A NEW OR IMPROVED MANUFACTURE OF PLATES OF GLASS
Year: 1870

page_text: LETTERS PATENT to Samuel Neville, of the Ellison Glass Works,
Gateshead, in the County of Durham, for the Invention of "A NEW
OR IMPROVED MANUFACTURE OF PLATES OF GLASS."
PROVISIONAL SPECIFICATION left by the said Samuel Neville at the
Office of the Commissioners of Patents, with his Petition, on the
22nd June 1870.
I, SAMUEL NEVILLE, of the Ellison Glass Works, Gateshead, in the
County of Durham, do hereby declare the nature of the said Invention
for "A NEW OR IMPROVED MANUFACTURE OF PLATES OF GLASS," to be as
follows:-
My Invention has for its object to produce glass plates (more
particularly such as are now made by the process of rolling upon a table)
of a more uniform thickness and even surface on both sides than is
attained by processes at present in use.
It consists in first dropping the
glass in a molten state upon a table and then while the glass is still in a

page_text: plastic condition causing another table to fall from above upon the
surface of the glass, so as to press or squeeze the glass to the size and
thickness required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Neville in the Great Seal Patent Office on
the 17th December 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
NEVILLE, of the Ellison Glass Works, Gateshead, in the County of
Durham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of June, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Samuel Neville, Her special licence
that I, the said Samuel Neville, my executors, administrators, and assigns,
or such others as I, the said Samuel Neville, my executors, adminis-
trators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "A NEW OR IMPROVED MANU-
FACTURE OF PLATES OF GLASS," upon the condition (amongst others) that I,
the said Samuel Neville, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Neville, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say :-
My Invention has for its object to produce glass plates (more par-
ticulary such as are now made by the process of rolling upon a table) of
a more uniform thickness and even surface on both sides than is attained

page_text: by processes at present in use. It consists in first depositing the glass
in a molten state upon a table and then while the glass is still in a plastic
condition causing another table or plate to fall from above upon the
surface of the glass so as to press or squeeze the glass to the size and
thickness required.
For causing the table or plate to descend and press evenly upon the
surface of the glass any suitable known arrangement of mechanisni or
apparatus may be employed whereby a plate or surface may be made to
descend evenly upon another plate or table, and I do not claim any
particular construction of such mechanism; but what I claim is, the
manufacture of sheets or plates of glass by causing a table or plate to
descend and press evenly upon the surface of the glass while spread in a
plastic condition upon another table or plate surface.
In witness whereof, I, the said Samuel Neville, have hereunto set
my hand and scal, this Fifteenth day of December, in the year of
our Lord One thousand eight hundred and seventy.
