PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing or Scrubbing Gas.
I, JOSIAH CLEMENT CHANDLER, of 223, Brixton Road, Brixton, in the County
of Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
..
My invention relates to apparatus for washing or scrubbing gas and especially to
apparatus of the kind described in the Specification of Letters Patent No. 7691
of 1888 in which is employed a series of bundles of laths nailed or otherwise secured
together.
The object of this invention is to simplify the construction of such bundles and to
this end it consists in forming each bundle of a number of boards having therein a
number of saw cuts or slits, thus affording a large amount of surface which can be
wetted and against which the gas to be purified can impinge.
In practice the saw cuts advantageously extend from the two ends of the board
towards the centre thereof, an unent portion being however left at the centre in
order to retain cach board in one piece. In making up the bundles suitable distance
pieces are placed between the boards.
My improved form of bundle is very advantageously used in connection with
washing and scrubbing apparatus of the kind described in the Specification of former
Letters Patent No. 422 of 1877.
Dated the 26th day of June 1891.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Washing or Scrubbing Gas.
I, JOSIAH CLEMENT Chandler, of 223, Brixton Road, Brixton, in the County
of Surrey, Engineer, 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 or scrubbing gas and especially to
apparatus of the kind described in the Specification of Letters Patent No. 7691
of May 25 1888 in which the wetted surfaces against which the gas-impinges are
composed of bundles of laths.
According to my invention instead of employing laths I make use of boards
having therein a number of saw-cuts or slits for affording a large amount of wetted
surface.
In practice a number of such boards are advantageously made up into a bundle,
suitable distance-pieces being placed between them.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawings, in which :-
Figures 1 and 2 are side and end views respectively, of a bundle of my boards
adapted for use in gas washing or scrubbing apparatus of the kind in which the gas
passes horizontally through the same, as for instance in the apparatus described in
the Specification of British Letters Patent No. 422 of 1877.
Figure 3 is a sectional elevation shewing how the said bundle may be held in
position in the washing apparatus; and,
Figure 4 is a section on the line 7. Figure 3.

page_text: Figures 5 and 6 age views similar to Figures 1 and 2 respectively shewing the
arrangement of the boards when the gas is caused to pass through them from the
centre towards the periphery, for instance as described in the Specification of
Letters Patent No. 4928 of 1877.
Figures 7 and 8 are a sectional elevation and a longitudinal section shewing how
the bundles in this case may be held in position.
Similar letters of reference indicate corresponding parts in the several figures.
a, a indicate. the boards, b, b the slits or saw-cuts therein, , c the distance-pieces
between the boards, and d, d bolts passing through the boards and through the
distance-pieces and serving to clamp the whole together.
In practice I advantageously arrange a series of segmentally shaped bundles,
such as are shewn in Figure 1 and in Figure 5 to form discs, which are caused
to revolve in order to retain the surfaces properly wetted, in the usual well known
manner.
When the gas is to pass through the bundles in a horizontal direction the boards
are arranged as shewn in Figures 1 and 2, that is to say, side by side, so that the
gas will pass through the various slits in the boards.
As shewn in Figures 3 and 4 several bundles are clamped between pairs of arms e, e
to form a disc, the said arms being secured at their inner ends to a hub or boss f
and at their outer ends connected by plates g, g, h, are cross-bars bolted between
the plates g, g on opposite sides of the bundles in order to retain the said bundles in
their proper positions between the arms.
In the arrangement shewn in Figures 5 and 6 which is adapted for use when
the gas passes radially through the bundles forming the disc, the said bundles are
advantageously carried, between two metal plates i, i and held in place by cross-
bars j, j and bolts k, as shewn in Figures 7 and 8.

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. Apparatus for washing or scrubbing gas in which the wetted surfaces against
which the gas impinges are formed of boards having saw-cuts or slits therein,
substantially as, and for the purpose, described.
2. In apparatus for washing or scrubbing gas a series of bundles composed of
boards having saw-cuts or slits as described and for the purpose specified.
3. The manufacture and use of the improved bundles for gas washing or scrubbing
apparatus herein before described and illustrated in the accompanying drawings.
