, JOSEPH ARNOLD of 92, Woodchester Street, in the County of Middlesex,
Surveyor and Draughtsman, do hereby declare the nature of this invention to be as
follows:-
My Invention relates to improved apparatus for deodorizing and disinfecting sower
gases and matters; and it consists in an apparatus whereby soil or drain pipes are
relieved of gaseous pressure due to a sudden influx of water, and the gases in escaping
are caused to pass through or to come in contact in a more or less divided state, with a
disinfecting and deodorizing liquid, means being also provided for continuously
supplying such liquid to the soil pipe or drain.
The apparatus consists essentially of an inverted trumpet mouth, connected with the
soil pipe or drain and dipping just to or below the surface of the liquid contained in a
tank, so as only just to seal the trumpet mouth which has an external flange perforated
with small holes. The trumpet mouth is usually formed on an inverted U-shaped
pipe, and the sectional area of the pipe is preferably contracted at the bend in order to
give the gases the desired velocity on emerging from the trumpet mouth. The holes
in the flange around the trumpet mouth are filled with the disinfecting liquid either by
immersion or by capillarity, and the gases in escaping must pass either through the
holes therein or beneath the flange, and are thus brought into intimate contact with
the liquid and thereby deprived of all noxious germs and odor. The tank is supplied
with the liquid in regulated quantity from a tank above and is provided with an over-
flow discharging into the drain, in order to maintain the liquid level constant. At the
point at which the overflow is situated, a regulated quantity of another liquid is
supplied from another tank above, the two liquids being such that by their chemical
combination, gases will be generated having a powerful disinfecting and deodorizing
action on the sewer gases, the excess of liquid flowing into the soil pipe or drain, and
thereby keeping it sweet.

Sewer Gases.
I, JOSEPH ARNOLD, of 92, Woodchester Street, in the County of Middlesex,
Surveyor and Draughtsman, 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 improved ventilating, deodorizing, and disinfecting
apparatus, whereby soil or drain pipes are relieved of gaseous pressure due to a sudden
influx of water, and the gases in escaping are caused to pass through, or to come
in contact in a more or less divided state with, a disinfecting and deodorising
liquid, and whereby such liquid is continuously supplied to the soil pipe or drain
itself.
Reference is to be had to the accompanying drawing forming part of this
specification, which shows a vertical section of the apparatus.
The apparatus consists essentially of an inverted trumpet mouth dip pipe A applied
to a ventilating pipe B connected with the soil pipe or drain, said trumpet mouth
dipping just to, or below, the surface of a disinfecting liquid contained in a tank C so
as to be only just sealed thereby. The trumpet mouth A has a flange a parallel with
the liquid surface and perforated with small holes a¹ which become filled with the
disinfecting liquid either by immersion or by capillarity, and the gases, which in
escaping must pass either through the holes a¹ or entirely beneath the flange a, are
brought in a more or less divided state into prolonged and intimate contact with the
liquid in the tank C. The tank C is supplied with the liquid in regulated quantity
from a tank D above, and is provided with an overflow E discharging through the
ventilating pipe B into the drain, in order to maintain the liquid level in tank C
constant. The overflow pipe E leads out from the inside of the trumpet mouth to
prevent the direct escape of sewer gases without passing through the liquid, and it
terminates in a cup e within pipe B to which a regulated quantity of another liquid is
supplied from a second tank F, the two liquids being such that by their chemical
. combination gases will be generated having a powerful disinfecting and deodorizing
action on the sewer gases. as they ascend through pipe B and before reaching the
trumpet mouth. The excess of liquid flows into the soil pipe or drain, and helps to
keep it sweet.
.
The liquid supplied to tank C from tank D through a drip tap d is preferably a
solution of manganate of soda whilst that supplied from tank F may be dilute
sulphuric acid. The latter is also supplied from a drip tap fand falls into a funnel
pipe G which is trapped, to prevent the escape of sewer gas, by its lower end which.
is closed and has upwardly inclined lateral apertures, dipping into the overflow
cup e.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The herein described apparatus to be applied to the ventilating pipes of soil or
drain pipes, consisting of a trumpet mouth or dip pipe having a perforated flange
lightly sealed by immersion in a disinfecting liquid, substantially as and for the
purposes specified.
2. The herein described apparatus to be applied to the ventilating pipes of soil or
drain pipes, consisting of a trumpet mouth or dip pipe having a perforated flange
lightly sealed by immersion in a disinfecting liquid, and having an overflow termi-
nating in a cup within the ventilating pipe, in combination with means of supplying
the liquid to the tank in which the dip pipe is immersed, and a second liquid to the
cup in which the overflow pipe terminates, as and for the purpose specified.
