, OIL BURNER,

Application filed October 31, 1921. Serial No. 511,575.

burners and has'for one of its objects to produce a burner of this character which is efficient in operation, compact and easy to install without dismantling or in any way injuring a stove or the like.

Another object is to produce a burner of this character which is equipped with a new and improved type of flame spreader which is highly efficient in spreading the flame over a large area.

A still further object is to produce a generator surrounding the jet orifice on three sides and thus lead to a more certain generation of gas.

A still further object is to produce an oil burner of simple, durable, efficient and inexpensive construction; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which:

Figure 1 is a side view of a burner embodying the invention as it will appear when ready for operation within a stove or the like, the latter being broken away to clearly indicate the positions of the parts.

Figure 2 is a top plan view of the burner and its connections.

Figure 3 is a section on the line III-J11 of Figure 1.

Figure 4: is a section taken on the line IVIV of Figure 3.

Figure 5 is a section on the line VV of Figure 3.

Figure 6 is a side view of amodilied form of burner as it will appear when in operative position within a stove.

In the'said drawing, where like reference characters identify corresponding parts in all of the Figures, 1 represents the grate of a stove or the like, 2 the front wall thereof, 3 the fire box door, and 4 the ash pit opening which, it will be understood is shown convenientionally but in practice may be of any common or preferred type or construction' The burner consists of a hollow rectangular shaped generator 5 providing a fuel -receiving and gas generating chamber 6 although it will be understood that the generator may be round, square, oval or of any suitable shape. Communicating with the generator through the bottom thereof is a fuel supply pipe 7. A pair of screw plugs 8 are shown in the drawing to close a pair of openings in the side walls of the generator, formed during the process of casting, although it will be apparent that these plugs form no part of the invention and that other methods of manufacturing the generatormay beadopted if found desirable.

Communicating through one side wall of the generator with the interior chamber at its upper end is a short length of pipe 9 which, through a short pipe section 10 and a pair of elbows 11' communicating with a short pipe section 12 closed at its end by a cap 13 and formed with a jet orifice 14 substantially in the vertical axis of the generator for the discharge of gas and, under certain conditions, of oil, as will hereinafter appear. l

At the upper end'of the hollow rectangu-' lar portion of the generator. thefwalls thereof are pressed inwardly as at 15 in order to form a ledge or shelf for the supportof a deflector plate 15 formed with a pair of downwardly depending substantially V- shaped flame Spreaders 16 of the same width as the generator. In this connection it is desirable to notev that this type of deflector has been found to give the greatest satisfaction and to be highly eflicient in shooting the flame out angularly and distributing it widely within the fire box for the better and quicker radiation of its heat. These deflectors also protect the sidewalls of the generator from excessive heat to prevent the formation of carbon within thegenerating chamber. It will be noted also that the spreader plate 15 does not'closely abutthe top of the generator and thus protects this portion of the generator from interior carbonization.

.A shallow pan or'receptacle 17 is adapted to rest on the lower arm of the hollow rectang ular portion of the generator and be held reliably in position by two pairs of ears 18, embracing the generator at opposite sides of each upright vertical arm thereof,

as illustrated. It will be evident that with 1 this construction, the pan may be readily removed for cleaning by slightly tilting the same, and that in practice it is desirable to place a few ashes or the like in said receptacle to absorb and retain the liquid fuel which is permitted to drop therein from the jet orifice in the starting of the burner, as is hereinbelow set forth.

The fuel inlet pipe 7 leads downwardly through the grate and preferably out through the ash pit door or other opening 41 and communicates with a three-way elbow 19 having one of its legs in communication with a drain cook 20, the other leg of the elbow being in communication with a fuel supply pipe controlled by a hand valve 21 of any suitable or preferred character, which for convenience of illustration and operation of the device, is illustrated as dialequipped so that the relative amount of fuel flowing to the burner may at all times be determined.

The device, as illustrated, in Figure 6, consists of a generator 22 consisting of a tubular or oval pipe sect-ion resting on the grate 1 and in communication with an oil feed pipe 23. Communicating with the upper end of generator 22 is a pipe 24 which by means of a pair of elbows 26 and a short length of pipe 25 communicates with a short pipe section 27, closed at its end by a cap 28 and formed with a jet orifice 29, as illustrated. In order to provide a convenient flame spreader, one end of pipe 25 is externally threaded as at 30, and screwed on said threads is a plate 31 of such size as to efficiently spread the flame in all directions and cause a certain portion thereof to play on the walls of the generator to vaporize the liquid fuel, as will be readily understood. A pan 32 for starting the generation of gas will preferably rest directly on the grate.

The operation of the burner is, as follows: The valve 21 is opened and liquid fuel under pressure or gravity is permitted to flow into the generator until the generator is filled and a small quantity of oil has run out of the jet orifice into the pan 1?. The

' flow of oil is then stopped by means of the valve 21 and the oil standing in the pan 17 is ignited. The heat of this burning oil will be sufficient to start .the generation of gas within the pipe 12 and generator, and as soon as gas has been generated and commences to burn at the jet orifice, the valve 21 is reopened to permit ofthe continuous supply of fuel to the burner so that its operation shall be uninterrupted. It has been found that in actual operation the liquid fuel will stand at about the dotted line in Figure 3, the rest of the space above such point being filled with gas. The gas flame rising from the jet orifice will impinge directly on the spreader 15 and part of it will then be deflected outwardly by impingement on the V- shaped deflectors 16 and spread over a large area, as will be readily understood.

The operation of the type shown in Fig ure 6 is substantially the same, that is, the flame is caused to spread horizontally over a large area by contact with the spreader 31 and impinges on the generator and pipe 25 and thus maintains the same at a vaporizing temperature.

From the above description it will be apparent that I have produced a device of the character described, which possesses all of the features of advantage set forth as desirable, and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim 1. In an oil burner, the combination with a generator, of a flame spreader detachably mounted at the upper end of said generator, a pair of V-shaped deflectors underlying said spreader, and a discharge pipe having a jet orifice in substantial vertical alinement with the axis of said flame spreader.

2. In an oil burner, the combination with a generator, of a flame spreader detachably mounted at the upper end of said generator, a pair of V-shaped deflectors depending therefrom, a discharge pipe having a jet orifice in substantial vertical alinement with the axis of said flame spreader, and a starting pan detachably supported in the lower end of said generator opening below said discharge pipe.

3. In an oil burner, the combination with a generator formed with an opening having its walls near the upper end of said opening bowed inwardly to form a pair of ledges, a detachable flame spreader supported by said ledges, and a discharge pipe having a jet orifice in substantial vertical alinement with the axis of said flame spreader.

4. I11 an 9il burner, the combination with a generator formed with an opening having its walls near the upper end of said opening bowed inwardly to form a pair of ledges, a detachable flame spreader supported by said ledges, a pair of downwardly depending V- shaped deflectors formed on saidspreader, and a discharge pipe having a jet orifice in substantial vertical alinement with the axis of said flame spreader.

In witness whereof I hereunto aflix my signature.

ALBERT n. Anoox.
