SMOKE-PREVENTING FURNACE.
SPECIFICATION forming part of Letters Patent N01 317,522, dated May 12, 1885.
Application lcd January 24, 1885. (No model.)
ject to provide a furnace which shall be sim-` ple in its construction, cheap to manufacture, and effective in its operation.
In furnaces as heretofore constructed the draft has been upward. Coal of all kinds contains a percentage of incombustible material which, in the ordinary furnace, is melted and runs to the grate-bars, at which point it encounters the upward cold air draft and is solidified, forming an impervious mass known as clinkers, 7 which check the draft and make it necessary to clean the grate at frequent i11- tervals, involving labor, loss of time and fuel,
for with the utmost care a percentage of the combustible material is raked out with the clinkers.
My invention consists in the improved construction whereby the above objections are overcome, and in the combinations of parts hereinafter fully described, and pointed out in the claims.
In the drawings, Figure l is a front elevation of a furnace constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal vertical section, and Fig. 4 is a transverse section.
In the accompanying drawings, in which like letters of reference indicate corresponding parts in all the figures, A represents the re pot or bed, which is formed with downwardlyconverging side walls, c b, the side walls b being formed with ledges c for the reception of the grate-bars d. rlhe top of the fire pot or bed is open, as shown, and below the fire-pot is provided a chamber, C, the bottom of which inclines toward the forward or front end of the furnace.
B represents a wall which extends upwardly in an inclined direction from the bottom of the furnace, said partition-wall being angular at its upper end, as shown at D, and
said angular portion D being connected with the front wall of the'furnace. A hole or opening, e, is formed in the partition-wall B at the lower end thereof, and said hole or opening is adapted to be closed by any suitable construction of plug.
It will be seen that by forming the partition-walls B D a chamber, E, is formed, which is closed by a door, E. A passage, G, is formed just below the gratebars and above the chamber E, which passage is closed by a door, H, by opening which entrance may be had to the interior of the furnace for the purpose of re pairing the same.
I represents the iiue leading to the boiler, which flue communicates with the chamber C, said fine being convexe-plano in cross-section and inclining upwardly, as shown.
In starting the lire the fuel is spread evenly over the grate-bars and kindled from the top. It is then left to burn until the bars are covered with glowing embers, when fresh fuel is added to the top. It will thus be seen that as the draft is downward upon the lire the incombustible materials will be melted and run through the grate-bars, and will not solidify, inasmuch as they encounter no cold air, the said incombustible material remaining in a liquid condition until drawn off. It will be obvious that by this arrangement the grate-bars are kept entirely free, so that a free draft is insured, and,further,it obviates the necessity of continually raking the fire to remove clinkers therefrom, thus saving time and fuel.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. The combination, with' the re-p'ot, of the chamber C, the hue I, and the partition B, having an opening and forming a chamber, E, substantially as set forth.
2. The combination, with the fire-pot, of the chamber O, liue 'I, passage G, closed by a door, and the chamber E, having an opening, e, in the inclined wall thereof, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
DAVID DAVIS.
