IMPROVEMENTS IN APPARATUS FOR SHAVING AND CUTTING METAL BARS AND METAL TUBING
Year: 1866

page_text: PROVISIONAL SPECIFICATION left. by the said John Wolstenholme and
John Tomlinson Pendlebury at the Office of the Commissioners of
Patents, with their Petition, on the 17th February 1866.
We, JOHN WOLSTENHOLME, of Radcliffe, in the County of Lancaster, and
JOHN TOMLINSON PENDLEBURY, of Elton, in the same County, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR SHAVING
AND CUTTING METAL BARS AND METAL TUBING," to be as follows:-.
The object of one of our improvements is to shave the outside of tubes,
such as gas pipes, to a size best adapted to the cutting thereon a thread or
screw, and thereby save the filing and re-screwing that so often takes place in
the ordinary process of gas fitting. Solid bars may also be acted upon in the
same way. Our apparatus is also adapted for cutting tubes or bars into
desired lengths, as will be hereafter shown.

page_text: For the purposes named we use a wrench having a slot in or near the
middle of its length, into which are placed two rollers within a short distance
of each other. A movable arm having a slot in it, and a regulating screw
attached which passes through a hole or slot situate in the said wrench with
a nut to vary the distance of the said arm from the said rollers is also
attached to the wrench by a pin or stud on which it moves.
The said arm
carries a tool box in which is placed the cutting and shaving tool, it also
carries an adjusting plate which has for its object the adjusting of the position
of the cutting or shaving tool with the curve of the metal to be shaved or
cut. Both the adjusting plate and the tool box are movable on a stud or pin,
and the adjusting plate is regulated relatively to the tool box by a common.
thumbscrew. The tube or bar to be cut or shaved is placed between the
said rollers and the cutting or shaving tool, and the depth of cut is regulated
by the before-named regulating screw attached to the said wrench.
We also place on the before-named arm a circular revolving cutter of the
same form and for the same purpose mentioned in the Specification of the
Patent granted to John Wolstenholme, No. 3213, and dated December 26th.
1864, by the use of which we are enabled to cut pipes and bars independent
of the other cutting tools before named. We dispense with the two rollers
before named when desirable, and allow the tube or bar to work in a hollow
portion of the said wrench when being cut or shaved.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Wolstenholme and John Tomlinson Pendlebury in
the Great Seal Patent Office on the 16th August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WOLSTENHOLME, of Radcliffe, in the County of Lancaster, and JOHN
TOMLINSON PENDLEBURY, of Elton, in the same County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of February, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said John Wolstenholme and John Tomlinson Pendlebury, Her
special licence that we, the said John Wolstenholme and John Tomlinson
Pendlebury, our executors, administrators, and assigns, or such others as we,
the said John Wolstenholme and John Tomlinson Pendlebury, our executors,
administrators, and assigns, should at any time agree with, and no others,

page_text: 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 SHAVING AND
CUTTING METAL BARS AND METAL TUBING," upon the condition (amongst others)
that we, the said John Wolstenholme and John Tomlinson Pendlebury, by
an instrument in writing under our hands and scals, or under the hand
and seal of one of us, 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 late of the said Letters
Patent.
NOW KNOW YE, that we, the said John Wolstenholme and John Tom-
linson Pendlebury, 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
Drawing (that is to say):
The object of one of our improvements is to shave the outside of tubes such
as gas pipes to a size best adapted to the cutting thereon a thread or screw,
and thereby save the filing and re-screwing that so often takes place in the
ordinary process of gas fitting. Solid bars may also be acted upon in the same
way. Our apparatus is also adapted for cutting tubes or bars into desired
lengths, as will be hereafter shown.
moves.
For the purposes named, we use a wrench a. Figs. 1, 2, and 3, in the
Drawing, having a slot in or near the middle of its length, as shown in
Figs. 1 and 3. into which slot are placed two rollers c, c₁. within a short
distance of each other. A movable arm d, having a slot in it. and a regulating
screw e attached, which passes through a hole or slot situate in the said
wrench a, with a nut to vary the distance of the said arm d from the said
rollers c, c₁, is also attached to the wrench a by a pin or stud g on which it
The said arm d carries a tool box h, in which is placed the cutting
and shaving tool i, Figs. 2, 3, and 4, the broad end of the tool being used for
shaving and the narrow one for cutting into lengths when required, it also
carries an adjusting plate k, which has for its object the adjusting of the
position of the cutting or shaving tool i with the curve of the metal to be
shaved or cut, as shown by the tube in the Drawing. Both the adjusting
plate and the tool box h are movable on a stud or pin m, and the adjusting
plate is regulated relatively to the tool box h by a common thumbscrew n.
The tube or bar to be cut or shaved is placed between the said rollers c, C₁,

page_text: and the cutting or shaving tool i, and the depth of cut is regulated by the
before-named regulating screw e attached to the said wrench a.
We also place on the before-named arm a circular revolving cutter o
which revolves on the stud m before named. This cutter is of the same form
and for the same purpose mentioned in the Specification of the Patent granted
to John Wolstenholme, No. 3213, and dated December 26th, 1864, by the
use of which we are enabled to cut pipes and bars independent of the other
cutting tool i before named, and this is accomplished by simply turning the
plate and the tool box out of the way of the metal to be cut, and bringing
the cutter o against the bar or tube, when by the action of the regulating
screw e and the turning round of the wrench a the tube or bar may be cut.
Metal shafting in mills, metal pillars. and metal pipes, whether made of
malleable or cast metal, may casily be cut by the apparatus herein described.
We dispense with the two rollers before-named when desirable, and allow the
tube or bar to work in a hollow portion of the said wrench a when being cut
or shaved.
Having now described the nature of our Invention, and the manner in
which the said Invention is to be performed, we wish it to be understood that
what we claim is, the apparatus for cutting and shaving metal tubes and bars,
and the combination of parts as herein described, and for the purpose herein
set forth.
In witness whereof, we, the said John Wolstenholme and John Tomlinson
Pendlebury, have hereunto set our hands and seals, this Fifteenth day
of August, in the year of our Lord One thousand eight hundred and
sixty-six.
