FURNACE FOR TREATING THE ORES "OF MERCURY.

SPECIFICATION forming part of Letters Patent No. 256,677, dated April 18, 1882.

Application filed July 23,1881. (No model.)

To all whom it may concern:

Be it known that we, EDWARD Gr. HALL, of Healdsburg, in the county of Sonoma and. State of California, and MYRON D. HASKINS, of Guerneville, in the county of Sonoma and State oi'G-alifornia, haveinvented a new and Improved Furnace for Treating the Ores of Mercury, of which the following is a specification.

Figure 1 is a vertical section of our improved furnace. Fig. 2 is a vertical section on line a; :r in Fig. 1. Fig. 3 isa plan view. Fig. 4 is a horizontal section on lineyyin Fig. 2. Figs. 5,6, and 7 are detail views of the cam-shaft and cam.

Similar letters of reference indicate corresponding parts.

Our invention relates to improvements in furnaces for treating the ores of mercury; and it consists in a novel conslruction' and arrangement of parts, as hereinafter described, and pointed out in the claims.

. Referring to the drawings, A is the outer wall of the-furnace, within which is formeda tireplace, B, having an arched top, 0.

Above the top of the fire-place B there are two similar chambers,'D, having inclined floors a and arched tops I). Passages L lead from these chambers to the condensers.

Above the chambers D there is a cylindrical chamber, E, having a funnel-shaped bottom, 0, from which achute, d, leads to the pipes c, which communicate with the chambers D. In

the chute at there is a valve,], and the pipes A vertical shaft, F, is'journaled centrally in the chamber E, and is slotted to receive splines in the boss or hubs of the cams G, said hubs being divided so that they may be readilybolted together on the shaft. An arm is placed in each space between the diaphragms.

' A flue, H, surrounds the chambers D, and communicates with an annular space or flue, I, that surrounds the chamber E. A number of passages, j, lead from the fire-place B to the flue H for leading away the products of combustion,and auxiliary furnaces J are arranged in the space between the contracted portion of the chamber E and the annular wall L, which projects from the upper surface of the chambers D and surrounds the contracted part of the chamber E, for imparting heat to the said chamber in addition to that received from the fire-place B through the flue H. The chamber E is stayed by a number of fire-bricks, 7c, placed in the annular space I. These bricks also serve the purpose of equalizing and distributing the ascending heat generated in the fire-places.

Chutes K, having suitable stop-valves, extend from the lower portion of the floor of the chambers D through the wall A for discharg ing the depleted ore. i

The manner of using our improved furnace is as follows: The chamber E is filled with ore and lime in the usual way and the cams Gare rotated. As soon as the ore becomes partly roasted itis discharged into one of the chambers D by opening the valve fand one of the valves 9. In its fall it becomes separated and broken up, so that the mercury is easily liberated when subjected to heat in the chamber D, and is driven ofi' and conveyed through the passage 1) lo-the condensing-chamber. The chambers D are each made sufficiently large to contain two full charges from the chamber E. By means of this arrangement the ore can be subjected to an intense heat in the chambers D for several hours longer than the charge he chamber E, having a funnel-shaped bottom arranged above the said chambers, and provided with the diaphragms h, projecting from opposite sides of the chamber nearly across the same, and the revolving arms G, and communicating with the said chamber at its bottom, substantially as and for the purpose set forth. V

2. In a furnace for treating ores of mercury, the combination, with the chamber E, having a-funnel-shaped bottom and the fire-place B, of the chambers D, having inclined floors, and communicating with the said chamber, and arranged between the said chamberand fire-place, substantially as and for the purpose set; forth.

3. In a furnace for treating ores of mercury,

the combination, with the chambers D, the annular wall L, and the chamber E; having its lower part contracted, of the furnaces J, arranged in the space formed by the said annular wall and the lower contracted part of the chamber, substantially as and for the purpose described.

4. The annular space I, surrounding the chamber E, and connected with the flues H and furnaces J, as and for the purpose herein shown and described.
