page_text: LETTERS PATENT to Henry Bock Binko,. of. 41, Oleveland Road,,
Southgate Road, Islington, in the County of Middlesex, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE AND APPLICATION OF
INDIGO, CARMINE, AND OTHER COLORING MATTERS AND. BLEACHING AGENTS."
PROVISIONAL SPECIFICATION left by the said Henry Bock Binko
at the Office of the Commissioners of Patents, with his Petition,
on the 12th February 1869.
I, HENRY BOCK BINKO, of 41, Oleveland Road, Southgate Road,
Islington, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE AND APPLICATION
OF INDIGO, CARMINE, AND OTHER COLORING MATTERS AND BLEACHING AGENIS," to
be as follows:-
I dissolve finely ground and sifted indigo of the best quality in
sulphuric acid, and allow it to rest for three days. I then add water in
which is steeped cow or goat hair, and' boil the whole until it appears
green. After twenty-four hours the hair is removed and rinsed in water
until it becomes blue; it is then boiled in a solution of potash for an
hour, strained, and evaporated, to half its bulk, and allowed to rest
1281

page_text: thirty-six hours, when it separates into two fluids.
The supernatant
thin liquor is used for writing ink, after the addition of a little gum.
The lower or heavier liquor is a solution of indigo-carmine, to which
some glycerine is added while in a shallow vessel. The coloring matter
of this solution when absorbed by bibulous paper, dried and pressed, may
at any time be communicated to any liquid required by the simple
immersion of a portion of it. In this form I propose, to use it for
laundry purposes instead of the old form of solid blue.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bock Binko, in the Great Seal Patent
Office on the 15th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BOCK BINKO, of.41, Cleveland Road, Southgate Road, Islington, in the
County of Middlesex, send greeting.

page_text: NOW KNOW YE, that I, the said Henry Bock Binko, 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:-
I take indigo of the best quality, and after it is finely ground and
sifted I dissolve it in acid in the proportion of 3 lbs. of acid to 1 lb. of
indigo, and allow the mixture to stand for three days, after which I add
to every pound of the above indigo 20 lbs. of water and 5 lbs. of goat or.
cow hair, boiling the whole 3 hours, or until it becomes of a greenish
hue. This is then allowed to remain 24 hours standing.
.
The
The hair is
then taken out and washed in clear cold water until a beautiful blue
color appears.
I then put the hair in 10 gallons of water and boil it,
and whilst boiling add potash in the proportion of 10 lbs. of potash to
1 lb. of indigo, thus rendering the indigo solution free from acid.
whole is then strained and evaporated to half its bulk, and allowed to
remain 36 hours standing. Two fluids are now formed; the upper thin
portion, when mixed with some size or gum, can be used as a blue
writing ink; the lower portion, containing the real indigo-carmine, is
then put in a wide but shallow vessel, and some glycerine added thereto
in the proportion of a quarter of an ounce of glycerine to one pound of
indigo. I now dip unsized paper or other vegetable fibre in the vessel
containing the solution, and in a few minutes the paper will have taken
up the coloring matter, or it may be imparted to the paper by soft
brushes. The paper is now dried and pressed, and is then ready for use
as a coloring and bleaching agent, for use in the laundry, and for manu-
facturing purposes.
For the manufacture of a description of printing
ink 10 per cent. of powdered starch is added to the fluid.
In witness whereof; I, the said Henry Bock Binko, have hereunto
set my hand and seal, this
day of
One thousand
Witness to signature,

Agent to the Patentee.
