PROVISIONAL SPECIFICATION.
Improvements in Flushing Apparatus for Water-closets.
Water
We, JOHN RING, Plumber, of Kingstown, and JAMES KELLY of Blackrock,
Inspector, both in the County Dublin ireland, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to produce apparatus for the purpose of controlling,
or adjusting the supply of water in the operation of flushing closets, and for such like
purposes.
In carrying out our said invention we arrange in the ordinary cistern, or tank a
suitable vessel which for convenience we call a "container."
This container is provided with an air inlet on its upper surface and communicates
with the ordinary syphon tube (near its free end) by means of a horizontal pipe fitted
with a stop cock for adjusting the supply.
The container also communicates with the top of the syphon tube by an exhaust
pipe of suitable bore, for the purpose presently described.
The action of the apparatus is briefly as follows.
The cistern or tank being filled in the ordinary manner, water will rise through the
open or free end of the syphon, thence through the horizontal pipe (the stop cock
being adjusted for that purpose) and fill the container.
Now when the cistern valve is raised in the usual way the syphon becomes charged,
and water will continue to flow until the container is exhausted when the ingress
of air from container through exhaust pipe to the syphon untraps the latter,
and arrests the current of water, thus preventing the unnecessary use, or waste
of water.
When it is desired to renew the flush the cistern valve is again raised and the above
automatic action is repeated.

COMPLETE SPECIFICATION.
Improvements in Flushing Apparatus for Water-closets.
We, JOHN RING, Plumber, of Kingstown, and JAMES KELLY of Blackrock, Water
Inspector, both in the County Dublin, Ireland, 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 produce apparatus for the purpose of controlling or
adjusting the supply of water in the operation of Alushing closets, and for such like
purposes.
In carrying out our said invention, we arrange in the ordinary cistern or tank a
suitable vessel which for convenience we call a "container."
This container is provided with an air inlet on its upper surface, and communicates
with the ordinary syphon tube (near its free end) by ineans of a horizontal pipe fitted
with a stop cock for adjusting the supply.
The container also communicates with the top or bend of the syphon tube by an
exhaust pipe of suitable bore for the purpose presently described.
In order that our said invention may be more readily understood we will describe
the accompanying drawings.
A represents an ordinary cistern or tank,

page_text: c the air pipe,
d the horizontal communicating pipe fitted with an ordinary tap as shown,
e the exhaust pipe from the container to the ordinary syphon f; it will be noted
that this pipe joins the syphon at the top or bend;
9 is the flushing pipe closed by a valve and is operated in the usual way by chain
and lever as shown.
The action of the apparatus is briefly as follows.
As the cistern or tank is being filled in the ordinary manner, the water will rise
through the open or free end of the syphon, thence through the horizontal pipe d; (the
stop cock being adjusted for that purpose) and fill the container.
Now when the valve his raised, water in rushing from the cistern through the
flushing pipe 9, will produce a vacuum in the uncharged portion of the syphon,
causing the water to flow through same until the container is exhausted, when the
ingress of air through the pipe C, and the container, passing round the exhaust e will
untrap the syphon, and arrest the current, thereby preventing the unnecessary use, or
waste of water.
Of course it is understood that the valve his not kept open during the action
of the apparatus, otherwise the whole contents of the cistern may flow through same.
To obtain a proper flush it is therefore only necessary to open the valve momentarily,
and each time it is raised, the same automatic action is repeated.
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.
For the purpose of flushing water closets, the use and application of apparatus,
constructed, arranged, and operating in the manner substantially as herein specified
and set forth.
