We, EDGAR SIDDONS WILSON, Chemist, and ALFRED BANNEN O'CONNOR,
Physician, both of Camberwell in the county of Surrey do hereby declare the
nature of our said invention for AN IMPROVED METHOD OF OPERATING UPON
$6
OILY AND GREASY RAGS AND FIBROUS MATERIAL AND IN RECOVERING OIL AND
GREASE THEREFROM to be as follows:-
"
This process has for its object the purification and recovery of oiled and greasy
fibres and extracting. valuable products therefrom (cotton and other wastes) by
means of chlorinated alkaline leys, hypochlorites of soda or potash.
The process at present preferred is as follows to be varied if necessary according
to the nature of the waste under treatment.
The
The loose oil is first extracted by hydro extractors or other suitable means.
waste is then boiled in water or very weak leys any oil that rises to the surface
being skimmed off.
The liquor is then drawn off into tanks in order that the greases or oils may
come to the surface (If leys have been used the addition of sulphuric or other
mineral acid may be necessary to facilitate the separation).
A solution of chlorinated leys is then added to the waste at a strength of say
from 5 to 10 degrees Twaddell, the whole strongly agitated for some time at a
temperature of 140 to 180 degrees Fah. The advantage of retaining this.
temperature is that emulsification can be attained more readily than at the boiling
point as by boiling the bypochlorites are converted into chlorides and chlorates
which greatly retards the process.

Physician both of Camberwell in the county of Surrey, do hereby declare the
nature of our said invention for "AN IMPROVED METHOD OF OPERATING UPON
OILY AND GREASY RAGS AND FIBROUS MATERIAL AND IN RECOVERING OIL AND
GREASE THEREFROM," and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This process has for its object the purification and recovery of oiled and greasy
fibres and extracting valuable. products therefrom (cotton and other wastes) by
means of chlorinated alkaline leys, hypochlorites of soda or potash.
The process at present preferred is as follows to be varied if necessary according
to the nature of the waste under treatment.
:
The loose oil is first extracted by hydro-extractors or other suitable means. The
waste is then boiled in water or very weak leys any oil that rises to the surface
being skimmed off.
The liquor is then drawn off into tanks in order that the greases or oils may
come to the surface. (If leys have been used the addition of sulphuric or other
mineral acid may be necessary to facilitate the separation.) The waste is then
boiled in water containing a small percentage of soap, a solution of chlorinated leys
is then added at a strength of say from 15 to 20 degrees Twaddell the whole
strongly agitated for some time at a temperature of 140 to 180 degrees Fah. The
advantage of retaining this temperature is that emulsification can be attained
more readily than at the boiling point as by boiling the hypochlorites are converted
into chlorides and chlorates which greatly retards the process.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The method or process for recovering oil and grease from oily or greasy rags
and the cleansing and bleaching of such rags and waste as set forth.
