CERTAIN IMPROVEMENTS IN THE MANUFACTURING AND WORKING OF VARIOUS KINDS OF GLASS
Year: 1805

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SCOTT, of the London Glass Works, East Smithfield, in the County of Middle-
sex, Glass Manufacturer, send greeting.
WHEREAS His present most Excellent Majesty King George the Third,
in and by His Letters Patent under His Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Ninth day
of August, in the forty-fifth year of His reign, for Himself, His heirs and
successors, did give and grant unto me, the said William Scott, my executors,
administrators, and assigns, His especial license, full power, sole privilege
and authority, that I, the said William Scott, my executors, administrators,
and assigns, and every of them, by myself and themselves, or by my and their
deputy or deputies, servants or agents, or such others as I, the said William
Scott, my executors, administrators, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within that part of His said Majesty's United Kingdom called
England, His Dominion of Wales, and the Town of Berwick-upon-Tweed, my
Invention of "CERTAIN IMPROVEMENTS IN THE MANUFACTURING AND WORKING OF
VARIOUS KINDS OF GLASS;" in which said Letters Patent there is contained a

page_text: proviso obliging me, the said William Scott, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the nature of my
said Invention, and in what manner the same is to be performed, and to cause
the same to be inrolled in His said Majesty's High Court of Chancery
within one calendar month next and immediately after the date of the said
recited Letters Patent, as in and by the same, relation being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Scott, do hereby describe and ascertain the nature of my said Invention,
and the manner in which the same is to be performed, as follows, that is to
say:-
The object of my Patent is to grind and polish glass of various species of
a thinner substance than has hitherto been practised, and rendering such fit
for window sashes, mirrors, or looking glasses, either from plate, crown, or
flint glass, by flashing or expanding such in the process of manufacturing by
a rotative motion, in a similar manner to window glass, preserving such thick-
ness in the blowing as may be deemed necessary; when drawn from the
annealing kilns, to be cut into squares or panes, placing one, two, or more upon
each other, in spreading or annealing kilns, upon flat surfaces of stone, glass,
or other substances, and producing such degree of heat as will cause the glass
to give or yield to the even surface it is placed upon, thereby becoming flat
and fit for grinding, and for polishing without grinding, rendering such fit for
silvering, at which time the fire should be withdrawn. Also to grind and
polish shut or spread glass as has not been made, used, or intended for that
purpose, namely, grinding, and polishing, by flattening, as above described, or
by buckling, tying, or fixing such to beds of plaster for grinding and for
polishing. The methods hitherto usually adopted for manufacturing plate
glass intended for such purposes, namely, grinding and polishing, are, either by
blowing cylinders and cutting them open at each end with shears, or casting
on metal tables; either of which processes necessarily requires a thickness or
substance greatly exceeding the mode I have here proposed.
In witness whereof, I, the said William Scott, have hereunto set my
hand and seal, this Ninth day of September, in the forty-fifth year
of the reign of our Sovereign Lord George the Third, by the grace
of God of the United Kingdom of Great Britain and Ireland King,
Defender of the Faith, in the year of our Lord One thousand eight
hundred and five.
