IMPROVEMENTS IN LIQUID SOAP AND IN THE MANUFACTURE OF THE SAME.
Year: 1877

page_text: LETTERS PATENT to Jonathan Scharr, of Bradford, in the County of York, for
the Invention of "IMPROVEMENTS IN LIQUID SOAP AND IN THE MANUFACTURE
OF THE SAME.

Sealed the 13th July 1877, and dated the 4th April 1877.
PROVISIONAL SPECIFICATION left by the said Jonathan Scharr at the Office
of the Commissioners of Patents on the 4th April 1877.

LIQUID SOAP AND IN THE MANUFACTURE OF THE SAME."
"IMPROVEMENTS IN
By the use of this liquid soap for scouring wool, yarn, woollen, or other woven
or felted substances, the wool or other goods are much improved both in brightness
and touch.
The manufacture of this soap is very simple, and can be prepared for use in
about two hours.
To produce one hundred gallons of liquid soap I begin with about sixty-six
gallons of water, and add while it is cold the following:
From say about twelve to twenty-one pounds of linseed and two pounds of
farina starch; these articles are placed in some suitable receptacle, and boiled by
preference by the injection of steam for fifteen or twenty minutes; afterwards the
following ingredients are added:-
About thirteen pounds of calcined potash.
One hundred and sixty-two pounds of refined soda ash (fifty degrees
free from caustic).
Twelve pounds of resin (virgin or good amber).
Four pounds of borax.
Three pounds of sal amoniac.
Two gallons of oleine oil.
Three quarts of spirits of turpentine.
Two quarts of liquid ammonia, eight hundred and eighty degrees of
strength, mixed with from four to six quarts of water previous to
being added to the other ingredients.
The whole of the ingredients are then boiled from one hour and a half (Baume's
bydrometer, showing thirteen degrees with the liquid at boiling point). The liquid,

page_text: after being boiled, is passed through a sieve so as to extract the thick part; then it
is ready for use.
The thick part that remains in the sieve is used for a second boiling.
And to produce one hundred gallons for a second boiling I begin with about
sixty-six gallons of water, and then add the thick part caught in the sieve from the
first boiling and two pounds of farina starch; the steam is then turned on and the
following ingredients added:-
About eight pounds of calcined potash.
One hundred and fifty-four pounds of refined soda ash (fifty degrees

"IMPROVEMENTS IN
By the use of this liquid soap for scouring wool, yarn, woollen, or other woven
or felted substances, the wool or other goods are much improved both in brightness
and touch.
The manufacture of this soap is very simple, and can be prepared for use in about
two hours.
To produce about one hundred gallons of liquid soap, I begin with about sixty-
six gallons of water and add while it is cold the following:-
About from say twelve to twenty-one pounds of linseed and two pounds of
farina starch; these articles are placed in some suitable receptacle and boiled by
preference by the injection of steam for fifteen to twenty minutes, and afterwards
the following ingredient are added :-
About thirteen pounds of calcined potash.
One hundred and sixty-two pounds refined soda ash (fifty
degrees free from caustic).
Twelve pounds of resin (virgin or good amber).
Four pounds of borax.
Three pounds of sal ammoniac.
Two pounds of oleine oil.
Three quarts of spirits of turpentine.
Two quarts of liquid ammonia (eight hundred and eighty
degrees of strength, mixed with from four to six quarts of
water previous to being added to the other ingredients).
The whole of the ingredients are then boiled for one hour and a half (Baume's
hydrometer, showing thirteen degrees with the liquid at boiling point). The liquid,

page_text: after being boiled, is passed through a sieve so as to extract the thick part; then it
is ready for use.
The thick part that remains in the sieve is used for a second boiling.
And to produce one hundred gallons for a second boiling, I begin with about
sixty-six gallons of water, and then add the thick part caught in the sieve from the
first boiling and two pounds of farina starch; the steam is then turned on and the
following ingredients added:-
About eight pounds of calcined potaslı.
One hundred and fifty-four pounds of refined soda ash (fifty
dogroes free from caustic).
Seven pounds of rosin (virgin or good amber).
Three pounds of borax.
Two pounds of sal ammoniac.
One and a half gallons of oleine oil.
Two quarts of spirits of turpentine.
Two quarts of liquid ammonia (eight hundred and eighty
degrees of strength, mixed with from four to six quarts of
water previous to being added to the other ingredients).
The whole of the ingredients are then boiled for two hours (Baume's hydrometer,
to shew thirteen degrees with the liquid at the boiling point), and after being run
through a sieve is ready for use.
The thick part which remains in the sieve after this boiling is useless.
In some cases I employ Iceland moss or seaweed combined with linseed, or either
separately.
For producing a boiling heat, in all cases steam is injected or used by preference.
I would have it understood that I do not limit myself to the exact proportions
given, which are taken as an approximate, and the quantity of each ingredient
may be varied in accordance with the nature or quality of the material, or the
purpose for which it is required, but what I claim is, the manufacture of liquid soap
substantially as herein set forth.
In witness whereof, I, the said Jonathan Scharr, have hereunto set my hand
and seal, this First day of October, in the year of our Lord One thousand
eight hundred and seventy-seven.
