Improvements in or connected with Storage Cisterns or
Water-waste Preventers.
We WILLIAM STEPHEN VEARS, Plumber, of 5 The Parade, New Southgate, and
CHARLES BROWN, and GEORGE SWEETLAND, Builders, both of 1 Bellevue Road, New
Southgate, in the County of Middlesex, do hereby declare the nature of this invention
to be as follows:-
This invention relates to certain improvements in or connected with storage cisterns
flushing tanks or water waste preventers and has for its object to provide a simple
arrangement for ensuring constant supply, for the prevention of waste, and for
effectually obviating the fouling of the general or main water supply.
According to our improvements we use a covered water tight cistern with or
without au after flush" chamber at the bottom and provided with a discharge pipe
and one or more supply pipes. The latter is or are connected to an internal fixed
chamber with valve seatings, through which and a stuffing box on the cover passes a
spindle carrying a fixed valve controlling the discharge orifice and an adjustable
valve acting upon the supply orifice and controlling the supply. This valve is acted
upon by a spring and so adjusted as to effectually shut off the supply before the
delivery valve commences to open. The valve spindle is or may advantageously be
nade hollow with escape openings to prevent the action of contained air affecting the
valves. To the top of the valve spindle is fitted the usual lever pivotted on a fulcrum
and having an operating chain or equivalent at its free end. The lever is counter-
weighted and it and the valves are arranged so as to keep the discharge valve normally
closed and the supply normally open, thus the cistern is always subject to the pressure
of the supply and a ball valve working in a casing with air holes is provided to retain
the contents when the cistern is full and admit air during discharge.
A great advantage of this arrangement is that no overflow pipe is required. Any
quantity of the contained water can be drawn off by the above described arrangement,
but in some cases we provide for the discharge of a definite volume each time the
lever is depressed.
This may be effected by fitting the above described arrangement with slight
modifications as a service box of defined size into a larger cistern containing a greater
volume and applying an auxiliary valve for charging same after use; or by the
application of a valved syphon fitted into the cistern and adapted to discharge a given
volume at each operation of the lever; or by other suitable means.

Improvements in or connected with Storage Cisterns or
Water-waste Preventers.
We, WILLIAM STEPHEN VEARS of 5 The Parade New Southgate London Plumber,
and CHARLES BROWN and GEORGE SWEETLAND both of Bellevue Road New Southgate
London Builders, 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 :-
This invention relates to certain improvements in or connected with storage cisterns

page_text: flushing tanks or water waste preventers and has for its object to provide a simple
arrangement for ensuring constant supply, for the prevention of waste, and for
effectually obviating the fouling of the general or main water supply. We will
fully explain our invention in reference to the accompanying drawings in which
Figs. 1 and 2 are sectional elevations of cisterns fitted with our improvements, Fig. 3
is an elevation of Fig. 2, and Fig. 4 is a detail: Similar letters refer to similar parts
in all of the figures.
According to our improvements we use a cistern A with a cover a adapted to be
fitted watertight, and with or without an after flush chamber a' at the bottom, and
provided with a discharge orifice d and pipe and one or more supply pipes SS; the
latter is or are connected to an internal chamber C fixed vertically above the discharge
orificed and having at its base valve seatings c; we use a spindle B carrying two
valves, the lower one V is fixed and controls the discharge orifice d, and the upper
one V is adjustable and acts upon the seatings and controls the supply through
C and S. The valve V1 is acted upon by a spring b and its position upon the spindle B,
i.e. its "lift," is adjustable by means of the nut b' for which the spindle is screwed.
Referring to the construction illustrated in Fig. 1.--The spindle B passes through
the fixed chamber C (which acts as a guide) and a stuffing box a² on cover a: The
valve spindle B is or may be with advantage made hollow with air escape openings at
its top to prevent the action of contained air affecting the valves and causing them to
jump or pulsate. To the top of the valve spindle B is fitted the lever L pivotted on
a fulcrum at and having the usual operating chain at its free end. An alternative
mechanical arrangement for operating the valve spindle B is illustrated in Figs. 2 and 3.
The spindle B is extended below the bottom of cistern A and connected to the operating
lever L by the levers 12, the latter of which is carried through the cistern in a pipe p.
The lever L is or may be counter weighed if required and it and the valves V V₁ are
arranged so as to keep the discharge d normally closed and the supply S normally
open as illustrated by this arrangement the closed cistern A is always subject to the
full pressure of the supply and a ball valve W is provided working in a casing W
with air holes w to retain the contents when the cistern is full and admit air during
discharge. In the arrangement illustrated in Figs. 2 and 3 the casing of the ball
valve is utilized as a fulcrum for lever L. The position of the valve V₁ on spindle B
is so adjusted by nut as to completely and effectually shut off the supply at c
simultaneously with the opening of the discharge, and during the whole time the
discharge is open the valve V is held firmly up against the seatings c by the
compressed spring b; thus it is impossible for foul or other gas to pass from any
source up the supply pipe S to the main supply, and no overflow pipe is required
which is an important advantage of this invention. We may in some cases where it
is required to completely shut off the supply before the discharge is opened apply
below the discharge valve V a short plunger t Fig. 4, of a length about equal to the
lift of valve V fitting and working in the orifice d and which would not be entirely
withdrawn therefrom until the supply c was fully shut off by valve V₁, and a further
pull on lever L would then fully open the discharge orifice d; by the above described
arrangements any quantity of the water contained in A can be drawn off by holding
the lever L depressed.
•
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
(1) A storage cistern or water waste preventer consisting of a closed watertight
tank with supply and delivery orifices and air valve, the said orifices being controlled
by two valves V1 V arranged upon one spindle B the former V₁ being adjustable and
adapted to completely shut off the supply at c simultaneously with or before the
opening of the discharge d and to maintain the supply shut off so long as the
discharge is open, the said spindle B being operated substantially as set forth in
reference to the figures.

substantially as set forth in reference to the figures.
