page_text: I WILLIAM GEORGE WHITE of the Polychromatic Simultaneous Printing Company
Limited 153 Queen Victoria Street in the City of London Engineer do hereby
declare the nature of this invention to be as follows:-
In the Specifications of former Patents granted to me No. 14020 in the year 1884
and No. 3047 in the year 1879 is described a system of color printing in which the
printing block is built up of suitably prepared materials containing the various
colors which the design requires and in which the printing block so built up of
coloring materials imparts a portion of its own substance to the fabric to which it
applied.
My present invention has for its object to apply this system of printing to the
dyeing of fabrics in plain colors.
For this purpose I cast the coloring material which is to be applied to the fabric
on to a number of rollers or spindles so as to form a cylindrical coating around
each of them. The rollers I mount in bearings and drive at one speed. The fabric
to be dyed after being mordanted and moistened with a suitable damping liquid
I cause to be led around one of the color rollers so as to bring one surface of the
fabric in contact with that roller then around the next roller so as to bring the
other surface of the fabric in contact with that roller and so on for as many color
rollers as are employed. I ensure that the whole surface of the fabric shall be
brought into contact with the surface of each roller by a straight scraper or padded
bar caused to bear against the fabric where it is passing around the roller-these
also give a slight friction to the cloth and rub into it the color which has been
imparted to its surface.
Preferably I range the color rollers in pairs horizontally one pair above the next
pair and so on for as many pairs of rollers as are used. The bearings for the
spindles I carry by brackets which extend out from the two opposite sides of the
end standards of the machine so that when the caps of the bearings are removed
each roller can readily be lifted out of place and a fresh one substituted for it. The
brackets also carry bearing blocks which receive axes formed at the ends of
the presser bars. Each presser bar at its ends has a weighted arm extending
from it which causes the bar to press constantly towards the color roller which it
works with.

page_text: The bearing blocks which carry the presser bars I also make capable of being
moved along the brackets so that as the color rollers wear away the presser bars
may be moved up towards them.
For applying damping liquid to the cloth before it passes on to the color rollers
I emply a finely perforated metal drum mounted horizontally and with the lower
part of its circumference dipping into a trough containing the liquid whilst the
cloth is led over the upper portion of its circumference. The amount of liquid
applied to the cloth is regulated by the speed at which the perforated drum is
revolved.
The cloth after being suitably mordanted is made up into a roll or batched and
placed on a suitable frame at the front of the machine. From the roll it is led off
under and over a pair of fixed horizontal bars to give tension and prevent its being
drawn too easily into the machine-it then passes over the damping drum which is
situated between the roll and the standard which carries the color rollers and from
there it passes first under the back color roller of the lower pair of color rollers
around this roller and then under and around the front roller of the pair next it is
led around the second pair of color rollers taking the same course around them and
60 on for as many pairs of color rollers as are used. From the last color roller the
cloth is led between and around nipping rollers which are revolved at the speed
required for drawing the cloth forwards through the machine and after passing
these rollers it is rolled or batched on to a roller at the back of the machine.
The roll of cloth when taken from the machine may afterwards be steamed and
treated in any way which may be requisite according to the nature of the coloring
material which has been applied.

that Purpose.
I, WILLIAM GEORGE WHITE of the Polychromatic Simultaneous Printing Company
Limited 153 Queen Victoria Street in the City of London Engineer 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
In the Specifications of former Patents granted to me No. 14020 in the year
1884 and No. 3047 in the year 1879 is described a system of color printing in
which the printing block is built up of suitably prepared materials containing the
various colors which the design requires and in which the printing block so built
up of coloring materials imparts a portion of its own substance to the fabric to
which it is applied.
My present invention has for its object to apply this system of printing to the
dyeing of fabrics in plain colors.
For this purpose I cast the coloring material which is to be applied to the fabric
on to a number of rollers or spindles so as to form a cylindrical coating around
each of them. The rollers I mount in bearings and drive at one speed. The fabric
to be dyed after being mordanted and moistened with a suitable damping liquid I
cause to be led around one of the color rollers so as to bring one surface of the
fabric in contact with that roller then around the next roller so as to bring the
other surface of the fabric in contact with that roller and so on for as many color
rollers as are employed. I ensure that the whole surface of the fabric shall be
brought into contact with the surface of each roller by a straight scraper or padded
bar caused to bear against the fabric where it is passing around the roller-these
also give a slight friction to the cloth and rub into it the color which has been
imparted to its surface.
Preferably I range the color rollers in pairs horizontally one pair above the next
pair and so on for as many pairs of rollers as are used. The bearings for the
spindles I carry by brackets which extend out from the two opposite sides of the
end standards of the machine so that when the caps of the bearings are removed
each roller can readily be lifted out of place and a fresh one substituted for it.
The brackets also carry bearing blocks which receive axes formed at the ends of
the presser bars. Each presser bar at its ends has a weighted arm extending
from it which causes the bar to press constantly towards the color roller which it
works with.
The bearing blocks which carry the presser bars I also make capable of being
шoved along the brackets so that as the color rollers wear away the presser barg
may be moved up towards them.
For applying damping liquid to the cloth before it passes on to the color rollers
I employ a finely perforated metal drum mounted horizontally and with the lower
part of its circumference dipping into a trough containing the liquid whilst the
cloth is led over the upper portion of its circumference. The amount of liquid
applied to the cloth is regulated by the speed at which the perforated drum is
revolved.

placed on a suitable frame at the front of the machine. From the roll it is led off
under and over a pair of fixed horizontal bars to give tension and prevent its being

cloth is led between and around nipping rollers which are revolved at the speed
required for drawing the cloth forwards through the machine and after passing
these rollers it is rolled or batched on to a roller at the back of the machine.
The roll of cloth when taken from the machine may afterwards be steamed and
treated in any way which may be requisite according to the nature of the coloring
material which has been applied.
Figure 1 of the drawings hereunto annexed is a side elevation and Figure 2 an
end elevation of apparatus constructed as above described. AAAA are two pairs
of spindles covered with a cylindrical coating of the coloring material.
B is the fabric led around these color rollers as shown so as to bring one of its
surfaces into contact with one roller of each pair and the other of its surfaces into
contact with the other roller of the pair-C C are scrapers or rubbers by which the
fabric is pressed against the color rollers-they are pressed towards the color rollers
by weights C' on arms affixed to the ends of the axes which carry the rubbers.
D are brackets extending out from two opposite sides of the main frame and
carrying the spindles of the color rollers A as above explained-E are the bearings
of the axes which carry the rubbers and which can be moved inwards along the
brackets as the color rollers wear.
F is the perforated damping roller for applying damping liquid to the cloth before
it is brought into contact with the color rollers. G is the trough into which it
dips B is the roll from which the fabric B is drawn-H H are the bars under and
over which the fabric is led to give tension.
II are nipping rollers between which the fabric is conducted after it has passed
beyond the color rollers-K is a roller on to which the cloth is wound when it has
passed the nipping rollers I.
The way in which the color rollers A. the damping roller G, and the rollers I are
driven is clearly shewn in the drawing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. In the dyeing of fabrics in plain colors the applying the coloring material
to the fabric by means of rollers covered with a solid coating of the material
substantially as described.
2. The dyeing of fabrics substantially by the means described.
3. The combination of apparatus substantially as described to be used in the
dyeing of fabrics.
