IMPROVEMENTS IN THE MANUFACTURE OF SOAP
Year: 1871

page_text: LETTERS PATENT to William Lorberg, of Cricklewood, in the County
of Middlesex, Chemist, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF SOAP."
Sealed the 23rd January 1872, and dated the 27th July 1871.
PROVISIONAL SPECIFICATION left by the said William Lorberg
at the Office of the Commissioners of Patents, with his Petition,
on the 27th July 1871.
I, WILLIAM LORBERG, of Cricklewood, in the County of Middlesex,
Chemist, do hereby declare the nature of the said Invention for " IMPROVE-
MENTS IN THE MANUFACTURE OF SOAP," to be as follows:-
I make a solution of gluten caustic alkali, and thoroughly incor-
porate the same with the soap to the extent of ten per centum, more
or less, which imparts to the soap so treated a great amount of emollient
or softening properties.
The incorporation of gluten with soap is applicable to any kind of
soap, and may be performed during the so-called remelting process or
in the original process of manufacture immediately after saponification
has taken place.

page_text: The solution of gluten I make in the following manner, viz.:-To a
solution of caustic soda or caustic potassa of about 20 degrees Baumé,
I add as much bran or gluten derived from any other source as it will
take up; after some hours' digestion the mass becomes clear and homo-
geneous; I then strain it through a fine sieve or coarse cloth, and of t
* Tall to the moon in the proportion above stated
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Lorberg in the Great Seal Patent Office
on the 26th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LORBERG, of Cricklewood, in the County of Middlesex, Chemist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of July, in the year
our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Lorberg, Her special licence
that I, the said William Lorberg, my executors, administrators, and
assigns, or such others as I, the said William Lorberg, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time, and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF SOAP," upon the condition (amongst others) that I,
the said William Lorberg, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Lorberg, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement :-

page_text: I make a solution of gluten in caustic alkali, and thoroughly incor-
porate the same with the soap to the extent of ten per centum, more
or less, which imparts to the soap so treated a great amount of emollient
or softening properties.
The incorporation of gluten with soap is applicable to any kind of
soap, and may be performed during the so called remelting process or
in the original process of manufacture immediately after saponification
has taken place.
The solution of gluten I make in the following manner, namely:-To
a solution of caustic soda or caustic potassa of about twenty degrees
"Baumé " I add as much bran or gluten derived from any other source
as it will take up. After some hours' digestion the mass becomes clear
and homogeneous; I then strain it through a fine sieve or coarse cloth,
and of this liquid I add to the soap in the proportion above stated.
I have in practice found it preferable to employ a dilute solution of
gluten, and I therefore either add four or five times its quantity of water
to the strong solution of gluten prepared as above set forth, or prepare
the solution in the following proportions, namely :-To about a gallon
of water I add a pint of solution of caustic soda or caustic potassa
of from thirty to forty degrees "Baumé," and stir into this mixture
three or four handfulls of bran, or half a pound, more or less, of gluten
obtained in the manufacture of starch or otherwise. After two or three
hours' digestion with occasional agitation I strain through canvass or
coarse cloth or a fine wire sieve. The filtrate will be of a gelatinous
or mucilaginous nature, and may be used at once or be kept for an
almost indefinite period without material deterioration. Soap will take
thirty per cent. or even more of this liquid without becoming soft.
If other materials are to be mixed with the soap it is advantageous
to add the gluten first, as it assists in combining the other ingredients,
but this order of succession is not material.
Having now described and ascertained the nature of my said Inven-
tion, and in what manner the same is or may be performed, I would
have it distinctly understood that I do not limit myself to the precise
relative proportions above given, as such may be varied according to
the quality of the ingredients and of the soap to be manufactured, and
that what I claim as secured to me by the hercin-before in part recited

page_text: Letters Patent is, the use of bran or other gluten in the manufacture
of soap when prepared and applied substantially as herein-before set
forth.
In witness whereof, I, the said William Lorberg, have hereunto
set my hand and scal, this Twenty-sixth day of January, in the
year of our Lord One thousand eight hundred and seventy-two.
