i Application led October 3, 1906. vSerial No.7337305.

positive terminals used in the preci itation of precious metals from cya-nid or li 'ze solutions.' y

An object sought to be attained is the prevention of the formation of impurities in the electrolyte asis the case Where metallic anode is used.

It is further desired to provide an anode that Will have a longer period of usefulness than those at present in use.

A further object is to provide an anode of this cla-ss wherein the metallic terminal Will be so situated that it will not be attacked by the electrolyte. i

In'the partially broken away perspective accompanying and forming art of'this specication, reference numeral() 1 designates a sac-k of canvas or other suitable material having vertical lines of sewing 2, extending to Within a. short distance of the top, thus dividing the sack into a number of vertical pockets connected at their tops to a horizontal transverse pocket.' The por ire ts are packed tightly with a metallic oxid, preferably peroxid of lead in a granular form. A conducting Wire is placed in thcl horizontal pocket and the granular filling is. pressed tightly in contact therewith by strips of wood -5 placed on each side of thc pocket and clamped together b v means of bolts (j. T he ends of strips 5 may be allowed to project beyond the sides of the bag 1 and rest on sup ports laced over the tank where the anode 1s use( Yertical strips 7 may he fastened to one Or both sides of the bag l to prevent it i sagging out of shape and' coming directly in contact with the cathode.

In the o eration of this invention, any number of t e anodes with their corresponding cathodes being suspended in'an electrolyte, ,current is caused to iiow into Wire 3, whence it asses into the granular filling and through t e electrolyte to the cathode, de-

positing the metals from the solution thereon. -In orderto prevent the electrolyte acting upon the Wire 3, the anode is submerged on y to a point a short distance below the level of the wire;l

I claim:

l. An anode comprising a metallic oxid and a support lor the same formed ot' vege- Y table fibers.

2. An anode comprising peroXid of lead in a granular form and a support for the same 'formed of vegetable fibers.

3. An anode comprising a non-conducting envelop divided into .a number of vertical pockets, a transverse pocket connecting .them at the top and a metallic oXid inclosed in said pockets.

4. An anode comprising a non-conductinlr envelop divided into a number 'of vertica pockets with a transverse pocket connecting them at thev top, a metallic oxid inolosed in said pockets and a Wire said transverse pocket.

5. An anode comprising a non-conducting envelop divided into a number .of vertica pockets, a transverse pocket having a Wire therein, a metallicv oxid inclosed in said pockets and means for compressing the contents ol said pocket around said wire.

In testimony whereof I-"have signed my name to-this specification in the presence of two subscribing Witnesses at'Virginia City,

in the State of Nevada, this 11th day of September, A. I). 1906.
