MENTS IN THE MANUFACTURE OF BARRED WIRE
Year: 1884

page_text: I CARL KLAUKE, Manufacturer of the town of Müncheberg, near Berlin in the
Empire of Germany do hereby declare the nature of my Invention for IMPROVE-
MENTS IN THE MANUFACTURE OF BARRED WIRE and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :—
My Invention relates to improvements in the manufacture of barbed wire for
fencing and other purposes and is characterised by the simplicity of the construc-
tion and the consequent cheap method of manufacture whereby a thin barb which
requires a minimum of wire is clamped to the chief or main fencing wire.
The attempts made at various times and by various persons to produce barbed
wire with a single main wire have proved entirely unsuccessful.
According to one of these said systems the wire for forming the barb was simply
wound around the main wire so that the said barb could be readily bent back and
unwound from the said main wire in consequence of which said disadvantage the
said system was declared impractical and not fit for general use. According to
a second system the main wire was provided with inclined incisions and the partly
sovered portion of the said main wire bent outwards to form the barb. These barbs
stand at an angle of about 60 degrees so that the object of the barb is not attained
and besides this the main wire is so weakened by these said incisions that the same
is very liable to break.
According to a third system invented by me the loop was formed in the main
wire the barb inserted in the same and then clamped tight but this system was
unsuited for general use as too much wire was consumed by the loop and when the
said wire was stretched the barbs were forced into an inclined position.
It has also been attempted to fix stars of stamped sheet metal to the main wire
but the same disadvantages as mentioned in the other systems appeared.
None of these disadvantages are to be found in my said present invention the
main wire is not weakened by making incisions in the same and retains its straight
position and the coils of which the barbs are formed are so durable that it is
impossible to tear them off.
In order that my said invention may be more fully understood I will now
proceed to more fully describe the nature of my said invention and the method of
carrying the same into effect.
Figure 1 is the plan or top view of a piece of my improved barbed wire.
Figure 2 is an elevation and
Figure 3 a bottom view or a view of the lower side of Fig: 1.

page_text: Figure 4a represents the wire barb after the first operation whereas the
Figure 4b represents the barb completely formed ready to be inserted on the
main wire.
The barbs bare first formed by bending the wire of which the same are composed
in the manner as represented in Figure 4a and then this double loop bent so over
that the same forms one opening for the insertion of the main or fencing wire a as
shown in Figure 4b. The said barb or a larger or smaller number of the same are
then pushed onto the one end of the main wire according to the length of the same
and the distance between the barbs so that the ends of each said barb can be
caught by suitable jaws or other clamping device and so drawn tight that the
coils of the said barb are brought into snug contact with the surface of the main
wire.
If the so prepared barbed fencing wire is now galvanised the zinc deposited will
still further assist in holding the barb in correct position or if desired the barb or
barbs may be passed under a hammer or other equivalent device and subjected to a
blow or to pressure so as to press or force the said barb or barbs into intimate
connection with the main wire and thus prevent the barb from turning on the said
main wire or if desired the main wire with the barb can be guided in front of an
automatic soldering device and each and every barb fixed to the said main wire
by a drop or small quantity of solder in order to attain a like effect.
Although I prefer to use only one stout wire as main wire it is evident that
more than one wire can be employed without in any way departing from the
tenor of my invention.
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
1. The method of manufacturing barbs for wire fencing substantially as and for
the purpose described.
2. The application and employment of the barbs as described in the foregoing
specification or any mere modification of the same for arming fencing wire and
such like substantially as and for the purpose set forth in the foregoing speci-
fication and shown in the accompanying drawing.
3. The method of manufacturing barbed wire fencing whereby barbs of thinner
wire are attached in suitable manner to the main fencing wire which said fencing
wire can consist of one or more separate wires substantially as and for the purpose
described in the foregoing specification.
