Application filed .Tuly 11, 1910. Serial No. 571,454.

To all whom t may concern.'

Be it known that I, MARTIN SoHIcHTL, a citizen of the United States, residing at North Yakima, in the county of Yakima and State of Vashington, have invented a new and useful Water-Elevator, of which the following is a specification.

This invention relates to water elevating devices which are operated by the current in the course of the water; and itl is the object of the invention to providea water elevator of this kind which is simple in construction, and highly efficient in operation, a novel form of current wheel being provided, said wheel having buckets or scoops which empty into a hollow shaft supporting the wheel. f

The invention is illustrated in the accompanying drawing, in which- Figure l is a vertical section of the device. Fig. 2 is a transverse section of the wheel taken on the line 2-2 of Fig; 1. Fig.

- 3 is a cross section on the line 3 3 of Fig. 1.

Fig. 4 is an end view, partlybroken away, of a slightly modified form of wheel.

In the drawing, 5 denotes a tubular shaft which is held stationary, in horizontal position, in suitable supports 6. The shaft extends across the ditch, creek or other body of water, the supports being located on opposite sides thereof. The current of, the water in the ditch is utilized to drive` the elevator, the latter comprising a wheel having buckets or scoops which empty into the shaft through an opening 7 in the top por- Ytion thereof.

The wheel comprises two circular disks 8 which are suitably spaced, and between which are mounted buckets or scoops composed of radially extending blades 9, which fit between the disks, and have outstanding flanges at their outer yand sideedges. The flanges 10 at the side edges of the blades are fastened to the inner faces of the disks 8 in any suitable manner, and the flanges 11 at the outer ends of the blades coincide with the peripheries of the disks. The flanges 11 are of such a length, as to retain just a suflicient quantity of water, so that the depth of the dip of the blades within the propelling stream, will overcome the combined weight of the water in the respective chutes being lifted from the stream to the highest point of ejection, said flanges being at substantially right angles to the body of the blade, thus gripping the water and Patentednpr. 2, 1912. i

only retaining the water in the pocket l formed from the upper edge of the flange and vat an angle of 90o therefrom to the body of the blade or chute. This feature is of the utmost importance, as it renders the device operative with a stream of the` least propulsive force possible. The opening 7 is located between the disks. The shaft 5 passes centrally through the disks 8, and

the inner ends of the yblades 9 extend in close proximity to the surface of the said v shaft, as shown in Fig. 1.

To the outer faces of the disks yare secured hubs 12 which support the wheel for rotation on the shaft 5, said hubs being provided with anti-friction rollers 13, so that the wheel may run with the greatest ease.

`In operation, the wheel is rotated on the shaft by the impact of the current against the back of the blades 9. One bucket after the other dips into the water, and is elevated as the wheel rotates, and when the buckets come in alinement with the opening 7 the water is discharged from said buckets, through said opening into the shaft 5. A pipe (not shown) may be connected to the shaft to carry the water to the place of use.

Fig. 4 shows a slightly modified form of wheel in which the end disks 8 are dispensed with, the wheel being of skeleton form, and comprising radially arranged buckets 14 constructed in the same manner as the buckets of the first described wheel. The hubs 15 are secured to the end anges of the buckets, and the buckets are connected at their outer ends by rings 16, said rings being located at the opposite sides of the wheel. This wheel operates in the same manner as the one first described.

What is claimed is:

1. A water elevator, comprising a fixed tubular approximately horizontally disposed shaft having in the upper side thereof an opening, a wheel journaled upon said shaft, chutes carried by the wheel and extending radially from the rim thereof to the shaft, the forward side of each chute being unobstructed, said chutes being of uniform transverse dimensions throughout their length whereby they may serve as unobybottoms in planes coincidence with the radii of the wheel and the aXis of the shaft, the outer ends of said chutes being provided with a rim at right angles to the body of the chute and of such a height as to carry water from the receiving level to the ejeeting level in proportion to the propulsive force exerted to rotate the elevator.

2. A water elevator, comprising a wheel, a horizontally disposed tubular shaft having one end closed and the other` open, said shaft being provided with a slot in the upper portion thereof within the wheel, a series of radially disposed Water carrying chutes carried by the Wheel and extending from the periphery thereof to the center of the wheel, the bottom of said chute being an exact radius of the circle of the wheel, the forward side of' each of said chutes being unobstructed7 and a rim at right angles to and at the extreme end of each chute,pro viding a pocket for the reception of water the full width of the chute, whereby the quantity of wat-er engaged thereby will be liinited to the height of the rim.

In testimony that I claim the foregoing as iny own, I have hereto ahxed iny signature in the presence of two witnesses.
