Improvements in and relating to Wire Fencing.
1, JOHN BROWN EVANS of Mabus, Cape of Good Hope South Africa (Farmer) do
hereby declare the nature of this invention to be as follows:-
My improvement is more particularly based on Letters Patent No. 12966 granted to
me A.D. 1885, 28th Oct. and consists in laying part of the fence wires in a trench.
underneath the ordinary upright fence or as part of the special fence, the principal
details of which are as follows. The standards are in section the shape of the letter U
but with the addition of four ribs of metal at the ends and the base of the letter.
The staple or other means to fasten up the horizontal wires are shaped like the
letter U-but with the top ends bent over in order to pass into the standard or
I also
suspender holes, and have a locking wiro or pin inserted into the second bend.
insert the staple nearly through the standard or suspender holes far enough to allow
the wings of the second bend to open out being composed of steel or a suitable
springing material for that purpose. To prevent the wires cutting when the standard
is used at an angle or as a terminal, I insert a bridge in it and for securing the
standard onto the wires I use a horizontal wedge. Part of the improvement relates
to the double eccentric clip in which I use only one side of the frame passing the
fence wires to be clipped in from the side instead of the ends as in my patent 1296685
and also forming the bed in which the wires rest into a curve or hollow, with lips to
prevent the wires coming out at the side.
I have found it necessary to equalize the expansion and contraction by means of a
spiral spring-using the same device on the ground straining machine, in order to
indicate the exact tension throughout the line of wire.

Improvements in and relating to Wire Fencing.
I, EDGAR HOWELL REX EVANS of 36 Oxford Street in the County of Middlesex,
Gentleman, Executor of John Brown Evans of Mabus, Cape of Good Hope South
Africa, Farmer deceased, 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 :-
In the specification of a former invention for which Letters Patent No. 12966
dated 28 Oct. 1885 were granted to John Brown Evans there are described a novel
type of and method of orecting wire fences and various improved apparatus and
appliances for use in connection with such erection and with the straining and fixing
of the wires. The improvements which form the subject of the present invention have
reference more particularly to the said former invention and comprise an improved
construction of fence standards; novel forms of staple for fastening the wires to the
standards and suspenders; a device hereinafter called a bridge for use in connection
with a standard to prevent the wires getting cut when the standard is used as a
terminal or at an angle, and an improved construction of double excentric clip for
securing two wires at the meeting or crossing points.
According to the present invention the standards are made of U shape in section
but with the addition of 4 ribs at the ends and base of the letter for the purpose of
strengthening the same. Fig. 1 of the annexed drawings represents one of these
improved standards in section; Figs. 2 and 3 are respectively a front view and a

page_text: 1
side view (partly in section) of the same on a smaller scale. a is the body
standard; bb are the ribs at tho ends of the U and c c the ribs at the base. d d are
the holes through which the staples hereinafter described are inserted; these holes
are made so as to come between the two ribs c c. Instead of these ribs c c the base of
the U may be rolled thicker than the other parts as seen in the section Fig. 4 this
having the same effect of strengthening the standards where they are liable to be
somewhat weak owing to the holes d d.
Figs. 5 and 6 represent one of the improved forms of staple for fastening the wires
to the standards or to the suspenders; this staple is seen in position at fin Fig. 4
and also in Fig. 3. It is in the form of the letter U but as the ends bent over as
represented at g; these bent over parts form hooks which when the staple has been
inserted into the holes d d of the standard (or into similar holes of a suspender)
receive a locking wire or pin h Figs. 3 and 4. ii represent the horizontal fence
wires which are fastened by the staples fand the locking wire h. Figs. 7 and 8
represent another improved form of staple which is also seen in position in Fig. 1.
It resembles in some respects the staple shown in Figs. 5 and 6 but it is a spring
staplo and is inserted through the holes of the standard from the front, being first
compressed as seen in Fig. 9 to allow it to pass through the hole; it is then allowed
to open out to its normal form as seen in Figs. 1 and 8 when its bent over ends
engage with the ribs c c of the standard.
The top wire of the fence is preferably further secured by a horizontal wedge k as
shown at Figs. 10 and 11.
Fig. 2 shows the staples applied to a suspender; the suspender is preferably a
plate of flat flexible steel with holes to receive the staples.
Figs. 12 and 13 represent the bridge hercinbefore referred to for preventing the
wires getting cut when the standard is used as a terminal or at an angle; the wire i
in this case passes through the hole of the standard a. The bridge which is marked j
is shaped to fit over the lower edge of the hole as shown and its upper surface is
grooved for the wire to lie in.
Figs. 14 and 15 represent the improved double excentric clip. It is composed of a
one sided frame 7 with a bed m for the two wires to rest in, this bed having a lip or
flange n to prevent the wires coming out at the side. p q are the 2 excentrics having
their axis on the bolt r which holds them to the frame. It will be seen that as the
frame has only one side the wires i i that have to be clipped can be passed in sideways
instead of having to be inserted endwise as with the double excentric clips described
in Specification No. 12,966 of 1885 already referred to. To enable the two clips p q
to be affixed to the two wires while the workman goes to release the straining
machines the device shown in Fig. 16 is temporarily employed. This is a spring
clamps forced open by means of the screw t until the indentations u u in the jaws are
sufficiently far apart to fit the opposite corners vw, Fig. 14 of the two clips. The
clamp having been fitted on these corners the screw t is slacked so that the clamp causes
the clips to grip the wires and to thus retain them until the straining machines are
released. The clamp is then removed. It is preferred to make the pivot holes of the
clips a little nearer ono end than the other as the drawings show so that by reversing
the position, that is to say, by bringing the shorter end down instead of the longer
the clips will adapt themselves to a thicker wire.
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 1
claim in respect of wire fencing is :-
1. The construction of standards of U section having strengthening ribs as described
and with holes adapted to receive staples for securing the fencing wires in the manner
set forth.
2. The stable hereinbefore described and represented in Figs. 5 and 6 for fastening
or securing the horizontal wires to the standards or suspenders.
3. The staple hereinbefore described and represented in Figs. 7, 8 and 9 for fastening
or securing the horizontal wires to the standards or suspenders.

page_text: 4. The bridge hereinbefore described and represented in Figs. 12 and 13 for the
purpose set forth.
5. The double excentric clip constructed as hereinbefore described and represented
in Figs. 14 and 15.
