to be as follows, that is to say :-
My said invention has for its object to diminish or prevent noise and waste in
connection with watercloset and other cisterns.
In my improved water-supply apparatus a plunger or cylindrical valve piece is
arranged to close against the water pressure by coming into contact with a seat or
edge encircling an inlet aperture or port, this port being somewhat larger than the
bore of the supply pipe, or of some contracted part through which the water has to
pass to reach the port. With this construction an extremely small movement of
the valve piece is sufficient to allow the maximum desired stream of water to pass.
The water leaves the valve box through a separate spout; and the valve piece has
its outer end reduced in diameter and extending through a cap or ring screwed or
otherwise fixed on the valve box. The valve piece is acted on by the lever of a
ball float, the lever being centered on the valve-box cap in a position very near the
centre of the valve piece; and the lever acts by means of a small horn which bears
without rubbing on the centre of the outer end of the valve piece. With this
arrangement little if any noise is caused by the water entering the cistern, and the
valve is very quickly closed as soon as the float rises high enough for its lever to
begin to act on the valve piece.
The discharge from the cistern is effected by means of a siphon the parts of and
connected with which may be constructed and arranged according to any of the
various plans which are in use or known. I however cause the lever or rod which
effects the starting of the siphon, to also act upon a stopcock or valve upon the
water supply pipe in a manner to stop the supply of water during the time that the
siphon is running. The water has to pass the stopcock or valve last mentioned
before reaching the float valve or cock which is not interfered with by the siphon-
actuating mechanism; and the said stopcock or valve also serves for shutting off
the water supply when the float valve or cock requires to be examined or
repaired.

Improvements in Water-supply and Discharge Apparatus, applicable
to Watercloset or other Cisterns.
1, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew,
North Britain, 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, that is to say :-
My said invention has for its object to diminish or prevent noise and waste in
connection with watercloset and other cisterns.
In my improved water-supply apparatus a plunger or cylindrical valve piece is
arranged to close against the water pressure by coming into contact with a seat or
edge encircling an inlet aperture or port, this port being somewhat larger than the

page_text: bore of the supply pipe, or of some contracted part through which the water has to
pass to reach the port. With this construction an extremely small movement of the
valve piece is sufficient to allow the maximum desired stream of water to pass. The
water leaves the valve box through a separate spout; and the valve piece has its
outer end reduced in diameter and extending through a cap or ring screwed or
otherwise fixed on the valve box. The valve piece is acted on by the lever of a
ball float which is connected in a particular manner hereinafter described.
The discharge from the cistern is effected by means of a siphon and I cause the
lever or rod which effects the starting of the siphon to also act upon a stopcock or
valve controlling the water in a manner to stop the supply of water to the float
valve during the time that the siphon is running.
And in order that my said invention and the manner of performing the same may
be properly understood 1 hereunto append a sheet of explanatory drawings to be
hereinafter referred to, and showing my improved water-supply and discharge
apparatus.
Figure, 1, of the drawings is a vertical section of one example of my improved
water-supply valve,
Figure, 2, being a vertical section and Figure, 3, a perspective view of a second
example.
Figure, 4, is a vertical section of a third example of my improved water-supply
valve.
Figure, 5, is a vertical section of a watercloset cistern and its accessory parts.
Figure, 6, is a vertical section of another watercloset cistern and its accessory
parts.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In my improved water-supply valve shown in Figure, 1, a plunger or cylindrical
valve piece, A, is arranged to close against the water pressure by coming into
contact with a seat or edge, B, encircling an inlet aperture or port, C, this port
being somewhat larger than the bore of the supply pipe, or of a contracted part, D,
through which the water has to pass to reach the port. With this construction an
extremely small movement of the valve piece, A, is sufficient to allow the maximum
desired stream of water to pass. The water leaves the valve box, F, through a
separate spout, G; and the valve piece, A, has its outer end reduced in diameter
and extending through a cap, H, screwed or otherwise fixed on the valve box.
The valve piece, A, is acted on by the lever, J, of a ball float, the lever being
centered on the valve box cap, H, in a position very near the centre line of the valve
piece; and the lever, J, acts by means of a small horn, L, which bears without
appreciable rubbing on the centre of the outer part of the valve piece, A,, which is
formed with a slot, M, for the horn to project into. With this arrangement little
if any noise is caused by the water entering the cistern, and the valve, A, is very
quickly closed as soon as the float lever, J, rises high enough to begin to act on the
valve piece. The supply valves shown in Figures, 2, 3, 4, 5, and, 6, act in a similar
manner to that hereinbefore described but in each case there is fitted an additional
valve for a purpose hereinafter explained.
The discharge from the cistern, N, (Figure 5) is effected by means of a siphon, P,
the parts of and connected with which may be constructed and arranged according
to any suitable one of the various plans which are in use or known. 1 however
cause the lever, Q, which effects the starting of the siphon, P, to also act upon a
stop valve, R, arranged in the supply-valve box, F, (Figures 2, 3, and, 4,) in 'a
manner to stop the supply of water during the time that the siphon is running.
The lever, Q, acts by means of a pin, S, on a lever, T, which is fixed to the
spindle, V, of the stop valve, R. The water has to pass the stop valve, R, before
reaching the float valve, F, which is not interfered with by the siphon-actuating
mechanism; and the said stop valve, R, also serves for shutting off the water supply
when the float valve or cock, F, requires to be examined or repaired. As shown in
Figure, 2, the opening and closing of the valve, R, takes place, when the spindle, V,

page_text: is turned, by the action of a screw thread on the spindle in an internal screw thread
in the valve box. Owing, however, to the small valve movement required in con-
sequence of the relatively large size of the port, C, the screw thread may be of fine
pitch without requiring much turning movement of the spindle, and without the
valve being liable to open by the water pressure as is the case with a screw thread
of larger pitch. If preferred the valve, R, may be arranged to close with the
pressure.
In Figure, 4, the valve box, F, is shown as also fitted with a stop valve, R, in
this case working vertically. As shown in Figure, 6, the lever, Q, when operated
for starting the siphon, P, is arranged to close the valve, R, a pin, S, fixed in the
lever and working in a slot in a link, W, jointed to the valve spindle, V, pressing
down that spindle on the lever, Q, approaching its lowest position and making the
valve, R, close the seat at the upper side of the port, C. The valve, R, is provided
with a leather or other washer, X, on its upper side which when the valve, R, is
raised prevents the water from reaching the stuffing box of the spindle, V.
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 watercloset or other cisterns, a water-supply valve having a valve piece
movable by a float lever against the water pressure and closing on a seat encircling
a relatively large aperture or port, the float lever being arranged to act on the
valve piece only when nearly at its highest position substantially as and for the
purposes herein before described.
2. The combination and arrangement of parts constituting my improved water-
supply apparatus for watercloset and other cisterns substantially as hereinbefore
described with reference to Figures, 2, 3, and, 4, of the accompanying drawings.
3. The combination and arrangement of parts constituting my improved water-
supply and discharge apparatus for watercloset and other cisterns substantially as
hereinbefore described with reference to Figures, 5, and, 6, of the accompanying
drawings.
4. In water-supply and discharge apparatus of watercloset and other cisterns
fitting an additional stop valve to the supply pipe or passage the valve being
connected to and acted on by the lever which effects the starting of the siphon,
substantially as and for the purposes herein before described.
