Marbled, Variegated, or like Papers.
I, OSCAR HAROLD STONE, of The Grange, Erdington, near the City of Birming-
ham, Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates to a new process of coloring paper, and has for its object
the production of variegated or mottled colored papers in two or more or a variety
of colors, which coloring is performed during the time that the paper is in the
state of pulp and in the process of manufacture, or in other words, whilst the paper
pulp is on the machine.
The said process consists in applying by sprinkling or otherwise, dyes or other
coloring matters to the pulp, preferably at the "wet" end of the machine, although
my invention is equally applicable to the application of dyes or colors to the pulp
at the "dry" end of the machine.
According to one process, the pulp, after being manipulated in the ordinary
way, is served onto the machine, and whilst it is being carried forward the surface
is sprinkled with two or more colors or dyes differing from the color of the pulp,
which sprinklings of dyes, on coming in contact with the moist pulp or paper
in a wet state, both sink into the same diffuse or disperse themselves in
varying degrees within and over the parts of the material being colored.
Thus, for example, I take paper pulp having a grey body color, and whilst still
on the machine, I serve or sprinkle parts of the surface with dark green dye or
other color, the spots of which, after falling, diffuse or disperse themselves over
and into the material, thereby producing a variegated, cloudy, mottled or marbled
paper, which, after leaving the machine, is calendered or glazed or otherwise
finished by well-known processes.
Where two colors are required in the mottling, then the pulp or paper is or
may be either sprinkled with two colored dyes at the same time, or a second color
is served immediately after the first, and a third color may be applied immediately
after the second, and so on, according to the number of colors which the paper
is required to be served with.
Instead of sprinkling on the dye or color, the same may be served by dabbing
the surface with a soft brush, sponge or the like charged with the dye or color,
and instead of coloring the paper in irregular mottlings or cloudings, the dye
may be applied in lines, zig-zags or other patterns either by brushes or other servers,
or by mechanical means.
As another modification, instead of applying the dye or coloring matter in a
liquid state, I wish it to be understood that the dye may be in the form of powder
sprinkled or applied to either the wet or dry end of the machine. I prefer to
employ aniline dies as they disseminate and sink into the pulp or paper more

the process of manufacture.

A New or Improved Process for the Manufacture of Coloured,
Marbled, Variegated, or like Papers.
I, OSCAR HAROLD STONE, of The Grange, Erdington, near the City of Birming
ham, Manufacturer, 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: —
This invention relates to a new process of coloring paper, and has for its object
the production of variegated or mottled colored papers in two or more or a variety
of colora, which coloring is performed during the time that the paper is in the
state of pulp and in the process of manufacture, or in other words, whilst the paper
pulp is on the machine.
The said process consists in applying, by sprinkling or otherwise, dyes or other
coloring matters to the pulp, preferably at the "wet" end of the machine, although
my invention is equally applicable to the application of dyes or colors to the pulp
at the "dry" end of the machine.
"
According to one process, the pulp, after being manipulated in the ordinary
way, is served onto the machine, and whilst it is being carried forward the surface
is sprinkled with two or more colors or dyes differing from the color of the pulp,
which sprinklings of dyes, on coming in contact with the moist pulp or paper
in a wet state both sink into the same and diffuse or disperse themselves in
varying degrees within and over the parts of the material being coloured.
Thus, for example, I take paper pulp having a grey body color, and whilst still
on the machine, I serve or sprinkle parts of the surface with dark green dye or
other color, the spots of which, after falling, diffuse or disperse themselves over
and into the material, thereby producing a variegated, cloudy, mottled or marbled
paper, which, after leaving the machine, is calendered or glazed or otherwise
finished by well-known processes.
Where two colors are required in the mottling, then the pulp or paper is or
may be either sprinkled with two colored dyes at the same time, or a second color
is served immediately after the first, and a third color may be applied immediately
after the second, and so on, according to the number of colors which the paper
is required to be served with.
Instead of sprinkling on the dye or color, which I may effect by means of a
rose attached to a syringe or receptacle, or other means the same may be served
by dabbing the surface with a soft brush, sponge or the like charged with the
dye or color, and instead of coloring the paper in irregular mottlings or cloudings
the dye may be applied in lines, zig-zags or other patterns either by brushes or
other servers, or by mechanical means.
As another modification, instead of applying the dye or coloring matter in a
liquid state, I wish it to be understood that the dye may be in the form of powder
sprinkled or applied to the wet end of the machine. I prefer to employ ordinary
aniline dies as they disseminate and sink into the pulp or paper more readily on
coming into contact with the wet or.. moist surface of the material during the

page_text: process of manufacture, and that such dies should be of a strength in accordance
with the tone or depth of the color required to be produced.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
First: The process of producing variegated or mottled colored papers in two
or more or a variety of colors, consisting in applying dyes or coloring matter, by
sprinkling or otherwise, to the paper pulp when on the machine, and preferably
at the "wet" end which said colors sink into diffuse or spread over and through
the body of the said pulp, substantially as described and set forth.
Secondly: A new mottled or variegated colored paper in which the dye or
coloring matter is diffused and spread over, into and through the body of the
same, substantially as described and set forth.
