Improvements in Self Flushing and Pull Water Waste Preventing
Cisterns, Receptacles, or Tanks, specially suitable for Flushing
Water Closets, Urinals, Drains, Sewers, and such like purposes.
JOHN SMEATON, C.E. 56 Great Queen Street Lincolns Inn Fields London, W.C.
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:-
In carrying out my invention I prefer to arrange the syphon & valve seating
in the usual way in separate pieces from the cistern, although the same may be
forned with the cistern in one casting or piece. A ball valve or cock is mounted
in the cistern receptacle or tank in the ordinary way, with a small valve or priming
cock attached to the shank of the said ball valve or cock between the seating and
side of the cistern, receptacle or tank. When this is opened it keeps a constant.
stream running and as increased or decreased regulates the periodical discharge
of the flushing cistern, receptacle, or tank by gradually acting upon the float of
a second ball working on a pivot or centre & depresses the ball of the ball valve
or cock supplying the cistern receptacle or tank causing it to run a full stream,
as it rises this stream overflows the syphon charging the tail or flushing pipe
which has a discharge capable of emptying the cistern, receptacle or tank more
quickly than it fills, the ball drops again and begins refilling until the valve shuts,
when the priming cock again supplies sufficient water to raise the second ball
which in turn depresses the ball of the ball cock or valve & causes the operation to
go on of flushing.
In practice it has been found that the priming cock or valve is apt to become
stopped by dirt or grit.
To avoid this I prefer in my invention to arrange a small guide with slide and
screws to prevent the ball valve from closing completely this also regulates the
time flush and as the valve opens full at every flush the chance of the automatic
arrangement failing is avoided.
If the guide & slide shewn in drawings is not used the regulating screw may.
be applied to the ball valve.
This consists of an ordinary pattern ball valve with a screw cast in the body
& so arranged that the valve or lever of the ball valve when in the act of closing
strikes against the screw which prevents the valve from completely closing thus
allowing the regulating water to pass which set up the automatic flushing
action as described.
A pull & valve arrangement may also be adapted for hand flushing especially
useful for the better flushing of water closets, urinals & such like.
This may also be a self closing valve, so that no more than a certain quantity of
water can be discharged at each pull of the handle whether the handle is held or
not as shewn Figures 8, 9, 10, & 11, of my Specification No. 2355, 1880.
DESCRIPTION OF DRAWING.
A. is the cistern, tank, or other receptacle holding the flush.
B. is the lever attached by rod, chain or wire to valve, for the purpose of hand
flushing when desired.
C. is one leg of the syphon for discharging the contents of cistern, tank or other
rasentaala

page_text: E. E. are the floats or balls that control the flushing or discharge of the cistern
tank or other receptacle as also the ball valve or ball cock, when the priming cock
or ball valve are gradually letting in the regulating water, ball or float E on the
left depresses ball or float E on the right charging the syphon C. which in turn
overcomes the supply water from ball valve D. & priming cock F., should that
plan be adopted.
F. is the priming cock for regulating or timing the flush.
G. is the regulating screw of slide for regulating the shutting off of the ball
valve or cock D. & takes the place of the priming cock, by regulating the slide
the cock may be kept slightly open.
K. fixes the slide by pressure from above & holds it secure when once set.
H. is the regulating slide and centre upon which the operating or flushing float
works, actuating the right hand float E. in connection with ball valve.
I. is the inlet to syphon for starting by hand flushing by pulling lever B.
L. is the valve for closing opening into suction tail pipe, when hand flushing.
M. is the opening with seating upon which valve L. rests for closing said
opening.
N. is a stud cast or fixed on syphon for securing the regulating guide.
Having now particularly described my invention and the manner in which same
may be performed 1 claim
The invention of floating balls substantially as shewn & described also the
method of regulating the same to open the syphons by slide & guide substantially
as shewn and described & by arrangement of floats acting on each other as shewn
and for the manner and purpose set forth. The regulating screw may be applied
to the ball valve, so as to keep the valve seating free from the face of valve washer,
by a regulating screw pressing on the same.
The screw is cast & formed in the body of the valve in the usual way.
