IMPROVEMENTS IN THE MANUFACTURE OF IRON."
Year: 1874

page_text: LETTERS PATENT to Frederick Herbert Gossage, of Widnes, in the
County of Lancaster, Manufacturing Chemist, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF IRON."
PROVISIONAL SPECIFICATION left by the said Frederick Herbert
Gossage at the Office of the Commissioners of Patents, with his
Petition, on the 18th April 1874.
I, FREDERICK HERBERT GOSSAGE, of Widnes, in the County of Lan-
caster, Manufacturing Chemist, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF IRON," to be as
follows:-
The chief object of this Invendion is to utilize in the manufacture of.
iron the substance known to chemists as "purple ore," which substance
is the refuse from iron and coppery pyrites after the sulphur and copper.
have been extracted therefrom by well known processes.
To render the purple ore suitable for use in blast or other iron pro-
ducing furnaces it is necessary to convert it into solid blocks or pieces
before submitting it to the process of smelting. For this purpose I so

page_text: far dry the purple ore as to leave about 12 per of water in it, and
mould the same into balls or bricks with the aid of mechanical pressure.
The balls and bricks thus obtained I heat in kilns, keeping up the fire
until a semi-fusion of the balls or bricks or a strong cohesion of the
integrant parts is effected, and I thus obtain semi-fused masses or lumps
of suitable size for admission to the smelting furnace.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Herbert Gossage in the Great Scal
Patent Office on the 14th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
HERBERT GOSSAGE, of Widnes, in the County of Lancaster, Manu-
facturing Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of April, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Frederick Herbert Gossage,
Her special licence that I, the said Frederick Herbert Gossage, my
executors, administrators, and assigns, or such others as I, the said
Frederick Herbert Gossage, 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
lawfully might make, use, excrcise, 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 IRON,"
upon the condition (amongst others) that I, the said Frederick Herbert
Gossage, my executors or administrators, by an instrument in writing
under my, or their, or one of 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.

page_text: NOW KNOW YE, that I, the said Frederick Herbert Gossage, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say) :-
The chief object of this Invention is to utilize in the manufacture of
iron the substance known to chemists as "purple ore," which substance
is the refuse from iron and coppery pyrites after the sulphur and copper
have been extracted therefrom by well known processes.
I so
To render the purple ore suitable for use in blast or other iron pro-
ducing furnaces, it is necessary to convert it into solid blocks or pieces
before submitting it to the process of smelting. For this purpose
far dry the purple ore as to leave about twelve per cent. of water in it, and
I then mould the same into balls or bricks with the aid of mechanical
pressure, using by preference some two to three tons to the inch. The
balls and bricks thus obtained I heat in kilns keeping up the fire until a
semi-fusion of the balls or bricks or a strong cohesion of the integrant
parts is effected, which usually takes place in about sixty hours. By this
means I obtain semi-fused masses or lumps of suitable size for admission
to the smelting furnace.
In some cases I may add to the purple ore previous to moulding
a small per-centage of clay or lime or of the two materials in com-
bination.
Having now set forth the nature of my Invention of "Improvements
in the Manufacture of Iron," and explained the manner of carrying the
same into effect, I wish it to be understood that under the above in part
recited Letters Patent I claim the treatment of purple ore in the manner
and for the purpose above described.
In witness whereof, I, the said Frederick Herbert Gossage, have
