After suiiifrom the casing 1 and forms a passage 8 becient headway has been obtained the damper tween the drum and stove-casing. This drum 26 is closed, and the products of combustion is concentric with the casing 1, and the lower will then pass into the apertures 17 and exportion thereof is so shaped as to permit of tensions 18 and will come into contact with convenient access to the door 9 of the ashshields 23, whichwill direct them downward into the drum 7. then circulate through the drum and thoroughl y heat all the surfaces thereof and will then pass through the outlet into the receptacle 11 and thence outward by way of the outlet-pipe 14 to the Stovepipe 15. It will thus be seen that the surrounding air upon coming into contact with the faces of the drum will be thoroughly heated, and a draft will be established through the passage 8, which will result in the rapid heating of all the air confined in a room with this stove. Any soot or other solid materials which may accumulate within the drum can be readily removed by detaching the heads 12 and 29. The drum itself can be quickly removed by detaching the inlet-tubes from the extensions 18, after which it can be raised from the supporting-brackets 5.

It will be seen that the device is vey simple in construction and very effective for heating purposes and that practically all of the heat generated is utilized.

In the drawings 1 have shown by arrows the circulation of air and products of combustion through the apparatus and the circulation established by the surrounding air through the passage 8.

These hot products will In the foregoing description I have shown the preferred form of my invention; butI do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as new is In a device of the character described, the combination with a stove; of a detachable drum inclosing and supported by the stove, said drum being spaced from the stove to form an air-passage, detachable tubular connections between the drum and stove and forming outlets from the stove to the drum, shields within the drum and adjacent the connections, an outlet from the drum, and means for directing products of combustion into the drum.

In testimony whereof I afiix my signature in presence of two witnesses.
