sTovE AND HEATER.

SPECIFICATION forming part of Letters Patent No. 297,772, dated April 29, 1884.

Application tiled July 29, 1831. Renewed October 25, 1883. (No model.)

To a/ZZ wiz/m, twenty concern:

Be it known that I, THOMAS MARA FELL, a citizen of the United States, residing at the city of Brooklyn, county of Kings, and State 'of New York, have invented new and Improved Attachments for Stoves and Heaters, of which the following is a specification. My invention relates to the manner of fitting the nre-places of stoves, heaters, open and closed grates, or other furnaces which are used for heating dwellings, 825e.; and the object of my improvementsor attachments is to obtain a more perfect combustion of fuel.

A further obj ect of .my improvements or attachments is the consumption of smoke and the utilization of the valuable gases now lost, and'which I attain by my attachments or mechanism,which are constructed and arranged in.

such manner as to supply such gases with 2o highly-heated air and in .finely-divided streams,

a great portion'of such heat being extracted.

from the gases escaping bythe chimney or outlet. r

Figure 1 is a vertical section,and Fig. 2 a plan through at the line l 2, of my improvements or attachments as applied to a house stove or heater; and Fig. 3, a vertical section, and Figs. 4 and 5 plans through at the lines 3 4 and 5 6, respectively, of my improvement as applied to a cylinder or similar stove. Fig. 6 is an enlarged View in cross-section taken on a horizontal line above the fuel and through the exit smoke-flue. Y

Similar letters refer to similar parts throughout the several views.

The stove, heater, or grate is divided into two chambers, A and B, by a peculiarly-constructed nre-proof pendent partition placed centrally in Figs. 3 and 4, but nearer to the 4o front in Figs. 1 and 2, and stretching across the width of the fire-place. In this partition and opening near the bottomthereof are a number of small passages or hollow heating spaces or chambers, C, receiving air at the top from a metal heating and distributing chamberfD, having lips into which said partition is cemented, and corresponding openings on the lower side thereof. E represents a number of air-tubes screwed or fastened into the top of 5o the chamber D and passing to a sliding airregulating plate, F. Gry is a -fuel-door; H, a damper; I, the ordinary shaking-grate bars;

K, ash-pit door; L, back plate; M, the repot lining; N, an outernue-chamber; O, the chimney; and I is a horizontal partition-plate provided with a damper, H, which rests partly on the top of the hollow pendent partition eX- tending verticallyacross the furnace,dividing it into a distilling-chamber and a combustionchamber. -By this arrangement (the ash-pit 6o door being provided with the usual air-regulator) air can be admitted in suitable quant-ities, either above or below the fuel, and as no air is admitted by way of the `fuel-chamber B or through the back plate, L, such chamber is merely distillatory in its function-that is, passes a highly-carbonized gas intothe coinbustionchamber A. For a perfect combustion of this gas it is very necessary that it be thoroughly oxygenized, to effect which it is 7o .important not only to evenly mix a proportion of oxygen, lbut such admiXture must be at a high temperature before a proper combination can be obtained. To this end, therefore, I allow but a small proportion of air to pass through by way of the grate-bars, but permit the larger quantity of air to enter by' way of the regulator F, air-tubes E, heatingchamber. D,and the air-ducts or heating-spaces O. -The combustion brought about in the front 8o chamber, A, develops alarge amount of heat, alarge portion of which passes upward against the face of the perforated partition, around the heating and distributing chamber D, through and around the air-tubes E, into the outer 8 5 chamber, N, and eXit by the chimney or due O.

It will be seen that a very large proportion of waste heat goes to heat the inflowing cold air, and, further, that by the introduction of the chamber D the direct inflow or current is 9o broken up and evenly supplied to the main heating-chambers contained in the partition.

-The object of the damper H is to permit a direct outflow of gases when a re is first lighted; but such opening should be closed at all other times.

The partition-plate P in Figs. 3 and 4 eX- tends horizontally across, as is shown, and in this way a cylinder or round stove is divided into two chambers, for the purposes as before 1o explained.

Now, what I claim is l. As an improvement in stoves and heaters, the combination of the hollow pendent partition dividingthefire-place into two cham- 3. In stoves or heaters, the heating and di- 2o bers, one of them being a combustion-chamber and the other a distilling-chamber, said partition having outer air communications, and an air-heating chamber, the partition also having perforations at its bottom,which adapts it to supply highly-heated air in fine streams at or near the surface of the fuel, substantially inthe manner shown and described.

2. The combination, in stoves and heaters, of the pendent hollow and perforated partition, said partition having an air-heating chamber and outer air communications, and adapted to supply highly-heated air in iinc streams at or near the surface of the fuel, plate L, grate-bars I, distilling-chamber B, and combustion-chamber A, all arranged for lioint operation substantially as herein shown and described, and for the purpose set forth.

vidin g chamber D,f1tted with the pipes E, passing across the exit-line, and receiving a supply of cold air from without, in combination with the hollow pendent partition delivering the heated air downward at or near the surface of the fuel, for the purposes and in the manner substantially as described.

4. In stoves orheaters,an air-regulator opening into pipes E, and a heating-chamber, D, connecting with a hollow pendent partition,

lin combination with grate'bars I, damper H,

and back plate, L, all in the manner substantially as described.
