These longitudinal flues terminate in transverse fines 18 18. At the side of the furnace is constructed a suitable stack or chimney 19, and each of the transverse fines is connected to said chimney or stack by a pipe 20. Vithin the chimney or stack 1 provide a sprinkler which consists of an annular pipe 21, having perforations formed upon its inner lower face, as indicated at 252, and this annular pipe communicates with the reservoir 23 by a pipe 2 L. The reservoir is supported by standards 25. and this reservoir is located at a sutiicient height to feed the sprinkler with water or other substance by gravity.

\Ve will assume that the ore is to be treated within the furnace and the metal within said ore to be extracted and refined. The raw material or ore is placed upon the smeltinghearth, and the heat generated by the lire in the fire-box will smelt the ores. The molten mass will then pass into the basin, where it is refined. The slag forming at the top of the refined metal is skimmed off from time to time and the metal drawn from time to time. The dust and other lighter particles arising from the treating of the ore will be collected at the base of the chimney or stack by the sprinkler mounted within the chimney or stack.

In Fig. 3 of the drawings I have illustrated my improved furnace as a single furnace. The same principles of operation hold good in the single as in the double furnace. The features of construction in Fig. 3 are somewhat changed. The basin in this drawing is adjacent to the fire-box, while the smelting-hearth is in the rear of the furnace.

I do not wish to be confined in my claims to a furnace constructed as above described, but also wish my claims to cover a furnace constructed as above described, but placing the basin or basins adjoining the lire-box or lire-boxes and the inclined hearth upon which the ore or other materials are smelted at the farthest end of the furnace from the fire-box or fire-boxesin other words, the furnace as above described reversed in construction in so far as location of the inclined hearth and basin are concerned.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent. is 1. In furnaces of the type described, the combination of a fire-box, an ore-smelting hearth, a collecting-basin, a flue extending in the rear of and beneath said basin and in such juxtaposition thereto, that the products of combustion passing through said flue will communicate their heat to said basin.

2. A furnace comprisinga tire-box, an orcsmelting hearth located adjacent to said tirebox, a collecting-basin constructed below said hearth and having a top, means for removing the products from said basin, and means for conveying the waste products of combustion from said furnace over the top down the rear end and under the bottom of the basin and in direct contact with the top, the rear wall and the bottom of the basin, substantially as described.

3. In a furnace the combination of a furnace structure comprising side and end walls and a central partition, of a central flue located adjacent the furnace and in alinement with the center thereof, a tire-box arranged at each end of the furnace, an inclined smelting-hearth arranged adjacent each fire-box, a basin arranged adjacent each said hearth and a flue extending in the rear of and below each basin, said flues extending below the basins and immediately adjacent thereto andcommunicating with pipes leading to said central flue and the said central flue being provided with a water-sprinkler mounted therein wherein the products of combustion from both fireboxes will be subjected to the action of water from said sprinkler,substantially as described.

In testimony whereof I aiiix my signature in the presence of two witnesses.

JOHN KIRBY.
