nature of this invention to be as follows:
My invention relates to improved machinery for manufacturing barbed wire the
barbs of which are formed of pieces of stamped metal. The machine consists of two
distinct parts, namely one for stamping the barbs, and the other for twisting them up
in the wire.
The barbed wire consists of three wires twisted together between which are inserted
at distances apart stamped pieces of metal of a shape such as is shewn at Fig. 6 of the
accompanying drawings.
Barbed wire of this nature is at present made by hand, and in addition to the com-
paratively expensive manufacture, this has the disadvantages that the twisting of the
wire is not regular and that the barbes are not sufficiently tightly held in the wires, so
that they fall out.
My improved machine for manufacturing such barbed wire obviates these defects
and enables the wire to be produced rapidly at a small cost.

machine, Fig. 2 is a front view of the punching machine, Figs. 3 and 4 are enlarged

together. The stem of the fork is hollow and contains a slide having a projection that
slides in a helical slot in the stem, so that on pushing against the projection the slide
will be partly extended from the fork. The stem of the latter also carries an arm D,
the lower part of which bears upon the head of a rod or lever E held by a
spring R. The arm 1) carries a pivotted lever G having a forked upper end, and two
springs.

arm D passes over the upper end of the rod E which on being released thereby, is
drawn back by the spring R and strikes sharply against the lower end of the
lever G.
This then pushes against the projection of the slide which is thrown forward and
thereby throws the barb held by the fork into the centre of the wire strand, where it
is at once secured by the twisting together of the wires, which embrace it, and the
strand is then drawn onwards and coiled on the roller.
When the barb has been thrown forward the punch rises, the spring fixed on the
arm D moves the slide back into its original position, as do also all other parts above
described, and the operation is repeated.

page_text: I, LEON HEN of Brussels, in the Kingdom of Belgium, 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 :-
My invention relates to improved machinery for manufacturing barbed wire the
barbs of which are formed of pieces of stamped metal. The machine consists of two
distinct parts namely one for stamping the barbs, and the other for twisting them up
in the wire.
The barbed wire consists of three wires twisted together between which are inserted
at distances apart stamped pieces of metal of a shapo such as is shewn at Fig. 6 of the
drawings accompanying my Provisional Specification.
Barbed wire of this nature is at present made by hand and in addition to the
comparatively expensive manufacture this has the disadvantages that the twisting of
the wire is not regular and that the barbs are not sufficiently tightly held in the wires,
so that they fall out.
My improved machine for manufacturing such barbed wire obviates these defects
and enables the wire to be produced rapidly at a small cost.
On the drawings accompanying my Provisional Specification dated 13th June 1887,
Fig. 1 shews a side elevation of the complete machine. Fig. 2 is a front view of the
punching machine.
Figs. 3 and 4 are enlarged detail views of parts thereof. Fig. 5 is a view of the
rod T and Fig. 6 shews the form of the barb. The twisting up of the wires is effected
in the usual manner, and will be readily understood from the drawing, the wire strand
is coiled up on a wooden roller Q which when filled is removed and replaced by
another one.
The principal part of the machine is the punching apparatus by which the following
operations are carried out.
1. The barb is stamped out.
2. The two wings of the barb are bent in opposite directions, so that it consists of
three parts lying in different planes.
3. The barb thus formed is, inserted into the wires.
These several operations are effected as follows:-
A strip of metal having the width of the barb is introduced between the two
cylinders C and Cone of which is grooved: the shaft A in revolving actuates the
lever I which moves a pawl so as to turn C through part of a revolution, sufficient to
advance the metal strip a distance equal to the length of a barb; being thus brought
under the punch P. This descends against the rod T, the projection on which in
moving downwards first bends downwards one of the wings of the barb, and in
descending farther the projection together with the barb come in contact with a
piece T sliding on T, so that the downwardly bent wing of the barb is nipped between
the projection and the part T' which is pressed upward by a helical spring as shewn
the spring being of such a length that when the rod T rises again the part T' will
remain just below the place where the wing of the barb is bent by the projection.
At the same time that the above operation is-effected, an arm B is moved towards

bend the second wing of the barb in an upward direction, a roller on the upper part
of the punch being made to turn B on its hinge joint for this purpose. While these
operations are being performed the punch also separates the third wing of the barb
from the metal strip, so that the barb can descend as described.
The barb is moved downward by these operations until it arrives at the centre of
the wire strand; the horizontal fork F, the end of which has the necessary shape for
seizing the barb, takes hold of this and moving in the direction of the centre line of
the wire strand presents the barb at the point where the wires are being twisted
together. The stem of the fork is hollow and contains a slide having a projection that
slides in a helical slot in the stem so that on pushing against the projection the
slide will be partly extended from the fork. The stem of the latter also carries an
arm D, the lower part of which bears upon the head of a rod or lever E held by a
spring R.
The arin D carries a pivotted lever G having a forked upper end and two

springs.
This then pushes against the projection of the slide which is thrown forward and
thereby throws the barb held by the fork into the centre of the wire strand, where it
is at once secured by the twisting together of the wires which embrace it, and the
strand is then drawn onwards and coiled on the roller.
When the barb has been thrown forward the punch rises, the spring fixed on the
arm D moves the slide back into its original position, as do also all other parts above
described, and the operation is repeated.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In a machine for the manufacture of barbed wire, the combination with wire
twisting or stranding apparatus of apparatus for punching and shaping barbes
substantially as herein described.
2. In a machine for the manufacture of barbed wire with star shaped barbes the
combination of apparatus whereby firstly the barb with three wings is stamped out of
a piece of sheet metal, secondly two of the wings of the barb are bent in different
directions, so that the three wings all lie in different directions, and thirdly the barb is.
introduced into the strand of wire in which it is secured by twisting.
3. In a machine for stamping out star shaped barbes, the combination of the
cylinders c c one of which is grooved the ratchet lever L, the punch P, the stem Tand
the part T arranged and operating substantially as herein described for stamping out
the barb and bending the one wing thereof downwards..
4. In combination with the apparatus referred to in the preceding claim of
an arm or abuttment B whereby the second wing of the star is raised as herein
described.
5. In a machine for stamping out star shaped barbes, the combination of the
horizontal fork F with hollow stem with an arm D to which are jointed a fork and
two springs, and the stein E held by the spring R for introducing the previously
formed star shaped barbe between the wires of the strand substantially as herein
described.
