page_text: I CHARLES HOLLIDAY of the Firm of Read Holliday and Sons of Huddersfield
in the County of York Manufacturing Chemist seek leave to ainend the specifi-
cation of Letters Patent, No. 2946 of 1882, as shown in red ink in the copy of the
original specification hereunto annexed, that is to say at Page 3 line 9 Insert at the
beginning of the line the words "Having now described the nature of my said
invention and the manner in which the same should be performed I would have it
understood that I do not claim the processes of producing azo colors on cotton or
other vegetable fibre disclosed in the specifications of the Letters Patent granted
to Thomas Holliday and Robert Holliday dated July 6th 1880 and numbered 2757
and the Letters Patent granted to Thomas Holliday dated April 14th 1881 and
numbered 1638 nor any part of such processes."
My reasons for making this amendment are as follows:-To prevent any
misunderstanding as to the matters intended to be claimed in the specification of
the said Letters Patent No 2946 of 1882.
Dated this 13th day of July 1885.
In the Matter of the Application made by Charles Holliday for leave to amend
the Specification of Letters Patent No 2946 of 1882:

page_text: LETTERS PATENT to Charles Holliday of the firm of Read Holliday and
Sons of Huddersfield in the County of York, Manufacturing Chemists for
an Invention of "IMPROVEMENTS IN PRODUCING AZO-COLORS ON COTTON OR
OTHER VEGETABLE FIBRE.

PROVISIONAL SPECIFICATION left by the said Charles Holliday at the
Office of the Commissioners of Patents on the 21st June 1882.
CHARLES HOLLIDAY of the firm of Read Holliday and Sons of Huddersfield in
the County of York Manufacturing Chemists " IMPROVEMENTS IN PRODUCING
AZO COLORS ON COTTON OR OTHER VEGETABLE FIBRE
"
In effecting my improvements I first oil the cotton or other vegetable fibre by
any suitable known process, such as is employed when oiling fibre for dyeing with
alizarine or for Turkey Red. I then proceed to form on such oiled fibre the colors
made by the combination of diazo or diazo azo compounds with the napthols or
other phenolic bodies.
As an example of the manner in which any invention may be carried into effect-
Cotton yarn inay be steeped in a solution of (say) 10 per centum sulphonated oil
neutralised with soda: the superfluous oil in the yarn is then wrung out and the
yarn dried, and after the oil is sufficiently oxidised on the fibre I proceed to wash
off in a weak solution of carbonate of soda: these operations being repeated if
necessary; I then dry the yarn, then wash off in water and again dry the yarn;
the fibre is then ready for the formation thereon of an azo color.
To effect this formation of color the fibre thus prepared may be passed through
or steeped in a 1 per centum solution of napthol in hot water, and when cooled
then worked in a weak solution of (say) the diazo or amido azo compound, prepared
or produced from bodies such as Saffranine, Aniline, toluidine xylidine, Alpha- and
Beta-napthylamine, Amido-azo-benzol, amido azo toluol, amido azo xylol, amido
azo napthaline, or other similar bodies, or mixtures of them, according to the
particular color or shade of color desired to be obtained. This solution being
prepared slightly acid and before using neutralised by carbonates such as are
hereinafter mentioned in order to secure a neutral solution.
The neutralization of the solution of diazo or amido azo compound may be effected
by a carbonate such as bi-carbonate or carbonate of Calcium Barytes, Barium,
Strontium, or other suitable carbonate capable of forming a neutral solution the
color thus being formed in combination with the oxidised oil as well as the fibre
without the aid of an alkali after dyeing, being requisite. The particulars may be
varied,
The solutions of diazo or amido azo compounds may be employed either hot or
cold according to circumstances the heat being applied after the color has been
developed on the fibre, or otherwise,

mentioned
