Patented Apr. 22,l 1930 UNITED STATES BATFE'NTOFFICE WILBERT L. RICHARDSON, orl LOUISVILLE, KENTUGKASSIGNOR To REYNOLDS PORI-4 'ABLE FURNAOE Oo., OF LOUISVILLE, KENTUCKY, A CORPORATION oF KENTUCKYl HYDROCARBON TORCH Application inea March 13, i929. serial No. 346,613.

The invention provides a burner for general use as a torch and utilizing kerosene, 'or other hydrocarbon, as fuel.

The invention supplies a burner which may be readily cleaned,.so as to maintain its efficiency, and which may be applied to Oil burning furnaces, or used as a torch for asphalt heaters, and for thawing out gravel and sand beds, pipes on locomotives and-for any desired purpose for which a torch is adapted.

While the drawing illustrates a preferred embodiment of the invention, it is to be unn derstood that in adapting-the means to meet specific needs `and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, vwithout departing from the spirit' thereof.

For a full understanding of the invention and the merits'thereof, reference is to be had to the following description and the drawing hereto attached, in which Y Figure 1 is a perspective view offa hy-drocarbon burner vembodying the invention, the intermediate portion of the handle being broken away, f

Figure 2k is a developed View of the burner,

. Figure 3 is anenlarged transverse sectional view of the burner,

Figure A is a fragmentary longitudinal Sectional view ofthe burner.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.

The burner includes a shell or casing 1 for confining the heat and flame.. VThe Shell l tapers slightly throughout its length and is closed at its rear end by means of' a plate 2. A tube 3 is applied .to the plate 2 at a central point and projects beyond opposite sides ofl the plate and terminates'at opposite ends in points, as indicated ate. A plurality ofopen ings are formed in the` plate 2 andv are grouped about the tube 8 and'provide yfor admission of air to mixwith the gas issuing yin a jet from the burner tip or nozzle 6. portion 7 is cut from aside of the casingvor shell 1 and a pan 8 is located opposite the Opening ythus formed and vis secured to the i shell.

AA 'preheating coil or generator is located j f within the shell or casing 1 and comprises a plurality of loops 9, the samebeing disposed in circular form adjacent the shell or casing 1, as indicated most vclearly in Figure 3-lof` Y the drawings. yThe loops 9 are pointed at their outer or forward ends, and are connected in series at their inner or rear ends by means of unions 10 which consist of hollowcastings veloped view in Figure 2 of the drawings. Av leg of an ond loop is extended and connected to a supply pipe 11.. A leg of the op` positeend loop is extended, as indicated at 12, and connected to a burner tube 13 which is provided in Va side with a threaded opening to receive the nozzle or tip 6.

VA plug 14 closes the end of the burner tube 13 adjacent thenozzle or tip and admits of the burner being readily cleaned. The end plate 2 is'c'onnected to the unions or fittings 1()by means of screws 15. The shell or cas# ing 1 is yclamped to the coil orgenerator by means of plates 16 and screws 17, vthelatter passing through openings formed in the shell 1 and engaging threaded openings formed in the plates 16. Openings 18 are formed in the outer or rear walls of the unions 10, in line with they legs .of the loops9 coupled thereto, and provide for cleaning the loops of any carbon that rmay collect therein. Plugs 19 normally closel ,thel openings 18 and may also serve as supplementahmeans forconnecting the end plate 2 to the preheating coil or generator. A section of pipe 20 projects from /to each of which a legof adjacent loops iS connected, as shown mosticlearly in the deone ofthe unions or fittings 1.0.and is disposed o f yn ' n utilized 1n a manner stated.

through the loops 9 and unions or fittings 10 in a tortuous path and is heated and converted intovapor which escapes through the nozV erator. Y The iiame is conned by the shell or easing l and shoots beyond'thev end of said shell or Vcasing to be utilized in any determinate way. The burner is primed by supf plyingfa small quantity of liquid fuel'toY the pan V8 and igniting the same and when the necting the coil to the plate closing the rear of the casing.

In testimony whereof I afIiX my signature.

WlLERT L. RICHARDSON.

2. A hydrocarbonburner comprising a casing, a generat-ingcoil therein including loops and hollow castings connecting the loops in series and Yformed with threaded openings in line with the elements of the respective loops, a plate closing the. rear end of the casing, and plugs closing the openings ofthe hollow castings and forming connecting means between said castings and the rear lclosing plate of the casing.

3. `A hydrocarbon burner comprising a casing tapered in its length and having an opening in its bottom side, a pan mounted on aside of the casing opposite the opening formed in the bottom'side thereof, a plate closing thea-ear end of the casing, a centrally disposed tube kcarried by said plate, a genf erat-ing coil within the casing includingrloops having their forward ends pointed, andhollow castings connecting the legs ofthe respective. loops and` provided with cleanout openngsin line with thelegs thereof, and plugs closing. the said clepanout openings andcon i Yso
