A NEW OR IMPROVED COMBINATION TOOL FOR USE BY GAS FITTERS AND OTHERS
Year: 1884

I GEORGE PLUMPTON of the Albion Works Warrington in the County of
Lancaster, Tool and File Manufacturer do hereby declare the nature of my said
Invention for "A NEW OR IMPROVED COMBINATION TOOL FOR USE BY GAS
FITTERS AND OTHERS," to be as follows:-
The object of this Invention is the construction of a combination tool for use
by gas fitters and others and which shall serve as what are known in the trade as
gas and cutting pliars as screw drivers and pipe openers and by the addition of
my improvements as a screwing plate or stock pipe cutters rhymers and screw tap..
In carrying out my Invention and as applied to a pair of ordinary gas pliars
I insert a solid screw die between the handles of the pliars as near the point of
the pliars as possible. For this purpose I widen out the handles somewhat and
form two square holes one in each of the said handles into which take two
corresponding projections formed on the sides of the die so that the closing of the
handles holds the die firmly in its place whilst the pliars form a convenient handle.
for using the die in screwing.
By removing the die the squared holes formed in the handles as above described
enable me to insert a rhymer or screw tap having a corresponding square shank
and thus I obtain a powerful rhyming or tapping tool. The dies rhymers and
screw taps may be of various sizes and be enclosed in a neat box and when thus
used form with the gas pliars a universal tool for the before mentioned purposes.
A guide plate may be attached to the solid die by screws when desired. According
to another modification of my Invention and to obtain an adjustable die and also
a pipe cutter I form one of the handles with a sharp bend at its lower end and
extend it to take into a hole formed in the other handle. I thus obtain a stock
into which I fix the ordinary screwing dies and adjust them by means of a screw
passing through the bent portion of the handle before mentioned-when used as a
pipe cutter I remove the screw dies and insert suitable cutting dies.

page_text: I GEORGE PLUMPTON of the Albion Works Warrington in the County of
Lancaster Tool and File Manufacturer do hereby declare the nature of my
Invention for A NEW OR IMPROVED COMBINATION. TOOL FOR USE BY GAS
FITTERS AND OTHERS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this Invention is the construction of a combination tool for use by
gas fitters and others and which shall serve as what are known in the trade as gas
and cutting pliars, as screw driver and pipe opener and by the addition of my
improvement as a screw plate or stock pipe cutter rhymer and screw tap.
In order that this my said Invention may be the more readily understood and
carried into practical effect I have hereunto annexed a Drawing illustrative of my
improvements and will now proceed to describe the same with the assistance of
the letters of reference marked thereon. Fig. 1 represents a front view and Fig. 2
a side view of a pair of ordinary gas pliars or tongs with my improvements applied
thereto and so forming a combination tool as aforesaid. Fig. 3 is a front view of
another pair of gas pliars or tongs shewing a modification of my improvements
applied thereto and Fig. 4 is a front view and Fig. 5 a side sectional view of the
same pair of pliars or tongs as illustrated in Fig. 3 but with the screw die.
substituted by cutting dies.
In carrying out my Invention as illustrated by Figs. 1 and 2 I widen out the
handles of the ordinary gas pliars so as to accommodate the insertion of a solid
screwing die "6" between such handles and as near the joint "c" of the pliars
as possible, this screwing die which is shewn separately in Fig. 2 is provided with
a pair of square projections "d" which take into corresponding square holes "e"
formed in the handles "a" and thus when such handles are closed the die "b" is
held firmly in its place between them and the pliars are. rendered useful for
screwing purposes.
In this solid die "b" the first part of the hole "61" is exactly bored out to the
diameter of the pipe to be screwed and thus forms a guide and ensures the true
starting of the screw thread upon the pipe or other article being operated upon.
By removing the screwing die "6" one of the square holes "e
may be utilized
for the ordinary square "f" on the shank of a screwing tap (see Fig. "2b") or of a
similar square upon a rhymer and thus I obtain a powerful tapping and rhymering
tool.
The screwing dies screwing taps and rhymers may be of various sizes and may
be enclosed in a neat box and when thus arranged constitute with the gas pliars a
universal or combination tool for the above mentioned purposes.
In the modification represented by Figs. 3, 4 and 5 I similarly widen out the
bandles "a" but form V slides or projections "g" upon the inside of such handles
and between which I mount the ordinary screwing dies "h" and I exercise the
necessary pressure upon such dies by the set screw "i" screwed through the
removable cross bar "j" seen separately in Fig. 6. The ends of this cross bar pass
through square holes "k" formed in the handles and which ends become locked in
position in their respective handles by the slots "/" in each bar permitting the
same to slide backwards in the holes "k as indicated in Figs. 3 and 4.
"
"
In Figs. 4 and the substituting of the cutting dies ". m for the screwing
dies "h" is sufficiently obvious without further explanation.
In Fig. 6 I represent a front view of a paring die to be used in conjunction with
the revolving cutting die " M the paring tool "n" in this die being designed to.
"

page_text: remove the burr as it is formed upon the pipe by the forcing up of the circular
cutter "m." The tool "n" is adjustable in this die by simply turning the milled
nut "o" which is screwed upon the shank of the said tool.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is:
1st The combination of the screw die with projections fitting into corresponding
holes formed in the widened out handles of gas pliars or tongs substantially as
and for the purpose berein before described and illustrated on the accompanying
Drawing.
2nd The combination of screwing dies or cutting dies and adjusting screw
passing through a removable cross bar applied to the handles of gas pliars or tongs
substantially as and for the purpose hereinbefore described and illustrated on the
accompanying Drawing.
