WILLIAM PHILPOT CURRAN BAIN, of Edinburgh, in the County of Mid-Lothian,
North Britain. "IMPROVEMENTS IN STRAINING POSTS FOR WIRE FENCES AND IN
APPARATUS CONNECTED THEREWITH."
This Invention, which has for its object improvements in straining or winding
posts for wire fences, and in straining or winding drums, reels, or bobbins therefor,
relates to that class of straining or winding posts constructed of bar iron of circular
section, and in the said posts the improvement consists in dispensing with all the
appurtenances or accessories hitherto used as adjuncts to the straining or winding
drums, reels, or bobbins, and employing a plain circular bar of iron merely to
constitute the post, whereby the construction and cost of such posts is simplified
and lessened.
The new or improved straining or winding drum, reel, or bobbin constructed in
accordance with this Invention consists of a hollow cylinder capable of sliding
vertically upon the straining or winding post herein before referred to. The drum,
reel, or bobbin is provided with flanches at its upper and lower ends, one of which
is of sufficient depth or thickness to permit of one or more slots or holes being made
in its periphery at right angles to the vertical axis of the post. In each flauch a
series of holes concentric with the circumference, and passing vertically through
the flanch, is made, the holes in one flanch being opposite to those in the other.
In preparing to strain a length of wire extending between two posts an end of
the wire is tied around one post, and the other end is bent and passed through one
of the vertical holes in the top or bottom flanch of the winding drum, reel, or
bobbin on the next post. A key or lever is then inserted in the horizontal slot or
hole herein before referred to, and by means of it the drum, reel, or bobbin is turned
round the post, thereby winding on the wire until a sufficient strain or tension has
been produced upon it, which being effected a pin, cotter, or wedge is passed
downwards through two of the vertical holes in the flanches in such a manner that
the wire is confined between it and the circumference of the drum, reel, or bobbin,
and is so prevented from becoming unwound when the pressure on the key or
lever is released. The strain or tension on the wires holds the drums, reels, or
bobbins in position on the post.

page_text: Instead of tying the end of the wire to the post, as hereinbefore set forth,
provision may be made for attaching it to a drum, reel, or bobbin; and instead of a
horizontal slot or slots being made in one flanch of each drum, real, or bobbin, as
and for the purpose described, a nut or other equivalent projection may be cast
or formed on each drum, reel, or bobbin, and a spanner used for turning it round 5
in winding or straining the wire, and in lieu of holding the wire by means of a
pin, cotter, or wedge passing through holes vertically, other equivalent means may
be used for that purpose.
