WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 349,856, dated September 28, 1886.

Application iiled May 12, 1886. Serial No. 201,935.

invention consists of a rotary water-wheel provided with buckets having inclined ends and semicircular cup-shaped rear parts,which are supported by the flanged rim of the wheel.

The invention consists, further, of an improved construction of the water-injection nozzle and valve, as will appear more fully hereinafter, and nally be pointed out in the claims.

In the accompanying drawings, Figure l represents a side elevation of my improved water-motor, parts being broken away to show injection-nozzle in section; and Fig. 2 is a vertical transverse section of the supply-regulat- .ing valve on line x w, Fig. l.l

Similar letters of reference indicate corresponding parts.

A in the drawings represents the shell or casing of my improved water-motor, which casing is made of cylindrical shape and supported on a suitable bed-plate, A. The lower part of the casing A is provided at one end with a supply-channel, a, and at the other end with a discharge-channel, b. At the interior of the casing is arranged a water-wheel, B, the shaft B of which is supported in eccentric bearings of the casing in such a manner that the wheel is closer to the supply-opening and farther from the discharge-opening,where by a narrower space is provided near the point where the water is injected, and a wider space at the opposite side of the casing where the water is dropped from the buckets and conveyed to the dischargechannel b. The supply-port a communicates by a channel, a,with a cylindrical casing, C', that surrounds the supply-regulating valve C. The valve C is arranged in an inclined position nearly tangential to the lower part of the water-wheel (No model.)

and seated in a cylindrical shell, C2, provided 5o.

with openings or ports d, that communicate with the exterior casing, C. The valve C is also provided with radial arms I, having slots or openings and enlarged T-shaped heads b', which latter open or close the ports d of the shell C2, so as to regulate thereby the supply of water to the interior of the valve. The valve C is provided with a hollow shank, d2, that is extended through a stuffing-box of the casing C to the outside, and provided with a 6o handle by which the supply-regulating valve C can be turned on its axis either by hand or by a suitable governor, so as to supply a greater or smaller quantity of water.

Through the hollow shank d2 of the regulat- 65 ing-valve C passes a needle-valve, D, which extends by its tapering inner end into the injection-nozzle D of the casing A. The shank of the needle-valve D is pivoted at its outer end to a fulcrumed lover, D2, that may be ad- 7o justed to different positions by means of an arc shaped perforated guide piece, f, and clamp-screwf, as shown in Fig. l of the drawings. The upper end of the lever D2 may be connected,when the motor is used for working 7 5 an organ-bellows, by a cord to the feeders of the bellows and automatically operated by the same, so as to set the needle-valve. The shank of the needle-Valve passes also through a stuffing-box at the end of the hollow shank of the 8o supply-regulating valve, so as to prevent leakage of water. The inner end of the needlevalve E is made hollow and provided with openings or ports e, that communicate with an annular pressure-equalizing chamber, C3, located between the casing of the supply-regulating valve C and the injection-nozzle D, so that the water is injected in two jets into the buckets of the water-wheel B, one jet being forced through the hollow nozzle of the needle- 9o valve and the second exterior jet through the injection-nozzle D. This has the advantage that the force of water on the buckets of the water-wheel can be varied, as either the injection-nozzle D may be entirely closed by the needle-valve and the motor run by the smaller jet supplied by the needle-valve or the needle-valve may be drawn back and the motor worked by the combined jets of the injectionnozzle and needle-valve.

The Water-wheel is constructed with sheetlnetal buckets'g, that are soldered or other- Wise attached to the ring -shaped parallel anges of the rim, each bucket being made of a straight part, g', and a curved or semicircular rear part, g2, which serves as a cup to receive the water and deflect the same and shed it when below the line of the jet that drives or propels the water-Wheel. The seniicircular part of one bucket rests on the straight part of the next bucket, as shown in the drawings, the buckets forming a simple and efficient Waterwheel, which readily sheds the water as the Wheel rotates, and which utilizes advantageously the full force ofthe water, as the buckets prevent the recoil of the water, so as to break or weaken the jet.

Having thus describedrny invention, I claim as new and desire to secure by Letters Patentizing-chamber and injection-nozzle, a needle- `valve located in the regulating-valve and provided with a hollow slotted nozzle, whereby an exterior and an interior jet are supplied to the water-Wheel, substantially as set forth.

2. A Water-,Wheel having a rim 4formed of ring-shaped flanges and buckets formed of straight and inclined front parts and semicircular rear parts projecting back of the plane of the front parts and resting upon the straightV Water so as not to interfere with the jet, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
