page_text: I, ALFRED GEORGE RUMLEY, of Brookland House, Albany Road, Montpelier,
Bristol, Manager of Cabinet Works, do hereby declare the nature of said invention
for "AN IMPROVED SYSTEM FOR OBVIATING THE RETURN OF FOUL OR NOXIOUS
AIR AND GASES IN DRAIN PIPES AND SEWERS, AND FOR VENTILATING OR PURIFYING
THE ATMOSPHERE THEREIN," to be as follows:-
This invention relates to an improved system of sewerage and is designed to
prevent the return of foul or noxious air, gases and effluvia from soil or drain pipes
or sewers into chambers, houses and other places with which they are connected.
It is also designed to effect the purification of the atmosphere of soil or drain
pipes or sewers by introducing therein, under pressure, a supply or current of fresh
atmospheric air.
To prevent the return of foul or noxious air; gases and effluvia, valves which
open outwards only, are fitted in the syphons of soil or drain pipes, or in the said
pipes, or in the sewers at such points as may be convenient and desirable. The
normal tendency of the valves is to remain closed, but this tendency is overcome by
the flow of the sewage which, when being discharged, forces the valves open.
After the sewage has passed the valves close in succession and fitting closely into
their seats prevent the return of any foul or noxious air, gas or effluvia.
For the purpose of purifying the pipes, drains or sewers, connection at convenient
points is made between them and air pumps or other blowing apparatus. By these
means a supply of air may be at any time forced into the pipes, drains or sewers,
or a current of air may be maintained so long as may be desirable therein, it being
understood that the air thus supplied is directed into the pipes drains or sewers in
the direction of the flow of the sewage towards the points of discharge and, con-
sequently, in the direction in which the valves aforesaid are free to open. '.

Bristol, Manager of Cabinet Works, do hereby declare the nature of my said
Invention for "AN IMPROVED SYSTEM FOR OBVIATING THE RETURN OF FOUL OR
.NOXIOUS AIR AND GASES IN DRAIN PIPES AND SEWERS, AND FOR VENTILATING OR
PURIFYING THE ATMOSPHERE THEREIN," to be as follows:-
This Invention relates to an improved system of sewerage, and is designed to

or sewers into chambers, houses, and other places with which they are connected.-
It is also designed to effect the purification of the atmosphere of soil or drain pipes.
or sewers, by introducing therein under pressure a supply or current of fresh,
atmospheric air. To prevent the return of foul or noxious air or gases and effluvia,
valves which open outwards only are fitted in the syphons of soil or drain pipes or
in the said pipes, or in the sewers at such points as may be convenient and
desirable: The normal tendency of the valves is to remain closed, but this
tendency is overcome by the flow of the sewerage, which when being discharged,
forces the valves open After the sewage has passed, the valves close in succession,
and fitting closely into their seats, prevent the return of any foul or noxious air or
gas or effluvia.
For the purpose of purifying the pipe drains or sewers, connection at convenient
points is made between them and air or other blowing apparatus.-By these means,
a supply of air may be at any time forced into the pipes, drains, or sewers, or a
current of air may be maintained so long as may be desirable therein, it being
understood that the air thus supplied is directed into the pipes, drains, or sewers in
the direction of the flow of the sewerage towards the points of discharge, and
consequently in the direction in which the valves aforesaid are free to open.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed or carried out in
practice I hereby declare that what I claim is
The improved system for obviating the return of foul or noxious air and gases in
drain pipes and sewers, and for ventilating or purifying the atmosphere therein,
consisting in the combination in connection with the drain pipes and sewers of a
valve or valves, and air supplying channel, substantially as hereinbefore set forth
and described.
