PROVISIONAL SPECIFICATION.
Obviating and Preventing the Escape of Noxious Gases from
Sewers, Drains, Water Closets, and other like Places.
I, JOHN WARBURTON of Conisburgh via Rotherham in the County of York, Mining
Engineer and Certificated Colliery Manager do hereby declare the nature of this
invention to be as follows:-
This invention relates to, and consists of a System, by exhaustion, of ventilating,
Sewers, Drains, Water Closets and other places constructed for Sanitary purposes,
and also of an arrangement of Regulators at openings of Sewers, Drains &c., such
regulators being a necessary part of the system of ventilating by exhaustion.
The means to be employed for exhausting, are Furnaces and Fans (such as are
used in the ventilation of Mines) the foul gases to be passed through the Furnace or
a Fire previous to being ejected into the atmosphere.
The Furnaces, Fans &c. to be erected at suitable places and varying sizes to meet
the requirements of Cities, Towns and Villages.

I, JOHN WARBURTON of Conisburgh near Rotherham in the County of York,
Mining Engineer and Certificated Colliery Manager 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 and consists of a system, by exhaustion and induction,
of ventilating Sewers, Drains Water Closets and other like places constructed for
Sanitary purposes; by the adoption of an arrangement of Regulators at the openings
of Sewers, Drains and other like places where sewage matter, is admitted.
These regulators, which form the main feature in this invention, (and which render
a continuous air current in and through Sewers possible) consist of tube or pipe
shaped openings, into drains and sewers, having preferably, as a preventative against
a return current, diferentive areas, that is, the out side mouth of the opening has an
area larger than that of the inside.
The superior area being that exposed to the atmosphere and forming the mouth of
the air-inlet. The inferior area being that end of the tube shaped opening,
communicating with, and terminating in, the upper area of the drain or sewer at the
outflow or drain side of the trap, as shown in Sketch Section accompanying this.
These inlet regulators are of various sizes, and as few and as many may be put at
any inlet, as the drains Sewers, and centre outlet, may suggest.
The centre outlets, mean an arranged point or place connected with the sewers as
an only outlet for the sewer gases over a defined area.
All other means of
communication with the sewers, within each central area, being closed.
The communication with the atmosphere, being through the air-inlet regulators,
which admit from a minimum to a maximum according to requirements.
At the centres of outlet, circumstances of differing cases places, and positions, will
determine, if and whether it may or may not be advisible and needful to employ some
or any kind of inducement such as furnaces and other known means of inducing air
currents, by exhaustion. And where needful, by preference, a furnace or fire, through,
or over which, may be passed the outcoming gases.
The centre outlets selected, as to position, and other circumstances, with, or without
a shaft, stack, or chimney and fire; and all other, escapes-commonly called
ventilators closed, (or in new works not made) a current is set up and maintained,
through the inlet openings in direction of and to the centre outlet, carrying off and
diluting the sewer gases at the earliest moment, obviating and preventing, any
accumulation, or pressure taking place in the sewers or any escape of gases other than
at each centre outlet.
The extent of area to be ventilated to any one centre, will be guided, in existing
sewers by their capacity more than by distance.

page_text: The divisions, for the various centres do not affect the unity of any system of
Sewerage, as they are separated, for ventilating purposes, by automatic partitions,
where and when necessary.
The air inlets hereinbefore named, by preference, form a part of, and are combined
with Gullies and Traps being, in one, a ventilated-trapped Gully or Trap, and made
in and with, in one, the smallest cottage trap up to the largest street gully of all
shapes and capacities.
The regulated air inlets, may also be put to and connected with existing drains and
sewers for the purposes of ventilating them as herein before described, apart from the
use of the combined trapped and ventilated gully or trap.
The accompanying sketch section, shows the nature of this invention, which renders
possible a means and method of effectually ventilating drains and sewers, as herein
before described.
A A being trapped gully.
B. the outflow into drain or sewer.

D. the air-inlet opening.
The arrow showing the direction of the inlet air through the opening and into the
drain or sewer.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The adaptation of a method of causing a current of air to flow in and through
sewers and drains in a given direction, to a fixed outlet, for the purpose of ventilating
sewers and drains; substantially as herein described.
2. The air-inlet Gully trap, in one, as a ventilating trap, as herein described.
3. The method described herein of ventilating Sewers and Drains.
