COAL-STOVE.

Specification forming part of Letters Fatent No. 49,33 3, dated `August B, 1865.

To all whom 'it may concern panying drawings, which make a part ot' this specification.

Like letters represent and referto like or corresponding parts.

Figure lis a vertical section ot' my improved base-burning coal-stove from side to side at right angles with the exit-pipe, and showing the coal-supply reservoir or chamber surrounded with an air-chamber, and also showing the tire pot or chamber containing an annular chamber, and immediately below the said supply-reservoir and its chamber the outer or radiating chamber, the fire-grate, the 'ash-pit, and the iue or tlues in the base of the said stove, and each morefully hereinafter described and set forth. Fig. 2 is a vertical section of lthe said stoves containing the said improvements and on a line from front to rear through the exit-pipe. Fig. 3 is a horizontal section on the dotted line A A and B B of Figs. l and 2. Fig. 4 is a horizontal section on the dotted line C C and D D of Figs. l and 2. Fig. 5 is a horizontal section on the dotted line E E and F F of Figs. l and 2.

The nature of my said invention and improvements consistsin the employment of a self-seeding or coal-supply reservoir or chamber, which shallbesurrounded by an air-heating chamber of any convenient shape or capacity, and into which cold air shall enter from 4the room where the said stove may be used through a supply-tube constructed for that purpose at or near the bottom of said annular air-heatin g chamber, by means of which the air enters said chambers and there becomes heated through, and by means oi'an outer casing, which casing in part forms said annular chamber,

' and rising therein it escapes into the room to be warmed or heated through openings at the top of such air-heating chamber constructed for that purpose; or it may be made toV enter the radiating chamber through and by means of a valve or damper at or near the top of the said chamber, and thence be thrown down and upon the fire or ignited coal to aid combustion, in the manner substantially as herein described and-set forth. l

Italso consists in the employment of aiirepot constructed with `an annular air-chamber, formed between an inner and outer plate `or casing, into which air is admitted through an opening in front and in rear of the stove, in the manner substantially as herein "described and set forth.

To enable others skilled in the art to which my invention relates to make `and use the same, I will here proceed to describe thereonstrnction and operation thereof, which is as follow, to-wit: l

I construct the base and outer cylinder of my improved stove in `any convenient and-substan tial manner. The {ire-pot A is made either of cast-iron or lire-brick, as may be deemed best; but I generally prefereast-iron lined with tire-brick up to within a short distance of the perforations through which atmospheric air is admitted to the re in the :fire-pot, as shown at a, Figs. 1 and 2.

There is an air-chamber entirely surrounding the fire-pot, as shown `at l, Figs..1 and 2. This annular chamber maybe of any capacity desired, and there maybe-as many-openings or perforations communicating with `thetirechamber as may be deemed best, through which atmospheric air passes into the said fire-chamber to aid combustion in the consumption of the gases and smoke, or as much thereof as may by such means be burned or consumed. Cold air is admitted into said air-chamber through the openings or dampers B `and-B in the front and rear ofthe stove, and passes Vup through said airch amber and through the said perforations, thereby burning the gases, smoke, and othery combustible material i arising `from `the surface of the fuel inthe fire-pot, asaforesaid, and also preventing in a great measure the too rapid burning out of the inner part of said re-pot if constructed of cast-iron only,

and it' of lire-brick the same result is reached 'relative to such brick. l The said self-feeding reservoir or chamber I construct of cast-iron or other suitable material, and of any size or strength deemed best, and may extend down to near the top of the said fire-pot, if deemed best so to do. G, Fig. 2, is opening or damper in the back part of the stove, through which v2 and 5, ator near the top ofsaid ann/ular chamber D, may then be opened, so that such air .so heated shall be thrown into the radiatingchamber I, Figs. 1, 2, and 4, and thence down the same into or upon the-fire or burning inaterial in the vsaid lire pot or chamber A, andv thereby aid combustion. Thevheat arisin-g from the fuel in the combustion-chamber or fire-pot Ipasses up and surrounds the said air-heating chamber D surrounding the said coal-supplyreservoir chamber, and thence into the iiues in the ba-se of the stove through theopeniugs GG,

Figs. l and 3, and thence in the line of the draft at the bottom of the vertical exit-pipe J, Fig. 2.

-When the damper Kin the back connectingpipe, L, is closed the draft is turned down Ward and passes down the outer side ofthe fire-pot or combustion-chamber into the chamber in the base of the stove, and thence into the back pipe through the openin g M, Fig. 2, as aforesaid.

To use my said improved stove, a fire is built in it in the usual manner ou the grate N, Figs.

i 2and 3. The coal is then put in the said feeding chamber or reservoir .E through an openingin the top thereof, which is then closed. The draft is admitted to the combustion-chamber and to the ire therein through the grate N, in the usualmanner, by means of a sliding damper, which is in the door that closes or opens into the ash pan or chamber, which is situated below the iregrate, and which receives the ashes from the fire-grate when the stoveis in operation. By opening the pipe-damper K the direct draft is had, which, when closed, sets into operation the circuitous draft, as aforesaid described. All dampers must be closed in order to, stop all draft when desired. By the means hereinbefore described l am enabled to construct a stove containing a great amount of heating and radiating surface, which is very desirable in parlor and like stoves 5 and by the aid of my said self-feedin g chamber or coal-supply reservoir will be obviated the necessity of too frequent filling the stoye with coal. The said feeding-chamber being once filled with coal will last from thirty to sixty hours, feeding the re iu the combustion-chamber as fast as it is required by the burning or consumption ofthe coal within the same.

It will be seen that admit atmospheric air into the said chamber surrounding the said coalsupply reservoir at or near the bottom of the said chamber, and, by means of and through a tube passing therefrom through the radiatingchamber and through the outer cylinder or casing which surrounds and forms the space between it and the casing which forms the said ar-heatin g chamber around the said coal feeding or supply reservoir, into the room Where such stove is used. Such air, entering the said heating chamber in the manner aforesaid, arises in and entirely Iills the said heatingchamber with fresh air, and, heating the same to a desirable temperature, it is thrown into the room to be warmed, while at the same time it contributes largely to preserve the immediate lower end of such coal-supply chamber or v reservoir, and also protects and preserves the said casing by which the'said air-heatin g chamber is formed, as aforesaid, from undue wear or destruction by or from the heat in and arising from the fire-pot or chamber of combustion below, as aforesaid.

By placing a tin or sheet-iron tube upon the top of my said stove of a size sufficient to cover the said openings in t`1.e top of the said air heating-chamber, and continuing the same to the room in the next story above that Where the said stove is used, such room or story may be thus warmed.

Having thus described the construction and operation of my said invention, what I claim, and desire to secure by Letters Patent of the United States of America, is-.

l. The employment of the said self-feeding reservoir or chamber, E, surrounded by the air-heating chamber D, with cold-air-supply tube Oi, arranged and combinedwith a baseburningcoal-stove,in themanner substantially as and for the purpose herein described and set forth.

2. The employment of a fire-pot or combustion-chamber constructed with an annular hotair chamber, with openings B B, arranged in the manner substantially as herein described and set forth.

3. The combination of the damper H with the openings or dampers o o in the coal-supply reservoir or chamber and said air-heating annular chamber D, in the manner substantially as and for the purpose herein described and set forth.

In testimony Whereofl have, on'this 1st day of May, A.-D.'1865, hereunto set my hand.
