Year: 1872

page_text: LETTERS PATENT to Edward Thomas Hughes, of the Firm of Hughes
and Son, Patent Agents, 123, Chancery Lane, London, for the
Invention of "IMPROVEMENTS IN FURNACES FOR PUDDLING, MELTING,
REHEATING, CEMENTING, AND FOR HEATING BOILERS."-A communication
from abroad by Lambert Bicheroux, of the Firm of Bicheroux and
Sons, of Duisberg, Prussia.
Sealed the 22nd November 1872, and dated the 25th May 1872.
COMPLETE SPECIFICATION filed by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 25th May 1872, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents,
123, Chancery Lane, London, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
FURNACES FOR PUDDLING, MELTING, REHEATING, CEMENTING, AND FOR HEATING
BOILERS," and have petitioned Her Majesty to grant unto me, my exe-

page_text: cutors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn Declaration that the same has been com-
municated to me from abroad by Lambert Bicheroux, of the Firm of
Bicheroux and Sons, of Duisberg, Prussia.
NOW KNOW YE, that I, the said Edward Thomas Hughes, do
hereby declare that the following Complete Specification, under my hand
and seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed in and by the following
statement, that is to say: -
The object of this Invention is to obtain in simple and economical
constructions of furnaces high degrees of temperature by the direct
combustion of gas mixed with cold or hot air, the gas being produced
in any suitable generator by the slow combustion of fuel, and the air
being drawn or forced by drawing or blowing machines.
The manner in which this Invention is to be performed will be clearly
understood by the following description thereof, reference being had to
the figures and letters on the accompanying two Sheets of Drawings, in
which Figure 1, Sheet 1, is a longitudinal section, and Figure 2 a
sectional plan of one of these improved furnaces adapted for the several
operations of puddling, melting, reheating, and cementing metals, and
heating water or other fluids; Figure 3 is a sectional plan through d, o,
d, c, Figure 1; Figure 4, a section of Figure 3 at the line g, h; Figure 5
is a front view of Figure 1; and Figure 6 a section of Figure 5 at the
line C, D; and Figures 1, 2, 3, 4, 5, and 6, Sheet 2, are similar views of
a modified arrangement of the furnace.
In the Figures on both Sheets a represents the generator in which the
fuel is slowly consumed by means of the air passing between the fire-
bars, and the gas which is evolved passes through the passage b to the
passage c, into which atmospheric air enters from openings d through
the cross passages, and it is at the part o where the mixture of the gas
and air takes place, by which carbonic acid is produced by the combustion
of the oxide of carbon.
The part e, into which the materials to be puddled, melted, heated, or
cemented are placed, is entirely filled by the flame of the ignited gas and
air, the intensity of the flame being capable of being made to any
required decree by the proper admixture of the ignited gas and air, and

page_text: Having now described the nature and particulars of the said Invention
and in what manner the same is to be performed, I desire it to be under-
stood that I claim, the improved gas furnaces without regenerators, as
shewn and described, in which it is possible to procure the greatest heat
by a complete combustion of the gases at the proper place, which is
effected by the right quantity of air conducted to and mixed with the
gases.
In witness whereof, I, the said Edward Thomas Hughes, have here-
