IMPROVEMENTS IN BARB-WIRE FOR FENCES
Year: 1882

page_text: LETTERS PATENT to Friedrich Carl Glaser, of Berlin, in the Kingdom of
Prussia and Empire of Germany, Engineer and Patent Solicitor, for an
Invention of "IMPROVEMENTS IN BARB-WIRE FOR FENCES" A communication
from Albert Schniewindt, a person resident at Neuenrade, Westphalia, in the
Kingdom of Prussia, and Empire of Germany.
PROVISIONAL SPECIFICATION left by the said Friedrich Carl Glaser at the
Office of the Commissioners of Patents on the 4th July 1882.
FRIEDRICH CARL GLASER, of Berlin, in the Kingdom of Prussia, and Empire of
Germany, Engineer and Patent Solicitor. "IMPROVEMENTS IN BARB-WIRE FOR
FENCES." A Communication from Albert Schniewindt, a person resident at
Neuenrade, Westphalia, in the Kingdom of Prussia, and Empire of Germany.
The object of this Invention is to give greater protection to farms, fields,
plantations and other enclosures by means of wire fencing, and it consists in
providing these wires with barbs, pricks, spikes or sharp projections stamped and
bent outward from the body of the wire. These wires are provided with a large
number of such barba bent upward as well as downward to give the wire two
armed sides.
The processes hitherto employed to make barbed wire fencing are complicated
whilst the value of this new product consists in the simplicity of the process of
providing wires with barbs in one piece with the wire.
The barbs are produced by means of two eccentric-stamps which are arranged
in such a way that one working downwards forms the barb going downwards, and
the other working upwards forms the barb going upwards.
The Stamp-cutters are arranged so that the wire which passes on in an oblique
direction through the stamps by means of self acting crabs is struck by the cutters
in such a way that a splint is cut out of the wire-body; the end of this splint
adheres to the wire whilst its sharp point is bent downward or upward by means
of an oblique guide piece attached to the cutter.
In providing a strong barbed wire, it is preferred, in order not to weaken the
wire, to use wire of an oval shape in cross section; the barbs being then stamped
out of both of the small sides of the oval,

FRIEDRICH CARL GLASER of Berlin in the Kingdom of Prussia and Empire of
Germany Engineer and Patent Solicitor "IMPROVEMENTS IN BARBED WIRE FOR
FENCES. A communication from Albert Schniewindt a person resident at
Neuenrade Westphalia in the Kingdom of Prussia and Empire of Germany.
The object of this invention is to give greater protection to farms, fields,
plantations, and other enclosures by means of wire fencing, and it consists in
providing these wires with barbs, pricks, spikes, or sharp projections stamped and
bent outward from the body of the wire. These wires. are provided with a large
number of such barbs bent upward as well as. downward to give the wire two
armed sides.
The processes hitherto employed to make barbed wire fencing are complicated
whilst the value of this new product consists in the simplicity of the process of
providing wires with barbs in one piece with the wire.
By means of excentric presses metal wire may be so cut into, that barbs or spikes
may be formed by the simultaneous bending off of the cleft points formed by the
arrangement of the knives.
Figures 1 and 2 of the accompanying Sheet of Drawing show a barbed wire
for fencing produced by the combination of two excentric presses, the stamp of the
one press working from above forming a splint, spike or barb on the one side of
the wire, whilst the other stamp simultaneously working from below forms a
second barb on the opposite side, at a regulated distance from the first barb.
Figures 3 and 4 shew a barbed wire for fencing manufactured on a similar
machine but with the difference that this wire on being drawn through the press
turns continuously round its axis, whereby the points become arranged in a helical
line around the wire. Finally Figure 5. shews a barbed wire for fencing which
may be produced from rolled wire of any desired section. This rolled wire must
however by means of a special rolling process be provided with strengthening
swellings or bosses a a. The rolling process to obtain these latter consists in
arranging recesses in the periphery of the roller corresponding to the distances at
which it is desired to have the barbs on the wire. In the rolling of the wire these
recesses give to the same at the places where the barbs are to be cut in or formed,
a corresponding increase of strength. The cleaving or cutting out of the splints,
spikes or barb is effected in the same manner as in the case of the barbed wire
represented in Figures 1 and 2.
Having now described and ascertained the nature of the Invention communi-
cated to me as aforesaid and in what manner the same is or may be performed.
I claim as secured to me by the hereinbefore in part recited Letters Patent :-
Firstly-The barbed wire for fencing represented in Figures 1 and 2 which is so
produced from drawn or rolled wire of oval, round, and square cross section that
the barbs are alternately cleft or cut out from above and from below, therefore at
a suitable distance apart from each other and at opposite sides of the wire,
substantially as described.
Secondly-The barbed wire for fencing represented in Figures 3 and 4 which is

page_text: formed out of ordinary round wire by cleaving or cutting out; the wire being
turned round as it is being drawn through the press whereby the barbs become
situated in a helical line round the wire substantially as described
In witness whereof I the said Friedrich Carl Glaser have hereunto set my
hand and seal this Twenty ninth day of December in the year of our
Lord One thousand eight hundred and eighty two.
