I, JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of said Invention for IMPROVEMENTS IN
WIRE CLOTHS FOR USE IN THE MANUFACTURE OF PAPER which Invention has
been communicated to me from abroad by Messieurs Blanchet Brothers and
Kléber of Rives (Isère) in the Republic of France to be as follows:-
This Invention relating to the manufacture of paper consists in the employment
of a wire cloth prepared as hereinafter described which enables either plain laid or
ripped paper or laid or ripped and shaded water marked paper to be obtained the
said water marks being placed in any desired position relatively to the ground
wires. These cloths are applicable to the manufacture of continuous or machine
made paper as well as to the manufacture of or hand made paper. In the manu-
facture of continuous machine made paper either the dandy roll is covered with
the specially prepared cloth or an endless apron of the said cloth is employed in
place of the endless sheet or apron ordinarily employed In the manufacture of
hand made paper the prepared cloth is placed in the moulds The said cloth is
provided with parallel wires which in place of being connected and secured in
position by binders placed at intervals as heretofore practised form an integral part
of a very fine wire fabric which constitutes a species of ground or canvas and
maintains the wires permanently at the proper distance apart and effectually
prevents the whole fabric from becoming disturbed.
These cloths may also be employed in combination with wires secured by
binders in the usual manner.
The depressions and elevations necessary to produce a shaded or other water
mark or design in the paper are or may be formed by suitable dies or formers on
this cloth or fabric. These designs or water marks are crossed by the ribs or
ridges formed in the paper by the parallel wires.
Dated this 1st day of January 1885.

Gentleman do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN WIRE CLOTHS FOR USE IN THE MANUFACTURE OF PAPER" which Invention
has been communicated to me from abroad by Messrs Blanchet Brothers and
Kléber of Rives (Isère) in the Republic of France and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This Invention relating to the manufacture for and use in the making of paper
of wire cloth prepared as hereinafter described which enables either plain laid or
ripped paper or laid or ripped and shaded water marked paper to be obtained the
said water marks being placed in any desired position relatively to the ground
wires. These cloths are applicable to the manufacture of continuous or machine
made paper as well as to the manufacture of vat or hand made paper. In the
manufacture of continuous machine made paper either the dandy roll is covered
with the specially prepared cloth or an endless web of the said cloth is employed
in place of the ordinary endless sheet or apron. In the manufacture of hand made
paper the prepared cloth is placed in the moulds which may be worked by hand or
mechanically.
The said cloth is provided with parallel wires of suitable thickness at equal
distances apart and these wires in place of being connected and secured in position
by binders placed at intervals as heretofore practised form an integral part of a
woven fabric of very fine wire which constitutes a species of ground or canvas
and maintains the aforesaid parallel wires permanently at the proper distance
apart and effectually prevents the whole fabric from becoming disturbed. These
cloths may also be employed in combination with wires secured in the usual
manner.
The depressions and elevations necessary to produce a shaded or other water
mark or design in the paper are or may be formed by suitable dies or formers on
this cloth or fabric. These shaded or other designs or water marks are crossed by
the ribs or ridges formed by the parallel wires.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
First For the making of paper the manufacture and use of wire cloths pro-
vided with parallel wires secured in position by interweaving them with finer
wires forming the body or main portion of the cloth so that the said parallel wires
form an integral part of the woven cloth or fabric produced (whether or not
there be used in combination therewith other wires or devices secured to the said
cloth or fabric in the manner hitherto customary) substantially as hereinbefore
described.

facture and use of wire cloths constituted as claimed by the preceding claiming
clause and embossed to give the required designs or water marks in the paper
substantially as herein before described.
