by the said William Armand Gilbee in the Great Seal Patent Office on
the 26th September 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ARMAND GILBEE, of No. 4, South Street, Finsbury, London, and 39, Rue de
l'Echiquier, Paris, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of March, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year, of Iler reign,

page_text: did, for Herself, Her heirs and successors, give and grant unto me, the said
William Armand Gilbee, Her special license that I, the said William Armand
Gilbee, my executors, administrators, and assigns, or such others as I, the said
William Armand Gilbee, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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
THE MANUFACTURE OF GLASS," communicated to me by Monsieur Salmon, of
Paris, upon the condition (amongst others) that I, the said William Armand
Gilbee, by an instrument in writing under my hand and seal, should par-
ticularly 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 William Armand Gilbec, 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, reference being had to the Drawing hereto annexed
and to the figures and letters marked thereon, that is to say:-
The Invention, communicated to me, relates to improvements upon a
Patent obtained by me the Fourth day of September, One thousand eight
hundred and fifty-five, and consists in certain new arrangements of apparatus
for employing the heat and gas of coke ovens in the manufacture of glass.
DESCRIPTION OF THE DRAWING.
A, A, Figure 1, represent coke ovens; K, K, walls for separating each of
the coke ovens; F, F, are crucibles, placed in the melting furnace for melting
the glass; L, L, flues for the flame egressing from the pipe between the
crucibles, in order to beat them equally; J, pipe conducting the gas to the.
melting oven.
:
Figure 2 shews an oven of an oval form, for the same purpose as shewn at
Figure 1, the crucibles being of a cylindrical form. A, A, are coke ovens ;
K, K, walls for separating the ovens; E, oval pipe receiving the flame
produced in the coke ovens by the combustion of coal; and this pipe also
receives the gases from the gasometer, Figure 5; F, F, crucibles; J, pipe for
conducting the gas to the melting oven.
Figure 3, A, A, coke furnaces; K, K, walls; F, F, crucibles; M, M, vent
holes for the direction of the flame against each crucible, in order to secure an

page_text: equal heating; N, N, are the vent holes opposite cach crucible, through which
the flame passes to the crucibles; J, pipe conducting the gas to the melting
oven.
Figure 4, baking oven. A is a coke furnace, set between two glass re-
heating chambers B; C, C, vent holes at the upper part of the coke furnaces,
for manufacturing gas applied for lighting purposes, and also for melting glass;
D, D, upright pipes for conducting gas into the tar barrel E; F, pipe for
conducting gas to the gasometer. The purifiers and condensers are the same
as those generally employed.
Figure 5 shews the gasometer G; H is the reservoir; F, pipe for the
entrance of gas; J, egress pipe communicating with the melting furnaces;
the arrows shew the direction of the gas.
Figure 6 is a section of the coke ovens, and external view of the glass ovens.
A, A, ovens; B, B, vent holes communicating with the ovens, and allowing
the flame passing from one to the other to unite in the middle coke oven and
enter the pipe E; C, C, vent holes passing under the ovens, to assist the dis-
engagement of volatile matters in the coal; D, D, holes for feeding the ovens;
O, O, melting ovens, in which the crucibles are placed, as shewn in Figures 1
2, and 3; I, I, openings; L, L, chimneys for the flame. One or more of the
coke ovens may be suppressed; according to the quantity of gas required. The
ovens may be worked with open or closed crucibles, according to the color or
quality to be given to the glass.
And having now described the nature of the Invention communicated to me,
I wish it to be understood that I do not claim the various forms of ovens
herein described; but what I claim is, the arrangements of apparatus for the
employment of the waste heat of gas and coke ovens for the manufacture of
glass, as herein-before described, and referred to in the annexed Sheet of
Drawings.
In witness whereof, I, the said William Armand Gilbee, have hereunto
set my hand and scal, this Twenty-sixth day of September, in the year
of our Lord One thousand eight hundred and fifty-six.
