Ax IMPROVED METHOD OF COATING IRON AND OTHER METAL WITH TIN
Year: 1875

page_text: LETTERS PATENT to Reginald James Blewitt, of Upper Norwood,
in the County of Surrey, Gentleman, for the Invention of "Ax
IMPROVED METHOD OF COATING IRON AND OTHER METAL WITH TIN.”
PROVISIONAL SPECIFICATION left by the said Reginald James
Blewitt at the Office of the Commissioners of Patents, with his
Petition, on the 11th December 1875.
I, REGINALD JAMES BLEWITT, of Upper Norwood, in the County of
3 Surrey, Gentleman, do hereby declare the nature of the said Invention
for "AN IMPROVED METHOD OF COATING IRON AND OTHER METAL WITH TIN," to
be as follows:-
:
The object of my Invention is a method or process of readily and
cheaply coating iron and other metals which will receive a coating of
tin with that metal.
My Invention consists in forming a solution of stannate of soda of
any suitable strength, and in immersing therein the metal plate or

page_text: object to be coated, leading a current of electricity or magnetism
through the article. The electric or magnetic current causes the metal
article to gather to its sides the tin from the solution of stannate of
soda. I remove the article from the solution when a sufficient coating
has been gathered, and finish it afterwards as may be desirable.
By the above method, as can be at once understood, a great saving
of tin is effected, and the tedious and costly preparation which has now
to be undergone by the iron before coating is dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Reginald James Blewitt. in the Great Seal 1
Patent Office of the 10th June 1876...
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, REGINALD

NOW KNOW YE, that I, the said Reginald James Blewitt, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed; to be particularly described and ascer-
tained in and by the following statement thereof, that is to say :-
The object of my Invention is a method or process of readily and
cheaply coating iron and other metals which will receive a coating of
tin with that metal.
My Invention consists in forming a solution of stannate of soda of
any suitable strength, and in immersing therein the metal plate or
object to be coated, leading a current of electricity or magnetism
through the article. The electric or magnetic current causes the metal
article to gather to its sides the tin from the solution of stannate of
soda. I remove the article from the solution when a sufficient coating
has been gathered, and finish it afterwards as may be desirable.
By the above method, it can be at once understood, a great saving
of tin is effected, and the tedious and costly preparation which has now
to be undergone by the iron before coating is dispensed with.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim, the
improved method of coating iron and other metal with tin as herein-
before described.
In witness whereof, I, the said Reginald James Blewitt, have
hereunto set my hand and seal, this Ninth day of June, One
thousand eight hundred and seventy-six.
REGINALD J. BLEWITT. (L.S.)
