Year: 1818

page_text: TO ALL TO WHOM. THESE PRESENTS SHALL COME, I; EDWARD
WOOLLEY, of Bilston, in the County of Stafford, Screw Manufacturer, 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 Tenth day of
November, in the fifty-ninth year of His reign, give and grant unto me, the
said Edward Woolley, my exors, admors, and assigns, His especial licence,
full power, sole privilege and authority, that I, the said Edward Woolley,
my exors, admors, 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 IMPROVE-
MENTS IN MACHINERY FOR MAKING WOOD-SCREW FORGINGS;" in which said Letters
Patent there is contained a proviso, that if .I, the said Edward Woolley, 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 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
Edward Woolley, 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 to say) :-
The machinery may be worked by manuel labour, horses or other cattle,
steam, water, or any other power. The screw forging is formed or shaped
from round or cylindrical rod iron, which is cut off, either in a hot or cold
state, into proper lengths by a pair of shears, and then put into a mould,
commonly called a bore, which bore has a hole in it the size of the screw, and
countersunk at top, and held by a pair of clamps or vice underneath, then
struck by a stamp working by perpendicular slides or by a press, either
perpendicular or horizontal, which forms the shank into a taper or conical
shape, and also forms the head of the forging at one blow, which, by the
operation aforesaid, is made fit for the purpose of being formed into a screw in
the usual way, and which forgings, before the said Invention, had always been
forged by hand and not by machinery; the clamps or vice underneath the
bore are closed, to hold the shank of the forging, by an horizontal screw, while
the blow is struck, and opened by the same means, and which horizontal screw
is moved by a lever or crank.
In witness whereof, I, the said Edward Woolley, have hereunto set my
hand and seal, this Seventh day of May, in the year of our Lord One
thousand eight hundred and nineteen.
Inrolled the Eighth day of May, in the year of our Lord One thousand
eight hundred and nineteen.
