IMPROVEMENTS IN SEPARATING AND RECOVERING WOOL FROM FABRICS COMPOSED OF WOOL, OR " AND WORD VEOFTABLE SUBSTANCES
Year: 1859

page_text: LETTERS PATENT to Robert Bell, of Paris, in the Empire of France,
and of the Office for Patents, No. 4, Trafalgar Square, Charing Cross,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
SEPARATING AND RECOVERING WOOL FROM FABRICS COMPOSED OF WOOL, OR
"
AND WORD VEOFTABLE SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Robert Bell at the Office
of the Commissioners of Patents, with his Petition, on the 12th February
1859.
I, ROBERT BELL, of Paris, in the Empire of France, and of the Office for
Patents, No. 4, Trafalgar Square, Charing Cross, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SEPARATING AND RECOVERING WOOL FROM FABRICS COMPOSED OF WOOL, OR WOOL
IN CONNECTION WITH COTTON AND OTHER VEGETABLE SUBSTANCES,'
follows:-
This Invention consists in a method of obtaining the wool from mixed

page_text: fabrics of wool with vegetable fibres. For this. purpose I take muriate of
manganese, such as is ordinarily obtained as a residuum in the manufacture
of bleaching powder, in which state it is mixed more or less with chloride
of iron.
The rags composed of wool and vegetable fibre, such as cotton or flax, are
steeped in a solution of the above muriate of manganese, which rots or decom-
poses the vegetable, and leaves uninjured the animal fibre therein. The two
are then separated by processes well known.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Bell in the Great Seal Patent Office on the 12th
August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
BELL, of Paris, and of the Office for Patents, No. 4, Trafalgar Square, Charing
Cross, in the County of Middlesex, send greeting.
WHEREAS. Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of February, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Robert Bell, Her special licence that I, the said Robert Bell, my
executors, administrators, and assigns, or such others as I, the said Robert
Bell, 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 "IMPROVEMENTS IN
SEPARATING AND RECOVERING WOOL FROM FABRICS COMPOSED OF WOOL, OR WOOL IN
CONNECTION WITH COTTON AND OTHER VEGETABLE SUBSTANCES," upon the condition
(amongst others) that I, the said Robert Bell, 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 Iuven-
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 Robert Bell, 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:-
This Invention consists in a method of obtaining the wool from mixed
fabrics of wool with vegetable fibres; for this purpose I take muriate of man-
ganese such as is ordinarily obtained as a residuum in the manufacture of
bleaching powder, in which state it is mixed more or less with chloride
of iron.
The rags composed of wool and vegetable fibre, such as cotton or flax, are
steeped in a solution of the above muriate of manganese, which rots or decom-
poses the vegetable, and leaves uninjured the animal fibre therein. The two
are then separated by processes well known.
In order to explain my said Invention as completely as possible, I now
procced to describe the best means I am acquainted with for carrying the same
into practical effect, as follows:-
My Invention consists in the employment of clorure of manganese,
feruginous or cloryde of manganese feruginous, being the residue from the
fabrication of clorures or hypoclorites discoloring and disinfecting for disen-
gaging and separating the vegetable textile matters contained in tissues in
general.
According to the nature of the products I treat, I employ the clorure of
manganese feruginous in various proportions with water, thus for strong
tissues equal proportions of water and clorure of manganese; for fine tissues,
two of water to one of the clorure. I let the tissues soak for a time more or
less long, according to the nature of the products upon which I operate.
Upon taking them from this bath, they are squeezed by means of a press or
any suitable means. The tissues are then placed in a centrifugal machine.
The dessication being complete, they are placed upon hurdles arranged in a
stove or drying room, heated by vapour or in any other manner. I leave
them exposed there during a time more or less long. The tissues are imme-
diately carded, and the produce obtained is washed in an alkaline bath, and
afterwards in a great quantity of water.

Having now fully described the nature and object of my said Invention of
Improvements in Separating and Recovering Wool from Fabrics composed
of Wool, or Wool in connection with Cotton and other Vegetable Substances,"
and the manner in which the same to be performed, I would remark, in
conclusion, that I do not confine myself to the particular mechanical means
before described, as various means may be employed for effecting the desired
object; but what I claim as my Invention is the employment of clorure or

page_text: clorydrate of manganese ferruginous for the purpose herein described and
set forth.
In witness whereof, I, the said Robert Bell, have hereunto set my
hand and seal, this Sixth day of August, in the year of our Lord
One thousand eight hundred and fifty-nine.

ALEX. PRINCE, Agent for Patents,
