Be it known that I, G O RENNER, a citi- 'zen of the'German Republic, and residentof 137 Bilker Allee,Dusseldorf, Germany, have invented certain new and useful Improvements in Flush-Gisterns for which I havefiled applications in Germany, Mar. 8, 1914;

Austria, June 17, 1918; Norway, June 4,

1919; Sweden, June 5, 1919; France, June 7 1919 Switzerland, July 19, 1919 Finland, July 21, 1919; Belgium, July 31, 1919; Gr. Britain, Nov. 7, 1919; Italy, May 10, 1920; Luxemburg, Aug. 4, 1920; Holland, Sept. 15, 1920; Czechoslovakia, Apr. 23, 1921, of which the following is a statement.

The present invention relates to a flushing cistern, which, when not 1n use, is free of water, and on which the lock for the lever controlling the supply and discharge valves is released by a float. The feature of the present invention consists in the dischargeaccording to the present invention is shown in longitudinal section in Figures 1 and 5, respectively, while Fig. 2 is a plan of a portion of the tank. Fig. 3 illustrates the supply valve with a piece of the control lever and of the float lever, partly in section, partly in elevation; Fig. 4 is a plan to Fig. 3, Fig. 6 is the lock member incombination with the float lever and the control lever in side elevation in another position, and Fig. 7 is a front elevation thereof; Fig. 8 is a plan of the locking member with only a piece of the float lever.

The discharge valve hasthe form of a siphon tube 01. It is provided with trunnions e which rest in bearings t!) provided on the discharge tubea of the cistern tank I). When in an upright position this siphon tube bears with its jointing surface a tightly against 7 the mouthof the discharge tube a. Cast in one piece with said siphon tube (2 is a bracket 7, on which rests the control lever g.

This control lever g is pivotally fitted on a pivot on the housing 2' of the supply valve and engages with an arm 1 projecting there from into a slot 977} in the valve plug m, to which is fitted a rubber disk m for closing the supply orifice a.

The parttp of the floatlever g has slipped I i the supply orifice i isclosed ofl' thenose n, 7 and the counterpoise u on the control lever is in its lowest position (Fig.5) When as by a down, the control lever g, the; float lever and the part p are lifted until the latter same time the valve plugm is pushed back by the arm Z and the supply orifice i is opened. Theoflset h ofthe control lever g;

allows of the siphon tubefd is closed. "(Fig.1). As the supply valve is open, water will flowthrough'orifice t into the cistern tank 6. As it rises therein the water will lift the float ball 7 part p until it slips with its corner p from w belng moved into" I a vertical position so that the discharge tube andf thereby move the float lever and the thereto attached a nose 7%, so. that part 39 and with itcontrol .-'1ever.g lose their support and sink down.-

In testimony whereof I affix my signature;
