CURRENT WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 532,595, dated January 15, 1 895.

Application filed December 27,1893. Serial No. 494.863. (N0 model.)

To all whom it may concern:

Be it known that we, JOHN W. SEIVERT anLJAMEs WELCOME YOUNG, citizens of the United States, residing at MedicalLake, in the county of Spokane and State of Washington, haveinventedcertain newandusefullmprovements in Current Water-Wheels; and we do declare the following to be a full, clear, and exact description oftheinvention,such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to that class of current wheels or motors in which there is provided some means, as a funnel-shaped device, for conducting the water to the wheel.

It has for its objects among others to provide an improved wheel by which we can obtain greater power with less expenditure of force and at less expense than heretofore, and by suspending the same from boats we are en abled to navigate the same from place to place when desired. Further by having the wheel suspended or supported from and between boats instead of upon a frame or other support or structure fast upon the shore the wheel will always" remain the same distance below the surface of the Water, the boats risingand falling with the water as will be readily understood. We provide the wheel with a funnel-shaped device within which a portion, about one half, of the wheel is incased, the remaining portion, that down stream, being out of the casing so that the water may more easily escape after it has served its purpose in acting upon the wheel.

In the drawings Figure 1 is a view showing the wheel suspended from the boats in position for operation. Fig. 2 is avertical longitudinal section through the wheel and its funnel the blades of the wheel being shown in dotted lines.

Like letters of reference indicate like parts in both of the views.

Referring now to the details of the drawings by letter, A designates a boat and B another, both of which may be of anysuitable char- 5o actor and provided with meansfor anchoring them in the desired position. Supported from and between these boats in any suitable manner is the horizontal shaft 0 which isjournaledinthe lower ends of the supports D and upon this shaft are the adjusting nuts a as shown.

D'is a hollow shaft keyed upon the shaft 0 and upon which are the spiral wings or blades F which are of peculiar shape and form, being such as to best operate to produce the best results. These spirals or wings or blades can be made any desired size and pitch to give the required power. We may make some provisions for adjusting them upon their shaft.

The wheel is arranged in the water with its funnel-end up or toward the current and this funnel G is secured to a casing H which may be a cylinderor skeleton casing as shown, the funnelbeing of any desired material and proportions. The spirals extend the full length of the shaft and the shaft 0 extends beyond the same so as to be connected with the supports D, and the funnel extends but about one half the length of the blades as shown so while the front end is incased within the funnel the flaring portion of which serves to conduct the water to the wheel, the rear end, as it were, of the wheel is out of the casing so that as the water acts upon the spirals and after it has exerted its force thereupon it can freely escape and thus get out of the way so as not to be a dead weight thereon.

K is a band connecting the rear ends of the blades, it havingthe same diameter as the casing or cylinder H.

The funnel is designed to remain stationary while the flukes or blades revolve.

C is a sprocket wheel keyed to the end of the shaft 0.

The power may be transmitted in any suitable manner. It is designed to arrange the parts so as to drive or operate pumps for conveying water from a stream wherever the wheel is located to uplands for irrigating pur- ICO of the parts may be used in connection with other parts differently constructed and arranged from what they are here shown. The casing may extend a greater or less distance than whatit is here shown,but webelieve that about half way will be found preferable.

By connecting and supporting the wheel from boats the same can be quickly and easily moved from place to place when desired.

We reserve the right to vary theconstruction and arrangement of parts hereinbefore described as may be found necessary to produce the desired results in the best manner.

While we have described the apparatus as adapted for use for irrigating purposes, it is at once evident that it is equally well adapted for other purposes.

We claim- In a rotary hydraulic motor, the combination of the rods D, D, supported from a float and carrying at their lower extremities jour nal boxes in which turn a shaft 0 to which is keyed a cylinder D having the wings F,0 the cylinder H with funnel portion G, the said cylindrical portion extending over only a portion of the said blades for the purpose set forth, and the band K connecting the rear tips of the blades F, all substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.

JOHN W. SEIVERT. JAMES WELCOME YOUNG.
