IMPROVEMENTS IN WATER TWYERS FOR BLAST FURNACES
Year: 1865

page_text: LETTERS PATENT to Nathaniel Neal Solly, of Moseley Hall, near Wolver-
hampton, in the County of Stafford, Ironmaster; for the Invention of
"IMPROVEMENTS IN WATER TWYERS FOR BLAST FURNACES."-Partly a com-
munication from abroad by Mr. Norris Best, of Woodstock, New Bruns-
wick, North America.
PROVISIONAL SPECIFICATION left by the said Nathaniel Neal Solly at
the Office of the Commissioners of Patents, with his Petition, on the
15th March 1865.
I, NATHANIEL NEAL SOLLY, of Moseley Hall, near Wolverhampton, in the
County of Stafford, Ironmaster, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN WATER TWYERS FOR BLAST FURNACES," to be
as follows:-
The twyer or tuyere at present in use is a hollow truncated cone of iron,
of which the sides are hollow to allow of the circulation of cold water through
them, and they are generally of wrought iron, but sometimes of cast iron, and
in the axis of the twyer lies the nose of the blast pipe, which is also of wrought
iron. I use in the manufacture of twyers either copper alone or copper
combined in suitable proportions with tin or zinc, or tin and zinc, or some
other alloy, and of this metal or combination of metals I form either the
entire twyer or a suitable portion of the nose end of it, being that part which
is most exposed to the action of the fire in the furnace.
The advantages of my Invention do not depend upon any exact proportion
of the metals above named being used; combinations in many different

page_text: proportions produce a successful result. Amongst others I have found a
mixture of 64 parts of copper and 7 parts of tin mixed perfectly well, also
this proportion of copper and tin with the addition of one-fourth of old brass
castings
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said Nathaniel Neal
Solly in the Great Seal Patent Office on the 29th September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHANIEL
NEAL SOLLY, of Moseley Hall, near Wolverhampton, in the County of Stafford,
Ironmaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Nathaniel Neal Solly, Her special licence that I, the said Nathaniel
Neal Solly, my executors, administrators, and assigns, or such others as
I, the said Nathaniel Neal Solly, my 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
máke, 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 WATER TWYERS FOR BLAST FURNACES," the result partly of a
communication from abroad made to me by Norris Best, of New Brunswick,
North America, and partly the result of my own Invention, upon the condition
(amongst others) that I, the said Nathaniel Neal Solly, my executors or
administrators, by an instrument in writing under my, 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 on or before the
Thirtieth day of September, One thousand eight hundred and sixty-five.
NOW KNOW YE, that I, the said Nathaniel Neal Solly, 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 thereof, that is to say:-
The twyer or tuyere at present in use is a hollow truncated cone of iron, of
which the sides are bollow to allow of the circulation of cold water through

page_text: them, and they are generally of wrought iron, but sometimes of cast iron, and
in the axis of the twyer lies the nose of the blast pipe, which is also of wrought
iron. I use in the manufacture of twyers either copper alone or copper
combined in suitable proportions with tin or zinc, or tin and zinc, or some
other alloy, and of this metal or combination of metals I form either the entire
twyer of the usual form as above described, or a suitable portion of the nose
end of it, being that part which is most exposed to the action of the fire in the
furnace, and which may be either joined to the iron portion of the twyer by
mechanical means, or the copper, either pure or alloyed, as above described,
may be run or melted over the outside of it. The twyer may, if preferred, be
formed of a conical coil of tubing made of copper, either pure or alloyed, as
above described.
The advantages of the Invention do not depend upon the exact form of the
twyer, or upon any exact proportion of the metals above named being used,
as combinations in many different proportions produce a successful result.
Amongst others I have found a mixture of 64 parts of copper and 7 parts of
tin succeed perfectly well, also this proportion of copper and tin with the
addition of of old brass castings. Besides the advantage of the improved
working of the blast furnace from the use of my twyers is that of safety from
leaky twyers, the danger of explosions being removed, as these twyers are not
liable to be cut off or injured at the nose if kept supplied with water, no iron
or other minerals ever becoming attached to them.
What I claim is,-
First, the employment of copper, either pure or alloyed, as above described,
in the formation of entire water twyers for blast furnaces of any shape
or form.
Secondly, the employment of copper, either pure or alloyed, as above
described, in the formation of the whole or the external part only of the nose
end of water twyers of any shape or form.
In witness whereof, I, the said Nathaniel Neal Solly, have hereunto set
my hand and seal, this Twenty-fifth day of September, in the year
of our Lord One thousand eight hundred and sixty-five.
NATHANIEL NEAL SOLLY. (L.S.)
