Improvements in the Manufacture of Flushing Cisterns or Water
Waste Preventers.
BENJAMIN RICHARD BANKS of 29, Broadway, Deptford, in the County of Kent,
Metal Worker do hereby declare the nature of this invention to be as follows:-
--
I employ a Cylinder fixed in a Cistern of the requisite size which Cylinder has
a tube running up through its length and extending somewhat above the top, the
lower part of which Tube is screwed through the bottom of Cistern, in the Cylinder
is a hollow metal Float, Piston or Plunger, so made as to admit the before mentioned
Tube to pass through it. On the upper surface of the Float is fixed a tube of larger
dimensions than the other, and of such length as to be, when the Float is at its
highest position about 3 inches above the other Tube, on the upper part of the large
Tube is a cap, to which a Chain Tube or rod is attached, and which runs through the
fixed Tube and bottom of Cistern, and which on being pulled brings down the said
Float, Pision, or Plunger, as required. In the lower part of the Cylinder is fitted a
valve hereinafter called a Foot Valve-a foot valve opening inwards, a syphon is
fixed to bottom of Cistern the short arm of which extends to within one fourth of an
inch of bottom of Cistern, the long arm of same projects through the Cistern to the
outside, the Cistern being supplied with water by means of any ordinary Ball Cock
or Valve but the inlet is carried down to the bottom of Cistern and terminates in a
perforated pipe, so as to avoid the noise occasioned by the water in filling the Cistern.
When the flushing is required to be performed the Chain Tube or rod is pulled
which brings the Float Piston or rod down the Cylinder and so closing the Foot
Valve, presses the water through channel connecting Cylinder with short leg of
Syphon thus starting it The pressure of the air on the outside, opening the Foot
Valve and maintaining the action of the Syphon until the water in the Cistern is
exhausted thus ensuring a thorough flush. When the water is readmitted, the
Cylinder is filled through the Foot Valve, and the Float or Piston rises again to its
position when it is again ready to act.

BENJAMIN RICHARD BANKS of 29 Broadway Deptford in the County of Kent
Metal Worker 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 carrying out my Invention 1 employ a Cylinder A fixed in a Cistern of the
requisite size in such a manner as to allow a communication between the lower part
of such Cylinder and the Cistern by means of a channel or passage B partially below
such Cistern and which terminates in a short pipe C projecting upwards into the short
leg of a Syphon D with which the Cistern is furnished.
This said Cylinder is fitted in the lower part with a valve E hereinafter called a
Foot Valve opening inwards and has also a Tube running up through its length F &
extending somewhat above the top the lower part of which Tube is fixed through
the bottom of the Cistern. In the Cylinder is a hollow metal Float Piston or
Plunger G so made as to admit the pipe before mentioned to pass through it. On
the upper surface of the Float is fixed a Tube H of larger dimensions than the other
and of such length as to be when the Float &c. is at its highest position about
3 inches above the other Tube. On the upper part of the larger Tube is a Cap to which
a Chain Rod or Tube K is attached and which runs through the fixed Tube and
which on being pulled brings down the said Float &c. as required. The Cistern is
supplied by means of an ordinary Ball Cock or Valve but the inlet for such purpose
is conducted into a receiver J which is constructed with an outer Casing L and which
receiver is fixed to the inside of the Cistern. When the receiver is full it overflows
into the above mentioned Casing and through the perforated bottom of which into the
Cistern so avoiding any noise or splashing.
When the flushing is to be performed the Chain or Rod is pulled which brings the
Float &c. down the Cylinder & so closing the Foot Valve presses the water down
through the passage into the short leg of Syphon thus starting it when the pressure
of the air on the outside opening the Foot. Valve maintains the action of the
Syphon until the water in the Cistern is exhausted thus ensuring a thorough flush.
When the water is readmitted the Cylinder is filled through the foot valve
and the Float rises to its upper position in the Cylinder when it is again ready
to act.
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
By these means an absoluic prevention of waste of water and also a noiseless &
perfect method of Flushing Water Closets Drains &c.
