Improvements in Apparatus for Flushing Closets, Urinals, Sinks, or
the like.
I, FRANK KINGSTON, of 22 Ethelbert Crescent, Cliftonville, Margate, in the
County of Kent, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to apparatus whereby a rush of water is discharged from a
vessel under pressure to flush the pan of a closet, urinal, sink or other place where
there may be deposit of offensive matter.
The accompanying drawing is a vertical section of flushing apparatus according
to my invention.
A strong vessel A is tightly closed by a cover C in which there is a passage B
communicating with a service pipe or cistern supplying water under pressure.
The passage B communicates with a central pipe D and with two branch
pipes E E, the lower ends of which have their mouths bent towards the central
line of the vessel.
At the bottom of the vessel is an outlet passage O covered by a valve F the
stem G of which extends up the pipe D and carries an elastic ball H. On the
stem G are fixed inclined blades or wings I on which the streams of water entering
the vessel by the pipes DE E impinge, causing the valve F to turn partly round,
its close fit upon the seating being thus ensured. As this result may be more or
less attained by the action of the stream descending the central pipe D, I in some
cases dispense with the pipes E E.
In the outlet passage O is pivotted a lever having an arm K extending under
the stem of the valve F. An axis L carrying an external lever M passes through
the side of the outlet with suitable packing which may be a tube of caoutchouc
having one end secured on the axis and the other end secured on a nozzle through
which the axis passes.
The axis L is not rigidly secured to the internal lever arm K but it has on it a
stud meeting a stud on K in the manner of a clutch so that on raising the external
lever M the arm N is also raised but the external lever can descend without
lowering the arm K.
Opposite to the arm K is another arm in the form of a blade N which, when in
the position shewn, obstructs the outlet passage, but, when in the position indicated
by the dotted lines N¹ leaves the passage unobstructed. The apparatus acts in the
following manner.
The valve F being closed, water enters the vessel A. and partly fills it, the space
above the water level containing air compressed to the extent due to the pressure
of the water supply.
When flushing is required, the external lever M is pulled up; this raises the
valve F and its stem G, compressing the elastic ball H which, closing the inlet
from the passage B, prevents farther supply of water from entering the vessel
during the time that the valve F remains open. By the opening of F the water
under pressure in the vessel A is allowed to issue, which it does with considerable
force pressing down the blade N to the position N' and thus, even when the
external lever M is let go, keeping the valve F open and the ball H closing B,
while the water continues to flow.
When the pressure of the issuing water on the blade N becomes insufficient, the
valve F closes, and the vessel becomes charged afresh.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. Flushing apparatus consisting of a vessel having an inlet for supply of water
under pressure and having at its bottom an outlet governed by a valve which can
be raised by an arm worked by an external lever and which, when so raised,
presses an elastic ball against the inlet so closing it, substantially as described.
2. In combination with the inlet pipe or pipes, inclined blades on the valve
.above referred to, substantially as and for the purpose set forth.
3. In combination with the arm and valve above referred to, a blade on which
the issuing water acts to keep the valve open during its flow, substantially as
.described.
