Improvements Wire Lattices.
A communication to me from THE METALLTUCH-FABRIK "DÜREN," of Düren,
Rhenish Prussia, in the Empire of Germany.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, 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, and accompanying drawing, that is to say :-
The present invention has for its object a novel method of making wire lattico
work, by which the movement against each other of the wires forming the lattice
is prevented by means of rings through which the wires pass at the points where
they cross, and are not only prevented from moving in the plane of the lattice,
but are also securely held together so as to prevent movement at right angles to
the said plane. The accompanying drawing is in illustration of the invention.
It is especially applicable to wire lattice work with rectangular meshes, as shewn
in Figure 1. Each angle of this lattice is formed of two wires a and b crossing
each other at right angles.
At these points rings c, bent into a more or less saddle-like shape, are fitted, as
shewn in Figure 2, and Figures 3 to 5.
Figure 3 is a plan, Figure 4 a section on the line a-x, and Figure 5 a section
on the line y-y, of Figure 3.
In this ring c the wires. a, b are so united, that they cross each other and, for
example, the wire a lies above the wire b, in the curves of the ring, as shewn in
Figure 2, and in Figures 6 to 8 of which Figure 6 is a plan, Figures 7 and 8
sections on the lines - and y-yl Figure 6, respectively.
The ringe is then hammered or pressed back until it is nearly or quite flat, as
shewn in Figures 9 and 10, which are also sections on the lines x-x and y'-y¹
respectively.
In this way the wires a and b are bulged out in the parts lying in the ring, so
that by their connection with the latter any axial movement of the wires is
prevented, and the locking and holding of one wire against the other also serves
to prevent any movement between them at right angles to the plane of the lattice.
Figure 11 is a plan shewing how, instead of two, three wires a, b, and may
cross each other at each junction of the meshes. In this case the ring c is of course
bent more widely to receive the wires.
A similar modification may be used, if more than three wires cross each other.
Instead of a circular ring c, a ring of any other suitable shape (such as quadri-
lateral or the like) may be used to hold the wires in the way described. Some
such shapes are illustrated in Figures 12 to 20.
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 :-
A novel method of making wire lattice work, in which the shifting of the
wires a, b forming the lattice at the points where they cross each other is prevented,
by passing them through a circular or other ring so bent, as iliustrated in Figure 2,
that one of the wires presses against one side of the bent ring, and the other wire

page_text: against the other side, the wires being then bent by partially orientirely flattening
down the ring by hammering or pressing, so that the wires are prevented from
shifting in any direction, substantially as described and illustrated.
