FLOAT-VALVE.

To all whom it may concern:

Be it known that I, Fnnimncrr GEORG WANenLIN, engineer, a subject of the King of Saxony, and resident of 73 Holbeinstrasse, Dresden, Kingdom of Saxony, German Empire, have invented a new and useful Improvement in Float-Valves, of which the following is a specification.

rlhis invention relates to valve-casings such as are commonly employed for water supply pipes in water tanks from which water is siphoned for flushing closets.

One of the objects of the invention is to provide novel means by which the position of the valve with relation to its lever is fixed and insured.

A further object is to arrange outlet-channels between the valve and its inclosing casing in such a manner that the water issuing from such outlet-channels passes clear of the valve-lever. For these purposes the valve is of square shaped section and provided with four guiding edges, whereas the lever for operating the valve is of roof-like or triangular section. Said lever is passed along 1n a curve below the valve in such a manner that the lower ends or openings of the outlet-channels formed between the inner wall of the valve-casing and the outer surface of the valve are situated entirely free, thus the issuing flush-water may be discharged without splashing and without coming in contact with the valve-lever.

A further object of the present invention is to cast the valve casing as a whole in the shape of a pipe and to manufacture the valve in a similarly easy way by removing parts of its outer surface to form the four supply-passages situated between the valve and inner wall of the valve-casing. Thus there are nowhere sharp edges within the valve-casing and on the valve itself so that any splashing of the flush -water is prevented.

A convenient and desirable construction in which my invention may be embodied is Specification of Letters Patent.

providedv with a valve-casing forming the object vof the present invention.

a is a cross-bar provided within the top part of the flushtank or vessel z' and receiv ing from below a valve-casing b, the bottom flange of which is provided with elongated parts c for fastening the valve-casing o to the cross-bar a within the flush-tank z' and also with a projection carrying on its lower surface the eyes CZ between which the valvelever e is inserted and supported by a pin in a well known manner.

f is the valve-seat adapted to be screwed into a horizontal partition provided within the valve-casing Z), and g the valve loosely inserted from below into the casing Z) and being of the sectional shape shown in Fig. 3. ln consequence of the square shape of the valve g it is only guided by means of its four narrow edges arranged diagonally opposite each other in pairs whereas the re vmaining outer surface of the valve is formed in such a manner that between each of the two narrow guiding edges a smooth broad surface is obtained which together with the inner wall of the casing ZJ provides for a segment-shaped outlet-channel through which the flush water will issue.

Into the top recessed end of the valve g there is inserted a plug 71, of india rubber or the like, which on lifting the valve g will cont-act with or close up against the ringshaped valve-seat The bottom part of the valve g is in the manner of a screw-head provided with a broad notch g for receiving a tongue-like nose 72 projecting from the top rim of the valve-lever e, being of triangular o-r roof-like shape, as clearly seen by Fig. 4.

The flush-tank provided with the valvecasing forming the object of the present invention is shown in Fig. 5. In the center of the tank or vessel z' but in rear of its longitudinal axis is situated the bell-shaped cover Z suspended in a well known manner from a lever m and surrounding the iuslrpipe n the passage-section of which gradually inlll@ cover Z and the valve-casing b, and the third one lying toward the left hand side on the drawing serves as a chamber for retaining a considerable portion of any dirt or undesired foreign matter contained in the ushwater. For this purpose the low partition wall g d'oes not reach from the front wall to the back wall of the flush-tank z', but leaves an opening near one of the walls for allowing the flush-water together with its undesired foreign matter to ent-er the small compartment.

The valve-lever e carries at one end the bell or float r and at the other end a weight s. The compartment on the right-hand side formed by means of the partition-wall p for receiving the float. 1" is connected by means of a Siphon-pipe t in a well known manner with the flush-pipe n.

The operation of the valve-casing and the flush-tank described above is as follows: When the compartments are filled by the water issuing from the valve-casing Z) said water will rise in the middle and left hand side compartments and overflow the partition p thus filling also the right hand compartment. By raising the level within such compartment the float 1 is raised and a pull is exercised by the weight s on the lefthand end of the lever e, whereby the valve g together with its plug L is pressed against the valve-seat f by the nose or projection and the passage of water through the valve-casing b is stopped. Vhen it is desired to start the siphon-action the left hand end of the lever m is moved in a downward direction, the bell shaped cover Z is moved in an upward direction and the water contained within the right hand compartment is removed by sucking-action within the siphonpipe t, so that the level in said compartment is lowered and the float 11 will move in a downward direction. In this manner, a pull is exercised on the right-hand end of the lever e, its nose or projection 7c moving away from the valve g which thus is, by means of the water pressure existing above it and within the upper part of the valve-casing forced off the valve-seat, f so that the flushwater can enter the lower part of the valvecasing and pass through and issue from the same in a downward direction. The lever c is provided with a curved part which passes below the valve g and with a U-shaped part, to permit the downward movement of the right hand part of the valve-lever e wit-hout interruption by the upper edge of the partition p. Vhen the plug h of the valve g has left its seat, the lower openings of the four segment-shaped outlet-channels within the valve-casing are entirely opened and the water does not escape from the valve-casing b in a full jet but in four-single thin jets. By curving the lever the water is enabled to emanate clear of the lever and the latter will in no way be in contact with the water-jet, so that a splashing of the flushwater is entirely prevented.

What I claim is:

l. In a valve casing for flush tanks, the combination with a valve of square section provided with guiding edges and a broad surface between edges for forming thin water jets, ofra valve lever of triangular section and means for insuring and maintaining the position of the valve with relation to the valve lever, substantially as described and specified.

2. In a valve-casing for flush tanks the combination with a valve of square section and provided with four guiding edges and a broad surface between successive edges for forming four t-hin water jets, of a valvelever of triangular section and ofmeans for insuring and maintaining the position of the valve with relation to the valve-lever, substantially as described and specified.

3. In a valve casing for flush tanks, the combination with a valve of square section, provided with four guiding edges and a broad surface between successive edges for forming four thin water jets, the said valve having a notch in its bottom end, of a valve controlling lever of triangular section, the said valve controlling lever being provided with a projection in position to enter the notch at the bottom end of the valve, substantially as described and specified.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this thirteenth day of November 1909.
