IMPROVED COUPLING FOR METALLIC FENCING"
"A NEW OR
This Invention has for its object a new or improved coupling for metallic fencing
by means whereof such fencing can be readily erected, and removed and a tem-
porary opening formed therein where required and subsequently closed with the
utmost facility and without the assistance of skilled labor. At the same time it
does not require any special construction of fence to render it effective but may be
readily adapted to existing metallic fences if desired
It is therefore obvious that my invention combines the two essential advantages
of economy and convenience
My improved coupling is both simple and effective in construction and can be
manufactured at a merely nominal cost It consists of two union couplings or outer
cones each having a screw thread of any suitable pitch cut thereon or suitable
flanges may be cast thereon to allow of their being bolted to the standard or
upright
Within these outer cones four semi cones are fitted thus forming two inner cones
while suitable holes are made in each of the outer cones or suitable flanges or their
equivalents cast thereon to allow of their being tightly screwed or bolted or
otherwise securely fastened together
The inside surfaces of the senii cones have suitable grooves or teeth cut or cast
thereon so that they firmly grip the rod or wire forming the bar or rail of the
fence when it is inserted therein and screwed up taut
It will thus be seen that the greater the tension on the bar or rail the more
rigidly and tightly the semi cones forming the inner cones of the coupling are
united
The operation of my invention is as follows-The first coupling consists of a
semi coupling furnished with a boss or flange on its outer end and is fitted on a
standard or upright forming either the commencement or termination of the fence.
A bar or rail is put through the outer cone of the coupling for a sufficient distance
and two semi cones are then fitted within such outer cone after which the boss is
fitted either over the screw thread cut on the latter or over the flanges cast thereon

forming a stay for the bar or wire is then put up followed by a second standard
which is erected at any convenient distance from the first One of the outer
cones before described is then put on the bar or rail and brought back nearly to
the hole formed in the standard to allow of the passage of the bar therethrough
after which two of the semi cones are fitted in such outer cone and a second
outer cone is then put on the end of another bar or rail and two semi cones fitted
therein in a like manner after which the two outer cones are united by screwing
them together and tightening them up to the requisite rigidity
This operation is repeated until a sufficient length of fencing has been erected
thus forming a perfect continuous fence-which when erected in this manner
possesses the following advantages
1° No skilled labor is required either to erect or take down the fence
2° An opening for entrance or exit can be made at any part of the fence and
subsequently closed with the utmost facility
3° When not in use or when being-packed for carriage the fence can be stored
in a far less space than that required for packing hurdles thus materially enhancing
its convenience and reducing the cost of carriage
