I EDWARD TAYLOR of Yorkshire Street Rochdale in the County of Lancaster
Chemist and Druggist do hereby declare the nature of my invention for AN
IMPROVED METHOD OF PURIFYING AND DECOLOURING THE WATER IN WHICH SILK
AND OTHER FIBROUS MATERIALS HAVE BEEN BOILED ALONG WITH SOAP, AND THE
REFUSE LIQUID OR DYE IN WHICH SILK AND OTHER FIBROUS MATERIALS HAVE
BEEN CLEANSED OR DYED AND RECOVERING USEFUL PRODUCTS FROM SUCH WATER
AND REFUSE LIQUID OR DYE to be as follows:-
My invention consists in a method of purifying and decolouring the water in
which silk or other fibrous material has been boiled along with soap and the refuse
liquid or dye in which silk or other fibrous material has been cleansed or dyed and
of recovering from such water the fat of the soap and the matters washed out of
the silk or other fibrous material during the boiling along with soap and cleansing
or dyeing of such silk or other fibrous material.
The water in which the silk or other fibrous material has been boiled along with
soap and the refuse liquid or dye in which the silk or other fibrous material has
been cleansed or dyed I shall hereinafter call the waste liquor.
In carrying my invention into effect I use chlorine which I apply as I will now
describe I pump or run the waste liquor into a tank or vessel and then by means
of a pipe or pipes and other suitable apparatus blow chlorine into the waste liquor
above mentioned-After allowing the various matters hereinafter called the
separated matters which will be separated or precipitated from the waste liquor by
the chlorine, to subside, I filter or run off the clear liquid and then remove the said
separated matters from the tank or vessel above mentioned in any suitable manner-
The said separated matters may be treated for the recovery of the therein contained
fatty matter or may be treated in any suitable manner for the utilization of the
various matters therein contained.

I EDWARD TAYLOR of Yorkshire Street, Rochdale in the County of Lancaster
Chemist and Druggist do hereby declare the nature of my invention for AN
IMPROVED METHOD OF PURIFYING AND DECOLOURING THE WATER IN WHICH SILK
AND OTHER, FIBROUS MATERIALS HAVE BEEN BOILED ALONG WITH SOAP AND THE
REFUSE LIQUID OR DYE IN WHICH SILK AND OTHER FIBROUS MATERIALS HAVE
BEEN CLEANSED OR DYED AND RECOVERING USEFUL PRODUCTS FROM SUCH WATER
AND REFUSE LIQUID OR DYE, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:―
My invention consists in a method of purifying and decolouring the water in
which silk or other fibrous material has been boiled along with soap and the refuse
liquid or dye in which silk or other fibrous material has been cleansed or dyed and
of recovering from such water and refuse liquid or dye the fat of the soap and
other matters washed out of the silk or other fibrous material during the boiling
with soap and cleansing or dyeing of such silk or other fibrous material.
The water in which the silk or other fibrous material has been boiled along with
soap and the refuse liquid or dye in which the silk or other fibrous material has
been cleansed or dyed I shall hereinafter call the waste liquor.
In carrying my invention into effect I use chlorine which I apply as I will now
describe. I pump or run the waste liquor into a tank or vessel and then by means
of a pipe or pipes and other suitable apparatus blow chlorine into the waste liquor
above mentioned-After allowing the various matters hereinafter called the
separated matters which will be separated or precipitated from the waste liquor by
the chlorine to subside, I filter or run off the clear liquid and then remove the said
separated matters from the tank or vessel above mentioned in any suitable manner
The said separated matters may be treated for the recovery of the therein contained
fatty matters or may be treated in any suitable manner for the utilization of the
various matters contained therein.
In order that my invention may be better understood I will now describe an
arrangement of apparatus by means of which my invention may be carried into
effect, which apparatus is shown by Figs. 1 and 2 of the accompanying drawing
Fig. 1 being an elevation partly in section and Fig. 2 a plan, similar letters of
reference being applied to corresponding parts in both of the figures. A is a tank
supported by the beams B or any other suitable supports-C is a pipe provided
with a valve D which valve is kept closed by means of a weight E placed upon
the lever F―The pipe C passes through the bottom of the tank A and is connected
to pipes G. H. J. K-The pipe C is in communication at its end C¹ with any suitable

page_text: apparatus by means of which a supply of chlorine at a suitable pressure may be
obtained by any suitable process.
A quantity of waste liquor is supplied through a pipe L to the tank A and the
weight E being removed from the lever F connected to the valve D chlorine is
allowed to flow through the pipes G. H J. K and into the waste liquor contained in
the tank A until the said chlorine produces a curdling effect upon the waste liquor
in the tank A-When the chlorine has produced a curdling effect upon the waste
liquor in the tank A the weight E is again placed upon the lever F and the flow of
chlorine into the tank A is shut off.
The contents of the tank A are then allowed to stand for about eight hours to
allow the curdled or separated matters to separate from the liquid matters-The
clear liquid matters are then allowed to run off from the tank by means of a tap M
and leave the curdled or separated matters in the lower part of the tank A.--A
plug N is then removed from the bottom of the tank A and the curdled or separated
matters are then run off through a hole previously closed by the plug Ñ-The
curdled or separated matters may be conducted by a trough O or other convenient
means to any convenient place to be treated for the recovery of the therein con-
tained fatty matters or to be treated in any suitable manner for the utilization of
the various matters contained therein-but I prefer to conduct the said curdled or
separated matters to a filter of any suitable construction by means of which the
superfluous liquid may be removed and afterwards treat the said curdled or separated
matters in any suitable manner for the utilization of the various matters contained
therein.
In cases in which it is only desired to obtain from the said curdled or separated
matters the fatty matters contained therein-I subject the said curdled or separated
matters to heat and pressure, as is ordinarily done to separate fatty matters from
other matters containing them.
After the curdled or separated matters have been removed from the tank A the
hole in the bottom of the tank A is again closed by means of the plug N the tap M
is closed and a further quantity of waste liquor is run into the tank A by means
of the pipe L and treated with chlorine as above described-Although I have above
described certain apparatus as being employed in carrying my invention into effect
I would have it understood that other arrangements of apparatus may be employed
to bring the chlorine into contact with the waste liquor.
Having thus described and ascertained the nature of my said invention and
in what manner the same is to be performed I declare that what I claim is :—
The improved process herein before described for purifying or decolouring the
water or refuse liquid or dye in which silk or other fibrous materials have been
boiled along with soap or cleansed or dyed, and recovering from such water or
refuse liquid or dye the fatty and other matters contained therein which process
consists in subjecting such water or refuse liquid to the action of chlorine.
