TO ALL WHOM IT MAYVCONCERN:

Be it known that I, ROBERT B. THOMPSON, oi' the city of New York, county and State of New-York, have invented a new and useful Improvement in Base-Burning Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing formingpart of this specification., in which drawing- Figure 1 is a vertical section in the -plane of the line as :r of ig. 2; I

Figure 2 is a vertical section in the plane of the line y y, g. l.

Figure 3 is a detailed inverted view of the ring F and supply-pipes H.

This invention relates to stoves of the-class commonly called base-burning. At the lower part of the reservoir, which contains` the supply of fresh fuel, is an annular air-chamber, which receives air by means ofpipes that go through the luefspaces at the base of 'the stove, and which discharges such'air into or upon the incandescent fuel through perforations in the bottom of said annular chamber, such chamber having also at its bottom a series of I'ngers,'arrauged between the perforations,-aud projecting downwards towards the ire-pot.

The letter A designates the outer shell of the stove. Itsform and its ornaments can be varied to suit the Y taste and judgment of the maker. Its sides, opposite to or justabove the level of the top ot' the fire-pot, have openings, which are provided with plates 'of mica or other suitable transparent material, B B, dto. The fire-pot 'C and ash-pit D are arranged as shown in the drawing, said fire-pot being made more or less flaring, as maybe preferred by the maker. Above the fire-pot, but disconnected therefrom, is the fuel-reservoir, E, arranged within the shell A, and rising up to c r nearly up to its top, in such a` manner as to be beneath the cover K, which closes the opening in the topoi' the stove. The fuel is introduced into the reservoir through the said opening. From the mouth of the said opening a flange, O, extends downwards, as shown inthe drawing, which ange enters the top of vthe cylinder or reservoir E, and by that means holds it in place, and also forms a guide Afor the fuel, so that no fuel can fall between the reservoir E and shell A.

The top'rot` the reservoir E has several openings, L, at suitable distances apart, which are formed by cut tingjts upper edge or top down at lthose places, the objectv being to establish or allow free communication between the interior of the reservoir and th interior of the outer shell AI The lower part of reservoir'E is surroundedby an annular chamber, F, from whose lower side extend lingers, I, which form a vertical grate, reachi ing nearly to the level of the top ofthe fire-pot, butnot connected to the {ire-pot. The lower side of said annu* lar chamber, furthermore, is perforated with air-holes, G, which, n'this example, are placed between the ngers I, in alternation therewith, as is shown in iig. 3. .The annular chamber is supplied with air by means of air-pipes H I-I, which start from below the bottom 'of the stove, and are taken through the flue-spaces J J', in its base, and thence upwards through the flue-space that surrounds the firepot, above which said fire-pot they are curved, so as to approach and enter said chamberat opposite sides. '.lhe area of said pipes is made large enough to furnish a sufficient supply of air to secure the combustion of gases that come 0d' from the fuel While it is burn ing. rlhe annular chamber F forms an integral part of the reservoir E, and the pipes H H, where they enter said chamber F, are firmlyand strongly attached thereto, one object of such construction being to enable me to 'support the reservoir wholly upon said pipes whose upper parts are arched to form supports bf suicient strength for this purpose. 'lhe said air-pipes arcmainly supported upon hollow brackets Q Q, which extend from the upper edge of the {ire-pot, as shown in iig. 1, upon which brackets rest flanges P P, that are formed around the pipes, the said flanges boing properly fastened to the brackets by bolts or otherwise, to prevent disa placement. 'lhose portions of the pipes which are below the brackets Q Q are partly suspended therefrom, and are partly supported by the bottom of the stove, through which they pass.

This arrangement greatly simplifies and improves the construction of stoves of tliis'class, the reservoir and its appurtenances being easily got at for repair, and being easily removed by removing the top of the shell at thejoint It, er at a lower joint, and then removing the bolts or pins which attach the flanges P P to the brackets Q Q of the fire-pot.

rIhe base of the stove is occupied by the ash-pit D and the base-lines J J, into and through whichiall the products of combustion pass on their way to the exit-opening N, which is`formed on the top of the flue-chamber J at the back ofthe stove. The baSe-nes J J discharge theproducts of combustion into the said chamber J', in Whose rear wall is a draught-regulating damper, M.

It will be observed that this stove has a large radiating-sur such as will effectually secure a large heating-surface near the floor o air which is discharged into the stove from the air-chamber E is heated by passi which traverse the whole height of the base-lines J'J.

Having thus described my invention, what I claim as new,

1.- Supporting the reservoir E upon brackets Q Q, in com set forth.

2. The combination of the annular air-chamber F around the tical lhars or fingers I, substantially as shawn.

3. The combination of the annular airllchamber F, formed around the lower part pipes H H,`wl1en the latter extend downwards through the base-lines J J, substantially as shown.
