PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Use in Electro-deposition.
We, THE COWPer-Coles GalvANIZING SYNDICATE LIMITED of 39 Victoria
Street, in the City of Westminster and SHERARD OSBORN COWPER-COLES, of
16 Adam Street, Manchester Square, in the County of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
In apparatus for effecting electro-deposition it is generally desirable that the
anodes should be situated as near to the cathodes as possible but in such apparatus
as hitherto arranged, they cannot be brought together so nearly as is desirable on
account of the articles upon which the deposition is made-constituting the cathodes
necessitating the allowance of considerable space between the anodes and cathodes--
for the placing of the said articles in the bath and their removal therefrom after
coating. It is the object of this invention to provide an arrangement whereby not
only can the articles to be coated be easily put in place in the bath and removed
therefrom but the anodes are also in the desirable close proximity thereto, the
arrangement being moreover, simpler, cheaper, and generally more convenient, than
are the arrangements hitherto in use.
According to this invention, the cathodes, that is, the articles to be coated, are
carried by conductive cross-pieces or bridge-pieces to which the said cathodes are
attached in any convenient way, for example, by conductive holders connected
thereto.
The anodes are supported by conducting bars or girders and upon these are
placed the conductors for the cathodes the said conductors being insulated from
the bars or girders carrying the anodes. The cross-pieces or bridge-pieces
carrying the cathodes or articles to be coated are then placed upon the cathode
conductors supported as aforesaid upon the bars or girders which carry the anodes,
one end of the said cross-pieces or bridge-pieces resting on one conductor and the
other upon the other conductor on the respective bars or girders carrying the
anodes. The articles having been secured in their holders they can be readily
introduced vertically into the bath until the cross-pieces or bridge-pieces rest on
the cathode conductors on the bars or girders carrying the anodes the one set of
bars or girders thus supporting both the anodes and the cathodes.

Improvements in Apparatus or use in Electro-u¤posimon.
We, THE COWPER-COLES GALVANIZING SYNDICATE LIMITED of 39 Victoria
Street in the City of Westminster and SHERARD OSBORN COWPER-COLES of
16 Adam Street Manchester Square in the County of London Engineer, do
hereby declare the nature of this invention and in what manner the same is to be

page_text: performed to be particularly described and ascertained in and by the following
statement :-
In apparatus for effecting electro-deposition it is generally desirable that the
anodes should be situated as near to the cathodes as possible, but in such apparatus
as hitherto arranged they cannot be brought together as nearly as is desirable on
account of the articles upon which the deposition is made constituting the cathodes
necessitating the allowance of considerable space between the anodes and cathodes
for the placing of the said articles in the bath and their removal therefrom after
coating. It is the object of this invention to provide an arrangement whereby not
only can the articles to be coated be easily put in place in the bath and removed
therefrom but the anodes are also in the desirable close proximity thereto, the
arrangement being moreover simpler cheaper and generally more convenient than
are the arrangements hitherto in use.
According to this invention the cathodes that is, the articles to be coated, are
carried by conductive cross pieces or bridge pieces to which the said cathodes are
attached in any convenient way, for example, by conductive holders connected
thereto.
The anodes are supported by conducting bars or girders and upon these are
placed the conductors for the cathodes the said conductors being insulated from the
bars or girders carrying the anodes. The cross-pieces or bridge-pieces carrying
the cathodes or articles to be coated are then placed upon the cathode conductors
supported as aforesaid upon the bars or girders which carry the anodes, one end of
the said cross-pieces or bridge-pieces resting on one conductor and the other upon
the other conductor on the respective bars or girders carrying the anodes. The
articles having been secured in their holders they can be readily introduced
vertically into the bath until the cross-pieces or bridge-pieces rest on the cathode
conductors on the bars or girders carrying the anodes the one set of bars or girders
'thus supporting both the anodes and the cathodes.
The accompanying drawing represents part of an electrolytic vat provided with
an arrangement according to this invention so much only of the complete arrange-
ment being shewn as is necessary to render the description clear, the details of
construction may however be varied considerably without departing from the
nature of the said invention. Figures 1 and 2 are sections at right angles to each
other and Figure 3 a plan corresponding to Figure 1.
A is the vat having on its opposite sides or ends strips or bars a of copper and
these strips are connected to one pole of the electric generator. On the strips are
placed at any convenient distances apart any desired number of pairs of bars or
girders B which may be of iron having connected thereto strips of copper b and
provided at their ends with feet a preferably of copper which rest upon the strips
or bars a. To these bars or girders B and the copper strips are secured by
means of screws brackets or pieces c to which are connected by screws
carriers C to which the anodes C are secured. The several anodes carried by
each pair of bars or girders B are preferably connected together at their lower
ends by iron bars C³ whereby increased rigidity is given to the girders B. On the
top of the girders B are strips or bars D of insulating material (preferably wood
treated with paraffin) on which are supported cross pieces or bridge-pieces E
strips d preferably of copper being interposed between the said bridge-pieces and
the bars of insulating material, which strips are connected to the other pole of
the electric generator.
The bars or girders B may be of iron or other suitable material and the brackets
or pieces e to which the anode carriers are connected can be of copper or its alloys.
The cross pieces or bridge-pieces E are preferably of copper or gun metal. The
cathodes or articles to be coated may be suspended from the said cross pieces or
bridge-pieces in any convenient manner. In the drawing the said bridge pieces
are shewn provided with depending arms E' to the lower ends of which the articles
to be coated can be secured by clamping screws F.

page_text: Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In apparatus for use in electro deposition, bars or girders for supporting the
anodes and having conductive cross-pieces or brid ge-pieces, resting upon them but
insulated from them, for supporting the cathodes or articles to be coated the said
bars or girders and cross or bridge-pieces being in electric connection with the
respective poles of the electric generator substantially as herein before described.
2. The arrangement and combination of parts hereinbefore described and
illustrated by the accompanying drawings for carrying or supporting the anodes
and cathodes in electro deposition apparatus.
