ELIJAH W. STOUFER, OF SALIDA, COLORADO.

APPARATUS FOR TREATING ORES.

SPECIFICATION forming part of Letters Patent No. 275,729, dated April 10, 1883.

' Application filed October 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, ELIJAH W. STOUFER, of Salida, in the county of Ohafiee, and in the State of Colorado, have invented certain new and useful Improvements in Apparatus for Treating Ores; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, making apart of this specification. V I p This invention relates to certain improvements in smelting, matting, reducing, and concentrating ores; and it has for its objects to provide certain new and improved means for carrying the above-mentioned processes into effect, and in the mechanical construction of the furnace tofacilitate the removal of the metal mass from the furnace should the entire contents of the furnace chill or not be drawn off through the usual openings in the walls of the furnace, as more fully hereinafter specified. These objects I attain by the apparatus illustrated in the accompanying drawings, in which- Figure 1 represents a vertical sectional view of my improved apparatus entire on the line :10 w of Fig. 2; Fig. 2, a vertical sectional view on the line z z of Fig. 1; Fig. 3, a vertical sectional view on the line 3 y of Fig.1; Fig. 4,

a horizontal sectional view, in detail, of the front wall or doors of the furnace, showing a hingejoint connection between the doors and side walls and back of the furnace, to join the sections together and admit of'their separation.

The letter A indicates the main portion of my apparatus, which consists essentially of a vertical water-jacket, or a series of waterchambers, setting upon an inclined waterchamber or bottom, B, and having a removable top, G, consisting of a suitable water-chamher. The saidinclined bottom or water-chamber sets upon an inclined bed of masonry, brick-work, or other support, D, so as to maintain the walls in a vertical position. In practice I prefer to construct the walls, bottom, and top of the said main portion of my apparatus in sections, the vertical portions of which are secured by fastening devices, which may be formed as indicated by the letter E, (shown in Figs. 1 and 5, which represent two plates suitable device.

notched at eto interlock with each other,) or

which may be of any other construction which may prove desirable or convenient. These sections rest upon the inclined bottom, and are confined thereon by means of the vertical flanges F, or by any other approved means. The front sections of the vertical walls constitute doors A A which are hung on hinges G, so that they can be swung back to open the apparatus for the discharge of the contents after the treatment of the ores has been completed, as shown in Figs. 1 and 4 of the drawin gs, wherein double doors A A? are made with inclined or angular abutting or overlapping ends, in which construction the door A must first be opened. The door may be made removable and secured in place by interlocking plates, as shown in Fig. 5, or by any other The doors do not extend quite to the front edge of the floor, leaving a space, H, through which the reduced metal may run out. Near the lower part of the said main part of my apparatus, at the front and rear, it is provided with tuyeres I, through which a blast of air may be introduced at a proper time. The respective water-chambers forming the water-chambers or water-jacket are provided withinduction and eduction ports K and L, by means of which a circulation of water may be kept up through the said water. chambers or jacket.

The letter M indicates a chamber detachably located at the top of the main portion of the apparatus, which is provided with vertical tubes N, extending from the interior of the main portion of the apparatus. up to within a short distance of the top of the said chamber M, through which the products of combustion pass 0E from the interior of the part A, of the apparatus. From the chamber M exten d pipes O to a chamber, P, entering the same below a perforated partition, B, through which ashower of water may be distributed. The saidcham-- her at its bottom is provided with an outlet,- S, through which the water and condensed products of the volatilized ores may be drawn on. The said chamber is provided with an escapeflue, T, through which the final products of combustion escape. The said chamber M is supported upon trestles U, or in any other convenient manner.

In operation the main portion of the apparatus is packed with successive layers of fuel and ores, the same being inserted by removing the top section and charging in the material. The combustion is then urged by a blast of air introduced through the tuyeres. The products of combustion, with the volatilized portions of the ores, pass up into the chamber at the top of the main portion of the apparatus, where they permeate the steam generated therein, and the volatilized metallic portions are partially condensed and collected. The products then pass to the final condenser, where the metallicportions are thoroughly condensed by the water, the smoke passing off through the eduction-tiue. The material left in the portion A of the apparatus when the operation is complete is removed by opening the doors and raking orotherwise removingit from the inclined bottom. The bottom,being formed of a water-jacket casing, will withstand great heat without being burned, and, as the bottom of the furnace is inclined from the rear to the front and door of the furnace, may be entirely removed,and a solid mass of metal may be readily removed from the furnace by wedging or prying upon the sides and back walls to force the block down the inclined floor and through the open front. This is often a diflicultand expensive operation in the usual form of furnace when the entire mass of metal cools or chills before the reduction of the metal is completed, and necessitates the tearing away of the permanent walls of the furnace. The sides, bottoms, and tops of the furnace being rectangular and made in separate water-jacketed sections, the entire apparatus may be conveniently packed or loaded for transportation, and the entire structure may be quickly taken apart for repairs or for removing a solid mass of metal from the interior of the furnace. By making the chamber, as herein described, to be readily removable, the sedimentary matter precipitated by the condensation of the products of combustion may be readily removed from the chamber and the interior thereof easily cleansed.

oftubes, N, ample exit-area isprovided, with an increased area around each tube to allow ample space for condensing the products of combustion. As the chamber P is separated completely from the furnace, and connected to the condensing-chamber M by pipes O, the products of combustion are first expanded in chamber M, and, passing through the contracted pipes O, are again expanded in the enlarged chamber P by the jets or drops of watercoming through the apertures in the partition P. The floor of the chamber P being in vclined from its ends to the middle, the matter precipitated may readily be removed through As the con- (lensing-chamber M is provided with a number the discharge-outlet S, and the chamber may be readily cleansed.

I do not broadly claim a furnace with an inclined bottom, as such floors have been heretofore employed in calcining and others kilns, the contents of the furnace being removed through small or contracted openings in the front wall of the furnace. Neither do I broadly claim a furnace for reducing metals provided with chambers for condensing the products of combustion from the furnace by means of steam or water chambers and baths.

The letter V indicates inspection-openings by which the operation may be watched.

The tuyeres in practice I prefer to provide with openings at the top or other portion, and suitable conduits by means of which chemicals may be introduced with the blast to act in conjunction with the ores in the treatment of the same.

Having thusdcscribed my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In an apparatus for treating ores, the main portion, consisting ofa water-jacket constructed as described, and provided with an inclined water-chambered bottom and removable water-chambered top, and doors hinged to the side walls of the furnace or made in a removable section in order to displace the entire front of the furnace, substantially as and for the purpose described.

2. The combination, with the main portion of the apparatus, of the removable steam-generating chamber located at the top and adapted to rest within and against its vertical walls, and provided with flues extending to near its top and leading into the steam-space of said chamber, and communicating with the main chamber, through which the products of combustion and volatilization pass, substantially as and for the purposes specified.

3. The combination, with the main portion of the apparatus and the chamber connected therewith, of the final condensing-chamber ar- ELIJAH WILLSON STOUFER.
