Application filed February 2, 1916. Serial No. 75,720.

.To all whom t may concern:

Be it known that I, Louis J. ScHn'r'rL, a citizen of the United States, residing at liffanitowoc, in the county of Manitowoc and State of `Wisconsin, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to hydrocarbon burners, and has particular reference to a burner for oil or other hydrocarbon fuel in which the oil is vaporized and mixed with sufficient quantity of air to support combustion and burn the gas.

The invention provides a burner which will generate steam to be used for mixing with the hydrocarbon to produce a gaseous fuel which will burn with a clear flame and be free from carbon.

The invention further consists in the provision of a burner head, fuel and water supply tanks, and pipe lines connecting the tanks with the head, the pipe lines from each of the tanks having coils formed therein and arranged in advance of the burner head so that the jet of flame issuing` from the head will heat the coils and vaporize the fuel and water therein so that the fuel will be sup plied to the head in a highly volatile state and also the water in the form of steam. Compressed air is supplied to the tanks for feeding the fuel and water to the burner from any desired source, and it is another object of the invention to provide means whereby the pipe lines between the tanks and burner head may be cleaned by the use of such air.

A further object of the invention is t0 provide a novel and efficient form of burner ti PA still further object of the invention is to provide a burner of this character which is extremely simple in construction, cheap and easy to manufacture, and which is thoroughly reliable and efficient in operation.

With the foregoing and other objects` in view, the invention consists in the novel features of construction, combination and arrangement of parts, as will be hereinafter, more fully described, illustrated in the accompanying drawings, and claimed.

1n the drawings Figure 1 is a side elevation of the complete burner. Fig. 2 is a top plan. Fig. 3 is a detail longitudinal section through the burner head. Figyll is a detail section through the burner tip; and Fig. t5. is a plan of one of the plugs of the burner Referring to the drawings by numerals, wherein is illustrated the preferred embodiment of my invention, 1 designates a suitable supporting structure which has sup` ported thereon in any suitable manner, as by the brackets 2, oil and water tanks 3 and l, respectively, the said tanks being of any desired capacity and being arranged adjacent each other in spaced relation. Each of these tanks is provided with a filling opening at its upper end, which is closed by a cap 5, while the water tank 4: is provided at its lower end with a drain pipe 6 which may be provided with a suitable valve to permit the draining of this tank.

Gages 7 and 8 are arranged upon the oil and water tanks respectively, and are of the usual construction. From the lower end of the gage 8 extends a pipe 9 which has arranged therein a T-fitting 10. This pipe 9 then extends upwardly and is connected with a pipe line 11 carried by the burner head, indicated in its entirety at 12.

The burner head 12 comprises a cylindrical tube 13 of any desired size and which is preferably closed at its rear end. Within the tube 13 near its front end and extending diametrically across the same is a hollow member 15, preferably cylindrical in shape and having a central diaphram l5L dividing it into two chambers 14 and lta. The ends of the member 15 each have an opening therethrough communicating with one of the interior chambers as illustrated in Fig. 4. Openings 13a and 13b similar to the openings in the member 15 are formed in the sides of the tube 13 and coincident therewith for a purpose to be described later. The member 15 is provided on its forward side with two projecting nipples 16, the bores 17 of which communicate respectively with the chambers 14 and 141a and incline toward each other. Short tubes 18 are threaded in the bores 17 and at their outer converging ends carry caps 19. Each of the caps 19 is preferably threaded upon the outer end of a tube 18 and is provided with an internally threaded bore to receive plugs 20. These plugs are provided with any desired number of radially extending slots 21 which are preferably arranged diagonally of the longitudinal extent of the plugs so that gas or fluid issuing Cpt therethrough from the tubes 18 will be given a rotary or twisting motion, as will be understood. v

The pipe 11 extends longitudinally along the outer face of the tube 13 and is supported thereon by means of brackets This pipe extends beyond the open end of the Y rearwardly, as at 24, and is threaded in the Vopening 13b in the tube 13y and into one of the end openings of the member 15. A needle valve 25 is arranged in the pipe line 11 between the coil 23 and tank el. in order to adjust and vary the supply of water to the coil23. Y

A' pipe 26 is connected at one'end with the fitting 10 and at its onpositeend with a four-way fitting 27. `This pipe is arranged parallel to the tanks, and intermediate its ends is provided with a. T-fitting 28 to which is comiected one end of apipe 29, its opposite end-being connected with an air compressor of any suitable type. The fitting 27 Y is further provided with a short pipe 30 upon which is arranged a pressure gage 31. Pipes 32 and 33 also connect the fitting 27 with the tanks 3 and it respectively, a valve 3J: being arranged in the pipe 32 as is clearly illustrated in F ig. 1 of the drawings.

The pipe line 9 is provided wit-h a valve 35 arranged therein between the fitting 10 and the gage 8, while the pipe 2G is provided 'with a valve 36' arranged therein between the fittings 10 and 28.

Communicating with the lower end of the gage 7 of the oil tank is a pipe 37 which extends upwardly from the gage and communicates with a pipe 38 arranged longitudinally of and supported by the tube 13 by means of brackets 39. This pipe is arranged upon the opposite face of the tube 13 from the pipe11 and is extended forwardly of the open end of the tube where it is formed into a coil Ll0. Thiscoil 40 extends at substantially rightV angles to thefpipe 38 and is arranged in advance of the open end of the tube and between such open end and the coil The opposite end of this coil is extended rearwardly, as at 41, and is threaded into the opening 13 upon the opposite face of the tube 13 to that with which the pipe 24; is engaged. VThis pipe L11 communicates with the adjacent threaded endof the member 15. i needle valve 42 is arranged in the pipe line 38 between the coil and the gage and is adapted to Vbe adjusted toV vary the supply of oil to the burner head, while asecond valve 43 is arranged within this pipe line whichis adapted to be operated to open or 'entirely cut off the supply of fuel from the f tank 'to' the burner.

amount of air to the tube to mix with the fuel issuing from the burner tip to support combustion and provide for the proper burning of the fuel.

In operation, the valves and i3, in the pipe lines 9 and 37, respectively, are opened and the needle valves 25 and .42 adjusted to permit of the proper quantity and proportion of water and oil being admitted to thel coils 23 and 40 respectively, air under pressure from the compressor having first been supplied to the tanks to cause the water and oil to be forced through the pipe lines. Au initial lighting of the fuel at the burner tip is accomplished in any desired manner and the jet. of fiame issuing therefrom will heat the coils and cause t-he oil and water therein to be heated and become vaporized, where.- upon the pressure created in the coils by such vaporization will cause the gas and` steam thus formed to pass to the respective chambers 1land 14C of the member 15 and out through the tubes 18 and diagonally extending slots 21, which latter tend to givrthe flame a rotary motion. A sufiicient amount of air is drawn through the openings elel. in the tube 13 to support proper combustion at the burner tip.

From the foregoing it is thought that thi` construction and operation of the improved burner will be clearly understood.

I have so arranged the several pipe lines and the valves therein that the water tank may be drained as well as the water suppl): pipes to prevent bursting of the tank or pipes in cold weather. By first opening the valve in the drain pipe G, the contents of the tank may be drawn off. However, thisy draining of the tank will not drain the water from the water pipes and therefore, I hav(` so arranged the several valves that air under pressure from the air compressor ma \v be utilized for cleaning these pipes out. After the water has been drained from the tank the valve in the drain pipe 6 is closed.

as is the valve 3ft in the pipe 32. This causes air from the air compressor to travel to the tank, valve 36 in the pipe 26 having first been closed and the valve 35 opened so that such air will travel out through the gage 3. through the pipes 9 and 11, coil 23, pipe 2i. and out through the burner tip which will force allwater and foreign matter from the pipes. If it is desired to clean the pipes merely without drawing off the contents of the tank, the valve 35 may be closed and the valve 86 opened whereupon the air will travel downwardly though the pipe 26 and thence through the pipes 9 and 11, coil 23, pipes 24- and through the burner tip.

F rom the foregoing description taken in connection with the accompanying drawings, it is thought that the construction and operation of my improved burner will be readily understood and while I have herein shown and described one preferred embodiment of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim:
