Improvements in the Manufacture of Blue Colouring Matter for
Laundry Bleaching and other Purposes.
We MILES WILLIAMS of Bootle Liverpool in the county of Lancaster Manufacturing
Chemist and JESSE ASCOUGH of Handsworth in the county of Stafford Agent, do
hereby declare the nature of this invention to be as follows:-
The purpose and object of this invention is the manufacture of antiseptic Soluble
Blue for Laundry uses, Bleaching, domestic and other purposes, for improving and
colouring cotton, wool, linen, clothing, paper, sugar chrystals, the production of
writing inks and other articles and consists of a combination of farina, sago flour, rice
flour, starch, china clay or other similar base with with soda biboras, borax, boracic
acid, or other boron compound and aniline dyes or other dyestuffs; solutions of indigo,
Prussian blue, or ultramarine made by treating them with acids and when necessary
neutralising with an alkili to be hereafter more fully described.
These blues are not intended for pigments and this invention differs materially in
this respect from the application for Provisional protection made by the above named
Miles Williams and Nod. 382 9th Jany. 1889. The blue salts thus formed are
perfectly soluble in water and do not deposit by standing. An addition of glycerine
glucose sugar and gummy matter may be intermixed if desired.
In preparing the blue I make a solution of aniline blue with water and glycerine
and add to it varying proportions of farina separately, or conjointly with any of the
before named similar substances or all of them, and thoroughly mix to an uniform
mass into.a paste by grinding or otherwise.
I then add borax or other boron compound by preference in fine powder to the
until it becomes granulated, after which it can be pressed for thumb, square or other
shaped blue, dried, granulated, or ground and seived for powder blue. The starchy
matter may be omitted if desired or I make a solution of indigo with a mineral or
other acid and heat it up to about 145 % Fahr. until it assumes a violet blue colour.
I then neutralize the acid with an alkili, afterwards, adding water to form a solution
and then intermix it with the other, ingredients and borax, or other boron, compound,
or, I take Prussian blue and treat it with an acid to render it soluble in water, or
ultramarine may be substituted.
Each of these blues may be used together or separately in combination with borax
or other boron compound, starch, china clay, gum, and similar substances. The object
being to obtain a brilliant blue perfectly soluble in water from aniline dyes, indigo,
Prussian, blue, ultramarine or other source with an antiseptic base of borax, boracic
acid or other boron compound.

Improvements in the Manufacture of Blue Colouring Matter for
Laundry, Bleaching, and other Purposes.
We MILES WILLIAMS of Bootle Liverpool in the county of Lancaster Manufacturing
Chemist and JESSE ASCOUGH of Handsworth in the of Stafford, Agent, 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:
The purpose and object of this invention is the manufacture of antiseptic soluble

page_text: blue for Laundry, Bleaching, and domestic purposes; for improving and colouring
cotton, wool, linen clothing, paper, sugar and other chrystals the production of writing
inks, and other articles and consists of a combination of farina, sago flour, rice flour,
starch, china clay, or other suitable base with soda biboras, borax, boracic acid, or
other boron compound and aniline dye or other dyestuffs, solutions of indigo,
Prussian blue, or ultramarine, made by treating such analine dye, indigo, Prussian
blue, or ultramarine with oxalic, sulphuric or other acid and when necessary
neutralising with soda potash or other alkali. An addition of glycerine, glucose,
sugar, or gummy matter may be intermixed if desired.
Blues thus made are not intended for pigments, and this invention differs materially
in this respect from that claimed under the Letters Patent No. 382 granted to the
above named Miles Williams and bearing date 9th January 1889. In preparing the
blue we make a solution of aniline dye with water and glycerine and add to it varying
proportions of farina separately or conjointly with any of the before named substances,
or all of them, and thoroughly mix to an uniform mass or paste, by grinding or other-
wise. We then add borax or other boron compound by preference in fine powder to
the mixture until it becomes granulated, after which it can be pressed for thumb,
square, or other shaped blue or dried, ground, and seived for powder blue. Or we
make a solution of indigo with a mineral or other acid, and heat it up to about 145%
Fahr. until it assumes a voilet blue colour. We then neutralize the acid with sodium
carbonate or other alkali, afterwards adding water to form a solution, or we take
Prussian blue and treat it with oxalic or other acid to render it soluble in water and
then intermix it with the other ingredients and the borax or other boron compound.
Each of these blues may be used separately or two or more in combination with
borax or other boron compound, starch, china clay, gum, and other suitable substances,
the object being to obtain a brilliant blue soluble in water from aniline dyes, indigo,
Prussian blue, ultramarine or other source, with an antiseptic base of borax, boracic
acid, or other boron compound.
In giving an example of the manufacture we wish it to be distinctly under-
stood that we do not confine ourselves to the proportions herein named. Nor to
the ingredients specified except in so far as relating to borax, boracic acid or other
boron compound. For instance we can take 4 parts of aniline blue, 8 parts of
Prussian or indigo blue (after treating them with acid and alkali to render them
soluble) adding gradually 70 parts of water, 300 parts starchy matter, china clay
or other suitable substance or a mixture of them and 100 parts of soda biboras,
borax, boracic acid, or other boron compound and thoroughly intermix them so
as to form a granulated paste, powder, or liquid antiseptic blue.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is-
The manufacture of antiseptic blue in granulated, crude, lump, block, dry,
powder, liquid or other form by combining borax borate of sodium, boracite,
calcium borate tincal, boracic acid, or other boron compound with aniline,
Prussian blue, indigo or ultramarine, or other dyestuff substantially as herein set
forth.
