We THOMAS JONES of Netherton near Dudley in the County of Worcester
Tube Manufacturer and JAMES SMITH of N° 49 Himley Road Dudley aforesaid
Roll Turner do hereby declare the nature of the said Invention for
NEW OR
IMPROVED MACHINERY FOR THE MANUFACTURE OF WROUGHT IRON AND STEEL
TUBES to be as follows:-
"
Our invention consists of machinery the parts of which are constructed and
arranged in the manner hereinafter described for the manufacture of welded or
open and close jointed wrought iron and steel tubes.
The machine constituting our invention is situated during use immediately
opposite the furnace in which the skelps or strips of iron or steel from which the
tubes are made are heated. We will call that part of the machine which is
situated nearest the furnace the back of the machine and the part which is most
distant from the furnace we will call the front of the machine.
Our new or improved machinery is constructed essentially as follows.
In a strong vertical block or upright forming part of or fixed to the bed of the
machine an oblong horizontal passage or opening is made extending through the
said block. In the lower part of this passage is a die or tool having a trough like
figure and in the upper part of the said passage another die or tool is fixed the
space between the two dies or tools having in cross section the figure of the
letter U. These tools project a short distance from the front of the said block and
the upper tool passes into a cylindrical figure and terminates in an axial rod having
at its end a screw thread. The said terminal rod is of considerably less diameter
than the cylindrical part of the tool. The said rod has fitted on it a slightly
tapering hollow mandril which is fixed on the said rod by a screw nut taking onto
its screwed end. The end of the mandril of larger diameter is situated at the
front of the machine.. To prevent the possibility of the skelp twisting between
its emergence from the block carrying the tools and its reaching the end of the
mandril we fix a tongue on the top of the upper tool which tongue keeps the
edges of the skelp in position as the skelp passes to the mandril.
The parts of the tools described which project from the block or upright by
which they are supported are situated between a pair of rolls working one over
CD

page_text: the other in a vertical plane. The said rolls have grooves corresponding to the size
of the exterior of the tube to be made while the extreme end of the mandril has a
size corresponding to the interior of the tube to be made. The extreme end of the
mandril is situated in the eye of the rolls.
The action of the machinery is as follows:-The strip of sheet iron or steel to be
made into a tube is bent at its front end into a trough shape and is raised to a
welding heat in the furnace adjacent to the machine. The rolls of the machine
being made to rotate in the direction proper to draw the skelp through the
machine the end of the heated skelp is rapidly drawn from the furnace and passes
into the machine between the two tools described When the end of the skelp has
been passed so far into the machine that it is taken hold of by the rolls its further
progress is effected by the rolls. By the action of the rolls the edges of the
heated skelp are turned inwards and the skelp is drawn onto the mandril the
edges of the partially made tube are forcibly compressed between the rolls and
the mandril. The welding together of the edges of the tube is thereby effected
and the finished tube is delivered at the front of the machine.
Our machinery may be employed to manufacture welded iron and steel tubes
having either butt jump or lap joints. Our machinery may also be employed to
manufacture open and close jointed iron and steel tubes.

New or Improved Machinery for the Manufacture of Wrought
Iron and Steel Tubes.
We THOMAS JONES of Netherton near Dudley in the County of Worcester
Tube Manufacturer and JAMES SMITH of N° 49 Himley Road Dudley aforesaid
Roll Turner, do hereby declare the nature of our Invention for "NEW OR
IMPROVED MACHINERY FOR THE MANUFACTURE OF WROUGHT IRON AND STEEL
"
TUBES and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our invention consists of machinery the parts of which are constructed and
arranged in the manner hereinafter described for the manufacture of welded or
open and close jointed wrought iron and steel tubes.
The machine constituting our invention is situated during use immediately
opposite the furnace in which the skelps or strips of iron or steel from which the
tubes are made are heated. We will call that part of the machine which is situated
nearest the furnace the back of the machine and the part which is most distant
from the furnace we will call the front of the machine.
Our new or improved machinery is constructed essentially as follows:-In a
strong vertical block or upright forming part of or fixed to the framing of the
machine, an oblong horizontal passage or opening is made extending through the
said block. In the lower part of this passage is a die or tool having a trough like
figure and in the upper part of the said passage another die or tool is fixed the
space between the two dies or tools having in cross section the figure of the
letter U. These tools project a short distance from the front of the said block
and the upper tool passes into a cylindrical figure and terminates in an axial
rod having at its end a screw thread. The said terminal rod is of considerably less
diameter than the cylindrical part of the tool. The said rod has fitted on it a
slightly tapering hollow mandril which is fixed on the said rod by a screw nut
taking onto its screwed end. The end of the mandril of larger diameter is situated
at the front of the machine. To prevent the possibility of the skelp twisting
between its emergence from the block carrying the tools and its reaching the end
of the mandril, we fix a tongue on the top of the upper tool which tongue keeps
the edges of the skelp in position as the skelp passes to the mandril.
The parts of the tools described which project from the block or upright by
which they are supported are situated between a pair of rolls working one over
the other in a vertical plane. The said rolls have grooves corresponding to the size
of the exterior of the tube to be made while the extreme end of the mandril has a
size corresponding to the interior of the tube to be made. The extreme end of the
mandril is situated in the eye of the rolls.
Figure 1 of the accompanying Drawing represents in side elevation and
Figure 2 in front elevation machinery constructed according to our invention;
Figure 3 represents in side elevation and Figure 4 in end elevation the two tools
detached from the rolls; Figure 5 represents in end elevation and Figure 6 in
longitudinal vertical section the tools drawn to a larger scale than in Figures 3

page_text: and 4; Figure 7 represents a horizontal section of the tools, the said section
exhibiting the tapering and bell mouth form of the said tools.
The same letters of reference indicate the same parts in the several Figures of
the drawing.
a is a strong block fixed in front of the pair of rolls b, c in an oblong horizontal
passage or opening in which block, the tools d, e are supported. When the two
tools are fitted together they enclose a space having in cross section the form of the
letter U, the said space tapering from the front or.bell mouth to the opposite end
of the two tools as will be understood by an examination of Figures 5, 6 and 7.
Running along the middle of the two tools is a tongue e U shaped in cross section,
the shaped tongue e² passing into a cylindrical figure at and near its end e³.
The two tools project a short distance from the front of the. block a in which they
are supported in front of the rolls b, c. In the tongue e? of the tool e is a hole in
which an axial rod or screw bolt fis situated. On the inner end of the said rod f
is a taper mandril g the said mandril being fixed on the said rod by the screw
nut h. The mandril 9 is situated in the eye of the rolls a, b (see Figure 1) the
grooves in the said rolls corresponding in size to the exterior of the tube to be
made, while the extreme end of the mandril y has a size corresponding to the
interior of the tube to be made.
The action of the machinery is as follows:-
The strip of sheet iron, or steel to be made into a tube is bent at its front end
into a trough shape and is raised to a welding heat in the furnace adjacent to the
machine. The rolls b, c of the machine being made to rotate in the direction proper
to draw the skelp through the machine the end of the heated skelp is rapidly
drawn from the furnace and passes into the machine through the two tools d, e
the heated skelp or partially made tube as it emerges from between the said tools
having a figure the counterpart of that of the interior of the smaller end of the
tools. When the end of the skelp has been passed so far into the machine that it
is taken hold of by the rolls its further progress is effected by the rolls. By the
action of the rolls b, c the edges of the heated skelp are turned inwards and the
skelp is drawn onto the mandril g and the edges of the partially made tube are
forcibly compressed between the rolls and the mandril. The welding together of
the edges of the tube is thereby effected and the finished tube is delivered from
the machine.
Our machinery may be employed to manufacture welded iron and steel tubes
having either butt, jump or lap joints.
Our machinery may also be employed to manufacture open and close jointed
iron and steel tubes..
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that we
claim as our invention
The new or improved machinery for the manufacture of wrought iron and steel
tubes hereinbefore described and illustrated in the accompanying Drawing; that is
to say, the combination of the shaping or fashioning tools d, e, e², e³ and mandril g
used in conjunction with a pair of rolls substantially as described and illustrated.
