FRUVIDIONAL SPECIFICATION.
Process for the Prevention of Articles, Made of Rustable Metals or
Alloys, Rusting after they are Electro-plated.
CHARLES MASON Artist and Art Manufacturer Grey Street Hull do hereby
declare the nature of this invention to be as follows:-
A process or method by means of which I prevent all articles made of any
rustable metals such as iron, steel, etc., or any oxidisable alloys, rusting (as they do
at present) after they are electro plated.
I first clean the articles to be plated by the ordinary methods generally employed
in electro-plating as follows firstly I place them in a hot or boiling solution of
caustic potash or soda to remove all grease, after which I place them in any suitable
acid solution or "pickle" to remove all oxide, after the articles are thus cleaned
I immerse them in a solution of caustic potash or soda to neutralise the acid.
I then wash them in clean water and place them in a solution of tin, or zinc or a
solution of tin and zinc, and submit the articles to a steady electrical current until
a preliminary deposit of a suitable thickness of tin or zinc, or an alloy of tin and
zinc is deposited upon them. I then wash the articles in clean water, and place
them in a solution of whatever metal or alloy they are required to be plated with,
and finish them in the ordinary manner of electro-plating.

CHARLES MASON, Artist and Art Manufacturer, Studio, Grey Street, Hull 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
I first clean the articles to be plated by the ordinany methods generally employed
in electro plating, firstly I place them in boiling soda or potash to remove all grease,
after which I dip them in any suitable acid dip or "pickle." I then wash them in
clean water, and place them in a solution of tin, or of zinc, or a solution of tin and
zinc and submit them to a steady electrical current until a preliminary deposit of a
suitable thickness of tin or of zinc or an alloy of tin and zinc is deposited upon
them. I then wash the articles in clean water, and place them in a solution of
whatever metal or alloy they are required to be plated with, and finish them in
the ordinary manner of electro plating.
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 :
I claim the application of the preliminary coating or deposit of tin, or of zinc

page_text: or alloy of tin and zinc to the surfaces of all articles made of iron, steel, or other
rustable metals or alloys, for the specific purpose of preventing all such articles
rusting after they are electro-plated.
