T @ZZ whom, it 'hi/ty concern:

Be it known that we, FRANKLIN M. REED, of Indianapolis, county of Marion, and CORNE- LIUS R. UMBENHOWER, of Pendleton, county of Madison, State of Indiana, have invented a certain new and useful Heating-Stove; and we do hereby declare that the following is a full, clear, and exact description thereof, reference heilig had to the accompanying draw- Io ings, in which like figures refer to like parts. Our invention relates toa heating-stove for burning gas or other. fuel.

What we claim as our invention will be understood from the following description and claims and the accompanying drawings, illustrating one form of stove embodying our invention.

In the drawings, Figure l is a central vertical section of said stove. Fig.'2 is a plan zo of the oil-pan or bottom of the burner. Fig. 3 is a plan of the diaphragm on which the burner is mounted. Fig. 4 is a section on the line A A of Fig. 1.

In detail we show herein a stove containz5 ing a base l, supported upon legs 2 and with a shell 3 extending upward from the base in which the burner is locatedand which constitutes the fuel-chamber. The shell is contin ued to form the upper part 4. These parts,

3o however, in the stove shown form one shellV with a contracted portion between the parts 3 and 4L. On the upper end of part Il of the shell the top 5 is mounted on a ring of openwork 6. 7 is the bottom of the base.

8 is the door, and 9 is the outlet to the flue. l/Vithin the upper portion of the shell of the stove we suspend an internal heatingchamber l0, pointed at its lowerend and cen- 4o tral over the burner or the fire-chamber and of less diameter than the upper shell, so that the fuelchamber surrounds said internal heating-chamber l0. This internal heatingchamber is open at the upper end to the outside air through the open-work 6. The outlet to the due is at the upper end of the outer or fuel chamber. With this arrangement, therefore, the flames and heat from the fuel envelop said internal heating-chamber and pass up around it and out through the Hue. There- 5o fore in addition to the outer heat-radiating surface we have the heat-radiating surface of said internal chamber l0, thus substantially doubling the heat-radiating surface. Another effect of this construction is that since the internal heating-chamber l0 is centrally located it drives the heat and Haine against the outershell ofthe stove, th us bringing the heat or flames in direct contact with said outer shell instead of allowing the heat 6o and flame to pass directly up through the middle of the stove and out through the due without imparting the heat to the wall of the stove, as is true of stoves in the usual form. In this stove the heat and flame in their passage up through the stove are in direct contact simultaneously with both the inner and outer shells. To render said construction further effective, means is provided for introducing air to the lower end of theinternal chamber 7o through the conduit 13, which in the form shown leads from the bottom of the shell or stove up past the lire-chamber, whereby the `air is somewhat heated before it ent-ers the internal chamber. Ve also provide a conduit l5, leading likewise from the bottom of the stove up past the fire into the upper part of thetire-chamber, whereby the air is somewhat heated and in that condition is introduced through the openings 16 directly upon 8o the dame or fuel. The wall 14 separates conduits 13 and 15. This introduction of superi heated air at the point indicated into the firechamber causes it to mix with the smoke and gases, which results in their complete combustion.

Between the base and the fire-'chamber 3 we cast an annular ring 2l, upon which we place the diaphragm 20, so that it is readily removable. Saiddiaphragmiscentrallyopen 9o and has inwardly-extending arms 22, that are provided with upwardly-extending lugs 23. Upon the arms 22 we place the bottom piece 24: of the burner, so'that it is held in 'place by the lugs 23. Said bottom is centrally apertured, and has around said aperture a sleeve 25, through which the oil-pipe 26 extends upward. Said bottom 20 has an external rim 27 and a series of openings 28 which are also protected by upwardly extending walls 29, whereby the oil cannot escape through said bottom, but air can readily pass up through it for combustion purposes.

On the upper end of the oil-pipe 26 We `mount an `outlet-dome 30, theopeningthere-E from being central, whereby.the=oilwi1l flaw@ so that the heat by the inturned top of ythef casing 32 is deflected againstthe hood 31. The hood 31 is provided with aseries of apertures 33 for thevescapeof beat and intermingling` of air and gases. 34 leads centrallyfrom the bottom `7 to carry oi any overflow of oil.

In Ithis construction of stove either foil, f

gas, or coal can be burned, as the coal-grate can `be substituted for the oil-burner herein l shown. Also the oil-burner as here made can be lifted out of the stove without disconnecting or interfering with the oil-supply pipe.

What we claim as our in ventioznand desire toasecure 'by Letters `Patent, is-

1. A stove including an outer shell centrally contracted and also contracted near its upper end, a smoke-outlet above the upper contraction, an inner casing located in the .upperapartof the `stove with the bodyof it between 'thgecontracted portions of the outer shell and parallel therewith, the upper end of said casing being open and secured to the stove Aabove the smoke-outlet and the lower end being tapering centrally over the fire-pot, and an air-inlet to the lower end of said inner chamber that 'leads from Vthe `bottom of the stove.

2. A stove including an outer shell with a fuel-chamber in its lower end, an inner cas- Aing foriningan vinner air-heatingchamber oc- ,copying the central portion of the upper end of the stove, an outletopening from `the upper end of said inner-chamber, an .air-inlet opening 'from the bottom of the stove `to the 'lower end of said inner chamber, and an airinlet into the fuelchamber just below said inner casing.

In Witness whereof we have hereunto affixed our signatures in the presence `of the witnesses 'herein named.
