The conveyer comprises an endless chain ,10 carried .upon rollers o r sprocket wheels 11 mounted upon shafts 12 which shafts are journaled in the sides of a fuel receptacle 13 surrounding the conveyer. For driving the conveyer Iemploy a friction disk 14 mounted upon the outwardly projecting end -of .the gu per. shaft ing mem j 12. A `frictional drivr 15. is `arranged adjacent to the 1 disk 14 and ijn engagement therewith, and

is slidably and non-rotatably mounted upon a vertical .shaft 16. Onjthe lower `end of said Ashaft =16 1s a worm gear 17 in mesh withan endless screwyl8 upon the armature shaft of a motor 19 which is the 4source of' For varying the I provide a bracket 20 embracing upper and lower surfaces of the frictional driving member, said bracket being slidably mounted in a supporting casing 21A and held in speed at which the fric-- tional disk 14 and upper shaft 12 are driven,

For supplying fuel to the receptacle 13,1

have-provided a float valve Achamber 2,4,within which is carried a float'25` controlling 'an -li'nlet `valve 25 vfor establishing communicaf vided for bythe employment of a pipe 24a.y

this arrangement I, am able to maintain "a substantially constant level of the fuel withiny the receptacle 13. A

Obviously, with the lower portidn of the fu el conveyer submerged in a body of tar or other viscous fuel within the j receptacle 13, the

conveyer, Awhen operated, will carry with it particles of fuelk to the top thereof and at this point I haveI provided the foll vvy for atomizingwthe fuel ard'nr` ing means jecting it into a chamber, or other desired place, for combustion: A' blast pipe'27, hava discharge end constricted and xed that the blast of air from the pipe 27 will f Vformed. A burnertip. and conduit; The other end of `the burner'tip communicates with a furnace adjacent tothe upper end of the fuel con Veyer,.is` connected with a. source of com- .pressed air supply and arranged inv such-4 a manner that air is' directed tangentially -along the upper arc .of the conveyer with such vforce ,t at fuel contained thereon will be' 'carrigdawayfwithand atomized by the blas't of air '-A as one. of its ends. surroundbeveled, and surrounding the Vbeveled end thereofi's a. burner tip 29,.also beveled, and

so arraii edi"that an annular opening 29 is et-ween the adjacent ends 'off-the or other `heatin chamber 30..

From what as been-said,`it is obvious be directed through the conduit 28 and burner tip 29 into the furnace or' chamber, and in .'passingover the upper end of the fuel conveyer, 1t will carry with it and become thoroughly commingled with the fuel thatis Vcontained thereon,`v and thusjproduce a coinbustible mixture.l

' for y duit 28.

For more thoroughlyatomiaing the fuel and Anannular air chamber 31 the burner tip 29and a :portion of the con tion with a ipel 32 connected with a source of air supp y of considerably -less pressure than that supplied to-{the lblast pipe 27. A casing 33 formedl on the fuel receptacle 13,

, preferably integrally therewith, projects f as -ings 34 is pifjovi'ded in the sides v29{i formed within the' air. chamber 31 and surrounds the adjacent coperating` ends of theconduit 28 I j and burner tip 29, forming at the same time Vadjacent ends of the burner tip and conduit, it will be seen that air passing through the opening 29a enters the burner tip in forwardly converging lines and in this way it becomes thoroughly commingled with the fuel from the conveyer and a more thorough the adjacent end of the air chamber,

atomization of said fuel results. The outer end of the casing 33 is beveled, as is also and by spacing the end of the casing distance from' the beveled end of theair chamber, an annular opening 36 is formed conduit 28 fixed in a remov-j -ab1ecapf28m screwed into thel receptacle 13,

iso-arranged adljlacent tothe upper end of the conveyer andl ing the discharge end of the blast pipe.v The oppositeend'of said conduit is preferably spreading it to increase the area. of the llame, I have provided the following means:

is varranged prefcrably, upon the furnace 30 and surrounds4 35` This chamber is in communica--` apart a slight which admits .air"froi'n the air.. chamber' facross the discharge end of the burner tip and into the furnace in `cross directions. In this way the combustible: fuel from the burner tip'is spread evenly in all directions, andthereby a considerably increased area of the flame will result.

The lower portion of the casing A33, it will be seen, -is not proyided with the perforated open'ings 34 1as are the upper and 1 side portions,so that any -ffuel which may collect upon the sides of the burner tip will pass'downwardly through the annular open- 1ng.29a andinto the casing, from where it will be delivered back into the fuel recep tacle through a by-pass 37 formed in the receptacle for that purpose. u

For regulating the quantity of fueldelivl ered 4by the conveyer for a given speed, I

4ha ve "provided the following: A screwthreaded sha'ft 38'passing through the side ofthe receptacle has fitted to its yinner enda roller 39, and on its outer endl is provided with an adjustin nut 40..' This shaft is nonrotatably journa ed in a bearing 41 formed on the receptatcle and by turnmg the nut, the shaft is moved in either direction tothe desired position. .'lhus`,' during periods o f low tempertaure, the roller 41 can bemoved close to the conveyer and heavy lumps of tar will thereby be remoired Also, by hav. ing the position ofthe roller adjustable, the size of the flame can be controlled through the regulation of the'fuel. 1"'

While I have shown and described but one form of my device, it will be understood, nevertheless',A that it is capable Aof many modifications and vthat changes may-be resortedto in thea'rrang'ement and construcf tion' thereof WithoutI departing from vthe spirit-of my invention appended claims.
