I, PATRICK O'Dowd, of Falduff Lodge, Westport, Ireland, Landed Proprietor
and Farmer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved apparatus for disinfecting sewer gas in
water closets, so constructed and arranged that it may be readily applied to any
ordinary existing water closet or to pans of the old form, and its object is to ensure
that no gas shall pass from the house-drain or sewer through the closet, without
being disinfected by passing also through a disinfecting agent or composition
contained within the apparatus, before escaping into, or intermixing with the
surrounding air.
In applying my invention to an ordinary water closet, I propose to arrange
on each side of the closet-pan and below the seat, a chamber for receiving the
disinfecting substance, and at the top of each chamber I provide a ventilator
of wire, iron, or other suitable material, in the closet-seat. The lid of the
closet is furnished on its underside with a chamber of circular or other suitable
form and dimensions to fit within the top of the pan and the opening formed
in the seat, a valve or ventilator being constructed in or about the centre of
the lid. In this latter chamber as well as in the two side chambers, a sufficient
quantity of peat charcoal or other disinfecting agent or composition is introduced,
and the underside of the chamber on the lid being formed of wire or perforated
metal, the foul air or gas rising in the pan, will pass through the composition
and become disinfected thereby before escaping into the surrounding air. In
the upper part of the pan are provided lateral orifices or air valves, furnished
on their inner sides with suitable wire caps or ventilators, through which gas
may pass to the side chambers where it will become disinfected by percolating
through the composition contained therein before escaping through the ventilators
arranged in the seat as already mentioned.
Or I may dispense with the side chambers and their ventila tors in applying my
invention to a pan of the old form without lateral air openings, in which case a
disinfecting chamber will be provided only upon the lid of the closet and furnished
with upper and lower ventilators.
In either case a closure is ensured around the chamber on the lid by the use of
either a circular band of rubber or other suitable material arranged to fit around
the said chamber, or strips of rubber or like material arranged on the underside
and near the edges of the closet-seat.
By the above described construction of apparatus it will be evident that all foul
air or sewer gas passing out from the closet must of necessity percolate through
the disinfecting chamber or chambers and the composition or material contained
therein, by which means it will be disinfected and rendered harmless.

I, PATRICK O'Dowd of Falduff Lodge, Westport, Ireland, Landed Proprietor
and Farmer, 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 an improved apparatus for disinfecting sewer gas in
water-closets, so constructed and arranged that it may be readily applied to any
ordinary existing water-closet or to pans of the old form, and its object is to ensure
that no gas shall pass from the house-drain or sewer through the closet, without
being disinfected by passing also through a disinfecting agent or composition
contained within the apparatus, before escaping into, or intermixing with the
surrounding air.
On the accompanying drawings illustrating my invention,
Figure 1 is a vertical section of my improved water-closet disinfecting
apparatus ;
Figure 2 being a sectional plan of the same seen from above.
In applying my invention to an ordinary water-closet as shewn on the drawings,
I arrange on each side of the closet-pan A and below the seat, a chamber D
for receiving a suitable disinfecting substance, and at the top of each chamber D,
1 provide a ventilator a of wire, iron or other suitable material, in the closet-
seat B. The lid C of the closet is furnished on its underside with a chamber E
of circular or other suitable form and dimensions to fit within the top of the
pan A and the opening formed in the seat, a valve or ventilator a' being
constructed in or about the centre of the lid C. In this latter chamber, E, as
well as in the two side chambers D, a sufficient quantity of peat-charcoal or
other disinfecting agent or composition is introduced, and the underside of the
chamber E being formed of wire or perforated metal, the foul air or gas rising
in the pan, will pass through the composition and become disinfected thereby
before escaping into the surrounding air.
In the upper part of the pan A are provided lateral orifices or air-valves b,
furnished on their inner sides with suitable wire caps or ventilators b', through
which gas may pass to the side chambers B where it will become disinfected by
percolating through the composition contained therein before escaping through the
ventilators a, a arranged in the seat B as already mentioned.
Or I may dispense with the side chambers and their ventilators in applying my
invention to a pan of the old form without lateral air openings, in which case a
disinfecting chamber will be provided only upon the lid of the closet and furnished
with upper and lower ventilators.
In either case a closure is ensured around the chamber E on the lid by the use
of either a circular band F of rubber or other suitable material arranged to fit
around the chamber E, as shewn, or strips of rubber or like material arranged on
the underside and near the edges of the closet-seat, B.
By the above described construction of apparatus, it will be evident that all
foul air or sewer gas passing out from the closet must of necessity percolate through
the disinfecting chamber or chambers and the composition or substance contained
therein, by which means it will be disinfected and rendered harmless.
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
claim is:-
1. A disinfecting apparatus for water-closets consisting of a chamber E formed

page_text: on or in the lid of the closet, and having a ventilator a¹ in its upper and underside,
in combination with or without lateral chambers D arranged at the sides of the
pan A, having ventilators a formed in the closet seat B, said chambers D and E
being arranged to contain a disinfecting composition, for the purposes and as
described with reference to the accompanying drawings.
