S.W. do hereby declare the nature of this invention to be as follows:-
The object of this invention is to obtain a more perfect flush with far greater
facility than has hitherto been practicable.
This I effect by fitting a cistern with a syphon consisting of two tubes fitting
one within the other so as to rise and fall together-The inner tube has a shoulder
or collar formed on its base which fits into a bell mouthed or other suitably shaped
socket piece attached to the bottom of the cistern-The shoulder or collar formed
round the base of the inner tube is fitted with a rubber or leather washer which
forms an elastic seating or such collar or shoulder may be ground into the socket
piece and the elastic seating dispensed with-The syphon may be worked either
automatically or otherwise.
The operation of my invention is as follows:-In order to start the syphon it is
only necessary to raise it when the water at once flows into the month piece after
which by allowing the syphon to drop the water continues to discharge itself from
the cistern so long as any remains therein by rising through. the outer and
descending through the inner tube thus creating a continuous and perfect flush.

S.W. 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
2
The object of this invention is to obtain a more perfect and noiseless flush than
has hitherto been practicable.
Fig. 1 of the accompanying drawings shews a view in sectional elevation of a
cistern fitted with my improved rising and falling syphon flushing apparatus closed
and arranged to be worked by hand.
Fig. 2 shows an external elevation of such apparatus complete.
Fig. 3 shews a view in sectional elevation of such apparatus open and fitted
with auxiliary automatic mechanism as presently described and
Fig. 4 shews a plan view of the same when so fitted with such automatic
mechanism.
..
To effect the before mentioned object I fit a cistern A with a syphon flushing
apparatus consisting of two tubes, a, b, fitting one within the other and connected
by means of stay rods a or their equivalents so as to rise and fall together when
actuated as presently described-The inner tube has a collar c formed on or fixed
to its lower end which forms a valve. This valve fits into a béll mouthed or other
suitably shaped socket piece d fastened to the bottom of the cistern by means of a
Bcrew nut & or its equivalent-The valve is provided with a rubber or leather
washer which forms an elastic seating therefor-Or such valve may bé ground
into the socket piece and the elastic seating dispensed with. The apparatus may
be worked either by hand or automatically.
When worked by hand a suitable lever and cord 1, , or their equivalents are
fitted thereto as shown in Fig. 1 and to start the syphon it is only necessary to
pull the cord or its equivalent thus raising the syphon when the water at once
flows into the mouth piece after which by releasing such cord or its equivalent and
allowing the syphon to drop the water continues to discharge itself from the cistern
by rising through the outer and descending through the inner tube thus creating a
continuous noiseless and perfect flush.
A corresponding action may however be produced automatically and periodically
when desired This I effect by fitting the syphon with an air tight outer casing k
hereafter termed a float as shewn in Fig. 3-This float is fitted with suitable
connecting rods and counterpoise weights, h-i. or their equivalents so arranged
as to allow the float to rise and fall as the tank is filled or emptied thus
automatically actuating the syphon To ensure the proper action of the float
1 surround the same with a guide ring m carried on stay rods n which ring
serves to hold the float in position while to produce a regular automatic
periodical action of the syphon the ball valve or its equivalent is set so as to cause
the syphon to act at given intervals say once in every hour or otherwise as desired
When so worked automatically I likewise fit the cistern with a suitable stop valve
and connections indicated at r Fig 3 so as to readily shut off the supply when the
apparatus is not in use.

page_text: One great advantage of my invention is that owing to the rising and falling
action of the apparatus consequent upon its improved construction and arrange-
ment as herein before described I entirely obviate the unpleasant noise hitherto
attendant upon the working of syphon apparatus and this I do as effectually when
flushing with large bodies of water; (as in the case of sewers and drains,) as when
only using small quantities for closets and other purposes.
When the cistern is of my improved registered recessed form at the bottom as
shewn in the accompanying drawings-it forms a perfect trap to prevent the
escape of the sewer gas as the syphon ceases to discharge the water from the
cistern when the water is reduced below the level of the bottom of the outer tube
of the syphon while the water remaining in the recess or well formed in the bottom
of the cistern forms an effective water seal that effectually prevents the escape of
the sewer gas.
I would here observe that I do not confine myself to the precise mechanical
details herein before described and shewn as the same admit of variation without
departing from the nature of my invention..
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1° A rising and falling syphon flushing apparatus constructed combined arranged
and fitted substantially in the manner hereinbefore described and shewn at Figs. 1
and 2 of the accompanying drawings.
2° Fitting the same with auxiliary automatic mechanism substantially in the
manner herein before described and shewn at Figs. 3 and 4 of the accompanying
drawings.
