JOSEPH FRANCIS ANDREWS 5 Owens Row Clerkenwell E.C. Builder do hereby
declare the nature of this invention to be as follows:-
--
The subject of this invention is a flushing cistern & water waste preventer
suitable for flushing water closets & drains. It consists essentially of two parts riz.
Firstly, an outer fixed vessel or chamber which we call the container made of any
suitable material & of any convenient size or form having two flat sides. Secondly
an inner vessel or chamber which we call the receiver, also being made of any.
suitable material & being flat on the sides and partly round at the bottom some-
what resembling the sketch (Fig. 1) but this form need not be strictly adhered to.
The receiver is pivotted within the container as shewn A and balanced in such a
manner that the upper part of its circular end presses against one end of the
container as shewn B Fig. 2.
In this position the flushing water enters the receiver from a cistern or other
source of supply through a ball valve (preferably the Croydon pattern) fitted to
the end of the container C & so adjusted as to shut off the supply when the water
reaches the proper level in the receiver B Fig. 2. In operation the receiver (being
charged with water) is moved slightly forward by means of lever or other suitable
device Fig. 3 thus causing the water to flow into the shallow end of the receiver D
and thereby over balancing the weight at B & causing the receiver to tilt or fall
forward Fig. 4 & discharge its contents into the container & thence into the flush
pipe. The receiver is so adjusted that when in position to discharge the flush the
edge of the back or circular end acts upon the ball valve B Fig. 4 & thus shuts off
the supply of water until the receiver returns to its original position Fig. 2 which
it does by reason of its own weight as soon as the water has been discharged.
In our sheet of diagrams accompanying this Specification
Fig. 1 represents the receiver showing balance weight at B.
Fig. 2 is a section shewing receiver in position when charged and water level at B.
Fig. 3 section shewing receiver tipped forward to start the flush, and water
level at D.
