Year: 1855

page_text: LETTERS PATENT to William Teall, of Wakefield, in the County of York,
Engineer, for the Invention of "A MODE OF TREATING CERTAIN MATERIALS
CONTAINING FATTY OR OILY SUBSTANCES, IN ORDER TO EXTRACT THOSE FATTY OR
OILY SUBSTANCES THEREFROM."
Sealed the 28th December 1855, and dated the 22nd October. 1855.
PROVISIONAL SPECIFICATION left by the said William Teall at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
October 1855.
I, WILLIAM TEALL, of Wakefield, in the County of York, Engineer, do
hereby declare the nature of the said Invention for "A MODE OF TREATING
CERTAIN MATERIALS CONTAINING FATTY OR OILY SUBSTANCES, IN ORDER TO EXTRACT
THOSE FATTY OR OILY SUBSTANCES THEREFROM," to be as follows:-
To extract the oil or grease from the waste or shoddy produced in the
manufacture of all kinds of woollen or other goods, in the making of which oil
or grease is used, as, for instance, the cleansings or waste of the machines
called " willies," and other machinery used in the manufacture of woollen
goods, as also the wipings used for cleaning engines and other machinery.
The materials alluded to, and containing the fatty or oily substances, are
put into proper tanks or vats, with a sufficient quantity of water slightly acidu-
lated with sulphuric or other suitable acid, and the whole is made to boil, and
stirred up until it becomes a sort of pulp. This pulp is then put into bags or

page_text: cloths of close texture, which are put into closed presses, into which steam is
introduced, and are then pressed in the same way as is practised for extracting
the grease from the magma produced from soapy waters, and which mode has
been before described in several. Patents, and is well known.
SPECIFICATION in pursuance of the conditions. of the. Letters Patent, filed
by the said William Teall in the Great Seal Patent Office on the
22nd April 1856.
TO ALL TO WHOM THESE PRESENTS. SHALL COME, I, WILLIAM
TEALL, of Wakefield, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of October, in the year of our
Lord. One thousand, eight hundred and fifty-five, in the nineteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Teall, Her special licence that I, the said William
Teall, my executors, administrators, and assigns, or such others as I, the
said William Teall, my executors, administrators, and assigns, should at any
time agree with; and no others, from time to time and at all times there-
after 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 "A MODE
OF TREATING CERTAIN MATERIALS, CONTAINING FATTY OR OILY SUBSTANCES, IN ORDER
TO EXTRACT THOSE FATTY OR OILY SUBSTANCES THEREFROM," upon the condition
(amongst others) that I, the said William Teall, 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 Inven-
tion, 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 William Teall, do hereby declaré
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
My Invention has for its object the extraction of oil or grease from the waste
or shoddy produced in the manufacture of woollen or other goods, or from
refuse material which has become saturated or impregnated with oil or grease,
as the cleansing and waste of machines called willows, and other machines

page_text: used in the manufacture of woollen goods, or the wipings used for cleansing
engines and other machinery. The material containing the oily or fatty matters
to be extracted is put into proper tanks or vats, with a sufficient quantity of
water slightly acidulated with sulphuric or other acid, and the whole is made
to boil, and stirred up until it becomes a sort of pulp. The pulp so provided
is put into bags or cloths of close texture, which are put into closed presses,
into which steam is introduced, and pressed in the same way as in the ex-
traction of grease from the magma produced from soapy water, as is well
understood. The boiling of the mixture, though not necessary, facilitates
the operation, especially when the material is much clotted together, pre-
paring the material for the presses, and facilitating the penetration of the
steam to the centre of the bags, thus softening or liquifying the
the grease
contained in the shoddy and preparing it for pressure.
Having thus described the nature of my said Invention and in what manner
the same is to be performed, I hereby declare that what I claim as my Inven-
tion is, the treating shoddy or waste materials containing oily or greasy sub-
stances with heat and pressure for the extraction of the oil or grease therefrom,
in the manner above described.
In witness whereof, I have hereunto set my hand and affixed my seal,
this Twenty-first day of April, in the year of our Lord One thousand
eight hundred and fifty-six.
WILLIAM TEALL. (L.S.)
Signed, sealed, and delivered by the above-named
William Teall, in the presence of
JOSEPH WILKINSON HAWORTH,
Maltster,
Wakefield.
