I JULIUS SCHMIDT of Hagen, Westphalia in the Empire of Germany Manu-
facturer, do hereby declare the nature of my invention for ToOTHED ROLLED FENCING
WIRE to be as follows:-
Of late, wire with points or other sharp projections, has been employed for fencing,
to prevent cattle from damaging the saine. As a rule, these projections have been
made of small pointed pieces of tin and are then intertwined between two or more
wires; also the wire has been furnished with small ribs and out of these ribs small
pieces have been cut by a machine, so that teeth were formed. By this procedure
there is a great waste and the ribs are weakened.
According to the present invention toothed wire is made by the cold process of
shaped wire, by letting the wire pass through shaped rollers. By this method the
material of the ribs is not cut away, but indented to the roots of the ribs. In
consequence of this, a peculiar tooth form is produced, more particularly if the ribs
are sharpened in the form of a blade of a knife. The points or teeth by going.
through the rollers are spread from the top of the teeth to the base in such a way
that a hip is formed. In consequence of this circumstance a very favourable
strengthening of the tooth is produced. The material that at first filled the gaps is
entirely pressed down and all loss of material avoided. As already indicated the wire
may receive a great variety of shapes. It must have, however, always one or two
small ribs out of which the teeth can be made.

page_text: I, JULIUS SOHMIDT, of Hagen, Westphalia in the Empire of Germany Manu-
facturer 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 :—
Of late wire with points or other sharp projections has been employed for fencing,
to prevent cattle from damaging the same.
As a rule the projections have been made of small pointed pieces of tin and are then
intertwined between two or more wires, also the wires have been furnished with small
ribs fig. 1, & out of these ribs small pieces have been cut by a machine so that
teeth were formed. By this procedure there is a great waste and the ribs are
weakened.
According to the present invention toothed or pointed wire is made by the cold
process of shaped wire as shown in fig. 1 to 8, by letting the wire pass through toothed
rollers as shewn in fig. 15. The two rollers A and B, or only one of them are
provided with teeth Z running parallel to the axle.
On passing the shaped wire figs. 1 to 8 through these rollers the material of the
ribs is not cut away, but indented to the roots of the ribs. In consequence of this
a peculiar tooth form is produced, more particularly if the ribs i aro sharpened in the
form of a blade of a knife, as for instance profile fig. 5. This rolled tooth form is
shewn in figs. 9 to 11.
The points or teeth by going through the rollers are spread from the tops of the
teeth to the base in such a way that a hip o is formed as shewn in fig. 11 (cut).
In consequence of this circumstance a very favorable strengthening of the tooth is
produced. The material that at first filled the gaps is entirely pressed down & all
loss of material avoided.
As already indicated the wire may receive a great variety of shapes, it must have,
however, always one, two, or more small ribs out of which the teeth can be made.
The tooth form also may vary, the figs. 12 & 13 give two modifications of the
teeth l.
The wire as shewn in fig. 13 with saw shaped teeth is particularly adapted
for nails.
Fig. 14 shows a nail made of this wire.
Having now particularly described & ascertained the nature of my said invention,
& in what manner the same is to bo performed, I declare that what I claim is :
1. Toothed wire made by rolling or indenting the teeth in the side ribs of suitable
