LETTERS PATENT to Samuel Goodby Senior of Wolverhampton in the County
of Stafford tool maker for an Invention of "IMPROVEMENTS IN TOOLS OR
APPARATUS FOR CUTTING AND FOR REDUCING TUBES AND FOR HOLDING AND
OPERATING TAPS USED FOR SCREWING TUBE SOCKETS AND OTHER PURPOSES
"
PROVISIONAL SPECIFICATION left by the said Samuel Goodby, Senior, at
the Office of the Commissioners of Patents on the 29th November 1882.
SAMUEL GOODBY, senior, of Wolverhampton in the County of Stafford, tool
maker, "IMPROVEMENTS IN TOOLS OR APPARATUS FOR CUTTING AND FOR
REDUCING TUBES, AND FOR HOLDING AND OPERATING TAPS USED FOR SCREWING
TUBE SOCKETS AND OTHER PURPOSES
"
The chief object of this invention is to construct the tools employed for the
purposes mentioned in the title so that they may be carried in and operated by
the ordinary stock used for screwing tackle, or in a stock similar thereto having an
adjusting screw, but this invention has also the further object of constructing
adjustable cutting tools for reducing the diameter of tubes, and adjustable tools
capable of fitting the heads of two or more sizes of screwing taps whereby to hold
and operate such taps.
I carry the ordinary rotary tube cutting tool in a block which is shaped at the
sides like an ordinary screwing die so as to fit within the stock. A block having
a V cut out of its face towards the cutting tool and its sides shaped as an ordinary
screwing die is placed also within the stock. To cut the tube it is of course placed
between the cutting tool and the V'd part, aforesaid, and the V'd block is screwed
up against the tube as in the ordinary way of tightening up the screwing dies, and
the stock is worked round by hand. The balanced pressure on each handle of the
stock produces an easier and more regular cut upon the tube. Both the blocks
used in cutting the tube may be removed if desired when the screwing dies are to
be employed, or the opening through the stock may be long enough to allow both
sets of tools to be kept in position together; or the V'd block may be removed and

page_text: the die nearest to the cutting tool be shaped on the back so as to receive the pro-
jecting part of the cutting tool and bed itself against the block. The cutting tool
may itself be carried within the metal of the stock instead of in a separate die.
The tools for reducing the diameter of tubes are shaped to fit within the stock,
aforesaid. One of the tools has a V-d face and the other a concave curved face.
The V-d face has cutting teeth running across it, and the curved face may have
corresponding teeth or may be quite plain. The curved face projects forwards
somewhat from its own block so as to be capable of entering within the V-d face
and thus accommodating itself to a small as well as to a large tube. The blocks
may be of any width across the face as may be required according to the width of
tube to be reduced. The tube is of course placed between the V-d and curved
faces to be reduced, and the stock is then worked round by hand and the pressure
put upon the reducing dies in the manner that it is put upon the screwing dies.
The teeth, aforesaid, cut down the metal of the tube and thus reduce its diameter
as the tools are turned round by means of the stock. These reducing dies may be
carried in the stock either separately or in conjunction with the dies required for
other operations.
The tools employed to hold and operate taps used for screwing tube sockets and
other purposes consist of two V'd blocks having their sides shaped so as to fit
within a screwing stock, and they may be carried in the stock either separately
or in conjunction with tools used for other operations. These tools are (as the
other tools) adjustable by means of the screwed handle of the stock, and may be
used for two or more sizes of tap.
The various tools, aforesaid, are preferably made interchangeable in one stock,
as described, thus saving considerably in weight and expense over the various
apparatus otherwise required; but a separate and similar stock may, if desired, be
used for one description of tools only, as before stated, thus forming either a tube
cutter, a tube reducer, or a tap wrench, as described.

by the said Samuel Goodby, Senior, in the Great Seal Patent Office on the
24th May 1883.
SAMUEL GOODBY senior, of Wolverhampton in the County of Stafford, tool
maker, "IMPROVEMENTS IN TOOLS OR APPARATUS FOR CUTTING AND FOR
REDUCING TUBES, AND FOR HOLDING AND OPERATING TAPS USED FOR SCREWING
TUBE SOCKETS AND OTHER PURPOSES.
"
The chief object of this invention is to construct tools to be employed for the
purposes mentioned in the title so that they may be carried in and operated by the
ordinary stock used for screwing tackle, or other similar stock having an adjusting
screw; but this invention has also the object of constructing adjustable cutting
tools for reducing the diameter of tubes, and adjustable tools capable of fitting the
heads of two or more sizes of screwing taps whereby to hold and operate such taps.
I carry the ordinary rotary tube cutting tool in a block which is shaped at the
sides like an ordinary screwing die so as to fit within the stock. A block, having
a V cut out of its face towards the cutting tool and its sides shaped as an ordinary
screwing die is placed also within the stock. To cut the tube it is of course placed
between the cutting tool and the V-d part, aforesaid, and the V-d block is screwed
up against the tube as in the ordinary way of tightening up the screwing dies, and
the stock is worked round by hand. The balanced pressure on each handle of the
stock produces an easier and more regular cut upon the tube than in the case of an
ordinary single-handled tube-cutter. Both the blocks used in cutting the tube
may be removed if desired when the screwing dies are to be employed, or the
opening through the stock may be long enough to allow both sets of tools to be
kept in position together; or the V-d block inay be removed and the die nearest
to the cutting tool be shaped on the back so as to receive the projecting part of the
cutting tool and bed itself against the block. The cutting tool may itself be
carried within the metal of the stock instead of in a separate block.
The tools for reducing the diameter of tubes are shaped to fit within the stock,
aforesaid. Each of these tools has a concave curved face with cutting teeth
running across it. The tube is of course placed between the curved faces to be
reduced and the stock is then worked round by hand and the pressure put upon
the reducing dies in the same manner that it is put upon the screwing dies. The
teeth, aforesaid, cut down the metal of the tube and thus reduce its diameter as the
tools are turned round by means of the stock. These reducing dies may be carried
in the stock either separately or in conjunction with the dies required for other
operations, or they may be carried in any suitable holder, their shape being
modified as may be necessary to fit therein.
The tools employed to bold and operate taps used for screwing tube sockets and
other purposes consist of two V-d blocks having their sides shaped so as to fit
within a screwing stock, and they may be carried in the stock either separately or
in conjunction with tools used for other operations. These tools are (as the other
tools) adjustable by means of the screwed handle of the stock, and may be used
for two or more sizes of tap.
The various tools, aforesaid, are preferably made interchangeable in one stock as
described, thus saving considerably in weight and expense over the various
apparatus otherwise required; but a separate and similar stock may, if desired, be
used for one description of tools only, thus forming either a tube cutter, a tube
reducer, or a tap wrench as described.
Having thus stated the nature of my said invention, I will now proceed more

page_text: particularly to describe and ascertain the manner of performing the same with
reference to the accompanying drawings, of which figure 1 is a view of the ordinary
description of screwing stock, with a pair of my tube cutting tools fitted therein.
Figure 2 is a corresponding view to figure 1, but shews the V'd cutting tool to be
replaced with a pair of ordinary screwing dies. Figure 3 is a longitudinal section
through the centre of figure 2. In each of these views parts of the stock are
shewn to be broken off for convenience of illustration. Figure 4 is an elevation of
a pair of reducing tools, and figure 5 an inside view of one of such tools. Figure 6
is an elevation of a pair of tools employed for the purposes of a tap wrench, figure 7
is an inside view of one of such tools, and figure 8 is a back view of the one of
such tools which is intended to be placed first within the stock. The same letters
of reference occurring upon different views indicate corresponding parts.
Referring to figure 1, A A is the stock, B the rotary cutting tool carried within
a block C, which latter is fitted within the stock in a similar manner to the
ordinary screwing dies, and D is the V'd block working in connection with the
rotary cutting tool and fitted also within the stock in the same manner as the
block C. E represents the section of a tube in position to be cut through by
the tools. The block D is tightened up by means of the ordinary screw F to put
on the cut. The rotary cutter B may, if desired, be carried direct within a recess
formed in the metal of the stock in which case the block C would be dispensed
with.
Referring to figures 2 and 3 A A is the stock, C the block carrying the rotary
cutter, and F the ordinary screw, as before. G and G' are ordinary screwing dies,
except that the die G! has a sunk or recessed part a at its back to receive the part
of the rotary cutter B which projects from the block C. It will be seen that to
change the apparatus illustrated by figure 1 from a tube cutter to a screwing
apparatus as illustrated by figures 2 and 3, it is necessary merely to remove the
block D and replace it by the dies G and G.
When a tube reducing apparatus is required, the tools illustrated by figures 4
and 5 are substituted for the dies G and G. Referring to figures 4 and 5, H and H¹
are the tools which correspond in their relative position to one another when
within the stock to the dies G and G respectively. The tool H' has a recess at its
back corresponding in shape and purpose to the recess a within the die G. The
tools H and H have a number of cutting teeth running across their inner faces
as shewn, and in order to cause the reducing tools to traverse along the tube
instead of simply reducing a narrow circumferential strip, a thread is formed a
part of the way through the tools as shewn at figure 5. The thread is deeper
at the side of the tools and gradually shallows out at about the middle of the
tools as shewn. The inner diameter of the thread corresponds to, and is therefor
in the same curved plane as, the inner faces of the cutting teeth; but the
tools H and H' are formed somewhat larger on the screwed side thereof than on
the plain side so as to leave the tube slightly tapered after reducing to facilitate
the making of a tight joint after the thread is run thereon. The cut is put on
by means of the screw F as in the case of the other tools. These tools may be
carried in any suitable holder, as before stated, their shape being modified as may
be necessary to fit therein, and such holder may be fixed, if desired, and the tube
be turned within the tools.
Referring to figures 6, 7 and 8, K and K' are tap-wrench tools corresponding in
their relative position to one another when within the stock to the dies G and G'
respectively. The tools K and K' are V'd so as to form when forced up together
the square hole L which is of a size to fit over the square on the smallest size of
tap for which the tools are required to be used. As the tools K and K¹ are moved
apart the V'd parts will of course take in a larger square between them and may
thus be used for different sizes of tap. A recess is formed in the back of the
tool K' corresponding in shape and purpose to the recess in the tool G¹ (figures 2
and 3)
Having now stated the nature of my said invention and particularly described

page_text: and ascertained the manner of performing the same, I wish it to be understood that
I do not limit myself to the exact details described and illustrated, as such may be
varied without departing from the nature of the invention; but I declare that
what I claim as my invention and desire to secure by the hereinbefore in-part-
recited Letters Patent, is:-
First: The combination of the tube cutting tools with an ordinary screwing or
other similar stock substantially as and for the purpose described and shewn.
Second-The adjustable reducing dies having cutting teeth across their faces, in
combination with an ordinary screwing or other similar stock or otherwise carried
by any suitable means, substantially as and for the purpose described and shewn.
Third-The adjustable tap-wrench tools in combination with an ordinary
screwing or other similar stock, substantially as and for the purpose described
and shewn.
Fourth-Forming a recess in the back of the reducing and tap-wrenching tools
which abut against the rotary tube cutter block (or against that part of the stock
which carries the rotary tube cutter in case a loose cutter block is not employed)
when such tools are placed within the stock, substantially as and for the purpose
described and shewn.
Fifth The general arrangement and combination of parts consisting of the
ordinary screwing stock or similar stock and the tools for cutting, reducing and
tap-wrenching, the whole forming in conjunction with the screwing dies a complete
apparatus, substantially as and for the purpose described and shewn.
In Witness whereof I the said Samuel Goodby senior have hereunto set
my hand and seal this twenty-third day of May in the year of our Lord
one thousand eight hundred and eighty three.
