CHARLES GRIERSON, of New Bond Street, in the Parish of Saint George,
Hanover Square, and County of Middlesex, Gunmaker, şend greeting.
WHEREAS His most Excellent Majesty King George the Third,
did, by His Letters Patent under the Great Seal of His United Kingdom,
bearing date at Westminster, the Sixteenth day of December, in the
forty-second year of His reign, give and grant unto me, the said Charles
Grierson, His especial licence that 1, the said Charles Grierson, during
the term of years therein mentioned, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of
Berwick upon Tweed, my Invention of "A BREECH AND LOCK FOR SINGLE
AND DOUBLE BARREL GUNS, PISTOLS, AND OTHER FIRE-ARMS ON A NEW OR
IMPROVED PRINCIPLE;" in which said Letters Patent there is contained a
proviso, obliging me, the said Charles Grierson, by an instrument in
writing under my hand and seal, to cause a particular description of the
nature of my said Invention, and in what manner the same is to bei
performed, to be inrolled in His Majesty's High Court of Chancery
within one calendar month after the date of the said recited Letters
Patent.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the
said Charles Grierson, do hereby declare that my said Invention is
described in the Drawings and description thereof in the margin of
these Presents, and in manner following, that is to say:
:
The principle of this new invented or improved breech, lock, plate,
or pan for single barrell'd guns, pistols, and other fire-arms, is, that it
has a quicker communication from the anti-chamber of the breech to
the center of the barrel on a more perfect construction than any other
Invention. It operates with the greatest velocity, not so liable to hang
fire, and is much easier cleaned. This Invention is also of the greatest
utility to the stock, as it strengthens the weakest part, 1st, by sloping
off the unnecessary metal from the touch hole side of the breech to gain
a quick communication from the pan to the anti-chamber of the breech
which leads to the centre of the charge in the breech to the barrel; the
slope of the plate for pan being also constructed to fit the breech.
24, the pan or part of it may be constructed from the breech to have
near the same advantage, but cannot be so perfect nor so easily cleaned
as the pan constructed from the plate of the lock. The opposite side of
the breech to the lock, when thought necessary, being sloped off, gains
the above described strength to the stock. 34, the double barrel gun
and pistol breeches are constructed on the same principles as the single
barrel gun breech. The touch hole sides of the breeches being sloped
off brings the locks of a double barrel gun nearer together; by. this.
improvement the cocking of the left lock becomes perfectly easy.
:..
In witness whereof, I, the said Charles Grierson, have hereunto
set my hand and seal, this Sixteenth day of January, in the year
of our Lord One thousand eight hundred and two.
