This invention relates to actuating means for 23, and which is guided in the housing I5 (Fig. 1).
This housing is attached by means of bolts or the
Siphon-discharge apparatus with vertically mov
able siphon bell for delivering different quantities A like 2I to the back plate 20 which is secured for
of water at will (large and small flush).
Actuating means for Siphon-discharge appara
_tus with vertically movable Siphon bell are al
ready known which admit of delivering different
quantities of water at will (for large and small
flushing) by pulling down the conventional op
l()> erating handle to different levels.
In accordance with the present invention there
is employed for delivering one quantity of water
(large ñush) , in the usual manner, the actuating
means normally attached to the draw member
151 for lifting the siphon bell, and for delivering an
other quantity of water (small flush) a further
actuating means which is likewise connected with
the said draw member, and which is movably
supported in a fixed housing which at the same
2Q» time serves as a guide for the draw member. vIn
order to preclude the possibility of mistaking the
one actuating member for the other themanner
of operating these two members is arranged to be
different (e. g. in the one case by pulling and in
2,5. the other by pushing). To enable the lift of the
siphon bell to be adjusted as required, and that
example to a wall.
In a slot in the rod I4 there
engages the one arm of a bell-crank lever I9
5
which is pivoted at I8 in the housing I5, and of
which the other arm is articulated to a stem
extending out through the wall of the housing
and ñtted with a knob I'I.
To effect the large flush the rod I4 is pulled 10
down in the usual manner by means of the handle .
`23 so- as to lift the bell of the Siphon to such an
extent that >siphonic action is set up and the
entire contents of the tank become discharged.
To eñect the small flush the knob I1 is pressed l5
towards the housing, with the result that the rod
I4 is pulled down to a less extent than when
operated by means of the handle. The bell 9 of
the Siphon is then only slightly lifted, and water
flows from the tank only as long as the knob is 20
kept pressed in. When the knob or the handle is
released the rod I4 returns to its position of rest
in‘ response to the action of the spring 24. By
screwing the ring ll in the Sleeve I2 which is
attached to the rod I4 by means of the screw I3 25
the draw chain may if desired or necessary be
independently for the large flush and for the tightened up. The means provided for guiding
_small flush, parts of the actuating mechanism are the rod I4 also serve to guide the chain, and thus
made adjustable. Further features of the in , prevent the latter from becoming twisted.

The invention is illustrated, by way of example, the actuating knob I1 is of tubular shape and
screwed on to a thrust stem 25 articulated to- the

These screws are suitably countersunk, as a
precaution against unauthorized alteration of the
lift of the siphon bell and consequently of the
quantity of water discharged for the small flush.
In order to provide for adjustment of the lift of 45
the siphon bell for the large ilush also, the handle
23 is connected by means of the ring 22 to a
sleeve 2'I guided in the casing I5, this sleeve be

the rod I4 can be made to consist of two slidably
interengaging or telescoped parts, namely a

In the form of construction shown in Fig. 3
of the drawing there is` provided, instead of the
push-in knob and bell-crank lever, a handle 30
which is connected to the rod I4 (portion Illa)
and which is guided in a slot 3| in the housing I5.
In order to provide for adjustment of the stroke
of the projecting handle 30 there is screwed on
to the rod I4 a sleeve 32 which is guided in the
housing, and which in its turn is connected,
- _ through the intermediary of the ring II, to the
draw member for the siphon bell.
The device according to the invention has the
particular advantage that it can readily be oper
ated by anyone, while the Siphon-discharge ap
.paratus is saved from undue or unnecessary
strain, and the draw chain prevented from becom
ing twisted. Since the actuating device is sepa
rate from the ñushing apparatus proper it may be
fitted to existing flushing installations.
