COMBINED ROASTING AND SMELTING FURNACE.
SPECIFICATION forming part of Letters Patent No. 286,822, dated October 16, 1883.
Application filed July 16, 1883. (No model.)
To aZZ whom it may concern Be-it known that I, EZEKIEL HOLMAN, of Sandy, in the county of Salt Lake and Territory of Utah, *have invented a new and useful Improvement in Roasting and Smelting Furnaces, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specification.
This invention relates to combined roasting and smelting furnaces forthe reduction of silver, lead, and other ores; and the invention consists of the novel construction hereinafter described and claimed.
In the drawings, Figure l is a side elevation I of my improved roasting and smelting furnace.
Fig. 2 is a longitudinal section of the same; and Fig. 3 is a cross-section on line 00 w of Fig. 1, enlarged.
A indicates the fire-chamber, B the firegrate, andO the ash-pit, of the furnace. From the bridge-wall D, at the rear of the fire-chamber, extends a flue, E, which inclines slightly upward from the fire-chamber and terminates at the base of the chimney F, withwhich it communicates. The chimney and flue are provided with a continuous partition, which is supported on parallel vertical walls H in the bottom of the flue, forming an inclined floor or hearth, G, and a series of under lines, I, in order that the hot air shall completely envelop the ores as they are fed down the hearth G from the feed-door J at the base of the chimney. The inclined hearth leads to the smelting-cavity K, in which the melted ore is collected.
L M are holes leading to the well, for extracting the metal and slag.
N indicates a series of small doors in the sides of the inclined flue E, through which the progress of the ore to the bottom or smelting cavity may be noticed and aided when necessary.
K is the lead-well, partly broken away, and K K are weighted doors, and K isaplatform by which the doors N are reached. 7
In the upper part of the furnace-walls is located a superheater, O,which is to be supplied with steam by the pipe P, and which in turn supplies steam to the superheater Q, at the top of the'fire-chamber, by means of the pipe I R. superheated steam is to be jetted into the fire-chamber from the superheater Q, through an opening, S. Through the roof of the furnace enters a blast-pipe, T, which is adapted to direct the blast in such manner as to keep the roof from being burned out by the heat from the fire-chamber, and which forces the hot air directly on the ore,where it falls to the bottom of the line E from the hearth G.
Vith the above construction coke and other high' priced fuels may be dispensed with, as ordinary coal can be used with good results;
.WVhat I claim is 1. The'combined roasting and smelting furnace having the inclined hot-air flue E, pro vided with the roasting-hearth G, under flues I, and side doors, N, and the smelting-cavity K, substantially as shown and described.
2. The combination of the inclined hot' air flue E, having the inclined hearth Gandsmelting-cavity K, the fire-chamber A, the super- EZEKIEL HOLMAN. W'itnesses:
