UNITED STATES PATENT Fries- CHARLES J. BEST, OF DENVER, COLORADO.
FURNACE AND DEVICE FOR TREATING ORE.
SPECIFICATION forming part of Letters Patent No. 674,595, dated May 21, 1901.
Application filed March 2, 1901.
T aJ/Z whom it may concern:
Be it known that I, CHARLES J. BEST, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of 0010- rado, have invented a certain new and useful Improvement in Furnaces and Devices for Treating Ores, of which the following is a specification.
My invention relates to ore-treating furnaces and is illustrated in the accompanying drawings, whereiu- Figure 1 is a perspective, with parts broken away, of the furnace. Fig. 2 is a side elevation. Fig. 3 is a front view. Fig. 4 is a detail. Fig. 5 is avertical section through Fig. 1.
Like parts are indicated by the same letter in all the figures.
A is the front wall of the furnace; B B, the fuel-doors; C, the grate-bars on which the fuel is thrown; D D, the ash-doors; E, the fire-wall in the rear of the fire-box; F F, arches thrown, respectively, over the fire-box and the heating-chamber in the rear of the fire-wall.
G G are doors'opening into the upper part ofthe roasting-chamber. H H are lower doors 7 leading therefrom through which the tailings are removed.
J is a flue leading from the furnace into the smoke-stack K.
L is the rear wall of the furnace.
M is a collecting-chamber connected with the roasting-chamber by the pipe N and having within any suitable cooling or condensing coil supplied by the pipes O O. P is an escape-flue from this condenser M.
R R are suitable tile-pieces, which may be overlapped, as indicated in Fig. 4:.
S S are projections on the top of the arches which receive the tile-pieces, but leave openings between them so there is a free circulation for the hot gases around and upon all sides of said arches and under the tile.
It is obvious that this device will be used in substantially the following manner: The furnace will be fed through the doors B B, so as to generate a high degree of heat, prefer- Serial No. 49,550. (No model.)
ably about 1,200 to 1,500 Fahrenheit, in the roasting chamber above the arches. The products of combustion pass out through the smoke-stack K. The roasted ores are removed from the rear wall L through discharge-doors in thesame. These ores so treated and roasted are then to be run through various inachines and treated by the various processes which may be desirable or necessary for extracting the precious metals therefrom. As these several processes and operations are no part of the'present invention, I will n0t.fur-
ther describe them or any of them.
I claim- 1. A furnace for roasting ores, consisting of a fire-box, a series of arches above the same and separated from each other, a heating chamber in the rear of the fire-box, a series of arches above the same and separated so as of a fire-box, a series of arches above the same and separated from, each other, a heatingchamber in the rear of the fire-box, a series of arches above the same and separated so as to make flue-spaces between such arches from the fire-box to the heating-chamber, a suitable flooring above said arches, and transverse openings across the arches from flue to fine beneath the flooring.
