Improvements relating to Cistern Ball or Float Valves.
We, WILLIAM HENRY WALLIS of 33 Northam Road, Southampton, Hot water
fitter and SIDNEY NICHOLS of 46 Brintons Road, Southampton, Builder, do hereby
declare the nature of this invention to be as follows:-
Our improvements are devised with a view to the construction of a cistern ball
valve in such a manner that, whilst controlling and regulating the passage noise-
lessly of fluid therethrough; at the same time, by the means hereinafter described,
free access is allowed to the device (and the flow of water stopped) to enable
repairs to be executed either to the valve or cistern, without interfering with, or
reducing the supply of water to other parts of the house or building, as occurs
with cistern ball valves as ordinarily constructed, involving shutting off the water
from the main or other source of supply.
In carrying out our Invention we employ a plug-provided with a screwed
spindle of any convenient size and shape, adapted to that portion of the usual
valve casing nearest the inlet thereto, said plug serving, to control, regulate, or
shut off as may be required, the flow of water passing to the cistern by way of the
ordinary piston valve actuated from the fulcrumed end of the ball or float lever.
The screwed spindle of the plug aforesaid is furnished with a lock nut to retain the
plug in the required position, a suitable washer being interposed between the outer
casing of the valve and the lock nut before referred to to prevent any possible
leakage of water through the screwed opening formed in the valve casing, in which
the screwed spindle of the plug aforesaid is fitted.
To effect the ready removal of the usual piston valve from its surrounding casing
in order to allow when required, of the valve being repaired, we slot the fulcrumed
end of the ball or float lever in such a manner as to cause same to assume a hooked
formation, by which means the lever may be readily detached or unskipped" from
the fulcrum around which it works, and so allow of the instantaneous withdrawal, in
the manner hereinafter described, of the piston valve from the casing; that is to
sayThe plug, provided at the end of the screwed spindle above referred to, is
screwed tightly against its seat, thereby shutting off the supply of water to the
cistern. The ball or float lever is then un-hooked from the pin or centre upon
which it works, consequently allowing of the ready withdrawal as before stated, of
the valve, which after being repaired is again replaced, and the slotted or hooked
end of the ball or float lever is connected to the pin or fulcrum upon which it
works. The locknut above referred to is then loosened and the screwed plug
adjusted to the required position to regulate the supply of fluid passing into the
cistern.

Improvements relating to Cistern Ball or Float Valves.
We, WILLIAM HENRY WALLIS, of 33 Northam Road, Southampton, Hot water
fitter, and SIDNEY NICHOLS of 46 Brintons Road, Southampton, Builder, 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, reference being also had to the figure shown in the annexed drawing
illustrative of our said Invention
Our improvements are devised with a view to the construction of a cistern ball

valve in such a manner, that, whilst controlling and regulating the passage noise-
lessly of fluid therethrough; it at the same time, by the means hereinafter described,
allows of free access being had thereto (and the flow of water stopped) to enable
repairs to be executed either to the valve or cistern without interfering with, or
reducing the supply of water to other parts of the house or building, as occurs
with cistern ball valves as ordinarily constructed, involving shutting off the water
from the main or other source of supply.
In carrying out our Invention we employ a plug, stopper or valve A provided
with a screwed spindle B of any convenient size and shape, adapted to that portion
of the usual valve casing nearest the inlet thereto, said plug serving to control,
regulate, or shut off as may be required, the flow of water passing to the cistern"
by way of the ordinary piston valve a actuated from the fulcrumed end of the ball
or float lever b. The screwed spindle B of the plug, stopper or valve A aforesaid is
furnished with a lock nut C, screwed washer, or equivalent, to retain the plug in the
required position, a suitable water tight washer c being interposed between the outer
casing of the valve and the lock nut, before referred to, to prevent any possible
leakage of water through the screwed opening formed in the valve casing, in which
the screwed spindle B of the plug A aforesaid is fitted.
To effect the ready removal of the usual piston valve a from its surrounding casing
in order to allow when required, of the valve facing d being replaced or repaired,
we slot the fulcrumed end of the ball or float lever 6 in such a manner as to cause
same to assume a hooked formation, by which means the lever may be readily
detached or "
unskipped" from the fulcrum e on which it works, and so allow of
the instantaneous withdrawal, in the manner hereinafter described, of the piston
valve a from the surrounding casing; that is to say -The plug A provided at the
end of the screwed spindle B above referred to, is screwed tightly against its scat,
thereby shutting off the supply of water to the cistern. The ball or float lever is
then detached from the pin or centre e upon which it works, consequently allowing
of the ready withdrawal, as before stated, of the piston valve e, which, after the
facing thereof has been repaired, is again replaced, and the slotted or hooked end
of the ball or float lever is connected to its pin br fulcrum e aforesaid. The lock
nut Cor equivalent above referred to is then loosened and the screwed plug B
adjusted to the required position to regulate the supply of fluid passing into the
cistern.
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
In ball or float cistern valves, the employment of a screwed spindle provided with
a plug, stopper, or valve-for independently stopping, retarding, and regulating the
passage of water to the cistern-in combination with a slotted detachable ball or
float lever, substantially as and for the purposes herein set forth.
