Ax IMPROVED IMPLEMENT FOR CUTTING PIPES AND BARS OF METAL
Year: 1864

page_text: LETTERS PATENT to John Wolstenholme, of Ratcliffe, in the County of
Lancaster, Plumber, Glazier, and Gasfitter, for the Invention of "Ax
IMPROVED IMPLEMENT FOR CUTTING PIPES AND BARS OF METAL."
Sealed the 13th June 1865, and dated the 26th December 1864.
PROVISIONAL SPECIFICATION left by the said John Wolstenholme at
the Office of the Commissioners of Patents, with his Petition, on the
26th December 1864.
I, JOHN WOLSTENHOLME, of Ratcliffe, in the County of Lancaster, Plumber,
Glazier, and Gasfitter, do hereby declare the nature of the said Invention
for "AN IMPROVED IMPLEMENT FOR CUTTING PIPES AND BARS OF METAL," to be as
follows:-
My Invention consists in cutting pipes or bars of metal by means of a
circular cutter revolving in a bush which slides on a hooked piece of steel or
other metal. The pipe or bar to be cut is securely held in a vice or other-
wise, and the circumference of the cutter is brought against the pipe or bar
by means of a screw passing through the lower end of the hooked piece, above
referred to; the implement is then turned round by the handle forming the
continuation of the screw, and the cutter is set up by turning the screw. By
this means the cutter gradually penetrates into the metal until the pipe is
cut asunder, or the metal bar is sufficiently indented to enable it to be
broken.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WOLSTENHOLNE, of Ratcliffe, in the County of Lancaster, Plumber, Glazier,
and Gasfitter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of December, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Wolstenholme, Her special license that I, the said John
Wolstenholme, my executors, administrators, and assigns, or such others as
I, the said John Wolstenholme, 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 "AN
IMPROVED IMPLEMENT FOR CUTTING PIPES AND BARS OF METAL," upon the con-
dition (amongst others) that J, the said John Wolstenholme, 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 Wolstenholme, do hereby declare
the nature of my 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 (that is to say) :-
My Invention consists in cutting pipes or bars of metal by means of a
circular cutter revolving in a bush which slides on a hooked piece of steel or
other metal. The pipe or bar to be cut is securely held in a vice or other-
wise, and the circumference of the cutter is brought against the pipe or bar by
means of a screw passing through the lower end of the hooked piece above
referred to; the implement is then turned round by the handle forming the
continuation of the screw, and the cutter is set up by turning the screw.
By this means the cutter gradually penetrates into the metal until the pipe

page_text: is cut asunder, or the metal bar is sufficiently indented to enable it to be
broken.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Figure 1 is a front view, Figure 2 an edge view, and Figure 3 a plan, partly
in section, of my improved implement for cutting pipes and bars of metal;
the Drawing is made of the full size.
In Figure 1, a is a section of a pipe which is supposed to be partly cut
through, and is the hooked piece forming the upper part of the improved
implement; c is the cutter revolving in the bush d, which slides on the side
of the piece b, the lower end of which is screwed like a nut. In the lower part
of the bush d is a recess to receive the end of the handle e, the bush and
handle being connected by the pin f fitting in a circular groove in the end
of the handle, the upper part of which is screwed into the piece b.
The mode of operation is as follows:-The pipe or bar to be cut is securely
held in a vice, or otherwise, and the circumference of the cutter c is brought
against the circumference of the pipe or bar by turning the handle e; the
implement is then turned round and the cutter is gradually set up by turning
the handle e until the pipe is completely cut through, or until the cutter has
penetrated the bar to the required extent; the screw e is then turned back
to liberate the implement, and the bar in which the groove has been cut can
then be broken in two by a slight blow.
Figure 4 represents a modification of my Invention; in this case the circular
rotating cutter c is replaced by a stationary cutter fixed in the bush d.
Having thus described the nature of my Invention, and the manner of
performing the same, I declare that I claim the improved implement for
cutting pipes and bars of metal, as shewn and described, and particularly the
rotary cutter c.
In witness whereof, I, the said John Wolstenholme, have hereto set
my hand and seal, this Thirteenth day of June, One thousand eight
hundred and sixty-five.
JOHN WOLSTENHOLME. (L.S.)
