I, WILLIAM ORR of 45 West Nile Street Glasgow in the County of Lanark,
Merchant, do hereby declare the nature of this invention to be as follows:--
This invention relates to improvements in strainers for the wires of wire fencing
and whilst applicable to various forms of straining posts or standards the improved
strainers are especially applicable to and intended to be used in conjunction with
tubular or hollow standards of the construction set forth in my Specification No. 8570
A.D. 1885.
The improved strainer consists of a hollow winding drum of such diameter as to be
capable of being slipped over the tubular or hollow post or standard the said drums
being maintained at the proper position upon the post according to the number of
wires in the height of the fence by sleeves or distance pieces. In erecting the straining
post a sleeve of such length as to support the lowest winding drum at the proper
distance from the ground level is first slipped over the standard and secured in position.
A winding drum is then slipped down the standard and next a loose collar or ring then
another winding drum and after that a sleeve of the required length to give the
requisite distance between the drums for the lower and those for the next higher
lengths of wire in the fence and so on until the upper lengths of wire are provided
for, a nut or cap being screwed or otherwise secured on the upper end of the standard
so as to make the adjustment permanent.
By the provision of two winding drums contiguous to each other as described the
lengths of wire extending both to the right and left are or may be strained at the
same post. The drums are turned so as to strain the wires by means of a wrench or
key the jaw of which is applied to a paned portion on the drum and to prevent the
drums from slipping back each of them may also have ratchet teeth formed around it,
the teeth of the higher drum in each pair being on the upper edge and those of the
lower drum on the under edge. A pawl composed of a W or like waved spring is
placed inside the hollow standard and so that its ends project through the vertical slot
extending from top to bottom of the standard as described in my before referred to
Specification. The sleeves or distance pieces are also slotted to permit of the spring
passing through so that they may bear on the ratchet teeth of the winding drums.

page_text: Under another arrangement back slipping of the drums may be prevented by
forming each of them with a series of slots around it and passing a pin through one
of these slots and through the slot or a hole made in the standard. Instead of slipping
the hollow winding drums over the straining post or standard they may be carried in
jaws passed over and secured on the post the wire in that case being strained by a key
having a circular eye passing over the tubular part of the drum and a dividing rib
which enters a recess or slot made in the end of the tube for its reception. In this
case back slipping of the drum may be prevented by a pin inserted into one of a series
of holes made in a flange on the drum and passed through a hole in the cheek or jaw
or the flange may be formed with ratchet teeth into which the point of a pawl centred
on the jaw enters.

Improvements in Strainers for Wire Fencing.
I, WILLIAM ORR of 45 West Nile Street, Glasgow, in the County of Lanark,
Merchant 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 strainers for the wires of wire fencing
and whilst applicable to various forms of straining posts or standards the improved
strainers are especially applicable to and intended to be used in conjunction with
tubular or hollow standards of the construction set forth in the Specification filed
under my Patent dated July 15th A.D. 1885 Number 8570.
The figures
on the appended sheet of drawings illustrate the improvements constitu-
ting this invention and as shown in elevation at figure 1 and in vertical section at figure 2
the improved strainer consists of a hollow winding drum a of such diameter as to be
capable of being slipped over the hollow or tubular post or standard b, the said drums
being maintained in proper position upon the post (according to the number of wires
in the height of the fence) by sleeves or distance pieces c. In erecting the straining post a
sleeve c, of such length as to support the lowest winding drum a, at the proper distance
from the ground level is first slipped over the standard b, and secured in position. A
winding drum a, is then slipped down the standard and next a loose collar or ring d,
which at a part of its periphery is recessed on its upper and under side to enable the
end of each wire to be easily passed into a hole e, made in the drum to receive it the
wire from one direction having its end inserted in the under drum a, and that from
the opposite direction in the upper drum which is separated from the lower one by the
ring d. The upper drun a in each pair is maintained at the requisite distance from
the lower one of the pair immediate above by another sleeve c, of the required length
and so on until the upper lengths of wire are provided for, a nut or cap as seen at f
figure 4, being screwed or otherwise secured on the upper end of the standard so as to
make the adjustment permanent.
The drums a, are turned so as to strain the wires by means of a wrench or key the
jaw of which is applied to the paned portion g, on the drum and to prevent the drums
from slipping back each of them has ratchet teeth h, formed around it, the teeth of the
higher drum in each pair being on the upper edge and those of the lower drum on the
under edge. A pawl composed of a W or like waved spring i, is placed inside the
hollow standard and so that its ends project through the vertical slot extending from
top to bottom of the standard as described in my before referred to Specification. The
sleeves or distance pieces c, are also slotted to permit of the ends of the spring passing
through so that they may bear on the ratchet teeth of the winding drums, and maintain
the drums in their adjusted position.
Under another arrangement shown at fig. 3, back slipping of the drums may bo
prevented by forming each of them with a series of holes j, around it and passing a
pin through one of these holes and through the slot or a special hole made in the
standard.

page_text: Instead of slipping the hollow winding drums over the straining post or standard
as hereinbefore described they may as seen in plan at figure 5 be carried in
jaws k, these jaws having each either an eye through which the standard passes or as
shown a sole or palm k¹ secured against the post or standard. In this arrangement
the wire is strained by a key figure 6, having a circular eye l, passing over the tubular
part of the drum a, and a dividing rib m, which enters a recess or slot n, made in the
end of the tube for its reception. Back slipping of the drum in this case may be
prevented by a pin inserted into one of a series of holes made in a flange o, on the
drum as indicated at figure 7 the pin also passing through a hole in the cheek or jaw k,
or the flange o, may as seen at figure 8, be formed with ratchet teeth into which the
point of a pawl p centred on the jaw enters.
The arrangements of strainers described with reference to figures 3, 5, 7 and 8 of the
drawings are equally applicable to hollow or tubular and to solid straining posts or
standards.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is
:-
1. In wire fencing a strainer consisting of a hollow drum having a hole for the
insertion of the end of the wire, a paned part for the application of a key or turning
device, and a series of ratchet teeth with which is geared a spring pawl substantially
as described.
2. In wire fencing the combination, on a post, of two strainers separated from each
other by a ring or collar and each consisting of a hollow drum having a hole or slot
to receive an end of the wire, a paned part for the application of a turning device, a
series of ratchet teeth around the top of the said paned part and a spring pawl geared
with the said tooth substantially as described.
3. In wire fencing a strainer consisting of a hollow drum having a hole or slot to
receive the end of the wire, a paned part for the application of a turning device and a
neck perforated with a series of holes to receive a securing key or pin substantially as
described.
4. In wire fencing the combination on a post of two strainers for each line of wires
the strainers being separated from each other by a ring or collar and each consisting
of a hollow drum having a hole for the reception of an end of the wire, a paned part
for the application of a turning device and a neck perforated with holes to receive a
securing pin or key substantially as described.
5. In wire fencing the combination of a tubular post having a spring pawl at its
interior with ends projecting through a vertical slot extending the length of the post
and a series of hollow straining drums arranged in pairs and constructed as described
with reference to figures 1 and 2, each drum being separated from the next by a loose
collar and each pair spaced from the next by a distance sleeve having slots at its upper
and lower ends for the throughward passage of the pawls substantially as set forth.
6. In wire fencing the combination of a solid post and a series of hollow straining
drums arranged in pairs and separated by a loose collar each pair being spaced from
the others by distance sleeves and each drum having a series of holes around a neck
for the passage of a securing key into the post substantially as described.
7. In combination with a hollow or solid straining post in wire fencing a tubular
winder or strainer constructed substantially as described with reference to figures 5, 7
and 8 of the appended drawings.
