Referring to Figs. I and Il, 1 designates a suitable base adapted to rest on the grate of a stove or other-suitable support. An oil cup or openftopped oil reeeptaole 2 is formed on the top oiA a tubular support 3 Whicfli eX- tends upwardly 'from base 1 and has an interor passage extending through. the oil receptacle, said oil receptacle being formed an annular @up sur?.y :undinff said passa e. Lateral perforatons .5 extent through t ris tubular support. Surrounding the tubular support 3 is a rim or Wall E which is desirably loose or removable, resting on the base 1 and laeld .in place by pins or lugs 'Z on said Abase. The space between said rini 6 and tubular support 3 'forms an exterior passa e 8 which extends ulnvardbT around the tuular support :uid around the oil cup, and air passages or lroles 9 are provided in the buse `1 eorn redini-.fusing with said outer passage S.

delleeing cap 1i.) resting on upward im ns or lugs 11 on top ol tile tubular su A extends overtne inner passage fr and completely over the oil oup to the outer edge thereof forming a. contrat-,ted annular opening orpassage between the doWnt-urned external lip of' the eap and the upturned edge; riin or lip 13 of the oil cup, so as to deflect the air from the inner passage over the oil in tluheu'p and out througlr'said am 'nular opening. The air passes from the inner passage 4 to the Vaporizing Chamber or space over the oil cup, through the openings Y The cap 1() is provided with lugs 14 on s under side which engage outside of lugs .l to hold the cap .in central position, these lugs 14 being lugs 11 in all 'rotative vpositions of the cap 'while allowing free draft 'passage between- 5 and removed.

f "l the burner above described opera-tes satisfactorily, burning with a clear flame when the stove is closed, it is liable to smoke somewhat when a stove lid is removed, owing to diminution of suction and consequent 'decrease in flow of air between the oil cup and the cap. rFhis may be remedied by the provision of an auxiliary draft iue 28 shown in Fig. VI extending from beneath the burn/er base 1 to some distance below the stove, for example, through the floor 29 into the` cellar or room beiow. This auxiliary draft flue being attached to a plate 30 on which the burner; base rests, becomes heated `by con# duction and an' upward draft is produced therein which will maintain a flow of air vthrough the burner sufficient to y roduce thev carbureting eect evenfwhen t estuve is opened.

inastove or fire-pot, indicated 9.13.23 in- Fig. I, its base 1 acting as acl'osure for said fire-- stove to pass through the burner passages; Oil'bein turnedon till thecup 2 is full and preferab' y overflows, itis lighted at any convenient point, for example, atthe wick 18 if the latter be used. The lame 4heats the .tubular support 3,' leap 10 ahd in- A closing ring Gand the regular eom'bustionof thevburner will then proceed.. The eater part of the inming air will pass-up trough the inner `air passage 4 and will be deflected B5' bythe cap 10H50 as to pass over the oil in the In use, the burner will generally be placed' pot'so as to force all the natural draft 'of the quickly i cup 2 and out through the annular opening 'between theexternal lips of the .cap 10 and the oil cup, and the oil vapor which arises froml theoil in the cup is instantly mixed with and carried out by this current of air. The mixture that thus passes out from beneath the deecting cap, meets the current of air passing upwardly in the outer passage y 8 and-is deiiected upwardly, burning w ith a cup-shaped, clear, hot flame.

J will be understood that the air which passes up both the inner ,and outer passages aforesaid will be heated by the adjacent metal surfaces whereby such air is rendered .more eflicient both in taking up the vapor `and in the combustion thereof. The outer, \inclosing ring 6, serves to absorb part of the heat from the flame and to carry down and transmit such heat, by radiation and condution to the other parts. Any. surplus or excess of oil supply thatmay run .over the rim ofthe oillcup 2`Will .be partly vaporized inpassing down over the flaring lip surface lendif any remains, it will fall on the disv tributer plat-e or ring 17 and 'will thereby be spread out and vaporized. The object of the flaring surfaces at '1-3, 1.6, is to prevent the oil from falling to the base in large drops and to force the oil to spread out and expose a large surface to the heated air and metal.

If the excess of oil'is beyond the vaporizing capacity at both the surfaces at 13, 16, the

unvaporized portion ,Will fall into the catchbasin or cup 17 Where the vaporization will be completed It may be stated that as regards the oil thus vaporized at 13, 16 and 17, the air passing up through the outer passage 8 serves a slmilar function in mixing or carbure-ting to thatdcscribedin connection with the air passing up through the inner passage 4.

Owing tc the vdifferences or variations in the natural draft of different stoves and their .chimneys it fis desirable' to rovide means "for adjusting the liow ofair om the inner passage over the oil'to compensate for such difference in draft'.4 To this end I make the [proportions of the'parts such that the most efficient actioniis secured 'Withra Weak draft and in case the "naturaldraft of the stove to Which-.the burner is to' be applied i's stronger than such-weak draft .I apply 'Washer 21 above referred to, w ose thickness should be sufficient todiminish. thel draft' (proportionately to suchv lncrease of;

vopening draft-an maintain. the proper condition of suction through the vaporizing chamber or space over the oil draft.

' Such chan fe of draft may also be effected by use of different caps with' differently shaped external lips so as to .vary the draft opening. l

The oil deflectin and distributing flange 16,-while' a desirab e feature, is not always essential and may in some cases be omitted,

iw'tivill run directly into the drip-cup 'l' 'longitudinally through the Wall of It will be seen that by either iforin of the invention a eornpaet burner is provided having an elongated upright body portion 3 lorniingn tube open at each end thereof and having perforations 5 at dierent 'ioints along the length of the body throng thel wall thereof, and a passage 27 extending the body,y This body may be formed as a sing'leeasting, the annular extensions l5 and r16 being l'ornied integral' With the eastin and being adapted to interrupt the ilow o the oil as it passesjrom the feeding means 25 upwardly y through the passagell and overiiows trom the annular upper oil cup across the lip i3 and down the sides of the body 3, being reeeived by the cup formed by the extension 'i7 extending around and integral with the base of the body.
