Road Battersea in the said County of London Commercial Clerk the members of
The Iron Ring Inventors' Syndicate of 20 Oakley Crescent aforesaid do hereby
declare the nature of this invention to be as follows:-
The object of our invention is to :-automatically supply a small quantity of
disinfectant liquid to the water used for flushing water closets, urinals, and the like
on each occasion that they are flushed.
This is accomplished by providing a containing vessel (hereinafter called the
"container") constructed as hereinafter described either wholly or partially filled
with liquid disinfectant, and attaching the same to the cistern as hereinafter
described.
The container is fitted with an air-tight stopper as shewn by the annexed drawing
(A) through which passes a tube (B) constructed as hereinafter described, which
extends inside the container to within a small distance (C) from the opposite end of
the container to that in which the stopper (A) is fixed and the tube extends in the
opposite direction from the stopper to within a regulated distance above the surface of
the water in the cistern when at its lowest (D). A short tube (E) with a small bore
also passes through the stopper and a moveable stopper (F) is also provided at the
opposite end of the container.
I
To fill the container with disinfectant the stopper (F) is removed and the short
tube (E) is plugged or stopped with the finger or otherwise and the liquid poured in
until it reaches near to the end of the tube inside the container (C). The stopper (F)
is then replaced so as to admit of no air passing through it.
The tube (B) consists of two parts one being fixed in the stopper (A) and the other
fitted round the fixed part so as to slide up and down it to regulate the distance
between the end of the tube (D) and the surface of the water in the cistern when
at its lowest

page_text: The apparatus is attached to the cistern and lodged or fixed in such a position so
that the end of the tube (D) is left a small distance above the surface of the water in
the cistern when it is at its lowest, and the plug is then removed from the
small tube.
When the water has risen above the end of the tube (D) no air can enter the
container and consequently no disinfectant can escape, but when a flush takes place
the water in the cistern falls below the end of the tube (D) and allows a small
quantity of air to pass up the tube (B) into the container until the water in the cistern
has risen again to the end of the tube (D). During the time the air is entering the
container the disinfectant escapes through the small bore in the tube (E) and falls into
the water in the cistern.
Thus by means of this apparatus, the water standing in or running through the
cistern, and the pan of the closet, urinals, and the like is always mixed with
disinfectant fluid; the water in the cistern not being able to enter the container, the
water in the cistern and pan is always disinfected to a uniform degree, and the
displacement of water in the cistern caused by the tube (B) is so small as to make no
appreciable difference in the force of the flush.
We do not limit ourselves to a container of any particular shape nor to the
arrangement of the tube (B and E) passing through a stopper as the tubes and
container might be made in one or more piece or pieces.

Crescent Chelsea in the County of London Solicitors' Clerk SYDNEY HARRY Moss
of 129 Keppel Street Chelsea aforesaid Coach Builder ERNEST JOHN Moss of

Street Chelsea aforesaid Electrician and CHARLES THOMAS CLARK of 159* Church
Road Battersea in the said County of London Commercial Clerk the members of
The Iron Ring Inventors' Syndicate of 20 Oakley Crescent aforesaid 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:-
The object of our invention is to automatically supply a determinable quantity of
disinfectant fluid or liquid to the water used for flushing water-closets urinals and the

page_text: like on each occasion they are flushed. This is accomplished by providing a
containing vessel (hereinafter called the "container") constructed as hereinafter
described partially filled with disinfectant the remaining space containing air and
attaching the same to the cistern as hereinafter described and in which cistern the
level of the water rises and falls each time the closet urinal or the like is flushed.
The action of the apparatus depends as hereinafter set forth upon variations in the
volume and pressure of air in the container consequent upon variations in the level of
the water in the cistern.
The container (a) (as shown by Fig. 1 of the annexed drawings) is fitted with an
airtight stopper (b) through which passes a tube (c) (constructed as hereinafter
described) which extends inside the container to within a small distance (d) from the
opposite end of the container to that in which the stopper () is fixed and the tube.
extends in the opposite direction from the said stopper to within a regulated distance.
above the surface of the water in the cistern when it has fallen to its lowest level (e),.
a short tube (f) with a small bore also passes through the said stopper (b) and a
moveable airtight stopper (g) is also provided at the opposite end of the container
from that in which the stopper (b) is fixed.
The tube (c) consists of two parts, one being fixed in the stopper (b) and the other
fitted round the outside or inside of the fixed part of the tube so as to slide up and
down it, to regulate the distance between the end of the tube (e) and the surface of
the water in the cistern when at its lowest level, Fig. I shews the second part of the
tube () fitted inside the fixed part.
To put the lisinfectant liquid into the container the stopper (g) is removed and the
short tube (f) is plugged or stopped with the finger or otherwise and the liquid
poured in until it reaches near to the end of the tube inside the container (d) the
stopper (g) is then replaced so as to admit of no air passing through or round it."
The apparatus is attached to the cistern and lodged or fixed in such a position so
that the end of the tube (e) is left a small distance above the surface of the water in
the cistern when it is at its lowest as shewn in Fig. II and the plug is then removed
from the small tube.
When the apparatus is lodged or fixed as stated above and the level of the water
has risen to its highest as shewn in Fig. I the supply of air up the tube (c) will be cut
off and the imprisoned air in the space H will become compressed and prevent the
disinfectant fluid from escaping through the small tube F but when the level of the
water falls below the end of the tube (e) as shewn in Fig. II air will pass up
the tube (c) causing the air in the space H to expand and force a small quantity of
the disinfectant liquid through the small bore in the tube (f) and the liquid will fall
into the water in the cistern until equilibrium is restored by the level of the water in
the cistern rising.
When the water level rises the action will be reversed by cutting off the supply of
air up the tube (c) after which the disinfectant fluid will still escape from the short
tube (f) until equilibrium is again restored by the air in the space H becoming
compressed.
It will be noted that during the time the water is allowed to fall below the end of
the tube (e) the disinfectant fluid will escape until the container is empty.
The end of the tube (e) is made bell-shaped so as to prevent any water remaining
in the said tube which might happen if the tube was of an equal bore and the surface.
of the water while falling remained smooth.
Thus, by means of this apparatus which requires practically no skill in filling, the.
water standing in or running through the cistern and the pan of the closets, urinals
and the like is always mixed with disinfectant fluid; the water in the cistern not being
able to enter the container the disinfectant fluid does not get diluted; the apparatus
can be regulated so as to allow either a large or small quantity of disinfectant liquid
to fall into the water in the cistern, and the displacement of the water in the cistern
caused by the tube (c) is so small as to make no appreciable difference in the force of
the flush.
We do not limit ourselves to a container of any particular shape or material nor to.

page_text: the arrangement of the tubes (c & f) passing through a stopper as the tubes and
container might be made in one or more piece or pieces and the small tube might be
replaced by a small hole in the container.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. In apparatus for automatically supplying disinfectant liquids to water closets
urinals and the like, the use of a vessel containing disinfectant liquid and imprisoned
air attached to a cistern through which the flushing water passes such vessel being
fitted with an air tight stopper closing an aperture through which the disinfectant
fluid is poured into such vessel, a small bore tube through which the disinfectant
liquid is expelled and a larger bore tube through which air is admitted by reason of
variations in the volume and pressure of the air in the vessel consequent upon
variation in the level of the said water substantially as described.
2. The use in connection with a containing vessel in such apparatus of tubes (such
as c&f) substantially as and for the purpose described and illustrated.
3. The improved apparatus for automatically supplying disinfectant liquids to water
closets urinals and the like substantially as described and illustrated in Figs. I & II.
