PROVISIONAL SPECIFICATION.
Improvements in Water Waste Preventers for Cisterns, Tanks, and
the like.
I, JOSEPH HENRY GREEN, of 34, Sincil Bank, Lincoln, in the County of
Lincolnshire, Plumber, do hereby declare the nature of this invention to be as
follows:-
According to my invention the cistern is divided into two compartments or two
independent cisterns one of which is filled by ordinary means and the other by
means of a syphon. When it is desirable to discharge the flushing cistern a chain
is pulled which operates the outlet valve and at the same time depresses a plunger
attached to a weighted lever which plunger in its descent closes a door or chick
valve and prevents the water from rushing back into the supply cistern. As soon
as the handle is released the the plunger is raised and the water is again at liberty
to flow into the flushing cistern.

COMPLETE SPECIFICATION.
Improvements in Water Waste-preventers for Cisterns, Tanks, and
the like.
I, JOSEPH HENRY GREEN, of 34, Sincil Bank, Lincoln, in the County of
Lincolnshire, Plumber, 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 thereof, that is to say:-
This invention relates to means for preventing waste of water in cisterns tanks
and the like and in order that the same may be fully understood I have hereto
annexed a sheet of drawings in which Fig. 1 represents a sectional elevation of an
ordinary water closet cistern with my waste preventor applied and Fig. 2 is a plan
of the same.
a is the cistern to which water is admitted through a supply cock b until it
reaches a certain height when it is cut off by means of the float or ball c. d is
the outlet or discharge pipe open at the top and surrounded by an inverted
chamber e along with which is formed a small cistern or water-pocket f. This
pocket communicates with the outer cistern a by means of an opening near the
bottom, over which opening a door is hinged which yields to pressure from
without, but closes the opening on pressure being applied from within the cistern f.
A pillar screwed into the top of the chamber e supports the fulcrum of a lever j
one arm of which carries a counterbalance weight whilst to the other arm is
attached a chain k. At or near the middle of the latter arm is pivotted a rod
to the lower end of which is fixed a plunger m which fits, so as to move without
friction, within the small cistern. This cistern as will be seen is always in
communication with the vessel e through an opening e¹ formed near the bottom of
the partition which separates them.
Supposing the cistern to be empty it will be readily understood from what has
already been said that on water being admitted through the supply inlet 6 to the
cistern a the pressure thereof will open the door g and the liquid will rise equally
within each of the compartments a, f, e, until it is cut off by the ball cock, this
cutting off taking place when the water has risen say to the level indicated by the

page_text: dotted line a. or in any case before it reaches the top of the discharge pipe d
If now the chain k be pulled the plunger m will be caused to descend thereby
increasing the pressure in the compartment thereby closing the door g and the
water having no other outlet will be forced upwards in the chamber e and thence
down the discharge pipe d and this action having once commenced will continue
until the whole of the water in the cistern is "syphoned off."
In conclusion I may remark that the apparatus constituting my improved waste
preventer can be applied to or removed from any ordinary cistern in a few
minutes.
Having now particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The combination with a cistern such as a provided with a ball-cock or other
supply apparatus of a syphon discharger capable of being set in operation by
means of a plunger m working within a vessel substantially as for the purpose
herein described and illustrated by the accompanying drawings.
