PROVISIONAL SPECIFICATION left by the said Edwin Dixon at the
Office of the Commissioners of Patents, with his Petition, on the 26th.
September 1862..
I, EDWIN DIXON, of Wolverhampton, in the County of Stafford, Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY AND FURNACES USED IN THE MANUFACTURE OF WELDED 'IRON
TUBES," to be as follows:-
My Invention relates to that method of manufacturing welded iron tubes
in which two tubes are simultaneously welded.
My improvement in machinery used in the manufacture of welded iron
tubes consists in the employment of a single or ordinary draw bench, that is,
a'draw bench of the kind cominonly employed in making tubes singly instead.
of using a double or compound draw bench. I employ on the said single
draw bench a wagon having two forceps, by which forceps the tubes being
welded are taken hold of and drawn-out of the welding furnace and through.

page_text: the pincers by which the welding is effected. By this improvement economy
of space is effected, and the operations of the workman are facilitated.
My improvement in furnaces used in the manufacture of welded iron tubes
consists in separating the welding furnace from the preparatory furnace
commonly called the back hole, and in which the skelps are heated previous
to their introduction into the welding furnace. In the ordinary method of
constructing these furnaces the preparatory and welding furnaces are com-
prised in one structure, and are consequently in close proximity, the said
furnaces usually opening into one stack or chimney. In constructing the said
furnaces, according to my Invention, the said furnaces are built separately,
and are wholly independent of each other.
Furnaces constructed according to my Invention are more convenient than
ordinary furnaces, and are productive of less discomfort to the workmen.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edwin Dixon in the Great Seal Patent Office on the 21st
March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWIN
DIXON, of Wolverhampton, in the County of Stafford, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of September, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Edwin Dixon, Her special licence that I, the said Edwin
Dixon, my executors, administrators, and assigns, or such others as I, the
said Edwin Dixon, '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 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
MACHINERY AND FURNACES USED IN THE MANUFACTURE OF WELDED IRON TUBES,"
upon the condition (amongst others) that I, the said Edwin Dixon, my
executors or administrators, by an instrament 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

page_text: within six calendar months next and immediately after the date of the said
'Letters Patent.
NOW KNOW YE, that I, the said Edwin Dixon, 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:
:
My Invention relates to that method of manufacturing welded iron tubes in
which two tubes are simultaneously welded.
My improvement in machinery used in the manufacture of welded iron
tubes consists in the employment of a single or ordinary draw bench, that is, a
draw bench of the kind commonly employed in making tubes singly, instead of
using a double or compound draw bench. I employ on the said single draw
bench a wagon having two forceps, by which forceps, the tubes being welded,
are taken hold of and drawn out of the welding furnace and through the
pincers, by which the welding is effected. By this improvement economy-of
space is effected, and the operations of the workman are facilitated.

My improvement in furnaces used in the manufacture of welded iron tubes
consists in separating the welding furnace from the preparatory-furnace; -
commonly called the back hole, and in which the skelps are heated previous
to their introduction into the welding furnace. In the ordinary method of
constructing these furnaces the preparatory and welding furnaces are com-
prised in one structure, and are consequently in close proximity, the said
furnaces usually opening into one stack or chimney..
In constructing the said furnaces according to my Invention, the said
furnaces are built separately, and wholly independent of each other.
Furnaces constructed according to my Invention are more convenient than
ordinary furnaces, and are productive of less discomfort to the workmen.
Having explained the nature of my Invention, I will proceed to describo
with reference to the accompanying Drawings the manner in which the same
is to be performed.
Figure 1 represents a plan of a portion of a draw bench and welding
furnace for the manufacture of two welded iron tubes simultaneously, con-
structed according to my Invention, the said Figure 1 representing two tubes
in the act of being welded; Figure 2 is an elevation of the said welding
furnace; and Figure 8 is a horizontal section of the same; Figure 4 repre-
sents a plan of a preparatory furnace constructed according to my Invention;
Figure 5 is an elevation of the same; and Figure 6 is a horizontal section of
The same letters indicate the same parts in the several Figures.
a is the single or ordinary draw bench, situated in front of the welding
the same.

page_text: furnace b, on which said draw bench a a wagon c works. The said wagon c
carries two forceps d, e, by which forceps the tubes f, g, to be welded are
taken hold of and drawn from the welding furnace and through the pincers.
The fixed jaws or parts of the two forceps d, e, are carried by the block,h,,and
the moveable jaws or parts of the said forceps are attached to the free ends of
the levers i, k; l, m, are the pincers, through which the tubes f, g, are drawn, and
by which the welding of the said tubes is effected. The tubes f; 9, as they are
drawn through the pincers l, m, are supported on the cross piece n, as repre-
sented. Each of the tubes f, g, is drawn from the welding furnace b, through
a hole in the sliding doors o, p. The wagon c is connected to and works on
the draw bench a in the ordinary manner, and the manufacture of two tubes
simultaneously by the use of my Invention, is conducted in the same way as
when a double or compound draw bench is used.
By constructing machinery in the manner represented in the Drawings for
the manufacture of two tubes simultaneously, that is, welding two tubes simul-
taneously by means of a single draw bench instead of a double or compound
draw bench, economy of space and motive power are effected, and there is less
wear and tear in the machinery. The operations of the workman are also
much facilitated.
The preparatory furnace, Figures 4, 5, and 6, consists of a furnace separate
from and independent of the welding furnace, Figures 1, 2, and 3, instead of
being a portion of the same structure as the welding furnace, as is usual. The
said preparatory furnace consists of a flue q, in which the skelps are placed,
and heated previously to their being transferred to the welding furnace, Figures
1, 2, and 3. r is the fire-place of the preparatory furnace, and s, s, are
chambers at the back thereof; in which chambers the coal is heated before it
is fed to the fire-grate. The flame and heated air from the fire-placer pass to
the flue q, and heat the skelps therein, and then pass to the chimney or stack.
The skelps, after having been heated in the preparatory furnace, Figures 4, 5,
and 6, are placed in the flue t of the welding furnace, Figures 1, 2, and 3.
The draw bench a is situated in front of and in a line with the said flue t, as
seen in Figure 1. is the fire-place of the welding furnace, the flame and
heated air from which pass to the flue t, and raise the skelps therein to a
welding heat, which said skelps are welded and made into tubes by being
drawn out of the said flue t, and through the pincers l, m, in front of the said
flue, as herein-before described. Parallel with the said flue t is a smaller flue
or take-up w, by which flue wa portion of the flame and heated air passed
into the flue t is directed across the said flue t, and the skelps at that part arc
raised to a somewhat higher temperature than at the other portions of the said

page_text: flue, as is well understood. The flame and heated air after passing along
the flues t, w, escape to the stack or chimney.
My improved machinery and furnaces may be used in conjunction with one
another, or they may be used separately.
Furnaces constructed in the manner represented in the Drawings are
more convenient than ordinary furnaces and are productive of less discomfort
to the workmen.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and represented, as the
same may be varied without departing from the nature of my Invention; but
I claim as my Invention,-
Firstly, the improvement in machinery to be used in the manufacture of
welded iron tubes, herein-before described and illustrated in Figure 1 of the
accompanying Drawings, that is to say, manufacturing two tubes simul-
taneously by the use of a single draw bench provided with a wagon having
two forceps or a double forceps, by which forceps the skelps or partially made
tubes-are-taken-hold-of-and drawn-from-the-welding-furnace-and-through-the
pincers by which the welding of the tubes is effected.
Secondly, the improvement in furnaces used in the manufacture of welded
iron tubes, herein-before described and represented in Figures 1, 2, 3, 4, 5,
and 6 of the accompanying Drawings, that is to say, making the preparatory
and welding furnaces separate from and independent of each other.
In witness whereof, I, the said Edwin Dixon, have hereunto set my hand
and seal, this Twentieth day of March, in the year of our Lord One
thousand eight hundred and sixty-three.
Witness,
SAMUEL DIXON.
