1, WILLIAM THOMAS WALKER, of Bishopswood Road Highgate in the County of
Middlesex, Esquire, do hereby declare the nature of this Invention to be as follows:-
My Invention relates to distillatory apparatus in which liquors are subjected to
the action of steam heat whilst the said liquors are flowing from chamber to chamber
of a superposed series arranged in the form of a column. Hitherto such chambers
have consisted of shallow compartments provided with partitions affording openings
or passages for the liquor alternately at opposite ends and provided with overflow
pipes or passages for the passage of the liquor from vessel to vessel the liquor taking
a backward and forward course through the apparatus between the said partitions.
Under each of the shallow compartments are steam casings for heating the liquors and
driving off their volatile matters such for example as in treating ammoniacal gas
liquors in what is known as the closed vessel process of purifying coal gas. This
apparatus so constructed is expensive to make and inconvenient in use and it is the
object of my Invention to provide an apparatus cheap to make and very efficient in
operation.
According to my Invention I provide the chambers through which the liquors pass
each with a raised partition giving a course or channel in the form of a volute or
spiral so that the liquors fed in (say at the side) will take a spiral course continuously
in the same direction. The outlets for the liquor from chamber to chamber may be
made so that the liquors pass in alternately opposite directions in adjacent chambers
or so that the liquors are led out of the centre of one chamber into the outward part
of the volute or spiral of the chamber next below it.
In order to economize heat the column of chambers may be surrounded by a
casing with felt or other non-conductor of heat between its interior and the exterior
of the column. The said outer casing may be hinged (preferably by a vertical
hinge) or arranged so that it can be readily opened out completely to get at any of
the chambers.

Improvements in Distillatory Apparatus for Use in Chemical
Operations.
I WILLIAM THOMAS WALKER of Bishopswood Road Highgate in the County of
Middlesex Esquire do hereby declare the nature of this Invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:—
My Invention relates to distillatory apparatus in which liquors are subjected to the
action of steam heat whilst the said liquors are flowing from chamber to chamber of
a superposed series arranged in the form of a column. Hitherto such chambers have
consisted of shallow compartments provided with partitions affording openings or
passages for the liquor alternately at opposite ends and provided with overflow pipes
or passages for the passage of the liquor from vessel to vessel the liquor taking a
backward and forward course through the apparatus between the said partitions.
Under each of the shallow compartments is a steam casing for heating the liquors
and driving off their volatile matters such for example as in treating aminoniacal gas
liquors in what is known as the closed vessel process of purifying coal gas. This
apparatus so constructed is expensive to make and inconvenient in use and it is
the object of my Invention to provide an apparatus cheap to make and very efficient
in operation.
According to my Invention I provide the chambers through which the liquors pass
each with a raised partition giving a course or channel in the form of a volute or
spiral so that the liquors will in each chamber take a spiral course continuously in the
same direction. The outlets for the liquor from chamber to chamber may be made so
that the liquors pass in alternately opposite directions in adjacent chambers or so that
the liquors are led out of the centre of one chamber into the outward part of the
volute or spiral of the chamber next below it.
The accompanying drawing shows an arrangement according to my Invention.
Figure 1 being a vertical section of part of a column. Figure 2 a plan of one
chamber and Figure 3 a plan of that next below it. A, B, are the compound chambers
forming the sections of which the column is built up. A are the chambers through
which the liquors pass the floor of each such chambers being provided with a raised
partition a in the form of a volute or spiral and B are the spaces beneath the floors
of the chambers into which steam is admitted from the steam pipe C by branches c
the water of condensation being drawn off by the pipes d communicating with the
main pipe D.-E are the passages through the centre of the apparatus by which
the gases pass from each chamber A to the next above it and to the outlet. are
the tubes by which the liquor descends from each chamber A. to the next chamber A
below it and to the discharge from the lowest chamber A. The floors of the
chambers A are shown as being alternately somewhat inclined inwards and out-
wards for the flow of the liquid although this may be provided for by the level

page_text: to which the tubes open into the chambers A. The tubes are alternately at
the inward and outward ends of the spiral passages so that the liquor flows out-
ward and inwards alternately.
In order to economize heat the column of chambers may be surrounded by a
casing g with felt or other non-conductor of heath between its interior and the
exterior of the column. The said outer casing may be hinged (preferably by a
vertical hinge) or arranged so that it can be readily opened out completely to
get at any of the chambers.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In distillatory apparatus of the kind described chambers through which the
liquors pass with a course or channel in the form of a volute or spiral substantially
as herein before described.
2. The distillatory apparatus arranged or constructed as illustrated in the
accompanying drawings.
