IMPROVEMENT IN APPARATUS FOR CONDENSING QUICKSILVER.

Specification forming part of Letters Patent No.

`153,479, dated July 2s, 1874; application tied I May 20, 1874.

To all whom 'it may concern .Beit known that we, FERDINAND FIEDLER and J AMES B. BANDOL, of New Almaden, Santa Cla-ra county, State of California, have invented an Improved Quicksilver-Goudenser5 and we do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use our said invention or improvement without further invention or experiment.

Our invention relates to an improved ta-nk or vessel for condensing the fumes of quicksilver after they have been taken from the retorts or furnace in which they are produced. Our improvement consists in constructing the condensing-tank of wood and glass, as hereinafter described.

Referring to the accompanying drawings forming a part of this specification, Figure l is a perspective View of o ur furnace. Fig. 2 is a side sectional elevation. Fig. 3 is a view of a sash. Fig. et is a horizontal section. Fig. 5 is a view showing the manner of securing the transverse partitions.

A represents a tank or vessel in the form of a parallelogram, but any desired outside form or size will answer. This tank or vessel we construct of wood, leaving numerous openings in its sides and ends, which are covered with windows, or panes, or plates of glass set in a frame. WVe prefer to construct an elongated box-shaped tank, as this form is the most convenient, and presents a better window surface; but our invention can be carried out in a tank of almost any shape. The openings B, all ex cept those in immediate contact with the floor of the condenser, are constructed in the following manner: A frame, L, is constructed ot' a size large enough to receive the window-sash or plates of glass. The four outside edges of this frame are grooved, as at O, to receive the planks which form the siding of the 'condenser, thus strengthening the condenser, and preventing the planks from warping. The upper rail of said frame has one or more openings, 1', leading from the groove to the inside ofthe condenser, thus providing a roadway for the quicksilver which condenses on the inner side ot' the tank, and which will naturally follow down the wall and drop through said openl ings to the floor of thetank. The inner edges of this frame have on their upper and side edges a flange, against which the windo w-sash, or plate, or pane of glass rests, and into the upper edge of the lower sill of the frame a groove, S, is cut, in which the window-sash sits. This groove has one or more openings, t', similar and for the same purpose as the openings c' above described. A crossbar, T, which is secured on one side of the frame by an open mortise, and on the opposite side by a similar mortise, with the side ot' the frame beveled to make said bar slide easily, fastens the window-sash in its place or any other suitable fastening can be used.

The frames which rest on the lioor ot' the condenser are constructed in the same manner as those already described, with the exception that the lower rail or sill of the frame is lett out, and the window-sash rests directly on the floor of the condenser. The lower edge of the through which the quicksilver condensed in the tank makes its exit into a suitable gutter, which conducts it to the receiving-tank. The floor of the tank is built on an incline, having its apex in the center of the saine, and sloping to both sides an inclination which should not be less than two (2) inches to the foot. The tank is provided with interior wooden partitions D D, which a-re so arranged as to provide alternate openings or passages above and below, in the ordinary manner of arranging the partitions ot' a condenser. The outside edges ofthe partitions and end sidings of the tank are fitted into upright grooved timbers V, and it' tongue and grooved boards are used for forming the partitions and ends ot' the tank, the rails which fasten them together are driven into the tongue of each plank and covered by the groove of the next or succeeding plank. The sides of the condensing-tank are fastened to the outer edge of the grooved timbers V, and the whole is bound together by stron g scantling W',placed vertically against the different divisions or partitions outside otl the tank, and secured by metallic rods or bolt-s e and nuts j'. The bolts or rods pass transversely across the tank from side to side through each partition, and are protected from the action ofthe fumes by a grooved timber, through sash is perforated with two or more openings,

which they pass, and which is covered again by the plank of the partition. The rods which secure'the corner timbers pass along the ontside of the ends of the tank. F is the inletpassage at one end, and through which the fumes enter the tank; and G, the outlet-passage at the opposite end, through which they may pass to another tank, or to the other condensing apparatus.

le have discovered that condensation of the mercurial fumes is accelerated Where they Having thus described our invention, what We claim, and desire to secure by Letters Patent, is

l. A Wooden condensingtank, A, provided with windows, panes, or plates of glass B B, substantially as and for the purpose described.

2. The combination ofthe Windows, having perforated sash, with the frames of the condensing-chamber, as and for the purpose set forth.

3. In the condensing-tank A, the bolts or rods e, which bind the walls together, concealed by passing them through in grooved timber, which again is covered by the partitions D D, for the purpose specified.

In Witness Whereoi` We hereunto set ourhands and seals.
