Improvement in Barb Wire.
I, EWALD SCHÖNEBERG, Factory Manager, of Karl Antonstrasse 18, Dusseldorf,
in the German Empire, do hereby declare the nature of this invention to be as
follows:
The main wire of the improved barb wire is prismatic, of triangular, quadratic,
hexagonal or other angular section, with flat or concave sides, or it may be fluted
or grooved like a column; those portions of the main wire, however, which carry
the barbs, have a different section, or the edges at those parts are out of line with
the edges of the main part, in order to prevent the accidental shifting of the barb
or spike coil in a longitudinal direction. These short parts of the main wire may
be triangular, quadratic, polygonal, flat, oval, or grooved.
If it is desired, that the barbs or spikes can be turned on the main wire, those
parts of the latter which carry the spikes, are of circular section.
The thin wire from which the spikes or barbs are formed, is secured, to the
main wire by coiling it several times round the latter. The said thin wire may be
prismatic, round, or of any other convenient shape.

I, EWALD SCHÖNEBERG, Factory Manager, of Karl Antonstrasse 18, Düsseldorf,
in the German Empire, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This invention relates to barb-wire suitable for wire-fencing, and more particularly
to the shape of the main-wire or core which carries the spike coils, as indicated by
the
accompanying drawings Figs. 1 to 6, which represent various forms of fencing
wire embodying my improvements.
The main wire of the improved barb wire is prismatic, as shown by Figs. 1 to 4,
of triangular, quadratic hexagonal or other angular section, with flat or concave
sides, or it may be fluted or grooved, as indicated by Figs. 5 and 6, those portions
of the main wire, however, which carry the barbs, have a different section, (Figs. 1
and 2), or the edges at those parts are put out of line with the edges of the main
part (Figs. 3 and 4) in order to prevent the accidental shifting of the barb or
spike coil in a longitudinal direction. These short parts of the main wire may be
triangular, quadratic, polygonal, flat, oval or grooved.
If it is desired, that the barbs or spikes can be turned on the main wire, those
parts of the latter which carry the spikes, are of circular section.
The thin wire from which the spikes or barbs are formed, is secured to the main
wire by coiling it several times round the latter. The said thin wire may be
prismatic, round or of any other convenient shape.

page_text: In the drawings, Fig. 2 is a section along line A-B, Fig. 4 a section along
line C-D and Fig. 6 a section along line E-F. These sections show the shape
of the main wire at the points which carry the spike coils.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. Barb-wire consisting of a prismatic, grooved or fluted main wire, and spike
coils mounted on the same, those parts of the main wire which carry the spikes
having a different shape from the rest, or being placed out of line with the same,
substantially as described and for the purpose specified.
2. Barb-wire in which the core or main wire is fluted or grooved, substantially
as described with reference to Fig. 6.
