Year: 1872

page_text: LETTERS PATENT to Thomas Richardson, John William Richardson,
and Adam Spencer, all of West Hartlepool, in the County of
Durham, Ironmasters, for the Invention of "IMPROVEMENTS
REPINA OD PUDDLING IDAY AND STEEL. "
IN
PROVISIONAL SPECIFICATION left by the said Thomas Richardson,
John William Richardson, and Adam Spencer at the Office of the
Commissioners of Patents, with their Petition, on the 30th Novem-
ber 1872.
We, THOMAS RICHARDSON, JOHN WILLIAM RICHARDSON, and ADAM
SPENCER, all of West Hartlepool, in the County of Durham, Ironmasters,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN REFINING OR PUDDLING IRON AND STEEL," to be as follows:-
The Invention consists in mixing any suitable molten material, such
for instance, as an oxide of iron "best tap," "pottery mine,” “ purple
ore,'
," "hematite ore," and other substances containing oxygen in com-
bination with molten metal, whether iron or steel, or a mixture of iron
and steel, for the purpose of refining or puddling it.
The operation is to be effected in any convenient way, such, for
instance, as the tapping of two or more vessels containing the metal and

page_text: the oxide or other suitable material, and causing the molten liquids to
flow together and thus to become mixed, stirring or agitating them in
some cases to ensure a more perfect result. It is contemplated that the
materials so mixed should be treated in any approved puddling or
refining furnace, and preferably in one of our revolving furnaces, for
which we obtained Letters Patent on 8th July 1871, No. 1788.
In some cases we contemplate introducing the molten material into
the furnace before or during the treatment of the metal therein.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Richardson, John William Richardson,
and Adam Spencer, in the Great Seal Patent Office on the 27th
May 1873.

said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following
statement
The Invention consists in mixing any suitable molten material, such
for instance, as an oxide of iron, "best tap," "pottery mine," "purple
ore,"
," "hematite ore," and other substances containing oxygen in com-
bination with molten metal, whether iron or steel, or a mixture of iron
and steel, for the purpose of refining or puddling it.
The operation is to be effected in any convenient way, such, for
instance, as the tapping of two or more vessels containing the metal and
the oxide, or other suitable material, and causing the molten liquids to
flow together and thus to become mixed, stirring or agitating them in
some cases to ensure a more perfect result. It is contemplated that the
materials so mixed should be treated in any approved puddling or
refining furnace, and preferably in one of our revolving furnaces, for
which we obtained Letters Patent on 8th July 1871, No. 1788.
