WILLIAM A. WALLACE, OFJJ'OHNSTON CITY, ILLINOIS.

OIL BURNER.

Application filed November 2, 1921. Serial No. 512,247.

To all whom it may concern:

Be it known that I, lVILLIAM A. lVALLAon, a citizen of the United States, residing at Johnston City, in the county of lVilliamson and State of Illinois, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification, reference being had to the accompanying drawings, v

This invention relates to improvements in oil burners, and particula'rly to that'class of oil burners designed to be disposed within a stove.

The general object of the invention is to provide a very simple and cheaply construct ed burner of this character which may be readily disposed within the fire pot of a stove and which is so constructed as to direct jets of flame up against the lids of the stove or into the space around the oven.

A further object of the invention is to provide a construction of this character wherein the burners and the pipes connected thereto are mounted upon a base so that these pipes and burners will be held rigidly in place against shocks and jars and may be readily installed as a whole into the stove or removed therefrom.

A still further objectis to provide in a burner of this character a series of metallic rods disposed within the feed pipe adjacent the burner tip, these rods acting to hold the heat and more perfectly to vaporize the oil.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein 2 Figure l is a vertical transverse section of a stove showing my burner applied thereto;

-Fig'ure 2 is a top plan view of the burner;

Figure 3 is an elevation on the line 38 of Figure 1, looking in the direction of the arrow;

Figure 4 is a fragmentary top plan view of the valves for controlling the burner;

Figure 5 isa longitudinal section ofthe pipe 27 and connected parts;

Figure 6 is alongitudinal sectional view of the pipe 18 and connected parts;

Figure 7 is a longitudinal section on the line 77 of either'Figure 5 or F igure6;

Figure 8 is a perspective view of one of the deflectors of Spreaders;

Referring, to these drawings, 10 designates a cast iron base of any suitable length and Width, this base having a top 11 formed with the spaced depressions or wells 12 designed to contain each an asbestos mat or wick. The ends of the base are formed with the upwardly extending bosses l3. Extending upward through the base are two parallel pipes 1 iwhich at their upper ends carry elbows 15 facing away from each other.

Extending, away from each other are the horizontal pipes 16, and at the ends of these pipes are the downwardl extending pipes 17, which at their liiiwer ends carrv elbows and the longitudinally extending pipe sections 18, the pipe sections 18 extending toward each other and terminating over the wells 12. Each of these pipes 18 terminates in a cap 19 formed withan upwardly extending jetnozzle 20. Disposed within the pipes 18, as illustrated more particularly in Figure 6, are a plurality of steel rods 21. It will be understood that the pipes 16, 17 and 18 are joined to each other by elbows 15 or be constructed in any other suitable manner.

Upwardly extending through the base 10 is a vertical pipe 22 carrying a T 23 at its upper end, and from this T extend the two opposite branch pipes 24 having elbows at their ends, from which extend downward pipes 25, the lower ends of these downward ly directed pipes having forwardly directed elbows 26, from which extend forwardly directed pipe sections 27 carrying caps 28 at their ends, these caps being formed with discharge apertures or jet orifices 29 discharging in a horizontal plane, where the jet orifices 2O discharge in a vertical plane. The jet orifices 20 are designed to discharge upward against or toward the lids of the stove, while the orifices 29 discharge into the space between the oven and the top of the stove, as illustrated in Figure 1.

It will be noted that the pipe sections 27 also extend over the wells 18. The pipe sections 27 are also provided with the longitudinally extending steel rods 21 previously referred to and for the purpose heretofore described. Mounted upon the horizontal pipe 16 are the spreaders 30, these spreaders being disk-like members supported by a shackle 31 on these pipes and being norinall-y disposed over the jet nozzle 20 so as to spread the flame issuing therefrom.

The oil is primarily contained in a tank 32 provided with the usual apertured lid, and from this tank leads a pipe 33 having in its length the controlling valve 34%. The

pipe leads into a header 35, from which extend a plurality of valve casings. There are two valve casings 86 which are connected by the copper pipes 57 to the respective pipes 14. Controlling the low from the valve casings into the pipes 37 are the ne dle valves 38 having handles 39 whereby the flow of oil may be controlled. A valve casing *lO is connected to a copper pipe 4-1 which leads to the pipe 22, and within this valve casing 40 there is disposed a needle valve controlled by a handle 42. Thus it will be seen that the oil maybe turned on in either of the lid burners independently of the other lid burner or allowed to flow through the oven burners. The bosses 13 act to support the horizontal pipe sections 16 and 18.

In the use or this device, the base is disposed within a stove or furnace resting upon the grate bars thereot or in the fire pot thereof, and the relatively flexible copper pipes 32' and ii are connected to the several pipes ll and 22 and the header 35 is connected to the tank 32 by pipe 33. Air is admitted to the tire box of the stove by means of tiie usual damper valve so as to startcombustion. W'hen it is desired to light the fire, it is only necessary to open one of the valves 38 and permit a certain amount or the oil to drip down onto the asbestos mats in the wells 12. Then a match is applied to the wicks or mats and the heat will vaporize the oil in the horizontal pipes 18 and the. vapor passing out through the ct orifices 13 will ignite almost immediately. The same is true if it is desired. to light the oven burners. The valves 88 are turned on just sutficient to permit a small amount of oil to drip upon the asbestos wicks, then the valves 35 are closed oil again, the asbestos wicks are lighted and the valve 41 is turned on, whereupon the flame of the asbestos wicks will vaporize the oil in the pipe sections 27 and eventually ignite the jet issuing from the orifices 29. Once either the oven burners or the lid burners are ignited, the other burners may be ignited by simply turning on the valve or valves controlling the same, thus making it very easy to light the burners.

It will be understood, of course. that when one set or burners is turned off, the heat from the one set of burners will vaporize the oil in the pipe sections of the other set of burners. This vaporization of the oil is particularly readily accomplished through the fact that the pipes 27 and the pipes 18 are provided with the longitudinally 6X- tending, metallic rods 21. Ihese rods, which are quite closely packed within the pipe sections, act to retain heat, act to sub-divide the oil, and secure a much more perfect vaporization of the oil than is otherwise possible. 4

I have found in practice that with these steel rods disposed within the burner pipe sections that the oil is vaporized so well that very little soot is produced and a clean flame is secured. It will be seen that my burner is composed of ordinary pipe fittings so that it may be very cheaply made, that it is compact, that it may be placed as a unit within the stove or removed therefrom, and that because of the factthat it is mounted on a base the pipe fittings will not become jarred out of place. It will also be noted that while there are burners designed to discharge directly into the oven and burners designed to discharge directly up against the lids, yet when the oven burners are on they will heat the lids to some extent and when the lid heaters are on they will heat the oven to some extent.

While I have illustrated a construction which I have found in practice to be particuiarly adapted for the purpose described, I do not wish to be limited thereto, as it is obvious that many changes might be made in the details of construction and arrangement of parts without departing from the spirit of the invention.

I claim z- An oil burner of the character described including a base, pipes extending upwardly through the base, then laterally is opposite directions to the ends of the base, then downward and toward each other and terminating in burner caps having upwardly projecting nozzles, a pipe extending upwardly through the base and having oppositely directed branches, the ends of the branches extending downward toward the base and then forward beneath the burner nozzles of the first named pipes, the burner nozzles having rearwardly projecting jet apertures, the base beneath said burner nozzles being formed with wells for the reception of wicks, bafi'les disposed above the first named burner nozzles, a header,atuel tank connected to the header of the valve casings connected to the header, pipes leading from two of the valve casings to the first named pipes projecting upward from the base, a pipe leading from the third valve to the second named pipe projecting upward from the base, and valves in the valve casings controlling the passage of fuel through said pipes.

In testimony whereof I hereunto aflix my signature.

WILLIAM A. WVALLACE.
