page_text: LETTERS PATENT to Joseph Hall, of the Town and County of the Town
of Nottingham, Oil Merchant, for the Invention of "THE MANUFACTURE,
OR PRODUCTION OF OIL FOR THE USE OF MACHINERY OR. FOR OTHER SIMILAR
PURPOSES."
Sealed the 8th August 1865, and dated the 11th February 1865.
PROVISIONAL SPECIFICATION left by the said Joseph Hall at the Office
of the Commissioners of Patents, with his Petition, on the 11th February
1865.
I, JOSEPH HALL, of the Town and County of the Town of Nottingham,
Oil Merchant, do hereby declare the nature of the said Invention for "THE
MANUFACTURE OR PRODUCTION OF OIL FOR THE USE OF MACHINERY OR FOR OTHER
SIMILAR PURPOSES," to be as follows:-
My Invention consists in the manufacture or production of oil from the fat
of oxen, bull, or cow. I place any required quantity of the fat of oxen, bull,
or cow, in a cauldron or vessel, which I place over a heated stove or other
heated surface until the fat it contains has become thoroughly dissolved.
The dissolved fat I then run through a series of sieves to extract the refuse,
and I then pour into the vessel which received the fat thus dissolved and

page_text: whilst the fat is reduced to a liquid state a quantity of colza oil. I then
place these two ingredients on a heated surface and mix them well together
by stirring or otherwise. I then at once employ means for the clarification
of the ingredients, and this I effect by placing dry coffee or other equivalent
substance within a muslin or other bag which I insert in the liquid and stir
or otherwise mix the liquid. I then filter the liquid through flannel, next
through thick paper, and subsequently through fine paper, when it is fit for
I thus manufacture an improved oil containing less water than con-
tained in oil heretofore used, better and finer in quality, and producing less
filth or dirt in machinery when used therein.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Hall, in the Great Seal Patent Office on the 10th
August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPII
HALL, of the Town and County of the Town of Nottingham, Oil Merchant,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of February, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eight year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Hall, Her special licence that I, the said Joseph Hall, my
executors, administrators, and assigns, or such others as I, the said Joseph
Hall, 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 "THE MANUFACTURE OR
PRODUCTION OF OIL FOR THE USE OF MACHINERY OR FOR OTHER SIMILAR PURPOSES,"
upon the condition (amongst others) that I, the said Joseph Hall, my executors
or administrators, by an instrument in writing under my, or their, or one of
their bands 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 Joseph Hall, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
My Invention consists in the manufacture or production of oil from the
fat of oxen, bull, or cow in the following manner :-I place any required
quantity of the fat of oxen, bull, or cow in a cauldron or vessel which I place
over a heated stove or other heated surface until the fat which the vessel
contains has become thoroughly dissolved. The fat thus dissolved I then
run through a series of sieves to extract the refuse from it, and I then pour
into the vessel which has received the fat thus dissolved, and whilst the fat
is still in a liquid state, a quantity of colza oil. I then place the vessel
containing these two ingredients on a heated surface and mix them well
together by stirring or otherwise. And I then clarify the liquid by placing
dry coffee or equivalent substance within a bag of muslin or other equivalent
material which I insert in the liquid, and I then stir or otherwise mix the
liquid. I then proceed to filter the liquid through flannel, next through
thick paper, and subsequently through fine paper, when this has been done
the oil is fit for use. Sometimes I use only the flannel and thick paper for
filtering the liquid. I thus manufacture an improved oil, containing less
water than is contained in oil heretofore produced, and my oil is better and
purer in quality and produces less filth or dirt in machinery when used
therein.
Having now described the nature of my said Invention, and in what manner
the same may be performed, I declare that I claim as of my said Invention,
the manufacture or production of oil substantially as described.
In witness whereof, I, the said Joseph Hall, have hereunto set my hand
and seal, this Ninth day of August, in the year of our Lord One thousand
eight hundred and sixty-five.
Witness,
