page_text: LETTERS PATENT to Maximilian Zingler, of 19, Buckland Crescent,
Belsize Park, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IR TREATING ANILINE AND OTHER DYES TO PREPARE THEM
ZAD SE IN DING PRINTING AND COLORING.”
PROVISIONAL SPECIFICATION left by the said Maximilian Zingler at
the Office of the Commissioners of Patents, with his Petition, on
the 30th October 1874.
I, MAXIMILIAN ZINGLER, of 19, Buckland Crescent, Belsize Park, in
the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN TREATING ANILINE AND OTHER DYES TO
PREPARE THEM FOR USE IN DYEING, PRINTING, AND COLORING," to be as
follows:-
This Invention has for its object improvements in treating aniline and
other dyes to prepare them for use in dyeing, printing, and colouring.
For these purposes the aniline, salts, or other colouring matter are
dissolved in the Patent copal varnish, as described in the Specification
of my former Patent, dated 9th April 1874 No. 1239,.and in order to

page_text: make it fit for printing and colouring I add to this lac dye, oleaginous or
fatty matter, or both.
For the purpose of dyeing fabrics I dissolve the lac dyes in the solvent
described in my former Patent, as mentioned above. This solvent
consists of bi-sulphide of carbon, together with either or all of the
following, viz., camphine, turpentine, methylated spirit, benzol, rectified
petroleum, which I vary according to the nature of the dyeing matter.
This solution is suitable for use as a dye for any fabrics, some of which
will have to be prepared with the requisite mordants.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said Maximilian Zingler in the Great Seal Patent
Office on the 30th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MAXIMILIAN
ZINGLER, of 19, Buckland Crescent, Belsize Park, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of October, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Maximilian Zingler, Her
special license that I, the said Maximilian Zingler, my executors,
administrators, and assigns, or such others as I, the said Maximilian
Zingler, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN TREATING ANILINE AND OTHER DYES TO PREPARE
THEM FOR USE IN DYEING, PRINTING, AND COLORING," upon the condition
(amongst others) that I, the said Maximilian Zingler, my exccutors
or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Maximilian Zingler, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:—
This Invention has for its object improvements in treating aniline and
other dyes to prepare them for use in dyeing, printing, and coloring.
With the varnish described in the Specification of my Patent, No. 1239
in the year 1874, or with the similar varnish made with eupion, and
described in the Specification of my Patent No. 3758 in the present
year, I combine aniline or other dyes. I first dissolve the aniline dye in
any spirit or distilled cupion, as described; I prefer methylated spirit,
and to every 100 lbs. of spirit I put ½ to 1 lb. of aniline dye. Some of
these dyes, the black dye especially, dissolve more freely if a small
quantity of muriatic acid, say, from 2 to 5 per cent., be added to the
dye before the spirit is mixed with it. To the red aniline dyes I similarly
add a small quantity of sulphuric acid. Other dyes I dissolve in a
similar manner. The quantity I employ I regulató according to the
depth of tint I desire to obtain. When the dye is dissolved I thoroughly
mix it with the varnish.
To make the color homogeneous I add 5 per cent. of any of the baryta
salts.
Aniline and other dyes thus compounded with the varnishes above
mentioned are very suitable for dyeing ivory, bone, leather, and such like
materials for printing woven fabrics, and for coloring wood, metal, paper,
paper hangings, and the like.
What I claim is, the treatment of aniline and other dyes to prepare
them for use in dyeing, printing, and coloring, substantially as
described.
