BRASS AND COPPER PLATING, OR PLATING IRON OR STEEL WITH BRASS OR COPPER, BOTH PLAIN AND ORNAMENTAL, AND WORKING THE SAME INTO PLATES, BARS, OR OTHER ARTICLES
Year: 1816

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
POOLE, of Mitre Tavern, Orchard Street, Sheffield, in the County of York,
Victualler, send greeting.
WHEREAS His most Excellent Majesty King George the Third did,
by His Letters Patent under the Great Seal of His United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Third day of
August, in the fifty-sixth year of His reign, give and grant unto me, the said
John Poole, my exors, admors, and assigns, His especial licence, full power,
sole privilege and authority, that I, the said John Poole, my exors, adiňors,
and assigns, should and lawfully might, during the term of years therein
mentioned, make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "BRASS AND COPPER PLATING,
OR PLATING IRON OR STEEL WITH BRASS OR COPPER, BOTH PLAIN AND ORNAMENTAL,
AND WORKING THE SAME INTO PLATES, BARS, OR OTHER ARTICLES;" in which
said Letters Patent there is contained a proviso, that if I, the said John Poole,
shall not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in writing
under my hand and seal, and cause the same to be inrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately after

page_text: the date of the said Letters Patent, that then the said Letters Patent, and all
liberties and advantages whatsoever thereby granted, shall utterly cease,
determine, and become void, as in and by the same (relation being thereunto
had) may more fully and at large appear. [
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Poole, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained as follows, that is to say :-
I take of sal ammoniac (any quantity) and powder and disolve it in as much
water as will just make it into a fluid state, I then take the iron or steel
intended to be plated and rub or bathe the surface whereon the brass or
copper is to be laid with the said prepared sal ammoniac; then I take of
borax (any quantity) and powder and dissolve it in as much water as will just
make it into a fluid state, with which I rub or bathe the surface of the brass
or copper intended to be laid upon the iron or steel. The aforesaid bodies of
metal being laid together, I pack them into a pan or pott with sand or cement,
the better to keep them in their proper places; I then put them into a stove
or furnace, by which they receive from the fire a gradual and progressive heat
until the brass or copper is fluxed or melted upon the iron or steel; I then
take it from the fire to cool, and when cooled the plating is finished. I then
take of these plated metals and roll or beat them, in the usual manner of beating
or rolling metals into plates, sheets, bars, or beadings, and make or work it
into any goods, articles, or purposes wherein the same might or may be found
useful. Where a thin plate of brass or copper is required, I prepare the iron or
steel with the sal ammoniac, as before described; I then warm the same, and
rub or bathe it with the prepared borax; I then take and heat it nearly red
hot in the fire, and immerse or dip it into a pot of melted brass or copper,
from which I take it out and immediately strike it with a hammer, or other fit
instrument, to cause a vibration, so that as much of the superfluous particle of
the brass or copper may drop off as possible, and a slight covering of plate will
still remain upon the iron or steel. The ornamental process or design intended
to be plated must be first made in the iron or steel by a sunken or engraved
impression, and the brass or copper is laid on by the same process as first
described, which is afterwards worked so as to shew the brass or copper
plated in the original impression. I also make the plain plate ornamental
by filing, cutting, or grinding off the brass or copper (according to the purpose
for which the article is intended, or according to fancy), so as to shew the

page_text: iron or steel. Great care must be taken to make the metals quite free from
rust, scale, or grease before the process of the plating is begun.
In witness whereof, I, the said John Poole, have hereunto set my hand.
and seal, this Twenty-fifth day of January, in the year of our Lord One
thousand eight hundred and seventeen.
