. therebyholding the inner member as respects the inlet end vaxially disposed within the housing 8. The inner member as respects'its tip is provided with upper-zand lower con? verging faces 12 and 13, i. e., with similarly angularlyV disposed faces. Likewise, said iiiner member is provided with two similarly laterally disposed faces 14 and 15. These faces inthe form shownin Figs. 1, 2 and Sare straight and parallel ,each other, i; e., they' are similarly. angularly disposed; The forwardI or inner orburner end of the housing member .8 1s provided with two converging faces 16 and 17 which substantially parallel and 21 operatively disposedin housing member 8 function as adiusting-means whereby the faces 12 and13 of the inner member. 9 may beheld in predetermined'spaced relation to the faces 16 and 17 of the, housing member 8.v

This provides for directing theshe'et of'flame atl the desired angle to a plane passing. through the axis of thedevice and parallel-1 ing 4thel walls 22 and23,.which form the boundary ofthe' outlet port 24 ofthe inner member 9. rlhe walls l'a'nd 26 complete the boundary walls of said port 24. o

, -Liouidfuel such as crude oil enters through the nipple 11 and intov the, conduit27 and is caused lto ilowftherethrough, either under pressure onby gravity. Through inletY 128 formed in a demountable cap 29 suitably secured vto honsing'member 8 by means of screwsl 30. fluid under pressure, such as steam or air, enters the conduit 31 formed between the inner member 9 and the outer housing member 8. The steam upon discharging through the constricted opening` 32 vand through the constricted opening 33 is directed with much force against the oil stream' issuing from port 24, breaking the same up into member 8 and the inner member 9 is inserted through the burner end of housing 8. rlhe end portions of housing 8 are demountable in this modified form and are releasably held in this position by means of screws 34 and 35.

lthe inner member which are diverging with respect to each other, i.e., said oppositely disposed faces aresimilarly angularly disposed.vv Correspondingwith vthese faces of the inner member 37, the housing member 36 has faces 40r and 41 diverginglydje., simi 'larly angularly disposed, paralleling faces 38 and 39'.l Here likewise'faces and 41 are provided with restricted faces 42 andi43,which Vare of a height substantially equal to the widthfof the outlet port 44, the remaining portions of the faces 40 and 41 functioning` to assist in holding the burner endportion ofV the innerl member 37 in position. Inner member 37 in this modified `form may be providedV with lugs 45 on the inletend of the' burner which assistsin holding the inner end of the inner member in axial position Vvwithin the housing member 36. A'liquidfuel'or oil pipe, 4notv shown, which conducts 'the Yoil to the inner member and which may bescrewed into the inner end portion ofthe inner member 37, likewise may hold thesaid end-portion Vin axial position. "A coupling on the. end of the steam or air pipe, not-shown, :drawn tight upon the bearing 46, serves to leadl the steamv to the chamber 47 surrounding the inner memberv 37. The mode of operation of 'this'modi'tied form is in all respects similar to that shown in Figs. 1, 2v and 3;

In the modified form ofV inner member shown Vin Fig'. 7, a drip groove 48'is preferably provided so that when the operation of the Vburner is interrupted, anyoil that-may tend to. flow down the face 13 is stoppedv and compelled* to drip into the combustion chamber which isordinarily in avery heated condition immediately after cessation of operationof the burner. Obviously, drip groove48 preyents the fuel from running back to .port 32 and becoming carbonized therein, so that the Aburnerautomatically maintains itself in a clean condition both'as respects the port 32 andrconduit 30. This hasv been found in operation to serve a highly-important function in maintaining' the said burnerin any operatively clean condition. I preferably provide said groove 48 in bothfaces 12 and ,1.3, so thatthe burner can be installed in an inverted position if desired. y I

' By providing a burner which has the linner member adjustableY and thereby providing for disposing tlieiiame at "any'd'esired angle,

my burner isadaptedrto be installed in any `of the standard types of combustion cha1nbers nowin use with the minimum of alteration of the mounting means. The burner thus described embodying my invention in any of its forms is characterized by simplicity of construction. Said housing and` 4inner member may be castand the only mae chining 'required is confined to providing the of burner now commonly employed, and the burner embodying my invention is characterized by maintaining the linings and flue free of soot and providing a cleaner and whiter fire than heretofore.` Repeated installations indicate that the burner embodying my invention provides a much better atomization of the fluid fuel than hasbeen heretofore obtained.

Obviously, changes may be made in the forms, dimensions and arrangement of the parts of my invention, without departing from the principle thereof, the above setting forth only preferred forms of embodiment.

I claim:

l. An oil burner embodying two independently constructed members, namely, a housing member and aninner fluid fuel conductor member, the burner end portion of which extends beyond the end of said housing member, the burner outlet of said inner member being of rectangular formr in cross section, said end portion having its opposite exterior faces angularly disposed, said housing end portion having faces parallelinff the adjacent said faces of the inner mem er; adjusting means operatively disposed in the burne er end portion of the housing whereby one pair ofthe said faces of the inner member may be held in predetermined spaced relation to the adjacent pair of the said faces of the housing member so that the direction of the flame may be controlled in two opposite directions; and means at the end opposite the burner outlet whereby said inner member may be held in spaced relation to the housing member. y

2. An oil burner embodying two independently constructed members, namely, a housing member and an inner fluid fuel conducof oppositely disposed faces of the housing member holding the inner member in pos1- tion; adjusting means operatively disposed in the burner end portion of the housing whereby one pair of the said faces of the inner member may be held in predetermined spaced relation to the adjacent pair of the said faces of the housing member so that the direction of the flame may be controlled in Ytwo opposite directions; and means at the end opposite the burner outlet whereby said inner member may be held in spaced relation to the housing member.`

In witness whereof, I hereunto subscribe my name this 9th day of August, 1928.

GEORGE L. BARNES.
