In Fig. 1 a lever i2 is pivoted to the plate 8 at it. One arm lid of said lever 12 is forkshaped (Fig. 2) and carries a roller l4 adapted to cooperate with the hose 6 and to deform same against the support 1 thus closing the hose by a pinching action.

. -closingeend positi-omofrthe roller rl 4 may 40 be determined by a stop (not shown) or a design such that the roller I4 is clamped in an end position against the hose 6 and the support 1.
The speed of the automatic closing action de pends on the weight and proportions of lever I2 and the parts attached thereto.
When the handle I5 is raised to the position shown in dotted lines and then actuated the lever l2 with roller 54 during the closing period due to the heavier weight at the side of arm [2 so will fall down with heavier pressure and the hose 5 will be sooner closed. Thus a flushing with smaller quantities of water is obtained.
In Fig. 3 the entire mechanism and the bag 1 is enclosed in a casing 4.
The pivot l3 of lever I2 is arranged in a bracket 22 secured to the casing v4.
The arm 221 of lever 12 is connected to the shaft 23 of a press button 24 by means of a pin and slot connection 25, 25a.
The shaft 23 is guided in a sleeve 26 mounted in the casing i. The bottom part 4a of the casing is removable.
A spring 28 is attached at one end to arm i2a of lever 12 and at the other end to a lug 21 of bracket 9.
3D is a pipe for discharging liquid, which may have entered the casing 4.
In this embodiment the lever l2 with roller 14 is spring urged.
The spring mechanism may be so constructed that the effective load on the lever I2, 1. e., the momentum on said lever with respect to its pivot !3 may be varied.
This is shown in Fig. 4.
One end of the spring 28 is attached to a block 3|, which can be shifted in a slot am in arm I20;
of lever i2.
The ends of the shafts 23 and 23a of two buttons 24 and 24a are provided with slots 35 and 31 and connected by links 32 and 33 to the arms 35 and 34 respectively, of a shiftlever.
In the position of the mechanism shown in Fig. 4 on pressing button 24a link 33 swings lever arm 34 to the right and shifts block 3| also to the right. The spring 28 now has its highest tension and the roller closes hose 8 at high speed after actuation of lever i2, which happens in the later part of the inward stroke of button shaft 23a when the left hand end of the slot 31 in said shaft engages the pin 25 at lever arm I212.
" On pressing button 24 due to the fact that pin .25 at lever H2!) is already at the left end of slot 36 in button shaft 23, the lever I2 is immediately swung about its pivot [3 without a previous adjustment of the spring 28 which exerts the smallest momentum on lever arm l2a.
The closing period of roller 14 is greater and more water is discharged.
Having now described the nature of my invention and the objects thereof what I claim is:
1. An apparatus for flushing a toilet comprising: a closed tank having an inlet arranged "for connection with a Water pressure line and having an outlet, a discharge pipe, one end of said discharge pipe being connected to said outlet, the other end of said discharge pipe being arranged for connection with a toilet, at least a portion of said discharge pipe being made of elastic material, an abutment arranged adjacent said elastic portion or said discharge pipe, a movable pressure member arranged for cooperation with said elastic portion of said discharge pipe, bias- I ing means connected with said movable pressure member, said biasing means being operative to urge said movable pressure member normally against said elastic portion of said discharge pipe so as to close same by a pinching action in cooperation with said abutment, at least a portion of the walls of said closed tank being made of an elastic material so as to permit an expansion of said tank by Water entering same through said inlet, and setting means connected to said movable pressure member for moving same away from said discharge pipe against the action of said biasing means into a position wherein said pinching action iseliminated and the outlet of the tank is opened for a discharge of water from said tank under the action of pressure accumulated in such an expanded tank.
2. An apparatus for flushing a toilet comprising: a closed tank having an inlet arranged for connection with a water pressure line and having an outlet, a discharge pipe, one end of said discharge pipe being connected to said outlet, the other end of said discharge pipe being arranged for connection with a toilet, at least a portion of said discharge pipe being made of elastic material, an abutment arranged adjacent said elastic portion of said discharge pipe, a movable pressure member arranged for cooperation with said elastic portion of said discharge pipe, adjustable biasing means connected with said movable pressure member, said biasing means being operable to urge said pressure member normally against said elastic portion of said discharge pipe so as to close same by a pinching action in cooperation with said abutment, adjusting means associated with said biasing means for adjusting same, at least a portion of the walls of said closed tank being made of an elastic material so as to permit an expansion of said tank by water entering same through said inlet, and setting means connected to said movable pressure member for moving same away from said discharge pipe against the action of said biasing means into a position wherein said pinching action is eliminated and the outlet of the tank is opened for a discharge of water from said tank under the action of pressure accumulated in such an expanded tank.
