SELF CLOSING BALL VALVE
Year: 1885

Sanitary Engineer do hereby declare the nature of my invention for SELF CLOSING
BALL VALVE to be as follows:-
=
The action of this Ball Valve, is that the lever connected to Ball, lifts a spindle
which opens a valve or seating allowing the water to flow until that in Cistern raises
the Ball. As the Ball rises it releases the lever from the spindle, which closes with
or without a spring as the pressure of water behind is alone sufficient to close it.
When this Valve or seating is closed, the water passes up a small channel over
another valve or seating, which is also closed by the pressure of water behind it,
so that no supply is obtained until the water in Cistern is reduced, & allows the
ball to fall, when the lever, by weight of ball alone, lifts the spindle & opens the
valves or seatings. I am thus enabled to obtain a full way in the valve & obviate
the objection to the great pressure required on the rubber seatings when the
floating power of Ball alone has to resist the pressure of water, often cutting the
rubber through after being only a short time in use & also closing the valve at
once, instead of it being done gradually by the old mode, thus meeting the
objectionable dribble.

Sanitary Engineer 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 :-
The action of this Ball Valve is that Lever A connected to Ball B lifts spindle C
as it falls which opens Valve or seating D allowing the water to flow until that in
Cistern raises the Ball. As the Ball rises it releases the end of lever from spindle C
which closes with or without a spring E as the pressure of water behind is alone
sufficient to close it When this Valve or seating is closed the water passes up a
small channel F over another Valve or seating G which is also closed by the
pressure of water behind it so that no supply can be obtained until the water
in Cistern is reduced and allows the Ball to fall when the Lever A by weight of
Ball alone lifts the spindle C and opeus the Valve or seating D, and by pressure
being released from Valve G the water passes through Valves D and G into
Cistern This Valve has a full water way through I can attach a Screw-down
Valve to bottom of Valve so that if necessary it can be repaired when fixed without
disconnecting it, and also by its means regulate the pressure.
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
1. The Valve closes at once, instead of being done gradually by the old mode, thus
avoiding the objectionable dribble, by the water's own pressure as soon as the
spindle is released by the water rising in Cistern instead of its being dependant
on the floating power of the Ball resisting the pressure of water, and thus obviate
the objection to the great pressure required on the rubber seatings which often
cute the rubber through after being only a short time in use, substantially as
described in the specification.
2. That I am able to gain the great advantage of having a full way through the
Valves, substantially as described in the specification.
