page_text: LETTERS PATENT to Wilhelm Adolf Von Kanig, of Hardinge Street
Islington, in the County of Middlesex, for the Invention of "IMPROVE
MENTS IN THE MANUFACTURE OF STARCH AND COMPOUNDS OF STARCH, AND IN
EXTRACTING GUM, DEXTRINE, AND GRAPE SUGAR THEREPROM."
Sealed the 28th February 1860, and dated the 31st August 1859.
PROVISIONAL SPECIFICATION left by the said Wilhelm Adolf Von Kanig
at the Office of the Commissioners of Patents, with his Petition, on the
31st August 1859.
I, WILHELM ADOLF VON KANIG, of Hardinge Street, Islington, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF STARCH AND COMPOUNDS OF STARCH,
AND IN EXTRACTING GUM, DEXTRINE, AND GRAPE SUGAR THEREFROM," to be
as follows:-
This Invention consists in manufacturing starch in the following manner
and of the following ingredients, that is to say:-I take the sago of commerce,
either whole, in which case it must be ground fine, or I use flour of sago, and
proceed to wash and cleanse it from impurities in cold water, and then mix
therewith a purified solution of chloride of lime, made by dissolving from one
quarter to half a pound of chloride of lime in 112 pints of water, and I stir.
the whole together until well mixed, and leave it to bleach and settle for an
hour or so; the liquid is then separated from the solid portion, and the solid
[Price 8d.]

page_text: residue or starch well washed with cold water until all traces of lime arc
removed therefrom; this residue is then left to dry, and is fit for use. By this
Invention it will be seen that I convert sago into a soluble starch, and can
obtain therefrom, as commonly practised in the manufacture of starch, gum,
dextrine, and grape sugar.
Another feature in this Invention consists in making compounds of starch
by mixing the improved starch with ordinary starch during its manufacture,
by which it is refined and improved, and rendered soluble. I also propose to
combine the improved starch with gum, by which it is rendered useful for
printing and other purposes for which gum is now used.
Another feature in this Invention consists in the use of a solution of chloride
of lime in the manufacture of ordinary starch, for the purpose of separating
the glutten therefrom, and for making soluble starch, and for converting
insoluble starch into soluble starch.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Wilhelm Adolf Von Kanig in the Great Seal Patent Office
on the 29th February 1860).
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILHELM
ADOLF VON KANIG, of Hardinge Street, Islington, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of August, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and graut unto me, the
said Wilhelm Adolf Von Kanig, Her special licence that I, the said
Wilhelm Adolf Vou Kanig, my executors, administrators, and assigus, or such
others as I, the said Wilhelm Adolf Von Kanig, my executors, adminis-
trators, 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 STARCH AND COMPOUNDS
OF STARCH, AND IN EXTRACTING GUM, DEXTRINE, AND GRAPE SUGAR THEREFROM,"
upon the condition (amongst others) that I, the said Wilhelm Adolf Von
Kauig, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe

page_text: and ascertain the nature of tho said Invention, and in whatmanner 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 Wilhelm Adolf Von Kanig, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:-
This Invention consists in manufacturing starch in the following manner
and of the following ingredients, that is to say:-I take the sago of commerce,
either whole, in which case it must be ground fine, or I use flour of sago, and
proceed to wash and cleanse it from impurities in cold water, and then mix
therewith a purified solution of chloride of lime, made by dissolving one pound
of chloride of lime in three gallons of water, and I stir the whole together
until well mixed, and leave it to bleach and settle for three hours, more or
less; the liquid is then separated from the solid portion, and the solid residue
or starch well washed with cold water until all traces of lime are removed
therefrom; this residue is then left to dry, and is fit for use. By this
Invention it will be seen that I convert sago into a soluble starch, and can
obtain therefrom, as commonly practised in the manufacture of starch, gum,
dextrine, and grape sugar.
Another feature in this Invention consists in making compounds of starch
by mixing the improved starch with ordinary starch during its manufacture,
by which it is refined and improved and rendered soluble. I also propose to
combine the improved starch with gum, by which it is rendered useful for
printing and for other purposes for which gum is now used.
Another feature in this Invention consists in the use of a solution of chloride
of lime in the manufacture of ordinary starch, for the purpose of separating
the gluten therefrom, and for making soluble starch, and for converting
insoluble starch into soluble starch.
In order to explain this Invention as completely as possible, I now proceed
to describe the best means I am acquainted with for carrying the same into
practicle effect as follows:-
PROCESSES OF MANUFACTURE.
I take sago or other farinaceous or vegetable substance containing starch,
such as wheat, rice, barley, oats, millet, rye, maize, buck-wheat, peas, beans
potatoes, tapioca, mandioca, and other materials containing starch.
In operating upon the above in their original state, I first steep them in

page_text: water, as commonly practised, or in a weak solution of chlorine, and when
sufficiently softened and crushed to a pulp in the ordinaryway, I then proceed
to mix therewith a purified solution of chloride of lime, composed by mixing
one pound of chloride of lime with about three gallons of water, and steep the
pulp therein for about three hours, more or less, in order to dissolve the gluten
from the starch, and also to make it soluble, and keeping the whole well
stirred during this time, after which the starch may be removed from the pulp
in the ordinary way. I then proceed to remove the impurities and chlorine
from the starch by frequent washings in cold water until the water appears
quite clear, by which I obtain a pure starch soluble in boiling water.
instead of operating with the chlorine in the manner above stated, the starch
may first be extracted from the pulp and afterwards be operated upon withthe
chlorine, as above stated. In operating upon either of the above-mentioned
farinaceous or vegetable substances after they have been reduced to a powder
or flour, I proceed to wash and cleanse them from impurities with cold water
in the usual way; I then add thereto the chlorine solution before-mentioned,
keeping it well stirred for about three hours or more, as before stated. I then
wash it frequently in cold water, as before stated; the result is a purestarch
soluble in boiling water.
Or
To make compounds of starch, 1 take 50 parts of the ordinary starch, and
mix therewith 50 parts of sago, and conduct the remainder of the process in
the manner before described, and thus produce refined and soluble starch.
In manufacturing starch inter.ded to be used by calico printers, I mix with
my first above-mentioned starch a solution of tragacanth gum in the propor-
tion of about three ounces of the solution to every. 112 pounds of thestarch.
Starch manufactured by my improved processes is capable of yielding gum,
dextrine, and grape sugar, which may be obtained in the ordinary manner.
I would here remark, that starch manufactured by my above-mentioned
improved process may either be stoved in the manner commonly practised by
such manufacturers so as to make it flour or powder starch, or it may be
prepared as a damp or semi-fluid starch.
Having now fully described and set forth the nature and object of my said
Invention of "Improvements in the Manufacture of Starch and Compounds
of Starch, and in Extracting Gum, Dextrine, and Grape Sugar therefrom,"
together with the best means I am acquainted with for carrying the same into
practical effect, I hereby declare my Invention to consist in and I claim,
the use of chlorine in and for the manufacture of starch and compounds of
starch, as above stated, and for the purposeof converting insoluble starch into
soluble starch, and for separating the gluten from the starch.

page_text: I also claim the use of chemicals other than chloride of lime possessing.
chlorine either separately in themselves or by combining two, three.or more
chemicals together to produce chlorine therefrom.
In witness whereof, I, the said Wilhelm Adolf Von Kanig, have here-
unto set my hand and seal, this Twenty-ninth day of February, in the
year of our Lord One thousand eight hundred and sixty.
