PROVISIONAL SPECIFICATION.
Improvements in Wire Fencing.
I, HENRY WATERS HARTMAN, of 108 Fourth Avenue, Pittsburgh, Penn-
sylvania, United States of America, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to an improved wire fence material or fabric, and relates.
more particularly to the production of a band or ribbon constructed of three wires
or strands, of which the two outer wires are parallel and are interwoven with and
retained in their parallelism by a third, intermediate wire.
Heretofore fence bands or ribbons have been manufactured, of varying form and
of three or more strands of wire, but have had their strands so intertwiste: or
interwoven. at their points of contact, that the intermediate wires, leaving one of
the parallel wires upon the upper side, have crossed over and encircled the opposite
parallel wire from the upper side. A band thus constructed naturally tends to
take a spiral or twisted form and it is difficult to pack or "spool".for transportation.
It is moreover very difficult to set up in place, and from its tendency to twist, does.
not look so well, in place, as a band which is straight and which has no such
tendency to twist into spiral form.
According to my invention I construct the said wire fabric in such a manner,
that the outer parallel wires are always maintained under tension during the
operation of weaving, and the intermediate wire, which is passed alternately from
one to the other, is rotated around with each parallel wire one or more revolutions.
By this method the intermediate wire which joins a parallel wire on one side leaves
it from the other side, and since the two are rotated together they must, whether
they make one or more revolutions, be locked together by the intimate nature of
the twisting.
In order that the tendency of the band, to follow the twist of the intermediate
wire, when such twist is continuous in one direction, may be overcome, I prefer to
cause the two parallel wires to be rotated in opposite directions, and alternately,
each rotating only when the shuttle carrying the intermediate wire is in contact
with it. It will be seen, that the intermediate wire being twisted to the right.
upon the one parallel wire is twisted to the left upon the other parallel wire and all
tendency of the band to twist is corrected within itself.

Improvements in Wire Fencing.
I, HENRY WATERS HARTMAN, of 108 Fourth Avenue, Pittsburg, Penn-
sylvania, United States of America, Manufacturer 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 an improved wire fence material or fabric and relates
more particularly to the production of a band or ribbon constituted of three wires
or strands of which the two outer wires are parallel and are interwoven with and
retained in their parallelism by a third intermediate wire.

In the accompanying drawing I have shown a portion of a fencing band
constructed according to my invention.
Heretofore, fence bands or ribbons have been manufactured, of varying form
and of three, or more strands of wire but have had their strands so intertwisted or
interwoven at their points of contact, that the intermediate wires leaving one of the
parallel wires upon the upper side have crossed over and encircled the opposite
parallel wire from the upper side. A. band thus constructed naturally tends to
take a spiral or twisted form and it is difficult to pack or "spool" for transportation.
It is moreover very difficult to set up in place and from its tendency to twist, does
not look so well, in place, as a band which is straight and which has no such
tendency to twist into spiral form.
According to my invention I construct the said wire fabrics in such a manner,
that the outer parallel wires are always maintained under tension during the
operation of weaving, and the intermediate wire, which is passed alternately from
one to the other is rotated around with each parallel wire one or more revolutions.
By this method the intermediate wire which joins a parallel wire on one side leaves
it from the other side, and since the two are rotated together they must. whether
they make one or more revolutions, be locked together by the intimate nature of
the twisting. In order that the tendency of the band to follow the twist of the
intermediate wire, when such twist, is continuous in one direction may be overcome,
I prefer to cause the two parallel wires to be rotated in opposite directions and
alternately each rotating only when the shuttle carrying the intermediate wire is in
contact with it. It will be seen that the intermediate wire being twisted to the
right upon the one parallel wire is twisted to the left upon the other parallel wire
and all tendency of the band to twist is corrected within itself.
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 :-
1st. As a new article of manufacture a wire fence band consisting of two parallel
wires interwoven with an intermediate wire which is, alternately and at fixed
distances intertwisted with each of said parallel wires in the manner hereinbefore
described and as shown in the drawing.
2nd. In a wire fence band constructed of two outer parallel wires and a third
intermediate wire, alternately and at fixed intervals intertwisted with said parallel
wires, the method of rotating the outer parallel wires with the intermediate wire
alternately in opposite directions whereby the twisting in the one direction upon
the one side is corrected by the twisting in the opposite direction upon the other
side and the fabric is maintained straight as hereinbefore described and shown in
the drawing.
3rd. A wire fence fabric wov n of two parallel outer wires intertwisted with a
third intermediate wire said intermediate wire being alternately intertwisted with
each outer wire in a continuous series of angular spaces whereby the three wires
form a ribbon or band as herein before described and shown in the drawing.
