PROVISIONAL SPECIFICATION.
Improvements in Syphon Cisterns for Flushing Water Closets and
other similar purposes.
CHARLES CHURCH, trading as Henry Conolly & Co. Sanitary Engineers
and Brass Founders, 42 Hampstead Road, and Tolmer Square, London, N.W.
do hereby declare the nature of this invention to be as follows:-
An arrangement of apparatus whereby water closets, urinals (or other similar
requirements) may be flushed at will with a certain quantity of water and its object
is to provide certain improvements in connection with the full and free discharge
of the water after the syphonic action has been set up.
It consists of a cast or wrought iron or steel tank of suitable size and shape
having in the centre of the bottom a rectangular or cylindrical well extending
downwards for a convenient distance therefrom the walls or sides of said well being
corrugated grooved or indented in any similar manner to allow of a free passage
for the water, this being an important part of my invention.
In the centre of the said well I provide the syphon leg or outlet pipe screwed
one end to receive a clamping nut to be fixed on underside of well to retain it in a
fixed vertical position and for connecting to union of discharge pipe.
In combination with the above I provide a heavy cast iron drum or plunger
of such a shape that it slides freely in the aforesaid well and over and enclosing
the said syphon leg tapering from its base to about half its height, near the top
I provide two lugs to receive the ends of a manipulating lever.
The action of the combination would be as follows:-
When the tank has been filled to a certain level with water the lever being
pulled downwards raises the drum or plunger which upon being released descends
somewhat suddenly by reason of its weight forcing the water upwards and over
the syphon leg thereby setting up a syphonic action by which the contents of the
cistern are discharged."

CHARLES CHURCH trading as Henry Conolly & Co. Sanitary Engineers
and Brass Founders 42 Hampstead Road N. W. and Tolmer Square N.W. 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:-
An arrangement of apparatus whereby water closets, urinals (or other similar
requirements) may be flushed at will with a certain quantity of water and its object
is to provide certain improvements in connection with the full and free discharge
of the water after the syphonic action has been set up.

page_text: In carrying my invention into practice I obtain a cast or wrought iron or steel
tank of suitable size and shape having in the centre of the bottom a rectangular
or cylindrical well extending downwards from the bottom of the aforesaid tank for
a convenient distance say four inches although I do not confine myself to the exact
depth or size-the walls or sides of the said well being corrugated grooved or
indented in any similar manner to allow of a free passage of water when the
plunger (hereinafter described) is brought into use this being an important part of
my invention.
In the centre of the said well I provide a syphon leg or outlet pipe screwed one
end to receive a clamping nut to be fixed on underside of well to retain it in a fixed
vertical position and for connecting to union of discharge pipe.
In combination with the above I provide a heavy cast iron drum or plunger with
square base tapering from its base to about one half its heighth and fitting into the
aforesido well leaving the corrugated walls free for the flow of water over the
syphon leg near the top of the said plunger I provide two lugs to receive the ends
of the manipulating lever.
On reference to the accompanying drawings A is the tank B is the well with
corrugated sides or walls as before described C is the cast iron drum or
plunger shewn by the dotted lines to be fitted into the well D is the manipulating
lever.
The action of the combination is as follows.
When the tank has been filled to a certain level with water the lever being
pulled downwards raises the drum or plunger which upon being released decends
somewhat suddenly by reason of its weight forcing the water upwards through the
corrugations over the syphon leg thereby setting up a syphonic action by which
the contents of the cisteru are discharged.
Having now particularly described and ascertained the nature of my inven-
tion & in what manner the same is performed 1 claim
1st. The rectangular or cylindrical well with walls corrugated grooved or
indented to allow of a fiee passage of the water under the said plunger and over the
syphon leg.
2nd. A combination of an apparatus for flushing water closets and other
analogous purposes by syphonic action substantially as specified.
Dated this 28th day of December 1896.
