Year: 1874

page_text: LETTERS PATENT to Henry John Brook, Edward Goodrick Draper,
and John Unwin, all of Sheffield, in the County of York, Electro-
platers, for the Invention of "IMPROVEMENTS IN THE PREPARATION OF
ARTICLES TO BE ELECTRO-PLATED OR COATED WITH NICKEL AND OTHER METALS
BY ELECTRICITY."
Sealed the 23rd October 1874, and dated the 29th April 1874.
PROVISIONAL SPECIFICATION left by the said Henry John Brook,
Edward Goodrick Draper, and John Unwin at the Office of the
Commissioners of Patents, with their Petition, on the 29th April
1874.
We, HENRY JOHN BROOK, EDWARD GOODRICK DRAPER, and JOHN
UNWIN, all of Sheffield, in the County of York, Electro-platers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE PREPARATION OF ARTICLES TO BE ELECTRO-PLATED OR COATED WITH NICKEL AND
OTHER METALS BY ELECTRICITY,” to be as follows:-
Our Invention relates to and consists in the use of two certain sub-
stances, such as lime and rouge to be used either separately or combined

page_text: in preparing articles to be electro-plated or coated with nickel and other
metals.
Hitherto in the preparation of articles to be coated with metals they
have been subjected to washing in various solutions, such as potash,
soda, acids, alkalies, and other liquids, all of which are dispensed with
by our improved method of preparation, which is as follows:-We take
the ordinary quicklime and pound it very fine and then add a certain
portion of rouge making a smooth fine powder, the same is then applied
to the articles with a suitable piece of cloth or leather carefully rubbing
every part until all grease or dirt be removed from them. They are
then placed in a dry state in the bath or solution to receive the deposit
of nickel or other metals.
The use of the lime is to free the articles from grease and dirt and
the rouge. to give them a certain kind of polish, and more or less of the
latter is used for this purpose, but when polish is not required we use
lime only.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry John Brook, Edward Goodrick Draper, and
John Unwin in the Great Seal Patent Office on the 28th October
1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
JOHN BROOK, EDWARD GOODRICK DRAPER, and JOHN UNWIN, all of
Sheffield, in the County of York, Electro-platers, send greeting.
WHEREAS Her most Gracious Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of April, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry John Brook, Edward Goodrick
Draper, and John Unwin, Her special licence that we, the said Henry.
John Brook, Edward Goodrick Draper, and John Unwin, our executors,
administrators, and assigns, or such others as we, the said Henry John
Brook, Edward Goodrick Draper, and John Unwin, our executors, ad-
ministrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein

page_text: expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE PRE-
PARATION OF ARTICLES TO BE ELECTRO-PLATED OR COATED WITH NICKEL AND OTHER.
METALS BY ELECTRICITY," upon the condition (amongst others) that we,
the said Henry John Brook, Edward Goodrick Draper, and John Unwin,
our exccutors, or administrators, by an instrument in writing under our,
or one of our, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Scal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry John Brook, Edward
Goodrick Draper, and John Unwin, do hereby declare the nature of the
said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement in writing, that is to say :-
This Invention relates to and consists in the application and use of two
certain substances, such as lime and rouge to be used either separately
or combined in preparing articles to be electro-plated or coated with
nickel and other metals.
Hitherto in the preparation of articles to be coated with metals they
have been subjected to a washing or washings in various solutions, such
as potash, soda, acids, alkalies, and in other liquids, all of which are
dispensed with in our improved method of preparation, which is as
follows: We take the ordinary quicklime and pound it very fine and
then add to it a certain portion of rouge making a smooth fine powder.
Or we may also take a solution of sulphate of iron, and these substances
we mix with any quantity of dry lime, and after the decomposition is
complete we dry the mass in order to be used in our improved method or
process. The same is then to be applied to the articles with a suitable
piece of cloth or leather carefully rubbing every part until all grease or
dirt is removed from them. The articles are then placed in a dry state
in the bath or solution to receive the deposit of nickel or metals.
The use of the lime is intended to free the articles from grease and
dirt and the rouge is to give them a certain kind of polish and more or
less of the rouge is to be used for this purpose, but when a polish is not
required we use lime only.

page_text: Having now described the nature and object of our said Invention and
in what manner the same is to be performed or carried out in practice,
we have to state in conclusion that we claim, the use of dry lime and
rouge mixed or prepared and used as above described (or used separately
when required) for the purpose of preparing articles to be electro-
plated or coated with nickel and other metals, the articles thus
prepared being introduced into the bath dry and free from all liquids.
จ
In witness whereof, I, the said John Unwin, on behalf of the said
Henry John Brook, Edward Goodrick Draper, and myself, have
hereunto set my hand and seal, this Twenty-second day of
October, in the year of our Lord One thousand eight hundred and
seventy-four.
