POWER-WHEEL.

Specification of Letters Patent.

Patented May 13,1913.

Application filed April 5, 1912. Serial N 0. 688,786.

To all whom it may concern:

Be it known that I, HENRY E. OSBORNE, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Power-Wheels, of which the following is a specification.

The purpose of my invention is to provide a water wheel by which the full power'of a stream of running water may be developed and applied to the running of machinery, and one by the use of which the fish in said stream may be kept from passing up or down the stream and one that will not become clogged by the moss, leaves or other debris in the water. These objects I accomplish with the device illustrated in the accompanying drawings in which similar letters of reference indicate like parts throughout the several figures and as described in the specification forming a part of this application. I

Figure 1 is an elevation, parts shown in section on line as m of Fig. 2 and parts cut away. Fig. 2 is a transverse section on line y y of Fig. 1.

My device is mounted in a casing 1 made of metal or concrete within which is secured or formed integral therewith the annular inwardly extended flanges 2. A shaft 3 is horizontally mounted in the bearings 30 and carries thereon the power wheel B, and on the end thereof a pulley 4:. Keyed on said shaft 3 by the key 5 is the hub 6, extending from one disk to the other, having radially extended spokes 7. Secured on each end of said hub 6 is a disk 18, and secured to the bearings 9 on said shaft 3 is a drum screen A. Within said drum screen A and carried on the shaft 3 is the power wheel B. Said wheel B consists of a plurality of feathering blades 12, pivotally swung between said disks 18 by having their hinge rods 19 fitted within sockets 10 provided in said disks 18.

Each of said blades 12 is of sufficient width that the free edge thereof will contact with one of said spokes 7 and prevent said blade assuming other than a radial position in one direction, and lugs 31 are inwardly extended from said disks 18 against which the said blade strikes to limit the swing in the other direction. Also pivotally hung between said disks 18 and concentric with said feathering blades 12 are the vanes 13. Each is a double curve in transverse crosssection, and is pivotally mounted on a rod 2 1. The ends of said rods 24 seat in recesses 25 within said disks 18. The inner portion of each of said vanes is made in suilicient width that it will contact with the outer edge of the adjacent feathering blade 12. Said engagement of the shorter side of said vanes on the said blades provides a limit to the movement of said vanes on their pivots in one direction and inwardly extending lugs 32 are provided in said disks 18 against which the narrower edge of said vanes contact to limit the movement of said vanes in the other direction. When the free ends of the feathering blades 12 are in engagement with the spokes 7 and the passage of water is below the hub 6 and in an undershot direction, the narrower side of said vanes 13 will contact with the outer edge of the adjacent feather-- ing blade 12 and the water will be impeded and power developed on the wheel from the under-shot currents. Both the blades 12 and the vanes 13 will feather when in contact with the water over the hub 6, in the upper portion of the wheel. The pivoting of the said blades 12 and the vanes 13 will allow free passage of all the water that flows over the hub. Said drum screen A consists of two disks 1 1-, on the outer side of each of which is fastened the annular gear 15 within which is operated the gear 16 and the pinion 17. The inner peripheric face of said annular gear 15 has cogs or teeth 8. The said teeth 8 of said annular gear mesh with the teeth of the pinion 17, and its teeth in turn mesh with the teeth of the gear 16. The gear 16 is keyed on and turns with the said shaft 3. The said disks 1 1 turn in the opposite direction to the said shaft and are revolubly mounted on said shaft by the bearings 9. Pivotally mounted on the hinge rods 21 between the said disks 1 1 are the outer feathering blades 20, said hinge rods 21 seating in recesses or holes 22 in said disks 14L. Horizontally mounted between said disks 14: are the brace rods 33, each having the ends thereof secured in said disks. Inelosing said rods 33 and secured to the peripheric side of disks 14 is a coarse mesh screen 34. In

wardly extending from each of said disks 14 are the lugs 23 provided therein to stop the blades 20 from assuming other than a radial position in one direction on their pivots. The wheel portion B of my device which consists of the spokes 7, feathering blades 12 and vanes 13, is securely keyed on said shaft 3 and turns in the direct-ion of the arrow or, while the drum screen A mounted on the same shaft in the bearings 9, consisting of the disks 14, blades 20 and screen 3 1, turns in the direction of the arrow 7).

The direction of the main current of water is indicated by the arrows 0. The flow of the water will be impeded and confined by the blades 12 and vanes 13 and the disks 18, and the power of the current of water that passes in an undershot direction, as indicated by the arrow 0 will act on the power wheel B. The flow of the water passing in an overshot direction as indicated bythe arrow 0 will be impeded and confined by the blades 20 and the disks 1 1 and the power of the current of that water will act on the screen A. The joint power of both screen and power wheel will be united through the gears 15, 16 and 17. Thus enabling me to secure and unite the power of an undershot' andan overshot wheel in the space of one. As will be readily observed any moss or debris that will catch on the upstream side of said screen 3 1 will be carried partially around on the peripheric face of said screen and washed off on the down stream side. If the depth of the stream is not more than the diameter of the drum screen A, fish will be prevented from passing up or down the stream and will also be prevented from coming in contact with the moving parts of the power wheel B and from receiving injury thereby.

Having thus described my device I desire to secure by Letters Patent and claim 2- 1. A power wheel consisting of a horizontally placed driving shaft; an undershot water wheel secured thereon; a drum screen mounted on said shaft concentric with said wheel, and consisting of two spacedapart circular disks; a plurality of brace rods horizontally placed between said disks with their ends secured in the disks and near the peripheric edges thereof; a coarse mesh screen inclosing all of said rods; hinge rods also secured between said disks; inwardly extended lugs on said disks; blades pivoted on said last mentioned rods adapted to contact with said lugs and at times to assume a radial position; a gear keyed on said shaft; an annular gear attached to said drum screen and a pinion intermeshing with said gear and said annular gear to impart motion to said shaft.
