Year: 1817

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TURNER, of Birmingham, in the County of Warwick, Button Maker, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifth day of December,
in the fifty-eighth year of His reign, give and grant unto me, the said John
Turner, my exors, adñors, and assigns, His especial licence, full power, sole
privilege and authority, that I, the said John Turner, my exors, adiñors, and
assigns, should and lawfully might, during the term of years therein expressed,
make, use, exercise, and vend within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN
PLATING OF COPPER OR BRASS, OR A MIXTURE OF COPPER AND BRASS WITH
PURE OR STANDARD GOLD, OR GOLD MIXED WITH A GREATER PORTION OF ALLOY,
AND IN. THE PREPARATION OF THE SAME FOR ROLLING INTO SHEETS;" in which
said Letters Patent there is contained a proviso that if I, the said John Turner,
should 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 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:

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Turner, 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 in and by the following description thereof (that is say):-
I first prepare ingots or pieces of copper or brass, or a mixture of copper
and brass, in such convenient lengths and sizes as I may require. I then
clean such ingots or pieces from impurity, and make their surfaces as level as
may be. I next prepare pieces or plates of pure or standard gold, or gold
mixed with a greater portion of alloy, of the same or nearly of the same sizes
as the ingots or pieces of metal, and of such strength or thickness as I may
require. I then place a piece of pure or standard gold, or gold mixed with a
greater portion of alloy, upon an ingot or piece of metal intended to be plated,
and hammer and compress them-both-together-so that they may have their sur-
faces as nearly equal to each other as possible. I then bind them together, either
with wire or by any other method; in order to keep them in the same position
during the process required to. attach and combine them together. I next
take silver filings or silver cut into strips or pieces, or filings or strips of silver
mixed with a portion of alloy, either of which I mix with borax, or any other
salt or substance calculated to assist the fusion of the silver. Of this mixture
I take a portion and place it or lay it upon and along the edge of the piece or
plate of gold, and next to the ingot of metal, so that the said mixture of silver
and borax or other salt may lie and rest upon the edge or between the edges
of the piece or plate of gold and the ingot of metal. Having thus prepared the
two bodies or metals of pure or standard gold, or gold mixed with a greater
portion of alloy and copper or brass, or a mixture of copper and brass, I place
them upon a fire in a stove or furnace, &c., where they remain until the silver
and borax so placed along the edges of the metals melt and become in a state
of fusion, and until the adhesion to or combination of the gold with the metal
is perfect. I then take the ingot carefully out of the stove or furnace, &c.
By this process the ingot is plated with gold and prepared ready for rolling
into sheets. I mention this as one way of combining and connecting the gold
with metal by placing the ingot in a stove or furnace, &c., but it may be
effected by many other ways where sufficient heat can be applied to the gold
and metal to effect the fusion of the silver and the adhesion of the gold to the
copper, &c.. I also effect the adhesion of the gold to the copper, &c. I also
effect the adhesion of the gold to the copper, &c., without the assistance or the
use of any portion of silver mixed with the borax or salt, by merely using
other. kinds of solder, but the mode I. prefer is as above stated..
I do not, in these my improvements of plating copper or brass, or copper-

page_text: and brass mixed with gold, lay claim to any particular new mode or prepa-
ration of the copper or brass, or copper and brass mixed; nor do I bind myself
to any particular mixture of the said metals as respects proportion, nor to any
particular mixture of the said metals as respects proportions, nor to any
particular mixture or portions of the gold and alloy, neither in the silver or
silver and alloy, because I use either silver alone or silver and alloy mixed
with the borax in such proportions as I find most suited to my purpose, or I
use other kinds of solder; nor do I lay claim to any particular method of
applying heat to the two bodies of gold and metal intended to be combined,
but leave myself at liberty to use any and all the methods most convenient for
my purpose; but the improvements of plating copper or brass, or copper and
brass mixed with pure or standard gold, or with gold mixed with a greater
portion of alloy, so that when plated it may be rolled into sheets. For these
improvements alone I do claim the exclusive privilege.
In witness whereof, I, the said John Turner, have hereunto set my
hand and seal, this Third day of June, in the year of our Lord One
thousand eight hundred and eighteen.
Inrolled the Fourth day of June, in the year of our Lord One thousand
eight hundred and eighteen.
