William
We, WILLIAM MATHWIN ANGUS, Wire Worker, trading as
Mountain & Sons, Trafalgar Wire Works, in the City and County of Newcastle-
upon-Tync, and GEORGE FOSTER RYAN, Foreman at said Trafalgar Works,
do hereby declare the nature of said 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 has reference to an improved construction of straight lattice wire
work by which the wire is more economically applied, as to the material required,
and as to the cost of making, whilst securing adequate strength and durability.
Straight lattice wire work as ordinarily made consists of vertical and horizontal
wires crossing each other at right angles being laced or lapped with fine wire to
keep it together and form the "mesh."
According to our invention we make the straight lattice of a single series of
wires arranged preferably vertically forming the "mesh" (i.e. the distance between
the wires) and interlace at suitable intervals, two wires crossing the series at
right angles. Where these cross wires are interlaced the main or "mesh" wires
are formed with corrugations alternately raised and sunk and into these similar
corrugations, on the crossing wires, fit in such manner that the distance between
the main wires is fixed and interlocked by said cross wires without the use of fine
wire, laced or lapped at the intersections, as ordinarily required which binding
wire is quickly corroded and destroyed. Thus a stronger and more durable lattice
work is made, with the same strength of material as the ordinary straight
lattice work and with a considerable economy in cost both of material and
workmanship.

A A A &c. are the series of main wires with corrugations at A', A', A' &c. to
receive similar corrugations B', B' B' &c. on the cross wires B, B, B &c. which
interlace the main wires and by the corrugations interlock both the main and
cross wires so that neither can move out of position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
The method of making straight lattice wire work by which the wires forming
the "mesh" are interlaced at suitable intervals with two wires crossing them at
right angles with corrugations which engage with similar corrugations in the
"mesh" wires in such manner as to interlock and to fix the distance between the
"mesh" wires and also between the cross wires substantially as described and
with the objects herein before set forth.
