PROVISIONAL SPECIFICATION.
Improvements in Gas Cleansing Apparatus.
I, JOHN SPURGE of 29, Walpole Road, Walthamstow, in the County of Essex
Traveller; do hereby declare the nature of this Invention to be as follows:-
Gas washers consisting of vessels divided into compartments are usually provided
with plates, brushwood perforated sheet metal, and other devices which pass
through the washing liquid in the vessel and present a wetted surface to act upon
the gas.
My improvement as applied to such washers consists in constructing the washing
surfaces of wicker-work of a form suited to the position in which they are to operate,
the wattled structure of the wicker-work having a most efficient action in retaining
the water and presenting a continuously wetted and extended surface to contact
with the gas whereby the extraction of the ammonia from the gas is rendered much
more complete.
My Invention also comprises the employment of wicker-work diaphragms
superposed in vertical cylinders and moistened by water showered upon them from
above.
In both forms of the apparatus referred to, the wicker-work washing surfaces are
more efficient and much cheaper than those now used.

Improvements in Gas Cleansing Apparatus.
I, JOHN SPURGE, of 29, Walpole Road, Walthamstow, in the County of Essex,
Traveller, 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 apparatus for washing and scrubbing gas, and consists in
constructing the washing surfaces of wicker-work, the wattled structure of which
I have found by experiment has a most efficient action in retaining the water and
presenting a continuously wetted surface for contact with the gas, whereby the
washing and scrubbing of the gas is rendered more complete than when wetted
surfaces formed of plates, brushwood, perforated sheet metal or other devices are
employed.
My improvements are applicable to washer scrubbers of the kind in which the
washing vessel is arranged horizontally and provided with a series of compartments

page_text: in which the surfaces to be wetted rotate, or to vertical scrubbers in which the water
is showered upon the surfaces.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a vertical section of one of the compartments of a horizontal washer
provided with wicker-work washing surfaces in accordance with my invention.
Figure 2 is a section at right angles to Figure 1.
Figure is an elevation shewing the wicker surfaces arranged in horizontal
layers; and,
Figure 4 is a plan of the same:
Figures 5 and 6 are views similar to Figures 3 and 4 respectively showing the
wicker-work arranged in vertical layers:
Figure 7 is a vertical section showing the application of my invention to a vertical
washer; and,
Figure 8 is a plan view of one of the wicker-work diaphragms of such washer.
Similar letters of reference indicate corresponding parts in the several figures.
a is the washing vessel and b, b are the pieces of wicker-work to be wetted. In
a horizontal washer of the kind shewn in Figures 1 and 2 a series of bundles c of
pieces of wicker-work are arranged in cylindrical form around a shaft in a well
known manner the said bundles being supported between discs d, d carried upon
the shaft and held in position between the said discs by cross bars or bolts e, e. The
several pieces of wicker-work in each bundle or section c may be arranged one
upon the other, as shewn in Figure 3, so that they form a series of layers practically
concentric with the shaft or they may be arranged vertically, as shewn in Figures 5
and 6, so that they form practically a series of parallel discs mounted upon the said
shaft. In either case the several pieces of wicker-work of which each bundle is
composed are bound together by metal or other bands f, f.
In a vertical scrubber a series of layers or diaphragins of wicker-work of
a shape corresponding with the shape of the tower in transverse section are
superposed, as shewn in Figure 7, the said layers in this case being represented as
being of circular shape as shewn in Figure 8. The wicker-work diaphragms are
maintained in a wetted condition by water introduced at the top of the tower
through the perforations of a plate g in the usual well known manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A gas washing or cleansing apparatus wherein the surfaces to be wetted and
in contact with which the gas passes are formed of wicker-work, substantially as
described.
2. A gas washing and scrubbing apparatus wherein a series of bundles of pieces
of wicker-work are arranged in a cylindrical form, substantially as described by
reference to Figures 1 to 6 of the drawings.
3. A vertical gas washing apparatus wherein a series of superposed diaphragms
or pieces of wicker-work are arranged in a tower, substantially as described by
reference to Figures 7 and 8 of the drawings.
