ANODE FOB. USE IN ELECTROPLATING.

Application filled December 13, 1923. Serial No. 680,305.

To all whom imag concern:

Beit made known that I, GIRALDUs JONES, a subject of the King of Great Britain, of 58 St. Oswalds Road, Small Heath Park, Birmingham, England, have invented certain new and useful Improvements in Anodes for Use in Electroplating, of which the following is a specification.

This invention relates to improvements in anodes for use in electro-plating, and refers to anodes particularly adapted for use in the electro-deposition of metals such as nickel or cobalt.

Such metals are commonly placed on the market in the form of small pellets, shot, rondelles or cubes, and one of the objects of my invention is to provide an anode in which the metal can advantageously be used directly in this form without the necessity for melting down and rolling or otherwise forming it into plates or the like.

Another object of my invention is to provide an anode in which the anode metal can vbe rapidly and easily replaced as it is used up without removing the anode from the electro-plating vat or tank so that the plant can be maintained continuously at full working eiiiciency.

A further object of my invention is to provide an anode in which the extent to` which the anode metal has been used up can be seen at a glance by the operator or attendant.

A further object is to avoid the use of solid current leads into the anode container which rapidly wear away, and to make use of the anode metal itself for this purpose.

These and 'other advantages of my improved anode will be apparent by reference to the accompanying drawings in which has been illustrated a convenient practical embodiment of my invention.

In these drawings Figure 1,.is a perspective view of the complete anode.

Figure 2, is avertical section of the upper part of the anode taken through the longer axis.

In the form) illustrated the anode is of hollow box form builtiip from a rectangular skeleton frame of wooden bars or battens a closed on each side by a sheet b of perforated celluloid or like acid proof materiall Secured upon the to face of the upper bar a by screws d is a at metal late e the -lateral dimensions of which are su stantially equal to those of the bar. This plate carries two spaced upstanding lugs f pierced to receive hooks or wires by which the anode is suspended in the electro-plating vat or tank and by which electric current is led to the plate.

The plate e also has at or near the centre of its length a funnel or hopper g, preferably of oval section, which communicates with the interior of the anode through an opening in the plate at the bottom of the hopper and a registering opening h on the top bar a.

The plate e and the hoppery are preferably of the same metal as the plating metal for ,which the anode is to be used.

In use the plating metal in the form of pellets or shot j is adapted to be introduced into the interior of the anode through the hopper g and suiiicient metal is introduced to iill the anode and also wholly or partially to fill the hopper.

Electrical connection to the metal is thus made through the hopper g, plate e, and lugs f so that separate current leads dipping into the shot or pellets are unnecessary.

As the metal in the anode is used up in the electro-plating process it will automatically be replaced by fresh metal feeding down from the hopper, and when the metal in the hopper becomes low this fact will be obvious to the. operator or attendant and the hopper can be at once replenished without diiliculty.

If desired the plate e may be covered ex` ternally with celluloid or other acid proof covering so long as the contact surfaces Within the lugs f and within the hopper ,f/ are left clear.

I claim:

1. An anode for use in electro-plating comprising a hollow box, having perforated sides, a hopper at the top having suspension and current connecting means and communicating with the interior of the anode, the plating metal in divided form being fed into the anode through the hopper and therewith forming the means for conveying current from the anode.

2. An anode for use in electro-plating comprising ahollow box having perforated sides, a metal plate secured upon thevupper face of the box; suspension and current conveying means upon the plate, and a hopper upon the plate communicatin with the interior of the anode through which hopper plating metal in divided form is fed into the anode, and said plate and hopper forming the means for conveying current to said plating metal.

anode for use in electro-plating comprising a rectangular frame of Wooden bars closed on its two open sides by perforated Celluloid sheets secured to the bars, a metal plate secured to the upper face of the top bar, suspension and'current conveying means upon the plate, and a hopper upon the plate and in electrical connection therewith, said hopper communicating with the interior of the Vanode through an opening 'in the top bar of the frame.

4c. An anode for use in electro-plating comprising a hollow box having perforated sides, a metal plate secured upon the upper face of the box, suspension and current conveying means upon the plate, and a hopper upon the plate communicating with the interior of the anode, the said suspension 'and current conveying means comprising .upstanding perforated lugs onthe plate to ture.

GIRALDUS JONES.
