PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Bag or Washing Blue.
I RICHARD RIPLEY, of Blandford Works, Blandford Street, Liverpool, in the
County of Lancaster, Blue and Black Lead Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object a bag blue as it is generally termed, that is, a
cake of, or powdered, blue fixed in a bag which is tied round with a string or
otherwise. My invention while having all the advantages of the ordinary bag blue
will avoid the defect so objected to in the latter, that it is liable to dissolve with
too great rapidity, or that lumps are liable to fall into the water. By my invention
a nearly uniform amount of blue can be mixed with the water, without having to
touch the pigment.
My invention consists essentially in the employment of a piece of cardboard
which forms a holder for the blue. Thus it may consist of a tube with both ends
open, into which the blue is placed and forms a receptacle therefor, the ends being
enclosed by the bag which is tied round with string, or otherwise, at one end. By
giving the bag blue a longitudinal motion in the water, the water passes through
the ends of the tube and carries out with it in solution, or otherwise, a quantity of
the pigment or powder.
The tube may be made of any other suitable material instead of cardboard, such
as wood, zinc, tinned iron and the like.
If the pulp used in forming the cardboard be mixed with a solution of resin or
other material insoluble in water, there is an advantage, as the tube is less liable
to soften with use. The tube may be perforated if desired to enable the blue to be
more readily dissolved. If desired the sides of the tube may be joined with a
mixture of glue and resin or other cheap cement incapable of dissolving in water.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Bag or Washing Blue.
1, RICHARD RIPLEY, of Blandford Works, Blandford Street, Liverpool in the
County of Lancaster, Blue and Black Lead Manufacturer, 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:-
This invention has for its object a bag blue as it is generally termed, that is, a
cake of, or powdered, blue fixed in a bag which is tied round with a string or
otherwise.
My invention, while having all the advantages of the ordinary bag blue, will
avoid the defects so objected to in the latter, that it is liable to dissolve with too
great rapidity, or that lumps are liable to fall into the water. By my invention, a
nearly uniform amount of blue can be mixed with the water, without having to
touch the pigment.
My invention consists essentially in the employment of a piece of cardboard
which forms a holder for the blue. Thus it may consist of a tube with both ends
open, into which the blue is placed and which forms a receptacle therefor, the ends
being enclosed by the bag, which is tied round with string, or otherwise, at one end.
By giving the bag blue a lougitudinal motion in the water, the water passes

page_text: through the ends of the tube, and carries out with it, in solution or otherwise, a
quantity of the pigment or powder.
The tube may be made of any other suitable material instead of cardboard, such
as wood, zinc, tinned iron and the like.
If the pulp used in forming the cardboard be mixed with a solution of resin or
other material insoluble in water, there is an advantage, as the tube is less liable to
soften with use. The tube may be perforated, if desired, to enable the blue to be
more readily dissolved. If desired, the sides of the tube may be joined with a
mixture of glue and resin or other cheap cement incapable of dissolving in water.
Referring to the drawings:
Figure 1 shows the "bag" or piece of calico or other fabric, open, with a cake of
blue and the cardboard tube (not closed) surrounding it:
Figure 2, the cake of blue with a perforated unclosed tube loosely surrounding
it and
Figure 3, the finished article.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in "bag" blue which consist in enclosing the blue in a tube
open at the ends and enclosed in a bag or cloth, substantially as and for the
purposes described.
2. The improvement appertaining to bag or washing blue which consists in a
tube capable of sufficiently withstanding the destructive action of the water
enclosing the blue and having its ends closed by porous cloth, whereby the shape
of the package is maintained till the blue is exhausted, the fingers need not come
in contact with solid blue while holding it, and the addition of blue to the water is
more uniform while the blue is being actually employed.
