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 tank or containing vessel as shewn in the
annexed drawing (A) (hereinafter called the container) provided with a small
outlet (B), an inlet for air (C) and an airtight stopper (D).
The container is filled through the aperture in which the stopper (D) is fitted, until
the disinfectant fluid reaches near to the top of the inlet (C).
The outlet and inlet (B & C) are opened and closed by means of pads fitted on a
lever suspended underneath the container (E).
The pads are kept pressed against the outlet and inlet by means of a weight (F)
suspended from the opposite end of the lever to that on which the pads are fitted.
The outlet and inlet are opened by means of a receptacle suspended from the
lever (G).
This receptacle has a hole in the bottom (H) and when the receptacle is empty it is
lighter than the weight (F).
The apparatus is placed above the cistern in such a position so as to allow the
receptacle (G) to be submerged beneath the surface of the water in the cistern when
it has risen to its highest.
When a flush takes place, the water in the cistern falls quicker than that in the
receptacle (G) so that the weight of the latter, with the water momentarily left or
held in it is sufficient to counter-balance the weight (F) and so opens the outlet and
inlet (B&C) at the same time.

page_text: The inlet (C) now being open allows an inlet of air, and a consequent escape of
disinfectant through the outlet (B).
While the water in the cistern is below the receptacle (G), the water held by the
latter gradually escapes through the hole (H); thus the balance is again reversed,
and the outlet and inlet (B & C) closed.
Thus, by means of this apparatus, the container being kept airtight, the disinfectant
fluid does not evaporate or deteriorate; the water standing in or running through the
cistern and pan of the closets, urinals and the like is always disinfected; and there is
no displacement of water in the cistern, by reason of the receptacle (G) being
submerged, sufficient to make any 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 lever being worked by a suspended weight as the end of the
lever on which the weight is suspended might be made heavier in itself, or be worked
by a spring.

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 fixed quantity of
disinfectant fluid or liquid to the water used for flushing water-closets urinals and
the like on each occasion they are flushed.
This is accomplished by providing a tank or containing vessel (a) (hereinafter
called the "container") provided with a small opening or outlet (b) an aperture (c)
a perforated stopper (d) (which will freely admit air but prevent dust entering the
container) a lever or rod (e) a weight (f) a receptacle (g) (constructed as hereinafter
described) and a pad () and attaching the same to the cistern as hereinafter described

page_text: and in which cistern the level of the water rises and falls each time the closet urinal
and the like is flushed and the action of the apparatus depends upon such rise and fall
as hereinafter described.
To fill the container with disinfectant liquid the stopper (d) is removed and the
liquid poured through the aperture (c).
The outlet (b) is closed and opened by coming in contact with and being released
from the pad (h) fitted on the lever (e) suspended underneath the container. The pad
is brought in contact with and kept pressed against the outlet (b) by means of a
weight (f) suspended from the opposite end of the lever to that on which the pad
is fitted.
The outlet is released from the pad and opened by means of the receptacle (g)
suspended from the lever as shewn in Fig. I.
This receptacle is made buoyant by means of an air tight chamber fitted round it
and has a hole in the bottom (i) and when the receptacle is empty it is lighter than
the weight (f).
The receptacle is attached to the lever by means of an arm which can be moved
along the lever to enable the same to be accurately adjusted and is wedged or fixed
with a pin, the weight can also be moved along the lever and is fixed in like manner.
We find that the apparatus works best without the inlet for air as shewn by our
Provisional Specification and drawing it being impossible to effectually close the inlet
and outlet by means of two pads on the one lever so we prefer to admit air to the
container by perforating the stopper as shewn in our Complete Specification and
drawings.
The apparatus is placed above the cistern in such a position so as to allow the
receptacle (g) to be submerged beneath the surface of the water in the cistern when it
has risen to its highest level as shewn in Fig. I.
When a flush takes place the level of the water in the cistern falls below the
receptacle (9) leaving the latter partly filled with the water (as shewn in Fig. 11) and
the weight of the receptacle with the water momentarily held in it is sufficient to
counterbalance the weight (f) and weigh down the end of the lever on which the pad
is fitted, the outlet (b) is thus opened and the disinfectant fluid will flow and fall into
the water in the cistern.
While the water is below the receptacle the water held by it gradually escapes
through the hole in the bottom; thus when the receptacle has emptied itself it is
raised by the weight (f) which brings the pad again in contact with the outlet (b) and
so closes it as shewn in Fig. III.
Thus by means of this apparatus which requires practically no skill in filling the
water running through the cistern and pan of the closets, urinals and the like is
disinfected to a uniform degree; the disinfectant liquid does not get diluted by the
water; there is no displacement of water in the cistern by reason of the receptacle
being submerged sufficient to make any appreciable difference in the force of the flush,
and in case the water should fail to enter the cistern the container will not allow the
disinfectant fluid to run to waste.
We do not limit ourselves to a container of any particular shape or material or to
the arrangement of the lever being worked by a weight as the end of the lever on
which the weight is suspended might be made heavier or be worked by a spring
neither do we limit ourselves to the receptacle being made buoyant by means of an air
tight chamber as the same might be accomplished by means of cork or other buoyant
material attached to the receptacle.
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 attached to a cistern through which the flushing
water passes such vessel being fitted with a perforated stopper placed in an aperture
through which the disinfectant liquid is poured to fill the vessel; an aperture through

page_text: "which the said disinfectant liquid is allowed to escape by means of a lever worked by
a weight and receptacle consequent upon the rise and fall of the said water in the
-cistern substantially as described.
2. The use in connection with a containing vessel in such apparatus of a lever,
weight and receptacle such as E F and G 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 and III.
