Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Patent Office, Lincoln's Inn, Gentleman, send greeting.
WHEREAS His present Majesty King William the Fourth, by His Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Twenty-ninth day of June, in the first year of His reign, did, for Himself,
His heirs and successors, give and grant unto me, the said Moses Poole, His
especial licence that I, the said Moses Poole, my exors, admors, and assigns,
or such others as I, the said Moses Poole, my exors, adñiors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, and also in all His Majesty's Colonies and Plantations
abroad, the Invention of "CERTAIN IMPROVEMENTS IN APPARATUS USED FOR CERTAIN
PROCESSES OF EXTRACTING MOLASSES OR SYRUP FROM SUGAR," communicated by me
by a certain foreigner residing abroad; in which said Letters Patent is contained
a proviso, obliging me, the said Moses Poole, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature of
the said Indention, and in what manner the same is to be performed, and to
cause the same to be inrolled in His said Majesty's High Court of Chancery
within six calendar months next and immediately, after the date of the said
recited.Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
1.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Moses Poole, do hereby declare that the nature of the said Invention, and the

page_text: manner in which the same is to be performed, are particularly described and
ascertained by the following description thereof (that is to say):-
The Invention consists in the application of an exhaustion vessel or exhaus-
tion vessels, to be exhausted in the manner herein-after described, to those
processes of exhausting molasses or syrup from sugar, whereby the air is made
to press upon and rush through the sugar with great force and rapidity towards
the vacuum, and thereby cause the molasses or syrup to be exhausted or drawn
therefrom, the vacuum or exhaustion in such vessels being produced by the
condensation of steam by a Torricellian column. I would here observe, that
the principle of applying a vacuum for the purpose of causing-the-liquid-to-be
separated from the concrete matter is well-known, and consists of an open
vessel with a partition near the bottom, and thus forming a compartment at
the lower part of the vessel, from which the air is exhausted by means of
a pump, the partition being. perforated with small holes, and covered with a
cloth of silk or other. material, upon which the matter to operated upon is
placed, and the atmosphere.continuing its weight on the surface of such matt
रा

page_text: lower part of the separating vessel, the object of the present Invention is to
construct a spherical or other shaped vessel of copper or iron or other material;
one of about six cubic feet capacity is a good size, but it may be increased or
decreased ad libitum. This vessel I call the exhaustion vessel, which is to be
connected to the lower compartment of the separating vessel already described,
by a pipe having a stop-cock placed upon it. At the top part of the exhaustion
vessel is placed a cock opening outwards, to permit of the air being driven out,
and at the lower part of the exhaustion vessel there is placed a cock for
drawing off the condensing water.

is
Now, in order to set the apparatus above described in operation, sugar, i
to be spread over the partition or false bottom of the separating vessel to the
depth of three or four inches, and steam is to be permitted to flow from a
boiler, by means of a connecting pipe, having a stop-cock upon it, into the
exhaustion vessel, which will drive out the air; when this is effected the air
cock must be stopped. The exhaustion vessel having become full of steam,
the cock on the steam pipe is to be closed, and the cock placed
on what may
be called the condensing water pipe is to be opened. This condensing water
pipe leads from a reservoir of water placed above the apparatus. The part of
the pipe which is in the inside of the exhaustion vessel has a rose head
attached to it, for the purpose of distributing the water into minute jets, So
as the more readily to condense the steam contained in the exhaustion vessel,
and thus produce a vacuum therein. The state or extent of the vacuum may
be ascertained at all times by having a mecurial gage or barometer placed
in any part of the exhaustion vessel. When the steam has been condensed
the cock on the condensing water pipe is to be closed, and the cock on the
pipe which connects the exhaustion vessel with the separating vessel is to be
opened, and the result will be, that the air will press upon and rush through
the sugar with great force and rapidity into the exhaustion vessel, and will
thereby carry down the molasses or syrup into the lower part of the separating
vessel.
.:
Now, it will be evident, from the above description, that this apparatus may
be made in any sizes to suit the various places wherein it is to be put up.
The manner in which I prefer. to construct. the apparatus is to have two or
more exhaustion vessels, so that whilst one is acting on the separating. vessel
a vacuum may be formed in the other, 'and' thus a' continued succession may
be kept in action on the separating vessel.
I will now proceed to describe the manner of constructing the apparatus
when a Torricellian column is made use of for the purpose of obtaining a
vacuum. In this case the exhaustion vessel or vessels are constructed

page_text: similarly, to those above described, but in place of a steam pipe a water.
supply pipe with a stop-cock or valve, upon it must be, used. The condensing,
water pipe in this case, will not be necessary, neither will the cock placed at
the bottom of the exhaustion vessel for drawing off the. condensing water.be
required,, but the air escape cock or valve, and, the connecting pipe.between 5
the exhaustion vessel and, the, separating vessel, must be, retained. To the
bottom of the exhaustion.vessel a pipe descending about thirty-three feet and.
communicating with a reservoir below is fixed, having a stop-cock or valve,
placed upon it. In order to set this apparatus to work; the cock-on-the-pipe-
which connects the exhaustion. vessel, with the separating vessel, and the 1
cock, or valve which is on the descending pipe, must be kept closed. The
exhaustion vessel.is to be filled with water by the water supply pipe, and the,
air in the exhaustion vessel will then be driven out at the cock or valve,
placed at the top of such vessel for that purpose.. The cock or valve on,
the water supply pipe- and the air. escape cock or valve are, to be closed, I
and that on the descending pipe is to be opened, when the water.. contained.
in the exhaustion vessel will, subside to the height at which the atmosphere.
will support a column of water in a vacuum, and the exhaustion vessel which
is above that height will be left in a state of vacuum or exhaustion, when.
the cock on the pipe which connects the exhaustion vessel with the separating.2
vessel is to be opened, by which the atmosphere will be brought to press. on
and, rush, through the surface of the sugar, as before described. In this case.
two or more,exhaustion, vessels may be made use of in succession, but it. will.
not be necessary to have more than one descending pipe, but each of the
vessels must have a stop-cock or valve on the branch. pipe, which connects 2
it to the descending pipe.
Now, I would have it understood that although I have here: described
parts of apparatus which are well known and in, use, I lay no claim to the
same separately; but what I claim as the Invention is, the application.of the
exhaustion vessel or vessels, the vacuum in which is obtained by the con- .3
densation of steam, or by a Torricellian column, when used, for the purpose.
of extracting molasses or syrup from-sugar, as above described..
In witness whereof; I, the said Moses-Poole, have hereunto set my hand
..and seal, this Twenty-fourth day of December, in the year of our Lord
One thousand eight-hundred-and-thirty.
