AN IMPROVED TUBE CUTTER AND WRENCH
Year: 1872

page_text: LETTERS PATENT to William Eades and William Thomas Eades, of
Birmingham, in the County of Warwick, Machinists, for the
Invention of "AN IMPROVED TUBE CUTTER AND WRENCH."
PROVISIONAL SPECIFICATION left by the said William Eades and
William Thomas Eades at the Office of the Commissioners of
Patents, with their Petition, on the 19th July 1872.
.
We, WILLIAM EADES and WILLIAM THOMAS EADES, of Birmingham,
in the County of Warwick, Machinists, do hereby declare the nature of
the said Invention for "AN IMPROVED TUBE CUTTER AND WRENCH," to be as
follows, that is to say:
-
Our Invention refers to an improved combination of a tube cutter
and wrench to be used for either purpose, as required, by means of a
removeable and reversible jaw or lever containing a revolving cutting
roller as ordinarily employed; the removeable and reversible jaw or
lever works upon a pin or centre passing through it at one end, and.
'

page_text: through the main piece of the cutter or wrench. The main piece has a
shaped head cut out or grooved upon its inner surface for the purpose of
receiving the puckering of the metal of the tube during the cutting
operation. This provision is found to be a great advantage.
The removable and reversible jaw or lever is secured below the
shaped head, and is acted upon by an adjustable screw working and
bearing upon the back face of the cutter holder. This screw works
through a wormed arm or shoulder extending from the body part of the
main piece; the main piece is formed with the usual tail or handle part.
The jaw or lever is released from the main piece when required to be
used as a wrench, and is reversed, and again attached by its pin to the
main piece, so that the cutter roller will be towards the screw, and the
back face towards the shaped head.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Eades and William Thomas Eades in the
Great Seal Patent Office on the 18th January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
EADES and WILLIAM THOMAS EADES, of Birmingham, in the County
of Warwick, Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of July, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William Eades and William Thomas Eades,
Her special license that we, the said William Eades and William
Thomas Eades, our executors, administrators, and assigns, or such others
as we, the said William Eades, and William Thomas Eades, our
exccutors, 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 TUBE-CUTTER AND WRENCH," upon the condition (amongst others)
that we, the said William Eades and William Thomas Eades, our

page_text: executors or administrators, by an instrument in writing under our, 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 we, the said William Eades and William
Thomas Eades, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, that is to say :-
Our Invention refers to an improved combination of a tube cutter
and wrench to be used for either purpose, as required, by means of a
removeable and reversible jaw or lever containing a revolving cutting
roller as ordinarily employed; the removeable and reversible jaw or
lever works upon a pin or centre passing through it at one end, and
through the main piece of the cutter or wrench. The main piece has a
shaped head cut out or grooved upon its inner surface for the purpose of
receiving the puckering of the metal of the tube during the cutting
operation. This provision is found to be a great advantage.
The removeable and reversible jaw or lever is secured below the
shaped head, and is acted upon by an adjustable screw working and
bearing upon the back face of the cutter holder. This screw works
through a wormed arm or shoulder extending from the body part of the
main piece; the main piece is formed with the usual tail or handle part.
The jaw or lever is released from the main piece when required to be
used as a wrench, and is reversed, and again attached by its pin to the
main piece, so that the cutter roller will be towards the screw, and the
back face towards the shaped head.
We will now proceed to describe the nature of our Invention more
fully in detail by aid of the annexed Drawings, reference being had to
the letters and Figures marked thereupon.
Figure 1 is a front elevation, and Figure 2 a side clevation of our
improved combined tube cutter and wrench to be used for either
purposé, as required, by means of a removable and reversible jaw or
lever (a) containing a revolving cutter roller (6) as ordinarily employed.
The removable and reversible jaw or lever (a) works upon a pin or

page_text: centre (c) passing through it and the main piece (d) of the cutter or
wrench; the main piece (d) has a shaped head (d') cut out or grooved
upon its inner surface for the purpose of receiving the puckering of the
metal of the tube during the cutting operation, which provision is found
to be of great advantage. The jaw or lever (a) is secured below the
shaped head (d³), and is acted upon by an adjustable screw (e) and
handle e¹, the screw (e) bearing upon the back face of the cutter
holder or jaw (a), and working through a tapped and wormed arm or
shoulder (f) extending from the body part of the main piece (d).
Figures 1 and 2 illustrate the parts arranged to 'cut a tube (9) held
in place in the shaped head (d') by the impact of the cutter roller (6)
tightened up, as requisite, by means of the adjustable screw (e).
Figure 3 is a side elevation of the combined cutter and wrench
adapted for wrenching a tube, for which purpose the jaw or lever (a) is
released from the main piece by unscrewing the pin (c) and reversed, as
shewn, being then resecured to the main piece, the cutter roller (b)
being below and out of use (h). Figures 2 and 3 is a sliding gripper
or incline, having a serrated or roughened edge, and used for the
purpose of tightening up the tube in place, and to prevent it from
slipping the moveable gripper or incline (h) is capable of a sliding
movement sideways by means of slots cut in the side arms of the
gripper (h) working on the centre or pin (i) carrying the cutter
roller, so that as the tube is tightened up the gripper or wedge (h)
will move slightly for obtaining a firmer hold upon the tube; or, as
shown in the detached full size side elevation, Figure 4, and section
Figure 5, of the lever or jaw (a), we form the gripper or wedge (k)
to work upon the centre or pin (i) radially, the gripper or wedge (k)
being suitably curved, as also the side edges of the jaw or lever (a),

page_text: Secondly. We claim the employment of a gripper or incline in com-
bination with the jaw or lever (a) for use as a wrench, the gripper or
incline sliding laterally on the jaw or lever (a), as shewn in Figure 3, or
working on a segment as in Figures 4 and 5, and as herein described.
And, lastly. We claim the combination of the several parts for the
purposes and in manner as herein more fully set forth and specified.
In, witness whereof, we, the said William Eades and William
Thomas Eades, have hereunto set our hands and seals, this
Seventeenth day of January, in the year of Our Lord One
thousand eight hundred and seventy-three.
WILLIAM EADES.
