YATES, of Bordsley, in the Parish of Aston near Birmingham, in the County
of Warwick, Brass Founder, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date the
Eighth day of July, in the twenty-eighth year of His reign, give and
grant unto me, the said James Yates, His especial licence that I, the said
James Yates, during the term of years therein expressed, should and
lawfully might use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "A NEW METHOD OF MULTIPLYING
ENGRAVINGS OR CHASINGS ON ALL KINDS OF METALS, PARTICULARLY APPLICABLE TO
THE ENGRAVINGS OR CHASINGS ON THE ORNAMENTS OF COACHES AND COACH HARNESS,
AND MANY OTHER PURPOSES WHERE ENGRAVINGS OR CHASINGS ARE REQUIRED;" in
which said Letters Patent there is contained a proviso obliging me, the said
James Yates, under my hand and seal, to cause a particular description of
the nature of my said Invention, and how the same is to be performed,
to be enrolled in His Majesty's High Court of Chancery within one calendar
month after the date of the said recited Letters Patent, .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
James Yates, do hereby declare that my said Invention is described in manner
following, that is to say :-

page_text: The design is engraved on a solid block of steel, iron, copper, brass, or
other mixed metal, made in any form or size required. It is then fixed in a
dye of iron, steel, or other metal, which dye has a ring or collar round it so as
to form a kind of dish, the ring on the outside of which raising higher than
the engraved block. A forcer or block of metal is then impressed upon the
engraving, and, with thin plates of soft tin or lead or mixed metal, is laid
under a stamp or press, by the force of which a perfect impression is made
from the engraved block. Thin plates of metal; of gold, silver, plated metal,
copper, brass, or other mixed metals, are then impressed or stamped, and the
raised side of the impression of engraving is then filled with melted metal of
lead, tin, or any other mixed metal, or hard cement, to any thickness required,
so that the reverse side has the perfect appearance of the original engraved
block or pattern, and any number of impressions may be taken off. For some
purposes a steel, iron, or other metal roll is engraved of any design required,
and an impression taken off by another counter roll of metal, and then plates
of thin metal of any kind are passed between the rollers by the force of a mill,
and the raised side of the impression is afterwards filled with metal, &c., as
before described.
In witness whereof, I, the said James Yates, have hereunto set my
hand and seal, this Thirty-first day of July, One thousand seven
hundred and eighty-eight.
AND BE IT REMEMBERED, that on the Thirty-first day of July, the
aforesaid James Yates came before our Lord the King in His Chancery,
and acknowledged the Specification aforesaid, and all and every thing therein
contained and specified, in form above written. And also the Specification
aforesaid was stampt according to the tenor of the Statutes made for that
purpose.
