Year: 1817

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WALL, of Wandsworth, in the County of Surrey, Watchmaker, 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, First day of February, in the
fifty-seventh year of His reign, give and grant unto me, the said William Wall,
my exors, adiñiors, and assigns, His special licence, full power, sole privilege
and authority, that I, the said William Wall, my exors, adñiors, and assigns,
should and lawfully might, during the term of years therein mentioned, make,
usc, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "A NEW OR IMPROVED HORIZONTAL ESCAPEMENT
FOR WATCHES;" in which said Letters Patent there is contained a proviso, that
if I, the said William Wall, 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 two 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Wall, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are particularly described
and ascertained in the following description (that is to say) :-
The principles of this Patent are contained in performing its actions or
vibrations with two escape wheels fixed on separate arbors or axis. The first
escape wheel is fixed on the fourth wheel arbor or axis. The second escape
wheel is fixed on the fifth wheel arbor or axis. The escape wheels are
supported in opposite revolutions by the fourth and fifth wheels acting acting
on the said arbors or axis, which conducts the escape wheels through their
actions on the pallate, pallates, or cylinder, which is formed in the rib or staff
of the balance. The teeth of the escape wheels may be shaped as the common
dead-beat swing wheel; but the shape of the tooth and the face of the pallate,
pallates, or cylinder may be formed, to the pleasure of the workman, to produce
long or short vibrations, which has no concern with my Patent.
In witness whereof, I, the said William Wall, have hereunto set my hand
and seal, this Eleventh day of March, in the year of our Lord One
thousand eight hundred and seventeen.
WILLIAM (L.B.) WALL
AND BE IT REMEMBERED, that on the Eleventh day of March, in the
year of our Lord 1817, the aforesaid William Wall came before our said 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 stamped according to the tenor of the
Statute made for that purpose.
