PROVISIONAL SPECIFICATION.
Improvements relating to the Electro Deposition of Metal.
I, HOWARD WILKINS WRIGHT, of the Firm of Wright and Butler, of 390, New
John Street West, in the City of Birmingham, Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention consists of improvements relating to the electro-deposition of
metal on iron castings employed in the manufacture of lamps and stoves, and
on other articles, my object being to obtain in a ready and economical manner
a more effective appearance from such plating, than by the ordinary methods
at present in general use.
In the application of my invention to the "electro-brassing" of iron castings
employed in the manufacture of lamps and stoves, I first galvanize or tin such
castings in any ordinary manner, without any prior "scratching" or like prepara-
tion of the surfaces. I then subject the galvanized articles to the electro-brassing
process, after the surfaces have been prepared by a scratching" or other like
operation.
<
By galvanizing or tinning the articles before subjecting them to the electro-
brassing process, I am enabled to readily obtain a very effective and finished
appearance of their surfaces. With my improved method I am also enabled to
dispense with the preliminary electro-deposition of copper upon the articles to
be subsequently plated with brass, such as is usual with the ordinary method of
electro-brassing.
My invention is applicable to the electro-deposition of copper and other metals
upon cast iron or other articles upon which an effective and non-corrosive surface
is required.

I, HOWARD WILKINS WRIGHT, of the Firm of Wright and Butler, of 390, New
John Street West, in the City of Birmingham, Manufacturers, do hereby declare
the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-

In the application of my invention to the " electro-brassing" of iron castings
employed in the manufacture of lamp stoves, I first galvanize or tin such castings
in any ordinary manner, without any prior "scratching" or like preparation of
the surfaces. I then subject the galvanized or tinned articles to the electro-
brassing process, after the surfaces have been prepared by a "scratching" or other
like operation.
By galvanizing or tinning the articles before subjecting them to the electro-
brassing process, I am enabled to readily obtain a very effective and finished
appearance of their surfaces. With my improved method of forming an under-
coat for the plating metal I am also enabled to dispense with the preliminary
electro-deposition of copper upon the articles to be subsequently plated with
brass, such as is usual with the ordinary method of electro-brassing.
My invention is applicable to the electro-deposition of copper and other metals
upon cast iron or other articles upon which an effective and non-corrosive surface
is required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The improvements relating to the electro-deposition of metal on iron castings
and other articles, comprising the galvanizing and tinning of such articles to
form an under-coat for the electro-deposited metal, substantially as described.
2. The improved method of electro-brassing iron castings, substantially as
described.
