This invention relates more especially to the cotton waste tordinarily used by
Engineers for the purpose of cleaning Steam Engines and other machinery and it
has for its object an improved process and composition for removing the oil absorbed
by such cotton waste after it has been used, and for effectually cleaning. it so that
it can be re-used for the same purpose.
For this purpose we take the oily and dirty waste which is to be treated, and
we submit it to sufficient pressure in a hydraulic or other press by which the oil is
extracted and collected. The waste is then immersed in a bath of the.mixture herein-
after described, in a suitable vessel, which is brought to boiling point and the
waste is stirred or kept in motion by means of any suitable appliances of the
ordinary kind, for a sufficient time, ordinarily about one hour but which may vary
more or less according to the character and condition of the waste.
The waste is then withdrawn and the liquid squeezed out, and it is then washed
in warm water until all traces of the cleaning liquid have been removed. It is then
dried by steam or other means in the usual way, and after drying it remains quite
clean and fit to be re-used.
The oil first extracted by pressure.as.described may be refined and used.

COMPLETE SPECIFICATION.
An Improved Process and Composition for Extracting Oil from and
Cleaning Cotton Waste.
We, WILLIAM MICHELL, of Penton Place, in the County of Middlesex, Manu-
facturer, and SALOMON PICARD of Notting Hill in the County of Middlesex,
Laundryman, do hereby declare the nature of our 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)
Our invention relates more especially to the cotton waste ordinarily used by
Engineers and others for the purpose of cleaning Steam Engines and other machinery,
and it has for its object an improved process and composition for removing the oil
absorbed by such cotton waste after it has been used, and for effectually cleaning it so
that it can be re-used for the same purpose.
In order to put our invention in operation we take the oily and dirty waste which
is to be treated, and we first submit it to sufficient pressure in a hydraulic or other
press by which the oil is extracted and collected. The waste is then immersed in a
bath of the mixture hereinafter described, contained in a suitable vessel, the mixture
being brought to boiling point and the water is stirred or kept in motion by means
of any suitable stirring arms or appliances of the ordinary well known kinds
actuated by steam or other convenient power or by hand, for a sufficient time,
ordinarily about one hour but which may vary more or less according to the
character and condition of the waste. The waste is then withdrawn and after the
liquid contained in it has been squeezed out it is washed in warm water until all
traces of the cleaning liquid have been removed. It is then dried, by drying
machinery of any of, the ordinary well known kinds, by steam or by other means
in the usual way, and after drying it remains quite clean and fit to be re-used,
having been first opened or separated by any suitable means such as the opening
machines ordinarily used for cotton.
The oil first extracted by pressure as described may be refined and used.
In order to form the bath in which the waste is boiled as above described, we

page_text: A sufficient quantity, ordinarily about one pint but which may be varied more
or less of this composition or mixture is added to every 20 gallons of water in
order to form the bath first described.
The number and proportions of the several ingredients may be varied more or
less, and some of them may be omitted, or others of the like nature may be added or
substituted, according to the character of the waste which is to be cleaned, and of the
oil and dirt which it contains.
By the improved process and composition the cleaning of the waste is quickly and
economically effected, and the cleaned material is equal to and can be used in the
same way as new material.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. For cleaning cotton waste, the process consisting of first expelling the oil by
pressure, then immersing the waste in a bath prepared of the ingredients and in the
manner described, and after a sufficient time removing the waste and squeezing
out the liquid remaining in it, washing it in warm water, and drying it, substantially
as herein described.
2. The composition of materials to form the bath, substantially as herein described.
