Application led August 6, 1914. Serial No. 855,461.

T 0 all Lo/wm t may concern Be it known that l, ERNEST R. JACKSON, a citizen of the United States, residing at Mena, in the county of Polk and State of Arkansas, have invented a new and useful Hydrocarbon-Burner, of which the following is a specification.

The present invention appertains to liquid fuel or hydrocarbon burners, and aims to provide a novel and improved device of that character.

The present invention comprehends the provision of a hydro-carbon burner embodying a unique assemblage of parts, whereby the burner structure will be comparatively compact, substantial, inexpensive, and capable of ready assemblage and separation, and whereby the burner will be eflicient in its use.

It is also the object of this invention to provide a hydro-carbon burner embodying a peculiar assemblage of a retort or generator and a burner body, to carry out the desired objects in a satisfactory manner.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the conibination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein z- Figure 1 is a plan view of the improved burner, a portion of the supply pipe being broken away. Fig. 2 is a longitudinal vertical section of the burner taken on the line 2 2 of Fig. 1. Fig. 3 is a longitudinal section of the retort or generator taken on the line 3 3 of Fig. 1. Fig. 4 is a cross section of the burner taken on the line 4--4 of Fig. 2.

ln carrying out the present invention, there is provided a tubular or hollow cylindrical burner body 1, which has its ends open, and which is preferably cast from suitable metal. The burner body 1 is disposed horizontally and is provided with a plurality of rows of upper apertures or outlet orifices 2, which are preferably surrounded by bosses opstanding from the burner body 1, as clearly seen in Figs. 2 and a. The front row of apertures or oriiices 2- is preferably at a lower level than the others, as seen in Fig. 4t.

Cast metal caps 3 and 4 are slipped or engaged over the ends of the burner body l, and are secured together by a pair of longitudinal tie or draft rods 5 terminally en` gaged through the caps 3 and 4t and disposed adjacent the front and back sides of the burner body, as seen in Fig. 4. The tie or draft rods 5 have nuts or other securing elements engaged upon their ends, as clearly seen in the drawing, whereby the burner body 1 will be clamped securely between the caps or heads 3 and 4. The caps 3 and a are provided with lower legs 6 for supporting them upon a grate, or other surface upon which the burner is to be set. rlhe rims of the caps 3 and 4 are also pr vided with upstanding standards 7 which are inclined forwardly slightly, as seen in Fig. d, and which are located adjacent the ends of the rear row of outlet apertures 2.

The burner body 1 is provided along its front side with an integral priming cup or gutter 8, which is coextensive with the outlet apertures 2, and which is located directly below the forward row of apertures, as seen in Fig. 1.

The cap 4 is provided with an outstanding tapered nipple 9 having the air openings or inlets 10 in its sides, and a tubular nozzle or mixing tube 11 projects axially g into the burner body 1 from the cap a, and has its outer end threaded into the nipple 9 to communicate therewith. rlhe free end of the nipple 9 is provided with upper and lower notches 12 for the purpose which will hereinafter appear.

The retort or generator for vaporizing the liquid fuel, embodies an elongated and relatively flat casting 13 disposed longitudinally above the rear side of the burner 1, and resting against the standards 7, screws or other securing elements 13El being engaged through the standards 7 and taking into the end portions of the retort casting 13 to clamp the same against the standbores 14 and 15 extending therethrough, and with an inclined or diagonal bore 16 connecting opposite end portions of the bores 14 and 15. That end of the lower bore 14 adjacent the lower end of the bore 16, is plugged or stopped up by a screw plug 17, while the liquid fuel supply pipe 18 is engaged or threaded into the other end of.v the bore 14, and is provided with a suitable controlling valve 19. The liquid fuel supply pipe 18 may lead to a tank or other suitable source of liquid fuel, and the liquid fuel may be supplied by gravity or under pressure, which ever is desired. That end of the upper bore 15 of the retort casting adjacent the upper end of the bore 16, is stopped up by a screw plug 20 threaded thereinto, and an outlet pipe 21 for the retort is threaded or otherwise engaged in the other end of the bore 15 opposite the supply pipe 18 and has a depending arm 22 seated within the notches 12 of the nipple 9 to hold the arm 22 in place. The lower end of the arm 22 is closed by a cap 23, and the outlet arm 22 is provided with an aperture 24 coaxial with and leading into the nipple 9.

As will be apparent, the burner body 1, caps 3 and 4, and the retort body 13 are each cast from metal, whereby they may be inexpensively manufactured. Furthermore, the component parts of the burner may be readily assembled, and provide a compact and desirable structure..

In operation, when the controlling valve 1.9 is opened, the liquid fuel will be permitted to flow into the lower longitudinal bore 14 of the retort, and a small quantity of combustible material or liquid may be placed or poured within the priming cup or channel 8 and then ignited so as to prime the burner, it being noted that the matter within the priming cup or channel 8 being ignited, will serve to heat the retort to thereby start the vaporization of the liquid fuel within the retort. As the liquid fuel becomes vaporized within the bore 14 of the retort, the same will pass upwardly through the inclined bore 16 into the upper bore 15, in which the vapor' will be superheated, and the superheated vapor will then pass outwardly through the outlet pine 21 of the retort and through the aperture 24. The vapor being discharged through the nipple 9 from the aperture 24, will draw air through the air inlets 10 of the nipple, and the vapor and air will then be thoroughly admixed within the mixing tube or nozzle 11, and ejected into the burner body 1. 1Within the burner body 1, the mixture will be thoroughly agitated and will pass upwardly through the outlet apertures 2 to support the flames. The flames will then serve to continue the vaporization of the `liquid fuel within the retort,l which retort will be heated by the iiames and the ames will also serve to heat the boiler, furnace or other structure to which the device is applied. The other advantages and capabilities of the present invention will be obvious to those versed in the art, without extensive comment being necessary.

Having thus described the invention, what is claimed as new is l. In a hydro-carbon burner, a hollow burner body having upper outlets, caps engaged over the ends of the burner body, one cap having an outstanding nipple provided with an air inlet, a retort secured to the said caps, and an outlet pipe connected to the retort and having an arm provided with an aperture communicating with the nipple, the free end of the nipple having notches receiving the said arm.

2. In a hydro-carbon burner, a hollow burner body having upper outlets and an elongated priming cup along its forward side, caps slipped over the ends of the burner body and having standards, tie rods connecting the caps, one cap having an outstanding nipple provided with air inlets and having notches at its free end, a nozzle threaded into said nipple and projecting into the burner body. a retort secured to the said standards above the rear side of the burner body and having bores therein, and an outlet pipe secured to the retort to com municate with the bores thereof and having an arm seated in the said notches of the nipple and provided with an aperture communicating with the nipple.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
