PROVISIONAL SPECIFICATION.
Improvements in and relating to the Manufacture of Woven
Wire Cloth.
I, WILLIAM HENRY JOHNSON, of the firm of Richard Johnson Clapham and Morris,
24 and 26 Lever Street, Manchester, in the County of Lancaster, Wire Manufacturer,
do hereby declare the nature of this invention to be as follows:-
:-
My invention consists in certain improvements in and relating to the manufacture
of woven wire cloth such as that used by paper makers and the chief object of my
invention is to produce wire cloth which shall be stronger and more durable than
ordinary wire cloth and further to obviate the difficulty of unravelling hitherto
experienced in weaving with a twisted wire warp.
Prior to my present invention it has been customary to employ a wire warp com-
posed of say five single wires or more or less twisted together at one operation and
when weaving wire cloth with such a warp in the event of one of the wires of the
strand being cut there is nothing to prevent it from unravelling.
I therefore now propose to employ a warp composed of any suitable number of
strands which have been twisted together in two operations. Thus for example I
twist two or more wires together to form a strand and then twist together in a second
operation two or more strands thus produced and so form my improved wire warp.
1 have stated that I produced my improved wire warp in two operations but by
special machinery it is possible at one operation to simultaneously twist the wires into
strands and twist the strands together in a manner similar to that now employed in
making certain classes of wire ropes.
I also have an improvement in the wire weft which improvement consists in
employing a twisted wire weft whether produced by twisting wires together in the
ordinary way or in a similar manner to that above described for my improved
wire warp.
The improved wire warp and the improved wire weft may be used either alone
separately or both together in combination when weaving wire cloth.

Improvements in and relating to the Manufacture of Woven
Wire Cloth.
I, WILLIAM HENRY JOHNSON, of the firm of Richard Johnson Clapham and Morris,
24 and 26 Lever Street, Manchester, in the County of Lancaster, Wire Manufacturer,
do hereby declare the nature of this said 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 consists in certain improvements in and relating to the manufacture
of woven wire cloth such as that used by paper makers and the chief object of my
invention is to produce wire cloth which shall be stronger and more durable than
ordinary wire cloth and further to obviate the difficulty of unravelling hitherto
experienced in weaving with a twisted wire warp.
Prior to my present invention it has been customary when weaving wire cloth to employ
wire warp composed of a number say five single wires, or more or less, twisted
together at one operation to form a strand, and when weaving wire cloth with such
a

page_text: warp in the event of one of the wires of the strand being cut or broken there is
nothing to prevent it from unravelling and so causing a permanent injury to the
fabric.
To overcome this serious defect therefore I now propose to employ a warp composed
of any suitable number of strands which have been twisted together in two operations.
Thus for example I first twist two or more wires together to form a strand and in like
manner produce as many strands as are required and then twist together in a
second operation two or more strands thus produced and so form my improved
wire warp.
I have stated that I have produced my improved wire warp in two operations but
by special machinery it is possible at one operation to simultaneously twist the several
series of wires into strands and twist the series of strands together in a manner similar
to that now employed in making certain classes of wire ropes.
I have also an improvement in the wire weft which improvement consists in employing
a twisted wire weft whether produced by twisting wires together in the ordinary way
or in a similar manner to that above described for my improved wire warp.
The improved wire warp and the improved wire weft may be used either alone
separately or both together in combination when weaving wire cloth.
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 :
1. In the manufacture of wire cloth the use and application of an improved
wire warp composed of a series of strands twisted together each strand being composed
of two or more wires twisted together substantially as and for the purpose herein
described.
2. In the manufacture of wire cloth the use and application of an inproved
wire weft whether produced by twisting single wires together or by first twisting
the wires into strands and then twisting the strands together into weft substantially as
herein described.
3. In the manufacture of wire cloth the combination with an improved wire warp
produced as hereinbefore described, of an improved weft composed of twisted single
wires or twisted strands substantially as specified.
