Improvements in Wire Fencing.
I, HENRY WATERS HARTMAN, of Beaver Falls, Beaver County, Pennsylvania,
United States of America, Manufacturer do hereby declare the nature of this
nvention 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 wire fencing and for this purpose I have produced an
improved band or ribbon in which the filling-wire is twisted with the line-wires in
such a way that the filling-wire shall pass over one of the line-wires at one side, be
twisted therewith and pass diagonally therefrom at its opposite side to and over the
opposite side of the other line-wire, be twisted with it and pass diagonally therefrom
at its opposite side, whereby the filling-wire is made to embrace the line-wires on
opposite sides of the band at each alternate twisting for the purpose of giving to
such band greater strength, stiffness, and less liability to twist or buckle, than any
woven fencing band formed of three wires, of which I have knowledge.
It is the alternate relation of the filling-wire at its twisting points with the line-
wires and the opposite directions of these twists, whereby the filling-wire leads from one
side of one line-wire to the opposite side of the other line-wire, that causes the filling-
wire to brace and give greater stiffness to the band than can be obtained by passing
the filling wire from and over one side of one line-wire to and over the next line-
wire on the same side, because in such relation the bracing and stiffening function
of the filling wire is to a large extent lost and if such fencing were produced in a
single band, as mine is, it would be liable to twist and buckle at every point.
By means of my improved fencing band I overcome this objection and am able to
produce such a single band by a machine of comparatively simple construction and
in this way cheapen the manufacture of the fencing.
The accompanying drawing shows in side view a portion of my improved fencing-
band or ribbon.
In this band or ribbon-the line-wires a and b maintain their continuous parallel
relation and the filling-wire c is zigzagged diagonally between them and twisted with
them at suitable intervals, at diagonally opposite points, d, and the extent of the
twisting of these two wires will determine the distance between the diagonal strands.
At this twisting the filling-wire passes over the front side of the line-wire ate and
leaves it on the other or rear side at fand crosses diagonally upward to the other
line-wire and over the front side thereof at g and leaves it on the other or rear side
ath thereof, and crossing diagonally downward to the lower line wire over the front
side at i of which line-wire it passes and is twisted, and so on throughout the length
of the strand, making the commencing and ending of the twists alternate on opposite
sides of the line wires or band for the purpose and to produce the band or ribbon
described and shown in the drawing.
In thus forming the band to obtain the advantages stated, it is important to notice
that the twisting of the filling-wire must be in opposite directions on each line wire
that is to say, the twisting of the wires must be effected by revolving the filling
wire alternately outward from the line-wires as indicated by the arrows on these
wires.
While the distance between the diagonal strands is determined by the extent of
the twisting of the two wires, it will be understood that the distance between such
twisting will be regulated and determined by the speed with which the wires are
drawn from the twisting devices, and it is the speed of the drawing device of the
machine which I have organized by producing this wire fencing band, that controls
and determines this matter.
In a former Complete Specification dated February 24th 1892 No. 3627 I have

page_text: shown, described and claimed, such a machine, and I may here state that its
construction and operation is such as to cause the two wires to be intertwisted
whereby a firmly locked twist is obtained, which cannot be the case where one wire
is twisted around another. It may be noted that the filling wire is carried by a
shuttle having both a rotary and horizontal movement, which always carries such
wire above the line wires at the point of starting the twist; while the carriers for
such line-wires are caused to rotate in opposite directions to produce the following
result.
The carrier for the filling-wire and the carriers for the line wires must make one
or more complete rotations together; that the filling-wire must begin each twist
from the upper side of the band on the line-wire and complete it upon the lower side
thereof, thence passing to the upper side of the other line wire making the twist in
like manner; and that the carriers for the separate line wires must be revolved
alternately in opposite directions to make the lock twist stated.
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. The fencing-band or ribbon herein shown and described, consisting of the line
wires and the filling wire twisted therewith in opposite directions, at alternate
points d, the diagonal strands alternating on opposite sides of the band at f—g—h—i, :
for the purpose stated.
2. As a new article of manufacture the fencing band or ribbon as herein described
and shown in the drawing.
Dated this 12th day of April 1892.
