IMPRovEMENTlN sTovEs FOR HEATING WATER.

Specification forming part of Letters Patent No. 129,922, dated July 30, r1872.

To all whom 'lt may concern:

Be it known that I, EDWARD BWURNE, of Pittsburg, in the countyoi` Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Stoves designed for Heating Water and for other purposes.

The nature of my invention will be readily understood by the following description, taken in connectionwith the accompanyingdrawing, wherein- Figure 1 represents a perspective view of 'my improvedstove; Fig. 2, a transverse vertical section of the same.

To construct :my stove I make a large metallic tank, A, capable of holding fifty or sixty gallons of water, and of such a shape as to embrace the iire on its sides and reach around its back. This tank I form of a single piece of metal by casting it entire, by which it is made cheaper, more durable, and less liable to get out of order than when constructed of several pieces. -It is then adjusted upon abutments within a shallow cast-iron box or bed-frame, B, of similar shape, and so arranged with rela- `tion thereto as to leave a space, C, between the bottom of the tank and the interior of its supporting-frame, and also a like space, D, completely around that portion of the tank immediately in the rear of the fire-place, which fire-place E is fitted with a grate of the open ordinary kind, but closed at the top at a little distance from the tank. Behind the tire is introduced a thick verticalplate, P, so perforated or piercedwith numerous holes as to give free escape to the products of combustion through -them in that direction. A plain or ornamental casing, F, of cast-iron is placed over the tank and fire-box, the upper horizontal plate H of which is arranged sufficiently high above the top o'f the tank to afford a broad shallow space between the two; this is divided by a vertical wall, f, having therein an opening, g, leading directly into the chimney k, which opening is provided with a Vslidimng door or damper, R, that may be operated by means of a rod, N, extending to the outside. The upper plate or tablet H of the stove has alarge central opening therein, covered by a conical polygonal cap, T, constructed with a central divisionwall, W, the lower edge of which meets and rests upon the upper edge of the perforated plate P at the back of the fire, while it extends upward so nearly to the inside apex of the cone as to leave but a narrow passage, e,

at that point, through which a portion of the' heat and escaping products of combustion are compelled to pass on their way to the chimney, and by so passing increase the heat of the cone. This conical cap T is constructed and applied to the stove for the purpose of and intended to facilitate the heating of sad or ilat irons, which may be arranged point upward around it, with their faces reclining against its numerous sides, and their bases resting withinthe encompassing-ring J, by which they are kept from sliding away; or, if circumstances require it, the cone may be removed and supplemented by a simple flat plate having therein one Vor more kettle-holes, such as are foundin ordinary cooking-stoves. The front of this stove, directly above the grate, is provided with an inclined chute, L, through which all the fuel that supplies the fire is introduced; vand for the purpose of preventing the escape of smoke in that direction said chute is furnished with a tightly-ttin g door, S, so hinged thereto as to be easily opened or closed. The tank is also provided with an inlet-pipe, a, situate at one end near the top, and an outlet-pipe, b, at the' same end near the bottom, by which a continuous supply and circulation of water may be kept up.

T he several parts of this stove being con structed, combined, and arranged as shown, it will be seen that on opening thedamperR the tendency of the heat to ascend, together with the smoke and other products of combustion, will cause them to pass partly through the opening ein the apex of the cone and para ly through the holes in the disvision-plate P, after which they traverse the top of the tank A on their way to the chimney, and thus escape into the atmosphere. By closing this damper the currents -of heat, smoke, &c., will, on reaching the rearof the division-wallP, flow downward, and after circulating under the tank eventually pass up its back onward to the chimney, thus, to a very considerable ex tent, increasing itsheating-surface.

Claims.

I claim 1. A stove and water-heater so constructed with a perforated divisionwall, P, at the back of the re as to form a ue, D, between it and the tank A, by which the heat and products of combustion maybe made topass down under and around the tank on their Way to the chimney, in the manner shown, for the purposes set forth.

2. I claim a stove and Water-heater so constructed and combined With a conical polygonal cap, T, provided with a central divisionwall, W, and opening e, as that a portion of the heat and accompanying products of cornbustion may be made to traverse, in an up-anddown direction, the inside of' said conical cap, on their way to the chimney.
