Improvements in Valves for the Supply of Water to Waterclosets
and other Places.
I, GEORGE JENNINGS of Palace Wharf Stangate Lambeth in the County of Surrey
Sanitary Engineer do hereby declare the nature of this invention to be as follows:-
This Invention has for its object improvements in valves for the supply of water
to waterclosets and other places.
The improved valve is intended to remain open and continue the supply for a
regulated time after the handle of the closet has been released. The body or casing
of the valve is provided with an inlet and an outlet passage, the first is connected
with the supply pipe and the other with a delivery pipe connected with the pan.
Between the inlet and the outlet is an horizontal partition into which a valve seating
is inserted and a valve of considerable area closes upwards against this seating
moving in the direction of the flow. The valve is carried upon a stem which
projects upwards through a stuffing box and is jointed to a lever which is so weighted
that it tends to lift the valve to its seat.
When the handle of the closet is raised the weight also is lifted the valve is
removed from its seat and water passes to the pan. The cavity in the body or
casing of the valve is divided into two parts by a diaphragm of india rubber, in the
upper chamber above the diaphragm the valve works. Water is able to pass from
one side of the diaphragm to the other by a small passage regulated by a tap. The
lower end of the valve stem passes through the diaphragm and is connected with it
as hereinafter described. Hence the valve can only rise to its seat as fast as the
passage of water to the underside of the diaphragm through the regulating tap
permits it to do so. In order to allow of the rapid opening of the valve the valve
stem is arranged to pass by a circular opening through the centre of the diaphragm,
it is able to play through the opening for a short distance and water can pass by the
opening from one side of the diaphragm to the other. A valve seat is formed around
the opening on the undersido and upon the lower end of the stem a valve is fixed.
When the stem is pushed down to open the main valve the lower valve also leaves
its seat and allows the water to escape rapidly from the chamber beneath the
diaphragm consequently the diaphragm can yield rapidly to permit of the downward
movement of the stem. But when the stem on the release of the handle is drawn
upwards by the weight the valve at the lower end of the stem closes to its seat upon
the diaphgram and then the diaphragm can only yield slowly to permit the main
valve to close as water is able to find its way past the regulating tap to the
chamber beneath the diaphragm.
In order to prevent the main valve from clattering against its seat during the
closing which it is liable to do, the main valve is not fixed upon the stem but is
allowed a short play and there is a water passage of comparatively small area between
the main valve and the stem.
Below the main valve there is a third valve fixed upon the stem and this serves to
shut the passage through the main valve. When the main valve in closing approaches
its seat the pressure of the water beneath it lifts it to its seat before the stem has
completed its upward movement. Water then is still able to pass by the passage of
small area through the main valve until this in turn is closed on the completion of
the upward movement of the stem.
The valves are all faced with vulcanised india rubber and the seatings are of
vulcanite as in some waters metal seatings are liable to perish when working against
vulcanised india rubber.

Improvements in Valves for the Supply of Water to Waterclosets
and other Places:
1. GEORGE JENNINGS of Palace Wharf Stangate, Lambeth, in the County, of
Surrey 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 :---
This Invention has for its object improvements in valves for the supply of water
to waterclosets and other places.
The improved valve is intended to remain open and continue the supply for a
regulated time after the handle of the closet has been released. It is shown in the
annexed drawings Figure being a vertical longitudinal section and Figure 2 a
vertical transverse section. The body or casing a of the valve is provided witli an
inlet passage
b and an outlet passage e the first is connected with the supply pipe
and the other with a delivery pipe connected with the pan. Between the inlet and the
outlet is an horizontal partition d into which a valve seating is inserted and a valve e
of considerable area closes upwards against this seating moving in the direction of
the flow. The valve e is carried upon a stem e¹ which projects upwards through a
stuffing box and is jointed to a lever which is so weighted that it tends to lift the
valve to its seat.
The
When the handle of the closet is raised the weight also is lifted the valve e is
removed from its seat d' as shown in Figure 1 and water passes to the pan.
cavity in the body or casing of the valve is divided into two parts by a diaphragm fof
india rubber, in the upper chamber above the diaphragm the valve works. Water is
able to pass from one side of the diaphragm f' to the other by a small passage g
regulated by a tap 4. The lower end of the valve stem e¹ passes through the
diaphragm and is connected with it as hereinafter described. Hence the valve e
can only rise to its seat d¹ as fast as the passage of water to the underside of the
diaphragm through the regulating tap permits it to do so. In order to allow
of the rapid opening of the valve e the valve stem e' is arranged to pass by a circular
opening through the centre of the diaphragm it is able to play through the
opening for a short distance and water can pass by the opening from one side of
the diaphragm to the other. A valve seat is formed around the opening on the
underside and upon the lower end of the stem a valve his fixed. When the stem e¹
is pushed down to open the main valve e the lower valve also leaves its seat and
allows the water to escape rapidly from the chamber beneath the diaphragm con-
sequently the diaphragm can yield rapidly to permit of the downward movement of
the stem e¹. But when the stem e¹ on the release of the handle is drawn upwards by
the weight the valve at the lower end of the stem closes to its seat upon the
diaphragm and then the diaphragm can only yield slowly to permit the main valve e
to close as water is able to find its way past the regulating tap y' to the chamber
beneath the diaphragm f
In order to prevent the main valve e from clattering against its seat d during,
the closing which it is liable to do, the main valve e is not fixed upon the stem
but is allowed a short play and there is a water passage of comparatively small area
between the main valve e and the stem e¹.
Below the main valve e there is a third valve fixed upon the stem ef and this
serves to shut the passage through the main valve. When the main valve e in closing
approaches its seat the pressure of the water beneath it lifts it to its seat before
the stem has completed its upward movement. Water then is still able to pass by
the passage of small area through the main valve e until this in turn is closed on the.
completion of the upward movement of the stem e¹.
The valves are all faced with vulcanised india rubber and the seatings are of
vulcanite as in some waters metal seatings are liable to perish when working against
vulcanised india rubber..

page_text: 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 combination substantially as described of the main valve, the regulating
diaphragm moving with the main valve, the valve seat on the diaphgram and a
corresponding valve on the valve stem; the whole so arranged that whilst the main
valve is opening the water is able to pass the diaphragm freely but when it is closing
the water can only pass the diaphragm slowly by a regulated orifice as herein set
forth.
2. In combination with the mechanism claimed by the first claiming clause, the
auxiliary valve on the valve stem closing against a seating on the main valve; the
said main valve being loose on its spindle; and the whole being so arranged that
the main valve first closes with the flow and immediately afterwards the passage
through it is also closed by the auxiliary valve on the valve stem as herein set
forth.
3. In valves substantially as described and adapted for the supply of water to
waterclosets forming the valve seats of vulcanite as herein set forth.
4. Valves substantially as represented by the annexed drawings for the supply of
water to waterclosets and other places.
