ROBERT J WISNOM,OF VIRGINIA CITY, NEVADA AN ODE.

Specification of Letters Patent.

' Patented Nov. 1'7 1908.

Application filed May 7, 1907. Serial No. 372,448.

To all whom it may concern:

Be it. known that 1, ROBERT J. -lVisiworin-a of Great Britain, resi ing at Virginia City, in the county of Storey, State of Nevada, have invented a certain ne and useful Anode; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the artto which itapprriains to make and use the same.

This invention relates to anodes, and more particularly to the anodes used in the precipitation of precious metals from cyanid or like solutions. i

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

It is also desired to provide an anode that can be easily and cheaply renewed or have portions thereot' renewed, if deterioration of the anode should be unequal.

A further object is to render that part of the anode subject to greatest electrochemical action more massive than those parts subject to less action.

Still another object is to provide a simple and convenient construction for an anode which will permit of the parts being made and easily assembled at the place of use and the metallic parts joined together to form a unitary structure readily removable as a whole from thesupport therefor.

With those, and other, objects in view, the invention may be embodied in the form described in this specification, reference being had to the accompanying drawiiw, in which Figure 1 is a side elevation, partly broken away; Fig. 2 is a plan view of a portion of is an end elevatron.

Reference numeral 1 designates a sup porting rail of wood or other suitable materialto which molten metal will not adhere on solidifying, having therein a plurality of holes Qthe rail at the upper part ot said holes being counterbored.' A rod 3, preferably oi lead, is inserted in each of holes 2. and has an enlarged portion t, which rests on the rail of the bottom oi the eounterbo're.

A short distance below rail- 1 the rods are reduced in diameter and about midway of their length and at their lower ends pass through stifi'ening strips 5 and 5 which have dowels '4' driven theret-lu'ough in such a. man ner as to contact with the sides or some of the rods and support the strips. A groove 8 a plurality otrods supported in said rail by is formed in the top of rail 1 and preferably terminates a short distance from each end of said rail. One of rods 3 is provided with a prolongation 9 at its upper end, in which a wire 10 is east and said wire may be connected to any suitable source of electric current. After the rods 3 are assembled in ail 1, melted lead is poured into groove 8, and upon soliditving, it forms a bar 12, connecting the rods 3, whereby current is distributed to all said rods from Wire 10. The molten lead upon solidifying does not ad here to the supporting rail l, so that the rods 3 may be readily removed from position thereon, a unit, when it is desired to make renewal or repairs.

This anode is used in a similar manner to those of the'ordinary construction, as will be readily understood by those skilled in the art to which this invention appertains.

Rods 3 being of larger diameter at the sur face of the fluid, where the. electrochemical action is greatest, do not. become eaten through at this point, as is usually the case, rendering the anode useless.

I claim:

1. In an anode, a supporting rail, a groove therein, openings in said rail, a plurality of rods passing through said openings, on-

larged portions on said rods adapted to rest on the portions of the rail surrounding the openings, and a metallic strip loosely fitting the grooves in said rail and wa ning saidrotls together to form a unitary structure remov-- able frorn said rail.

2. In an anode, a supporting rail of wood,

'a groove therein, counterhored openings in said'rail, a plurality of rods having heads fitting the counterbored portions of said openings, and a metallic strip east. in said grooves joining said rods together, forming a unitary structure removable from said rail.

3. In an anode for electrically precipitnt- .ing metal from solution. a rail, a groove therein, ('ouuierlmred openings in said rail, a plurality oi rods having heads tilting the eounterbored portion of said openings and supported by said rail. an enlarged portion to each of said. rods at the point. oi greatest WWII, and means in the groove. of said rail to eltwtrically connect together said rods and unite them in a unitary structure removable from said rail.

4. In an anode, a

grooved supporting rail,

means of enlargements on the UPIJQP-Glltls, a

metallic strip east in the groove in said rail connecting said rods whereby they are removable as a unit from said rail, a prolongation of one of said rods, and a wire cast: in said prolongation.

5. In an anode for electrically precipitat: ing metal from solution, in combination, a wooden rail provided with opeiiings m'ctallic rods passing through said openings and supported by said rail, said rail provided with grooves extending-between said rods, said grooves adapted to receive molten metal whereby said rods are connected together electrically and mechanically forming a.

structure removable as a unit from said sup-'- porting rail.

6; An anode for electrically precipitating metal from solution, comprising a grooved supporting rail provided with openings therethrough. tapered metallic rods passing through said openings and suppor ed by said rail, metallic strips cast in the groove of said sup 'iorting rail, said strips connecting said rods and il'orininga structure removable from said rail as a unit, and strei'igthening strips associated with said rods.

I 7. In an anode for electrically precipitating metal from solution, in combination, a wooden rail. provided with openings,inetallic rods passing through said openings and supported by said rail, said rail provided with grooves extending between said rods, said grooves adapted to receive molten metal whereby said rods are connected together electrically and ineclianitmlly, forming a unitary structure.

In testin'iony whereof, I have signed my name to this specification in the presence of two subscribing witnesses at Virginia Jity, Storey county Nevada this 23rd day otrpril A. l). 1907.
