SPECIFICATION forming part of Letters Patent No. 396,318, dated January 15, 1889.

Application filed .Tune 13, 1888. Serial No. 277,001. (No model.)

To @ZZ whoml it may concern.-

Be it known that I, HARVEY R. YOLFE, a citizen of the United States, residing at Louisville, in the county of J efferson and State of Kentucky,`have invented certain new and useful Improvements in Vater-Motorsg and I do hereby declare the following' to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in water-motors having special reference to that class in which two concentric wheels are used. 1n most water-motors in which two wheels are used the water is carried after ithas done its work and become dead-weight, and the water is so used that sand and other impurities in it increase the wear of the machinery.

The object of my invention is to provide a motor in which wear and friction from impurities in the water and from carrying' deadweight are avoided, the pressure of the water utilized to reduce weight and friction on the bearings to the lninimum, and the quantity of the water used may be reduced without retarding the rate of liow. 1 accomplish these objects by the mechanism and arrangement of parts illustrated in the accompanying' drawings, in which` Figure 1 is a vertical sectional view of my motor. Fig. 2 is a top plan view of the wheels, showing their relation to each other. Fig. 3 is a vertical sectional view, on an enlarged scale, showing the hollow part ot the central spindle and its relation to the piston-head and conduit-pipes.

In my motor the two concentric wheels are horizontal, havingfor a common spindle the vertical shaft N, which is hollow in its lower 4o part. The lower wheel is on thc principle of the common turbine, receiving water f rom below, and thus relieving the lower bearing' from the weight of a standing column ot water, and discharging the water from the ends of theIcurved conduit-arms E. The upper wheel is constructed on the principle of an overshot wheel, except that the floats or blades A are bolted or riveted on the inside of the sole B instead of on the outside. These floats may be radial, curved, or angular. There is a done its work.

shrouding or circular plate, J, on the upper side of the wheel, butnone on the lower side. The sole B extends down far enough to cover the nozzles of the conduit-arms E of the lower wheel, and is bolted to wrought-iron arms C, which are inserted into the hub of the lower bev el-pinion, D. n

K is a hub on the shaft N, through which radial holes are made connecting with the hollow of the shaft, and into these holes the 6o cond uit-arms E ofthe lower wheel are inserted. The hub ot' the upper wheel revolves on and has a bearing on the hub K of the lower wheel.

1 is the casing' or frame for the motor, hav- 65 ing a top, I', removably secured to it. The floats A are raised a proper distance :from the casing 1 to allow a free discharge-way for the. water issuing from the arms C after it has The conduit-arms E are bent upward toward their ends, as at Y. All of the conduitarms E are provided with stop-cocks L, so that the water may be readily shut off from any of them through man-holes M in the top I of the casing, if it is desired to use less water.

X is a bracket with box to support the upper end oi' the spindle N, and is a set-screw operating on the head ot' N.

` G is a bevel-pinion held in place around N by a set-screw, g, through its hub.

H is a bevel-wheel engaging with the bevelpinions G and D, having a shaft, F, supported by brackets f and f with boxes. F is a pul- 8 5 ley for transmitting power.

V is a wing cast with the frame I, having a boss, O, on its inward end, which serves as a bearing for the hub K.

o is a water-inlet extending through the 9o wing and to the center of the motor under the spindle N, and then upward through the boss O. ln this part it is enlarged enough to admit the lower part of the spindle N.

S is a recess bored in the bottom of the wing under N, of sufficient diameter to admit a piston-head, P, keyed onto the lower end of N, or attached to it by a screw-thread. This piston-head is constructed with one or more expansive packing-rings, Q.

These 10o rings are expanded by the pressure of water passing through small openings R.

The recess-bore S is closed at bottom by a screw-plug, T, which can be removed when necessary to attach or detach the piston-head P, or to clean out any sediment deposited.

U is a circular case to carry the upper casing, I.

Arrows show the course of the water.

The operation of my invention, which will be readily understood in connection with the above description, is as follows: The water under pressure, flowing through the opening u and upward through the hollow part of the spindle N, passes into the curved conduitarms E, and, issuing from their ends, causes them to revolve rapidly in accordance with a \\'ell-known principle. The jet-s of water is suing from the ends of the arms E strike the lioats A and cause them to revolve in a direction opposite to that in which the turbine wheel moves.v 'lhe revolution of the wheels in opposite directions transmits a continuous motion to the shaft F through the bevel-pin ions D and G and the bevelfwhecl ll. The effect of bendingI the conduit-arms upward .is that the ,jets issuing will strike the shrouding J as well as the blades A, and tend to lift the wheel C and lessen the friction on the bearing K. The upward pressure of the water under the piston-head P tends to lift the weight of the shaft N and the two wheels from the bearing on O, which supports the whole, and thereby lessens the friction and wear at that point, which would otherwise be great. As the water as soon as it has struck the floats A falls freely 'out of the casing to the waste-outlet lV, there is no dead-weight of water to carry and no backlash to retard the action ofthe wheels as they are running in air. vThen less power is needed, the water can be shut off from any of the conduitarms by the cocks L, or by loosening the setscrew g, and lifting the pinion G till its leaves are disengaged, and then tightening the screw so as to hold the pinion disengaged, the turbine wheel is put out of gear and can be held stationary by tightening the set-screw 0c, operating on the head of N, when the shaft F will be turned by the revolution of the upper wheel alone through the pinion D and the wheel H.

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

l. In a water-motor having two concentric wheels, the combination, with the frame I, having the top I', of the bracket X, the setscrew the vertical shaft N, the boss O on the wing V, the bevel-pinion G, and the set-screw g, substantially as set forth, and for the purpose specified.

2. In a water-motor, the combination, with the case I, having a removable top, I', provided with holes M, and a wing, V, provided with a boss, O, of an inlet-opening, l@,through the wing V, a recess or bore, S, in the wing under the boss O, a screw-plug, T, a vertical shaft, N, hollow in its lower part, a pistonhead, l?, a turbine wheel having its conduitarms provided with stop-cocks L and inclined upward at their extremities, a modified overshot wheel having floats A and shrouding J, a bevel-pinion, D, a bevel-wheel, H, and a bevel-pinion, G, having a set-screw, g, substantially as set forth, and for the purpose specied.

In testimony whereof affix my signature in presence of two witnesses.
