PROVISIONAL SPECIFICATION.
An Improved Soap Powder.
I WILLIAM WRIGHT of Fairfield Road, Droylsden in the County of Lancaster,
Manufacturing Chemist, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to produce an improved soap powder which is
intended principally for domestic use but the same may also be used in bleach
works and for other purposes. The invention consists in the combination in suitable
proportions of ordinary soap reduced to powder and what is known as concentrated
soda which is or should be pure soda, with little or no caustic adulteration, and
as nearly as possible deprived of all moisture.
In making my improved soap powder 1 take about equal quantities of the
ordinary bar soap and of this concentrated soda and feed them into a machine for
which Letters Patent No. 3660 were granted to me and Thomas Bintliff bearing
date the 17th of September 1878.
The ingredients are treated in this machine until the soap is reduced to powder
and thoroughly mixed mechanically with the alkali and the resulting mixture is a
powder which is greatly superior to the ordinary soap powder and is very economi-.
cally produced as no boiling or chemical treatment is required in the mixing
process.
The concentrated soda may if desired be in excess of the soap, there may be even
twice as much of the soda as of the soap, according to the purpose for which it is
intended to be applied.
Dated this 17th day of October 1890

SPECIFICATION.
An Improved Soap Powder.
I WILLIAM WRIGHT of Fairfield Road Droylsden in the County of Lancaster
Manufacturing Chemist 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 of this invention is to produce an improved soap powder which is
intended principally for domestic use, but the same may also be used in bleach
works and for other purposes.
The invention consists in the combination in suitable proportions of ordinary
soap reduced to powder and what is known as concentrated soda, which is or should
be pure soda (carbonate of sodium) with little or no caustic adulteration, and as
nearly as possible deprived of all moisture.
In making my improved soap powder I take about equal quantities of the
ordinary bar soap and of this concentrated soda and feed them into a machine for
which Letters Patent No. 3360 were granted to me and Thomas Bintliff bearing
date the 17th day of September 1878.
The ingredients are treated in this machine, or in any other similar apparatus
until the soap is reduced to powder and thoroughly mixed mechanically with the
alkali, and the resulting mixture is a powder which is greatly superior in many
respects to the ordinary soap powder, and is very economically produced as no
boiling evaporation or chemical treatment is required in the mixing process.

page_text: The concentrated soda may if required be in excess of the soap; there may even
be twice as much of the soda as of the soap according to the purpose for which it
is intended to be applied.
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
The improved soap powder formed by the combination of common bar soap
with concentrated soda reduced to powder and mixed together by mechanical
means without boiling evaporation or chemical treatment substantially in the manner
and for the purposes hereinbefore particularly described.
Dated this 14th day of July 1891.
