An Improved Wire Strainer..
I, ORMEROD BEVILLE GRANVILLE, of 3, George Yard, Lombard Street, in the
County of Middlesex, England, Indian Exchange & Discount Broker, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
:
My strainer is designed to stretch any wire, either single, plain, or barbed; or
wire made up into designs, such as netting.
This strainer consists of two parts Firstly of a lever arm or bar of steel, iron or
other suitable material, flattened at one end, with three equidistant holes through
that end; the distance between these holes regulates the length of the lever arm
and of the links of the chain, to be hereinafter mentioned; for instance, one inch
between each hole requires a lever arm of sixteen inches, with each link of the
chain one and a half inches long:
These sizes may be varied but I prefer near the above mentioned measurements,
through the centre of the aforesaid three holes a link or ring is passed, to which
is attached an ordinary cam plate for gripping the wire through each of the
other two holes a link or ring is passed, having attached thereto a hook, or any
other suitable fastening appliance; the link holding the aforesaid cam plate lies
on the opposite side of the lever arm to which the links holding the said hooks
lie: and the said hooks lie respectively, horizontally and vertically, to suit the
chain, firstly hereinafter mentioned Secondly, of another ordinary cam plate,
attached to which is a chain having alternate horizontal and vertical links: in a
chain having links all one way, the aforesaid hooks would be set to lie one way:
split hooks may be used with chains, having alternate horizontal and vertical
links, by placing the same across the links. The apparatus is intended to stretch
single wires for fencing, also wire netting for fencing and may be applied
either at. strainer posts, the wire being taken either around or through holes in
the posts; in the case of single wires and around the posts in the case of netting,
or it may be applied between posts; the apparatus has a lever double action:
and is worked between the posts by attaching the cam plate E to one portion of
the wire requiring stretching, then attaching hook B to one of the vertical
links 13 then taking the other cam plate D, at the same time holding the chain
taut, and attaching the cam plate D to another portion of the wire then by
moving the lever A from left to right you bring up hook C to the next horizontal
link C, you then move the lever A from right to left and so take up with hook B
another link B' and continue the foregoing operations, link by link, until sufficient
tightness of wire is obtained: the purchase is thus kept on the chain, and the
lever may be dropped at any point, the tension being maintained by the said
hooks whilst the wire is being made secure; the tension is taken off by releasing
the said hooks; by this method the wear and tear is on the chain and not on the

page_text: wire, which saves the wire a large amount of injury: the apparatus is easily
portable. Wire netting is worked in a similar manner to ordinary single wires,
except that it is more convenient to stretch at a post than between posts: the
method used for stretching at posts is by taking a piece of dummy single wire
and making a loop at one end of it, then pass this wire round the post, the free
end of it is then passed through the loop., Cam plate E is now attached to the
wire netting, or in case of a single wire, to the wire to be stretched, and hook B
is inserted into link B of the chain, and the cam plate Dis attached to the said
loose end of the dummy wire, and any slackness in the wire netting or single wire
is taken up on the chain, link by link, as before described in the case of single
wires. When sufficient tightness is obtained the true wire or wire netting is
fastened off on the straining post by staples or other suitable method after which
the straining apparatus and dummy wire are removed. I am aware that, as an
alternative, the lever may be worked on the substance to be stretched, by having
cam or other suitable attachments in place of the hooks, but I do not claim this.
as I prefer the chain: another variation may be made by substituting a ribbed
metal cord in place of the chain or a plain metal cord or rod in place of the chain
in the latter case, having clam or other suitable attachments in place of the
hooks, and, in the former case, by having split hooks, but I do not claim these
methods, as I prefer the chain.
In the accompanying drawings Figure I represents the portion of the apparatus
consisting of the lever arm A with attached hooks B and C, hook B is repre-
sented in a horizontal position, and hook C in a vertical position; and cam
plate D Figure 2 represents the portion of the apparatus consisting of cam
plate E, with chain attached, some of the links of which chain are shown, B' repre-
senting links lying vertically, and C representing links lying horizontally.
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:-
In combination, and for the aforesaid purposes, the whole apparatus, sub-
stantially as described and illustrated by the foregoing specification and accom-
panying drawings.
