Year: 1870

page_text: LETTERS PATENT to Paul Toepler, of Gracechureh Street, in the
66
City of London, for the Invention of AN IMPROVED PROCESS FOR
AVING WOOL AND SEDARATING THE GREASE THEREFROM.
Sealed the 15th April 1871, and dated the 18th October 1870.
PROVISIONAL SPECIFICATION left by the said Paul Toepler at the
Office of the Commissioners of Patents, with his Petition, on the
18th October 1870.
I, PAUL TOEPLER, of Gracechurch Street, in the City of London,
do hereby declare the nature of the said Invention for *** AN IMPROVED
PROCESS FOR CLEANING WOOL AND SEPARATING THE GREASE THEREPROM," to be
as follows: -
This Invention is designed for cleaning all kinds of wool, especially
raw wool, and freeing it from grease by a cold process instead of by heat
as heretofore for cleaning and freeing the wool from the grease it
contains. The wool to be cleaned is placed in a cold bath of amyl
alcohol, and left therein until all grease is removed from the wool. After

page_text: removing the chemical compound formed by the amyl alcohol com-
bining with the grease in the wool, which may be effected by means of
a cock fixed in the bottom of the bath, the wool remains clean and free
from grease. By the above improved process less waste of the wool is
occasioned. If desirable the wool may be afterwards washed in cold
water.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Paul Toepler in the Great Seal Patent Office on
the 18th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL
TOEPLER, of Gracechurch Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of October, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Paul Toepler, Her special licence that
I, the said Paul Toepler, my executors, administrators, and assigns, or
such others as I, the said Paul Toepler, 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 "AN IMPROVED PROCESS FOR CLEANING
WOOL AND SEPARATING THE GREASE THEREFROM," upon the condition (amongst
others) that I, the said Paul Toepler, 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 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 Paul Toepler, do hereby declare

page_text: performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
This Invention is designed for cleaning all kinds of wool, especially
raw wool, and freeing it from grease by a cold process, and without the
application of heat as heretofore practised for cleaning wool and sepa-
ting the grease therefrom. The wool to be cleaned is placed in a bath
or vessel containing amyl alcohol, and left therein until the desired
quantity of grease is removed from the wool, the chemical compound
formed by the amyl alcohol combining with the grease from the wool is
then removed, and the amyl alcohol may be again used with or without
an addition of fresh amyl alcohol added from time to time as may be
required. If desirable the wool may be afterwards washed in cold
water. By the above described improved process less waste of the
wool is occasioned as the wool is not injured by the alcohol.
Having now fully described the nature and object of my said Inven-
tion for "An Improved Process for Cleaning Wool and Separating the
Grease therefrom," together with the best means I am acquainted with
for carrying the same into practical effect, I would remark in conclusion
that I hereby declare my Invention to consist in, and I claim, operating
upon wool with cold amyl alcohol for cleaning it and separating the
grease therefrom as above stated.
In witness whereof, I, the said Paul Toepler, have hereunto set
my hand and seal, this Eighteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-one.
