CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF IRON
Year: 1864

page_text: LETTERS PATENT to. William Taylor, of Shiffnal, Ironmaster, Henry
Harrison, of Hollinswood, Manager, and George Brown, of Hollinswood,
aforesaid, Millwright, all in the County of Salop, for the Invention of
"CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF IRON."
Sealed the 13th April 1865, and dated the 19th October 1864.
PROVISIONAL SPECIFICATION left by the said William Taylor, Henry
Harrison, and George Brown at the Office of the Commissioners of
Patents, with their Petition, on the 19th October 1864.
We, WILLIAM TAYLOR, of Shiffnal, Ironmaster, HENRY HARRISON, of
Hollinswood, Manager, and GEORGE BROWN, of Hollinswood, aforesaid, Mill-
wright, all in the County of Salop, do hereby declare the nature of the said
Invention for "CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF IRON," to be
as follows:-
The first part of our Invention relates to an improved mode of working the
puddling furnace. We propose to introduce into the furnace during the
operation of puddling jets of cold air; this we do by means of suitable pipes

page_text: which are provided, the outer ends of which are on the outside of the-furnace,
and the inner ends being so placed that the jets of cold air come directly upon
the iron. Air is pumped through these pipes by means of a blast engine in
the usual manner, and as is well understood. There may be any convenient
number of pipes employed, but for an ordinary puddling furnace we find three
sufficient; these we prefer to introduce respectively through the bridge jamb,
the flue jamb, and through the back of the furnace; but we desire it to be
understood that we do not at all confine ourselves to these positions in placing
the pipes.
Secondly, in order to obtain greater purity of iron we propose by means of
the pipes described to force or inject a flux of any ordinary kind into or upon
the iron while it is being puddled. For this purpose a blast engine is also
employed. By use of the means described we are enabled to take the balls
from the puddling furnace at once to the lumping fires without the intervention
of either the forge hammer or forge rolls.
SPECIFICATION in pursuance of the conditions of 'the Letters Patent, filed
by the said William Taylor, Henry Harrison, and George Brown in the
"Great Seal Patent Office on the 19th April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
TAYLOR, of Shiffial, Ironmaster, HENRY HARRISON, of Hollinswood, Manager,
and GEORGE BROWN, of Hollinswood, aforesaid, Millwright, all in the County
of Salop, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant' unto us, the
said William Taylor, Henry Harrison, and George Brown, Her special licence
that we, the said William Taylor, Henry Harrison, and George Brown, our
executors, administrators, and assigns, or such others as we, the said William
Taylor, Henry Harrison, and. George Brown, our 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, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, he Channel Islands, and Isle of Man, an Inven-

page_text: ion for "CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF IRON," upon the
condition (amongst others) that we, the said William Taylor, Henry Harrison,
and George Brown, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said William Taylor, Henry Harrison, and
George Brown, do hereby declare the nature of the 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 first part of our Invention relates to an 'improved mode of working
the puddling furnace. We propose to introduce into the furnace during the
operation of puddling jets of cold air; this we do by means of suitable pipes
which are provided, the outer ends of which are on the outside of the furnace,
and the inner ends being so placed that the jets of cold air come directly upon
the iron. Air is pumped through these pipes by means of a blast engine in
the usual manner, and as is well understood. There may be any convenient
number of pipes employed; but for a ordinary puddling furnace we find three
sufficient; these we prefer to introduce respectively through the bridge jamb,
the flue jamb, and through the back of the furnace; but we desire it to be
understood that we do not at all confine ourselves to these positions in placing
the pipes.
Secondly, in order to obtain greater purity of iron, we propose by means of
the pipes described to force or inject a "flux" (which flux may be of the
ordinary kind) into or upon the iron while it is being puddled. For this
purpose a blast engine is also employed.
In our Provisional Specification we set forth that we thought we should
have been able to take the balls from the puddling furnace at once to the
lumping fires, without the intervention of either the forge hammer or forge
rolls; but we find upon further experiment that this cannot prudently
be done.
Having now described the nature of our Invention, and the manner in
which the same is or may be carried into effect, we desire it to be understood
that without limiting ourselves to the exact details herein-before described (as
these may be varied to some extent without departing from the nature of our
Invention), we claim,-

page_text: First, the mode or manner of injecting jets of cold air into or upon the
iron during the operation of puddling, as described.
Seccond, injecting a "flux" into or upon the iron; as described.
In witness whereof, we, the said William Taylor, Henry Harrison, and
George Brown, have hereunto set our hands and seals, this Eighteenth
day of April, in the year of our Lord One thousand eight hundred
and
