ROTARY NOZZLEHHEAD FOR WATER-MOTORS.

SPECIFICATION forming part of Letters Patent No. 380.691, dated April 10, 1888.

Application filed December 22, 1886. Serial No. 222,245. (No model.)

To all whom it may concern:

Be it known that I, EDWIN S. PIPER, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Rotary Nozzie-Heads for WatenMotors; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in nozzle-heads for water-motors, the object being to produce a head carrying several nozzles, each of different size, adapted to relieve the rotating nozzle-frame from the pressure of the water and to compensate for wear, and combining simplicity and cheapness of construction with durability and general eft'lciency in use.

With these ends in view my invention consists in a nozzle-head .having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a view in perspective of a nozzle-head em bodying my invention, together with a portion of a water-wheel. Fig. 2 is a view of the head in front elevation, and Fig. 3 is a view of it in central longitudinal section.

As herein shown, the forward end of the water'supply pipe A is provided with a bearing consisting of a frustoconical cap, B, having :its tapering face or side and flat end ground to form a bearing-surface, and provided in its tapering face and upon its under side with a discharge-port, C, of forward pitch.

The frame D is provided with a circularl series of wings, E, inclined outwardly from its rear to its forward end, and respectively having inclined water-passages F, conforming in inclination to the pitch of the discharge-port, with which their inner ends are brought into alignment by the rotation of the frame.

Nozzles G, each of different size, are located in the respective wings and form extensions of their water-passages. A central opening or recess, H, extending forward into the frame from the rear face thereof, adapts it to fit over the bearing or cap upon which it rotates, the

walls of such opening or recess being ground to form a close joint between the two surfaces.

A pivot, I, located in the center of the frame and entering the center of the flat end 'of the cap, secures the frame to the said cap. All wear between such frame and cap is compensated for by readjusting the said pivot, which consists of a screw left unthreaded where pass ing through the frame.

The rear edge of the frame is provided with a slot, J, for and located in line with each wing, such slots receiving a spring-actuated pawl, K, pivoted to the cap and holding the frame in its several positions of adjustment upon the bearing.

A yoke, L, secured to the forward end of the frame, carries a spindle, M, having an operatingwheel, N, by which the frame is rotated, secured to its outer end. Y

The described head is located close to the water-wheel O, which receives the water direct from the nozzles.

In using my improvement the frame is rotated to bring the waterpassage of a large or small nozzle into alignment with the dischargeport, according to the power required and to, the pressure or head of the water. In this way the amount ot'water consumed is made to depend upon the power required with obvious economy.

Under my invention the frame is relieved of the pressure of the water, wear is reduced to the minimum, and leakage avoided. Fur- Vthermore, without breaking the water, it gives it advantageous direction upon the wheel.

I would have it understood that I do not limit myself to the exact construction and combination ot' parts herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I am aware that a nozzle -head having a frame carrying a series of parallel cylindrical nozzles each of different discharging capacity and adapted to be rotated to bring them into alignment with a single aperture communicating with a water-supply is not new. I am also aware that a head having a series of cylindrical tangential waterpassages and a discharge-port for each is not new, and that it IOO is old to centrally pivot a conical cap having discharge-openings. I do not, therefore, broadly claim any of these constructions, but only the particular construction shown and described herein.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a nozzle-head for water-motors, the combination, with a hollow conical bearing having its larger end open and adapted to be secured to a water-supply pipe, its smaller end closed to form a ilat bearing-face, and a discharge-port of forward pitch in its side, of a rotary frame coned out to t over such conical bearing and the iiat face thereof and ad.-
