LIQUID-FUEL BURNER.

' Application .filed May a,

the invention, such as will enable others skilled in the art to which it appertainsto make and use the same. v

Thisinvention relates to new anduset'ul improvements in burners and particularly to burners for vaporizing and burning liquid fuel, such as kerosene.

One object of the invention is to provide a burner which has novel and improved means for supplying air, for combustion, to the escaping gas, and at the same time to direct the air and gas against the generator pipes.

Another object is to provide a device of this character wherein the heat from the flame of the burning fuel is. absorbed by a porous material which is so arranged as to radiate its heat with the maximum efli ciency.

Other objects and advantages will be apparent from the vfollowing description when taken in connection with the accompanying drawing.

In the drawing: I t

Figure 1 is a side elevation of a burner made in accordance with the invention.

Figure 2 is a top plan view of the same.

Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 2, showing the gas openings, and the air openings with their directing wings.

Referring particularly. to the accompanying drawing, 10 represents a pan having its bottom upwardly arched, throughout its length, as shown at 11, and secured to the lower face of said bottom are the transverse bars 12, which are adapted to rest on the bars of a cook-stove grate, the bars being riveted to the bottom of the pan 10. Extending lon-i gitudinally of the pan, and resting in notches 13, in the upper edges 01 the ends of the pan, are the side pipe portions 14, of the generator 15, the ends of the pipe portions being connected by the transverse pipes 16 and 17, respectively, whereby. a rec- 1922. Serial no. 557,883.

tangular frame isthus formed. Connected tothe pipe 16, in the lowersidethereof, and

extending longitudinally "in parallel, relation to the pipes 14, but beneath the arched bottom of the pan, is the burner pipe-.18,

the other end of said pipe terminating adj acent the other transverse pipe 17', asjclearly seen in the plan view, Figure 2. Connected to-the outer side of the pipe 1'? is a'liquid fuel conductor 19, which conveys fuel to. the generaton and leads from any suitable source, not shown. 7 r s "In the pipe 18, adjacent each end, and above a horizontal line drawn through the pipe, are the gas outlet or burner openings 20, said openings being formed by boring,

- from-the outer face of the pipe to a distance approximately three-quarters ofthe thick ness of the pipe, and then drilling a very small hole 20 in the center of the .bottom' of the thus bored recess'or opening 20. It .will be noted that these openings are disposed in such position that the flame which issues therefrom, is directed against the side pipe 14. In the side walls of the arched bottom, above each of the openings 20, there is formed an opening 21, the upper and lower portions of the walls thereoitbeing bent outwardly and upwardly toward the side pipes 14, so that the gas from the openings 20 will pass therethrough, while the air from beneath the pan, will also. pass upwardly through said openings, and mix with the gas, to aid the combustion thereof.

Disposed transversely of the generator, and having their downwardly curved ends 22, resting on the side pipes 14, are the bars 22, thesaid bars supporting the firebrick -23 thereon. Between the side walls .24, of the fire-pot 25, and the sides of the fire-brick 23, broken fire-brick pieces 26.

The flames from the openings 20 rise againstthe side pipes 14, heating said pipes so as to cause the vaporization of the liquid fuel which passes through them, on the way to the burner pipe, 18, and travels or rises upwardly to heat the fire-brick 28, as well as the broken fire-brick 26. Theheat absorbed by these bricks, and then radiated therefrom, serves to produce a sufliciently high temperature to permit heating of water in the water tank and cooking or baking in the oven, as well as cooking on the top of the stove. When thebricks have become heated to a high temperature, the flow of liquid fuel can be checked, with the consequent saving of fuel.

What is claimed is:

1. A heating device including a pan, an arch in the pan formed with openings in the sides thereof, outwardly extending air and gas directing wings in the openings, a generator above the arch, a burner disposed beneath the arch and having openings positioned to discharge flame through the air openings, and heat absorbing means'supported on the generator.

2; A heating device including a pan having a transversely arched bottom formed with openings in the sides thereof, outwardly extending air and gas directing wings in the openings, a generator supported on the pan above the arched bottom, a burner disposed beneath the arched bottom and having openings positioned to discharge flame through the air openings, and heat absori ing and radiating means supported on the generator.

3. A. heating device including a pan, a generator supported on the pan, a burner beneath the pan, the pan having air and gas openings, means for supporting the pan on a stove grate, transverse bars on the generator, a heat absorbing and radiating member supported on the bars, and broken heat absorbing and radiating means at the sides of the first heat adsorbing and radiating means.

In testimony whereof, I a'iiix my signature, in the presence of two witnesses.
