-J r.-, a citizen of the United States, residingin the city and county ofSan Francisco, State of California,'hav e invented certain new and useful Improvements in StreaImDeflectors';

full, clear, and exact description of t e same: Inconnection with nozzles for directing an impact stream onto the'buckets' of a tangent'a water wheel or hydraulic motors it is ans tomary to employ what is termed a deflec-' tor for the purpose of deflecting. a portion 'ofthe impact stream off of the motor, such deflection being in accordance with-load a-v riations of the motor,1 tha't isto say, where the motors'load is reduced, the deflector out" into the issuing impact stream and deflect such a quantity of'the said stream as to leave,

only such a I 1 motor as will suflice for the required working load. With the deflectors or the common type, avery heavy efl'prt is required tokeep ortion thereof to bearonto the the deflector, when it starts to cut into the stream,f'r0m unbalanced force tending to pull the same therem. It follows,-thatby the use of such a defiector'forregulating the speed or power output of a hydraulic motor, as for instance.

a water wheel, that means must be provided which will hold the deflector in every and any position, hencea' heavy and constant load oei'ng thus placed onto the holding means,

usually the governor-for the motor, when the motor is in operation, in someinstances this load reachingmany thosuands of pounds, requiring the introduction ofvery expensive control-ling mechanism, making it difficult to handle sucha deflector byhandpower, if

for any'reason the controlling mechanism is outvof commission.

The objectof the )resent'mvention'is to provide astreaffirle ector for Water Wheels or hydraulic motors of largepower, which may be controlled by less complicated and cheaper means than at present required t;

operate and hold the same against the pres- J sure exerted thereon, or which may be con? trolled byhand power, if-for any reason the operating mechanism be thrown out of-commission, the deflector for attaining such object being so shaped as to utilize the reactory pressure of the water on the surface thereof to counterbalance the water. pressure which tends to force the same intothe stream.

5. A deflector attachment for hydraulic nozzles having a receiving portion, and a (llS- charge portion, the discharge portion being arranged in opposition to the receiving portion. I

6. The combination with a hydraulic nozzle of a cut-off or deflector connected to the nozzle and arranged to deflect a portion of 'the stream issuing from the nozzle, and a counteracting discharge portion on said de- "flector.

7. The combination with a nozzle of a plate for deflecting a portion of the stream issuing therefrom, said plate having a receiving surface and a balancing surface constructed and arranged so that the pressure of the water on the latter tends to neutralize the pressure on the former.
