CURRENT-MOTOR OR WATER-WHEEL.
SPECIFICATION forming part of Letters Patent No. 774,592, dated November 8, 1904.
Application filed May 16, 1904:- Serial No. 208,282. (No model.)
To all 2077 0712, it may concern.-
Be it known that I, JOHN SMITH TVIATHEWS, of Pendleton, in the county of Umatilla and State of Oregon, have invented certain new and useful Improvements in Current-Motors or lVater-Vheels; and I hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form part of this specification. i
This invention is an improvement, in waterwheels or current-motors; and its object is to provide a simple and efficient feathering-blade water wheel or motor which can be operated either in a vertical or horizontal position and either wholly or partly submerged, being particularly adapted for generating power for use in irrigating plants, as local power apparatus on farms, and for general powerpurposes.
The invention consists in the novel construction of the wheel, as hereinafter described and particularly claimed and as illustrated in the accompanyingdrawings, in which Figure 1 is a top view of the wheel, showing it arrangedto operate in a vertical position. Fig. 2 is a view showing the wheel arranged to operate in a horizontal position.
Fig. 3 is an enlarged detail view of one of the blade-lock hinges.
The wheel comprises a drum A, which may be a regular circle in circumference, but is preferably polygonal, as shown. This drum may be constructed of metal, wood, or any suitable materials and is preferably watertight, particularly when the wheel is to be used in a horizontal position. It is fixedly attached to an axial shaft B, which is journaled in suitable hearings in beams O C, projecting from suitable supports, and a jetty or deflect-or D is attached to and between beams C C at the return side of the wheel, which will assist in directing the water against the buckets, wings E, or blades on the power side of the wheel and will facilitate the closing of the blades at the return side of the wheel.
Around the periphery of the drum is ardrum is polygonal I preferably provide a blade for and of sufficient size to cover each facet of the drum. These blades preferably have flanges e on their ends, which flanges may form part of the hinges F of the blades.
The hinge members F are pivoted at f to the ends of hinge lugs or arms Gr, rigidlyfastened to the ends of the drum and projecting slightly beyond the periphery thereof, so that the pivots f are at the periphery of the drum. The hinges F project inwardly beyond the pivots f,these projecting portions forming stop-arms F, which are adapted-to move under the fixed hinge arms G as the blades swing outward until they strike the base portionG of the fixed hinge-arms, as indicated in the drawings, when they arrest the further outward swinging of the blades and cause the latter to transmit the full force of the current to the drum to rotate the latter. The fixed arms G, it will be observed, form the supporting members of the hinge. They also form stop members of the hinge, and they also form guards to protect the arms F as they swing thereunder. The flanges e aid in keeping the water current directly against the blade and give the blades a kind of dish or concave form, which is enlarged by turning the outer edge of the blades slightly inward, as indicated at e of the drawings.
When the complete wheel is placed in the water, the force of the current at one side of the wheel will swing the blades open and cause the drum to rotate in the direction of the current, while the blades at the opposite blade-hinges are located some distance from their pivots, there is less strain on the hinges and less liability of the parts becoming disarranged-or damaged by wear than would occur if the lock were at the pivot.
A light spring-band J may encircle the wheel, this band having one end attached to the jetty and then passing loosely around the l wheel back to its point of attachment to the i etty, where it is or may be connected to a rope or chain passed under or over a guidei of longitudinally disposed blades, locking hinge-arms attached to the ends of said blades, fixed guard hinge-arms attached to the ends of the drum and projecting slightly beyond roller and back to a Windlass-drum, which i the periphery thereof, and pivoted to the lock 7 can be operated by lever K or other suitable l hinge-arms, said lock hinge-arms projecting device. hen the band is loose, it will not inwardly beyond the pivots and adapted to interfere with the opening of the blades on engage the inner ends of the guard hingethe power side of the wheel nor the free acarms, to lock the blade in open position, and
