IMPROVEMENTS IN REFINING SUGAR, AND IN APPARATUS EMPLOYED THEREIN
Year: 1865

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street, in
the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN REFINING SUGAR, AND IN APPARATUS EMPLOYED THEREIN."-A communi-
cation from abroad by Alfred Guillon, of Nantes, France..
led the 29th August 1865, and dated the 3rd March 1865.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 3rd March 1865.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN REFINING SUGAR, AND IN APPARATUS EMPLOYED THEREIN," to
be as follows:-
This Invention consists in the agglomeration, without the aid of the vacuum
pan, of the crystals of sugar by means of a sweet liquid or syrup of a density
below 40° Beaumé, and of a temperature varying with the nature of the
material used.
The Invention consists also in constructing apparatus as hereafter described..
I mix the sugar to be made into loaves in a cold state, and without the
employment of heat, in a mill or mixer with a limpid syrup of a density of 36°.
Beaumé, in the proportion of about 43 quarts of syrup to 200 lbs. of sugar.,
On leaving the mixer, the mass in a perfectly homogenous state is received in

page_text: a double-bottomed pan heated by steam, where it is beated to a point not
exceeding 131° Fahrenheit, and run into moulds. Eight hours after filling, the
loaves are set to drain without receiving any decolouring, or being in any way
worked; after draining about 48 hours the loaves are removed (loché et sucé)
and stoved. A few days stoving suffices for the perfection of the loaves..
I construct my mixing mill as follows:-The mixer is composed of an
it
elongated case closed, except to an inlet and outlet for the sugar and syrup;
is fitted with an agitator with screw blades extending from one end of the case
to the other. A hopper is placed over the inlet aperture near one end of the
case. The sugar and syrup are thoroughly mixed by the rotation of the agitator,
the blades of which also carry the mass towards the opposite end of the case
over the outlet aperture, from whence, by a pipe or shoot, the mass is directed
into the double-bottomed pan heated by steam, and before named.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said. Richard Archibald Brooman in the Great Seal Patent Office
on the 1st September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of March, 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 Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such others
as I, the said Richard Archibald Brooman, 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 REFINING SUGAR, AND IN APPARATUS EMPLOYED
THEREIN," (communicated to me from abroad by Alfred Guillon, of Nantes,
France,) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, my executors or administrators, by an instrument. in
writing under my, or, their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in what

page_text: 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 Richard Archibald Brooman, 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, reference being had to the Drawings hereunto
annexed, that is to say :-
This Invention consists in the agglomeration, in the form of loaves, of the
crystals of sugar without the aid of the vacuum pan, by means of a sweet
liquid or syrup, of the density below 40° Beaumé, and of a temperature varying
with the nature of the material used.
The Invention consists also in constructing apparatus as herein-after-
described.
I mix the sugar to be made into loaves in a cold state, and without the
employment of heat, in a mill or mixer with a limpid syrup of a density of 36°
Beaumé, in the proportion of about forty-three quarts of syrup to two hundred
pounds of sugar. On leaving the mixer, the mass in a perfectly homogeneous
state is received in a double-bottomed pan heated by steam, where it is heated
to a point not exceeding 131° Fahrenheit, and run into moulds. Eight hours
(more or less) after filling, the loaves are set to drain without receiving any
decolouring, or being in any way worked; after draining about forty-eight
hours the loaves are removed (loché et sucé) and stoved. A few days stoving
suffices for the perfection of the loaves.
I construct my mixing mill as represented in the accompanying Drawing.
The mixer is composed of an elongated case I closed, except to an inlet and
outlet for the sugar and syrup; it is fitted with an agitator B with screw blades
extending from one end of the case to the other. A hopper A is placed over
the inlet aperture near one end of the case. The sugar and syrup are thoroughly
mixed by the rotation of the agitator B, the blades of which also carry the mass
towards the opposite end of the case over the outlet aperture, from whence by
a pipe or shoot E the mass is directed into a double-bottomed pan F, heated
by steam, as before explained. G is the space contained between the two
bottoms of the pan, and H is the outlet by which the mixture is run out into
moulds. The shaft D of the agitator B is driven by pulleys C and straps
or bands.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, 1 declare that I claim as the "Improve-
ments in Refining Sugar, and in Apparatus employed therein,"-

page_text: First, the agglomeration of the crystals of sugar by means of a sweet liquid
or syrup, of a density below 40° Beaumé, substantially as herein-before
described.
i
· Second, constructing a mixing mill, substantially as herein-before described
and represented in the accompanying Drawing.
Third, constructing a double-bottomed pan, substantially as herein-before
described and represented in the accompanying Drawing.
In witness whereof, I, the said Richard Archibald Brooman, have
hereunto set my hand and seal, this Thirty-first day of August, One
thousand eight hundred and sixty-five.
