"IMPROVEMENTS IN WIRE FENCING WITH SPURS OR POINTS AND IN MACHINERY
TO BE EMPLOYED IN CONNECTION THEREWITH a communication to me from Carl
Klanke of the town of Müncheberg in the German Empire aforesaid

This Invention relates to improvements in wire fencing with points or spurs and
in machinery to be employed in connection therewith.
The object of this said invention is to produce wire fencing with points or
spurs in a simple and economical manner whereby one stout strong fencing wire
or a wire rope is so employed that the spurs or parts provided with sharp points
are firmly bound or attached to the chief or fencing wire or wire rope. The
said spurs or pointed pieces of wire are made either by hand or by means of a
suitable machine. When machinery is employed the spurs or points are auto-
matically cut off, bent up into a suitable form and introduced into an eye loop
or opening formed by bending the fencing wire or rope in suitable manner.
Both of these said operations can be combined in one machine or be carried out
in separate machines; in the first case the spur or point is bent up, the wire cut
off and automatically fed into the eye or loop of the fencing wire or rope.
The wire for forming the spurs or points is thinner than the fencing wire or
rope and is either bent up by hand or caused to pass through a suitable pair of
feed rollers which said rollers are drawn by means of suitable gearing and strap
drums.
The axle to the strap drums and one of the wheels of the toothed wheel gearing
is also provided with a bevil wheel gearing into a second bevil wheel the shaft of
which is carried in suitable bearings and is provided at the opposite end with a
suitable disc or wheel with cam groove in the forward surface of the same.
After the wire for forming the spur or point has passed the feed rollers it is cut
off automatically in suitable lengths and so that a sharp point is formed at each end
of the said piece of wire. The feed rollers are partially cut away so as to attain a
periodical feed.
During the cutting off operation the wire enters the recesses in the feed rollers
and is consequently at rest. At the same moment when the wire enters the said
recesses in the rollers a stamp or cutter operates on the wire and cuts the same off
in an inclined direction corresponding to a suitable cut or cavity in the machine
beneath the said cutter. This said cutter or stamp is operated by means of an

page_text: excentric attached to a suitable shaft running parallel to the feed rollers and
provided with strap drum or suitable bearing. The cutter or stamp moves in
suitable guides in the frame of the machine is forced down by the excentric
rotating with the said shaft and is again raised by means of a counterweight or
other equivalent means.
The piece of wire for forming the spur so cut off falls through the opening or
cavity mentioned above slides onto a suitable incline of a slide or stamp until it
comes between this said stamp and a die which is provided with a suitable surface
for forming the said spur.
In moving forward the said slide, piston or stamp forces the wire into the cavity
of the die and the cavity in the face of the slide or stamp whereby the said spur is
formed in one operation.
The slide or stamp is operated by means of bevil gearing through which said
gearing the excentric aforementioned is set in operation and in this way a
back ward and forward motion of the driving rod and consequently of the slide or
stamp attained.
The spur is now complete so that by the next stroke of the slide or stamp to cut
off a fresh length of wire the spur previously formed is forced downwards by a
finger attached to the stamp or slide from whence the said spur is fed into the eye
or loop formed in the chief wire or wire rope.
In the second part of the machine or when separate machines are employed in
the second machine the chief or fencing wire or wiro rope is so bent or wound
that an eye or loop.is formed. The said wire is fed into the machine by means
of feed rollers which receive their motion from a suitable drum or pulley-by-
means of straps until such said wire comes between two stops, pivots or studs. -
One of these said stops pivots or studs is attached to one of the rollers which said
roller oscillates for a half revolution.
This-oscillation-of-the-said-roller-is produced through the rotation of a vertical
shaft which is provided with a driving or connecting rod which said rod is
connected to an excentrical pivot on a suitable disc on a shaft supported in suitable
bearings.
The vertical shaft is rotated by means of suitable bevil gearing.
The rotation of the stop, pivot or stud forms an eye or loop in the fencing wire
or rope..
As soon as the said eye or loop is formed the roller makes its return semi-
revolution and the second stop pivot or stud having reached its highest point now
falls back.
The wire is now free and is fed forward in guides on the bed or table onto a
suitable lug so that the centre of the bend in the wire lays on the same.
A piston
now moves forward and presses the bend in the wire into the form of a circular
eye or loop after which the said wire is fed further on until the said eye or loop
comes under a second piston or stamp. At this moment the spur formed by the
previous operation is fed into the eye or loop when the piston or stamp presses the
eye or loop firm onto the spur or pointed wire knot.
During this pressing of the chief or fencing wire a cam comes into operation
and draws the eye or loop tight around the spur or pointed knot. The pistons
or stamps slido in guides in the frame of the machine and on the bedplate and are
forced downwards by means of suitable excentrics. The pistons or stamps are
raised by means of a suitable spring.
The fencing wire is now complete and provided with spurs or points and can be
wound onto a drum or other suitable device.
