Improvements in Water Waste Freventers.
I, JOHN HOBBIS HARRIS, of Wantage, in the County of Berks, Registered
Plumber, do hereby declare the nature of this invention to be as follows:-
According to this invention there is pivoted within a cistern, a syphon, the
longer leg of which is adapted to normally bed upon an annular seat formed
within the cistern at the upper end of the discharge pipe and suitable means are
provided whereby the syphon can be rocked about a pivot so as to slightly raise
its longer leg from the seat, the arrangement being such that water will then
rush past the lower end of the long leg into the discharge pipe and thus rarify
the air in the syphon tube and start its syphonic action, which will continue
after the syphon has returned to its normal position and until the level of the
water in the cistern has been brought below the open end of the short leg of the
syphon. In one arrangement the annular seat is formed near one end of a
casting attached to the inner side of the cistern bottom, the seat being formed
with a tubular part projecting through the cistern bottom and having attached
to it the discharge pipe. The long leg of the syphon is shod with an annular
rubber collar and is arranged to bed vertically upon the said seat, while the
other leg, which is open to the contents of the cistern, is provided near to the
end of the tube with trunnions arranged at right angles to a plane containing
the centre lines of both syphon legs, the said trunnions resting in forked supports
or bearings formed upon the casting at any suitable distance from the above
mentioned annular seat. At the top of the syphon is a jaw to which is attached
by a pin an adjustable wire or rod connecting it with a bell crank or other
mechanical arrangement provided with a pull-chain, so arranged that, when the
chain is pulled, the rubber shod end of the syphon will be raised and the syphonic
action immediately set up. In order to prevent a continuous run of water being
obtained by fixing the pull chain in such a position as to hold up the long leg
of the syphon, the syphon may be so formed that, when the chain is pulled down,
the float-ball and lever of the supply valve, will be raised so as to shut off the
supply of water to the cistern so long as the chain is held down. This may be
effected by forming projections on the syphon which come in contact with the
float lever when the chain is pulled down.
Water waste preventers constructed as described work noiselessly and do not
require an overflow pipe.
In order to make my water waste preventer suitable for automatic flushing at
regular intervals I provide the cistern with a ball tap adapted to supply water
to the cistern as slowly as may be desired until the water therein is level with
the bottom of the bend of the syphon, but to then supply water at such a rate
that the water will rise rapidly in the cistern and start the syphonic action. Or
I may form a trap in the top of the syphon by making it with a downward bend
or otherwise, the effect being that a slow continuous supply of water will com-

page_text: press the air in the bend at the top of the short leg until the water in the trap
is forced into the long leg, and the syphonic action thus started.

Improvements in Water Waste Preventers.
I, JOHN HOBBIS HARRIS, of Wantage, in the County of Berks, Registered
Plumber, 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:-
According to this invention there is pivoted within a cistern, a syphon, the
longer leg of which is adapted to normally bed upon an annular seat formed
within the cistern at the upper end of the discharge pipe and suitable means are
provided whereby the syphon can be rocked about a pivot so as to slightly raise
its longer leg from the seat, the arrangement being such that water will then
rush past the lower end of the longer leg into the discharge pipe and thus rarify
the air in the syphon tube and start its syphonic action, which will continue
after the syphon has returned to its normal position and until the level of the
water in the cistern has been brought below the open end of the short leg of the
syphon.
In the accompanying illustrative drawings, Figs. 1 and 2 show respectively in
longitudinal vertical section, and plan, one construction of waste water preventer
according to this invention. Fig. 3 is a detail view of the syphon. Fig. 4 is a
part front view, and Fig. 5 a plan, showing the actuating parts arranged so
that the pull chain may be fixed either at the front or at the back of the cistern.
In the arrangement shown in Figs. 1, 2 and 3 the annular seat 1 is formed
near one end of a casting 2 attached to the inner side of the cistern bottom 3,
the seat being formed with a tubular part 4 projecting through the cistern
bottom to which is attached the discharge pipe 5. The long leg 6 of the syphon
is shod with an annular rubber sleeve or collar 7 that extends over the end of
the leg but not the opening therethrough and is arranged to bed vertically upon
the said seat 1. The other syphon leg 6, which is open to the contents of the
cistern, is provided near the end of the tube with trunnions 9 arranged at right
angles to a plane containing the centre lines of both syphon legs, the said trun-
nions resting in forked supports or bearings 10 formed upon the casting 2 at
any suitable distance from the above mentioned annular seat 1. At the top of
the syphon is a lug 11 to which is attached by a pin 12 an adjustable wire or
rod 13 connecting it with a bell crank 14 or other mechanical arrangement pro-
vided with a pull-chain 15, so arranged that, when the chain is pulled, the
rubber shod end of the syphon will be raised and the syphonic action immedi-
ately set up. In order to prevent a continuous run of water being obtained
by fixing the pull-chain 15 in such a position as to hold up the long leg 6 of
the syphon, the syphon may be so formed that when the chain is pulled down,
the float-ball lever of the water supply valve, will be raised so as to shut off the
supply of water to the cistern so long as the chain is held down. This may
be effected by forming on the syphon a projection 16 arranged to come in contact
with the float lever 10 of the ball tap 16b when the chain is pulled down.

page_text: In order to prevent noise, one or more saw cuts or slots 8%, say about 1½ inches
long by 16 of an inch wide, may be formed at the lower end of the inlet leg 6ª
of the syphon (see Fig. 3) for the purpose of admitting air thereto before all
the water has run out of the tank.
In the arrangement shown in Figs. 4 and 5 the rod 13 is jointed to an arm 17
keyed at its lower end to a spindle 18 mounted in bearings 19 at opposite sides
of the cistern. On one end of this spindle is fixed an arm 20 to the free end of
which the pull chain 15 is attached. By these means a partial rotation can
be given to the spindle 18, to operate the syphon, from a chain at one side of
the cistern instead of at one end thereof as in Figs. 1 and 2.
Water waste preventers constructed as described work noiselessly and do not
require an overflow pipe.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A water waste preventer comprising a cistern and a syphon that has its
longer leg normally bedded upon a seat within the cistern at the upper end of
the water discharge pipe and is adapted to be rocked about a pivot so that the
said longer leg can be slightly raised from its seat, the arrangement being such
that when the said longer leg is raised, water will rush past its lower end and
start the syphonic action which will continue after the syphon has returned to
its normal position and until the level of water in the cistern has been reduced
to a point at which air will be admitted to the shorter leg of the syphon, substan-
tially as described.
2. A water waste preventer of the kind specified in the preceding claim in
which the movable syphon is so formed and arranged in relation to the float
ball lever of the water supply pipe that when the chain used to tilt the syphon
is pulled down, the syphon will raise the float ball lever and cause the valve
to shut off the supply of water to the cistern as long as the chain is held down,
substantially as described.
3. My improved water waste preventer constructed and operating substantially
as hereinbefore described with reference to and shown in Figs. 1, 2 and 3 of
the drawings annexed or modified according to Figs. 4 and 5.
