SPECIFICATION forming part of Letters Patent No. 656,978, dated August 28, 1900.

Application filed January 5, 1900. Serial No. 495. (No model.)

To all whom it may concern:

Be it known that I, LINCOLN HOWARD, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Heating-Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in combination coal and wood air-tight heatingstoves; and the objects of my improvements are, first, to provide an air tight stove equally suited to the consumption of either coal or wood; second, that will radiate a greater degree of head toward the floor than other stoves; third, that will emit a larger amount of heat and consume a smaller amount of fuel than that emitted and consumed by other stoves, and, fourth, that will be more durable than other sheet-iron heaters and have superior entrance and draft provisions. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of the stove, showing the construction of the interior. Fig. 2 is a front View of the stove, and Fig. 3 is a vertical section of the same on the line 3 3 of Fig. 1.

Similar letters refer to similar parts throughout the several views.

My invention consists of a drum A with a flat top and inverted conical base B, which tapers at an an le of about sixteen degrees. An opening in the top covered by a hinged lid 0 affords access to the interior for sup plying the stove with fuel.

The stove at its base or front is provided with an ash-pit entrance D, having upright sides (Z d and door (1, hinged at its bottom, by which the entrance to the ash-pit and stove is securely closed. Above the door there is a revoluble damper E, the base of which is cast as a part of the casting forming an entrance to the ash-pit. A grate F, supported by brackets H H and set on a line horizontal with the top of the ash-pit entrance and divided through its center, adapts the stove to the use of coal. This grate not being attached to the stove may be easily lifted off its brackets and taken out to permit the use of wood or for any purpose.

The bottom of the stove is provided with a corrugated iron floor I, which fits in closely against the casing of the base on all sides and lies level with the bottom of the ash-pit door d, thus facilitating the removal of the ashes. Inside the conical sides of the base there is a corrugated iron partition K of corresponding shape separated about threefourths of an inch from the casing, its lower edge resting upon the corrugated iron floor.

This partition is not rigidly attached to any part of the stove and may be readily removed. Said corrugated partition is provided with a lateral flange L, formed by the top edge being bent outward. The ends of the corrugations thus bent form ridges and valleys or furrows in this lateral flange, the ends of the furrows being adapted to reach across the top of the narrow air-chamber and contact with the casing, while the ridges, slightly reced-- ing, leave open spaces between, somewhat V- shaped, which serve as air-openings in the top of said air-chamber. This partition has perforations M M in the space above the ashpit door, thus permitting draft connection between the revoluble damper immediately in front and the interior of the stove. The corrugations in the partition extend vertically, and at the bottom of each alternate ridge of the corrugations a piece about one and one-half inches high and two inches wide is cut out, leaving openings 0 O, that serve the dual purpose of permitting all soot and ashes that may sift in the space between the partition and casing to readily drop through instead of lodging therein andalso alford ing avenues for a part of the heat to be drawn into the space between said partition and casing, said partition and base-casing thereby forming a heating-apartment inside the entire base-casing.

In the rear half of the stove there is a sheetiron diaphragm check-damper P, which is rigidly attached to the sides and rear of the drum and is fitted closely thereto. On either side of the check-damper there are two or more circular openings R R to enable any smoke that may collect under the check-dam per and which may not be drawn forward and over the check-damper to readily pass up into the stove-pipe, which pipe is con'nect'edwith the stove-collar in the top of the drum directly above said check-damper. By means of this check-damper the heat that would largely escape from the stove through the pipe and chimney is checked and spread within the stove, causing the stove to emit a greater heat than it would otherwise give out.

The casing of the stove, including the drum base, top, and bottom, is preferably constructed of sheet-iron and in oval form, the drum having a usual height of about ten inches and the conical base a height of about fourteen inches to secure the largest possible distribution of heat near the floor of the room; but the material, shape, and precise height may be varied without departing from the essential features of my invention.

It will be seen that the chief object of this device is the construction of a stove that will radiate the largest possible amount of heat toward the floor of the building which is in closest proximity, but not beneath the stove. This is accomplished, first, by means of the base of said stove being of inverted conical form; second, by the partition inside of said stove, which is of corresponding inverted conical form with said base and which partition while useful for protecting the sheet-iron in verted conical sides of the stove from being burned out by contact with the fuel also constitutes one side of an inclosure for a heating chamber or compartment, into which a part of the products of combustion is drawn through the openings at the bottom of said partition andthe heat of which products is radiated thence through said inverted conical sides of the stove toward the floor; third, by the check-damper, which by its position in the stove and peculiar construction is adapted tocheck the ascent of the heat into the stovepipe, spread the heat, and drive downward a large part of it into said heating-chamber between said partition and sheet-iron sides of the stove, out of which it will also radiate toward the floor, and, fourth, by the corrugated iron bottom in the stove, the corrugations of which afford dead -air spaces between the sheet-iron casing underneath and said corrugated bottom, such spaces serving as regulators by preventing a too intense heat being radiated directly under the stove.

\Vhat 1 claim as my invention, and desire to secure by-Letters Patent, is-

1. A heating-stove comprising in combination an inverted frusto-conical combustionchamber, a partition or lining within said combustion-chamber and spaced therefrom to form a heating-chamber, said partition having openings at its top adjacent to the wall of the combustion-chamber and openings at its bottom adjacent to the floor of the combustion-chamber, substantially as described.

2. A heating-stove comprising in combination a combustion-chamber, a heating-drum supported thereon and havinga flue connection at one end thereof, a perforated checkdamper spanning the portion of the drum adjacent to the flue connection and secured to the base of the drum, substantially as described.

3. A heating-stove comprising in combination an inverted frusto-conical combustionchamber, a corrugated floor set in the base thereof, said corrugations forming air-spaces between the floor and the casing beneath, substantially as described and for the purpose specified.

4. A heating-stove comprising in combination an inverted conical combustion-chamber, a vertically-corrugated partition having a flanged top and located within said combustion-chamber and spaced therefrom to form a heating-chamber, substantially as described.
