I, LOUIS CHARLES REESE, of Tachbrook Street, Pimlico, London, Doctor of
Philosophy, do hereby declare the nature of this invention to be as follows:-
This invention relates to the extraction or separation from liquids of matters
therein contained or to the purification of liquids by the extruction or separation
therefrom of matters desired to be removed, and has reference to the attainment
of such object by the method in which a liquid of different specific gravity than
and non-miscible with that to be treated and suitable to the obtainment of the
desired result is used as the extracting or purifying agent, the object of the
invention being, by the improved means hereinafter described, to enable the
treatment to be carried out as a continuous process, (in lieu of intermittently as
hitherto,) whereby the time required for and the cost of the treatment aro
materially lessened and the treatment is under better control and is improved
generally.
To this end, in carrying out the invention, I employ an extraction or separat-
ing chamber wherein the meeting plane of the liquid to be treated and of the
extracting liquid can be maintained at any desired level. The chamber may
be made of any suitable form and of any required dimensions and capacity, but
is preferably cylindrical in shape and vertically arranged.
At an upper part, the chamber is fitted with an inlet pipe leading from a
reservoir of the heavier liquid and fitted with means of controlling the inflow of
such liquid and terminating, within the upper part of the chamber, in a coil
which is perforated to allow of the emission of such liquid in a finely divided
state into the chamber.
At a lower part, the chamber is fitted with an inlet pipe leading from a reser-
voir of the lighter liquid and fitted with means of controlling the inflow of
such liquid and terminaling, within the lower part of the chamber, in a coil
which is perforated to allow of the emission of such liquid in a finely divided
slate into the chamber.
At the top, the chamber is fitted with an outlet pipe which, when the extract-
ing or purifying agent consists of the lighter fluid, serves for the escape thereof
together with the matter it has extracted from the liquid under treatment, and,
when the extracting or purifying agent consists of the heavier liquid, serves for
the escape of the purified liquid, the pipe being fitted with means of controlling
the outflow of the issuing liquid.
And, at the bottom, the chamber is fitted with an outlet pipe which, when the
purifying agent consists of the lighter liquid, serves for the escape of the liquid
from which the required matters have been extracted, and, when the purifying
agent consists of the heavier liquid, serves for the escape thereof together with
the matters it has abstracted from the liquid under treatment, the pipe being
fitted with a stop-cock, and its outlet end being raised to such a height as to
0177

page_text: determine the meeting plane of the respective liquids within the chamber at the
required level, and being, at such end, fitted with means of controlling the outflow
of the issuing liquid.
By such various pipes and cocks, I am enabled to regulate the flow of the
respective liquids into and out of the extracting chamber, and their passage
therethrough in opposite directions, as may be required according to the circuni-
stances of any particular case.
Within the upper part of the chamber and below the coil by which the heavier
liquid is supplied to the chamber, I may arrange a series of agitating blades
carried by a suitably supported shaft, which passes out of the chamber through u
stuffing-box and may be rotated by any convenient means.
The modus operandi of the improved apparatus is 118 follows;
Assuming the chamber to be charged with a body of the heavier liquid (as the
liquid to be purified) at its lower part, supporting a body of the lighter or
purifying liquid and the meeting plane of such liquids to be at the required
level intermedinte of the upper and lower coils and all said cocks to be open,
the heavier liquid enters the chamber through the top perforated coil in fine
streams which emerge directly into the body of the lighter liquid and slowly
descend therethrough until, in a partly purified condition, it reaches the body of
the heavier liquid and then assimilates therewith, while a corresponding portion
of the heavier liquid escapes at the bottom outlet of the chamber; meanwhile,
the lighter liquid enters the chamber through the bottom coil in fine streams
which emerge directly into the body of the heavier and partly purified liquid
and slowly ascend therethrough, completing the desired extraction or purification
thereof, until, in a partly charged condition, it reaches the body of the lighter
liquid, wherein the agitator is or may be slowly rotating, and then assimilates
therewith, while a corresponding portion of such liquid together with the matters
it has extracted from the heavier liquid escapes from the top outlet of the chamber.
The liquid to be purified is thus firstly acted on by the purifying liquid when
the latter is in a partly charged condition, and then, when partly purified, its
purification is completed by its being acted upon by the purifying liquid in a
fresh condition.
The improved apparatus is applicable to a great number of industrial opera-
tions in which such a separating, extracting or purifying action is carried out
by the agency of a suitable liquid of different specific gravity than and non-
miscible with the liquid to be treated, and is of special advantage in enabling
such operations to be carried on continuously, in lieu of intermittently as hitherto,
and, consequently, at a considerable reduction of time and cost.
By way of example, it may be mentioned that a series of such chambers and
apparatus respectively adapted to operate in manner aforesaid may be combined
as a battery suitable for the treatment and purification of oils.

and the other in a charged state, substantially as hereinbefore described.

and which can be so regulated as only to allow of the same quantity of the
heavier liquid leaving the chamber as the cock, b', allows to enter the same.
Perforated diaphragms, g, may be arranged within the chamber to facilitate
the separation of the liquids.
By such various pipes and cocks, I am enabled to regulate the flow of the
respective liquids into and out of the chamber and their passage therethrough
and through each other, as may be required according to the circumstances of
any particular case.
Within the chamber and between the coils,,, I may arrange any con-
venient agitating device, that represented consisting of vanes, d, carried by a
suitably supported shaft, d, which passes out of the chamber through a stuffing
box, d, and is rotated by gearing, ³.
The modus operandi of the improved apparatus is as follows: Assuming
the chamber to be charged with a body of the heavier liquid (as the liquid to be
treated) at its lower part supporting a body of the lighter or treating liquid,
and the meeting plane, X, of such liquids to be at the required level, intermediate
of the coils, b, c, and said cocks to be open to the required extent; the heavier
liquid enters the chamber through the top coil, 63, in fine streams which emerge
directly into the body of the lighter liquid and slowly descend therethrough,
until, 'in a nearly completely treated state, it reaches the body of the heavier
liquid and assimilates therewith, while a corresponding portion of such liquid
escapes from the chamber by the outlet pipe, meanwhile, the lighter liquid
enters the chamber through the bottom coil, c, in fine streams which emerge
directly into the body of the heavier and nearly treated liquid and slowly ascend
therethrough (completing the desired treatment thereof) until, in a partly
charged state, it reaches the body of the lighter liquid and assimilates therewith,
while a corresponding portion of such liquid together with the matters it has
extracted from the heavier liquid escapes from the chamber by the outlet pipe, o
The improved apparatus is applicable to various industrial operations in which
such a separating, extracting or purifying action is required, and, in such appli-
cations, a connected series or battery of any required number of such chambers
and a series of extracting liquids may be used, according to the particular indus-
trial application of the invention.
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..
In apparatus for extracting or separating from liquids chemical products or
matters dissolved cliemically fixed or finely divided in suspension therein, by
liquid (a liquid or a series of liquids) of different specific gravity than and non-
miscible with the liquid to be treated and suitable to the attainment of the.
desired result; — -au extracting or separating chamber (or a connected series
thereof, each) adapted with inlet pipes for the liquid to be treated and for the
treating liquid, outlet pipes for the treated liquid and for the treating
liquid and extracted matters, means for dispersing the liquid to be
treated into the body of the partly charged treating liquid, and means for dis-
persing the treating liquid into the body of the partly or nearly treated liquid ;-
such parts being so arranged as that the liquid to be treated and the treating
liquid are balanced in the chamber in superposed relation, and as that the
meeting plane of such liquids is caused to be maintained at any required level
intermedinte of the inlets of the respective liquids both during the operation of
the apparatus and when the apparatus is at rest and charged with liquid, and
as that each such liquid is caused to pass in a minutely divided condition
through the body of the other liquid, so that the liquid to be treated is firstly
acted on while passing in a finely divided condition through the body of the
treating liquid in a partly charged state, and, after thus pag therethrough

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to the extraction or separation from liquids of chemical
products or matters dissolved chemically fixed or finely divided in suspension
therein, and to the attainment of such result by an improved application of the
method in which liquid of different specific gravity than and non-miscible with
the liquid to be treated and suitable to the attainment of the desired result is
used as the extracting, separating or purifying agent (hereinafter referred to as
the "treating liquid"); the object of the invention being, by the improved means
hereinafter described, to enable the treatment to be carried out in a continuous
and automatic manner, whereby the time required for and the cost of the treat-
ment are lessened and the treatment is rendered more effective.
To this end, the invention consists in an extraction chamber (or chambers)
so adapted as that the liquid to be treated and the treating liquid are caused to
be balanced therein in superposed relation in respect to a meeting plane which
is automatically caused to be maintained at any required level intermediate of
the inlets of the respective liquid's both during the operation of the apparatus
and when the apparatus is at rest and charged with liquid, and as that each
such liquid is caused to pass in a minutely divided condition through the other
liquid in bulk, so that the liquid to be treated is firstly acted on while passing
in a finely divided condition through the body of the treating liquid in a partly
charged state, and, after thus passing therethrough and itself collecting in bulk,
is finally acted on and has its treatment completed by the treating liquid in a
fresh state being passed in a finely divided condition through its collected bulk
or body, the respective liquids being caused to flow through the chamber in
opposite directions and regulated quantities, and to respectively issue therefrom
separated from each other, the one in a completely treated state and the other
in a charged state, as hereinafter more fully described.
The accompanying drawing represents a sectional elevation of the improved
apparatus showing the same in action:
a, represents the extraction chamber, which may be made of any suitable form,
dimensions and capacity, but is preferably cylindrical in cross section and ver-
tically arranged.
At an upper part, the chamber is fitted with an inlet pipe, b, leading from a
reservoir of the heavier liquid (which may be the treating liquid or the liquid
to be treated) and fitted with means, b, of controlling the inflow of such liquid,
and terminating, within the upper part of the chamber, in a perforated coil, b,
from which the liquid escapes in a finely divided state into the chamber.
At a lower part, the chamber is fitted with an inlet pipe, c, leading from a
reservoir of the lighter liquid (which may be the liquid to be treated or the
treating liquid) and fitted with means, c', of controlling the inflow of such liquid,
and terminating, within the lower part of the chamber, in a perforated coil, ³,
from which the liquid escapes in a finely divided state into the chamber. Other
equivalent liquid dispersing devices may be used in lieu of the coils, h², c³.
At the top, the chamber is fitted with an outlet pipe, e³, which, when the
treating liquid is the lighter liquid, serves for the escape thereof together with
the matter it has extracted from the treated liquid, and, when the treating liquid
is the heavier liquid, serves for the escape of the treated liquid.
And, at the bottom, the chamber is fitted with an outlet pipe, &, which, when
the treating liquid is the lighter liquid, serves for the escape of the treated
liquid, and, when the treating liquid is the heavier liquid, serves for the escape
thereof together with the matter it has extracted from the treated liquid, the
outlet of the pipe being upraised and arranged to determine and regulate the
meeting plane of the respective liquids within the chamber at the required level.
If but a single chamber be used, the regulation of the height of the meeting
plane of the two liquids may be made by a cook, bt, applied to the pipe b³,
