PROVISIONAL SPECIFICATION.
Improvements in Syphon Water Waste Preventers.
JOHN DAVEY Queen Street, Hitchin, Herts, Engineer do hereby declare the nature
of this invention to be as follows:-
This invention is applicable to syphon cisterns for water closets.
In my improved syphon I prefer to use what is known as a bell syphon with a plate
or piston fixed on the bottom part of same. The said plate or piston is used to charge
the syphon with water. The plate or piston is made of malleable or other metal
flanged round the outside and the flat surfaces corrugated or indented to stiffen them.
On the upper part of the bell syphon or a fixed syphon and above the water line I use
a valve that is open when the syphon is in its normal position, but when the syphon
is being charged with water to start it working, the aforesaid valve first lets out the
air, secondly it closes before the syphon starts to work, thirdly as soon as the charge
has gone the valve opens and admits air into the syphon.
In the accompanying drawing Fig. 1 is a plan, Figs. 2 and 3 are practically similar
sections illustrative of its operation.
Fig. 2 A is the cistern, B is the syphon delivery pipe, C is the movable bell for
starting syphon, D is a flanged and corrugated or indented plate attached to the

Improvements in Syphon Water waste Preventers.
JOHN DAVEY Engineer Queen Street Hitchin Hertfordshire. I 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:-
In my improved syphon I prefer to use what is known as a bell syphon with
a plate or piston fixed on the bottom part of same, the said plate or piston is used
to charge the syphon with water.
The plate or piston is of malleable or other metal flanged around the outside and the
flat surfaces are corrugated or indented to stiffen them. On the upper part of the bell
syphon or a fixed syphon and above the water line I use a valve that is open when the
syphon is in its normal position but when the syphon is being charged with water to
start it working the aforesaid valve first lets out the air, secondly it closes before
the syphon starts to work, thirdly as soon as the charge has gone the valve opens
and admits air into the syphon.

page_text: In the drawings sent with the Provisional Specification Fig. 1. is a plan Fig. 2 and
are practicaly similar section illustrative of its operation.
Fig. 2. A is the cistern B is the syphon delivery pipe. C is the movable bell for
starting syphon, D is a flanged and corrugated or indented plate attached to the
bell fitting loosely into the cistern. Fig. 1. D1. D 2. D 3. D 4. D 5. D 6. show
corrugations or indentations for stiffening the same. E Fig. 1. is a lever for starting
syphon to work. El spindle. F Farms connected to bell syphon. G Fig. 2. counter-
balance weight to bring bell syphon and plate into its normal position. H air valve.
I lever for working same.
When it is desired that water should flow from the cistern A. the lever E Fig. 1.
secured on the spindle E 1. and through the arms F. F is drawn down and the bell (
and corrugated plate D 1. D2. D 3. D 4. D 5. D6 will be depressed this will put a
pressure on the water then below the corrugated plate and force it up into pipe B.
which will start the syphon to work.
The use and action of the valve H is as follows as soon as the water is forced up
into the bell C. the air escape. The drawings show the valve & bell syphon in its
normal position. The lever I is in contact with the spindle E 1. which opens the
valve. When the lever E and arms F F are depressed the lever I is liberated and the
valve H by its own weight or the vacuum closes the top of the syphon, after the charge
of water is gone out of cistern the counterbalance weight G brings the bell syphon
into its normal position which opens the valve and admits air into the syphon.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is as follows.
1st. In combination with a bell syphon a malleable metal flanged, corrugated or
indented plate, fixed to the bell and loosely fitting the cistern as herein described and
illustrated in the accompanying drawing.
2nd. The combination of a valve H. working on a syphon above the water level,
with the lever I. for working the same substantially as and for the purpose described
and illustrated in the accompanying drawings.
