GAS-STOV E.

fiPECIPICATION forming part of Letters Patent No. 326,089, dated September 15, 1885.

Application filed December 5, 1884.

To all whom/it may concern:

Be it known that I, JOHN W. BAKER, a citizen of the United States, residing in the city of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to gas'stoves for producing both light and heat, in which fiuetubes to carry off the products of combustion are employed as radiating-tubes to impart heat to the surrounding atmosphere, my present invention being an improvement upon the apparatus for which a patent has been allowed to me upon an application filed April 28, 1884, Serial No. 129,493; and it consists of a series of such tubes. connected at each end with an annular drum or hollow ring, the present construction differing from the former in the combination and relative arrangement of the radiating flue-tubes, drums, and central flue, whereby the products of combustion are directedupward through the series of radiating flue-tubes, instead of downward, and also in the combination of these parts so arranged with afunnel draft-flue, whereby a current of hot air will be induced to the gas-jets sufficient in volume to enable the hot-air chamber used to produce such current to be dispensed with, and arranged around an inclosed gas-burning device, from which the products of combustion of the ignited gas and air are wholly directed into such flue-tubes, and carried off to the chimney by a pipe connecting the same with the upper drum or hollow ring.

In the drawings, Figure 1 is a plan view of the gas-stove; and Fig. 2, a vertical section through the center, showing the relative arrangement of the several parts.

Upon a suitable stand or supporting-frame (indicated at A) is supported an annular drum or hollow ring, B, from which arise a series of upright flue-tubes, D D, connecting at top with a second annular drum or hollow ring, 0,150 which is connected adraft-pipe, G, leading to the chimney.

Within the lower drum, B, is supported a cylindrical casing, forming an air-chamber, H, and within the latter is held and supported a gas-chamber, L, and within the latter, again,

(No model. 1

a second cylindrical casing, forming a central flue, F, with two or more flue-tubes, E E, extending therefrom and passing through the gas-chamber L, the air chamber H, and into the lower drum, B, forming thereby a direct airtight connection wit-h the central flue, F.

Gas-tubes J are secured to the top of the gaschamber L, and are arranged vertically around the flue-chamberF, extending to about the top thereof. 7 v I o Gas is supplied by the tube K at the base of the stove.

In order to utilize the light produced by the '6 ignited gas and air, and also prevent drafts from affectingthe flame, and to induce at current of hot air direct-tothe gasjets, 1 place a chimney, M, preferably, of the form of an inverted frustum of a cone, resting on the upper rim of the casing H or other support provided therefor, and extending down to below the top of the flue-chamber F and said gastubes, and the top of-said chimney M extending upward to the drum 0. The chimney may be made 'of bright metal, and so serve in u this form not only the purposes stated, but act as a powerful reflector in throwing the light upward and into the room, and will also of itself cause an upward draft of fresh air so from below to the ignited gas at the top of said chamber F, which air will be heated, as well as the gas in the tubes, by the heat within the outer casing, H, or, if the latter be dispensed with, as may be done, then from the 8 heat radiated from the hot flue-tubes D D.

The operation is as follows: Gas enters the chamber L, and is ignited at the ends of the gas-tubes J, where the heat produced thereby will induce an upward current of air through 0 the open bottom of the chamber H, and will be heated by contact with surrounding hot surit faces, as will also the gas in the gas-tubes; and the products of combustion from such ignition of gas and air will be drawn downward through the flue F by the chimney-draft, passing in its passage thereto through the tubes E, drum B, radiating-tubesD, and upper drum, 0, these several flue-passages presenting extensive radiating-surfaces, wherebj the surrounding atmosphere will beheated, my apparatus serving the double purpose of giving both light and heat.

I do not claim, broadly, in this application the combination, with a central flue, through which the products of combustion pass downward, of a series of upright radiating fluetubes located betweeuan upper and a lower annular drum, nor the combination of such parts when arranged to direct the heated products of combustion first to the upper drum, and thence through the radiating flue tubes in a downward direction therein to the lower drum, as this constitutes the subject of my former application for patent hereinbefore referred to; my present invention consisting in a different combination of these parts, whereby the products of combustion pass first to thelower drum, and thence upward through the series of radiating flue-tubes in a contrary direct-ion to the passage of the same through the central flue, and also in such combination of these parts with an upper draft-flue, whereby a current of hot air is induced to the region of the gas-jets without the use of any directing air chamber surrounding the central flue.

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

1. A gas-stove consisting of the combina tion, with a lower annular drum or hollow ring, B, of a like upper drum or ring, 0, and a series of upright radiating flue-tubes, D D, placed between them, and connecting said drums with each other, a central flue chamber, F, supported within said series of upright flue-tubes and between said drums, and connecting air-tight at its base with said lower drum, a gas-chamber, L, and a series of gastubes, J J surrounding-said central flue, the said parts being constructed and arranged substantially as described, in order that the products of combustion of theignited gas will be drawn into and down through said central fluechamber to the lower drum, and from thence upward through said series of flue-tubes and upper drum to the chimney, and impart heat by radiation to the surrounding atmosphere.

2. The combination of the upper and lower annular drums, O and B, with a series of connecting upright fines placed between them, and a central fluechamber connected at its base with the lower drum, B, and located within said series of flue-tubes and between said drums, agas-chamber and a series of gastubes surrounding said central flue and eX- tending nearly to the top thereof, and a chimney, M, supported within said upper annular drum, 0, and extending down to said gas-jets, the said parts being constructed and arranged substantially as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature this 26th day of November, A. D. 1884.
