Improvements in the Manufacture of Netting.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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;
-
This invention relates to a netting or similar structure having the strands thereof
connected together at intervals, and is main embodied in a novel arrangement
of the strands to form the connecting knot, the object of the invention being to
prevent the slipping of one strand with relation to another, which is liable to
occur when the meshes of the net are stretched. In such netting as now com-
monly made, the strands are usually connected by means of the ordinary "weaver's
knot and pressure on the strands is liable to cause the loop of the knot to pull
through so that the knot slips and widens the mesh.
"
The material embodying the invention is mainly used for fish nets, and when
strands are connected by means of the weaver's knot a large and powerful fish will
frequently press against the strands in such a way as to cause the loop to pull
through and the knot to slip so that the mesh widens sufficiently to let the fish
escape. This defect is practically obviated in accordance with the present inven-
tion by giving the strand which passes through the loop a turn or bight around
one of the other strands beyond the said loop so that an enlargement is formed
which will usually prevent said strand from being pulled through the loop; while
even if it is pulled through, the other strand will be to a large extent prevented
from slipping.
In the accompanying drawing:-
Figure 1 is an enlarged view of two strands at the point where they are fastened
together, showing the relation of the said strands to each other when the knot is
formed; Figure 2 is a view on a smaller scale showing one mesh of netting or
like structure to illustrate more fully the manner in which the strands are arranged
and knotted together; and Figures 3 and 4 are similar views showing a modifica-
tion.
The material embodying the invention comprises two sets of strands a and b
which alternate along the fabric as indicated in Figure 2, each strand extending
along the material in a zigzag direction and being connected first with a strand b
at one side and then with another strand b at the opposite side, the strand 6 being
arranged in the same way with relation to the strand a.
In accordance with the present invention, the strands are connected by forming
simple loops in each strand of one set at each point of connection, and twisted
loops in the other strand, the simpler loops being herein shown as formed in the
strands a, the two ends crossing each other and forming what may be described
as the upper member a* and lower member a³ of the loop.

page_text: The strand b in which the twisted loops are formed is shown in Figures 1 and 2
as passing through the loop in the strand a above the upper member a and then
below the lower member a³, and after it is thus passed through it is wound around
the said lower member beyond the loop, then passing over the said upper member
and out through the loop in the opposite direction, that is to say below the mem-
ber as shown. The said strand is thus formed in a kind of twisted loop 2.
the ends of which cross each other and pass through the loop a², a³, in opposito
directions.
As shown in Figures 3 and 4, the relation of the twisted loop 60 to the simple
loop may be somewhat modified without materially affecting the result. In this
instance the strand 610 which corresponds to the strand b Figures 1 and 2, passes
into and out of the loop in the strand a which corresponds to the strand a, at the
same side of the body of the loop, the said strand bio, however, being wound or
twisted around the under member a of the loop, substantially as in the con-
struction shown in Figures 1 and 2.
It is understood of course that the terms above and below are used merely for
convenience and refer to the knot when it is in the position shown in the draw-
ings, it being obvious that the knot will be the same regardless of the position
in which the fabric is placed, the two strands always having the same relation
to each other. Comparing, for example, the different knots shown in Figure 2,
it will be seen that the upper member of the loop in the strand a in the knot
shown in the upper part of the drawing is continuous with the lower member of
the similar loop in the knot shown at the right hand side of the drawing; but
that the member benters the loop in the same way, over the said upper member,
passing below the lower member and around the same beyond the loop, and then
over the upper member and out through the loop under the lower member.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is:-
1. The herein described netting or like structure having the strands thereof
connected by a knot in which knot one strand is formed in a simple loop, the mem-
bers of which cross one above the other; and the other strand passes in through
said loop and winds wholly around the lower member only thereof beyond the
point where the members cross, and then passes out through the loop, substantially
as subscribed.
2. The herein described netting or like structure having the strands thereof
connected by a knot, in which knot one strand is formed in a simple loop, tho
members of which cross one above the other, and the other strand extends through
said loop above the upper member thereof and below the lower member thereof,
being wound around said lower member beyond the loop and then passing out
through said loop above the upper member and below the lower member thereof,
substantially as described..
3. The improved netting constructed substantially as described and shown in
Figures 3 and 4 of the drawings.
