The extremity of the longer arm' of the intake pipe 21 is supported by means of a screw,l bolt, or other fastening elements ,24

threaded throughv an opening in the bottom 15. rlhe extremity of thelonger `arm This pipe '21 of the intake pipe 21 terminates adjacent land in spaced relation to the end wall 6 having the openings 14 and said longer arm is co-axially arranged in respect to the needle valve structure 12. The top plate of the mixing chamber M is denoted gener-H .ally by the numeral 26 and along the median longitudinal dimension is formed withv a depression 27 forming al well under the retort generator R while the remaining rpor-y tions of the top plate 26 are perforated as is indicated at 28. The top plate 26 is held securely in place by means of screws, bolts, or other fastening elements 29 engaged in the bottom 1,5 as is more clearly illustrated in Figure 3. A baflie structure is mounted on the top plate and comprises a vertically rising continuous wall 3() having an inwardly directed flange 31 between its upper and lower edges, adjacent the former to rest on the top plate as is clearly indicated inV v the retort generator R as is clearly illustrated inFigure 3, one on each side of the lugs 32. Batlle walls 35 depend downwardly from the sides of the recess portion of the top plate 26 into the mixing chamber as is shown clearly in Figures 2 and 3. An oil pipeV 36` is` connected with one end of the retort chamber at the bottom thereof as is indicated at 37 and extends down through the mixingy chamber into the burner base and` extends longitudinally through the burner base andthrough the end wall adjacent the needle valve structure 12. A pipe 38 leads from the other end of the retort generator adjacent the top thereofv downwardlyto the needle-valve structure 12.

Attention is now directed to, the circular embodiment of the invention disclosed in Figures 5 to 8 inclusive. In these figures the letter- I denotes vthe retort generator,`

.. the letter M the mixing chamber and the letter B. thee burner base, corresponding respectivelyy to the retort` generator R,.the mixing chamber M andthe burner base B heretofore'described in detail. The burner base B comprises a circular bottom 4() having a circular wall 41 rising therefrom adjacent.

its periphery. The mixing` chamber `M comprises a bottom 42 of circular formation having afcircular wall 43 rising from the edge thereof. The center of the bottom 42 has van opening. 44- from which depends an n elbowtubular member 45 in the lower extremity of which is threaded a pipe 46 extending through an opening 47 in the hside wall 41 and terminating in a closed flared head 48 having an annular series of openings 49 and an annularl series of openingsv 50 and a central opening 51 for receiving a needle valve structure 52adjustable by a handle 53. The bottom 42 is formed with an annular depending flange 54 inwardly spaced from its edge and extending inside ofthe upper edge of the wall 41 and secured thereto by means of fastening elements 55 or in any other suitable manner. The top of themixing chamber M is in the form of a circular annular plate 56 having a circular depression 57 in the center thereof forming a well or recess from whichl depends an annular baille flange 58A into the mixing chamber M. The retort R is of cylindrical formation and its axis is disposed vertically. The lower end of the retort generator R is reduced and externally' threaded as is indicated by the numeral 59. This reduced end is threadedlyengaged in the top plate 56 by means of the inner wall 57 on the well 57. The remaining portion of the top plate 5G is erforated as is indicated at 60. This top p ate is held in place by means of bolts 61 engaged inthe bottom 42 outside of the, wall 41. An annular baille wall 62 is formed intermediate its top and bottom edges with an annular inwardly directed flange 63 rest-V ing on the top plate 6() while the lower portion of the baiiie plate telescopes over the circular wall 43. An oil supply` pipe 64 is p.

engaged with the bottomof the retort gen.- erator R and extends Adown through the elbow tubular structure 45 and radially through the base B. A pipe` 651i`sesvert1 cally through the bottom of the retort generator R terminating adjacent the upper end' thereof and also adistance below the bottom thereofl and is coupled with a pipe 66.', extending radially throu h the mixing chamber andthrough the wa1`43 and then bent downwardly terminatingin engagement with the needlevalvel structure52.

The retort generators R and R are provided respectively With clean. out plugs 65.` and G6, the former in the end' and the-letter in the top of the `respective retort. generator. It is thought that the construction of' the. two embodiments will now be clearly understood without a more, detailedy description thereof. It will be seen that the parts are capable of easy assembly and disassembly and present a compact and convenient arrangement. rIlhese two embodiments have been disclosed in detail merely by way of examples since in actual practice they attain the features of advantagev enumerated as desirable in the statement of the invention and the above description as well as the advantages which willbe apparent from the description of the operation which is as follows The retort `generator R, R, must first be e heated and this is accomplished by inserting alcohol into the well formed by

recess

27, 57 which is provided for this purpose. This alcohol is lighted and the burning thereof Will cause theV oil Vin the retort generator to be sufliciently heated for startingthe generation of the gas through the` pipe 38,

The mixture which` will rise fire is required.

. small lire can be used or it can be increased to resemble a large blowtorch, the fire leaving the burner very forcibly. The fuel is fed to the burner from a tank (not shown) where a pressure of air is carried, this pressure of air forces the fuel to and through the burner through

pipe

36, 64. The object in making the burner in a long and a round design is so that it can be used in round andlong fireboxes or where a round or a long:7 Both burners use a large round retort generator. On the round burner, it will be noted, the generator is disposed in an upright or vertical position, whileon the long burner the generator rests in a horizontal position. A strong draft or light wind will not interfere with the operation Vof these burners while being used in the open. The burners produce a very intense heat and a clean blue blaze and create very little noise while in operation. The baffle or shields shown at 30 and 62 in the respective embodiments of the invention shown prevent a side draft which would tend to blow out the flame at the periphery of the

plates

26 and 56 respectively.

lt is apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
