for the .utilization of either oil or gas as'a fuel and: of such novel construction that it will readily vaporize the oil,

whenioil is used as .aifuel.

Another object of theinvention is to provide a iburner ,of :the. character described equipped-with; novel means for supplying air whereby a proper mixture of Iair and fuel may beat all times maintained to induce combustion of the fuel. y A further feature of the invention isto providea-i burner of: the character described equipped with a detachable combustion ring which will assist in the breaking up and completecombustion of the fuel used;

.A still further ifeature ofthe invention is toprovideialburner of the character described whichfis ofsimple construction and can be cheaply and easily manufactured and readily taken apart {for cleaning and is economical and eificient in use.

With the above and other objects in view this invention has particular relation to certain novelcfeatu'res of constructiomoperation andarrangementof parts, an example of which isgiven in this specification and illustrated in the accompanying drawing wherein [The figure shows aperspective view of the burner, partly in section.

Referring now more particularlyto the drawingthe-numeral 1 designates a stand which :is supported by the legs 2 an'dwhich includes an upstanding tube 8 into which the ,fuel supply line .4 is connected; There is a cup shaped support- 5 screwed on tothe upper end of the tube 3 and which encloses an air chamber GJThecentral vpart of the bottomof this. support is elevated, as at 7, forming a surrounding channel 8 provided to receive any drippings of oil and the fuel collecting in this channel ,may be drained out throughthe drainpipe 9. Supported by the upperiend offithe support 5 there is an annular base IO-having spaced'outer and innenupstanding'fianges 11 and 12 forming an annular channel 13 between them. Mounted on the base'vand detachable thereffromthere is anannular outwardly flared combustionring 14:. The base has acentral spider consistingaof radial arms 15 which.

are formed integrally with the baseand which are also formed integrally with; and

support a the central downwardly} elongated bearing 16. The fuel'line 4:, has the. upward tubular extension 4 whose y lower end "is threaded into the bottom of the support? 5' and whose upper endwextendsthroughthe.

bearing16 and" has a generator 17 screwed on to the upper end thereof and spaced above the baseflO. 'vThis'generator is conicalin general contour and has .an 1nternal'chamber 18 with an outlet 19 at the apex "of the generator and the outer surface of the generator is formed with aplurality of annular grooves 20, therearound. There is a generatorcapv21 whose upper side is convex and whose underside is formed to conform to the external contour of the generator and this capis fitted overthe generator and is held spaced therefrom by suitable spacing lugs, as 22. The 'fuel'passes into the chamber :18 through theinlet line 4, 4;" and'is partially heated therein and then'passes' up through'the outlet 19 and flows down over the surface of'the generatorin a'filmbetween the generator and flgeneratorcap and is held by the grooves 20, so that it will be thoroughly heated and vaporized in passing over the 'hot generator and will be discharged in'the form of ;a vapor into the channel 13where combustion takes place. The film will be deflected outwardly against the combustion ring by the rim of the cap 21 and said ring will-become very hot and further break up the unconsumed particles of gas so that'the fuel will be completely consinned.

The numeral 23 line whichleads to the usualfpilot burner whichmay be utilized in casegas is used as a fuel.

In case oil is used as a fuel it will trickle down around the generatorand dropinto the channel 13 in liquid state until the generatorbecomes hot enough to vaporize it. For

the purpose of preventing the oil from following along the underside, of the'generator and dropping into thechamber 6 the lower edge of the generator 'is' provided with a plurality of' spaced outwardly extending projections 24 which are providedwiththe designates a supply "gas grooves 25 which will lead the oil out to the points of the projections 2a where it will drop into the channel 13. After the generator becomes thoroughly heated the oil will be vaporized and will thus be discharged in a circular sheet all around the generator.

The chamber 6 has an inlet opening 26, providing for the intake of air from the free atmosphere, or for the connection of a flue leading from a conventional blon fan in case such blow fan is used.

What we claim is 1. A burner including a cup-like support having an air chamber therein, an annular base on said support, a generator above said base having an internal chamber, a generator cap spaced above the generator forming a channel between them, an outlet connecting the generator chamber with said channel and afuel line terminating in said generator and having an outlet leading therefrom into said channel.

2. A burner including an annular base, a detachable combustion ring thereon, a cupshaped support sustaining said base and having an air chamber therein provided with an air inlet, a fuel inlet line leading up through the base, a hollow generator above said base and secured to the upper end of said line and having an internal chamber into which said line discharges and provided with an outlet opening and a generator cap disposed above said generator and spaced therefrom and forming an annular channel with which said outlet opening communicates.

3. A burner including an annular base having a central opening and having a channel around said opening, an outwardly flared combustion ring on said base, a cup shaped support on which said base is mounted, said support having an air chamber provided with an air inlet, a central spider carried by the base and formed with a bearing, a generator having an internal chamber with an outlet opening leading upwardly therefrom, a fuel inlet line extending up through said support and bearing and attached to said generator and terminating in the chamber therein and a generator cap fitted over said generator and spaced therefrom.

4. A burner including a generator, a generator cap fitted over and spaced from the generator forming a channel between them, means for delivering fuel into said channel, an annular base surrounding and spaced beneath the generator and having an upstanding outwardly flared rim removable therefrom and forming an annular combustion channel around said' generator, the nipper margin of said ring extending above the lower margin of said cap.
