page_text: I, JOSEPH HUSSEY, of "Mont Dore," Haverstock Road, Knowle, Bristol, in the
County of Gloucester, Warehouseman, do hereby declare the nature of this in-
ention to be as follows:-
This invention relates to float valves such as are used for regulating the water
supply to cisterns, and consists of an improved form of valve in which an air
chamber is employed, air being compressed in this chamber by the head of water
in the service pipe in such manner that the compressed air assists in rapidly
expelling the water, and preventing concussive action in the pipes when the valve
is falling to its seat.
In order to secure these advantages the upper part of the casing of the valve is
so constructed that an air chamber is formed above the valve head. The inlet
pipe may either enter above this, descending vertically in which case the air
chamber is annular surrounding the inlet pipe; or it may enter at the side of
or near the lower part of the air chamber.
On the lower side of the valve head a spindle is formed which passes down
through the centre of the valve opening; upon the lower end of the valve spindle
is formed a boss which is capable of being caused to slide up or down in suitable
guides formed in the valve casing. The boss is slotted at one point and into this
slot the end of the float lever projects in such manner that when the float rises or
falls the valve is also caused to rise and fall in an opposite direction. The outlet
pipe is arranged below the valve seat.
The float and lever may be of any convenient and known description.
The water entering above the valve compresses the air in the air chamber until
the pressure therein is sufficient to balance the head of water in the service pipe:
it being understood that in any case the pressure of the air serves to produce a
speedy exit of the water when the valve is open. In some cases the air chamber
is separated from the valve chamber by a diaphragm in which an opening is made
for the purpose of allowing the air to pass in and out.

page_text: 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 float valves such as are used for regulating the water
supply to cisterns, and consists of an improved form of valve in which an air
chamber is employed, air being compressed therein, by the head of water
in the service pipe in such manner that the compressed air assists in rapidly
expelling the water, and preventing concussive action in the pipes when the valve
is falling to its seat.
In order that my invention may be fully understood and ascertained, I append
a drawing in which my improved valve is shewn in vertical section.
A, indicates the cylindrical or other shaped chamber, the upper part a of which
forms a receptacle for containing the compressed air. This chamber A is secured
to the valve body by means of screwed ends as shewn, or by any other
convenient and suitable means. The lower part a¹ of the chamber A is occupied
by water. B, indicates a cylinder disposed in the valve body which acts as a
.. guide in which a piston or plunger b can slide. This piston is provided with a
stem which connects the plunger with the valve 62, this when closed resting
upon a seating 6 formed in the lower part of the body.of the valve chamber.
Formed in the body of the guide piston b is a slot or recess 6 for the purpose of
receiving the end c of the float lever which has the usual ball attached to its
end. The float lever C, is pivoted to the valve body and its end e passes through
an aperture in the side of the same and enters the slot or recess formed in the
piston b. D, indicates the supply pipe through which the water from the main pipe
or reservoir flows to the valve, and E, indicates the discharge spout or pipe
through which the water flows into the cistern.
The operation of my improved valve is as follows:-
When in its normal position, that is when the cistern containing the desired
quantity of water, the valve 62 is forced down upon its seating 63, sealed by means
of the end c of the ball lever being depressed, owing to the rising of the ball, which
floats upon the surface of the water, contained in the cistern.
When however the body of water in the cistern decreases and its surface level
falls to a certain extent, the ball is consequently lowered to the same level, thereby
causing the end c of the lever C to raise the piston and consequently open the
valve; the water then enters the pipe E, being forced by gravity and by the pres-
sure in the air chamber through the valve and spout to the cistern. As the water
rises in the cistern so will the rising of the float cause the end c to force the valve b²
down upon its seat thereby closing the same when the nominal quantity of water
has flown into the cistern.
In some cases the lower part of the valve chamber is divided from the upper
by a diaphragm which is perforated by one or more holes. In the drawing the
diaphragm is shewn in dotted lines and indicated by the letter A¹. The two parts
communicate through a centred opening.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. An improved float valve, in which the valve is normally held upon its seat
in its closed position by the pressure of a cushion of air upon the water which
occupies a position between the top of the valve, and the air cushion substantially
as described and shewn.
2. An improved float valve, in which when the valve is closed, the pressure of
a cushion of air tends to force it upon its seat, and when the valve is opened, tends
to force the water into the cistern, thus preventing or minimmising concussive action
in the pipe when the valve is falling to its seat, substantially as described and
shewn.
3. In a float valve the combination of the chamber A, the valve body a', the

page_text: guide B, the valve 62 having a stem b¹, the guide plunger or piston 6 formed
integrally with the valve and having a slot or recess 6, the lever C pivoted to
the valve body and having an end c which enters the slot 6 the inlet pipe 1), and
the outflow spout or pipe E, substantially as described and shewn.
4. In combination with the improved float valve as hereinbefore claimed, the
diaphragm A', substantially as described and shewn.
