To all whom it may concern:

Be it known that 1, JOHN W; Fnnunn, a citizen of the United States, residing at Phoenix, in the county of 'Maricopaand,

Specification of Letters Patent I t nt d Application'filed March 20, 1920. Serial No. 367,555. v

State of Arizona, have invented certain new s and-'nseful Improvements in Burners, of which the following is a specification, refer ence being hadv to" the accompanying draw-- ings.

' This invention relates to an' improved burner and preferably to the'type with which coal oil as a fuel is usedi' I 7 P Many burners of this kind have been i found more ofr less 7 of very little real value owing to their expensive complicated construction, therefore, the invention aims to provide an improved coal" oil burner WlliCh is verysimple, efficient and practical'in construction and capable of being cheaply made and sold at a reasonable profit. 1

' As a further object it is the aim "to provide a coal oil burnerwhich'isnot expensive to install and operate, and furthermore, will operate with a minimumamoiint'of fuel; In, other Words, a very'small amountof fuel is allowed to; enter the gas" chamber together with air 'tomix with the oil "Vapor and at the same time'will' generatelaf great amount of heat.

The invention still further aims to pro vide a burner of this kind wherein angelon- Additionally the invention embodies islot' Feb. 22,.

oil is vaporized and-is mixed With theair; Y the charge is capable of being-ignited as it leaves the burners by placing the lighted asbestos over the slots. "Astheburner's'are' either to the side orunder the generator, the

heat from the-burners ascendsandkeeps-the' generator highly heated so as to' always I vaporize the foilas'it enters the generator.

ted burners vv'hich consist of burner chamber provided with laterally extending" tubes 2 whioh are slotted to permitiof thees'o'ape of V gated tubular generatoris employed, ;sup-

porting the burners asshowm there'being a gas chamber in communicative connection with the gfi nerat or, in combination with an air supplypip'e communicating with the gas chamber at a point Where the chamber and the generator connect so that a niixture'of air and gas is allowed to enter-thegaschamber and'thence into thebiirnerfivvhere the mixture may be ignited; v

saturated asbestos member held'in a "position beneath the generator inorder to initially heat the generator for the purpose of vapor? izing the coal oil or other fuel, which issupplied to, the generator and as the mixture of asbestos member mounted-on a handle is first saturated with alcohol or gasolene and 1s 0 then lighted and held under the generator untilthe oil is properly vaporized. the

The invention also embodies the use of a;

the'bu'rning gas in order that it may be ignited as it passes off-from the burner; It is also the aim'to' provide ashutoil cockin the gas chamber so as to s i when onlyone-is I'I'eeded' While the 'designgand construction at res: ent illustrated and set &forth is deemed pref-f erab1e',jit"'is obvious that as fa result era reduction of the invention to a more praca" tica'l'fo'rm" for' commercial purposes-the in vention may b susceptible to {changes, and" the right to [these changes is claimedi piro' vided' they are comp'rehended Within "the scope of What'isclaimed? 5" The invention comprises vfurther T features and combination of parts, aSfWill b'e-herein! after set forth, shovvn Lin the draivingsf In the drawings 1 Figure'l is a perspective view of the ii n proved 7 burner constructed "in"accordance} With the invention; and showing the/same? mounted upon supportinglegs, in combina tion with a skeleton p1ate;or frameover the burners for the [support of cooking vessel's," and'thejlike, r a F 'g; 2; is aflongitudinal sectional; view' o'n :Fig. -3 is a sectional plan o ag- 5 1. v Fig. 4 is a'transverse sectional vieudoni Line 4 4-OFig.- 3,

2 W Q y & u ly ipe' 3 of a'fuell tank I hut offone' burner i viewf o'n line 3 -53 J may be connected in order to supply suitable fuel, preferably coal oil to the tube V V, or pipe 1. The interior'of this'tubeorpipe 1 is provided with a plurality'of wire fabric; disks'2 arranged at intervals, and interme-: diate asbestos fillers 3 through which the', oil percolates and as the oil percolates' through this filler of asbestos; the-;carbn' is eliminated; I: This tube or pipe 1 with its interior filler constitutes a generator-whlchbecomeshighlyheated so that the oil, when .7 it percolates through the. generator, becomes vaporized in .order to thoroughly mixwith the air in the. mixing gas chamber. The end of the tubeor'pipe 1 opposite its coupling 2 is'provided' with'a cap -3 having a very smallorifice orneedle opening 4topermit gas and vap.or.;

of. the escape of thevapor which is'genei ated from the oil in the generator. This vapor 'asitisgenerated enters the gas mixing chamber where it mixes with the air which is drawn thereinto. The end portion of the tubular generatorhaving the cap 3 passes through cap 5, which'is'connected' to the end portion of the semi-circular part 6 of the burner. This semi-circular part 6 has an air and gas mixing chamber 6 and connected to this semi-circular .vpart 6' s5 a valve 6'? which may. be open to permit air to enter the mixin chamber to mix-with the I his semi-circular part, is coupled by means of the unionG to the pipe or tube 7, which hasa gas chamber-7; intov which the mixture-of .gas and air enters. The gas chamber T is elongated and may be anysuitable length. -Atubula-r brace 11 is -provided and has'one end coupled 'by means ofa" union 11 .to a curved semi-circular part 6 of the device. The otherend;

of the'tubular brace. is. coupled by means p of the unionll to a' semi-circular tubular by means of union 11% to the gas chamber" tube or pipe 7. The union 11 is in the form" sectionor'brace 11 which in turn is coupledof-a sleeve or coupling With a centrallylocated division wall, acting to vclose the end of the gas chamber pipe or tube In fact,- there .is', no communicativeconnection be- 7 connection 10 of the curved tubular-brace;

-, Projecting laterally outwardly and downwardly fromv thetube or pipe T are suitable supporting legs 21. Also projecting laterally and downwardly from the brace tubfef11 are supporting legs 22,'which cooperate with the legs 21 in order to support theentire burner structure on a table or other suitable support.

A skeleton framevor what maybe termed a .hot plate 23 is provided; This skeleton frame comprises the outer marginal portion 24 and the circular vessel supporting'innerparts 25, which have inwardly extending .web portions 26;}The vinner circular parts 25 of the skeleton frame are connected to the outer .marginal portion of the frame by means of thewebmembers 27; This skele manner oventhe burner apparatus, as for instance by means of the supports 28, which may be either integral or-detachably connected to the brace tube 11 andthe tube 7.

As this is a minor. detail as to how the supports 28 are connected, it is immaterialwhether they are shown asbeingintegral or detachably connectedto the tube orpipe *7 on. the brace tube or pipe 11. Itis to be. noted that while this vesselsupporting skel' eton frame or hot plate is 'shown and de scribed, it is ,to be understoodthat it does not constitute anessential part of the present invention, 'Withthe exception that it provides a means for; supporting the vessel over the burner proper, and if necessary the plate orframe may be so claimed, that is to say generically in order that'any form of frame can be used It is also immaterial whether theburners proper extendglaterally from the generator pipeor tube or under the same, as' this s a an mmaterial unessential 'detailu However, better results have been obtained by dlsposlng the burner proper under the generator tube or p ipe;1 in order that-the heat from-the burner proper may impart heat to the generator for the purpose of pie-1 heating the, oi-l and thereby vaporizing the same i As shown in Figs; and 6,'thebiu'ner apparatus is illustrated. as being extended by utilizingan. extension .lnu'ner. I In order to: ageomplislnthis it is-to r benoted that the,

ton frame may be supported in 'any'suitable,

unions 11 and 11 are detached andin their stead aburner extension 28 issubstitutedl .This burner extension 28?.is connected to'the tube-orpip'e 7 by the union-29. This burner extension also includes an extension 'generator tube 31 which also assists in supporting additional burners 32 proper. This extension genera-tor tube is coupled to the generator tubel bythe union 33. The extension 1 burner includes an extension brace tube"3&

which in turn is :coupled by means of the union '35 to the brace tube 11. The extension ibraceztube and the extension tube (which is connected tot-he tube or pipe 7 have additional legs 36 to further support the; app-a1 ratus. After applying the extension burner of the vunions 11 and-1'1 frame 37 in a similar manner-as the first skeleton frame. This extension frame'has the ends of its side pieces coupled as at 38 to the, firstskeleto'n frame so that the entire structure has rigidity. It will be noted that by the construction herein disclosed, a

1 burner "construction of considerable length may be devised, so that quite a number of cooking vessels may be supported over the burner proper, so that quite a number of articles may be cooked upon the device at one time.

As shown in Fig. 7 a. handle member 39 is provided having an asbestos body 40 on one end which may be saturated with alcohol or gasolene and held under the generator tube thereby acting to impart heat to the generator tube 1 so as to vaporize the oil as it percolates through the web and asbestos filler and then when the proper mixture of gas escapes from the slots of the burners proper, the lighted asbestos body of the handle .may be held over the burner proper in order to ignite the gas. The flame from the saturated asbestos body will rise and highly heat the generator, thereby vaporizing the oil and this vapor will pass out through the orifice or needle opening and subsequently mix. with the air passing upwardly into the mixing chamber of the semicircular part 6 of thedevice. The mixture will then pass on to the burner proper. The pipe including the air controlling valve to the mixing chamber acts as a flue which furnishes air to be mixed with the vapor passing from the generator into said mixing chamber. This improved burner is designed for use in country towns or cities beyond the gas district and also may be used in other places where no heavy fires, are required. It is obvious that a meal can be readily cooked on the surface of the skeleton plate as well as upon the upper face of any conventional form ofcoo'k stove and as well: as'onlany other gas StOVGlGCGlVlIlg its supply from a plant. The present device'may' be used as a 'hotplate for general cooking,

the same as used with natural gas and the same has been found very -.much' needed.- Whenthe mixtureof vapor'and air escapes from the slots of'the burner proper-'and fis. ignitecha very hot blueflamei isprovidedu;

-The semi-circular. part 6 of the burner-is provided'with a valve controlled'outlet 6 to.
