AN IMPROVEMENT IN THE MANU- FACTURE OF WELDED IRON TUBES
Year: 1858

page_text: LETTERS PATENT to Edwin Dixon, of Wolverhampton, in the County of
Stafford, Manufacturer, and John Fisher, of Wolverhampton aforesaid,
Tube Drawer, for the Invention of "AN IMPROVEMENT IN THE MANU-
FACTURE OF WELDED IRON TUBES."
PROVISIONAL SPECIFICATION left by the said Edwin Dixon and John
Fisher at the Office of the Commissioners of Patents, with their
Petition, on the 26th November 1858.
We, EDWIN DIXON, of Wolverhamption, in the County of Stafford, Manu-,
facturer, and JOHN FISHER, of Wolverhampton aforesaid, Tube Drawer, do
hereby declare the nature of the said Invention for "AN IMPROVEMENT IN
THE MANUFACTURE OF WELDED IRON TUBES," to be as follows:-
Our Invention consists of the use of two draw benches in the manufacture.
of welded iron tubes in place of one draw bench, as ordinarily employed. In.
the ordinary manufacture, the partially-formed tube is drawn from the furnace
in which it has been raised to a welding heat, and operated upon by a draw
bench situated opposite to the mouth of the furnace, the tube being operated
upon several times, and finished by the same draw bench.
In our improvement we place a second draw bench near, and by preference
parallel to the one situated opposite the mouth of the furnace, and after the
partially-made tube has been drawn through the ordinary draw bench, so as to

page_text: perfect its welding, we transfer it to the second draw bench, where the final
drawing is effected; by our improvement the manufacture of welded iron
tubes is expedited, and the tube improved by escaping unnecessary and exces-
sive heating, as, during the finishing of one tube at the second draw bench,
another tube may be in process of manufacture at the first draw bench.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edwin Dixon in the Great Seal Patent Office on the
20th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWIN
DIXON, of Wolverhampton, in the County of Stafford, Manufacturer, and
JOHN FISHER, of Wolverhampton aforesaid, Tube Drawer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of November, in the year of
our Lord One thousand eight hundred and fifty-eight, in the twenty-second
year of Her reign, did, for Herself, Her, heirs and successors, give and grant
unto us, the said Edwin Dixon and John Fisher, Her special licence that we,
the said Edwin Dixon and John Fisher, our executors, administrators, and
assigns, or such others as we, the said Edwin Dixon and John Fisher, 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, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVEMENT IN THE MANU-
FACTURE OF WELDED IRON TUBES," upon the condition (amongst others) that
we, the said Edwin Dixon and John Fisher, our executors or administrators,
by an instrument in writing under our or their hands and seals, or under
the hand and seal of one of us, or them, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
I was to be performed, and cause the same to be filed in the Great Seál
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 Dixon, on behalf of myself and
the said John Fisher, 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 :-
Our Invention consists of the use of two draw benches in the manufacture

page_text: of welded iron tubes in place of the one draw bench which is employed in the
ordinary manufacture of the said welded iron tubes.
In manufacturing welded iron tubes by the ordinary method, the partially-
formed tube is drawn from the furnace in which it has been raised to a
welding heat, and operated upon by a draw bench situated opposite to the mouth
of the furnace, the tube being operated upon several times, and finished by
the same draw bench.
In manufacturing welded iron tubes according to our Invention, we place a
second draw bench near, and by preference parallel to the one situated
opposite to the mouth of the furnace. After the partially made tube has been
drawn through one draw bench, so as to effect the welding of the joint of the
said tube, we transfer it to the second draw bench, by the operation of which
the final drawing and completion of the tube is effected.
By our Invention the manufacture of welded iron tubes is expedited, as
during the finishing of one tube at the second draw bench, another tube mny
be in process of manufacture at the first draw bench. As the furnace and
draw benches which we employ in carrying our Invention into effect exactly
resemble the furnaces and draw benches ordinarily employed in the manu-
facture of welded iron tubes, (our Invention consisting in the use of two of
the said draw benches in place of the one ordinarily employed), we do not think
it necessary to represent by Drawings, or further to describe the said furnace
and draw benches. We claim as our Invention the improvement in the
manufacture of welded iron tubes, herein-before described, that is to say,
manufacturing welded iron tubes by the use of two draw benches, the welding
of the partially-formed iron tube being effected as it is drawn from the furnace
by the operation of one of the said draw benches, and the finishing of the tube
being effected by the operation of the other of the said draw benches.
In witness whereof, I, the said Edwin Dixon, have hereunto set my
hand and seal, this Eighteenth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine.
Witness,
HENRY JONES.
EDWIN DIXON. (L.S.)
