UNITED sTATEs PATENT oEEToE.
DAVID WELLS, OF LOWELL, MASSACHUSETTS.
STOVE.
Specification of Letters Patent No. 22,392, dated December 21, 1858.
To all whom it may concern:
Be it known that I, DAVID WELLS, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Smoke-Consuming Stoves, Furnaces, Sac.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a transverse vertical and central section of a stove with my improvement applied to it. Fig. 2, is a longitudinal vertical section of ditto, taken in the line Fig. l. Fig. 3, is a horizontal section of ditto, taken in the line y, y, Fig. l.
Several letters of reference indicate corresponding parts in the several ligures.
This invention consists in a peculiar arrangement of flues, an air-heating chamber and smoke chamber substantially as hereinafter fully shown and described, whereby the combustible portion of the products of combustion is brought in contact with a suitable portion of heated atmospheric air and ignited in a chamber separate from the fire chamber, but by the heat or fire therefrom.
The object of the invention is to obtain all the advantages derived from the consuming of the combustible portion of the products of combustion without detracting from the eliicacy of the lire chamber itself as a source of heat, by admitting directly upon or over the lire atmospheric air in order to consume the inflammable portion of the escaping gases.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, represents the body of a stove which may be of rectangular or any suitable form and B, is the lire chamber at the lower part of the stove.
C, is the ash pit below the grate D, of the fire chamber.
D, D, are two flues, placed one at each side of the stove at its back part. These flues extend down a certain distance and communicate with a chamber E, which at its upper part extends the whole width of the stove and extends down to the bottom of the stove and communicates with the smoke pipe F. Between the chamber E, and the back plate a, of the stove there is a chamber Gr, which communicates with the external air by means of passages b, b, which extend down through the chamber E, one at each side see dotted lines in Figs. 2 and 3. The chamber G, communicates with the chamber E, by means of perforations a, and the chamber E, communicates with the fire chamber B, by means of perforations b.
The operation is as follows IVhen the fire is kindled in B, the smoke and products of combustion will pass upward in the body A, of the stove and then down the flues D, into the chamber E. Cold air passes up through the passages b, b, into the chamber G, and becomes heated. This heated air passes through the perforations a, see blue arrows, and mixes with the products of combustion in the chamber E, and a small quantity of llame from the tire chamber B, will pass through the perforations Z), into the chamber E, and ignite the inflammable product in E, which consequently is a supplemental heating chamber. It will be understood that the draft upward in the body A, of the stove and down the flues D, is sufficiently strong to carry with it all the smoke and inflammable gases, a small portion of llame only, will pass through the perforations o, just sutlicient to ignite the products of combustion in E, as soon as it mixes with heated atmospheric air. By this arrangement it will be seen that the lire in the chamber B, will not be cooled or deadened by the admission of the external air directly upon it, and that the supplemental smoke consuming device is an auxiliary affair and can not detract in any way from the eli'iciency of the lire chamber B.
I am aware that various plans have been devised for admitting heated air into stoves and furnaces, so that the products of combustion may be mixed therewith in order to insure the burning of the same. I therefore do not claim broadly such idea, but
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-
The arrangement of the flues D, D, smoke chamber E, air heating chamber Gr, and lire chamber B, the latter communicating with the smoke chamber by means of perforations b, and the smoke chamber communicating with the air heating chamber by perforations a, substantially as and for the purpose set forth.
DAVID WELLS.
