This invention relates to improvements in wire fencing. The invention consists
in the employment of one length of wire between each pair of straining posts that
is to say, the one end of the length of wire is attached to the winder or ratchet
of the centre straining post: it is led therefrom over a pulley wheel or roller at
the level at which the lowest wire is required. The same wire is then led to a pair
of pulley wheels at the opposite or side straining posts, the distance of the two
wheels apart regulating the distance of the lowest wire from the next wire. The
wire from the top roller of the side post is then led back to a pair of rollers on
the centre straining ratchetpost; then back to another pair of pulley
wheels on the side post; the distance of all the other pulley wheels apart, regulat-
ing the distance of the other wires apart.
The free end of the wire at the finish of the said backwards and forwards laying
of the wire, is secured to the same winder or ratchet as secures the other end, the
arrangement being such that on the rotating of the ratchet the wires are so
wound upon the ratchet drum that when the wires are strained in opposite directions
so that the whole wire of each section that is to say between post and post is
simultaneously strained by the one ratchet.
The same straining ratchet post holds the ratchet for the section of fencing at
its other side, that is to say, that the straining of two sections of fencing is effected
from the one or centre straining ratchet post.
The invention may be subject to various modifications, for example, two sec-
tions of fencing, with straining post in the centre, may have the two top wires
of both sections strained by the one ratchet on the centre straining post and the
same with regard to the two lower wires. Both sections of the fence may have
a single barbed wire at the top strained by means of a ratchet on the centre strain-
ing post.
Or two sections of the fence may have all the wires strained by a single ratchet
say a ratchet at the top of the centre straining post, in which case the ends of
the wires are secured to a fixed point towards the bottom of the end of the side
straining posts.
This arrangement of fencing may also have the top of the fence provided with
a barbed wire, strained from a ratchet on the centre straining post.
In order to support the two end straining posts that is to say the posts at either
side of the centre straining post, 1 provide each of them with a stay the one end of
which is fixed in the ground at an angle, with the other or top end against the
top portion of the straining post. The straining posts are preferably made of
lengths of har doubled. The stays are also preferably made of two bais rivetted
together at a distance apart corresponding with the width of the double bar of
the straining post; a notch being cut in the side of the bars of the posts to receive

page_text: the ends of the stay bar.
And in order to effect a firm attachment of the ends of
the said stays to the post, I provide the ends of the stay bars with a filling piece
which is rivitted between the two bars of the stay which filling piece fits within
the space between the two bars or sides of the straining post.

Improvements in Wire Fencing.
I, ANTHONY SIMPSON, Forester, of Bargany Mains, Dailly, Ayrshire, North
Britain, 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 improvements in wire fencing and has for its object to
equalise the strain on all the several wires constituting the fence, to bring a mutual
strain on all the bearing points and generally to simplify the construction of such
fences.
The method whereby the first named objects is attained consists in the employ-
ment of a single length of wire which extends alternately from one straining
post to the other and is subjected either to a single strain by securing one end of
the retroactive wire and winding the other, or to a conjunctive strain by winding
both ends together. Or three straining posts may be employed with a single wire
similarly arranged between each of the side posts and the centre post, the said
wires being either each subjected to a single or conjunctire strain, from the centre
winding post or the two wires together subjected to two single strains from one
winder on the centre straining post.
But in order that my said invention may be more readily understood and easily
carried into effect I will preceed to describe the same with reference to the accom-
panying drawings in which
Fig. 1 is an elevation of a portion of a fence as constructed in accordance with
my invention.
Fig. 2 is an end view of one of the end straining posts shewn in said figure.
Figs. 3 and 4 are views similar to Fig. I shewing modified forms of fencing.
Fig. 5 is a side view of a modified form of pulley mounting and
Figs. 6, 7, and 8 are detail views hereinafter more particularly referred to.
Fig. 1 of the said drawings illustrates a portion of a fence having a centre
straining post A and two side posts A². The wire B constituting the left hand
portion of the fencing has the one end attached to the winder (', is passed round
à pulley and led to the side post where it again passes over a pair of
pulleys D', whose distance apart determines the space between the lowest and
econd lowest wires. The wire then returns to the centre post A, passes over an-
other pair of pulleys D2 and back to the side straining past, the said backwards
and forwards laying of the wire being performed as often as found necessary,
the distance between each wire being determined in cach case by the space be-
tween the pulleys. The ice end of the wire B passes over the single pulley Fand
i secured to the winder or ratchet ('before referred to in such a manner that all
the wires of the fence are subjected to a conjunctive train when the ends are
wound upon the ratchet drum. The wite B on the right hand side of the fenc
is strained in the same way.

page_text: Or as a modification I may, as shewn in Fig. 3 attach the ends of the two
lengths of wire at F, F and after passing it around pulleys as before, connect
the ends of each wire to a single winder or ratchet G, the wires being rendered
taut by two single strains.
Also as a further modification in place of employing a single length of wire
for forming the complete fencing between each pair of straining posts I may
employ two, three or more wires, arranged as shewn in Fig. 4, a winder or ratchet G
being employed for each wire.
In order to support the two end straining posts A' A², I provide each of them
with a stay H composed of two bars of suitable metal rivetted together but held
apart by distance pieces, to allow the wires to pass between same, the upper end
of the said stays entering recesses formed in the straining posts which are formed
doubled as shewn in end view Fig. 2; and in order that the attachment of the
stays to the posts may be firm and secure, I provide the end of the stay bars with
a filling or distance piece which is arranged to fit into the space between the
two bars or sides of the straining post.
The stays being thus self fixtures at the points where they join the straining
post, requiring neither bolts nor rivets, enable the fencing to be easily erected.
The winders or ratchets are preferably placed in the straining post or posts so
that with the revolution of the winder in straining the accumulation of the wire
on the winder will not lift or throw the wire out of its parallel, as would be the
case with the two lower ratchets G G shewn in Fig. 4.
To prevent all the wires slackening if a break should take place in the wire I
may employ a sheet iron or other metal plate or holdfast Figs. 6 and 7 stamped
or otherwise formed with a groove j. These plates have a hole in the centre of
the groove through which the wire passes, the arrangement being such that after
the wires have been correctly strained the plates are pressed hard back against
the straining posts, and a small iron or other metal wedge or pin J driven in,
thus firmly keying the plate or holdfast to the wire, as shewn in Fig. 1. The
raised portion forming the back of the groove occupies the space between the bars
of the straining post to prevent side movement.
The said plates or holdfasts may also be made with a slit 3, as shewn in Fig. 8.
to allow the holdfast to be placed in position after the fence has been erected and
the wires strained, the hole in this case being formed with shoulders J³ to give a
greater gripping surface to the wedge.
The foregoing serve as illustrations of how my invention may be carried into
effect but I desire it to be understood that I do not limit myself to the details
hereinbefore described as it is obvious that they may be varied without departing
from my invention, as for instance I may mount the pulleys in brackets such as
shewn in Fig. 5, the said brackets being arranged upon a plain upright post of
any suitable cross section and bound in position by the jam nut K or otherwise.
Neither do I limit myself to the number of wires or ratchets employed nor to
the number, material or dimensions of the posts and other fittings.
A wire cr a number of wires may also be strained round a corner post or posts,
by placing the pulleys horizontally, the action being equally effective whether
the adjacent sections of fencing are at an acute or obtuse angle with each other.
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:-
1. In wire fencing, the employment of one or more wires stretched alternately
from one to the other of each pair of straining posts and passing over pulleys, or
their equivalent, secured in said posts, whereby the wires can be subjected to a
single or conjunctive strain to ensure the tension of all the wires being equal,
substantially as hereinbefore described and shewn in the accompanying drawings.
2. The combination with straining posts carrying one or more wires as clainied
in Claim. 1, ot holdfasts J arranged upon the respective wires and keyed in position

page_text: against the straining posts by wedges or pins 1, whereby the effect of breakage
of any one wire is confined to itself, substantially in the manner as hereinbefore
described and shewn in the accompanying drawings.
3. The construction and method of attaching the stays to the straining posts in
wire fencing whereby the attachment can be effected without the aid of bolts
and such like, substantially as herein before described and shewn in the accom-
panying drawings.
