This` invention .relates to burners for kerosene and otherliquid hydrocarbons and is particularly intendedlfor producing a stoves,v furnaces,` ranges, etc.

Above the meinbervloff, ,l

' `bell-shaped member 19 constituting a flame-p Xthey'initial-combustion chamber shell is a guard and flame-deflec'tor. This member 19 'is supported by screws 20 of the platform 18, by means of which screwsthe height of the member 19` with reference to the member l may be adjusted as desired. The interior` .of this member 19 of course constitutes a said; fuel-heating tube, eXcept where 'the llegs of rthe fuellheatino4 tube pass transversely across the path of the flame, opposite further combustion chamber. Upon this -member'19 rests a further-flame deflector 'and draftdirector, `21,I which member '21 in practiceis of two-part construction, its two parts being secured together by' means of boltsy22, said member21 restingfupon the :flame vguard 19. f r[his flame-deflector 21 has a depending skirt 23. Thevflame, issuing from the orifice 17 offburner shell 15, is 'g directed downwardly and as a flame annulus,

byfdefiector 19, and issues through lthe an nular space between the lower edge ofthe deflector 19 and theplatform 18, spreading horizontally until lit passes the lo-Wer edge of the skirt 23,a'nd then rising moreor less directly. formed'incloses the fuel-heating tube 3 but `does not, ordinarily, directly contact with the lip at the bottom of deflector 19; and

these two points'of contact of the flame of"V lthe 'fuel-heating tubev are extremely short 'and moreover conditions are such at 4these points that `contact ofthe flamewith 'the bythe gas itself, inits passage between shell f v-fliel-heating tube is not harmful;

downwardly flowing current of air, induced d v'le-land flame-deflector 19, the deflector `19 having in it air admissionports 24 .through which. this vdownwardly flowing current ofair passes'to mingle with the outgoing flame. The flame deflector 19 has at top a boss 25, externally grooved or corrugated, as is the upper surface of said deflector v19 ;-andthe portion 26 of the deflector 21 which surrounds this boss is spaced awayl thereform and 'flaresloutwardly and upwardly, forming therefore, asto the down-A wardly flowing air current,r a contracting vpassa`, ,e leading such aircurrent to the air` admission openings .24. lVithin the deflector 419 is a secondary deflector`27, 'above` vissuing through opening 17.

"i The platform 18 is provided with Various 4Therising flame annulus thusp In the.` space within this annular `flame there is` a draft openings, 29, 30, Yand beneath said platform 18- there. is a trough 31 adapted to containV water; said trough being supported `bythe platform 18 and being also provided with draft ports 31a substantially register- `ing with the draft ports 29 ofplatform 18. The watercontained in this trough is vaporized by heal-i radiated from the flame and by heat conducted through the metal structure of 'the `burner,".the water vapori thus produced minglingwith the flame-landmaterially f modifying the. .character of 1 the 1flame,l producing a muchfhotter flame than would otherwiserbe obtained, and one which 'is much less likely1 todepositicarbon.

The action of this burner, supposing it to be already in operation, is as follows: Oil,

` forced upward from the tank 1'to pipe 2, by

the pressure of the compressed air `or other.

gas in said tank, passes into the fuel-heating tube 8, and in passing through said tubeisv subjected-to heat radiated inward from Vthe `hollow I cylindrical flame surrounding said ltube and passing up through'thespace Vbeitween flame-guards ljand 36; the iradiation of such heat. being vmodified "as to itsinliuencefon the fuel-heating .tubeyby the of tank `1 by anumber oflegs 33; The flame arranged concentricperforate "flame-guards downwardly flowing current "of relatively.

W'here-the sides ofthe fuelheating tubepass through thefiame, as they do justfabove platform 18V they aretranslcold airwhich enters thecont'racting top of verse to the path of the flame, the portion lof* the tube` so passing fthroughthe flame being therefore, lvery small. Moreover," inl one of "such portions ofthe fuel-,heatingV tube, the

oil is'stilltoo cold vto be' vapori'z'ed,A whereas in the other such portion of the tube the oil exists inthe formof `a vapor; therefore' the 'ldirectfaction of the Aflame on these small portions of thetubewill not cause formation ofv l deposits -in either lcase.

By reason ofthe substantial freedom of the fuel-heating tube from actual contact with the flame and by the reason ofthe modifying action ofthis downwardly flowing aircurrent, the fuel-l h'ea-ting tube is maintained at a relatively moderate temperature which, however, isv

sufficiently I high .to thoroughly vaporize f the oil, or to heat the oilA to a temperaturesuch that when it emerges from the burner orifice 11 it immediately turns intoyapor, but withcracking of the'oil, such as re '-sults Yin formation oflcarbon or tar deposits.y
