A METHOD, INTIRELY NEW, OP MAKEING MALLEABLE IRON FROM PIG OB SOW METAL, COMMONLY CALLED CAST IRON, AND FROM SCULL AND CINDER IRON OR OTHER CAST METAL, WITH RAW COALS OR COAKS, WITHOUT CHARCOAL, AND WITHOUT GRANULATIONS, MIXTURE OF FLUXES, OR OTHER INFUSIONS

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WRIGHT, of the Parish of West Bromwich, in the County of Stafford, Iron
Master, and Co-partner with RICHARD JESSON, of the Parish of West Bromwich
and County of Stafford, Iron Master, send greeting.
WHEREAS I, the said John Wright, together with the said Richard Jesson,
did, by Petition to His present Majesty, humbly shew that we, the said John
Wright and Richard Jesson, had invented "A METHOD, INTIRELY NEW, OP
MAKEING MALLEABLE IRON FROM PIG OB SOW METAL, COMMONLY CALLED CAST IRON,
AND FROM SCULL AND CINDER IRON OR OTHER CAST METAL, WITH RAW COALS OR
COAKS, WITHOUT CHARCOAL, AND WITHOUT GRANULATIONS, MIXTURE OF FLUXES, OR
OTHER INFUSIONS," and therefore, as well as for other reasons contained in the
said Petition, did pray His said Majesty to grant unto us, the said John
Wright and Richard Jesson, our executors, administrators, and assigns, His
Royal Letters Patent for the sole use and benefit of the said Invention within
that part of Great Britain called England, Dominion of Wales, and Town of
Berwick-upon-Tweed, for the term of fourteen years years, to the prayer of
which Petition His said Majesty was most graciously pleased to condescend,
and Letters Patent agreeable thereto have accordingly passed the Great Seal.

page_text: NOW KNOW YE, that I, the said John Wright, in compliance with and
in performance of a proviso or condition contained in the said Letters Patent,
do hereby describe and ascertain the nature of our said Invention in manner
following, viz':-
First, we heat any kind of fused or cast iron, or scull or cinder iron, to a
sufficient degree in a finery, with a fire of raw pit coal, fossil coal, or coaks,
and with blast of bellows, without carcoal, and without any mixture of fluxes
or infusion whatsoever.
Secondly, the metal being thus heated and prepared, we take the same out
of the finery in lumps or masses while hot, and beat the same into plates under
a large flat stamp or hammer; which done, we break the said plates when cold
into small pieces under another round stamp or hammer calculated for that
purpose, in order thereby to reduce it into small particles, and seperate and
divide the dust and sulphureous matter which the metal may have contracted
from the coals or coaks with which the same shall have been heated in the
finery, to the end such sulphureous matter may be the better and more easily
extracted.
Thirdly, these pieces of metal thus broken small we totally cleanse of such
sulpherous matter as aforesaid, and other their impurities, by washing either
by hand or in a rolling barrell, which goes or is moved by a wheel turned by
water, horses, or men, which rolling barrell we were the Inventors of, and first
made use of for this purpose, nor hath a rolling barrell as yet been made use
of for this or any such like purpose-by any other person or persons whomsoever
than ourselves, as I know or believe.
I
Fourthly, when the metal is thus prepared and purged of its impurities: (if
the same appears to be of a proper temperior quality); we heat the same. to a
sufficient degree in a common, air furnace, in pots or otherwise, with a fire
made with raw pit coal, fossil coal, or coaks, and then beat the same intó bars
from a chafery in the common or ordinary way of making iron; but in case
when the metal so prepared as aforesaid; the same: appears to be: either red
short or coal short, we put it into earthen vessels or pots; and mix with and add
thereto a proper quantity of scrap iron or nutt iron, and in such vessels or pots
heat the same to a sufficient degree in a common air furnace, with a fire'made
of such materials as aforesaid, and then beat the same into bars from a chafery!
in manner before mentioned, which bars will be exceedingly good malleable
iron, and equal, if not superior in quality, to any iron made by any other pro
cess yet discovered.
And I, the said John Wright, do hereby aver and déclare that the above is
+

page_text: true, full, and perfect description of our said Invention, which I am fully
erswaded will be of great benefit to the publick.
In witness whereof, I, the said John Wright, have hereunto set my hand
and seal, the Second day of December, in the year of our Lord
One thousand seven hundred and seventy-three.
Sealed and delivered, being first duly
stampt, in the presence of
W* SADLER.
RICH CHATTOCK.
JOHN (LS.) WRIGHT.
AND BE IT REMEMBERED, that on the Second day of December, in
the year of our Lord 1773, the aforesaid John Wright came before our said
