PROVISIONAL SPECIFICATION.
A New Apparatus for Removing, Purifying, and Freeing Noxious
Gases and Vapours from Public and Private Sewers, Tunnels,
Mines, Factories, Buildings, and all Places Containing Impure
Gases.
GEORGE SMITH Gas Engineer 27 Anley Road, W. Kensington Park Hammersmith
Middlesex do hereby declare the nature of this invention to be as follows:-
:-
For the purpose of removing the noxious gases from the public sewers or any
places containing foul vapours 1 use two gas holders and two tanks of any suitable
size and sufficient strength with their proper lifting gear, to be placed conveniently
near the sewer, into each of the holders I insert a pipe or flue which descends through
the bottom of the tanks to the main sewer the end of each pipe or flue is above the
level of the liquid contained therein. The holders working automatically exhaust or
suck out the sewerage gas, which is admitted through a system of reversing cocks
which are arranged for inlet and outlet. The holders alternately filling and emptying
themselves of the gas so sucked out, pass the same through a properly prepared and
constructed blast furnace fitted with an air-tight door, discharging the so purified gas
into the atmosphere through a suitable shaft. By this means I claim that the fouling
of the atmosphere is entirely prevented without any prejudice to health. I also use
to aid the working of the two holders a small gas or any other kind of engine. By this
Invention I claim to improve and simplify the removal, purifying and freeing of noxious
gases and vapours from all places containing the same.

A New Apparatus for Removing, Purifying, and Freeing Noxious
Gases and Vapours from Public and Private Sewers, Tunnels,
Mines, Factories, Buildings, and all Places Containing Impure
Gases.
I GEORGE SMITH 27 Anley Road West Kensington Park, W. Hammersmith in the
County of Middlesex Gas 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 :-
This invention relates to a new apparatus for removing, purifying, and freeing
noxious gases, and vapours from public, and private, sewers, tunnels, mines, factories,
buildings, and all places containing impure gases, the apparatus being always similar
the dimensions only being changed.
To aid in explaining the nature of the invention I annex three sheets of drawings
shewing by way of example arrangements of apparatus according thereto.
Fig. 1. represents a vertical section through the centre of the apparatus.
Fig. 2. is an end elevation of rack and frame of apparatus.
Fig. 3. is a plan of apparatus.
Fig. 4. is an elevation of double flap in flushing well in connection with main
sewer.
Fig. 5. is a detail view showing section of double flap in connection with surface
gulleys.

with sewer.

page_text: The apparatus comprises two receivers A A (Fig. 1.) working into two sealed
tanks B B supported by columns Z Z.and guides with balance weights and chains
for the receivers pulleys zz to work against. The receivers alternately filling and
emptying themselves by the arrows C ("connected by flushing well D (Fig. 6.) with
the sewer at E by a double flap set on an india rubber seat e e¹.
To aid the working of the receivers A A (Fig. 1) a chain is provided working
over pulleys F F and double lug wheel G balanced by compensating weights H H.
The bridge II supported on columns Z Z carries pulleys F F and double lug
wheel G.
The fixed driving pulley N to which is attached the driving bands is driven by a
small gas, compressed air, steam, electric engine or any other motive power which may
be convenient. This engine sets in motion the reversing cocks K K K K by means of
levers which leavers are worked by the reversing rod and crank L L attached
to the slide bar M and fork m, also a train of wheels consisting of driving spur and
pinion wheels O, a slotted rack P working in the slide P secured to the framework Q
the distance regulated by sliding blocks R.
This train of wheels by means of reversing gear n and band passing over the
reversing lug wheel G connected by chains and pulleys F F aid in lifting the two
receivers A A as the receivers alternately fill and empty with the sucked out gases
from the sewers. The four reversing cocks K K K K are connected with the exhaust
pipe CC leading to the flushing well D (Fig. 6).
The inlet pipe S leading to hot air chamber constructed round the furnace over
which the foul gases are consumed before passing out through the shaft into the
open air.

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 new apparatus for removing, purifying, and freeing noxious gases, and
vapours from public, and private sewers, tunnels, mines, factories, buildings, and all
places containing impure gases.
(2.) The combination of two receivers A A working automatically into sealed
tanks B B by means of pulleys F F and double lug wheel G balance weights and
chains H H driven by a small gas engine or any other motive power which may be
convenient. The two receivers A A alternately filling, and emptying themselves of
the foul gases which they exhaust from the sewers through pipes CC to which are
attached four reversing cocks K K K K with leavers kkkk arranged for inlet and
outlet as the receivers A A rise and fall passing the foul gas by means of the centre
pipe S through an air chamber U running round a properly constructed blast

page_text: furnace purifying the sewer gases, and passing the same into the atmosphere through
a tall shaft as described above with reference to the annexed illustrated drawing.
(3.) The arrangement of the flushing well D in connection with the exhaust
pipe CC with its air tight top, and suction pipe X and double flap door e e¹ connected
with the sewer E the arrangement being such as to allow the foul gases to be
sucked out by the auxillery small pipe X at the same time as the flushing operation is
taking place, effectually by this means preventing the unscaling of traps and gulleys.
as described with reference to the drawing.
(4.) Providing an intermediate shaft to which a rigger is fixed to drive the
band N over the rigger N next to the spur wheel Oas hereinabove described with
reference to the annexed illustrative drawing.
