HEATING STOVES.

TO ALL'WHOM'IT MAY CONCERN:

Be it known that I, WILLIAM A. BARLOW, of Elkhorn, in the county of Walworth, and State of Wisconsin, have invented an Improved Stove, which is specially applicable to burning bituminous coal, peat, 8m; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification Figure 1 being a top view of 'the stove, the cover or top plate being removed.

Figure 2, a central vertical section thereof in a plane indicated by the line :0 :0, fig. 1.

Figure 3, a horizontal section of the same in a plane indicated by the line as :v, fig. 1.-

Like letters designate corresponding parts in all of the figures,

Let'A represent the body of the stove. In the upper part thereof I insert two concentric, or nearly concentric cylinders, so as to form an outer annular chamber, 13, a central chamber, 0, and an intermediate annular chamber, G; and inside of the interior'chamber C I place a downwardly projecting flue or pipe, D, substantially as shown. The outer chamber B is closed at the top, but at the bottom it is open, so as to communicate with the fire chamber below and the draught first circulates upward therein. from the upper part of the chamber B, through flue openings or-pipes, a a, into the upper part of the chamber O, which is closed both at the top and bottom. The draught-then, after plunging down nearly to the bottom of the said interior chamber, finally'ascends through the pipe D to the smoke pipe E. The plunging movement of the draught in the chamber C causes the greater part of the soot and particles of unconsumed fuel to be deposited on the bottom, II, of the said chamber. This bottom is made to tilt, when desired, as indicated by red lines in fig. 2, or otherwise to open, so as to discharge the' soot collected thereon down into the fire chamber to be at once consumed. The bottom H is then righted or closed again, and the operation of the stove goes on as before. The bottom is operated by a rod, m, extending up through the top of the stove, or by any other suitable means. This construction is peculiarly effectual in depositing the soot and products of imperfect combustion from the draught and preventing their escape into the chimney to foul it afid the atmosphere above it, so that thereby bituminous coal may be burned with cleanliness. The intermediate annular chamber Gr, although not necessary to the device above set forth, is very useful as an addition thereto, in obtaining much'heat from the stove which otherwise might be wasted in the draught. It also protects the partition plate or plates, between the chambers 13 and C, from burning out, by keeping comparatively cool air in contact with them. Air from the outside is admitted freely into this chamber G, through one or more pipes or passages 17 6, across the annular chamber B; and the upper end of this air chamber opens into the space under the cover I, which has perforations or. openingsff, by which the air escapes into the room after circulating through and becoming heated by The products of combustion then pass the walls of the chamber. The pipes or passages a a, which form the communication between the chambers B and (3,, cross this 'air chamber and assist in heating the air therein. In connection with the inverted chamber B and the closed interior chamber C, I introduce air in small streams through apertures d d, under the bottom H of the said chamber 0, against which the products arising from the burning fuel first impinge. Thus fresh airis supplied so as to complete the combustion quite perfectly and deposit considerable ofthe soot before the draught proceeds further upward. As represented regularly in. the drawings, these apertures d 01 open from the air chamber G, whence the air is drawn for supplying the combustion. But I contemplate a modified-construction here, which may be preferable. -.An annular space or passage g, separated from the chamber G by a partitiomp, (or applicable in place, if the chamber is not used,) is supplied from passages it formed through the chamber B. These passages are conveniently constructed by adding are or segmental plates Z l, under the pipes b b, so as to enclose crescent-shaped spaces between them. These additional plates also serve to, protect the pipes b b from destruction by the intense heat, and may beirernovable when requiring to be replaced. The partitions between the chambersB and C may be more or less conical, or otherwise vary from the cylindrical form represented. Stoves with the improvements specified above may have descending flues from the top to the base, and an ascending fine or fines from the base, without interfering with the operations or materially departing from the construction above described. I

I do not claim an interior fine or smoke pipe, with a tilting bottom or damper, as I am aware that such have before been used; but what I claim as my invention, and desire to secure by Letters Patent,

The interior chamber (L provided with a tilting or otherwise'opening bottom H, and a downwardly project-t ing pipe or flue D, substantially as and forthe purpose herein specified.

I also claim the combination of the chamber C, constructed and arranged as above specified, and chamber B, substantially as and for thepurposeherein set forth. 1 I

I also claim the combination of the air-circulating chamber G with the chambers B and G, constructed and arranged as above specified, substantially as and for the purpose herein specified.

Ialso claim the air-supplying openings or passages d d, at the base of the chamber 0, constructed and arranged as above specified, substantially as and for the purpose herein; set forth. v
