Improvements in Apparatus for Extracting Oil from Dirty Waste.
I, JAMES HEYWOOD, of 369, Ashton New Road, Clayton, Manchester, in the
County of Lancaster, Chemical Manufacturer, do hereby declare the nature of
this invention to be as follows:-
In carrying out my invention I employ a pan having a false perforated bottom
into which pan I put the waste to be treated and cover the same with a perforated
plate, the pan is provided with a cover held in position with bolts in the usual
manner. The bottom cavity of this pan formed by the false perforated plate is
provided with an inlet connected to a pump for the purpose hereinafter described.
I also provide an outlet from the cavity formed by the top perforated plate which
outlet is is communication by a pipe with a closed cavity rectifier which closed
cavity rectifier is intended to be heated with steam as hereinafter described,
and this closed cavity rectifier is also provided with an outlet which outlet is in
communication with a worm or coil of pipes contained in a tank which tank is
intended to be supplied with cold water as required the outlet from the worm
or coil being led away to a receiver or well as desired.
The action of this apparatus is as follows:-
I first fill the receiver or well with bi-sulphide of carbon which I cover with
water to prevent evaporation of the bi-sulphide of carbon and then charge the
pan with the waste which is to be treated and secure the same by the bolted cover
when I start the pump which forces the bi-sulphide of carbon through the waste
and such bi-sulphide of carbon becoming amalgamated with the oil contained in
such waste the bi-sulphide of carbon and oil are both driven forward through
the pipes provided, into the closed cavity rectifier which closed cavity rectifier
is heated by steam and such heat will then convert the bi-sulphide of carbon
into vapour which vapour is then driven forward through suitable pipes into
and through the worm or coil where by the action of the cold water in the tank
it is reconverted into liquid and from which worm or coil it is led away into
the receiver or well ready for use over and over again. The waste is then
removed from the pan which is then ready for another charge. The oil remain-
ing in the closed cavity rectifier is withdrawn through an outlet provided from
time to time as required. It will now be seen that if I construct the apparatus
in series the operation may be continuous.

I, JAMES HEYWOOD, of 369, Ashton New Road, Clayton, Manchester, in the
County of Lancaster, Chemical Manufacturer, do hereby declare the nature of
[Price 8d.]

page_text: this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
In carrying out my invention I employ a pan having a false perforated bottom
into which pan I put the waste to be treated and cover the same with a perforated
plate, the pan is provided with a cover held in position with bolts in the usual 5
manner. The bottom cavity of this pan formed by the false perforated bottom is
provided with an inlet connected to a pump for the purpose hereinafter described.
I also provide
an outlet from the cavity formed by the top perforated plate which
outlet is in communication by a pipe with a closed cavity rectifier which closed
cavity rectifier is intended to be heated with steam as hereinafter described
and this closed cavity rectifier is also provided with an outlet which outlet is in
communication with a worm or coil of pipes contained in a tank which tank is
intended to be supplied with cold water as required the outlet from the worm
or coil being led away to a receiver or well as desired. From the bottom of the
worm or coil I further take a pipe to near the bottom of a small tank of water!
which overflows into the well by means of a pipe. This small tank is also
provided with an escape pipe for the gas escaping by the pipe from the coil which
gas is met by a stream of water coming down the escape pipe for the purpose of
purifying such gas.
In order that my invention may be readily understood and carried into effect
I have annexed a sheet of drawings in which Fig. 1, is an elevation and Fig. 2
is a plan of my improved apparatus and in the following description like letters
are used in both views to denote like parts.
I employ a pan A having a false perforated bottom B and into this pan A I put
the waste to be treated and cover the waste with a perforated plate Ċ the pan A
is provided with a cover D held in position with bolts in the usual manner.
The cavity E of this pan A is provided with the inlet F_connected to the pump G
by the pipe H for the purpose hereinafter described. I also provide an outlet I
from the cavity J which outlet is in communication by a pipe K with a closed
cavity rectifier L which closed cavity rectifier L is intended to be heated with
steam by the pipe M and this closed cavity rectifier L is also provided with an
outlet N which outlet N is in communication with a worm or coil of pipes O
contained in a tank P which tank P is intended to be supplied with cold water
as required the outlet Q from the worm or coil O being led away to a receiver
or well R as desired. From the bottom of the worm or coil 0 I further take a
pipe S to near the bottom of a small tank T of water which overflows into the
well R by means of the pipe U. This small tank T is also provided with an
escape pipe V for the gas escaping from the worm or coil O and such gas is met
by a stream of water coming down the escape pipe V from the pipe X for the
purpose of purifying such gas.
The action of this apparatus is as follows:-
I first fill the receiver or well R with bi-sulphide of carbon which I cover with
water to prevent evaporation of the bi-sulphide of carbon and then charge the
pan A with the waste which is to be treated and secure the same with the bolted
cover D when I start the pump G which forces the bi-sulphide of carbon through
the waste contained in the pan A and such bi-sulphide of carbon becoming
amalgamated with the oil contained in the waste the bi-sulphide of carbon and
oil are both driven forward through the pipe K into the closed cavity rectifier L
which closed cavity rectifier L is heated by steam and such heat will then convert
the bi-sulphide of carbon into vapour which vapour is driven forward through
the pipe into and through the worm or coil O where by the action of the cold
water in the tank P the bi-sulphide of carbon is reconverted into liquid and from
this worm or coil it is led away by the pipe Q into the receiver or well R for
use over and over again. The pipe S and tank T are provided for the purpose
of condensing the vapour which has a tendency otherwise to remain in the coil O
the pipe U conveying such condensed vapour back into the receiver or well,

page_text: the gas escaping at pipe S being allowed to ascend into the atmosphere by the
escape pipe V.
Upon all the amalgamated oil and bi-sulphide of carbon becoming discharged
into the closed cavity rectifier L I discharge the liquid remaining in the pan A
into the well and then admit steam by the pipe a into such pan A which converts
the bi-sulphide of carbon remaining in the waste into vapour which is led into
the coil by the pipe Y where it is reconverted into liquid and discharged into
the well R.
The waste is now removed from the pan A which is then ready for another
charge.
The oil remaining in the closed cavity rectifier L is withdrawn through the
outlet W from time to time as required. It will be apparent that any number
of pans A may be used to enable the work to be continuous.
Having now particularly 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 combination and arrangement of apparatus substantially as and for the
purposes herein before described and illustrated on the accompanying drawing.
