I, JAMES WILLIAM BROADEY of Chell Street, Newton in the City of Manchester
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention for Improvements in Ball Valves and other water valves and taps
has for its principal object to construct a valve which shall not be liable to stick fast
when open, and by arranging the valve on the inner or pressure side of the seat to
cause it to be self-closing, and thereby to reduce the wear of the valve and render it
less liable to leak; and by constructing the valve detached from the plunger or
elevator to allow a certain amount of freedom or play between it and the float lever,
so that the vibrations of the float lever within certain limits when the cistern or
reservoir is full may not communicate corresponding vibrations to the valve.
In one form of Ball valve constructed according to my invention I employ a
horizontal barrel or casing connected to the supply pipe by means of a branch in the
ordinary manner. The one end of the barrel forms a chamber for the valve and is
closed by a screw plug or cover the whole being of a sufficient diameter to allow of
the valve being passed through. The opposito end of the barrel beyond the valve
seat is contracted in its diameter and is bored concentrically with the valve seat for
the reception of a hollow plunger, free to work backwards and forwards in a hori-
zontal direction. The outer part of this plunger is attached to one end of a ball
lever working in a helical or inclined slot in the valve barrel in such manner
that with each movement of the ball lever the plunger is caused to move in one
or the other direction, and thus move the valve to or from its seating.
The valve consists of a flat circular disc the underside of which is covered with
india-rubber or other suitable material for securing a tight joint on its seat and is
provided with a tail which passes loosely through the inner end of the beforementioned
hollow plunger.
At a short distance below its inner end the said plunger is partly cut away so that,
when it is elevated through the valve seat it raises the valve and allows the water to
pass through the said opening into and through its interior, and down into the cistern

page_text: It will thus be seen that as the level of the water in the cistern or reservoir varies
the plunger is forced forwards or backwards and the valve correspondingly opened or
closed, and that the valve, having the pressure of the water on its back tends to close
upon its seat and when closed to maintain that position, and so reduce the wear on it
and the seat.
Instead of the flat valve and seat described above I may employ a conical valve
and seat; or the valve may be spherical and supported on the before-mentioned
plunger.
When applying my improved arrangement of valve to ordinary water valves and
taps I connect to the plunger a screw or hand lever or other suitable device for
operating the valve in the place of the ball lever hereinbefore described.

I JAMES WILLIAM BROADEY of Chell Street, Newton in the County of Lancaster,
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 :-
My invention for Improvements in Ball valves and other water valves and taps
has for its principal object to construct a valve which shall not be liable to stick
fast when open and by arranging the valve on the inner or pressure side of the
seat to cause it to be self closing and thereby to reduce the wear of the valve
and render it less liable to leak; and by constructing the valve detached from
the plunger or elevator to allow a certain amount of freedom or play between it
and the float lever so that the vibrations of the float lever within certain limits
when the cistern or reservoir is full may not communicate corresponding vibrations
to the valve.
In one form of Ball Valve constructed according to my invention I employ a
horizontal barrel or casing connected to the supply pipe by means of a branch in
the ordinary manner. The one end of the barrel forms a chamber for the valve
and is closed by a screw plug or cover, the hole being of a sufficient diameter to
allow of the valve being passed through. The opposite end of the barrel beyond
the valve seat is contracted in its diameter and is bored concentrically with the
valve seat for the reception of a hollow plunger, free to work backwards and
forwards in a horizontal direction. The outer part of this plunger is attached to
one end of a ball lever and a pin is passed through the barrel and works in a
helical or inclined slot in the valve barrel in such a manner that with each move-
ment of the ball lever the plunger is rotated and consequently caused to move in one
or the other direction and thus move the valve from its seat or allow it to be forced
on to its seat.
The valve consists of a flat circular disc of india rubber or other suitable material
for securing a tight joint on the seat. The inner end of the beforementioned hollow
plunger is solid and when the ball is lowered raises the valve off its seat and itself
projects through the seat.
At a short distance from its inner end the said plunger is partly cut away to form
openings to its interior so that when it is forced through the valve seat it raises the
valve and allows the water to pass through the openings into and through its interior
and down into the cistern or reservoir, a second opening in the plunger being
then opposite an opening in the barrel leading to the cistern to be supplied with
water..
It will thus be seen that as the level of the water in the cistern or reservoir varies,
the plunger is forced forwards or backwards and the valve correspondingly opened or
closed and that the valve having the pressure of the water on its back tends to close
upon its seat and when closed to maintain that position and so reduce the wear on it
and the seat.
Instead of the flat valve and seat described above 1 may employ a conical valve
and seat; or the valve may be spherical and supported on the beforementioned

page_text: When applying my improved arrangement of valve to ordinary water valves and
taps I connect to the plunger a screw or hand lever or other suitable device for
operating the valve in the place of the ball lever hereinbefore described.
In the accompanying sheet of illustrative drawings.
Fig. 1 is a side elevation of a ball valve constructed according to my invention
and
Fig. 2 is a horizontal section of the same.
The horizontal barrel A is connected to the supply pipe by the branch B and is
provided with an exit pipe C. The one end of the barrel, into which the supply
pipe B leads, forms a valve chamber closed by a screw plug D and provided with a
seating, arranged between the supply and exit pipes B and C, for the india-rubber
valve E. The other end of the barrel beyond the valve seating is contracted in
diameter and in this part slides a hollow plunger F having closed ends. The outer
end of the plunger projects beyond the barrel and to this end is attached the ordinary
ball lever so that as the ball H rises or falls the plunger F is rotated backwards or
forwards in the barrel. A screw pin J passes through the barrel and its end enters
an inclined or helical slot L in the plunger F so that when the plunger is rotated in
the barrel it is also traversed forwards or backwards. The hollow plunger is provided
with openings O near its inner end and also with an opening X which when the ball
is in its lowest position and consequently the plunger F in its innermost position,
comes opposite the exit C. When the ball is in its raised position the inner end of
the plunger F is free of the valve E; but when the ball is lowered the plunger Fis
traversed forwards and forces the valve E off its seat and its inner end projects into
the valve chamber so that the water can pass freely from the supply pipe B through
the openings O hollow plunger F and opening X to the exit pipe C. When the ball
is again raised the inner end of the plunger F is withdrawn from the valve chamber
and the valve is forced by the pressure on to its seat.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
--
1. In ball and other valves and taps forcing the valve off its seat by means of
a pin taking into an inclined or helical slot in a plunger, the said pin being
revolved round the plunger, or the said plunger being rotated and the pin fixed
in the casing by means of a float, handle, or other convenient means substantially as
described.
2. A ball or other valve or tap consisting of a plunger having closed ends and an
inclined or helical slot into which takes a pin, the said pin being revolved round the
plunger, or the said plunger being rotated and the pin fixed in the casing, by means
of a float or handle and so causing the said plunger to be traversed endwise to force
the valve against the water or other pressure from its seat the water or other fluid
passing through openings in the plunger to the exit pipe the valve being returned to
its seat, on the return of the float or handle to its initial or normal position, by the
pressure substantially as described.
3. A ball or other valve or tap constructed substantially as described with reference
to the drawings.
