Sealed the 27th October 1858, and dated the 28th April 1853.
PROVISIONAL SPECIFICATION left by the said William Armand
Gilbee at the Office of the Commissioners of Patents, with his
Petition, on the 28th April 1853.
I, WILLIAM ARMAND GILBEE, of the English and Foreign Patent
Office, 4, South Street, Finsbury, London, and 39, Rue de l'Echiquier,
Paris, do hereby declare that the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR HEATING," to be as follows:-
The Invention consists in the construction of furnaces so as to obtain
a constant supply of air to the same, and thereby effect a more complete
combustion of the fuel and gases, and produce therefrom a larger
amount of available caloric.

leading from the main pipes d, d, into the opening e, e, in the top of
the furnace; ff, upper chamber for heating; g, position of the vessel to
be heated; h, h, brick work surrounding the furnace.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Armand Gilbee in the Great Seal
Patent Office, on the 28th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM ARMAND GILBEE, of the English and Foreign Patent Office,
4, South Street, Finsbury, London, and 39, Rue de l'Echiquier, Paris,
send greeting.
WHEREAS Her Most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of April, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said William Armand Gilbee, Her
special licence that I, the said William Armand Gilbec, 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 thereafter during the term therein expressed, should and law-
fully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an In-Inntion for "IMPROVEMENTS IN APPARATUS FOR HEATING," com-
municated to me from a foreigner residing abroad, upon the condition
(amongst others) that J, the said William Armand Gilbee, by an
instrument in writing under my hand and scal, 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

page_text: 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 Gilbee, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained 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 consists in an improved construction of furnace, for
the better consumption of the inflammable gases of fuel employed for
heating and obtaining therefrom a greater amount of available caloric
than hitherto. This furnace is applicable to heating steam boilers, and
for the fusion of metals.
I will now proceed to describe the Drawing which represents the
peculiar construction of this furnace. In each of the figures the saine
letters of reference indicate similar parts.
Figure 1, is a front elevation of the furnace.
Figure 2, a vertical section through C, D, of Figure 1.
Figure 3, a horizontal section through A, B, of Figure 1.
Figure 4, longitudinal section through C, D, of Figure 1.
Figure 2, shows the vault or chamber above the fire grate. This
vault has a narrow opening D, which serves for the introduction of
streams of atmospheric air or water to the flame. The small openings
over the grate B, are made for the purpose of conveying air sideways to
the flame. E, E, are main pipes disposed on the sides of the opening D,
communicating with smaller pipes F, F, by which atmospheric air or
streams of water are conveyed to the flame through the opening D, to
animate the fire. The water by passing through the hot pipes has
its temperature raised, and reaches the flame in a warm state. The
mouths of the pipes E, and of the ash pit A, below the grate B, arc
provided with doors K, and I, for regulating the ingress of air
according to the different kinds of fuel employed, and the requisitions of
combustion. G, represents the position of the boiler H, to be beated.
And having now described the nature of the said Invention, and the
manner of carrying the same into execution, I wish it to be understood

page_text: that what I claim as of the said Invention, and intended to be protected
by the said in part recited Letters Patent, is,―
The method of constructing furnaces for obtaining and regulating the
supply of air to the fire, according to the requirements of combustion,
as herein-before described and referred to in the different figures of the
Drawing.
In witness whereof, I, the said William Armand Gilbee, have hereto
set my hand and seal, this Twenty-eighth day of October, in
the year of our Lord One thousand eight hundred and fifty-
three
