Specification forming part of Letters Patent No. 163,442, dated May 18, 1575; reissue No. 6,845, dated January 11,

' and useful Improvements in Stoves; and I do hereby 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 my invention relates to make and use it, reference being had to the accompanying drawings, which form a part of this specilif cation.

My'invention relates to an improvement in stoves designed for heatingrapartlnents, and is so fully described in the following description and claims that no preliminary recital is needed.

In the drawings, Figure l is a longitudinal vertical section ot' a stove 'embodying my invention. Fig. 2 is a detached View, showing in plan section the opening CV at the base ot the exit-flue.

A is the fire-pot; B, the combustionchamber; C, the exit-flue, leading to the smoke-due. D is the smoke-line. It: may or may not be provided with divisions'D D, whereby the products of combustion may be made to descend, circulate about Ythe ash-pit, and ascend into the smoke-flue D, which, however, forms no part of my invention. .E is the fuel-reservoir. forations, or slots, e. F is an air-space left between the perforated wall of the reservoir and the outer wall G of the drum-section ot' the stove.- H is a register for admitting external air. 1 is a flue leading from the air-chamber F into the smoke-flue D. t' is a damper. f is a diminished oriice through which the gases that may collect in the chamber F are discharged into the combustion-chamber B.

The operation of the device is as follows: Fuel contained in the fuelreservoir E will, when the stove is well heated, emitgases in the process of coking the fuel in the magazine. These gases will escape into the room, and become not only obnoxious, but will be wasted, unless means are provided for their escape or consumption. This desideratum is accomplished by the provision of the perforations It is provided with per.

e, made through the magazine, whereby the draft, as shown by the arrows in the drawing, is directed from the air-space F into the magazine E, whence it passes down through the fuel,.assisting in coking the same before it reaches the lire-pot A. The openings or oriices f at the bottom of the air-chamber F are not intended at all to facilitate the draft, the only practical function of the openingsf being to permit the escape ot' dirt or the like that might collect in the chamber F. v

lt has been found by practical test that the draft and entire functions of the stove are not at all a'ected by the openings f, but continue the same whether the said openings are provided or not.

To assist the draft from without to within the magazine A, and at the same time to furnish more oxygen, a register, H, is provided,

whereby the external air can be thus admitted and employed.

When it is desired to diminish the heat of the stove, and for that purpose quell the combustion in the combustion-chamber B, the damper i in the due I is opened, and the gas in the chamber permitted to escape directly into the smoke-flue D, instead of being made to pass down through the fuel in the magazine, as would otherwise be the case.

It will be noticed that the outer wall G of the drum-section of the stove forms the outer.

wall ot' the air-chamber F, and this outer wall or drum is dropped down into the combustionchamber, so as, by its continuation, to diminish the air-space F at its base, and form the contracted opening f for the escape of ashes, dirt, and the like from the airspace, as heretofore mentioned.

I am not aware that a stove provided with such a perforated reservoir and air-space F has ever before been provided with a fine, I, and with or without a damper, t', and I am not aware that a stove of this description has-ever before been made with a fuel-reservoir, and a smoke-flue, D, leading therefrom, the opening O into said flue extending below the base of the said fuel-reservoir, whereby the smokeiiue within the limits ot' the stove is made to form a portion of the combustion-chamber.

It should be observed that the register VH is y so located with respect to the perforated reservoir that gases escaping through the perforations will rise into the space above the register H, and when theregister H is opened, the draft passing in through it will catch up-this escaped gas, and, mixing with it,'will pass it down through the fuel in the reservoir, and inally into the eombustioncharnber in a Asufticiently oxygenized consideration to be consumed therein before reaching the escape-flue.

It should be observed, further, that the ob ject of this invention is to coke the coal in the magazine. so that it shall be delivered into the combustion chamber in the form of coke; .and the construction of the stove is such, as

' will readily be seen, that all the gasesthat escape from the magazine in the process of coking will be oxygenized and burned, and consequently utilized in the combustion-chan1 ber; and the object 'and function ot" the airspace around the fuel-reservoir is to effect this coking ofthe coal and combustion of the gases, and not, as vhas heretofore been practiced, to keep the fuel cool and thus prevent coking, so as to deliver the coal inits natural condition into the reservoir.

It should be observed, finally, that the ilue I and damper t' serve the following purposes, among others: If the mica doors are dropped down, or, in other words, opened, the gases concentrated from the magazine in the upper part of the stove would escape into the apartment. So, also, if the top Aof'the stove should be opened, alike result would ensue; but by opening the damper t' at such time, the gases, instead of escaping into the room, would pass into the smoke-flue.

What I claim isy Y Y 1. In a magazine-stove, the combination with the converging walls of the air-space, the same forming at their lower extremity the annular space f, of the opening C, constructed to extend above and below the lower portion of said converging walls, substantially as and for the purpose set forth. p

' 2. The combination with the perforated reservoir E, the perforations of which communicate directly with the air-space, and the air-space F, of the Aflue I and damper i, substantially as and for the purpose described.

3. The combination ,with the perforated reservoir E, the perforations of which connect directly with the air-space F, of air-space F, flue I and'airregister H, substantiallyas and for the purpose described.

4. The 'combination withV the combustionchamber B and perforated reservoir E, the pert'orations of which communicate directly with the air-space F, of the exit-Hue C and lue I, substantially as and for the purpose described.

5. The combination with the combustionchamber B, airspace F, and dues C and I, of

the air-register H, by which means the draft has direct transit through the reservoir E,

withoutvpassing down by an .indirect course,

substantially as and for the purposedescribed.

v6. The combination with the annular airspace, and theVfuel-reservoir, having perforated wall, of the flue I leadingto the smoke yflue D, substantially as and for the purpose set forth. v

In f testimony whereof I. have lsigned my name to. this specification in the presence of two subscribing witnesses.
