page_text: LETTERS PATENT to William Corbett, of Clayton, near Manchester, in
the County of Lancaster, and William Carmont, of the same Place, Iron
and Steel Manufacturers, for the Invention of "CERTAIN IMPROVEMENTS IN
THE CONSTRUCTION AND ARRANGEMENT OF FURNACES EMPLOYED IN THE MANU-
FACTURE OF IRON AND STEEL, AND FOR OTHER SIMILAR PURPOSES."
aled the 27th October 1859, and dated the 29th April 1859.
PROVISIONAL SPECIFICATION left by the said William Corbett and
William Carmont at the Office of the Commissioners of Patents, with
their Petition, on the 29th April 1859.
We, WILLIAM CORBETT, of Clayton, near Manchester, in the County of
Lancaster, and WILLIAM CARMONT, of the same Place, Iron and Steel Manu-
facturers, do hereby declare the nature of our said Invention for " CERTAIN
IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF FURNACES EMPLOYED
IN THE MANUFACTURE OF IRON AND STEEL, AND FOR OTHER SIMILAR PURPOSES," to be
as follows:-
Our improvements. consist, first, in the application, employment, or use of
a brickwork shield over the metal hearth for the prevention of all deleterious
contact, whether arising from the gases of combustion, or from solid matters,
as coke, &c. getting into the iron, &c., from the furnace.
Secondly, in the application, employment, or use of a diaphragm or partition
between two metal hearths, and both said hearths heated from one furnace for
greater convenience in the conversion of steel or iron.

page_text: And, thirdly, in the use of a hopper with "any well-known suitable" self-
acting arrangement of mechanism for the gradual supply of "physic," (which
is a common and well-known operation in the manufacture of iron) to the
furnace or furnaces in the conversion of metals.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Corbett and William Carmont in the Great Seal
Patent Office on the 29th October 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CORBETT, of Clayton, near Manchester, in the County of Lancaster, and
WILLIAM CARMONT, of the same Place, Iron and Steel Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of April, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Corbett and William Carmont, Her special licence that we,
the said William Corbett and William Carmont, our executors, adminis-
trators, and assigns, or such others as we, the said William Corbett and
William Carmont, our 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 "CERTAIN IMPROVE-
MENTS IN THE CONSTRUCTION AND ARRANGEMENT OF FURNACES EMPLOYED IN THE
MANUFACTURE OF IRON AND STEEL, AND FOR OTHER SIMILAR PURPOSES," upon the
condition, amongst others, that we, the said William Corbett and William
Carmont, by an instrument in writing under our hands and seals, 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 filed
in the Great Seal Patent Office within six calendar months next and im-
mediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said William Corbett and William Carmont;
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement and accompanying Drawings (that is to say):
Our improvements consist, first, in the application, employment, or use of

page_text: a brickwork shield over the metal hearth for the prevention of all deleterious
contact, whether arising from the gases of combustion or from solid matters,
as coke, &c., getting into the iron, &c. from the furnace.
Secondly, in the application, employment, or use of a diaphragm or partition
between two metal hearths, and both said hearths heated from one furnace for
greater convenience in the conversion of iron or steel.
And, thirdly, in the use of a hopper with self-acting arrangement of
mechanism for the gradual supply of "physic," (which is a common and well-
known operation in the manufacture of iron) to the furnace or furnaces in the
conversion of metals..
In order that the Invention may be better understood and explained in
detail, we have hereunto attached a Drawing shewing a sectional Diagram,
and simply for the purpose of clearly representing the shield seen at a, a, over
the metal hearth b, b, for the prevention of all deleterious contact, whether
arising from the gases of combustion or from solid matters getting or falling
into the iron from the furnace; which particular feature of novelty we desire
to claim as of our Invention, and whether used separately or in combination
with the other above-named improvements in the construction and arrangements
of furnaces employed in the manufacture of iron and steel, and for other similar
purposes.
In witness whereof, we, the said William Corbett and William Carmont,
have hereunto set our hands and seals, this Twenty-eighth day of
October, in the year of our Lord One thousand eight hundred and
fifty-nine.
WILLIAM CORBETT. (L.S.)
