page_text: LETTERS PATENT to Ephraim Allcock Jones and John Allcock Jones,
both of Middlesborough, in the County of York, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF IRON AND STEEL."
of "IMPROVEMENTS IN THE MANUFACTURE OF IRON AND STEEL."
Scaled the 20th January 1874, and dated the 18th October 1873.
PROVISIONAL SPECIFICATION left by the said Ephraim Allcock Jones
and John Allcock Jones at the Office of the Commissioners of
Patents, with their Petition, on the 18th October 1873.
We, EPHRAIM ALLCOCK JONES and JOHN ALLCOCK JONES, both of
Middlesborough, in the County of York, do hereby declare the nature
of our said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF IRON AND
STEEL," to be as follows:-
This Invention has for its. object the improving the quality and
reducing the cost of converting pig iron or metal into malleable iron and
steel in rotary puddling furnaces, or in other furnaces in which puddling
is done by mechanical means.

page_text: In carrying out this Invention we partially reduce the pig iron or
metal in a cupola or any other furnace adapted for the purpose by the
use of oxides of iron, whether in the form of iron ore, puddling furnace
cinders, hammer slag, mill-tap cinders, and roll crudes, or, scale, and
also of scrap iron, or in the furnace which has been in use a number of
years and is known as the refinery furnace, in order to eliminate a
portion of the carbon, silicon, and phosphorous from the iron or metal,
and so rendering it easier of further conversion in a rotary or other
mechanical puddling furnace, and saving much time as well as "fettling"
and coal.
From the cupola or other furnace where the reducing is partially
done we take the iron in a molten state to a rotary puddling furnace or
to any furnace, whether rotary or not, in which puddling is done by any
of the well known mechanical means, and in such furnace we complete
the reduction to iron and steel.
We also effect a further saving in the cost of production by heating
the fettling to any point short of melting preparatory to its introduction
into the rotary or other mechanical puddling furnace. This may be
effected in a stove at the foot of the chimney or in the neck of the
furnace in order to utilize the waste heat, or in any other convenient
way.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ephraim Allcock Jones and John Allcock Jones in
the Great Seal Patent Office on the 18th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, EPHRAIM 2
ALLCOCK JONES and JOHN ALLCOCK JONES, both of Middlesborough, in
the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of October, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty- 3
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Ephraim Allcock Jones and John Allcock
Jones, Her special license, that we, the said Ephraim Allcock Jones and
John Allcock Jones, our executors, administrators, and assigns, or such

page_text: others as we, the said Ephraim Allcock Jones and John Allcock Jones,
our executors, administrators, or 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 “Im-
PROVEMENTS IN THE MANUFACTURE OF IRON AND STEEL," upon the condition
(amongst others) that we, the said Ephraim Allcock Jones and John
Allcock Jones, by an instrument in writing under our hands and
seals, or under the hand and seal of one of us, 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 Ephraim Allcock Jones and John
Allcock Jones, 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, that is to say:
-
This Invention has for its object the improving the quality and
reducing the cost of converting pig iron or metal into malleable iron
and steel in rotary puddling furnances, or in other furnaces in which
puddling is done by mechanical means.
In carrying out this Invention we partially reduce the pig iron or
metal in a cupola or any other furnace adapted for the purpose by the
use of oxides of iron, whether in the form of iron ore, puddling furnace
cinder, hammer slag, mill-tap cinder, and roll cinder, or scale, and also
of scrap iron, or in the furnace which has been in use a number of years,
and is known as the refinery furnace, in order to eliminate a portion of
the carbon, silicon, and phosphorus from the iron or metal, and so
rendering it easier of further conversion in a rotary or other mechanical
puddling furnace, and saving much time as well as "fettling" and
coal.
From the cupola or other furnace where the reducing is partially
done we take the iron in a molten state to a rotary puddling furnace, or
to any furnace whether rotary or not in which puddling is done by
mechanical means, and in such furnace we complete the reduction to
iron and steel.
done we take the iron in a molten state to a rotary puddling furnace, or
to any furnace whether rotary or not in which puddling is done by
mechanical means, and in such furnace we complete the reduction to
iron and steel.

page_text: We also effect a further saving in the cost of production by heating
the fettling to any point short of melting preparatory to its introduction
into the rotary or other mechanical puddling furnace. This may be
effected in a stove at the foot of the chimney or in the neck of the
furnace in order to utilize the waste heat, or in any other convenient
way.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that what we consider
to be novel and original, and therefore claim as the Invention secured
to us by the herein-before in part recited Letters Patent is,―
First. We do not claim the reduction of pig iron or metal in a cupola
or other furnace, such as a reverberatory furnace, by the use of oxides,
or in that known as the ordinary refinery furnace, as herein-before
described, which are processes known and understood; but we claim,
the combination of the partial reduction of pig iron or metal in a cupola
or other furnace, together with the further reduction in a rotary or
mechanical furnace, the iron or metal from such cupola or other furnace
being charged in a molten state into a rotary or other furnace where
puddling is done by mechanical means.
Second. The heating of the fettling to any point short of melting
before its introduction to the rotary or other mechanical puddling
