APPARATUS FOR ELEGTRUDEPOSITING,4 No. 526,482. Patented Sept. 25, 1894.
UNITED `STATES PATENT OFFICE..
HENRY L. ERIDGMAN, E BLUE ISLAND, ILLINOIS.
l APPARATUS FOR `ELECTRODEPOSITING SPECIFICATION forming part of Letters Patent No. 526,482, dated September 25, 1894. l
Application filed October 3, 1393.
` tus, of which the following is a specification.
The object of my invention is to provide `such a serial arrangement of the cathodemolds of angular shape in the electrolytic bath as to cause an enhanced stirring effect f on the electrolyte by rotation of the cathodes therein.
In the accompanying drawings-Figure l 1s a view in longitudinal sectional elevation showing an electro-depositing apparatus provided with my improvement. Fig. 2 is a section taken at the line 2 on Fig. l and viewed in the direction of the arrow. Fig. 3 shows one of the anodes in front elevation. Fig. 4 is a perspective view of a cathode of the an gular form employed in the apparatus as represented in Figs. land 2.
A is the depositing vat containing the electrolytic liuid, (the line of which is indicated at 06,) andhaving journaled in it the rotary shaft B, surrounded by insulation r and which is connected with one pole' of a generator C.
The anodes D may be of the plate-shape illustrated and supported to be suspended in the vat at suitable intervals apart, on the `upper edges thereof, as shown, with one side of `each bearing against a conductort connected with the opposite pole of the generator and extending along an upper edge of the vat;.and the anode-plates are slotted, as at c,
` to adapt them to straddle the insulated roedge.
tened in place each by means of aclip o, of
metal, engaging the plate at a recess q in its Serial No. 487,111. (No model.)
central'opening g and secured to the shaft B by means of screws o' penetrating the insu- ""lation r to contact with the metal of the shaft and thereby include the cathodes in the circuit of the generator C.
The shaft carrying the cathodes is slowly rotated inthe electrolytic bath, and the deposit takes place on` the exposed surfaces of the plates E. After the deposit on each cathode has accumulated to the desired thickness, the resultant rectangular slabs or plates E' (four in number on each plate, according `to the illustrated arrangement of the insulation upon it)fmolded, as it were, by the deposit on the cathode-surfaces, are taken off, or stripped therefrom, thus Without incurring, by the act of separation, impairment ofthe desired plate-form of the molded metal article, one of which is represented in Fig. 4 as undergoing separation from the mold. The cathode plate-molds E may then be prepared for another deposit, the preparation consistingvin coating the surfaces for the deposit with a substance, such as graphite, which will prevent too great adherence of the deposit to the cathode.
A particular advantage is attainedby the comparatively numerous cathodes of the angular plate form applied at intervals to the rotary shaft, namely, that of causing thorough stirring of the electrolytic duid by the rotation of the shaft. I produce the greatest stirring eect, and, moreover, also a relative balancing effect of the angular plates E on the shaft, by disposing them, as indicated in Fig. 2, successively, at varying angles to each other, thusto cause the corners to extend successively in different planes radially with relation to the longitudinal axis of theshaft..
What I claim as new, and-desire to secure by Letters Patent, is-
1. In an electro-depositing apparatus having a depositing vat, a rotatably supported shaft, one or more anodes and cathodes in the form of angular metal plates, supported on the shaft to rotate with it and to alternate with the anodes `and extending at their corners, successively in different planes, substantially as and for the purpose set forth.
2. In an electro-depositing apparatus having a depositing vat, a rotatably supported IOO shaft and anodes suspended in the vat atinvided with v.insulating stripsn their sides tervalsalong theshaft, and cathodes in the and dividing them into molds, substantially form of angular metal plates supported ou as and for the purpose set forth.
