NATHANIEL BRADLEY of Chapman Street Hulme Manchester County of
Lancaster England. "THE MANUFACTURE OF A DRY, ANTISEPTIC NON-HYGRO-
SCOPIC POWDER FROM A LIQUID EXTRACT OF SAPONIN SUITABLE AND CONVENIENT
FOR COMMERCIAL PURPOSES. TO BE USED IN THE WASHING AND SCOURING OF
SILKS AND FOR PRESERVING AND GIVING FINISH TO FLAT LIQUIDS."
This Invention consists in a process by which a liquid extract of saponin from
any vegetable product containing saponin is converted into a dry powder which
will keep dry on exposure to the atmosphere, thus rendering the extract more easy
of transit and more convenient to store, to sell and to use in the scouring of silks
and for giving head, finish and soundness to flat beverages. In 1877 A.D. 1 made
and sold a dry extract of saponin for giving head to flat beverages and for use in
Scouring silk and other fabrics, and I was the first to prepare and offer for salo
such a powder in this country.
.
That powder or any other dry pure extract of saponin is hygroscopic and must
be kept in air-tight vessels, for on exposure to the atmosphere it absorbs moisture,
becomes sticky and pasty and forms a mass difficult to dissolvo and troublesome
to use.

page_text: But by this Invention I have counteracted the hygroscopic properties of saponin
when in powder and have made an extract of saponin which remains as a dry
powder however long exposed to the atmosphere and is therefore more suitable
and convenient for commercial purposes since it can be packed without dete-
rioration in paper bags and be kept in open vessels and further it is so prepared
that it possesses antiseptic properties and when added to beverages helps to keep
them sound and bright.
My process is as follows:-
The liquid extract of saponin is first evaporated to the consistency of syrup.
The heat is then lowered and so kept until the extract is thoroughly dry. In
this state it is combined with a mixture of carbonate of magnesia, lime salts and
dry tartaric acid or other vegetable acids and the antiseptics bi-borate of soda and
sulphite of soda. These ingredients not only counteract the hygroscopic properties
of the pure extract but when actually in contact with a liquid or beverage the
soluble sulphite of soda chemically acts upon the insoluble carbonate of magnesia
and the free acid so assists that a clear wholesome solution of all the substances is
obtained.
This powder of my exclusive manufacture may therefore be used, and is used
with advantage to give head to flat beverages and to preserve them sound and
bright..
I also add to this dry, compound, sugar dextrin and rice-cereal or pulso-flour for
uso in the washing and scouring of silks.
I do not intend to compound at one time all the ingredients mentioned but to
vary them so as to make the dry powder suit the circumstance whether it be for
the bleaching and scouring of pure white silks where for instance the sulphites
are most valuable or the scouring of coloured or dyod silks. where the sulphites
are not serviceable or the heading and preserving of flat beverages.

NATHANIEL BRADLEY of Chapman Street Hulme Manchester in the County of
Lancaster England "THE MANUFACTURE OF A DRY ANTISEPTIC NON-HYGROSCOPIC
POWDER FROM A LIQUID EXTRACT OF SAPONIN SUITABLE AND CONVENIENT FOR
COMMERCIAL PURPOSES TO BE USED IN THE WASHING AND SCOURING OF SILKS AND FOR
PRESERVING AND GIVING FINISH TO FLAT LIQUIDS."
This invention consists in a process by which a liquid extract of Saponin from any
product containing Saponin is converted into a dry powder which will keep dry on
exposure to the atmosphere thus rendering the extract more easy of transit and more
convenient to store to sell and to use in the securing of silks, and for giving head or
finish and soundness to flat beverages.
In one thousand eight hundred and seventy seven I made and sold a dry extract of
Saponin for giving head to flat beverages and for use in scouring silk and other
fabrics and I was the first to prepare and offer for sale such a powder in this country.
That powder or any other dry pure extract of Saponin is hygroscopic and must be
kept in air tight vessels, for on exposure to the atmosphere it absorbs moisture
becomes sticky and pasty and forms a mass difficult to dissolvo and troublesome
to uso.
But by this invention I have counteracted the hygroscopic properties of Saponin
when in powder and have made an extract of Saponin which remains as a dry powder
however long exposed to the atmosphere; and is therefore more suitable and con-
venient for commercial purposes since it can be packed without deterioration in paper
bags and be kept in opon vessels. and Further it is so prepared that it possesses
antiseptic properties and when added to beverages helps to keep them sound and
bright.
My process is as follows:—
The liquid extract of Saponin is first evaporated to the consistency of syrup. The
heat is then lowered until the extract is perfectly dry. In this state it is combined
with a mixture of Carbonate of Magnesia Lime Salts and dry Tartaric acid or other
known suitable vegetable acids and the antiseptic Biborate of Soda and Sulphite of
Soda. These ingredients not only counteract the hygroscopic properties of the pure
extract but when actually in contact with a liquid or beverage the soluble sulphite of
Soda chemically acts upon the insoluble carbonate of Magnesia and the free acid so
assists that a clear wholesome solution of all the substances is obtained.
This powder of my exclusive manufacture may therefore be used, and is used, with
advantage to give head to flat beverages and to preserve them sound and bright.
I also add to this dry compound engar destrin and rice cerent or pulse flour for use
in the washing and scouring of silke.
I do not intend to compound at one time all the ingredients mentioned, but to vary
them so as to make the dry powder suit the circumstance, whether it be for the
bleaching and scouring of pure white silks where for instance the sulphites are
most valuable or the scouring of coloured or dyed silks where the sulphites are not
serviceable or the heading and preserving of flat beverages.

page_text: In some cases I shall also add the ingredients in the liquid form to produce
an antiseptic Anid which will give lead to flat liquids and will of itself keep
sound without the admixture of Alcohol.
I wish it to be understood that what is claimed and intended to be secured by the
Patent is the preparation of a dry powder from a liquid extract of Saponin and the
combination of this liquid extruct of Saponin to impart to it keeping properties
when in the liquid state, and the combination of the dry powder us herein described
so as to produce a non-hygroscopic antiseptic powder as described or a preservative
foam or antiseptic frothing powder which can be packed with advantage in paper
bags and kept in open vessels without deterioration therefore more suitable for
commercial purposes. also wish it to be understood that what is claimed and
intended to be secured is the use of this antiseptic liquid and the dry powder in
the securing and finishing of silks and other fabrics and for use in giving head
and finish to fat liquids and for keeping them sound and bright and for the purposes
hereinbefore set forth und described.
In witness whereof I the said Nathaniel Bradley have hereto set my hand
and seal this first day of April in the year of Our Lord One thousand
eight hundred and eighty two
