WRIGHT, of the Poultry, in the City of London, Watch Maker, 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
Twenty-fifth day of October, in the seventeenth year of His reign, give and
grant unto me, the said Thomas Wright, His especial licence, that I, the said
Thomas Wright, during the term of years therein expressed, should and
lawfully might use, exercise, and vend, within England, Wales, and Town of
Berwick-upon-Tweed, and also in His Majesty's Colonies and Plantations
abroad, my Invention of "A MILL FOR SQUEESING OR GRINDING OF SUGAR CANES
UPON A NEW CONSTRUCTION, WHICH WILL BE INFINITELY MORE ADVANTAGEOUS TO THE
PUBLICK THAN THOSE NOW IN USE;" in which said Letters Patent there is con-
tained a a proviso obliging me, the said Thomas Wright, 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 inrolled in His Majesty's High Court
of Chancery within four calender months 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
Thomas Wright, do hereby declare that my said Invention of a Mill for
Squeezing or Grinding of Sugar Canes upon a New Construction, which will
