AN IMPROVED PROCESS FOR CLEANING COTTON YARN, COTTON WASTE, AND SUCH LIKE FIBROUS MATERIALS, AND IN SEPARATING THE GREASE THEREFROM, AND IN THE MODE OF TREATING THE PRODUCTS RESULTING FROM SUCH SAID PROCESS TO FIT THEM FOR MANUFACTURING PURPOSES
Year: 1871

page_text: LETTERS PATENT to Paul Toepler, of Gracechurch Strect, in the
City of London, for the Invention of "AN IMPROVED PROCESS FOR
CLEANING COTTON YARN, COTTON WASTE, AND SUCH LIKE FIBROUS MATERIALS,
AND IN SEPARATING THE GREASE THEREFROM, AND IN THE MODE OF TREATING
THE PRODUCTS RESULTING FROM SUCH SAID PROCESS TO FIT THEM FOR
MANUFACTURING PURPOSES."
ealed the 13th October 1871, and dated the 21st April 1871.
PROVISIONAL SPECIFICATION left by the said Paul Toepler at the
Office of the Commissioners of Patents, with his Petition, on the
21st April 1871.
I, PAUL TOEPLER, of Gracechurch Street, in the City of London, do
5 hereby declare the nature of the said Invention for "AN IMPROVED PROCESS
FOR CLEANING COTTON YARN, COTTON WASTE, AND SUCH LIKE FIBROUS MATERIALS,
AND IN SEPARATING THE GREASE THEREFROM, AND IN THE MODE OF TREATING THE
21st April 1871.
I, PAUL TOEPLER, of Gracechurch Street, in the City of London, do
5 hereby declare the nature of the said Invention for "AN IMPROVED PROCESS
FOR CLEANING COTTON YARN, COTTON WASTE, AND SUCH LIKE FIBROUS MATERIALS,
AND IN SEPARATING THE GREASE THEREFROM, AND IN THE MODE OF TREATING THE

page_text: PRODUCTS RESULTING FROM SUCH SAID PROCESS TO FIT THEM FOR MANUFACTURING
PURPOSES," to be as follows:-
This Invention consists in operating upon cotton yarn, cotton waste,
and such like fibrous materials with cold amyl alcohol as follows:-The
fibre intended to be operated upon is placed in a bath containing cold
amyl alcohol and is left therein until the desired quantity of grease is
separated or extracted from the fibre by the chemical action of the
amyl alcohol thereon. The chemical compound or product thus formed
by the amyl alcohol combining with the grease contained in or mixed
with the fibrous materials I propose to place in a still of the ordinary
kind, and operate thercon with heat, by which I distil or bring over the
amyl alcohol and separate it from the grease, and by these means an
enabled to again use the amyl alcohol, and thus effect economy in the
cost of the process.
The grease that remains in the bottom of the still contains a large
percentage of stearine well adapted for the manufacture of candles,
and the residue from the grease may be employed for lubricating and
other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Paul Toepler in the Great Seal Patent Office on
the 20th October 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Paul
TOEPLER, of Gracechurch Strect, in the City of London, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

page_text: and Isle of Man, an Invention for "AN IMPROVED PROCESS FOR CLEANING
COTTON YARN, COTTON WASTE, AND SUCH LIKE FIBROUS MATERIALS, AND IN
SEPARATING THE GREASE THEREFROM, AND IN THE MODE OF TREATING THE PRODUCTS
RESULTING FROM SUCH SAID PROCESS TO FIT THEM FOR MANUFACTURING PURPOSES,"
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 scals, 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 imme-
diately after the date of the said Letters Patent.
.
NOW KNOW YE, that I, the said Paul Toepler, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, that is to say :-
This Invention consists in operating upon cotton yarn, cotton waste,
and such like fibrous materials with cold amyl alcohol as follows:-The
fibre intended to be operated upon is placed in a bath containing cold
amyl alcohol, and is left therein until the desired quantity of grease is
separated or extracted from the fibre by the chemical action of the
amyl alcohol thereon. The chemical compound or product thus formed
by the amyl alcohol combining with the grease contained in or mixed
with the fibrous materials I propose to place in a still of the ordinary
kind and operate thereon with heat, by which I distil or bring over the
amyl alcohol and separate it from the grease, and by these means am
enabled to again use the amyl alcohol, and thus effect economy in the
cost of the process.
The grease that remains in the bottom of the still contains a large
percentage of stearine well adapted for the manufacture of candles, and
the residue from the grease may be employed for lubricating and other
purposes.
Having now fully described and set forth the nature and object of
my said Invention for an "Improved Process for Cleaning Cotton Yarn,
Cotton Waste, and such like Fibrous Materials, and in Separating the
Grease therefrom, and in the Mode of Treating the Products Resulting
from such said Process, to fit them for Manufacturing Purposes,"
together with the means by which it may be effected, I claim operating

page_text: upon cotton yarn, cotton waste, and such like fibrous materials with
cold amyl alcohol, in the manner and for the purposes above stated.
In witness whereof, I, the said Paul Toepler, have hercunto set
my hand and seal, this Eighteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-one.
