Year: 1863

page_text: LETTERS PATENT to Thomas Critchley Barraclough, of Manchester, in
the County of Lancaster, Engineer, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR. CUTTING METALLIC TUBES OR PIPES, OR TUBES OR PIPES
COMPOSED OF OTHER INDURATE SUBSTANCES."-A communication from abroad
by George Henry Sanborn, of Boston, U. S. A.
Sealed the 10th July 1868, and dated the 15th January 1863.
PROVISIONAL SPECIFICATION left by the said Thomas Critchley Barra-
clough at the Office of the Commissioners of Patents, with his Petition,
on the 15th January 1863.
I, THOMAS CRITCHLEY BARRACLOUGH, of Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS FOR CUTTING METALLIC TUBES OR PIPES, OR
TUBES OR PIPES COMPOSED OF OTHER INDURATE SUBSTANCES," (a communication to
me from abroad by George Henry Sanborn, of Boston, U. S. A.) to be as
follows:-
The apparatus for cutting or dissevering pipes or tubes consists of two
metallic rods or legs, by preference made of malleable or other elastic
description of iron, and hinged together at one extremity, and so formed near
the hinge or joint as to receive the pipe to be cut at right angles to the
cutter employed. The cutter which is made of steel slides vertically through
one of the legs, and its cutting force or pressure may be adjusted by means
of a thumb screw above it. The pipe to be cut is placed in the hollow made
for its reception, and the cutter is tightened down upon the pipe, the two
opposite ends are then brought nearly together and secured by a link; if now
the pipe be held firmly in a vice, and, the apparatus turned several times
round.in a direction at right angles to the axis of the pipe, the cutter will

which the tube is made be very thick more pressure is to be applied to the
cutter by means of the screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Critchley Barraclough in the Great Seal Patent
Office on the 15th July 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
CRITCHLEY BARRACLOUGH, of Manchester, in the County of Lancaster, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Hér Letters
Patent, bearing date the Fifteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Critchley Barraclough, Her special license that I, the
said Thomas Critchley Barraclough, my executors, administrators, and assigns,
or such others as I, the said Thomas Critchley Barraclough, 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 APPARATUS FOR CUTTING
METALLIC TUBES OR PIPES, OR TUBES OR PIPES COMPOSED OF OTHER INDURATE
SUBSTANCES," and which has been communicated to me from abroad by George
Henry Sanborn, of Boston, in the United States of America, upon the condition
(amongst others) that I, the said Thomas Critchley Barraclough, 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 Thomas Critchley Barraclough, 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, and accompanying Drawings (that is to say):-
The apparatus for cutting or dissevering pipes or tubes consists of two

page_text: metallic jaws, by preference made of malleable or other elastic description
of cast iron or steel, and hinged together at one extremity and so formed near
the hinge or joint as to receive the pipe to be cut at right angles to the cutter
employed; to these jaws at the further end to the hinge two steel or wrought
iron rods are attached. The cutter which is made of steel slides vertically
through one of the jaws, and its cutting force or pressure may be adjusted by
means of a thumb screw above it. The pipe to be cut is placed in the hollow
made for its reception, the two opposite ends of the rods are then brought nearly
together and secured by a link, links, or other substitute, the jaws being thus
caused to hold the pipe, and the cutter is tightened thereupon. If now the
pipe be held firmly in a vice, and the apparatus turned several times round in a
direction at right angles to the axis of the pipe, the cutter will penetrate
the material and dissever the tube. If the metal or substance of which the
tube is made be very thick, more pressure is to be applied gradually to the
cutter by means of the screw until it is cut through.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made about full
size.
Fig. 1 represents a side view (shewn partly in section) of the apparatus
for cutting tubes shewn in the operation of severing a tube, and in which
a, a, are the jaws made of malleable cast iron or other metal, which are
hinged together at c, and to which are attached the rods b, b, made of steel
or other slightly flexible metal, and are retained in the position shewn by
means of the link d or other convenient means of attachment. The cutter e
is made of steel and slides in a slot in the upper jaw, and may be tightened
to any required pressure by means of the screw f, so as to cause the cutting
points to enter the tube g, which is held in a vice or otherwise fixed whilst
the apparatus is turned round, causing the cutter to enter and by continued
turning to sever one portion of the tube from the other as herein-before
described, set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said Thomas Critchley Barraclough, have
hereunto set my hand and seal, this Thirteenth day of July, in the
year of our Lord One thousand eight hundred and sixty-three.
THOMAS CRITCHLEY BARRACLOUGH. (L.S.)
