page_text: JOHN LYNN Engineer 1 Howarth Street Sunderland WILLIAM TIMMS Com-
mercial Traveller 12 Pensbury Street Darlington do hereby declare the naturo
of our invention for IMPROVED PIPE, TUBE, STUD AND IRON ROD WEDGE GRIP
ATTACHMENT FOR ORDINARY SHIFTING OR FIXED SCREW KEYS AND SPANNERS to
be as follows:-
Engineers Plumbers Pipe and Tube manufacturers who are constantly using
Studs, Pipes, Tubes, and Iron of round section require handy appliances to firmly
and securely grip same wbile in the act of screwing or holding same into their
respective positions. A variety of clumsy and heavy tools being in use for that
purpose.
The object of our invention is to provide a simple and effective appliance by
which Pipes, Tubes, Studs, and Iron of round section may be securely held in
position or moved in alternate directions by aid of the ordinary Screw Key or
Spanner as shown in accompanying sketch. This appliance is in the taper form of
a wedge either slightly curved or straight on its inner surface and made of Steel,
Cast, Wrought, or Malleable Iron, but by preference Steel properly tempered to
resist the pressure brought to bear upon it and fitting between the inner surface
of Jaw of Screw Key or Spanner and the outer surface of Pipe, Tube or Iron of
round section. On the inside face of this Wedge Grip is cut a series of teeth or
serrations of an angular straight or curved form but by preference of an angular
form and cut either of a straight or spiral form across its face. These teeth or
serrations on wedge Grip come in contact with the outer surface of Pipe or Tube
and afford with the leverage of Screw Key or Spanner the necessary grip to move
same.
Or the Improved Wedge Grip may also be made with a cylinderical or other
projection on the back to fit into a drilled hole in the Jaw of Screw Key or
Spanner to retain it in.position.

mercial Traveller 12 Pensbury Street Darlington do hereby declare the nature
of our invention for IMPROVED PIPE, TUBE, ŠTUD AND IRON ROD WEDGE GRIP
ATTACHMENT and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-

Or the Improved Pipe Tube, Stud, and Iron rod Wedge Grip may also be made
with a cylinderical or other projection on the back to fit into drilled hole in the
Jaw of Screw Key or Spanner and thus retain it in. position.
Having now particularly described and ascertained the nature of our Inven-
tion and in what manner the same is to be performed we declare what we
claim is
1st The convenience by which the Improved Pipe, Tube, Stud and Iron rod
wedge Grip can be carried about being so small in size as to be conveniently a
carried in the waiscoat pocket.

converts same into a Pipe Wrench getting as firm a grip upon the Pipe or Tube as
the ordinary form of Pipe Wrenches commonly used.
3rd The Workman being able to carry it about with him without inconvenience
it is always at hand and ready for immediate use thus saving a lot of time it is
also exceedingly cheap compared with the ordinary forms of tools used for holding
and moving Pipes, Tubes &c.
