Still .anf additional object-.is 'to provide a .novel burner structure. I

Witlnthese andro-ther Aojrij'ec'ts in view, my

invention: consists in @the-,-c`onstruotion, ar-

rangement :and ,Combination [of the various partsgof finywdeviceL-wherebytheects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical, central, sectional view through an oil burning furnace embodying my invention.

Figure 2 shows a detail, sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail, sectional View taken on the line 3-3 of Figure 1.

Figure 4 is a detail, sectional view through a portion of the bottom of the furnace; and

Figure 5 shows a detail, sectional view through a slightly modified form of the bottom.

In the drawings herewith, in which one form of my invention is illustrated, I have used the reference numeral 10 to indicate generally the casing of the furnace or stove.y

12, 'which may be made "of Alire clay,='a1s Vshown for instance inFigures land 4- or as shown at 13`-1n Figure 5, where the-fire`boX vrbottom 1s made lofgrate iron.

V1"Vzll'here the casing is -madefof thin steel,

for instance, I preferably-line it' above the bottom 1l for arsubstantialdistance 'withfire brick' 1:4. v

The casijn'gmay bemade* Ofany L'suitable material,V cast 3 firo'n or otherwise, that f is adaptcd'forithe purpose. Y

' I-:providethe bottom -12401 13,as the )case K4may be, morder toprotectthe concrete ibot- -toinl 11 from the intense heaftfwithin tlre fire box Yportionof thel casing. y

The casing 10 is providedA with V-a door 15 4in its side wall to permitI readyaccesstofthe interior o'f the furnace .or `stove.

"Mounted-"in-the bottomfofithe'stoveeis a receptacle or reservoir 1G, the lower---endif 'which projects 'below 'thebottorn11l alndis jnov'idedwith ascrewcap 117 for clean-out purposes. y l

Connected Viwith 'the cap.` L17 by a visuitable Extendingupward fronifthe upper' end :the reservoir or "receptacle 1G` is a short "pipe-19. on which is a' T--niplple20- Screwed The upper face or surface of the bottom l 12 is concave as at 23. The same configuration is found in the modiiied forni of the bottom shown at 13 in Figure 5.

Connected with the nipple 2O is a drain pipe 24 extending to a point outside the casing 10. The drain pipe 24 may lead to the sewer or to any suitable receptacle to take care of overflow.

An air supply pipe 25, the size of which is determined by the size of the furnace or stove and by the heating problem involved, enters the casing 10 at the top or any suitable point and has a portion eX- tending downwardly and terminating just above the spreader flange 22. One or more hot air pipes 26 may lead oif from the upper portion of the casing 10. Braces 27 may be provided for the pipe 25, if desired.

It will, of course, be understood that suit-Y able control valves are provided for the fuel and that the pipe 19 is connected with a source of fuel supply.

In the practical use of my improved furnace or stove, the oil, such `as kerosene for instance, is supplied through the pipe 19 to the reservoir 16 and will then flow upwardly to the burner nozzle. f

A small amount of oil may be ignited in the concave portion 23 of the bottom 12. After it is burned a short time, the conductivity of the bottoms 12 and 11 is such as to cause a gas to be generated, so that when the flow of oil is properly regulated only agas will be burned.

The air flowing in through the pipe 25 will be directed downwardly against the open end of the nozzle and the spreader flange 22 and the flame will thus be directed downwardly and outwardly.

The flame will thus be properly spread and the gas will burn with an intense heat.

The concrete bottom 11 is protected against overheating and consequent disintegration by the bottom 12 or 13 as the case may be.

The amount of heat generated can, of course, be regulated by controlling the flow of fuel.

In case the fire should go out or in case the fuel should be permitted to flow to the nozzle when the fire is not burning, the furnace or stove will not overflow 4and be flooded with oil, but the oil will be held by the concave portion 23 and will flow back through the nozzle 21 to the drain pipe 24. The drain pipe 24 is provided with an upward bend 28, which stands at a height practically Hush with the upper discharge end of the nozzle 21 for thus preventing the flooding of the furnace or stove.

It will, ofcourse, be, understood that the size of my burner may be varied as may be desired; that the size of the pipe 25 is determinedby the number of cubic feet of rooms to be heated; and the size and number of the pipe or pipes 26 is determined by the heating problem.`

The device mayv be readily made in the form of a furnace or to serve as a heating stove. Any material suitable for the pur pose may be employed in any of the parts of my improved oil burning furnace or stovestructure, and I intend to cover by the claims of my patent any modified forms of structure or use of mechanical equivalents or employment'of a variety of material or changes in shape or size, which may be included within the scope of such claims.

I claim as my invention:

In a structure of the kind described, a casing, a bottom therefor, a fire box bottom above said first bottom, having a concave upper surface, a burner nozzle located within such concave portion, to discharge at a. point below the periphery thereof, a reservoir below said nozzle and in communication therewith, located substantially below the upper surface of said fire box bottom and belowv thel point of combustion ofthe burner so as to be free from sufficient heat to disintegrate the fuel, but to be warmed duringthe operation of the device.
