Specification of Letters Patent.

Patented Jan. 5, 1915;.

Application filed December 9, 1913. Serial No. 805,597.

To all whom it may concern:

Be it known that I, FRANK W. OMAN, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented a new and useful Water-Motor, of which the following is a specification.

This invention relates to improvements in current water motors.

An object of the present invention is to provide a current motor hingedly secured to a float so that" it may be tilted or inclined to be in operable position within the water.

A further object is to provide a wheel with a bar extending at right angles to the axis thereof and which is adj ustably secured at different heights so that the inclination of the plane of rotation of the wheel may be varied and regulated.

A further object is to provide a hingedly mounted wheel with a shaft extending substantially parallel to the hinge connection and which shaft is provided with a beveled gear engaged with a similarly beveled gear the latter being secured to the wheel. This shaft is adjacent the hinged connection so that the shaft will remain practically stationary for small adjustment in the inclination of the wheel.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferred embodiment of my invention is illus trated, in which Figure 1 is a vertical sectional view of my improved current motor and tilted at such angle as to be partially submerged in the water so as to be driven thereby. Fig. 2 is a top plan view of the foregoing.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 3 is a float and which as illustrated in Fig. 1, is very low in the water so that the top surface l thereof will approximate the level of the top surface of the water. The float is adapted to move about in the water so that broad flat board 7 and to which is secured the rearwardly extending adjusting rod 8. The adjusting rod 8 is provided with the opening 9 extending therethrough at the rear end thereof and through which opening extends the post 10, the latter being pivotally secured to a base 11. The post 10 is provided with a plurality of apertures 12 extending transversely therethrough and which apertures are adapted to register with a similar aperture 13 extending transversely through the adjusting rod 8 and through which apertures when properly alined, extends a locking pin 14:, thus holding the board 7 rigidly in any required angular position.

Mounted upon and rigidly secured to the board 7 is the Vertical bearing 15 which rotatably receives the axle 16 therein. The axle 1.6 is threaded as at 17 and to which is secured the collar 18 whereby the axle is prevented from moving out of the hearing. A beveled gear 19 is rigidly secured to the axle 16, to which gear is connected the wheel spokes 20, the latter carrying at their outer extremities, the blades 21. Thus the gear forms a hub as well as performing its usual functions. As an additional support for the spokes 20 and blades 21, the rods 22 are provided rigidly secured to the spokes and blades and radiating centrally and secured to a disk 23, the latter being threadedly secured to the axle at some little distance above the gear 19. Thus the truss rods will strengthen the wheel and provide a rigid structure. Extending between the blades are the tension members 24 whereby the various blades are held spaced apart and materially strengthened. From the foregoing it will be apparent that as the shelf or board 7 is tilted through the intervention of the adjusting rod 8 and post 10, the axle 16 will be tilted a corresponding amount, bringing the blades at one side of the wheel into contact with the water and partially submerging the same therein.

In order to transmit the power obtained from the wheel, the shaft 25 is provided, which is mounted in suitable bearings 26 spaced at equal intervals along the shelf 7.

A beveled gear 27 is secured to one extremity of the shaft and meshes with the beveled gear 19 from which it derives its power. The remote end of the shaft is provided with the sprocket wheel 28, around which extends the chain 29. In this connection it is tobe noted that the shaft 26 extends parallel to and adjacent the hinge 6 so that the movements of the sprocket wheel in common with the shaft 25 and shelf 7 will be relatively small for small adjustments in the angular position or obliquity of the Wheel. The slight shifting of the sprocket wheel is taken up by and allowed for by the chain 29. The wheel operates according to the well known principle of subjecting the blades upon one side of the axle to pressure in one direction and upon the other side causing the blades to move above and out of the water.

Having thus described my invention, what I claim is An apparatus of the class described comprising a float, a shelf extending along and hingedly secured to one edge thereof, means for locking said shelf in adjusted inclined positions, a vertical bearing carried by said shelf, an axle threaded at its extremities and rotatably supported by said vertical bearing, a beveled gear rigidly secured to said axle preventing the shifting thereof in one direction, a plurality of spokes radiating from and rigidly secured to said gear which acts in the capacity of a hub therefor,

blades carried by said spokes, a horizontal shaft extending along and rotatably mounted upon said shelf, a gear carried by said horizontal shaft and meshing with said beveled gear, means for transmitting power from said horizontal shaft to mechanisms supported by said float, a collar mounted upon the lower threaded extremity of said axle preventing the shifting thereof in a direction opposite to the limitation imposed by said beveled gear, and a disk thrcadedly i Copies of this patent may be obtained for five centa each, by addressing the Commissioner of Patente.
