the room when the fuel is being fed through the door M, I preferably connect the latter by a link or arm N to a gas escaping valve or door N. Thus, when the door M is opened the valve or door N will be simultaneously opened and if there is any gaspocketed above the fire box it will pass directly into the drum portion 0 of the stove. The latter is connected to the combustion chamber by a conduit P above whicha suitable baflle plate P is located. The purpose of the latter is to compel the heat products of combustion to pass outwardly adjacent to the heat radiating surface of the drum, and if desired an oven Q can be positioned within the drum, access to this oven being had through a hinged door Q.

Describing in detail the construction of the grate G, it will'be noticed that the latter comprises a plurality of inclined surfaces G between which are a plurality of openings Gr controlled by a sliding grate B. At

its center this grate slides over aplate It secured to the main portion of the grate by suitable chair-bolts R It will be noticed that the movable member R of the grate has spaced apertures adapted when the grate pull S is drawn forward to register with the apertures in the grate G, and thus permit the ashes to pass into'the pan or tray E. The movable member It is normally held in closed position by means of a spring R while from its upper surface there projects a plurality of pins B or other agitating members adapted to loosen the ashes so as to cause them to pass through the grate. As the combustion is so complete'in this device that there areno clinkers formed andv the ashes are in the form of a fine powder, a

grate of this character is peculiarly adapted to my device and by locating the movable member at the bottom any binding of the 1 parts through ashes getting beneath the movable member is avoided.

At the lower end of the combustion chamber there is an opening T controlled by a mixer valve T, the purpose of this opening and valve being to supply an additional amount of air to the mixture in the combustion chamber. In order that there will always be a supply of air in the lower chamber D the valve U controlling the air inlet o ')enings U is normally held open by a spring, such as V Passage of air through the opening vT is however adjustably controlled by the valve T. lVhile I have shown a valve of the butterfly type, a gate or other suitable valve .could of course be employed.

The air that passes through the fuel to form thecombustible mixture is fed into the air chambers K through apertures controlled by the slide Z, each of which are provided with operating handles or knobs Z. Thus the air is fed laterally into the fuel, through the fuel, and into the combustion chamber, and is there augmented by an additional supply of air in a manner similar to a Bunsen burner. There an intense heat is generated which passes up through the conduit P, that forms an extension of the combustion chamber, and from the latter is discharged into the drum, though it is obvious that from the extension P they might be delivered to a laterally extending pipe or an oven positioned at the side or elsewhere if desired. p

The balfie plate P is supported on a plurality of legs, and after passing the bafile plate the products of combustion will be discharged through the flue outlet Y. A suitable sight opening or peep hole W covered with mica. or the like is employed so that the operator can tell without opening the stove if the proper combustion is taking place. In the normal operation of the device, there should be such complete combus tion that practically no smoke or soot reaches the flue opening Y.

Also as previously mentioned any escape of gas into the room is avoided by the automatically controlled valves or door N, which may be positioned either above the fuel hopper as shown at the left in Fig. 1 or in the extension P as shown at the right ofthis figure. In either case the valves or doors N will be located in different vertical planes than the fuel hoppers so as to avoidany danger of fuel being thrown through the doors N. In assembling the parts the three sections of the main combustion chamber wall I, are held in place at their upper ends by a flange W formed on the lower edge of the sections of the extension P. The latter is also formed in sections as shown in Fig. 3, the sections of this member being locked together by securing members Y.

The invention however is not limited to these features of construction except as speci fied in the claims, and while I have shown and described the invention as applied to a stove it is not limited to such use, since in its broader aspects it applies also to furnaces, boilers, car heaters and other fuel burning devices.

What I claim as my invention is:

1. In a fuel burning device, the combination with the fuel chamber, of a combustion chamber located centrally of said fuel chamber, an air chamber outside of said fuel chamber, there being openings for permitting air to pass laterally from the air chamber through the fuel chamber to the combustion chamber, and a normally closed grate beneath said fuel chamber and air chamber,

said grate being adjustable to provide open ings through which finely divided ash can. be removed from the fuel chamber and the air chamber.

2. In a fuel burning device, the combination with the fuel chamber, of a combuseaaaeo tion chamber, an air chamber outside of said fuel chamber, there being openings for permitting air to pass laterally from the air chamber through the fuel chamber to the combustion chamber, and a normally closed grate beneath said fuel chamber and air chamber, said grate being adjustable to provide openings through which finely divided ash can be removed from the fuel chamber and the air chamber, said grate having an upper stationary part and a lower movable part.

3. In a fuel burning device, the combination with an outer Wall, an inner Wall and a central Wall spaced from each other a su$ cient distance to provide a combustion chamber, a fuel chamber outside of said combustion chamber and an air chamber outside of said fuel chamber, said combustion chamber having an outlet for the heated gases, and an air inlet at its lower end, said Walls being provided with apertures to permit a transverse draft from the air chamber, through the fuel chamber to the combustion chamber, the draft apertures being arranged to prevent the discharge from the air chamber of ash or dust through such apertures, and means for cleaning the air chamber from ash or dust.

In testimony whereof laifix my signature.
