Renfrew, North Britain, Esquire, for an Invention of "IMPROVEMENTS IN
THE PREPARATION OF COLORING AGENTS OR MATERIALS."
PROVISIONAL SPECIFICATION left by the said James Young at the Office
of the Commissioners of Patents on the 20th April 1881.
JAMES YOUNG, the younger, of Kelly, in the County of Renfrew, North Britain,
Esquire. "IMPROVEMENTS IN THE PREPARATION OF COLORING AGENTS OR
MATERIALS."
This Invention relates to improvements in the Inventions for which Letters
Patent were granted to William Robert Lake on or about the 22nd day of October
1879, No. 4299, and to John Henry Johnson on or about the 20th day of January
1880, No. 251, and consists in the preparation of the coloring agents used in the
coloring of fibrous materials in the following manner :-
I prepare the infusorial earth or other color bearing vehicle to be employed by
adding thereto suitable quantities of the colors, the infusorial earth or other vehicle,
and the colors being both in a dry state, and the earth or other vehicle being
bleached or unbleached, I then place the infusorial earth or other vehicle and
coloring matters in a mill, mortar, or other suitable apparatus, and grind the same
together to a fine powder. For colors requiring mordants, I then add a sufficient
quantity of suitable mordant to the mass, and I also add slowly whilst the grinding
process is going on so much non saponifiable, or in some cases saponifiable oil as is
required to render the mass suitable for application to the coloring of cotton, wool,
or other fibrous material, either when the fibrous material is in the unmanufactured
state, or is in the condition of yarn, or when it has been woven into a fabric or in
any other stage of manufacture. The coloring matters so prepared are then ready
for application, as stated in the above mentioned Specifications.
Although I have stated that either saponifiable or non saponifiable oils may be
used, I prefer the use of non saponifiable oils.

JAMES YOUNG, the younger, of Kelly, in the County of Renfrew, North Britain,
Esquire. "IMPROVEMENTS IN THE PREPARATION OF COLORING AGENTS OR
MATERIALS."
My said Invention relates to improvements on the Inventions for which Letters
Patent were granted to William Robert Lake on or about the Twenty second day
of October, One thousand eight hundred and seventy nine, Number 4299, and to
John Henry Johnson on or about the Twentieth day of January, One thousand
eight hundred and eighty, Number 251, and consists in the preparation of the
coloring agents used in the coloring of fibrous materials in the following manner :-
I prepare the infusorial earth or other color bearing vehicle to be employed by
adding thereto suitable quantities of the colors with or without a mordant, the
infusorial earth or other vehicle and the colors being (and mordant when such is
requisite) in a dry state, and the earth or other vehicle being bleached or unbleached.
I then place the infusorial earth or other vehicle and coloring matters in a mill,
mortar, or other suitable apparatus, and grind the same together to an impalpable
powder. I then add slowly whilst the grinding process is going on so much
nonsaponifiable, or in some cases saponifiable oil as is required to render the mass
suitable for application to the coloring of cotton, wool, or other fibrous material,
either when the fibrous material is in the unmanufactured state, or is in the
condition of yarn, or when it has been woven into a fabric or in any other stage of
manufacture.
The coloring matters so prepared are then ready for application, as stated in the
above mentioned Specifications.
Although I have stated that either saponifiable or nonsaponifiable oils may be
used, I prefer the use of nonsaponifiable oils.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is,-
Mixing the prepared coloring matter when in a dry condition with oil in a mill,
mortar, or other grinding apparatus, substantially as hereinbefore described.
In witness whereof, I, the said James Young, the younger, have to this my
Specification set my hand and seal, this Fourteenth day of October, One
thousand eight hundred and eighty one.
