page_text: LETTERS PATENT to Thomas Young Hall, of the Town and County
of Newcastle-upon-Tyne, Coal Owner, for the Invention of "IM-
BRAVEHEN IN COMING
PROVISIONAL SPECIFICATION left by the said Thomas Young Hall
at the Office of the Commissioners of Patents, with his Petition,
on the 9th August 1858.
Sp
I, THOMAS YOUNG HALL, of the Town and County of Newcastle- Pr
upon-Tyne, Coal Owner, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN COMBINING GLASS WITH OTHER MATERIALS"
to be as follows:-
This Invention consists in the combination with glass of metal,
transparent or partially transparent, such as wire gauze, perforated
copper, platina, talc, &c., for the purpose of increasing the durability of
the glass without materially interfering with its transparency. This
may be effected by fusing such metals or other materials with the glass,
or by imbedding the other materials in the glass when in a plastic
state, or in any other convenient method. A sheet of wire gauze,

page_text: perforated copper, or other metal may be laid between two plates of
glass, giving great stability to the same, and rendering it applicable to
various useful purposes, such as the frouts of fire grates, lamp chimneys
and shades, and vessels and utensils of various kinds, as well as for
illuminating purposes, when the glass is subjected to rough usage, as the 5
deck-light of a shin's cabin. for example.
SPECIFICATION in pursuance of the conditions of the Letters Pafent,
filed by the said Thomas Young Hall in the Great Seal Patent
Office on the 9th February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
THOMAS YOUNG HALL, of the Town and County of Newcastle-upon-
Tyne, Coal Owner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of August, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reigu, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Young Hall, Her special
license that I, the said Thomas Young Hall, my executors, adminis-
trators, and assigns, or such others as I, the said Thomas Young Hall,
my executors, administrators, or assigus, 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
"IMPROVEMENTS IN COMBINING GLASS WITH OTHER MATERIALS," upon the
condition (amongst others) that I, the said Thonias Young Hall, by
an instrument in writing under my hand and seal, should particularly
lescribe 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 Thonias Young Hall, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and s
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to say:
My said Invention relates to a system or mode of increasing the
durability of glass without interfering to any great extent with its
transparency, and consists in the combination with glass, either on the
surface or internally, of metal, transparent or partially transparent, such
as wire gauze, perforated copper, platina, talc, &c., for the purpose of
increasing the durability of the glass without materially interfering with
its transparency. This may be effected by fusing such metals or other
materials with the glass, or by imbedding the other materials in the
glass when in a plastic state, or in any other convenient method. A
sheet of wire gauze, perforated copper, or other metal may be laid
between two plates of glass, giving great stability to the same, and
rendering it applicable to various useful purposes, such as the fronts of
fire grates, lamp chimneys and shades, and vessels and utensils of
various kinds, as well as for illuminating purposes, when the glass is
subjected to rough usage, as the deck-light of a ship's cabin, for example.
Figure 1, on the accompanying Sheet of Drawings represents in plan
the system or mode of strengthening glass by the application of wire
gauze, &c. Figure 2, is an edge view of the glass shewing the gauze,
which is colored red on the surface. A, A, represents the gauze, and
B, the glass. Figure 3, is a side elevation of a lanıp glass or cylinder
combined with wire gauze to be used in the construction of safety
lamps, as described in my Patent, dated the Ninth day of August One
thousand eight hundred and fifty-three. And Figure 4, is a plan of the
cylinder. In this case the gauze is inserted within the glass instead of
on the external surface only. In the manufacture of glass articles
combined with wire gauze, or any of the other strengthening materials
herein-before mentioned, it is necessary in cases where such articles
are required to be transparent that the air be exhausted from the
moulds during the insertion of the wire gauze or other material, or, in
other words, that the operation be effected in vacuo, otherwise the
oxygen of the atmosphere combining with the metal will turn the glass
black, rendering it perfectly opaque. The same principle is obviously

page_text: applicable to the ornamentation of glass. In such case the metal inserted
may be cut into various ornamental devices, such as flowers, scrolls, &c.
The above principle may also be employed for lettering plate glass for
windows, the letters being inserted during the casting of the glass, or
by placing them between two plates afterwards fused together, as
herein-before described. By previously silvering the metal or wire
gauze the effect will be greatly improved.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe, in conclusion, that I do not
confine or restrict myself to the precise details or arrangements which
I have had occasion to describe or refer to, as many variations may be
made therefrom without deviating from the principles or main features
of my said Invention; but what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in
part recited Letters Patent, is,-
The combination of any of the substances or metals herein-before
mentioned with glass in the manner and for the purposes herein-before
described.
In witness whereof, I, the said Thomas Young Hall, have here-
unto set my hand and seal, the Ninth day of February, One
thousand eight hundred and fifty-four.
THOS Y. HALL. (L.S.)
