the nature of our invention for "AN IMPROVED WATER WASTE PREVENTER AND
FLUSHING CISTERN to be as follows:-
:-
"
This invention has for its object an improved water waste preventer and flushing
cistern,
The improved apparatus consists of a cistern of a capacity to contain the
quantity of water required to be delivered at one time. This cistern is supplied
from a main or other source by means of a double supply. valve-There is in this
double valve a passage with a conical seating which receives a valve at the end of
a spindle which is capable of movement vertically through a stuffing box. Beyond
this first valve there is a second consisting of a plunger operated by a lever upon
which there is a ball float. The float as it rises floating on the water operates by
means of the shorter arm of its lever on the plunger and thrusting it inwards closes
the supply orifice in opposition to the flow of the water.
There is also at the bottom of the cistern an exit aperture provided with a draw
off valve. This valve consists of a weight on the under side of which there is a
hemisphere of india rubber and below this again a metal valve with wings
entering into the outlet passage. The weight when free to do so descends carrying
the metal valve and india rubber hemisphere into the outlet passage in such manner
as to close it effectually.
For the purpose of drawing off the water the valve is lifted by a stem on the
lower end of which there is a nut. This nut is contained in a cavity within the
weight and the stem is jointed to the lever. When it is required to draw water
from the cistern the outer end of the lever is drawn down by means of a chain
or other connection. The lever passes through two elongated eyes; one of these is
in a fixed support immediately above the plunger of the ball valve-the other is
at the upper end of the spindle valve already referred to.
Between the two eyes the lever has upon it a roller or rollers serving to prevent
end wise movement of the lever through the eyes.
The operation of these parts is as follows:-
When the chain is first drawn down the lever fulcrums upon the lower part of
the eye of the spindle valve and this valve is consequently depressed until the

page_text: inlet passage is completely closed. Then the further movement of the lever
causes the outlet valve to be lifted and the contents of the cistern are then
discharged.
On the other hand when the chain is released the lever moves in a contrary
direction under the influence of a weight the outlet valve closes and the lever
takes a bearing upon the lower part of the eye on the stationary support which
then becomes the fulcrum. The movement of the lever continues after the outlet
valve has closed and the spindle valve again rises.
An Improved Water Waste Preventer and Flushing Cistern.
We SAMUEL BENJAMIN GOSLIN Engineer and JAMES JOHN BROWN, Foreman
Brass Finisher both of Jewin Crescent in the City of London do hereby declare 1
the nature of our invention for "AN IMPROVED WATER WASTE PREVENTER AND
FLUSHING CISTERN" and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
This Invention has for its object an improved water waste preventer and flushing
cistern.
The improved apparatus consists of a. cistern of a capacity to contain the
quantity of water required to be delivered at one time. This cistern is supplied
from a main or other source by means of a double supply valve. There is in this
double valve a passage with a conical seating which receives a valve at the end of
a spindle which is capable of movement vertically through a stuffing box. Beyond
this first valve there is a second consisting of a plunger operated by a lever upon
which there is a ball float. The float as it rises floating on the water operates by
means of the shorter arm of its lever on the plunger and thrusting it inwards closes
the supply orifice in opposition to the flow of the water. Around the plunger
and valve seating there is an annular space.
There is also at the bottom of the cistern an exit aperture provided with a
draw off valve. This valve consists of a weight on the under side of which there
is a hemisphere of india rubber and below this again a metal valve with wings
entering into an outlet passage. The weight when free to do so descends carrying
the metal valve and india rubber hemisphere into the outlet passage in such manner
as to close it effectually.

page_text: The drawing is a vertical section of a water waste preventer or flushing cistern
constructed in accordance with our invention.
a represents the sides of a cistern of a capacity to hold the maximum quantity
of water which it is desired to draw off at one time-to economise space on the
drawing a part of this cistern and some other portions of the apparatus are
omitted.
b is the water supply passage connected with a water main or other source.
c is a stop valve and d is a valve controlled by a ball or float; the valves c and d
operate as a double supply valve and the cistern can only receive water when both
are open. The valve c is at the end of a spindle which passes through a stuffing
box c¹, e is the float which controls the valve d it is carried by a bent lever and
the shorter arm of the lever acts against the valve to hold it to its seat when the
float is in its upper position and the cistern is full. The annular space around the
seating for the plunger or valve d allows a free flow of water until it is cut off.
There is an exit aperture in the bottom of the cistern at a'; the exit valve
provided to close it consists of three parts:-a hollow weight fl a hemisphere of
vulcanised india rubber f2 and a metal valve with wings f³; the valve f³ enters
into the passage a' which it loosely fits. A stem passing through the part f³
connects the parts fl and f³ and the part f2 is solid with the exception of the
passage provided for the stem. When the outlet valve closes the flow is mainly
arrested by the metal valve f³ and the passage is afterwards completely closed by
the india rubber hemisphere f².
g is a rod entering a hole in the top of the weight f¹; in this hole the rod is
able to play freely. The rod has a nut on its lower end within the cavity of the
weight so that the rod when sufficiently raised carries the outlet valve up with it.
The rod g is jointed to the lever h which is weighted at h¹ so that the end of the
lever to which the rod is connected preponderates. The lever h passes through two
elongated eyes i and k one of which is on a fixed support and the other is on the
stem of the stop valve c. There are rollers 2 on the lever h between the eyes i
and k. is a chain by which the outer end of the lever h is drawn down when it
is desired that water should be delivered.

page_text: When the chain is pulled the lever fulcrums on the bottom of the eye k holding
the stop valve e to its seat and afterwards lifts the outlet valve. On releasing the
chain the counter weight h' causes the lever to return, it still fulcrums in the eye k
until the outlet valve reaches its seat and then the lever is supported by the lower
part of the eye and the valve c rises.
This arrangement effectually prevents waste of water arising from the supply
valve and the outlet valve being simultaneously open.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
(1.) A water waste preventer or flushing cistern having a draw-off valve, a ball
valve and a stop valve (the latter together forming a double supply valve) and
having also a lever which opens the draw off valve and when so operating has
for its fulcrum the stem of the stop valve which consequently is then held to
its seat.
(2.) A water waste preventer or flushing cistern having a draw off valve
consisting of a weight, a hemisphere of india rubber and a metal valve with wings
entering and loosely fitting the outlet passage.
(3.) A water waste preventer or flushing cistern substantially as described and
shown.
