PROVISIONAL SPECIFICATION.
Improvements in or relating to Laundry Blue.
I, JOSEPH KNOWLES of 121 Clarence Street, Bolton in the County of
Lancaster, Manager, do hereby declare the nature of my said invention to be as
follows:-
This invention refers to improvements in or relating to laundry blue, and has for
its object that of constructing and pressing blocks of laundry blue in such a form as
to give an increased dissolving surface, which will allow of the same being pressed
considerably harder than hitherto, by which blue will be given off when agitated
in water-more gradually, thereby lessening the tendency to specking. To effect
this I construct or press the blocks of laundry blue in any suitable form, such as,
round or circular, oval, square, oblong, or of other polygonal forms, with the outer
surface or face of the same corrugated, fluted, recessed, or ribbed. The corruga-
tions, flutes, recesses, or ribs can be of any suitable form, such as, convexed, con-
caved, angular, or others that will produce or increase the outer surface of the block
of bluc.

1, JOSEPH KNOWLES of 121 Clarence Street, Bolton in the County of
Lancaster, Manager, do hereby declare the nature of my said 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 refers to improvements in or relating to laundry blue, and has for
its object that of constructing and pressing blocks of laundry blue in such a form as
to give an increased dissolving surface, which will allow of the same being pressed
considerably harder than hitherto, by which blue will be given off when agitated
in water-more gradually, thereby lessening the tendency to specking. To effect
this construct or press the blocks of laundry blue in any suitable form, such as,
round or circular, oval, square, oblong, or of other polygonal forms, with the outer
surface or face of the same corrugated, fluted, recessed, or ribbed. The corruga-
tions, flutes, recesses, or ribs can be of any suitable form, such as, convexed, concaved,
angular, or others that will produce or increase the outer surface of the block of
blue.

Fig. 15 is a plan of a square block of laundry blue with concaved or fluted outer
surface.
Fig. 16 is a plan of a square block of laundry blue with ribbed and recessed outer
surface.
Fig. 17 is a plan of a hexagonal block of laundry blue with convexed or corrugated
outer surface.
Fig. 18 is a plan of a hexagonal block of laundry blue with angular corrugated
outer surface.
Fig. 19 is a plan of a pentagonal block of laundry blue with concaved or fluted
outer surface, and
Fig. 20 is a plan of an octagonal block of laundry blue with ribbed and recessed
outer surface.
In all the figures the same letters are employed to indicate corresponding
parts.
A is intended to represent a pressed block of laundry blue of various forms with
the outer surface provided with the corrugations B to give an increased dissolving
surface, which will allow of the said blocks of blue being pressed considerably
harder than hitherto, by which blue will be given off when agitated in water-
more gradually, thereby lessening the tendency to specking, which is of vital
importance in laundry operations.
The outer surface of a block of laundry blue can be increased for the purpose
specified by making the corrugations B convexed as in Figs. 1, 2, 9, 13, and 17:
concaved or fluted as in Figs. 5, 6, 11, 15, and 19; angular as in Figs. 3, 4, 10,
14, and 18 or with the recesses as in Figs. 7, 8, 12, 16 and 20.
The said corrugations B, whether convexed, concaved or fluted, angular or ribbed
can be of any desired number and size according to the dimensions of the block of
blue. The corrugations B can be of equal and unequal sizes as in Fig. 17.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the game is to be performed, I declare that what I
claim is :-
Constructing pressed blocks of laundry blue with their outer surfaces provided
with corrugations of convexed, concaved or fluted, angular, or recessed forms for
the purpose of increasing the dissolving surface to allow of the blue being given off
more gradually and lessen the tendency to specking, substantially as described.
