PERIODICALLY OPERATING FLUSHING INSTALLATION Filed Au 16, 1956 INVENTOR. Max Wagner g/Mx' PERIODICALLY OPERATING FLUSHING INSTALLATION Max Wagner, Bergstrasse 13, Grating Markt, Bavaria, Germany Filed Aug. 16, 1956, Ser. No. 604,546
2 Claims. (Cl. 137129) Sanitary periodically operating flushing installations for public lavatories and water closets, preferably with continuous water feed, are known, in which a float vessel incorporating a water discharge tube is connected up with the water discharge pipe of a flushing cistern by means of a hose. The objection to this arrangement is that the float is open and that an automatic initiation of the flushing is not easily possible with a flushing tank of ordinary dimensions. This type of flushing system is also open to the objection that it can only be emptied to the height of the lowermost edge of the open float, so that there is a dead space which is always filled with water.
Therefore it is proposed according to the invention to construct the float as a hollow body with a water inlet aperture arranged at about the highest point and to connect it with the movable discharge tube by a small tube or the like extending in the interior of the float to within a short distance of the bottom thereof, and to restrict the upward movement of the float with the discharge tube by an abutment.
By this means the flushing operation takes place absolutely automatically and its distance is determined by the quantity of water fed. Moreover the certain and reliable operation itself is ensured by feeding the water dropwise.
According to another feature of the invention, the connecting hose is constructed as an accordion tube in order to maintain the water buoyancy as constant as possible.
An embodiment of the invention is illustrated diagrammatically by way of example in the only figure of the accompanying drawing.
Water is continuously fed into the flushing cistern 3 by means of a supply pipe 2, the quantity of water being regulated by a cock 1. A water discharge pipe connected to the cistern by means of a screw joint outlet 11 extends through one of the side Walls of the flushing cistern and is connected to a movable discharge tube 5 by means of an accordion tube 4. The free end of the discharge tube 5, which is preferably bent, carries on its under side a cylindrical float 7 provided with water inlet apertures 8 at about its highest point. The interior of the cylinder is connected with the interior of the discharge tube 5 by means of a small branch tube 9 reaching almost to the bottom of the float. 12 are adjustable bracket or fixing screws for holding the flushing cistern.
The flushing cistern operates in the following manner:
The water fed through the regulating cock 1 and supply pipe 2 first fills the flushing cistern 3 up to the height fitates Patent 0 indicated by the dot-dash line 6. When the water has reached this height, the discharge tube 5 together with the float 7 comes into contact with the stop pin 10 owing to the buoyant action of the water and the flexible, special-section rubber sleeve 4. The water that continues to flow into the flushing cistern 3 rises further and finally passes through the bores or apertures 8 into the float 7. When the float is flooded it immediately causes the discharge tube to sink thereby releasing the flush which continues until the flushing tank is emptied right down to the bottom.
The small branch tube 9 at the same time empties the float by siphon action, whereupon the operation can commence afresh. The cross section of the tube 9 is chosen to be to the cross section of the accordion or discharge tube 4 as the volume of the float is to that of the cistern. Thus, it is made sure that the float will not be emptied before the cistern and that no air will enter the discharge tube prematurely and prevent the water in the cistern from being completely discharged at each flushing. The quantity of water fed and consequently the flushing duration can be determined as required by means of the regulating cock 1.
I claim:
1. In an automatically operating flushing device for water closets and the like, a tank having a bottom and a side wall, the side wall being provided with an outlet, a conduit to admit water to the tank, a conduit connected to said outlet and extending downwardly to a point below the bottom wall of said tank, a flexible pipe to discharge water from the tank, a float formed by a hollow body having apertures through its top wall portion and adapted to rise from a lowermost to an uppermost position when water is admitted to the tank, and to be fully filled with water through said apertures when the float is in said uppermost position and the water level rises to overflow said apertures, said discharge pipe having one end secured to asid outlet and the other end to the float, and being out of communication therewith, said other end being open and being located adjacent the bottom of the float whereby, with the float in its lowermost position, said open end is near said tank bottom, thus making sure that the body of water in the tank below the level of the outlet will be discharged whenever the float sinks to the lowermost position, a conduit branching off from the discharge pipe and entering the interior of the float to extend to the bottom thereof, and an abutment provided on the tank to stop the rising float in the uppermost position.
2. In the device according to claim 1, the float being cylindrical, with the axis of the cylinder extending horizontally, a portion of the discharge pipe at said other end encompassing a surface portion of the cylinder, that is remote from the point at which the discharge pipe is secured to said outlet.
