Year: 1858

page_text: LETTERS PATENT to John Courage, of Horsleydown, in the County of.
Surrey, Brewer, and Frederick Bennett, in the County of Flintshire,
Smelter, for the Invention of "IMPROVEMENTS IN FURNACES FOR REDUCING
AND SMELTING ORES, SCORIA, SLAG, AND WASTE."
PROVISIONAL SPECIFICATION left by the said John Courage and
Frederick Bennett at the Office of the Commissioners of Patents, with
their Petition, on the 13th November 1858.
We, JOHN COURAGE, of Horsleydown, in the County of Surrey, Brewer, and
FREDERICK BENNETT, of Holywell, in the County of Flintshire, Smelter, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN FURNACES FOR
REDUCING AND SMELTING ORES, SCORIA, SLAG, AND WASTE," to be as follows:-
The object of our Invention is to utilize the heat which is ordinarily allowed
to pass off into the atmosphere from the slag hearth or from the cupola
furnace employed in the reduction or smelting of ores, scoria, and slag, by
rendering it available for the reduction of the "waste."
Our Invention consists, first, in constructing, in connection with the hearth
or furnace aforesaid, a horizontal or nearly horizontal furnace or bed upon
which the waste is laid, and over which the products of combustion from the
hearth or furnace are conducted for the purpose of partially or wholly reducing
the said waste.
. Our Invention consists, secondly, in regulating the degree of heat applied
to the said waste by means of a supplementary fire or furnace constructed
with one or more of the improvements described in the Specification of a
Patent granted to the said John Courage, dated the 25th day of May 1858.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Courage and Frederick Bennett in the Great Seal
Patent Office on the 13th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Jonn
COURAGE, of Horsleydown, in the County of Surrey, Brewer, and FREDERICK
BENNETT, of Holywell, in the County of Flintshire, Smelter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said John Courage and Frederick Bennett, Her special licence
that we, the said John Courage and Frederick Bennett, our executors,
administrators, and assigns, or such others as we, the said John Courage
and Frederick Bennett, 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 "Iм-
PROVEMENTS IN FURNACES FOR REDUCING AND SMELTING ORES, SCORIA, SLAG,
AND WASTE," upon the condition (amongst others) that we, the said John
Courage and Frederick Bennett, or one of us, our executors or administrators,
by an instrument in writing under our, or their, or one of our or their 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Courage and Frederick Bennett,
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 thereof, that is to say:-.
The object of our Invention is to utilize the heat which is ordinarily allowed
to pass off into the atmosphere from the slag hearth or from the cupola
furnace employed in the reduction or smelting of ores, scoria, and slag, by
rendering it available for the reduction of the "waste" from ores.
Our Invention consists, first, in constructing, in connection with the hearth
or furnace aforesaid, a horizontal or nearly horizontal furnace or bed upon
which the waste is laid, and over which the products of combustion from the
hearth or furnace are conducted for the purpose of partially or wholly reducing
the said waste.

page_text: Our Invention consists, secondly, in regulating the degree of heat applied
to the said waste by means of a supplementary fire or furnace constructed
with one or more of the improvements described in the Specification of a
Patent granted to the said John Courage, dated the 25th day of May 1858.
In carrying the first part of our Invention into effect, we do not limit
ourselves to any particular method or methods of constructing or arranging
the hearth or furnace, and the additional furnace or bed, as the method of
constructing and arranging the same may be variously modified to suit the
particular form of slag hearth or cupola furnace to which our improvement
may be applied. Any one skilled in the reducing and smelting of metallic
ores will be able without further description to carry this part of our Invention
into effect.
In carrying the second part of our Invention into effect, the supplementary
fire or furnace constructed with one or more of the improvements described in
the Specification aforesaid, may be applied in any suitable position, the heat
generated in the same being admitted to the aforesaid additional furnace or
shut off from the same, at such times and in such degree as may be necessary,
in order to suitably regulate the quantity of heat applied to the waste.
And having now described the nature of the said Invention, and in what
manner the same may be performed, we declare that we claim,—
First, the employment in connection with a slag hearth or cupola furnace of
an additional furnace or bed upon which the "waste" from ores may be laid,
and over which the products of combustion from the said slag hearth or cupola
furnace may be conducted for the purpose of partially or wholly reducing the
said waste.
Secondly, the method of regulating the degree of heat applied to such
waste by means of a supplementary fire or furnace constructed with one or
more of the improvements described in the Specification of a Patent granted
to the said John Courage, dated the 25th day of May 1858.
In witness whereof, I, the said John Courage, have hereunto set my
hand and seal, this Thirteenth day of May, One thousand eight hundred
and fifty-nine.
JOHN COURAGE. (L.S.)
