PROVISIONAL SPECIFICATION.
Improvements in or connected with Flushing Cisterns for Water
Closets.
I, PAUL GADOT, of 16 Rue Drouot, Paris, in the Republic of France, Engineer,
do hereby declare the nature of this invention to be as follows:-
The so-called flushing cisterns employed more particularly for water closets
mainly in the system of "all to the sewer" have for their object to discharge
from a suitable height a certain quantity of water which washes away the solid
or liquid substances contained in the basins or pans.
Hitherto these apparatuses have been constructed of various types which always
deliver each time the same quantity whatever may be the nature of the substances
to be flushed away, the consequence of which is in most cases an excessive con-
sumption of water.
The improvements made by me in these apparatuses have for their object to
remedy this drawback. They consist in forming cisterns of any known or suitable
types but by means of which, according to the nature of the substances to be
flushed away, a greater or lesser discharge of water may be obtained, such dis-
charge varying for instance from eight litres when solid matters are to be washed
away to two litres when only liquids are to be removed.
These improvements may also be applied to already existing apparatuses which
are transformed in such a way as to allow of the results hereinbefore specified
being obtained.
The invention will be described with reference to various types of cisterns.
1ST EXAMPLE.
BELL ARRANGEMENT.
In this arrangement a cistern, which is suitably filled with water by means of
a tap and bell, supports a bracket on which pivots a lever operated by a
pull
chain or cord. This lever supports a bell, and a sleeve washer inay rest freely on
the lower flange of the bell.
If the handle of the pull cord be pulled, the bell is lifted sufficiently sharply to
cause the displacement of the water which it contains, the lower opening being.
obstructed by the washer. The result of this sudden displacement is that the
water is discharged into the interior of the funnel, which forms a siphon with
the bell; the siphon then commences to draw thus causing the discharge of the
cistern by means of the funnel and pipe which descends to the pan.
It must be noted that the volume of water discharged from the cistern is always
the same at each operation.
In the modified arrangement according to my invention there are two bells
one of which is arranged to discharge say 8 litres of water and the other to
discharge only 2 litres for instance.
These different discharges may be obtained for instance either by means of

page_text: In this arrangement when the handle is pulled the valve is raised the water
flows through the pipe, and this jet then acts by suction in the arm of the siphon and
causes it to act; the water then continues to run away and the cistern is emptied
to the lower edge or level of the siphon, the latter then ceases to act and the water
accumulates afresh. It must be again noted here that the volume of water
discharged from the cistern is always the same at each operation I have called
this a siphon arrangement because the siphon is particularly visible but in both
the preceding arrangements there is equally siphonage.
In the modified arrangement according to my invention one of the two siphons
is arranged to discharge 8 litres of water for instance and the other only 2 litres.
These different discharges may be obtained either by making use of two arrange-
ments in which the siphons, valves, etcetera, are at different levels, or by making
use of similar arrangements in which, for instance, the immersed arms of the
siphons are bored with holes situated at different heights, or oven by any other
means which may be easily varied or even by a combination of several of these
means.
4TH EXAMPLE.
VALVE ARRANGEMENT.
In this arrangement, a lever operates a valve so that the flush of water only
takes place while the handle is held down.
I will not mention the modifications, improvements or details of this apparatus
as a whole which may be varied indefinitely, thus for instance the valve may
be sometimes made annular bored in its centre and the rod hollow with a plug at
top capable of intercepting the return of the air during the discharge and so
forth; I do not mention them because this patent does not deal with the mechanism
itself.
I admit that the quantity of water discharged may vary in this case according to
the force and duration of the pull on the handle but in general and in practice

page_text: people do not reflect so much, a strong prolonged pull being given (more usually
too much than not enough from fear of being deceived) and the cistern is entirely
or almost entirely emptied, that is to say down to the level of the valve seat, the
more so as theso apparatuses necessitate a wide opening of the valve for their
efficacious working.
In the modified arrangement according to my invention one, of the two valves
is arranged for instance for a discharge of 8 litres and the other, of only 2 litres.
These different discharges may be obtained either by placing the valves at
different heights, or by different means, or even by the combination of several
of these means.
It must also be noted that the two apparatuses placed in the same cistern may
be different, thus for instance, one may be a suction bell and the other a valvė.
This point is of great importance not only as regards the construction of flushing
cisterns arranged according to my invention but also and more particularly.. from
the point of view of the conversion of already existing apparatuses, or the con-
struction of apparatuses of known types to which it may be desired to add my
improvements.
In fact if for the modification of already existing or designed apparatuses or
those already in course of execution, it be found that the solutions hereinbefore
described aro somewhat difficult and cumbersome, (it must be noted however'
that they are only described as examples) other, perhaps simpler ones may be
imagined. As examples of new forms I will mention some other solutions which
may also of course be employed with new cisterns. These solutions are simple
enough and consist in adding to existing flushing cisterns at any suitable point
a second flushing pipe with separate valve and hand pull, the valve for discharging
the water and which is arranged at a level which will give only a small flushi
may be vertical or oblique; or the valve may be horizontal and open in rising
or it may be horizontal and open by descending.
It is evident therefore that various solutions may be designed.
I may also remark that in the case of existing apparatuses or those already
planned in order to profit by my invention, the problem is in fact simple enough
as it is generally only a question of adding little device enabling a less
voluminous flush of water to be discharged for instance 2 litres; and consequently
as almost always the apparatuses to be added are only placed a little below the
level of the water they have only to bear an almost insignificant pressure.
In all the solutions the two pull cords or chains and their handles may be
similar, but it will be evidently preferable to make them dissimilar, for instance,
to make the cord corresponding to the 8 litres flush shorter, so that it will be
less easily grasped and pulled and its handle may also differ from the other än
order to avoid their being mistaken.
The pipe and apparatus corresponding to the 2 litres flush may if desired be of
less section than the pipe and corresponding arrangement of the 8 litres flush,
but that presents no alvantage but rather the contrary and they may be inserted
in separate cisterns connected by pipes instead of both in one cistern. The two
pipes (large and small flush) may only meet at the pan or basin of the closet, or
even before that, but in such a way then as not to hamper the working of either
of them or cause them to work in an irregular manner, which may be prevented
by placing for instance on the large flush pipe or on both pipes, an enlargement
forming an air reservoir.
I reserve the right of varying the forms dimensions proportions and accessory
parts and employing for their construction any material which I may deem suitable.

Improvements in or connected with Flushing Cisterns for Water
Closets.
I, PAUL GADOT, of 16 Rue Drouot, Paris, in the Republic of France, 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 so-called flushing cisterns employed more particularly for water closets
have for their object to discharge from a suitable height a certain quantity of water
which washes away the solid or liquid substances contained in the basins or pans.
Hitherto those apparatuses have been constructed of various types which always
deliver each time the same quantity whatever may be the nature of the substances
to be flushed, away, the consequence of which is in most cases an excessive con-
sumption of water.
The improvements made by me in these apparatuses have for their object to
remedy this drawback. They consist in forming cisterns of any known or suitable
types but by means of which, according to the nature of the substances to be
flushed away, a greater or lesser discharge of water may be obtained, such dis-
charge varying for instance from eight litres when solid matters are to be washed
away to two litres when only liquids are to be removed.
These improvements may also be applied to already existing apparatuses which
are transformed in such a way as to allow of the results herein before specified
being obtained.
The invention will be described with reference to the accompanying drawings,
in which various types of cisterns are shown in diagrammatic and sectional
elevations, both before and after their conversion by the addition of my improve-

page_text: Figure 5 shows a type of this arrangement on the present system and Figure 6
the same but modified by the application of my improvements.
In this arrangement, Figure 5, when the handle P is pulled the valve e is raised,
the water flows through the pipe f, and this jet then acts by suction in the arm g
of the siphon and causes it to act; the water then continues to run away and the
cistern is emptied to the lower edge or level n of the siphon, the latter then
ceases to act and the water accumulates afresh. It must be again noted here that
the volume of water discharged from the cistern is always the same at each
operation. I have called this a siphon arrangement because the siphon is par-
tícularly visible but in both the preceding arrangements there is equally siphonage.
In the modified arrangement, Figure 6, according to my invention, one of the
two siphons is arranged to discharge 8 litres of water for instance and the other only
2 litres. These different discharges may be obtained either by making use of
two arrangements in which the siphons, valves, etcetera, are at different levels as
in Figure 6, or by making use of similar arrangements in which, for instance, the
immersed arms of the siphons are bored with holes situated at different heights,
or even by any other means which may be easily varied or even by a combination
of several of these means.

handle P, of cord b is held down. m is a washer...
In the modified arrangement, Figure 8, according to my invention one of the
two valves is arranged for instance for a discharge of 8 litres and the other of only 2
litres. These different discharges may be obtained either by placing the valves
at different heights, as shown in Figure 8, or by different means, or even by the
combination of several of these means
It must also be noted that the two apparatuses placed in the same cistern may be
different, thus for instance, as shown in Figure 9, one may be a suction bell and
the other a valve..
This point is of great importance not only as regards the construction of flushing
cisterns arranged according to my invention but also and more particularly from
the point of view of the conversion of already existing apparatuses, or the con-
struction of apparatuses of known types to which it may be desired to add my
improvements.
In fact if for the modification of already existing or designed apparatuses or
those already in course of execution, it be found that the solutions hereinbefore
described are somewhat difficult and cumbersome, (it must be noted however that
they are only described as examples) other, perhaps simpler ones may be imagined.
As examples of new forms I will mention some other solutions shown in Figures 10,
11, and 12 which may also of course be employed with new cisterns. These
solutions are simple enough and consist in adding to existing flushing cisterns
at any suitable point (see Figure 10), a second flushing pipe with separate valve
and hand pull, the valve for discharging the water and which is arranged at a
level which will give only a small flush may be vertical or oblique; or as shown
in Figure 11, the valve may be horizontal and open in rising, or as shown in
Figure 12 it may be horizontal and open by descending.
It is evident therefore that various solutions may be designed.
Figures 14, 15 and 16 are respectively a longitudinal sectional elevation, trans-
verse sectional elevation, and sectional plan view, taken respectively on the
lines 1-2 of Figure 16, and 3-4 of Figure 14, of a modification of the arrange-
ment of the bell and suction apparatus on the old system shown in Figure 13.
In this case, Figure 13, when the handle P is pulled, the bell A is raised and
with it the valve S; the water of the reservoir is then discharged round the conical
ajutage D, producing by suction the action of the central branch of the siphon,
from whence it results that when the bell A and the valve S again drop, the flow
continues, and the reservoir is discharged down to the lower edge of the bell, the
siphon then ceases to draw, and the water accumulates afresh.
In order to obtain with the same apparatus two discharges, as desired, either
of 8 litres or of 2 litres, for instance, I combine the following mechanical arrange-
ment shown in Figures 14, 15 and 16.
The modified apparatus comprises two levers L and 7 corresponding respectively
to the large and small discharge and operated by handles P and p. The two
levers L and are connected by a chain T passing through an upper ring a of the
bell A and serving to lift it. Each of the levers has also at its inner end a
link B and, respectively, serving to communicate an oscillating movement to
a balancing sector M which can oscillate on trunnions forming part of the bell A.
This sector has on one of its sides opposite to the lever L a valve C, serving to
close or open, according to the position of the sector, a hole O formed in the bell
and consequently to allow the unpriming of the siphon in case of small discharges.
The apparatus works as follows:-
Supposing the handle p of the small discharge be pulled, the bell A is raised
by the chain T and the water commences to flow as in the case of the old arrange-
ment, but the lever 1, pulling the link b, causes the balancing sector M to move
to the left, as shown in dotted lines in Figure 14, and the small valve C uncovers
the opening O formed in the bell.
The water then commences to run, but when it reaches the level of the hole O,

page_text: which is open, air enters into that part of the siphon and unprimes it, so that
the discharge is stopped precisely by this hole, which may be bored at any suitable
height in order to have such an ancunt of discharge as may be determined upon.
On the other hand, if the lever L for the large flush be pulled, the bell is raised
and water commences to flow, but the lever L has also pulled the link B, which
causes the balancing sector M to fall to the right, as shown in full lines in
Figure 14, and the valve C then closes the orifice 0. Therefore the water continues
to flow even when its level reaches the orifice seeing that the latter is closed
and the reservoir is consequently completely discharged, or rather down to the
lower edge of the bell A which has again dropped.
In the case of the modification shown in Figure 17, the lever / acts both for
raising the bell and lifting a little valve C which closes a discharge O admitting
the air. The bell L on the contrary returns the valve into its former position.
Figure 18 is a view in sectional elevation of another form of siphon apparatus,
and Figure 19 is a similar view of the same modified by the addition of my
improvements. In the case of Figure 18, when the handle P is pulled, the valve S
is raised, and water is discharged at D. The jet acting then by suction on the
branch G of the siphon causes it to act; the discharge of water then continues
and the reservoir is emptied down to the lower level of the siphon. The siphon
then ceases to act, and the water accumulates afresh.
In the case of Figure 19, the lever L oorresponds always to the large discharge
and lever to the small discharge. The two levers are also connected by a chain T
which serves to pull up the valve S. If for instance the handle of the small
discharge be pulled, the valve S will be raised and water commence to flow
in the manner described in the former apparatus, Figure 18, but the lever at
the same time has pulled the link band caused the balancing sector to move and
fall to the left as shown in dotted lines, so that the small valve C no longer stops
the hole formed in the branch E of the siphon.
Water therefore commences to flow, but when its level reaches the hole 0,
which is open, air enters the siphon and causes it to cease to act so that the
delivery is arrested precisely by this hole which is formed at any suitable height
in order to have such a small delivery as may be determined upon.
In the other case, if the lever L of the large supply he pulled, the valve S is
raised and water commences to flow, but the lever L has drawn up the link l' thus
causing the balancing sector M to fall to the right as shown in full lines, and the
valve C thus stops the hole 0, whilst the water which has commenced to flow
continues to do so even when its level has reached the hole 0, seeing that the
latter is stopped, and the reservoir is then completely discharged, or rather down
to the lower lip of the siphon.
In the modification shown in Figure 20, the sector acts by stopping or unstopping
a pipe 0, the mouth of which is directed downwards.
In the modification shown in Figure 21, there is no sector, but in the case of the
small discharge it is necessary to make two movements, one which is effected
by the lever L serving to raise the hell, the other which is effected by the lever
serving to uncover the opening 0, the valve C having an elastic seat closing of
itself when the lever is no longer acted upon.
These few examples embrace almost all cases, that is to say cases where the
siphon and the hole O are displaced and cases where they are not displaced. As
for other cases the solutions would he analogous.
It must be noted that I can without inconvenience vary the details. Thus
instead of a chain connecting the two levers, a cord may be employed or even a
little roller may be interposed to facilitate the movement of the chain or cord,
or the chain may be replaced by an arrangement of suitable levers. The rods B
and b instead of being rigid may be chains or cords or the like.
It is evident that the two discharges of water which I adopt prefembly may be
fixed or definite, or even variable or optional, or even one may be fixed and the

page_text: other variable. It is also evident that these two discharges instead of being
different may be equal and I reserve the right of employing two or more mechanisms
or arrangements of the same type or of different types allowing similar discharges.
In the latter case, as shown in Figure 22 of the accompanying drawing, the
reservoir is divided by means of a partition C into two equal compartments A
and B containing each four litres. These two compartments communicate at the
top above the partition which may have at the top one or two openings e. In
this case the action is as follows:-When it is only a question of washing away
liquid substances, either of the two handles may be pulled, thus delivering only
four litres of water for the flush. If on the contrary it is a question of removing
solid matters, both handles must be pulled either together or one after the other,
thus giving twice four litres, or in other words eight litres of water in all. The
partition C may be also arranged in such a way that the compartments A and B
contain unequal quantities, say, for instance, that A contains 6 litres of water
and B only two litres. In this case the chain b would be pulled for the small
discharge two litres and the chain A for the larger discharge 6 litres, or both
chains may be pulled either together or in succession in order to have the large
total discharge of 8 litres of water.
It will be seen therefore that this arrangement of reservoir separated into two
or more compartments offers certain peculiarities.
There need only be one ball tap to allow of the reservoir supplying all the
compartments, or there may be a separate tap for each compartment.
In all these cases, that is to say where the reservoirs have partitions or are
without partitions and whatever the internal arrangements may be, instead of
having several pull chains they may be connected and only a single one he
employed which hangs within the reach of the hand.
In order to render this idea clear in the case of my improved apparatus with
two discharges, the two chains may be connected as shown in Figure 23 for
instance. If it be desired to operate only a single discharge, the small one for
instance, the lower chain must be pulled and the handle pulled in the direction
of the arrow B. If it be desired only to operate the large discharge the handle
must be pulled in the direction of the arrow A. Finally if it he desired to
operate simultaneously the two chains the handle neel only be drawn lown
vertically that is to say in the direction of the arrow C. If the upper chains are
in danger of touching the reservoir, they may be held suitably apart by a cross
piece E or by any other suitable means.
The two chains might also be approached to one another as shown in Figure 24
in order to allow of their being easily drawn simultaneously as well as to allow
of their being drawn separately according to requirements.
With a reservoir having several discharges, if desired only a single pull chain
may be applied allowing the desired discharge to be obtained no longer by varying
the direction of the pull, but by varying the strength of this action, that is to say
by pulling the chain more or less always in the same direction, preferably vertically,
say by drawing it five centimetres in order to obtain the small discharge and
twelve centimetres in order to obtain the larger discharge. I will now describe
as examples several modes of construction allowing this idea to be obtained :--
1. Figure 25. X is the reservoir having several discharges (preferably two
as hereinbefore mentioned). The two chains A and B are connected at H at the
top of a rod T which passes through, a guide D and which is operated by a single
chain C and a single handle P. As the chain C hangs vertically and assuming
that the chain O which governs the larger discharge m is a little longer than the
chain B which operates the small discharge n, the result is that when at rest
the chain B B is always taut whilst the chain A is slack and is only stretched
when the top H of the rod T has descended for instance 5 centimetres. If the
handle P be pulled down only five centimetres and then be released, the small
flush is alone produced, but the large flush will not take place. If on the

page_text: contrary the handle P be continued to be pulled causing the rod T to descend
12 centimetros for instance the larger discharge takes place in its turn.
If the chains have a tendency to touch the reservoir, they may be kept away
from it at a suitable distance by rollers fixed to the reservoir or to the wall, or
even by a cross piece E marked in dotted lines in Figure 25, or even by any
other means.
2. Figure 20. X is the reservoir having two or more discharges, preferably
two. A single chain C attached to a single lever L is employed constructed in
such a way that the small discharge N commences to act as soon as the chain is
pulled. In this case however the lever is prolonged to the right by means of a
piece L' having a groove or slot R, the bottom F of which operates the larger
discharge M in such a way that the arrangement of this large discharge does not
commence to be set in action until the chain has been pulled at least five centi-
netres. If therefore the handle P le pulled down only five centimetres for
instance and then be let go the smaller discharge is alone produced and the larger
discharge does not take place. If on the contrary, the handle L continue to be
pulled and be caused to descend 12 centimetres, for instance, the larger discharge
uly takes place.
The groove or slot R may be open at the top as shown in full lines or may be
closed as shown in dotted lines. Finally, in order that the hand may be warned
when the first five centimetres have been traversed the handle, a catch, spring,
projection or the like which produces a little shock or sort of stoppage may be
arranged, but one which it is easy to pass beyond if it be desired to cause the
handle to descend 12 centimetres.
Figure 27 shows another modification in which instead of the grooved piece R
mentioned in Figure 26, the end I of the lever or arrangement for the large
discharge may be attached by an unstretched chain or any suitable connection
in such a way that the lever only commences to act on the arrangement on the
larger discharge M. when the handle P has already been pulled down more than
5 centimetres for instance.
It is evident that other combinations of chains, levers and the like may be
easily imagined and of divers arrangements for obtaining two or more different
discharges whether such discharges he separated or combined by single
mechanism. The same remark applies here as in the preceding case as regards
a little catch or projection arranged if desired in order to warn the hand when
the handle has passed the first 5 centimetres.
Different discharges may also be obtained by means of a single chain by
perforating the bell or siphon as shown in Figure 28 with a little hole O which
may be closed by a valve C fixed on the lever L. When the chain, which is not
shown in this case, is pulled the lever L rises in the direction of the arrow and
raises the bell. The hole O is thus opened, but at this moment that is of no
importance. Then the lever and the bell are allowed to fall back again, the
valve closes the hole O and the siphon commences to draw. If the matter was
left in that condition the reservoir would be entirely discharged, but if the lever
be caused to rise only a little in the vertical movement which it has in a ring T
so as to open the hole O without raising the bell the siphon action of the latter
ceases and the discharge of water is stopped.
A simple means is thus afforded of stopping the discharge of water when
desired. This arrangement is applicable to bell, siphon apparatus, sunk joints
or the like.
As regards the bells which may he employed in the arrangement of one or the
other discharge or even for both, the volume of the discharge may be sometimes
regulated by boring a suitable hole in the said bell such for instance as O in
Figure 29. This air hole serves to unprime the siphon when the water reaches
a given level, and the discharge of water is thus arrested, but this hole bored for
instance in the bell of the smaller discharge might perhaps a little diminish the

page_text: force of the flush of the larger discharge and even perhaps stop it. In order to
obviate this possible inconvenience, I replace the hole O by a siphon air hole U.
This is clearly secu in the two views of Figure 29 which ard respectively a
vertical section and plan view and which show how I arrange the air hole N with
its water seal.
It is immediately evident from this that after the working has been effected
and the desired amount of air has been admitted,, there is still a water joint or
seal which will consequently prevent any violent admission of air.
I may also remark that in the case of existing apparatuses or those already
planned in order to profit by my, invention the problem is in fact simple enough
as it is generally only a question of adding a little device enabling a. less
voluminous flush of water to be discharged for instance 2 litres; and consequently
a's almost always the apparatuses to be added are only placed a little, below the
level of the water, they have only to hear an almost insignificant pressure.
In all the solutions the two pull cords or chains and their handles may be
similar, but it will be evidently preferable to make them dissimilar, for instance,
to make the cord corresponding to the 8 litres flush shorter, so that it. will be
less easily grasped and pulled and its handle may also differ from the other. in
order to avoid their being mistaken.
The pipe and apparatus corresponding to the 2 litres flush may if desired be
of less section than the pipe and corresponding arrangement of the 8 litres flush,
but that presents no advantage but rather the contrary and they may be inserted
in separate cisterns connected by pipes instead of both in one cistern. The two
pipes (large and small flush) may only meet at the pan or basin of the closet, or
even before that, but in such a way then as not to hamper the working of either
of them or cause them to work.in an irregular manner, which may be prevented
by placing for instance on the large flush pipe or on both pipes, an enlargement
forming an air reservoir.
I reserve the right of varying the forms, dimensions, proportions and accessory
parts and employing for their construction any material which I may deem suitable,
and it is of course understood that the various mechanisms relating to either of
the two discharges may be combined and actuated by pull chains, cords or the
like, pneumatic balls, hydraulic valves, hydraulic or electric buttons or any other
suitable arrangement preferably different or having different appearances for the
two discharges, the said mechanisms being able to be arranged. with the view of
producing only a single discharge or if desired one discharge and then the other
to supplement. the first flush if it has been insufficient..
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. The improvements in flushing cisterns of water closets, which consist in
placing in the same flushing cistern or in several communicating flushing cisterns,
two or more mechanisms or arrangements of similar type or otherwise, allowing
of flushes of different quantities or volumes being discharged; the whole sub-
stantially as herein before described and shown as an example in the accompanying
drawings.
2. In apparatus of the kind described and as a means for stopping the action
of the siphon serving to produce the water flush, the use of an air-hole (with or
without a pipe) adapted to be opened or closed at will by means of an arrange-
ment of levers or other suitable mechanism thus allowing one or other of the
two discharges to be obtained; substantially as herein before described and shown
as an example in the accompanying drawings.
3. In apparatus of the kind described the use of a chain, cord, or the like or
a series of rods and levers for producing the connection between the two levers,
enabling the bell or the valve to be raised, in other words causing the siphon to

page_text: be started, substantially as hereinbefore described and shown as an example in
the accompanying drawings.
4. In apparatus of the kind described the use of a valve operated by a kind of
balancer, or even operated directly, for opening or closing the hole for causing
the siphon to cease action; substantially as hereinbefore described and shown as
an example in the accompanying drawings.
5. In apparatus of the kind described the use in the same flushing cistern or
several communicating cisterns, having separating partitions or otherwise, of two
or more mechanisms or arrangements of the same or different types allowing two
or more flushes to be obtained but more particularly two flushes of water, the
amounts of which are either both fixed or variable or one fixed and one variable
whether the quantities of water thus discharged be equal or unequal in volume;
substantially as hereinbefore described and shown in the accompanying drawings.
6. The use with a flushing cistern of two or more pull chains, but preferably
two, one or other of which is operated in order to obtain one or other of the
discharges of water as desired or even which are both operated together, whether
these means of operating are pull chains or cords, pneumatic balls, hydraulio
devices, electric buttons or any other arrangement either of the same nature or
different natures and having preferably in all cases a different appearance, the
said pull chains, cords or the like being united as desired to form a single pull
cord, chain or the like having a single handle thus enabling one or other of the
discharges to be effected, or even both simultaneously by only varying the
direction of the pull exerted on the handle, or (the said chains) being simply
arranged in proximity one to the other to allow of either of them being successively
pulled with equal facility or both of them simultaneously according to require-
ments the whole substantially as hereinbefore described and shown in the accom-
panying drawings.
7. The use with a flushing cistern of an arrangement of chains or analogous
means of operation which when at rest are unequally stretched, connected with
a single pull chain in such a way as to obtain successively several discharges
(preferably two) so that by pulling the handle a little, one discharge, (the smaller
one for instance) only is operated and by pulling the said handle more strongly
the other discharge is operated; substantially as hereinbefore described and shown
as an example in the accompanying drawings.
8. The use with a flushing cistern of a common lever (L) connected with an
arrangement allowing of a small discharge of water, and with another arrange-
ment allowing of a larger discharge in such a way that by pulling the handle slightly
the small discharge is obtained and by pulling the handle more strongly, the

produce the flushes of water, of a catch or projection or the like causing a slight
shock or stoppage to warn the hand in pulling the handle, but yet easily over-
come if it be desired to cause the latter to descend lower; substantially as herein-
before described.
10. In apparatus of the kind described the use with double or single discharges
of a system of pull with lever and handle allowing the desired water action to
be produced by pulling vertically, substantially as hereinbefore described and
shown as an example in the accompanying drawings.
11. In apparatus of the kind described the use of an air hole with water seal
for preventing any irregular admission of air after the desired action has been
produced; substantially as herein before described and shown as an example in
the accompanying drawings.
12. The application to the bell, siphon or the like of a flushing cistern, of a
valve serving to open or close a hole (causing the said bell, siphon, or the like, to
cease operation), the said valve being capable of being operated by means of a
