Complete Specification Left, 5th Nov., 1889-Accepted, 7th Dec., 1889
PROVISIONAL SPECIFICATION.
Improvements in the Ventilation and Flushing of Sewers and
Apparatus for that Purpose.
I, GEORGE AMBROSE WALLIS of 14 Seaside Road, Eastbourne in the County of
Sussex Civil Engineer, Member of Institution Civil Engineers, London do hereby
declare the nature of this invention to be as follows:-
My invention relates to means of ventilating and flushing sewers, applicable in
localities where water under pressure is available.
I provide a tower or shaft in which, or in connection with which, I arrange a
turbine or other engine worked by water under pressure, and a fan or other
ventilator worked by it. The tower or shaft being in communication with a sewer
or set of sowers, the noxious gases are withdrawn therefrom by the action of the
ventilator and are discharged at the summit of the shaft or tower, while fresh air
is drawn into the sewer by gratings or other openings. The water, after working
the turbine or other engine, is discharged into a tank provided with a siphon.
From time to time, as the tank becomes filled sufficiently to charge the siphon,
the contents of the tank are discharged into the sewer flushing it.
Dated this 23rd day of March 1889.

Improvements in the Ventilation and Flushing of Sewers and
Apparatus for that Purpose.
I, GEORGE AMBROSE WALLIS of 14 Seaside Road, Eastbourne in the County of
Sussex, Civil Engineer, Member of Institution of Civil Engineers London, 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 means of ventilating and flushing sewers, applicable in
localities where water under pressure is available.
I provide a tower or shaft in which, or in connection with which, I arrange a
turbine or other engine worked by water under pressure and a fan or other
ventilator worked by it. The tower or shaft being in communication with a sewer
or set of sewers, the noxious gases are withdrawn therefrom by the action of the fan
or ventilator and are discharged at the summit of the shaft or tower, while fresh air
is drawn into the sewer by gratings or other openings. The water, after working the
turbine or other engine, is discharged into a tank provided with a siphon. From
time to time, as the tank becomes filled sufficiently to charge the siphon, the contents
of the tank are discharged into the sewer or set of sewers for flushing.
The accompanying drawing is a section representing a set of sewers with means of
ventilating and flushing, according to my invention, applied to thein. A A represent
air pipes and their bianches leading from the highest parts of the sewers S to the base
of a ventilating shaft Y. In this shaft is a turbine T driving a suction fan F by
which the air and gases from the sewers are drawn into the shaft to be discharged at
the top, which may be carried to a considerable height above the ground. The water,
after driving the turbine T may pass into tank R provided with a siphon P, so that
from time to time the contents of the tank are discharged into the sewers for the
purpose of flushing. them.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
For the ventilating and flushing of sewers, the combination of a turbine and fan or
their equivalents in a ventilating shaft, air pipes and branches from the sewers to the
shaft, and an intermittent siphon flushing tank, substantially as described.
