Improvement in or relating to Apparatus for Scrubbing and Filtering
Gas.
WILLIAM GEORGE WILLIS, 35, Beaumont Street, Stapleton Road, Bristol,
Boilermaker, do hereby declare the nature of this invention to be as follows:―
This invention consists of improvement in or relating to apparatus for scrub-
bing and filtering gas such as water gas, producer gas, oil gas, or a combination
or mixture of such gases. In carrying my invention into effect I provide an
outer chamber in which is placed an inner chamber so arranged that the gas
first enters the outer chamber and thence passes into the inner chamber.
This inner chamber is provided with trays or holders for filtering materials
such as saw dust; these trays are so arranged that they may be withdrawn
when required for the purpose of recharging through suitable doors or openings.
Suitable plates are provided and so arranged in this chamber as to cause the
gas to pass through the filtering material. The outer chamber is provided with
coke or other substance through which the gas passes before it enters the inner
chamber. Of course it will be understood that I do not confine myself to the
exact arrangements of the various parts described.

Improvement in or relating to Apparatus for Scrubbing and Filtering
Gas.
WILLIAM GEORGE WILLIS, 35, Beaumont Street, Stapleton Road, Bristol,
Boilermaker, 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: —
This invention consists of improvements in or relating to apparatus for scrub-
bing, and filtering gas such as water gas, producer gas, oil gas, or a combination
or mixture of such gases. In carrying my invention into effect I providé an
outer chamber in which is placed an inner chamber so arranged that the gas
first enters the outer chamber, and thence passes into the inner chamber.
This inner chamber is provided with trays or holders for filtering materials
such as saw dust & these trays are so arranged that they may be withdrawn

page_text: when required for the purpose of recharging through suitable doors or openings,
suitable plates are provided for and so arranged in this chamber as to cause the
gas to pass through the filtering material. The outer chamber is provided with
coke or other substance through which the gas passes before it enters the inner
chamber. Of course it will be understood that I do not confine myself to the
exact arrangement of the various parts described.
For purposes of illustration, I will now refer to the annexed drawings in
which
Figure 1, is a sectional side elevation shewing my invention.
Figure 2, section through line -y in Figure 1.
Figure 3, is a vertical section through line ay in Figure 2.
Referring to Figure 1, a is an outer chamber in which the inner chamber
casing is carried. The outer chamber a is packed with coke or such suitable
material & the gas enters through the aperture c. After passing through the
coke or other material it passes through the inner chamber or casing. This
inner chamber or casing carries the trays or holders . These trays or holders i
are provided with a suitable filtering material such as sawdust . j is a plate
so arranged as to depend or enter the saw dust in the tray or holder i a sufficient
distance for the purpose of ensuring the gas passing through a layer of saw dust.
The course which the gas takes is indicated by the arrows as shewn and after
having passed through the various layers of filtering material it will enter the
exit & from which it will be conveyed to any suitable position.
The trays are so arranged that they may be withdrawn when required for
the purpose of recharging as will be seen, g being suitable doors for enabling
them to be withdrawn from the inner chamber. The bottom doors e will enable
the coke or other material to be withdrawn from the outer chamber when
required. The top covers f upon the outer chamber will facilitate the recharging
of the apparatus. These may be of any suitable form. The perforated plate h
is for the purpose of spreading or distributing the gas. By this invention it is
possible to clean or renew the filtering material without entering the apparatus
or necessarily inhaling the gas or fumes therein.
Having now particularly described and ascertained the nature of my said
invention, and the manner in which same is to be performed, I declare that what
I claim is:
1. The gas scrubber or purifier, substantially as described, and illustrated
herein, and for the purpose set forth.
2. In gas scrubbing or purifying apparatus an outer casing, having apertures
for the passage of gas to the interior, an inner casing carrying sliding trays,
dividing plates or partitions adapted to cause the gas to pass through suitable
filtering material carried in said trays, an inlet and outlet pipe so arranged, that
the gas passes through a packing of coke or other suitable substance, carried
between the outer & inner case, & thence through the filtering material, carried
in the trays aforesaid, and then to the outlet, substantially as described & illus-
trated herein, and for the purpose set forth.
