IMPROVEMENTS IN THE MANUFACTURE OF IRON AND STEEL
Year: 1864

page_text: LETTERS. PATENT to Edwin Henry Newby, of Leicester, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF IRON AND STEEL."-A com-
munication from abroad by Anthony Leonard Fleury, residing at New
York, United States of America.
Sealed the 28th October 1864, and dated the 3rd May 1864.
PROVISIONAL SPECIFICATION left by the said Edwin Henry Newby at
the Office of the Commissioners of Patents, with his Petition on the
3rd May 1864.
I, EDWIN HENRY NEWBY, of Leicester, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF IRON AND STEEL," to be
as follows:-
This Invention has for its object improvements in the manufacture of iron
and steel, and consists in the utilization of waste cinder of puddling, reheating,
and steel furnaces, by introducing the same in a pulverized state into melted
iron in blast, cupola, or puddling furnaces by means of a blast, thereby
reducing the said cinders into cast iron, steel, or wrought iron. The cinders
can also be mixed with pulverized flux, such as lime, fluor spar, baryta, or
similar substances. The heat in the furnace is by these means materially
increased, the melting or puddling process is accelerated, and at the same
time the furnaces are made to yield a larger quantity of metal. By this
process I can, without impairing the quality of the iron or steel, reduce the
cinder and extract therefrom all the metal.

by the said Edwin Henry Newby in the Great Seal Patent Office on
the 2nd November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWIN
HENRY NEWBY, of Leicester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of May, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edwin Henry Newby, Her special licence. that I, the said Edwin Henry
Newby, my executors, administrators, and assigns, or such others as I, the said
Edwin Henry Newby, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVEMENTS IN
THE MANUFACTURE OF IRON AND STEEL," a communication to me from abroad by
Anthony Leonard Fleury, a person resident at New York, United States of
America, upon the condition (amongst others) that I, the said Edwin Henry
Newby, my executors or administrators, by an instrument in writing. under
iny, 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.
NOW KNOW YE, that I, the said Edwin Henry Newby, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in the manufacture of iron
and steel, and consists in the utilization of waste cinder of puddling, reheating,
and steel furnaces by introducing the same in a pulverized state into melted
iron. in blast, cupola, or puddling furnaces by means of a blast, thereby
reducing the said cinders into cast iron, steel, or wrought iron. The cinders
can also be mixed with pulverized flux, such as lime, fluor spar, baryta, or
similar substances. The heat in the furnace is by these means materially
increased, the melting or puddling process is accelerated, and at the same
time the furnaces are made to yield a larger quantity of metal. By this

page_text: process I can, without impairing the quality of the iron or steel, reduce the
cinder, and extract therefrom all the metal it contains.
In carrying out the Invention the waste cinder is reduced to a pulverized
state, and is introduced, either alone or mixed with a small per-centage of coal
dust and lime, into a box or hopper, or other receptacle connected with the
blast pipe, and fitted with a valve, so as to admit the pulverized cinder or
cinder and flux into the blast pipe in such manner that it will be carried by
the blast into the furnace, or, as in the instance of the puddling furnace, into
and among the molten iron; other flux than lime, as, for instance, fluor spar,
baryta, cryolite, may be used with the powdered cinder and injected in the
manner described. In this process the heat of the furnace is materially
increased by the oxygen of the cinder, the smelting, melting, or puddling
process accelerated, and at the same time the iron refined and made to yield
a larger per-centage of metal.
In witness whereof, I, the said Edward Henry Newby, have hereunto
set my hand and seal, this Twenty-ninth day of October, in the year of
our Lord One thousand eight hundred and sixty-four.
EDWIN H. NEWBY. (L.S.)
