and outlet I.ends :being :located knear each other and at one side of '.the space surrounded .by .the retort. 18 represents ,an elbowshaped vapor conduit, the .upright portion of whichcommunicates withthe outlet '17.' The horizontal portion .of v.thel vapor conduit extends over a '..portion of .the zb'ase, and is supported vabove the .bottom ofthe base Aby a seat 19 .formed on .the :base yIn the said horizontal .portion :is formed a .vapor outlet 20 ywhereat the vapor ris ignited, the said outlet 20 being arranged .to proiect a flame upwardly into the center of .the space surrounded bytheretort `14. i i

21 represents a circular :flame dellector supported in the space surrounded by the retort, the circular margin of the deflector being substantially parallel with thefretort.' The deflector .is adapted -to project .theflame radially against substantially all .partsofthe inner surface of the retort, `the -deflector being preferably constructed as shown by Figs. 2 and 3, and including-a disk'fsl'laped top portion whi h changes the course of the upwardly directedflam'e, an annular #flange 22 depending from the top and provided with numerous perforations or small orifices 23, `adapted to subdivide the -ame 'finto a multiplicity of small jets, and to project said jets radially'agaiinst vthe V,inner surface ofthe retort, and fa bottom plate -24on'the lower edge of the flange 22, havinga central opening which conducts the :flame into the chamber formed 'by/,the said top, flange, and bottom plate. i

The deflector is preferably provided with a flame conduit 26,which enters theopening inthe bottom plate and vdepends `from said plate, the vintake end off the )llame conduit being located over Athe1vaporoutlet`20. y

The'base 12 is provided at opposite'sides of the seat 19 with aircondu'itsf28 extending through and above the base, and arranged to conduct air into the intake endof-th-e ameconduit 26, said intake endbeingpreferably lenlarged or bellshap'ed, as shown by Figs2and`3.

The viame deflector is preferably `su ported removably by means `of an elbowshaped arm 30, attached atone end-tothe base, its horizontal end portion overhanging a portion of the retort, and an' ear31 ,formed on ,thefdeflector and having an opening 32, which permits the ear tobe placed on the arm30, as indicatedlby Figs. r1,2- andf3. The' the space surrounded by theretort, .and .in

on a single .base formed as indicated byY .the vapor conduit: 18 by ear opening 32 is of sui'licient size tofpermit the ear to be slipped on to and off from the arm 30, the upper side of said arm being preferably provided with a notch at 33 "(Fig.' 2) formed to engage the upperfsideof the opening 32 and prevent accidental''n'i'o've'inentVr of the-v ear. on the arm. Provision is,there fore made for heat from the ear 31 and the Haine deiiector.

The retort is supported in part by the` oil conduit 13, which islocated at one side Vof part by a strut 36 interposed between the retort and thebase, and located at the opposite side of saidbase, provision being thus.

made V.for preventing-thedisplacenient of the retortby warping.` j

The-retort as shown in Figs. 1 and 2, is formed as a'gco'ntinu-ous; annulushzwing an enlargement 37 in which the intake end 16 and outlet end 17 are formed, the retort thus constructed beingpndapted to be formed as a casting. The retortmaybe formediby bending a length Yof .Wrought metaltubing, the intake endlba being at one end of the tube, "andthe outlet end 17L being at the opposite end.: The intake end may be Vconnected With the oil-conduit 13 3.8,v and the outlet end may be connected With an'elboiv V39, as indicated by Figs. 4l, 5, and The described structure may be duplicated Figs.1'andj2, to support tivo' vaporizing burners of the, above-described construction ln starting the operation of the burner, aV

limited charge Vof oily is suppliedV to the panshaped base, and ignited, a charge of oil beingkat the same timeadmitted to the retort, the supply to the ietort being then shut off. vVlhen `the Voilburning on the base has sulicientlyheated the? retort to vaporize the oilY therein, the vapor is ignited at the outlet 20, Vvandthe resulting flame is projected as above ,described against the retort. Vhenr the operation is sutliciently started,'the sup.l ply connection tothe retort is opened and` the burner thereafter operatescontinuously.

The retort may be made oftivo horizontal sections 14a and'lf", as shownv by Figs. 7 andV 8',`garranged in parallellplanes, the sections labeing provided with the'intake 1Gb, hav-3 ing an'. enlargement 16C, While the'section 14h is provided, With the outlet 17h, having an enlargement 17 C, said intake' and outlet be-y ing:connected, respectively, Withthe oil con- "conveniently displacing the" v deflector and permitting accessto the vapor r conduit 18- and the vapor outlet 20 therein.

by an elbowV (Fig. 2), or 36a (Fig. 8),

.'nected'at 41 by a ysuitablel connecting meinber, `or vapor conduit, as shovvn'by Fig; 8.

"I he 'deflecto'r'is arranged to discharge jets of flame simultaneously on and between the tWo sections. vThe flange 22 .ofthe deliector. is arranged in a horizontal plane .Which is parallel with is, therefore, more efficiently and uniformly:

heated than it WouldV be if composed of av single'helically .coiled tube, the convolutions of which are in contactwith each-other, 'and' are inclinedl relatively to the plane ofthe iange ofthe flame deflector.

The sections may be of substantially rec-` tangular form, lasshoivn by Fig. 7, and the deflector may be eithercircular, as shown by the planes ofthefsections leaand leb: In.

Fig. 1, or of rectangularform, with sidesV substantially parallel With the inner sides of the retorts. Y *Y f The sectionsinaybe supported lby a strut or bracket 36a (FiomV 9)., suitably secured to the base and provi ed With ears 361),.one projecting over the upper section, another pro-V V jecting between the two sections, and "the third projecting below` thelower section.'

The term retort as used in the first two ofthe following claimsV is intended to mean either a single retort having itsV intake and outlet ends at the same height, as shown by Figs. 1, 2 and 3,or a retort composed of secby a 'vapor-conducting confY tions connected nection 11, and having intake and outlet ends' located fat different heights, as shoivn by Figs. 7 and 8.A Each form of retort may beeither'ofsubstantially circular or annular form, as shoW-n .byfFig.,1, or Aof substan-V tially rectangular form,ras shoWn'byFig. 7.

It Will be seen that in each embodiment of the invention, .the intake internally threaded portions of the'elbovvs 38 and 39, (Figs. 5 and), and-the inter-V nally threaded portions of the enlargements 16 and 17 C' (Fig. 8).r One of` said coupling h and discharge' ends of the conduit are provided With coupling internally threaded' members detachablyengages a complemental coupling' member formed by an external.

screivy thread on the oilcondui-t 13and the other detachably engages aV 'complemental coupling'. member formed vby an v:eX-tfirnal lscrew thread on the vapor conduit, 178. In;

each' einbOdimentthe supporting strut '36 v is detachablycone ne'ctedvvith. the retort; yProvision is there` fore madefor locating the retort and maintaining it in its predetermined location by the oil conduit and the strut, and for confining the vapor conduit in its operative position by the retort and by the seat 19 on the base. l
