WILLIAM CHARLES BALDWIN, Heeley Road, Selby Oak, Birmingham, Plumbers
Brass Finisher, do hereby declare the nature of this invention to be as follows:-
A perfect water waste preventing syphon cistern for flushing closets and urinals
having a lock ball valve by an excentric cam on the leaver so as to prevent any water
runing in while the said leaver is pulled for discharge or mischeif or tied down in closit
the syphon is charged by an ariumatic action of the valve on top of discharge pipe
which replaces itself as soon as the syphon is charged if the leaver be held or not thus
insuring a full discharge of the whole contence of the cistern the force increesing
towards the end of the flush.
I propose to fit
cistern with a ball valve of ordinary size according to the
my
requirments of the cistern which ball valve shall be comprised of a valve in the form
of a plug working horizontaly in the barril of ball valve which ball valve shall be
closed in the ordinary maner when cistern is full by means of a leaver and copper ball
fitted in plug the plug shall be fitted with a small friction wheel working in a slot
made in the outward end of plug which friction wheel shall be fitted so as to project
about one third out of end of plug.
My cistern shall be fitted with a leaver working across the narrow way of the
cistern on the said leaver I shall fit an excintric cam which will come in close con-
junction with friction wheel which said wheel will rest under the indentation on
excintric when cistern is not in action when leaver is pulled down for flush or discharge
excrintric cam presses against friction wheel in plug closes the ball valve thus
preventing any water runing into cistern while leaver is held or fastned down in
closit.
The syphon is started by means of a valve fitted on top of syphon pipe which said
valve when cistern is filled to its proper height is one inch under water the pulling
down of leaver coming in contact with valve by means of a fork attached to the leaver
which said fork opens valve and starts the syphon which fork after bearing open the
valve automatically removes itself allowing the valve to close instantaniously thereby
constituting it a syphon cistern.

page_text: I, WILLIAM CHARLES BALDWIN of Heeley Road Selby Oak Birmingham Plumbers
Brass Founder 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:—
I make a perfect water waste preventing syphon cistern for flushing closets and
urinals having a lock ball valve with an eccentric cam on the lever in order to prevent
any water running into cistern while the said lever is pulled for discharge or otherwise
tied down.
The syphon is charged by an automatic action of the valve on top of discharge pipe
which replaces itself as soon as the syphon is charged whether the lever be held down 1
or not thus insuring a full discharge of the whole contents of the cistern.
1 fit my cistern with a ball valve (A) of ordinary size according to the requirements
of the cistern.
The said ball valve (A) is made in the form of a plug (B) working horizontally in
the barrel of said valve which is closed in the ordinary manner when cistern is full
by means of a lever (C) and copper ball (D) the lever being fitted into said plug (B).
The said plug (B) is fitted with a small friction wheel (E) working in a slot made
in the outward end of plug (B) which friction wheel (E) is made to project about one
third out of end of plug (B).
I also fit my cistern with a lever (F) working across the narrow way of the cistern.
On the said lever (F) there is an eccentric cam (G) which comes in contact with
above named friction wheel (E) the said wheel resting under the indentation on said
eccentric cam (G) when the cistern is not in action.
When the said lever (F) is pulled down for the discharge of water the eccentric
cam (G) presses against the friction wheel (E) in plug (B) which closes ball valve (A)
thus preventing any water running into cistern while lever (F) is held or fastened
down.
In order to start the action of the syphon I fit on top of syphon pipe (H) a valve (I)
which is one or more inches under water when the cistern is filled with water to its
proper height.
To the said lever (F) I attach a fork (K) and by pulling down the said lever (F)
the said fork (K) opens valve (I) and sets into action the sunbon (H\

page_text: The said fork (K) after bearing open the said valve (I) automatically removes
itself allowing the said valve (I) to close immediately thereby constituting it a syphon
cistern.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
1. The eccentric cam upon the lever to shut ball valve, and
2. The automatic action of the valve upon the discharge pipe thus making it a
perfect water waste preventing syphon cistern.
