PROVISIONAL SPECIFICATION.
Improvements in Preparing and Packing Ultramarine for Laundry
Use.
I GERALD WARWICK RAWLINS of Rainhill in the County of Lancaster, Manu-
facturer, do hereby declare the nature of this invention to be as follows:
The object is to so treat ultramarine that is produced and maintained in a more fit
condition for use in the laundry, than has heretofore been the case, whilst it is at the
same time more readily available in the required quantities without waste.
My invention consists essentially in conducting the manufacture of ultramarine
substantially in the usual manner until the stage were pressing or otherwise extracting
moisture and drying takes place, here I subject the liquid ultramarine to the action of
a centrifugal machine or to apparatus which extracts only sufficient moisture to
reduce the said liquid ultramarine to semi-fluid consistency in which condition to
preserve it from atmospheric influences it is enclosed in collapsible capsules, or
equivalent convenient receptacles. By the above means the ultramarine is obtained
in its strongest and most effective condition and such condition is preserved intact
when it reaches the hands of the consumer and is used.
Under a inodification of my invention ultramarine may be first dried or caked and
afterwards reduced to the required fluidity before being enclosed in the capsules or
other receptacles but not so advantageously.
A further improvement consists in adding to the fluid ultramarine before it is
enclosed in the capsules a substance or substances adapted to produce a glaze or
stiffening effect on the finished articles from the laundry.

COMPLETE SPECIFICATION.
Improvements in Preparing and Packing Ultramarine for Laundry
Use.
I GERALD WARWICK RAWLINS of Rainhill in the County of Lancaster Manu-
facturer 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 object is to so treat ultramarine that it is produced and maintained in a more
fit condition for use in the laundry than has heretofore been the case, whilst it is at
the same time more readily available in the required quantities without waste.
My invention consists essentially in conducting the manufacture of ultramarine
substantially in the usual manner until the stage where pressing or otherwise
extracting moisture and drying takes place, here I subject the liquid ultramarine to
the action of a centrifugal machine or to apparatus which extracts only sufficient
moisture to re.luce the said liquid ultramarine to semifluid consistency in which
condition to preserve it from atmospheric influences it is enclosed in collapsible
capsules or equivalent convenient receptacles.
By the above means the ultramarine is obtained in its strongest and most effective
condition and such condition is preserved intact when it reaches the hands of the
consumer and is used.
A further improvement consists in adding to semifluid ultramarine however
prepared before it is enclosed in the capsules or receptacles, a substance or substances

page_text: adapted to produce a glaze or stiffening effect on the finished articles from the laundry
and also to prevent the ultramarine from freezing, drying or decoinposing. Substances
suitable for producing a glaze or stiffening effect are borax, starch and like substances
used in proportions varying with the effect desired to be obtained. Substances
suitable for preserving the ultramarine in the required condition are common salt,
glycerine or chloride of calcium in solution and like substances in the proportion of
about fifteen parts of the ultramarine to one part of the substance used.
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:-.
i
First. The manufacture and enclosure of ultramarine substantially as set forth.
Second. The combination with semifluid ultramarine of substances acting sub-
stantially in the manner and for the purpose set forth.
Dated the Second day of September 1890.
