Improvements in Colouring, Sizing, and otherwise Treating Paper,
and in Apparatus therefor, also applicable for Filling and
Treating Woven Fabrics.
I, JOHN MURRAY CAMPBELL, of Waterside, Disley, in the County of Chester,
Paper Stainer, do hereby declare the nature of this invention to be as follows:-.
My invention is particularly applicable to machines for colouring papers the
object being to spread the colour more evenly than heretofore and at the same
time to dispense with the usual brushes employed for this purpose.
In applying my improvements to such a machine I employ a main drum also a
colour box and sieve cloth as usual, the cloth passes from the roller near the
colour roller to a roller placed at any convenient distance from the colour box;
the colour box and one sieve cloth roller are mounted in a frame so that they can
be readily moved toward or from the centre of the main drum.
The paper to be coloured is wound upon a roller from which it passes over a
guide roller to the main drum which in this case is driven positively and drives
preferably by an expanding pulley the axle of the fixed or upper sieve roller; the
sieve cloth and the drum are both driven preferably in the same direction and at
suitable speeds for the work to be done.
By moving the colour box and lower sieve roller nearer to or farther from the
drum a greater or smaller surface of contact between the paper to be coloured
and the sieve cloth can be readily effected; the colour is fed onto the sieve cloth
in the usual manner and I propose to employ a "doctor or brush to remove the
surplus colour before it reaches the paper.
"
In colouring a hard or smooth surface paper the frame with the colour box and
lower sieve roller would be brought near the drum in order to give a large contact
of surface between the sieve cloth and paper to be coloured and further if
required the speed of the sieve cloth is reduced by the expanding pulleys or other
means in order that the paper may receive sufficient friction to take an even surface
of colour.
In colouring a soft or rough paper it would be desirable to remove the colour
box &c., further from the drum and increase the speed of the sieve cloth in order
to reduce the friction on the paper.
The paper after being coloured, sized, varnished or otherwise treated as gummed
on the machine is passed on to a drying machine. In treating papers which
require to be subsequently burnished a jigger brush may be applied to act upon the
paper in the machine after it has been coloured.
My improved machine may be applied to the operations known as backing and
filling and otherwise treating woven fabrics.

what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
My invention is particularly applicable to machines for colouring papers the
object being to spread the colour more evenly than heretofore and at the same
time to dispense with the usual brushes employed for this purpose.
In applying my improvements to such a machine I employ a main drum or
roller also a colour box and sieve cloth as usual; the sieve cloth passes from the
roller or rollers near the colour roller to a roller placed at any convenient distance
from the colour box; the colour box with its rollers and the upper sieve cloth
roller are mounted so that they can be readily moved toward or from the centre
of the main drum.
And in order that my invention may be fully understood I will describe the
same with reference to the accompanying diagram of a machine for colouring
papers arranged according to my improvements.
The paper a to be coloured is wound upon a roller supported in bearings in
standards c from which it passes over a guide roller d to the main drum or roller e
which in this case is driven positively and drives preferably by expanding pulleys
or change wheels (not shown) the axle of the upper sieve roller f; the sieve
cloth g and the drum e are both driven preferably in the same direction and at
suitable speeds for the work to be done. The sieve cloth g passes from the
upper roller which might be fixed but is preferably adjustable to two rollers h
supported by the colour box i which also carries the colour furnishing roller ; and
is adjustable to and from the main drum e.
By moving the colour box i and lower sieve rollers h or the upper sieve roller f
nearer to or farther from the drum e, a greater or smaller surface of contact
between the paper a to be coloured and the sieve cloth g can be readily effected;
the colour is fed on to the sieve cloth in the usual manner and 1 propose to employ
a "doctor" or brush say at the point X to remove the surplus colour before it
reaches the paper.
In colouring a hard or smooth surface paper the frame with the colour box i
with the lower sieve rollers h or the upper sieve roller would be brought near
the drum e in order to give a large contact of surface between the sieve cloth g
and paper a to be coloured and further if required the speed of the sieve cloth g
is reduced by the expanding pulleys, or other means, in order that the paper a
may receive sufficient friction to take an even surface of colour. The amount of
colour can thus be varied by increasing or reducing the speed of the sieve cloth g
as required.
In colouring a soft or rough paper it would be desirable to remove the colour
box i, &c., further from the drum to reduce the surface contact of the sieve cloth
and increase the speed of the sieve cloth in order to reduce the friction on the
paper.
It will be understood that the colour box i may be used as a receptacle for
size varnish or other material for treating the paper, and also that other fabrics
besides paper may be similarly treated in this machine for example my improved
machine may be applied to the operations known as backing and filling and
otherwise treating woven fabrics.
The paper a or other fabric after being coloured, sized varnished, gummed or
otherwise treated on the machine is passed on to a drying machine. In treating
papers which require to be subsequently burnished a jigger brush may be applied
to act upon the paper in the machine after it has been coloured.
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. Applying colour size, varnish, gum or other material to paper or other
fabrics by means of the frictional contact between a travelling sieve cloth and the

page_text: said paper or other fabric stretched upon a revolving drum, the sieve cloth being
supplied with colour or other material and being adjustable to or from the axis
of the drum substantially as and for the purposes specified.
2. The combined arrangement of parts substantially as and for the purposes
herein described with reference to the accompanying diagram.
