AN IMPROVED PROCESS OF MANUFACTURING SYRUP AND SUGAR FROM MAIZE STARCH AND OTHER CEREAL GRAIN STARCH
Year: 1865

page_text: LETTERS PATENT to George Haseltine, of the "International Patent
Office," No. 12, Southampton Buildings, Chancery Lane, in the County
of Middlesex, Civil Engineer, for the Invention of "AN IMPROVED
PROCESS OF MANUFACTURING SYRUP AND SUGAR FROM MAIZE STARCH AND
OTHER CEREAL GRAIN STARCH." -A communication from abroad by
Frederick William Goessling, of Buffalo, State of New York, United
States of America, Physician and Chemist.
Sealed the 21st July 1865, and dated the 28th January 1865.
PROVISIONAL SPECIFICATION left by the said George Haseltinent
the Office of the Commissioners of Patents, with his Petition, on the
28th January 1865.
I, GEORGE HASELTINE, of the "International Patent Office," No. 12,
Southampton Buildings, Chancery Lane, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED PROCESS OF MANUFACTURING SYRUP AND SUGAR FROM MAIZE STARCH
AND OTHER CEREAL GRAIN STARCH," a communication, to be as follows:-
My improvement relates more particularly to making syrup and sugar from
maize starch, but is applicable to any kind of cereal grain starch, and
the starch for such purpose may be manufactured by any of the known
processes.
In the first place I provide three or more suitable tanks or tubs, in the
bottom of which I place a coil of lead pipe, which is connected with suitable

page_text: iron pipe on the outside of the tank; this pipe communicates with a steam
boiler in such a manner that steam may be passed through the lead pipe in
the tank at pleasure; then I put into one of these tanks about two hundred
pounds of pure water and about two pounds of oil of vitriol, and then pass
steam through the lead pipe in the tank until the acid water in the tank is
caused to boil; in the meantime I solve one hundred pounds of starch in
one of the other tanks, which stands contiguous to the first named, with about
one hundred pounds of pure water and half a pound of oil of vitriol, and then
draw off slowly this solved starch into the boiled acid water in the tank first
named, and then cover the tank closely, and boil the now starchy solution
therein for about two hours; then I put into this same starchy solution about
one pound of pulverized wood charcoal, and boil again for about one hour;
next, I
pass this liquid solution into another tank, and neutralize it with car-
bonate of lime; after that the liquid is filtered through suitable bag filters
and transferred into the other tank traversed interiorly with the lead pipe, as
before described, where it is treated with half pound of carbonate of quick-
lime, preferably Duppltsauer's preparation, and two pounds of bullock's
blood. Steam is now introduced until the liquid is heated to boiling point,
whereupon all the impurities and foreign matter will rise to the surface,
whence they must be removed. The liquid now remaining in the tank is a
sugar liquid, which must be filtered through animal charcoal, and then boiled
down in vacuo to forty degrees specific gravity, which produces a true cane
syrup fit for use,
In order to convert the syrup thus produced into cane-like sugar, it is boiled
down in vacuo to forty-five degrees specific gravity, and then transferred to a
crystallizing room kept at a temperature of about ninety or one hundred
degrees Fahrenheit, After being crystallized and removed from the moulds, it
is placed on plaster of Paris plates in a room, at a temperature of about one
hundred degrees Fahrenheit, to dry.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed 3
by the said George Haseltine in the Great Seal Patent Office on the
27th July 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 12, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer, send 3.
greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of January, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Haseltine, Her special licence that I, the said George
Haseltine, my executors, administrators, and assigns, or such others as I,
the said George Haseltine, 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 "AN IMPROVED PROCESS OF MANUFACTURING SYRUP AND SUGAR FROM MAIZE
STARCH AND OTHER CEREAL GRAIN STARCH," a communication, upon the con-
dition (amongst others) that I, the said George Haseltine, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, 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 George Haseltine, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My improvement relates more particularly to making syrup and sugar from
maize starch, but is applicable and may be applied to any kind of cereal grain
starch, and the starch for such purpose may be manufactured by any of the
well-known processes.
I, in the first place, provide three or more suitable tanks or vats, in the
bottom of which I place a coil of lead pipe, which is connected with suitable
iron pipes on the outside of the tanks; this pipe communicates with a steam
boiler in such manner that steam may be passed through the lead pipe in the
tanks at pleasure; then I put into one of these tanks about two hundred
pounds of pure water and about two pounds of oil of vitriol, and then pass
steam through the lead pipe in said tank until the acid water in this tank is
caused to boil; in the meantime I solve one hundred pounds of starch in one
of the other tanks, which stands contiguous to the first-named, with about one
hundred pounds of pure water and half a pound of oil of vitriol, and then draw
off slowly this solved starch into the boiled acid water in the tank first-named,

page_text: and then cover the tank closely, and boil the now starchy solution therein for
about two hours; then I put into this same starchy solution about one pound
of pulverized wood charcoal, and boil again for about one hour; next, I pass
this liquid solution into another tank, and neutralize it with carbonate of
lime; after that the liquid is filtered through suitable bag filters, and trans-
ferred into the other tank traversed internally with the lead pipe, as before
described, where it is treated with half a pound of carbonate of quicklime and
two pounds of bullock's blood. Steam is now introduced until the liquid is
heated to boiling point, whereupon all the impurities and foreign matter in
the liquid will then rise to the surface when they must be removed. The
liquid now remaining in the tank is a sugar liquid, which must be filtered
through animal charcoal, and then boiled down in vacuo to forty degrees
specific gravity, which produces a true cane syrup fit for use.
In order to convert the syrup thus produced into cane-like sugar, it is
boiled down in vacuo to forty-five degrees specific gravity, and then transferred
to suitable moulds in a crystalizing room at a temperature of about 90° or
100° Fahrenheit. After being crystalized and taken from the moulds it is
placed on plaster of Paris plates in a room, at a temperature of about 100°
Fahrenheit, to dry; then the process is complete, and a fine and good quality
of cane-like sugar is produced.
Having thus fully described the said Invention, as communicated to me from
my foreign correspondent, and shown how the same may be conveniently and
advantageously carried into practice, I claim, the manufacture of syrup and
sugar from corn starch and other cereal grain starch by the process sub-
stantially as herein described.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and seal, this Seventeenth day of July, in the year of our Lord
One thousand eight hundred and sixty-five.
Witness,
WILLIAM ROBERT LAKE.
GEORGE HASELTINE. (L.S.)
