Improvements in Water Waste Preventing Flushing Apparatus.
1, SAMUEL STEVENS HELLYER, of 21 Newcastle Street, Strand, in the County
of London, Sanitary Engineer, do hereby declare the nature of my invention to be
as follows:-
The object of my invention is to provide a water waste preventing flushing
apparatus for use in flushing water closets, or for other analogous purposes, the
enid apparatus being very efficient and capable of being arranged in a compact
form, it being also capable of giving a free and rapid discharge without
objectionable noise.
According to my invention I provide a duplex syphon arrangement, the shorter
legs being situated in the cistern which receives the supply of water for each
flushing. The other legs descend, and join each other, and both merge into the
descending pipe by which the flushing water passes from the cistern and syphons
to the closet pan or other place to be flushed. One of the inlet legs of the syphons
in the cistern is provided with a valve or lifter which can be raised in the said
leg by a lever and chain or other suitable means, operated by the hand, or foot,
so that water contained in the said leg is lifted and forced over the bend of the
syphon and descends the other leg and enters the descending pipe and in so doing
draws the air from the other syphou and causes water from the cistern to enter it
and then both syphons act simultaneously to discharge the water from the cistern
into the closet pan or other place to be flushed. The leg of the syphon in which
the valve or lifter works, is made of a capacity sufficient to contain enough water
to have the effect of starting the syphons so that both syphons act to carry off the
water from the cistern and so a rapid and easy emptying of the cistern takes place.
The descending limbs of the syphons are separate from the body of the cistern and
are preferably outside the water containing space thereof, which enables the said
descending limbs to be made of a material such as iron, as should any leak occur
in these parts water will not pass away from the cistern through the said leak.
When compactness is desired a recess may be made in the cistern for the
accommodation of these descending limbs so that they do not project from the
general line of the cistern. The valve or lifter preferably consists of a disc in a
frame, which frame and disc are raised by the lever and chain or other operating
device connected with the frame, the said disc in lifting covering a hole in the
frame beneath the disc, but rising in suitable guides in the frame so that
afterwards water can pass into the syphon in which the valve is situated.

I, SAMUEL STEVENS HELLYER of 21 Newcastle Street, Strand, in the County
of London Sanitary Engineer, 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 :-
The object of my invention is to provide a water waste preventing flushing
apparatus for use in flushing water closets, or for other aunlogous purposes the
soid apparatus being very efficient and capable of being arranged in a compact
form, it being also capable of giving a free and rapid discharge without
objectionable noise.
I will describe my invention with reference to the accompanying drawings
Figure 1 of which represents in longitudinal vertical section Figure 2 in plan
and Figure 3 in elevation flushing apparatus constructed according to my
invention.
A is the tank or cistern which receives the water for each flushing the supply of
which water can be governed by the ball-cock B in the ordinary manner.
Into
this cistern descend the shorter or inlet legs C C of a duplex syphon the other
legs D D of which syphon descend and merge into one and into a descending
pipe E as shewn in Figure 3 by which the flushing water passes from the cistern
and syphons to the closet pan or other place to be flushed. One of the shorter or
inlet legs C of the syphon in the cistern is provided with a valve or lifter F
connected by a rod a and link a to one end of a lever G the outer end of which
lever is connected to a chain or other suitable means, operated by the hand, or
foot, to raise the said valve or lifter in the leg C of the syphon, so that water
contained in the said leg is lifted and forced over the bend of the syphon and
descends the other leg D, into the descending pipe E whilst in so doing air is
drawn from the other syphon thereby causing water from the cistern to enter it
and then both syphons act simultaneously to discharge the water from the cistern
into the closet pan or other place to be flushed. The part of the leg C of the
syphon in which the valve or lifter works, is made of a capacity sufficient to
contain enough water to have the effect of starting the syphon so that both
members of the syphon act to carry of the water from the cistern and so a rapid
and easy emptying of the cistern takes place. The descending limbs D, D of
the syphon are separate from the body of the cistern and should be arranged
outside the water containing space thereof as shewn which enables the said
descending limbs to be made of a material such as iron and so that should any
leak occur in these parts water will not pass away from the cistern through
the said lenk. When compactness is desired a recess is provided in the cistern
as shewn for the accommodation of the descending limbs D D of the syphons so
that they do not project from the general line of the cistern and permit of the
cistern being fixed close to the wall or surface adjacent thereto. The valve or
lifter in the leg C preferably consists of a disc carried in a frame which
frame and dise are raised by the lever and chain or other operating device
connected with the frame, the disc in lifting covering a hole in the frame
beneath the said disc, but the said dise being free to rise in the frame so that
afterwards the water can pass through the syphon in which the valve is situated.
The disc F is shewn as being guided by slots in it working against the arms f
forming a part of the frame. The said arins are preferably arranged as shewn in
the plan su that the disc tilts in lifting.

page_text: 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 [
claim is :-
The combination and arrangement of parts constituting the water waste preventing
flushing apparatus substantially as hereinbefore described and illustrated by the
accompanying drawings.
