of this invention to be as follows:-
The object of our invention is to automatically supply a small quantity of disin-
fectant 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") as shewn by the annexed drawing (A) in which is inserted a syphon (B)
constructed as hereinafter described. The container is provided with an apperture (C)
through which the disinfectant liquid is poured to fill the container. The
apperture (C) may be closed with a perforated stopper to keep out dust, but so as to
allow a free passage of air.
The end of the syphon outside the container is provided with a valve which is
automatically closed when submerged in water.
The apparatus when filled is tilted sideways so as to fill the syphon with disinfectant
and placed so that the end of the syphon at which the valve is fitted is left a regulated
distance above the surface of the water in the cistern when at its lowest.
When a flush takes place, the water in the cistern falls below the end of the syphon
at which the valve is fitted and the valve consequently opens and allows the disinfectant
fluid to escape until the water rises sufficiently to close the valve.
When the surface of the disinfectant in the container is lower than the surface of
the water in the cistern the valve, prevents the dilution of the former.
The end of the syphon inside the container extending lower than the end outside,
prevents the syphon emptying itself when once filled.
Thus by means of this apparatus the water standing in or running through the
cistern and the pan of the closets urinals and the like is always mixed with disin-
fectant fluid and the displacement of water in the cistern caused by the end of the

page_text: syphon and valve is so small as to make no appreciable difference in the force of
the flush.
We do not bind ourselves to a container of any particular shape nor to a valve of
any particular construction or to the container and syphon being made in any number
of pieces.

Electrician and CHARLES THOMAS CLARK of 1594 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 inven-
tion 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 liquid to the water used for flushing water closets urinals and the like
on each occasion they are flushed.
This is accomplished (as shewn in the annexed drawings) by providing a containing
vessel (a) (hereinafter called the "container") in which is inserted a syphon (b)
(constructed as hereinafter described). The container is provided with an apperture (c)
through which the disinfectant liquid is poured to fill the container. The said
apperture may be partially closed with a perforated stopper to keep out dust but so as
'to allow a free passage of air. The end of the syphon outside the container
terminates with a small bore and is opened and closed by means of a valve (d)
capable of being automatically closed when submerged in water as shewn in Fig. I.
The syphon is inserted in the container so as to allow the surface of the disinfectant
liquid in the container when filled to rise higher than the top of the syphon by which
means the latter becomes charged with the disinfectant liquid which will then flow
from the end of the syphon outside the container.
When the container and syphon have been thus filled the end of the syphon outside
the container must be closed so as to prevent the disinfectant liquid escaping until the
apparatus is attached to the cistern.

page_text: The apparatus when filled is hung on the side of the cistern by the syphon or
otherwise lodged or fixed in such a position so that the end of the syphon at which
the valve is fitted is left a regulated distance above the surface of the water in the
cistern when at its lowest level.
When a flush takes place the water in the cistern will fall below the valve which
consequently drops and the small bore of the syphon being then open allows the
disinfectant fluid to escape and fall into the water in the cistern (as shown in Fig. II)
until the water rises sufficiently high to close the valve.
It will be noted that the action of the apparatus depends upon the rise and fall of
the water in the cistern and while the level of such water is below the valve the
disinfectant liquid will continue to flow until the water rises or the syphon stops
working as hereinafter explained.
When the surface of the disinfectant liquid in the container has fallen below the
surface of the water in the cistern the valve prevents the water entering the syphon
and makes it impossible for the disinfectant liquid to get diluted.
The end of the syphon inside the container is so constructed as to extend lower than
the end outside which will prevent the syphon from working when the surface of the
said liquid in the container has fallen level with the end of the syphon outside the
container consequently the latter will not empty itself when once filled.
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 displacement of water in the
cistern caused by the end of the syphon and valve is so small as to make
no appreciable difference in the force of the flush; and the apparatus is capable of
being attached to a cistern which is fixed near to a ceiling or other obstacle above the
cistern.
We do not bind ourselves to a container of any particular shape or material, nor
to a valve of any particular construction, or to the container and syphon being made
in any particular number of pieces.
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
apperture through which the disinfectant liquid is poured into the vessel; a syphon
through which such disinfectant liquid is allowed to flow by means of a valve
consequent upon the rise and fall of the said water in the cistern substantially as
described.
2. The use in connection with such apparatus of a syphon and valve 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.
