AN ODE.

Applicatibnflledlovember 29,1927. Serial No. 236,562.

This invention relates to anodes which are particularly suited for usein electroplating objects of varying-lengths such as, for instance, lamp posts, pipe, etc, 5 The anodes each consist of a rod-of inert conductive material carrying a body; of the anodic metal. The rod is provided with a hook at one end and an eyelet at the other end, both of which project beyondthe main .10 body of anodic metal. Any desired number of the anodes may be hooked together to correspond to the length of the object to be plated by inserting the hook of one anode into the eyelet of another. The anodes may be made in varying lengths. Preferably the bod of anodic metal comprises longitudinal ro ections extending partly around'the eyeet'. These projections are placed in sucha way as not to interfere with the hooking of one anode with another. v

The accompanying drawings illustrate one type of construction of the anodes inaccord= ance with our invention.

Fig. 1 is a front elevation of the anode; Fig. 2 is a top plan view; Fig. 3 is a bottom plan view and Fig. 4 is a side elevation of the anode shown in Fig. 1. v

. The invention is particularly designed and adapted for use in connection with cadmium or Z1110 plating anodes comprising a steel rod as the inert conductive material and cadium or zinc as the anodic metal and will be de- :7

scribed and illustrated such an anode.

In the drawings, A. is a steel core of square cross-section, the upper end of which is formed into the eyelet G and the lower'end into thehook E. Around this core is cast the body B of anodic metal, specifically cadmium. The projections D from the main in connection with body B extend'partly around the eyelet. The 1 projections D preferably are formed as illus-j trated leaving? only a groove in the anodic t5 metal transverse to the plane of the eyelet so that two anodes may be hooked together. I y

The steel core A is shown of square crosssection. but 'ob'viousl itmay be round or of any other form.' A so, the outer. surface of the cast anodic metal may be round'orof any oltlher desired form instead of hexagonal as S 0WD.

gradually eaten away and the anode will .--sooner or.later break, whereas anodes made .the 00k and eyelet. Y

The advantage of these anodes is that they may be very easily hooked together toproduce an anode of any desired length. The weight of the anodic metal is carried entirely bythe inert and relatively strong core... In anodes made entirely of anodic metal without a core of inert metal, the anodic metal is 1n accordance with this invention will not. It has been found that if the steelcore is first electroplated "with'cadmium, the cad-. mium body may becast onto the core much more intimately than if the core is'not electroplated. The breaking oif of the anodic V metal from the core during electrolysis is thus prevented. i

Anodes of the typevdescribed and illustrated have been made of cadmium cast onto a steel core both with and without an'inte'rmediate coating of electroplated cadmium and have been found'to be of particular value for electroplating objects of varying lengths. However, the invention is not limited to cadmium anodes comprising a steel core excepting as may be required. by the terms of the appendei i claims. Many shapes and sizes of the core of inert metal, the hook, eyelet, lugs and cast metal may be designed without departure from the invention. 1 4 I We claim I 1. An anode for use inelectroplating, comprising a coreof inert conductivematerial which is formed into a hook at one end and-an I eyelet at the other end,,said. core having a bod of anodic metal cast around it between v i 2. An anode' for use in electroplating, comprising a core of inert conductive'material which is form'edinto, a hook at one end and an eyelet at .the other. end, said core having a body of anodicmetal cast around it between the hook and eyelet and extending partly aroundthe eyelet in the form of tv'vo'projec tions but leaving the eyelet exposed suflici'ently to allow the hook of another similar anode to be engaged therewith.

3. An anode for use in electroplating, comprising a core of inerticonductive material which is formed into a hook at one end and an eyelet at the other end, said corebeing elec troplated with an anodic metal and having a body of the anodic metal cast around the electroplated core between the hook and eyelet.
