Application filed September 18, m5. Serial No. 278,851.
To all whom it may concern: l Be it known that I, GE RG F. DE WEIN, a J citizen of the United States, residing at Milwaukee, in the, county of Milwaukee and State ofW'isconsin, have invented certain new and useful. Im rovements in Water? Wheel Nozzles, ofw ich the following is a specification;
This invention relates to certain improvej ments in nozzles, and more particularly to a nozzle which is pressure-balanced; that is, where there is no reactive :fcrce tending to swing the nozzle. The nozzle is also mounted so that the reactions on the two pivot pins 0 carrying the'nozzle aree'qual, This nozzle has great value whennsed with water wheels driven by greatheads, thus re? sulting very' high pressures. -When "so used it is desirable to lcontrol the outlet, as

This lattcrcontrolmay-he a hydraulic relay governor,andwhen so connected upthe swingingiis automatic'.

Fig;.--2 is a detail in horizontal pivot in moimtirig.v Fig. is a vertical section oft enozzle, i he water wheel 1- has'the stream of, water dlreotedagzinst it bythe two-part nozzle 2, 3. The nozzle-part 3has bolted to ltbearing ring 4 1 wh ch pivot pins 5 project. 3 The ivot 4 pins are mounted infthe ears JGfWlliC are olted .to projecting. lugs 61 cast integral with or bolted to th'elend of the penstock 62,

The discharge is controlled by the core 8 which has a point entering the ischargc. At its rear end this core passes throu h an opening in the wall of the nozzle, whic 1' opening, is between the ,two' curved-passages of the nozzle.
