"IMPROVEMENTS IN WIRE FENCING WITH SPURS BARBS OR POINTS AND IN
MACHINERY TO BE EMPLOYED IN CONNECTION THEREWITH a communication to
me from Carl Klauke of the town of Müncheberg in the German Empire aforesaid.
This Invention relates to improvements in wire fencing with points barbs or
spurs and in machinery to be employed in connection therewith.
The object of this said invention is to produce wire fencing with barbs points or
spurs in a simple and economical manner whereby one stout strong fencing wire or
a wire rope is so employed that the barbs spurs or parts provided with sharp points
are firmly bound or attached to the chief or fencing wire or wire rope. The said
barbs spurs or pointed pieces of wire are made either by hand or by means of a
suitable machine-When machinery is employed the barbs spurs or points are
automatically 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 barb 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 barbs 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 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 barb 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

page_text: 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 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 or barb.
:
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 or
barb 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 or barb is now complete. so that by the next stroke- of the slide or
stamp to cut off a fresh length of wire the spur or barb previously formed is forced
downwards by a finger attached. to the stamp or slide from whence the said spur
or barb 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 wife 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 balf 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 barb or pointed knot,
The pistons or stamps slide 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 barbs or points and
can be wound onto a drum or other suitable device.
