IMPROVEMENTS IN SEPARATING THE MORE LIQUID PARTS FROM THE MORE SOLID PARTS OF FATTY AND OILY MATTERS, AND IN SEPARATING FATTY AND OILY MATTERS FROM FOREIGN MATTERS
Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
FERGUSSON WILSON, of Belmont, Vauxhall, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-eighth day of
February, One thousand eight hundred and forty-nine, in the twelfth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said George Fergusson Wilson, my exors, adiñors, and assigns,
Her especial license, full power, sole privilege and authority, that I, the
said George Fergusson Wilson, my exors, adñors, and assigns, or such others
as I, the said George Fergusson Wilson, my exors, adññiors, 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 in the Islands of Guernsey, Jersey, Alderney,
Sark, and Man, and in all Her said Majesty's Colonies and Plantations
abroad, my Invention of "IMPROVEMENTS IN SEPARATING THE MORE LIQUID
PARTS FROM THE MORE SOLID PARTS OF FATTY AND OILY MATTERS, AND IN
SEPARATING FATTY AND OILY MATTERS FROM FOREIGN MATTERS;" in which said
Letters Patent is contained a proviso that I, the said George Fergusson
Wilson, should cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said in part recited Letters Patent,

page_text: as in and by the same, reference being thereunto had, will more and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Fergusson Wilson, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, that is
to say :-
My Invention consists of causing the more fluid parts of fatty and oily
matters to be separated by means of centrifugal motion, thus obtaining the
solid parts separated from the oily parts, and also obtaining fatty and oily
matters from foreign matters.
And in order that my Invention may be most fully understood, and readily
carried into effect, I will proceed to describe the means pursued by me.
It is well known that water may be and is extensively extracted from linen
and other fabrics by placing such fabrics in a machine capable of being caused
to revolve with considerable speed, the fabrics resting against gratings or per-
forated surfaces.at the outer circumference or periphery of the machinery, and
several varieties of machines are now in use amongst manufacturers and others
for removing water from fabrics by such means, and such machines are suitable
for carrying out my Invention, but I prefer those sold by Mess" Seyrig and Co.,
called " Hydro-extractors;" and, in order to carry out my Invention by
machinery acting according to such principle, I employ in addition to tho
ordinary grating or perforated surfaces at the periphery a close filtering texture,
that which I have used and find to answer is strong cotton twell, but other
fabrics may be employed for the purpose; and in order to prevent the necessity
for digging out the fatty or more solid matter after the fluid part has been
separated therefrom, and also in order to prevent the concrete or substantive
matters coating over and stopping the periphery, and thus intercepting the
further passage of the fluid parts I place the fatty or oily matter which is to
be operated on in a long bag of about eight inches diameter, and of a length
which, when laid within the machines, the two ends will meet the bag resting
against the wire or other grating at the periphery of the machine. On
motion being communicated to the machine the more fluid parts will be
quickly separated. I would however remark, that the speed of the machine
should be only raised to such a degree as not to force out the stearine
or stearic acid when the more fluid only is to be separated, and this will
be judged of by the clearness or turbid character of the fluid oil which
is flowing from the machine; and as the concrete or solid matters will have a
tendency to coat over the interior of the bag next the grating the process of

page_text: the separation of the fluid parts will be quickened by turning the bag after a
time, so that that surface which has been towards the centre of the machine
may be placed outwards towards the grating. This process will be found par-
ticularly useful when removing matter that has become solid in oily matters
which have been subjected or exposed to cold, also to separate the liquid from
the harder matter in semi-fluid, oily, and fatty matters. In these cases the
room in which the machine is placed should be two or three degrees warmer
than the oily or fatty matter operated on.
This process will also be found highly useful in separating hard impurities,
such as sand, from oily and fatty matters, the fatty matters operated on being
kept fluid by the temperature of the room when necessary.
This process is also applicable for separating the fatty and oily matters from
its crushed inatrix, as in crushed copperah (dried cocoa-nut kernel) and
others. In these cases the heat of the room should be about ten degrees of
Fahrenheit above the melting degree of the fatty matter operated on.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
clain the apparatus herein spoken of for obtaining centrifugal motion; but
what I claim is, the mode of separating the more liquid parts from the more
solid parts of fatty and oily matters, and separating fatty and oily matters from
foreign matters.
In witness whereof, I, the said George Fergusson Wilson, have hereunto
set my hand and seal, this Twenty-seventh day of August, in the year
of our Lord One thousand eight hundred and forty-nine.
GEO. F. (L.S.) WILSON.
AND BE IT REMEMBERED, that on the Twenty-seventh day of August,
in the year of our Lord 1849, the aforesaid George Fergusson Wilson came
before our said Lady the Queen in Her Chancery, and acknowledged the
Specification aforesaid, and all and every thing therein contained and specified,
in form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
