Specification of Letters Patent. Patented Sph 9 191%} Application filed tra 17. 1918. Serial No. 235,149.

To all whom z'tmag] concern:

Be it known that I, CHARLES R. WYBonmay, a citizen of the United States, residing at Wilbur, in the county of Lincoln and State of Washington, have invented certain new and useful Improvements inCurrent- Motors, of which the following is aspecification. y y

This invention relates to current motors and has for its object the provision of a motor which may be submerged in a flowing stream and which will be so constructed that it will offer a minimum resistance to the force of the current as the working parts move against the current and will utilize to its full extent the force of the current for the transmission of energy.

In the accompanying drawings: Figure 1 isa front elevationof a motor embodying my improvements;

Fig. 2 is an end elevation ofthe same; Fig, 3 is a transverse section onithe line 3-3 of Fig. l; y

Fig. 4 is a detail perspective view ofone of the blades; a a

Fig. 5 is a transverse section of theblade. In carrying out my invention, Iprovide a cement orother substantial foundation 1 in the bed of the stream and upon this foundation I erect standards 2 which support the main driving shaft 3. Upon one end of the driving shaft I secure a gear wheel 4 when meshes with a gear wheel 5 on the lower end of a vertical transmission shaft 6 which is supported in suitable bearings carried by the.

adjacent standards 2 andmay rise to any desired height and be connected to any wellknown type of mechanism for transmittin power to the point where it is to be ut111ze To the driving shaft 3, I secure wheels comprising disks or circular plates 7 and blades 8 pivotally mounted in and extending between the disks. It will be readlly noted, upon reference to Fig. 1, that I have 1llustrated two wheels each consisting of three disks and two sets of blades. It will also be noted that the blades of one set in each wheel are arranged in staggered relation to the blades of the other set of said wheel so that, in the operation of the motor, power will be transmitted constantly and pract1- cally without interruption. This utilization of the power without interruption will be carried out to its fullest extent by disposing the blades of each wheel in staggered rela tion to the blades of. the other wheel so that at all times during the operation ,of the motor there will be blades exposedto the propelhng action of thewater. It is also to be understood that the number of wheels may be, increased or diminished according to width of the streamer the depth of the same andthe force of the current and other deter mining circumstances. r The bladeswill preferably be composed of woodenbodies 9 reinforced by metallic strapsor facing strips 10 so as. to obtain the max mumstrength without excessive weight and without making the cost prohibitive. The pivot rod "11 of theblade will extend longitudinally through the same, near one longitudinal edge and the ends of said rod or shaft will be fitted pivotally in the disks 7 near the peripheries of the same, the ends of the pivot rod being at equal distances fromthe centers of the disks so that the rod 1 willlie parallel with the driving shaft. I also securein and extend between the disks longitudinally extending rods 12.1 and 13 which perform the double function of bracingthe disks and also serving asrests or stops to control the position of the blades in the operation of themotor; The steps 12 are disposed near the peripheries of the disks,but inwardly fromthe pivots l1. and

the stops 13 are disposed at points still further inward in position to be engaged by the blades near the ends of their greater sections, and it is to be noted that the pivots 11 and the cooperating stops 12 and 13. are

all on different radii of the disks.

As previously stated, the pivot 11 is nearer one longitudinal edge of the blade than the other edge so that the blade presents sections of unequal area at opposite sides of its pivot. Referring more particularly to Figs. 2 and 3, it will be noted that when a blade is at the lowest point of the wheel, as shown by the dotted lines in said figures, it will lie horizontally and will present the edge of its smaller section to the flowing stream. The blade will remain in this position, parallel with the current, until the upper face of the greater section of the blade impinges against the stop 13 which will occur when the blade has traveled about one-third of the revolution of the wheel. The blade will then assume the position shown in dotted lines at the left in Figs. 2. and 3, and will lie on an angle of about ten degrees so that the current will impinge against the under face of the blade which is downwardly inclined and will exert a lifting force against the blade thereby serving to impart motion to the wheel. The blade will remain in engagement with thestop 13, as shown in Fig. 3, until it has traveled about one hundred and ninety degrees when the current will impinge against the then under face of the blade which is .not in engagement with the stop 13, as

shown in dotted lines in Fig. 2 at the right, and the force of the current will then swing the blade upwardly about its pivot 11 so that it will describe an arc of about one hundred degrees and assume the position indicated in Fig. 2. The force of the current then acting upon the blade will tend to swing the same outwardly and downwardly, but at this time the smaller section of the blade will have engaged the stop 12 so that further movement of the blade about its pivot cannot occur and the power of the current will continue to transmit motion to the wheel until the blade again reaches the lowest point of the wheel.

It will be readily noted that the stops 12 are rather close to the pivots of I the blades but slightly nearer the centers of the disks or side plates of the wheel than the pivots, while the stops 13 are located near the radius upon which the respective pivots 11 are located but much closer to the centers of the disks or side plates. When the blade,

therefore, is swung about its pivot, as described, the larger section of the blade will be carried away from the stop 13 and its smaller section brought into engagement with the stop 12 so that the blade cannot at once assume a position parallel to the current, but will be reversed so that though it begins to travel against the current it will utilize the force of the same for producing power. Inasmuch as the inner stops 13 describe a smaller are than the outer stops 12 and the pivots, the continued travel of the wheel will gradually bring the free edge of the greater section of the plate to and against the respective stop 13 so that without being reversed the blade will assume a position in which it will be acted upon by the current to transmit power.

My wheel can be built at a low cost and when set up for use and in operation will transmit power continuously, the arrangement of the parts being such that each blade is inactive during only about one-third of its travel and, if the wheel be equipped with four blades, during the period of inactivity instead ofone blade there will be three blades actively transmittingthe force of the current. a

Having thus described my invention, what is claimed as new is:

A blade vfor a current motor consisting of a wooden plate, metallic reinforcement secured upon the faces of the plate along the edges of the same, and a pivot rod extending longitudinally through the plate near one longitudinal edge thereof and parallel with said edge and having its endsprojecting beyond the ends of the plate, the reinforcements being united to form a support for the rod.

In testimony whereof I aflix'my signature. CHARLES R. WYBOBNEY. [1,. s]
