PROVISIONAL SPECIFICATION.
"Improvements in the Manufacture of Detergent Fluids."
I, RODERICK STEWART of 231 St. Eonan Terrace, Cumbernauld Road, in the
County of the City of Glasgow, Brush Manufacturer, do hereby declare the
nature of my Invention to be as follows:-
This Invention has reference to and comprises improvements in detergent fluids
and in their manufacture, such fluids being of great service for cleansing and
bleaching clothes and cloth fabrics and enabling such operations to be carried
on with great case and efficiency without the necessity of rubbing or the appli-
cation of friction. These fluids are also very useful for removing stains from
furniture, woodwork and the like, or cleaning the hands or the skin fromi
tenacious matter such as tar, paint and such like.
According to the improvements of this Invention the preparation of detergent
fluids is carried on as follows:-Quick lime is first slaked by the application
of moisture and reduced to a powdered state from which all foreign matter is
as far as possible removed. Slaked lime in the proportion of say one pound to
five quarts of water with a quantity of Carbonate of Soda about equal to that of
the lime added is placed in a suitable boiler and boiled until the ebullition ceases
and the liquid becomes clear, when the quantity of water is usually reduced by
about one fifth. The whole is then allowed to stand until all or the bulk of the
solid particles are precipitated, when the clear liquid is drawn off and if necessary
carefully strained or filtered. Alum and pearlash are also mixed in the approxi-
mate proportion of one ounce of alum to one pound of pearlash and placed in
a vessel preferably a stoneware jar which is corked or otherwise hermetically
closed. This mixture is allowed to stand for some time until the whole liquifies
when it is carefully strained.
The lime liquid first described and the fluid pearlash mixture are then mixed
together it may be in equal or variable quantities the mixture being again
boiled until the liquid becomes clear. The resulting detergent fluid when cool
is then ready for storing in jars or bottles or in any convenient manner.
For some purposes a small quantity of borax is added to the fluid.
For washing clothes a tea cupful of the fluid is added to the water in an
ordinary washing copper or boiler at a temperature slightly below the boiling
point. The clothes are placed in the boiler and boiled for about half an hour
when they will be found ready for rinsing without requiring to be rubbed.
When linen or the like is stained or extra soiled such may be previously steeped
in water and the stains or soiled parts rubbed with a little soap before being boiled
as described.

I, RODERICK STEWART, of 231 St. Eonan Terrace, Cumbernauld Road, in the
County of the City of Glasgow, Brush Manufacturer, do hereby declare the nature
of my Invention and in what manner the same is to be performed to be particularly
described and ascertained, in and by the following statement, that is to say:-

of moisture and reduced to a powdered state from which all foreign matter is
as far as possible removed. Slaked lime in the proportion of say one pound to
five quarts of water or for some purposes the quantity of water may be
increased with a quantity of Carbonate of Soda about equal to that of
the lime added is placed in a suitable boiler and boiled until the ebullition ceases
and the liquid becomes clear, when the quantity of water is usually reduced by
about one fifth. The whole is then allowed to stand until all or the bulk of
the solid articles are precipitated, when the clear liquid is drawn off and if neces-
sary carefully strained or filtered. Alum and pearlash are also mixed in the ap-
proximate proportion of one ounce of alum to one pound of pearlash and placed in
a vessel preferably a stoneware jar which is corked or otherwise hermetically
closed. This mixture is allowed to stand for some time until the whole liquifies
when it is carefully strained.
The lime liquid first described and the fluid pearlash mixture are then mixed
together it may be in equal or variable quantities the mixture being again
boiled until the liquid becomes clear. The resulting detergent fluid when cool
is then ready for storing in jars or bottles or in any convenient manner.
For some purposes a small quantity of borax it may be four ounces is added
to the fluid.
For washing clothes a tea cupful of the fluid is added to the water in an
ordinary washing copper or boiler at a temperature slightly below the boiling
point. The clothes are placed in the boiler and boiled for about half an hour
when they will be found ready for rinsing without requiring to be rubbed.
When linen or the like is stained or extra soiled such may be previously steeped
in water and the stains or soiled parts rubbed with a little soap before being boiled
as described.
When used for bleaching purposes such as for gray cloth or brown linen the
fabrics may be steeped in an acid bath, boiled with the improved detergent fluid
and after steeped in a chemick bath which may be prepared from chloride of lime
and acetic acid.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what 4
I claim is: :-
1. The preparation and use of the detergent fluid all substantially as herein

page_text: 2. A detergent fluid prepared from slaked lime, carbonate of soda, alum, and
peal ash, all substantially as described.
