Street and Eddystone Sanitary Engineering Works, Howland Mews East,
both in the County of Middlesex. IMPROVEMENTS IN VALVES AND OTHER
ARRANGEMENTS SPECIALLY USEFUL FOR WATERCLOSETS, URINALS, AND SUCH LIKE
PURPOSES."
My Invention consists mainly of improved form of water waste preventing and
regulating valves to be applied to chamber or cistern that holds the supply; also
the valve is applied to water closets, urinals, and such like. I prefer when it is
applied to water closets to fit the valve in a chamber cast with the pan and plug
chamber, said chamber being between the pan and plug chamber. Or the valve-
chamber with plug chamber may be cast separate from the pan. To this chamber
a ventilating arm is applied. One form of my improved water waste preventing
valves consists of a valve seating fixed in the chamber or cistern that holds the
water for supply. To this valve seat a pipe is attached, the other end of which can
be connected to the water-closet pan, urinal, or other arrangement, and on this
valve seat within the water chamber a valve is fitted to act to cut off the water
supply to the water closet pan, urinal, or other arrangement. The top of this valve
is preferably a globular form, though it might be of other form. To the top of this
valve a flexible chamber, preferably of india rubber, is fitted, having one or more
holes or orifices in it to admit air or water, though in lieu of holes or orifices a
communicating pipe with regulating cock or valve can be employed. This flexible
chamber has a weight attached to it, at the underside of which a recess or hollow is
by preference formed. To the the top of such weight a rod or wire or other suitable
connection is attached to lift the same, as also the india rubber chamber and valve

page_text: attached, to allow the water to pass out of the chamber or cistern in which it is
fitted to the pan or chamber, by which action flushing takes place, and the india
rubber chamber is gradually filled with air or water passing into it through the
holes in the same, and the valve is closed as soon as so filled, thereby regulating the
quantity of water that shall be supplied to the water closet pan or chamber. When
the weight is allowed to act on the india rubber chamber by the rod, or wire, or
connection being released, and so forcing the water or air out of the india rubber
chamber, the valve is ready again for another action. Another form of valve consists
of a diaphragm or disc valve, with regulating cocks and other cocks or valves
working in connection with air chambers or vessels, that is, a chamber or vessel to
each cock or valve. The diaphragm or disc valve is constructed with an inlet pipe
in the centre, and the outlet from such diaphragm being formed around the inlet,
and over these apertures a sheet of india rubber or other flexible material is fitted,
and held over the same by the outer edge or flange of a hollow cover fitted over
the same, and from the inlet pipe a water pasage is formed. To the top side of this
fixed diaphragm or disc valve, and in this water passage, a small cock is fitted
which I call the regulating cock, by which the quantity of water to act on the top
side of the diaphragm valve to close it is regulated, and from the top side of the
diaphragm or disc valve, and in the cover of the same, a water passage is formed to
a chamber connected with the same, in which chamber one or more cocks or valves
(preferably two) is or are fitted to work with one lever and in such a manner that
when one of such cocks is open to the water passage in the diaphragm valve cover
the other is closed. And in connection with each of these cocks or valves there is
a small air vessel which receives the water passing through the cock to which it is
attached, and when either of the cocks is shut off from the water passage to the
top side of the diaphragm, the water is released from the air vessel attached to such
cock through an aperture in the cock or valve in which the cocks or valves are
fitted. At the same time as the water passes on to the top side of the diaphragm
or disc it also passes into the air vessel or vessels, and compresses the air therein to
a pressure equal to the column of water in the supply pipe, and so acts on the top
side of the diaphragm or disc valve, forcing such valve down onto the inlet and
outlet, and closing the same in a given time by the quantity of water allowed to
pass the regulating cock. Further, my Invention comprises improved arrangements
in valve closets with valve box and trap substantially in one, whereby the overflow
is made more secure, and the action of flushing out is better effected.

by the said John Smeaton in the Great Seal Patent Office on the 10th

JOHN SMEATON, of the Firm of William Smeaton and Sons, of 24, Moorgate
Street and Eddystone Sanitary Engineering Works, Howland Mews East,
both in the County of Middlesex. "IMPROVEMENTS IN VALVES AND OTHER
ARRANGEMENTS SPECIALLY USEFUL FOR WATERCLOSETS, URINALS, AND SUCH LIKE
PURPOSES."
The first part of my Invention consists of improved form of water waste
preventing and regulating valves to be applied to chamber or cistern that holds the
supply. Also the valve is applied to water closets, urinals, and such like. I prefer
when it is applied to water closets to fit the valve in a chamber cast with the pan
and plug chamber, said chamber being between the pan and plug chamber. Or the
valve chamber with plug chamber may be cast separate from the pan. To this
chamber a ventilating arm is applied. One form of my improved water waste
preventing valves consists of a valve seating fixed in the chamber or cistern that
holds the water for supply. To this valve seat a pipe is attached, the other end of
which can be connected to the water closet pan, urinal, or other arrangement, and
on the valve seat within the water chamber a valve is fitted, to act to cut off the
water supply to the water closet pan, urinal, or other arrangement. The top of this
valve is preferably of globular form, though it might be of other form. To the top of
this valve a flexible chamber, preferably of india rubber, is fitted, having one or
more holes or orifices in it to admit air or water, though in lieu of holes or orifices a
communicating pipe with regulating cock or valve can be employed. This flexible
chamber has a weight attached to it, at the under side of which a recess or hollow
is by preference formed. To the top of such weight a rod or wire or other suitable
connector is attached to lift the same, as also the india-rubber chamber and valve
attached, to allow the water to pass out of the chamber or cistern in which it is fitted
to the pan or chamber, by which action flushing takes place, and the india rubber
chamber is gradually filled with air or water passing into it through the holes in the
same, and the valve is closed as soon as so filled, thereby regulating the quantity of
water that shall be supplied to the water closet pan or chamber. When the weight is
allowed to act on the india rubber chamber by the rod or wire or connector being
released, and so forcing the water or air out of the india-rubber chamber, the
valve is ready again for another action. Another form of valve consists of a
diaphragm or disc valve with regulating cocks and other cocks or valves working
in connection with air chambers or vessels, that is, a chamber or vessel to each cock
or valve. The diaphragm or disc valve is constructed with an inlet pipe in the centre,
and the outlet from such diaphragm being formed around the inlet, and over these
apertures a sheet of india-rubber or other flexible material is fitted and held over
the same by the outer edge or flange of a hollow cover fitted over the same, and
from the inlet pipe a water passage is formed. To the top side of this fixed
diaphragm or disc valve and in this water passage a small cock is fitted which I call
the regulating cock, by which the quantity of water to act on the top side of the
diaphragm valve to close it is regulated, and from the top side of the diaphragm or
disc valve, and in the centre of the same, a water passage is formed to a chamber
connected with the same, in which chamber one or more cocks or valves (preferably
two) is or are fitted to work with one lever and in such a manner that when one of
such cocks is open to the water passage in the diagraphm valve cover the other is
closed. And in connection with each of these cocks or valves there is a small air
vessel or chamber which receives the water passing through the cock to which it is
attached, and when either of the cocks is shut off from the water passage to the

page_text: fitted. At the same time as the water passes onto the top side of the diaphragm
or disc it also passes into the air vessel or vessels, and compresses the air therein to
a pressure equal to the column of water in the supply pipe, and so acts on the top
side of the diaphragm or disc valve, forcing such valve down into the inlet and
outlet, and closing the same in a given time by the quantity of water allowed to
pass the regulating cock.
Further, my Invention comprises improved arrangements in valve closets with
valve box and trap in one, whereby the overflow is made more secure and the action
of flushing out is better effected.
DESCRIPTION OF THE DRAWINGS.
Fig. 1, front sectional view of one form of valve.
Fig. 2, side sectional view of one form of valve.
Figs. 3 to 7 show various forms of closets to which valves shown in Figs. 1 and 2
are applied. A is the disc or diaphragm secured between two metal parts of valve.
To the underpart of diaphragm A, seating A' of india-rubber or other material is
secured; B, B', cocks working in connection with the chambers C, C¹, above
diaphragm A; D inlet pipe, and E outlet around the inlet. Both inlet D and outlet E
are covered by the disc or valve A; F, regulating cock; G, lever. In Figs. 3, 5, 6,
and 7, I show the application of said valve to various forms of closets. The
Drawings show the arrangements by which when the handle or pull H is raised the
lever G is also raised, establishing a communication between the chambers C or C',
as the case may be. When one chamber is full, the disc A is operated upon by
means of the water passing through the cock F onto the top side of the disc or
diaphragm A. When the handle is released the lever G drops, establishing commu-
nication between the other chamber and the top of the disc or valve A, thereby
allowing an afterflush to the water closet pan or other arrangements, and by the
same operation and at the same time the water from the chamber is discharged
through the orifice H, in Fig. 3 into the valve chamber, in Fig. 5 into the trap of
the overflow, in Fig. 6 into the valve chamber, in Fig. 7 into the overflow in
connection with valve chamber. The pressure on the top side of the disc or
diaphragm A is sufficient to effectually close both the inlet and outlet, the result being
that leakage cannot take place around outlet E. Fig. 4 shows a closet to which this
valve can be applied. In this arrangement the rod in connection with the tumbler
of closet is employed for actuating the valve shown in Figs. 1 and 2. The water
from the chambers C and C' passes directly into the container, the after flush being
obtained as before described. Figs. 8 and 9, sectional elevation of globular valve,
applicable to cisterns or chambers, as shown in Figs. 10, 11, and 12. In Fig. 8
the globular part is expanded, in Fig. 9 contracted; K, metal portion fixed to hollow
To
spindle K, to which is attached flexible portion L, preferably of india rubber.
part L is attached the valve M, which rests on seating N in cistern (Figs. 10 and 11).
The valve M is provided with spindle M', which works in hollow spindle K', so as
to guide the valve. It is evident that other suitable arrangements for guiding the
valve may be used. O, lever connected to valve P. When the lever is operated
upon by means of chain arm or connector Q the valve is raised, taking the form as
in Fig. 9, thus establishing a communication between the cistern or chamber
(Figs. 10, 11, and 12). The globular part by orifice R gradually fills, causing the
valve to fall onto its seating N, thus closing the opening N, and thereby shutting
off the communication with the supply pipe. In Fig. 11 two valves are shown, by
which when one is closed, the other is opened by weight S on the lever O, and the
after flush is given while the valve is falling onto its seat. In Fig. 12 the valve
is enclosed in a chamber with inlet D¹ and outlet E¹. This arrangement is suitable
for high pressure.

Invention and in what manner the same is to be put in practice, I hereby declare
that I claim the said Invention of "Improvements in Valves and other Arrange-
ments specially useful for Water closets, Urinals, and such like Purposes," wherein
the important points or features are the valves shown in Figs. 1, 2, 8, and 9, and
their application to water closets, cisterns, or chambers, substantially as shown and
described.
