Improvements in Water Closets.
I, RICHARD BROWN EVERED, of 27 to 31 Drury Lane, in the County of
London, Brass Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates more particularly to water closets provided with an
outlet valve and having at the same time the advantages of a pedestal washdown
closet.
According to my invention I so arrange the aforesaid valve that when operated
it opens upwardly and assumes such a position as to be out of the way of the
outflowing feculent matter.
For this purpose the water closet may be constructed of earthenware, fire-clay,
enamelled iron or any suitable material and be provided with a U shaped outlet, to
the extremity of which is connected an inverted U shaped outlet pipe or valve-box
of iron, brass, or lead. At the point of junction of these parts I locate the valve
which preferably occupies an inclined position and is connected in any suitable
manner to the levers or appliances employed for actuating it. The seating for this
valve may be arranged in the valve box itself or may consist of a rim or bead
moulded or otherwise formed on the aforesaid U shaped bend leading from the
water closet to the said outlet pipe or valve box.
The overflow of the water from the closet is by means of trapped passages
formed in the walls of the pan, these passages meeting at the crown of the said
inverted U shaped outlet pipe or valve box at which point the overflow water enters
said pipe and flows onto the upper side of the valve thereby cleansing the latter of
any adhering matters.
Any suitable means may be employed for operating the said valve and admitting
water to the closet from a cistern or flushing tank, or from a supply valve instead
of a flushing tank. In some cases appropriate contrivances are provided for
delaying the closing of the valve. An after flush arrangement is also provided for
insuring that a large quantity of water shall always be left in the closet basin after
each flushing operation.

I, RICHARD BROWN EVERED, of 27 to 31 Drury Lane, in the County of
London, Brass Founder, 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 relates more particularly to pedestal washdown closets provided
with outlet valves.

page_text: According to my invention I so arrange the valve that when operated it opens
upwardly and assumes such a position as to be out of the way of the outflowing
feculent matter.
For this purpose the water closet pan is provided with a U-shaped outlet to the
extremity of which is connected an inverted U-shaped discharge pipe or valve box.
At the junction of these parts I locate the valve which preferably occupies an
inclined position.
The overflow of the water from the closet pan is by means of trapped passages
formed in the walls of the pan, and meeting at the crown of the said inverted
U-shaped discharge pipe or valve box, the overflow water falling upon the upper
side of the valve.
In order that the said invention may be clearly understood and readily carried
into effect I will proceed to describe the same by aid of the accompanying drawings
in which:-
Figure 1 is a vertical central section of one construction of water-closet embodying
my said improvements, and
Figure 2 is a rear side view of the said closet, the operating mechanism being
omitted.
Figure 3 illustrates to a smaller scale partly in side view and partly in section
one arrangement of my improved closet in combination with the flushing tank.
a is the water closet pan which may be constructed of earthenware, fireclay,
enamelled iron or any suitable material, b is the U-shaped outlet thereof, and c is
the inverted U-shaped discharge pipe or valve-box which may be formed of iron
brass or lead. These two U-shaped parts are connected by inclined flanged joints
as shown, and on the part & is formed a rim or beaded edge d forming a valve seat.
e is the outlet valve which is secured by means of a screw f and nut g to an arm h
connected to a rod or axle i in the valve box c. The valve thus opens upwardly
and it will be seen that the portion of the valve box in which the rod or axle i is
situated, is considerably wider than the mouth of the outlet b so that the valve is
able to open to such an extent that it lies entirely out of the way of the discharging
matters. On the end of the screw is fitted an india rubber cap; to form a stop
or buffer and prevent injury to the wall of the valve box, while on the face of the
valve is provided an indiarubber ring or washer & adapted to form a tight joint with
the beaded edge d when the valve is closed.
Obviously the valve seat may if desired be arranged in the valve box itself,
instead of upon the end of the outlet b.
Any suitable means may be employed for operating the valve e, simultaneously
with the admission of the flush water to the closet. Such an arrangement is shown
in Figure 3 in which the rod or axle i carrying the valve is connected with the
displacer of the flushing tank by a system of rods and levers. In this case the rod
or axle i extends through the wall of the valve box and is provided with an arm
having a curved slot in which works a pin m at one end of a lever n pivoted at o.
At its other end the lever carries a weight p and is connected by a rod q with the
lever which carries the displacer s of the Hushing tank t, the arrangement being
such that when the flushing handle, which is attached to the chain w is pulled, the
displacer is drawn down into the position shown in Figure 3. At the same time,
through the medium of the levers n and r and the rod q, the aforesaid pin m is
caused to descend in the slotted arm I and owing to the shape of the latter, the
axle is caused to turn and the valve is opened. When the handle is released the
weight p tends to close the valve and raise the displacer but these actions are
delayed owing to the fact that the displacer cannot rise again until the flushing
operation has been completed.
v, are the trapped overflow passages formed in the walls of the pan. These
passages meet in a common pipe w which opens into the upper part of valve box c
and discharges the overflow water on the top of the valve e thereby cleansing the
same of any adhering matters.
An after-flush arrangement of any suitable kind is provided, for ensuring that a

page_text: large quantity of water shall always be left in the closet pan after each flushing
operation.
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. A water closet having an inclined valve situated at the mouth of its outlet,
and arranged in such a manner that it opens upwardly substantially as described
and for the purpose specified.
2. The combination with the aforesaid upwardly opening valve, of the trapped
overflow passages in the closet pan for discharging the overflow water on to the
valve substantially as and for purpose set forth.
3. My improved water closet constructed and operating substantially as
hereinbefore described with reference to the accompanying drawings.
