Year: 1862

page_text: LETTERS PATENT to Thomas George Webb, of Manchester, in the County
of Lancaster, Flint Glass Manufacturer, for the Invention of "IMPROVE-
WOW IN MY MANUFACTURE OF ARTICLES OF PRESSED GLASS."
Sealed the 27th May 1863, and dated the 4th December 1862.
PROVISIONAL SPECIFICATION left by the said Thomas George Webb at
the Office of the Commissioners of Patents, with his Petition, on the
4th December 1862.
I, THOMAS GEORGE WEBB, of Manchester, in the County of Lancaster,
Flint Glass Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF ARTICLES OF PRESSED GLASS," to be
as follows:
My Invention consists in forming the bottoms of decanters and other
articles of pressed glass in separate portions from the upper parts thereof, and
subsequently attaching them. For this purpose I employ two or more moulds
in which the material is shaped, and while in a heated state the several
moulded parts are brought together.

by the said Thomas George Webb in the Great Seal Patent Office on
the 4th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
GEORGE WEBB, of Manchester, in the County of Lancaster, Flint Glass
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas George Webb, Her special license that I, the said Thomas
George Webb, my executors, administrators, and assigns, or such others as I,
the said Thomas George Webb, my executors, administrators, 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 "IM-
PROVEMENTS IN THE MANUFACTURE OF ARTICLES OF PRESSED GLASS," upon the
condition, amongst others, that I, the said Thomas George Webb, by an
instrument in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
I 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 Thomas George Webb, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say)
'My Invention relates to articles of capacity formed of flint glass, such as
decanters, cruets, pickle jars, and toilets, and consists in a method of producing
the bottoms thereof.
According to the usual process of making these articles, (a decanter, for
instance,) two methods are adopted by which the bottoms are formed. In the
one case the upper part is moulded complete in the first instance, and sub-
sequently the lower part is bent inward to form the bottom. In the other
case the bottom is moulded with the sides, and then the desired shape of the
upper end is produced. It follows according to these modes of operation that
an ornamental design cannot be produced by moulding at both top and

page_text: bottom, for the necessary bending inward of either the one or the other would
distort it from the desired configuration, but according to my Invention that
condition may be attained, and the method by which I accomplish it is to
form the bottom in a mould separate from that which is used for the upper
part. The two portions being thus formed as distinct pieces may be provided
with any design capable of being pressed, after which they are heated (if such
heating be required) to the necessary temperature, and united as is practised
in joining pieces of glass for ordinary purposes. In order to effect a correct
junction I use guides against which to slide the one part so that it may be
adapted to the other centrically. This object may also be attained by leaving
the bottom piece in the mould by which it has been formed, and then effecting
the junction, the said bottom mould in such case constituting the guide.
Having thus described and ascertained the nature of my said Invention,
and the nature of carrying the same into effect, I desire it to be understood
that I claim as secured to me under the above in part recited Letters Patent,
and as applied to such articles as above mentioned, forming the bottoms and
upper parts thereof in separate portions, and then uniting them.
In witness whereof, I, the said Thomas George Webb, have hereunto
set my hand and seal, this Third day of June, in the year of our Lord
One thousand eight hundred and sixty-three.
THOMAS GEORGE WEBB. (L.S.)
