IMPROVEMENT IN BASE-BURNING STOVES.

The Schedulereferrefi to in these Letters Patent and snaking part of the same.

To all whom itmay concern.-

Be it known that I, STEPHEN SPOOR, of Phelps, in the county of Ontario and State of New York, have invented Improvements in Base-Burning Heating- Stoves; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawing making part of this specification- Figure 1 being a central vertical section of a basebnrning heating-stove, provided with my improvements.

Figure 2, a view of the bottom thereof.

Figure 3, a horizontal section of the same in aplane indicated by the line 20 w, 'fig. 1, lookingdownward.

Figure 4, a horizontal section, in a plane indicated by' the line a: x, fig. 1, looking downward.

Figure 5, a horizontal section in a plane indicated by the line y y, fig. 1, looking'upward. v

Figure 6, a horizontal section in a plane indicated by the line .1 fig. 1, looking upward.

' Figure 7, a front view of .a part detached.

Figure 8, a front elevation of the stove.

Like letters designate correspoudingparts in all of the figures.

Let A represent the magazine or reservoir;

B, the combustion-chamber;

.G, the fire-pot; and

D, the ash-chamber of a base-burning heating-stove.

Around the lower part of the magazine A, andimmediately over the combustion-chamber B, is a division-plate, E, covering the entire diameter'ot' the stove at that height, and provided with a set of holes, a a, for admitting boilers and other cooking-utensils, as in a cooking-stove. These boiler or cooking-holes are located at regular intervals around the magazine, and open upward respectively into spaces G G, which are separated one from another by vertical radial partitions 7) b, and are inclosed by removable covers 0 c, as shown, or by doors arranged in any suitable manner.

1 These covers or doors conform with the outer contourof the stove, and together, when in place, form the outer case of that part of the stove, entirely inclcsing and concealing all of the cooking arrangements inside, so as to remove every appearance thereof. But when in the act of cooking one or more of the covers may be removed, as required.

The spaces G G may serve as well for small ovens as for mere cooking recesses. But the rear space H is constructed and arranged especially for an oven, to bepfovided with shelves or grates (l 11, like ordinary cooking-stove ovens. Beneath this oven there is no boiler-hole; but there is under it a flue, f, and at its sides, by the adjacent partitions b b, there are vertical fines g g, which convey the products of combustion upward into an annular space, 7:, reaching around the magazine A, above the cooking-spaces and ovens G G and H, from which annular space the draught has its; exit into the smoke-pipe at '5. Thus the oven H has at all'times a continual circulation of heat around it sufficient to make it effective for baking whenever there is any considerable activity of combustion going on in the stove.

The passageof the draught from the combustionchamber B into the fines f, and g g is either direct or indirect-direct through a valve-aperture, 1, intothe flue f, and through apertures m indirectly into the side fines g g, all these apertures being through the plate E; and indirectly, first downward into an annular space, 12-, around the fire-pot O and ash-chamber I), and thence into the lower end of a flue, 0, at the back. side of the stove, and upward therein into the flue f, through an aperture, 12, in the plateE.

The apertures m m might be; dispensed with. The draught may be allowed to pass out directly through the valve-apertures l m m when desirable, as when kindling a-fire in the stove, or when it is not desired to use the full heating power of the stove. At other times the draught may pass down through the annular space a in the base of the stove, thereby conveying and rajdiating the heatclose down to the floor, and increasing the radiating surface.

Theexit' of the draught by either way is determined and regulated by a sliding valve or damper, q, which is shoved in to close the apertures lm 1n and open the aperture p, as shown by heavy dotted lines in fig. 5 and is drawn out to open the apertures Zm m and close the aperture 12, as shown bylight dotted lines in the same figure and seen in fig. 1.

The spaces or recesses G G and H are separated from theannular flue-space it above them by a horizontal plate, I, which hasperforations through it, as shown at ar, figs. 1 and 3, to be opened or closed by a register or. valve-plate, K, with corresponding holes therein. The objcct'of these holes and valve is to carry off any smoke or steam from the cooking recesses or ovens into the draught-space, and toclcar the latter of accumulating soot or ashes.

The valve-plate K may beanoved and regulated by means of a handle, s, fig. 1, projecting down into one of the'recesses G G.

The magazine A may be enlarged above the said recesses, as shown, so as to give it as much capacity as possible, and yet make it small as desired within the recesses.

The fire-pot O is provided with an'annular grate, L, at the bottom, with a central open space in the same, covered by a close cone, M, as shown. with this cone I introduce the draught air, to support the, combustion of the coal, into the ash-chamber D, through a pipe or close passage, t, the inner end of In connection which extends centrally, or nearly so, up into the 1101- low of the cone, as shown in fig. 1. The air is thus caused to impinge against the lower surface of the cone, to prevent its becoming too hot and burning away, and also to heat the draught for improving the combustion of the coal.

The admission of the air into the pipe t is regulated by a valve, 11, under the bottom of the stove, as represented in figs. l and 2.

The cone M may be supported by the pipe t, by means of connecting arms a: v, figs. l and 6. The grate L vibrates around the cone.

The partition-plates I) 1), between the recesses G G, serve to support firmly the upper part of the stove, and, together with the covers or doors 0 0,- give a proper external form to that part of the stove, as well as inelose, divide, and conceal the cooking recesses or ovens.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The separate, inclosed recesses G G H, situated around the magazine A of a base-burning heatingstove, in combination with a plate, E, situated beneath said recesses and over the combustion-chamber B, and provided with cooking-holes a a, substantially as and for the purpose herein specified.

2. The radial partition-plates b b, separating the recesses or ovens G G H, and the inclos'ing covers -01 doors a c, in combination with the said cooking recesses or ovens, substantially as and for the purposes herein setforth.

3. The arrangement and combination of the valveapertures l m m, leading directly to the fines f g g, and the annnlar.diving space in, pipe orfiue 0, and valve aperture 1), leading indirectly to the said fines, in combination with a regulating damper, q, substantially as and for the purpose herein specified.

4. The perforated plate I'and valve K, arranged between the recesses G G and flue-space h, substantially as and for the purpose herein set forth.

STEPHEN SPOOR.
