Year: 1859

page_text: LETTERS PATENT to Augustus William Gadesden, of 56, Leman Street,
Goodman's Fields, for the Invention of "IMPROVEMENTS IN PRODUCING
SOLUTIONS OF SUGAR."
Sealed the 13th October 1859, and dated the 25th April 1859.
PROVISIONAL SPECIFICATION left by the said Augustus William Gadesden
at the Office of the Commissioners of Patents, with his Petition, on
the 25th April 1859.
I, AUGUSTUS WILLIAM GADESDEN, of 56, Leman Street, Goodman's Fields,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN PRO-
DUCING SOLUTIONS OF SUGAR," to be as follows:-
This Invention has for its object improvements in producing solutions of
sugar. For these purposes, I employ a vessel having by preference a hemi-
spherical bottom, to which heat may be applied either by an internal coil of
steam pipes, by a steam jacket, or by other convenient means; across the lower
part of this vessel is a perforated false bottom or partition on which the sugar
to be dissolved is placed. In connection with this vessel is a cylinder, of
which the lower end descends below, and the upper end rises above the per-
forated partitión or false bottom. In the cylinder, a screw or suitable propeller.
is applied, by which the water or liquor is constantly raised from the under to
the upper side of the partition or false bottom, and is thrown on to the sugar
to be dissolved.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUSTUS
WILLIAM GADESDEN, of 56, Leman Street, Goodman's Fields, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of April, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Augustus William Gadesden, Her special licence that I, the said
Augustus William Gadesden, my executors, administrators, and assigns, or
such others as I, the said Augustus William Gadesden, 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 PRODUCING SOLUTIONS OF
SUGAR,"
upon the condition (amongst others) that I, the said Augustus
William Gadesden, 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 Augustus William Gadesden, 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 has for its object improvements in producing solutions of
sugar. For this purpose, I employ a vessel having by preference a hemi-
spherical bottom, to which heat may be applied either by an internal coil of
steam pipes, by a steam jacket, or by other convenient means; across the lower
part of this vessel is a perforated false bottom or partition, on which the sugar
to be dissolved is placed. In connection with this vessel is a cylinder, of
which the lower end descends below, and the upper end rises above the per-
forated partition or false bottom. In the cylinder a screw or suitable propeller
is applied, by which the water or liquor is constantly raised from the under to

page_text: the upper side of the partition or false bottom, and is thrown on to the sugar
to be dissolved.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same. I prefer
I prefer to use a screw in
the cylinder above mentioned, though other mechanical means may be used
for continually raising the liquor above the perforated false bottom. The
upper part of the cylinder which comes above the false perforated bottom is
made to slide up and down in order that it may be raised or lowered
according as there is a greater or less quantity of sugar to be dissolved,
so as to keep the upper part of the cylinder 2 or 3 inches above the level of
the water or liquor. The quantity of water required having been put into the
vessel, and the quantity of sugar to be dissolved having been put on the per-
forated bottom, the screw is to be set in motion, by which the water will be
continually raised and flow over the top of the cylinder on all sides down on
to the sugar, by which the water will progressively dissolve and carry down
more and more of the sugar, till the whole is dissolved; the liquor during the
process being kept to such temperature as may be desired (I prefer a tem-
perature of 180° to 200° Fahrenheit,) by admitting steam to flow more or less
freely to a jacket or to a coil of pipes in the lower part of the vessel.
I make no claim to any of the parts of the apparatus separately, but what
I claim is, the combined apparatus herein described.
In witness whereof, I, the said Augustus William Gadesden, have
hereunto set my hand and seal, this Twenty-second day of October,
in the year of our Lord One thousand eight hundred and fifty-nine.
AUGUSTUS W". GADESDEN. (L.S.)
