PROVISIONAL SPECIFICATION.
Improvements in Tongs, Pliers, and Pipe Cutters.
I GEORGE OTWAY of 96 Sandringham Buildings Charing Cross Road London
Engineer do hereby declare the nature of this invention to be as follows:--
The object of my invention is to provide tongs or pliers wherein the gripping
hiting or cutting portion is removable and capable of presenting several different
biting or toothed edges successively on being removed and turned and which said
tongs or pliers being specially adapted for holding pipes or bars may be made
available for cutting the same.
In carrying out my invention I attach to the long arm or lever of the tongs
carrying the curved jaw at or about the pivot on which works the shorter arm, a
housing cover or cap capable of retaining in position a loose rectangular and square
shaped bit or piece of metal, preferably steel, free to move forward and backward
therein and on the upper face of the arm, I cut out a portion of this upper surface
of the longer arm immediately under the cover or cap the termination of which cut
presenting a slightly raised block or stop beyond which the loose bit or piece cannot
travel.
The shorter or lower arm is pivotted to the longer arm near to the lower surface
of each and is preferably bifurcated so as to embrace the longer arm and when the
loose block is placed in position it is pushed and held firmly against the pipe or
rod by the jaw or forked end of the lower and shorter arm when the two arms are
pressed together.
The piece or block is prevented from falling out of the chamber provided for it by
means of a small screw or other device acting as a stop. It will be seen that when
the first biting edge of the bit or block is worn it can be taken out turned and
replaced at once thus presenting a fresh edgo until the whole of the eight biting edges
have been worn out.
In using my tongs as pipe cutters I provide a similar bit or block on one or more
sides of which I provide a cutting projection to act upon the pipe or rod and this may
be exchanged at will for the holding or biting piece or block before mentioned.
I may
if found desirable fix or attach my eight edged reversible bit or block to
ordinary tongs or pliers in any convenient manner instead of the same being slipped
loosely into a chamber as before described.
Dated this 27th day of June 1889.

COMPLETE SPECIFICATION.
Improvements in Tongs, Pliers, and Pipe Cutters.
I GEORGE OTWAY of 96 Sandringham Buildings Charing Cross Road in the
County of Middlesex Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The object of my invention is to provide tongs or pliers wherein the gripping biting
or cutting portion is removable and capable of presenting several different biting or
toothed edges successively, said tongs or pliers being specially adapted for holding
pipes or bars but may be so arranged as to be available for cutting the same.
Referring to the accompanying drawings and to the figures and letters of reference
marked thereon

page_text: Figure 1 is an elevation and part section of my improved tongs or pliers with a
part of the hereinafter described cap C removed.
Figure 2 is a plan of the improved tongs or pliers.
Figure 3 is a perspective view of the rectangular shaped "bit" or piece of
metal D.
Figure 4 is an elevation of a "bit" provided with a tooth, which I prefer to use for
cutting purposes.
In carrying out my said invention I attach to the longer arm or lever A of the
tongs carrying the curved jaw B a cover or cap C capable of retaining in position
a loose rectangular and preferably square shaped "bit or piece of metal D of steel
or other suitable material free to move backward and forward therein and on the
upper face of the arm, I cut out a portion of this upper surface of the longer
arm immediately under the cover or cap C, the termination of which cut out portion
presents a slightly raised block or stop a beyond which the loose bit or piece D cannot
travel.
The shorter or lower arm G is pivotted to the longer arm near to the lower surface
of each and is preferably bifurcated so as to embrace the longer arm, and when the
loose block or piece is placed in position and the two arms pressed together the
bit D is pushed and held against the pipe or rod H by means of a tooth or
serration E on each fork of the lower or shorter arm G. The bit or piece is
prevented from falling out of the chamber provided for it by means of a screw F or
other device.
It will be seen that the loose bit or piece by reason of its shape as shewn in
Figure 3 is capable of presenting eight biting or gripping edges so that when one
edge is worn out the "bit" can be taken out and turned so presenting a fresh
edge until the whole of the eight are worn out.
To remove the loose bit the screw F is removed and the arm G dropped when
the "bit" or piece can be easily taken out and turned.
In using my tongs as pipe or bar cutters the loose bit or piece is replaced by
one having a tooth or projection on one side thereof such as shewn in Figure 4.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
First In tongs or pliers for use in bolding gripping or cutting pipes or rods
the employment of a removable bit or piece such as D preferably of steel said bit
or piece being retained in a suitable chamber by means of a screw F or other
device and capable of being held tightly against a pipe or rod by the tooth E on
each of the forks of the lower arm G substantially as described and illustrated in
the accompanying drawings.
Second-The general arrangement and combination of parts constituting my
improved tongs or pliers substantially as described and illustrated in the accom-
panying drawings.
