Improvements in Anodes for the Electro-Deposition of Nickel.
I, THOMAS RICHARD CANNING, of the firm of W. Canning & Co., of 137, Great
Hampton Street, Birmingham, in the County of Warwick, Manufacturer, do hereby
déclare the nature of this invention to be as follows:-
This invention relates to improvements in anodes for the electro-deposition of
nickel, the object of the invention being to effect an economy in the cost of manu-
facture and to avoid the necessity of discarding an anode when only partially
consumed.
Hitherto anodes of nickel have been cast or otherwise formed in one piece and of
the required shape. The casting of nickel is costly as is well known and when an
anode has been partly exhausted the whole anode has to be replaced and the
discarded anode is not well suited for recasting.
Now according to my invention these objections are obviated. For this purpose
I build up my anode of small blocks or cubes as they are generally received. from
the refiners except that such blocks or cubes are moulded with a suitably shaped
recess on two opposite sides so that when a number of blocks are built up into an
anode vertical holes will be provided between each superimposed series of blocks
such holes serving to receive connections of carbon or other suitable material... A
suitable frame is employed which, with the connections holds the blocks in
position.
By this construction of anode in addition to employing nickel direct from the
refiners I am enabled, as the blocks become consumed, to replace them without
the necessity of discarding the whole anode.

Improvements in Anodes for the Electro-Deposition of Nickel.
I, THOMAS RICHARD CANNING, of the firm of W. Canning & Co., of 137, Great
Hampton Street, Birmingham, in the County of Warwick, Manufacturer, do hereby
0 declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in anodes for the electro-deposition of
nickel, the object of the invention being to effect an economy in the cost of manu-

page_text: facture and to avoid the necessity of discarding an anode when only partially
consumed.
Hitherto anodes of nickel have been cast or otherwise formed in one piece and of
the required shape.. The casting of nickel is costly as is well known and when an
anode has been partly exhausted. the whole anode has to be replaced and the
discarded anode is not well suited for recasting....
Now according to my invention these objections are obviated. For this purpose
I build up my anode of small blocks or cubes as they are generally received from
the refiners, the said blocks or cubes being held 'in a suitable frame provided with
-connections of carbon or other suitable.material.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which:-
Figure 1 is an elevation of a nickel anode made according to my invention;
Figure 2:is a vertical-section on the line 2-2 Figure 1; and,
Figure 3 is a horizontal section on the line 3-3 Figure 1.
aa are the small-blocks or cubes of nickel with which my anode is built up, the
saids blocks or cubes being, as above described, used exactly as they are usually
received from the refiners. b'is the frame in which the blocks or cubes a.are held
and built up to form an anode. The front of the said frame is formed of lattice or
wickerwork c which suffices to hold the blocks of nickel in the frame the backid of
which is hinged as shewn at-e-so that it can be raised from the anode to provide
access to the nickel cubes a f. is a frame of carbon around the inside of the
frame 6 and around the outside of the plate of nickel cubcs a, the said carboniframe
forming the necessary connection for conveying the current to the cubes-forming
the anode
g; gare carbon" ears connected with the carbon frame:f and adapted for
suspending the anode from hooks on the usual anode rods
With this arrangement of anode in addition to the advantage accruing from
employing the nickel blocks as they arrive from the refiners, that is to say; in
addition to the economy in the manufacture obtained by dispensing. with the
recasting of the nickel blocks, I'am enabled by my invention-to remove and-alter
the position of any of the cubes or blocks a as they are consumed, or to replace
them by fresh cubes without the necessity of discarding. the whole anode, the
construction of the hinged back d enabling the renewal to be easily and
expeditiously effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A nickel anode built up of a number of nickel cubes or blocks as they leave
the refiner and held in a suitable frame and provided with carbon or other suitable
connections, substantially, as, and for the purpose, described!.
2. The manufacture and use of the improved nickel anode hereinbefore described
and illustrated in the accompanying drawing.
