Year: 1858

page_text: LETTERS PATENT to John James Russell, of Wednesbury, in the County
of Stafford, Iron Tube Manufacturer, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR CUTTING AND SCREWING THE ENDS OF TUBES."
PROVISIONAL SPECIFICATION left by the said John James Russell at
the Office of the Commissioners of Patents, with his Petition, on the
4th August 1858.
I, JOHN JAMES RUSSELL, of Wednesbury, in the County of Stafford, Iron
Tube Manufacturer, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN MACHINERY FOR CUTTING AND SCREWING THE ENDS OF TUBES,"
to be as follows:-
This Invention has for its object improvements in machinery for cutting and
screwing the ends of tubes. For these purposes each tube is introduced into
and fixed in a hollow mandril, which receives rotatory and reversing motion
by suitable gearing. And in order that both ends of a tube may be acted on
without moving it from the mandril, there is on either side of the headstock
above described a bed or suitable guides, on each of which slides a suitable
sliding carriage, having a suitable cutter for cutting off a portion of the end of

page_text: a tube, and also a die or screw tool for cutting or forming a screw at the end of
the tube, these instruments being combined with the carriage in such manner
that when one has been moved out of the way, the other may come into a posi-
tion to act on the end of a tube. The end of the tube, when being cut, is
In
supported by a suitable bearing, consisting, by preference, of three rollers.
some cases, the carriage in place of having two sets of tools, is arranged with
only a cutter, or with a screwing tool or die. By these means, tubes may be
cut to the lengths desired, and screwed at the ends with great facility, and
without requiring to be moved from place to place between the processes of
cutting off the ends and making the screws.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John James Russell in the Great Seal Patent Office on
the 4th February 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JAMES RUSSELL, of Wednesbury, in the County of Stafford, Iron Tube
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of August, 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 me, the said
John James Russell, Her special licence that I, the said John James
Russell, my executors, administrators, and assigns, or such others as I, the said
John James Russell, 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 FOR CUTTING AND SCREWING THE ENDS OF TUBES," upon the condition
(amongst others) that I, the said John James Russell, 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 within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John James Russell, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in machinery for cutting
and screwing the ends of tubes. For these purposes each tube is introduced
into and fixed in a hollow mandril, which receives rotatory and reversing
motion by suitable gearing. And in order that both ends of a tube may be
acted on without moving it from the mandril, there is on either side of the
headstock above described a bed or suitable guides, on each of which slides a
suitable sliding carriage, having a suitable cutter for cutting off a portion of
the end of a tube, and also a die or screw tool for cutting or forming a screw
'at the end of the tube, these instruments being combined with the carriage in
such manner that when one has been moved out of the way the other may
come into a position to act on the end of a tube. The end of the tube, when
being cut, is supported by a suitable bearing, consisting, by preference, of three
rollers. In some cases, the carriage, in place of having two sets of tools, is
arranged with only a cutter or with a screwing tool or die. By these means
tubes may be cut to the lengths desired, and screwed at the ends with great
facility, and without requiring to be moved from place to place between the
processes of cutting off the ends and making the screws.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a plan of a machine combined according to my Invention;
Figure 2 is a side elevation; Figure 3 is a cross section, taken through the
line A, B; and Figure 4 is a cross section, taken through the line C, D.
a, a, a, is the frame of the machine, which is arranged to receive a sliding
carriage at each end, each of which carries suitable tools for cutting and screwing
the ends of tubes; b, b, is the hollow mandril driven by gearing; the gearing
is arranged to reverse by means of mitre wheels, as shown at c, or other
reversing gearing may be used; q, q, is the tube to be cut and screwed, which
is held in the hollow mandril by means of the screw clamps s, s; d, d, d, cylin-
drical bars to carry the moving carriages e, e;. the under side of each of the
front bars has a rack formed on it to receive the pinion f fixed on spindle g
worked by the hand wheel h to move the carriage a distance depending on
the length of tube. The apparatus for cutting and screwing being alike at
both ends of the machine, the description of that at one end will be sufficient.
jjj, are rollers, to receive the tube and hold it steady, but to allow it to
revolve until the ends are cut and finished; k, h, k, k, is a rest or tool holder

page_text: to hold the tool to cut the tubes; - is a slide fitted on the rest or tool holder
to carry the third or front roller j, as shown on the enlarged views at
Figures 5, 6, and 7 of the Drawings. When the tool is brought back by the
handle m, the slide and roller are carried back with it. When the tool
holder is moved forward, the roller is pressed against the pipe before the tool,
and is kept up to it; the cutting tool is allowed to proceed by the spiral
spring n in the slide 1, which allows sufficient movement to cut any pipe or
tube which may be put into the machine. When the cut has been made, the
tool is brought back, and by turning the hand wheel h the sliding carriage e
is brought forward towards the hollow mandril, to bring the screwing die o
into action; the screw die moves back on the spindle p, as shown, until the
tube is cut, then it is turned round to the end of the tube, and is held in
position by the spring catch t, and the tube is entered into the die o and
screwed, when the hollow mandril is reversed, to turn out the screw which has
been cut; the other end of the tube is entered into and screwed by the other
screw die, and when the mandril is reversed again a socket is screwed on the
first end, and the tube is complete. 7, 7, oil pan, to catch the oil running
from the dies while the pipe is being screwed.
Having thus described the nature of my said Invention, and the manner
of performing the same, I would have it understood that I make no claim to
any of the mechanical parts separately, nor do I confine myself to the details ;
but what I claim is, the combination herein described.
In witness whereof, I, the said John James Russell, have hereunto set
my hand and seal, this Fourth day of February, in the year of our
Lord One thousand eight hundred and fifty-nine.
Witness,
S. CARPMAEL.
