We ROBERT BARRINGER, ISAAC HENRY WALLIS and WALTER BARRINGER, all of
the firm Barringer & Brown of Rock Valley Mills Mansfield, in the County of
Nottingham Mustard, Blue and Black Lead Manufacturers do hereby declare the
nature of the said invention, to be as follows:-
-
Laundry blue is now mostly prepared in a solid state and is generally placed
when used in a bag of flannel or other suitable material to retain heavy settling
ingredients which would otherwise produce blotches of blue color or uneven
tinting or coloring and the object of our invention is to dispense with the straining
bag and to prepare the blue color or dye in a more convenient form so that it may
be applied for Laundry purposes to produce any desired and uniform delicate tint
on linen and other cloths with certainty and without fear of blotches or of irregular
tint in color or loss by waste and while obtaining these advantages in use our
improved Laundry blue is in a most convenient form for the market and for
packing and transport.
Our invention consists in combining any suitable blue color or dye, with an
adhesive material which will readily dissolve in water, and we then apply such
compound blue color and adhesive material to a suitable absorbent material such as
paper or woven or other suitable textile material, by any convenient means, and
the material so prepared when dry, is put up in rolls or is cut into leaves or sheets
of any convenient size or shape, and then made up in envelopes books or other
convenient form for the market and for use for Laundry purposes.
As an example it may be explained that we dissolve the finest Ultramarine Blue,
Indigo or Prussian Blue, or if preferred Analine or chemically prepared liquid blue,
and then mix the blue, with adhesive substance such as Gelatine, Gum Arabic
or dextrine dissolved in water or dissolved in the liquid used for dissolving the
color.
The proportions are or may be about as follows four eighths of blue color, one
eighth of adhesive material, and three eighths of water.
The mixture or compound liquid thus formed is applied to the absorbent paper
or other textile material by brushes, rollers, or by immersion of the paper or other

page_text: material in the compound, by hand or by arrangements of machinery driven by
motive power.
When our "Azuline" Laundry blue leaves, are used for Laundry purposes, they
are immersed in water which dissolves the compound from the leaves, until the
desired color is imparted to the water and a part of a leaf or one or more leaves
are used to produce the desired effect, and according to the quantity of water to be
colored, by this means experience will readily show the quantity required to
produce uniformly and with certainty the desired tint.
