PROVISIONAL SPECIFICATION.
An Improved Apparatus for Straining Wire.
1, WALTER COLE, of 40, Colby Road, Gipsy Hill, in the county of Surrey,
Architect, do hereby declare the nature of this invention to be as follows:-
This invention relates to a novel and simple construction of apparatus for straining
fencing wire.
My improved apparatus is constructed of a lever, to the upper end of which is
pivoted a link, to one end of which is pivoted a hook; and to the other end an arm
provided with a self-adjusting gripper.
The said lever arm is also provided with a gripper.
By this arrangement, if it be desired to strain wires between two standards, the end
of one wire is formed into a loop which is passed over the said hook, and the other
wire is placed in the gripper of the arm pivoted to the said link, the end of the said
wire being brought to the gripper on the lever. By then moving the lever in the
direction in which the wire is to be strained, the said wire will be drawn through the
adjustable gripper, which allows it to pass in the direction in which the wire is to be
strained, but prevents it taking a backward motion.
In order to render the apparatus more portable, I sometimes dispense with the
lever with its gripper, in which case, to make use of the apparatus, an ordinary stick
or wooden handle is used, the end of which is adapted to pass through a hole or ring
with which provide the said arm carrying the adjustable gripper the end of the
handle or stick is passed into the said hole or ring, and the end of the wire to be
strained is twisted round the stick, and the said stick or handle then serves the same
purpose as the lever arm before mentioned.

COMPLETE SPECIFICATION.
An Improved Apparatus for Straining Wire.
I, WALTER COLE, of 40, Colby Road, Gipsy Hill, in the county of Surrey,
Architect, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
This invention relates to a novel and simple construction of apparatus for straining
fencing or other wires.
My improved apparatus is constructed of a lever to one end of which is jointed an
arm having a hook pivotted to one end, while the other end of the said arm is provided
with a self-adjusting gripper.
The said lever is also provided with a gripper.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing in which
Figure 1 is a plan view of my improved wire straining apparatus; and,
Figures 2 and 3 front and side views of the same respectively.
In the said figures a indicates the lever (hereinafter referred to as the operating
lever) and the arm jointed to the same at one end as at c, which arm is bifurcated,
as shewn in figures 2 and 3 in order to embrace the end of the operating lever. dis
the hook jointed to one end of the arm b, and e is the self-adjusting gripper at the
other end, which gripper comprises the grip-lever fand the projection g.

page_text: is the gripper on the operating lever, which gripper comprises a grip-lever i and
a stud or projection k.
Each of the grip-levers is provided with teeth on its gripping surface which, in
conjunction with the projections serve to firmly hold the wire. It will he noticed
that the teeth of the lever i are inclined partly in one direction and partly in the
opposite direction, the object of this arrangement being to enable the said lever to
grip on both sides for a purpose hereinafter described.
In conjunction with the grip-lever is arranged a spiral spring f' which serves to
maintain the gripping end of the said lever in contact with the wire.
The operation of the apparatus hereinbefore described is as follows:--Suppose it is
desired to strain two wires 1, m figure 1. and then connect them, the end of the wire lis
formed into a loop which is passed over the hook d, and the other wire m is placed in
the gripper e, the end of the said wire m being brought to the gripper h on the
operating lever a: if now the operating lever a is moved in the direction indicated
by the arrow figure 1, the wire m will be drawn through the adjustable gripper e,
which allows it to pass in the direction in which the wire is to be strained, but prevents
it from taking a backward motion. When the operating lever a has been moved to
its full extent it can be moved back to take anothor grip upon the wire which can
then be further strained and so on. When sufficient tension is obtained the free end
of the wire m can be passed through the loop of the wire l. In order to pull the wire
tight after passing it through the loop the end is again introduced into the gripper but
gripped by the opposite side of the lever i to that by which the wire was previously
held. By pulling the lever in the opposite direction to that indicated by the arrow
the wire m will be drawn tightly into the bight of the loop of the wire 7. when it can
be twisted to secure it. It is obvious that a wire can be strained up to a standard or
post by attaching the hook d to such post.
In order to render the apparatus more portable, I sometimes dispense with the
operating lever with its gripper in which case, to make use of the apparatus, an
ordinary stick or wooden handle is used, the end of which is adapted to pass through
a hole or ring n with which I advantageously provide the said arm & carrying the
adjustable gripper as shewn. The end of the wire m to be strained is then twisted
round the stick when it is introduced through the ring n, and the said stick or handle
then serves the same purpose as the operating lever before mentioned.
To enable a wire to be readily cut without the necessity for carrying separate shears,
I form a notch o in the handle a and I sharpen the edge of the adjacent part of the
lever h, so that, when the said lever is in the position indicated by the dotted lines a
wire can be placed in the notch o and be severed by moving the lever in the proper
direction.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1. In a wire-straining apparatus, the combination with an operating lever of an arm
provided at the ends with means for gripping or holding the wires to be strained, the
said operating lever also being provided with a wire-gripper, substantially as
described.
2. In a wire-straining apparatus, the employment of an arm provided with an eye
or ring to receive a rod or lever and having wire-gripping or holding devices at its
ends, substantially as described.
3. The manufacture and use of the improved wire-straining apparatus herein before
described and illustrated in the accompanying drawing.
