ANODE-MOLD.
Specification of Letters Patnt.
Patented Nov. 30, 1909.
T 0 all whom ?It may concern:
Be it known that I, JoI'N F. MILLER, a citizen of the United States, resii'ling at Trail, British Columbia, Canada, have invented certain new and useful Improvements in Anodc-Molds, of which the following is a specification` reference being had to the drawing accompanyng and fornnng part of the same. I
M invention relates to molds for casting anodes for use in the electrolytic refining of impu-e meta is, for example lead. and has for its object to provide a nold iu which anodes of uniferm size may be cast and readily removed without dismenbering the mold.
i .show the interier and the format-ion of the gular form, but are slightly narrower at' joint between the two side pieces at the edges thereof. Fig. 2 is a central transverse section of the mold. Fig. 3 is a view partly in plan and partly in lmrizo'tal section. Fig. 4 is a detail sectional View on line TV-IV, Fig. 1. Fig. 5 is a perspective View of the wedge or device used for drawing the casting from the mold.
The mold consists of three parts,-two side members, 1, 2, and the drawing wedge 3. v The side members are of a general rectantheir bases, to facilitate withdrawal of the casting, or anode, as will be readily understood. At the top, each member is provided with lateral extensions or wings 4:, so that the anode cast in the mold will be formed with wings or extensions by which it may he supported in the tank containing the electrolyte.
Near one edge of the inner face of the side member 1 is a bead or rib 5, and near the opposite edge of the same side member is a similar bead or rib 6, while across the bottom of the member is a similar bead or rib 7. Between the ribs and edges are bolt holes, to receive bolts 8, which extend through corresponding holes in the other side member.
The side members are assembled as shown in Figs. l, 2 and'3, withthe rib on one hearing against the inner face of the other. In Fig. l the rib at the right edge or side of the mold is shown in section. Around the members, between the ribs and the bolt holes, is placed a strip of soft rubber or other suitable packing, 9. lVhen. the bolts are tightened this packin is compressed, as' will be readily understoo making a liquidtight joint between the members or plates.
At the top of each side member or plate are two lugs, 10, preferably beveled on their outer faces 11, as shown, to engage correspondingly beveled faces of lugs 12 forned at the ends of the drawing wedge or member 3, shown more clearly in Fig. 5. This member is of wedge or trapezoidal form, as shown, and fits closely the space between the side plates, as shown in Fig. 2. On the inclined edges of the drawing member are shoulders 14, so that the molten metal in the mold will positively engage and take a firm hold on said member. The lugs 12 are so located on the drawing member that the distance between their inner faces is but slightly greater than 'the distance between the outer faces 11 of the lugs 10, while the latter lugs are equidistant from the center line of the mold, so that when the drawing member is inserted into the mold it will be accurately positioned at the center of the top thei-cof, as will be readily understood. The said drawing member is preferably of such depth as to extend slightly below the bottoms of the lateral extensions 4.
The mold members l, 2, 3, are preferably of soft, tough, gray cast-iron, free from all injurious cold-shuts or blow-holes. The inner surfaces of the side members l, 2, are perfectly plane and are made as smooth as possible. If the mold is to be'used as hereinafter described, the inner surfaces of the plates l, 2, when themolten metal comes in contact therewith, must be absolutely free from pits or projections of any kind. In order to permit ready access of the dressing or planing tools to all parts of the inner surface of the member l the bottom rib may be cut away at its ends and the openings thus made are after-ward filled by small blocks 15. The preferred way of using the mold is as follows: The mold, with the drawing member in place, is supported Vertically in a suitable cooling medium, such as water, which is circulated around the mold, the latter extending a short distance above the Water, say, about two inches. Molten lead or other metal for the anode is then deposited in the mold, fiowing up around and lirmly embeddig the drawing member 3. When the nolten niet-al is solidified and sufiiciently cooled, power is applied to the drawing member, as by means of an eye, l(', seeurely fastened thereto, and the casting is drawn out, after which the drawing nenber can be removed laterally from the casting and reinserted in the noid for the next molding operation.
From the foregoing it will be seen that the mold is simple and eomparatively inexpensive, and that the anodes are ali of the same size and shape. V
The mold may of course be made in other forms than that shown and may be modified in various ways without departure from its proper scopo as defined by the appended claims.
What I claim is:
1. A mold for casting anodes, eomprising in combination, a pair of spaced side members or plates, and a drawing member posi tioned in the top of the mold and provided With means for positive engagement with the nolten metal in the mold, whereby when the metal is soiidified the castin can be drawn out of the mold by means o the said drzuving member, as set forth.
2. A mold for casting anodes, comprising in combination, a pair of side members or plates separated by a rib extending around the sides and botton of the mold and spaced from the edges thereof, a strip of yielding material outside of the rib, and a series of rr clamping devices engagng the side plates or members outside of the said rib and binding the plates firmly together, as set for-th.
3. A mold for casting anodes, comprising in eombination, a mold having an open top, and a drawing member supported in the top oi' the moid and provided with shoulders on its ends to be engaged by the molten metal, whereby when.the metal is solidified the casting can be drawn out of the mold by means of the said drawing member, as set forth.
4. A mold for casting anodes, conprising in combination, a mold having an open top and having spaced lugs on its top, and a drawing member extending into the open top of the meld and eonstrueted so as to be positively engaged by the molten metal therein and provided with lugs adapted to engage the lugs on the top of the mold to aceuratelv position the said drawing member, as set torth.
