Year: 1872

page_text: LETTERS PATENT to Paul Toepler, of Gracechurch Street, in the City
of London, for the Invention of "AN IMPROVED METHOD OF TREATING
AND CLEANING ALL KINDS OF ANIMAL AND VEGETABLE FIBROUS MATERIALS
CONTAINING GREASE."
Scaled the 28th June 1872, and dated the 1st January 1872.
PROVISIONAL SPECIFICATION left by the said Paul Toepler at the
Office of the Commissioners of Patents, with his Petition, on the
1st January 1872.
I, Paul ToeplLER, of Gracechurch Street, in the City of London, do
hereby declare the nature of the said Invention for "AN IMPROVED
METHOD OF TREATING AND CLEANING ALL KINDS OF ANIMAL AND VEGETABLE
FIBROUS MATERIALS CONTAINING GREASE," to be as follows:-
This Invention consists in operating with fusil oil upon raw or
manufactured or partly manufactured animal and vegetable fibrous
materials containing grease, for the purpose of cleaning the said fibrous
materials and separating the grease therefrom, as follows:-
The fibrous material to be operated upon is placed in a bath of fusil
oil and left therein or passed through it until the desired quantity of

page_text: grease is extracted from the fibre: The chemical compound formed by
the fusil oil combining with the grease extracted from the fibre is then
removed from the bath (which may be effected by a cock placed in the
bottom of the bath), and the fibrous materials that remain in the bath
will be found sufficiently freed from grease by the action of the fusil oil 5
therein, as above stated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Paul Toepler in the Great Seal Patent Office on the
1st July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL

within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED METHOD OF
TREATING AND CLEANING ALL KINDS OF ANIMAL AND VEGETABLE FIBROUS
MATERIALS CONTAINING GREASE," upon the condition (amongst others) that I,

page_text: 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 with fusil oil upon raw, or manu-
factured, or partly manufactured animal and vegetable fibrous materials
containing grease, for the purpose of cleaning the said fibrous materials
and separating the grease therefrom, as follows:-
The fibrous material to be operated upon is placed in a bath of fusil
oil and left therein or passed through it until the desired quantity of
grease is extracted from the fibre. The chemical compound formed by
the fusil oil combining with the grease extracted from the fibre is then
removed from the bath (which may be effected by a cock placed in the
bottom of the bath), and the fibrous materials that remain in the bathi
will be found sufficiently freed from grease by the action of the fusil oil
thercon, as above stated.
If desirable, the fibrous materials may be afterwards washed in
water.
Having now described the nature and object of my said Invention for
"An Improved Method of Treating and Cleaning all Kinds of Animal
and Vegetable Fibrous Materials Containing Grease," together with the
means by which it may be effected, I would remark that what I claim
as my Invention is, operating upon animal and vegetable fibres with fusil
oil for cleaning the said fibres and separating the grease therefrom, sub-
stantially as above described.
In witness whereof, I, the said Paul Toepler, have hereunto set
my hand and seal, this Twenty-ninth day of June, in the year of
our Lord One thousand eight hundred and seventy-two.
