ISAAC MILES, OF BONESTEEL, SOUTH DAKOTA.

WAVE MOTOR.

Application filed July 17, 1922.

To all 1072021 it may concern:

Be it known that I, Isaac MILES, a citizen of the United States, residing at Bonesteel, in thecounty of Gregory and State of South Dakota, have invented a new and useful \Vave Motor, of which the following is a specification.

This invention relates to wave motors, and the primary object thereof is to force water from a wide expanse into a narrow space to increase the power of the so flowing water.

Another object is to so construct and mount a motor of this character that it may be raised or lowered to maintain the colleetor the proper depth in the water.

Another object is to provide a simple and strong motor of this character equipped with means for increasing the wave force.

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 may be made within the scope of what is claimed without departing from the spirit of the invention. V

In the accompanying drawings Figure 1 represents a plan view of a mo-' tor constructed in accordance with this invention.

Fig. :2 is a central longitudinal section thereof, and

Fig. 3 is a transverse section taken on the line 8-3 of Fig. 1.

In the embodiment illustrated, the motor constituting this invention comprises a floating structure 1 designed to be mounted in any body of water to utilize the power from the waves or current thereof. This floating structure 1 has a collector in the form of a shoot 2 the side walls 3 of which converge toward the front end and merge into a sluice t, the side walls 5 of which are parallel and through the front end of which extends a shaft 6 on which a drum 7 is mounted between the walls 5, said drum being of a length corresponding to the distance between said walls. A similar drum 8 1s mounted for rotation in the front end of shoot 2.

These drums 7 and 8 are designed to support an endless belt 9 to which are fixed a Serial No. 575,505.

plurality of spaced paddles or buckets 11). These paddles ll) are made substantially triangular in cross section tapering toward their outer edges as is shown clearly in Fig. 2. These paddles 10 are of a length corresponding to the distance between the walls 5 of sluice l and travel between said walls, the water passing through the sluice operating against the paddles to actuate the belt for transmitting the wave power to any desired point. The shaft (5 may be used as-a power transmitting shaft and connected with any ap aratus to be driven.

A board or plate 11 closes the top of the sluice a and the rear end thereof which e tends into the front portion of the shoot 2 is inclined as shown at 12 in Fig. operating to direct the water downwardly against the paddles.

The bottom 13 of the shoot 2 has its rear or outer edge bevel-ed as shown at Ll to facilitate the passage of the water into the. shoot and which cooperates with the converging side walls 3 thereof to force the water toward the narrow sluice el.

At the head or entrance end of the shoot 2 is arranged a vertically movable gate 15 which is shown by Figure 2 as in its closed position, but it is to be understood that the gate may be held in various positions of adjustment by any suitable means not shown. The gate is preferably constructed in the form shown in Fig. 1 having grooves 16 in the outer faces of its opposite ends which interlockingly engage with guides 17 extend ing upwardly from the side walls of the shoot. This gate 15 has a bottom 18, the front or free edge 19 of which rests on the beveled edge 14 of the shoot when the gate is in closed position.

lvhen the motor not in use, this gate is designed to be let down into the position shown in Fig. 2, and whichmay be raised any desired height according to the quantity of water which it is desired to admit to the motor. It will thus be seen that this gate will control the volume of water supplied to the motor, and it may he held in adjusted position by any suitable means.

In the use of this motor, the gate having been raised the desired extent to permit water to flow into the shoot 2 the water so admitted will pass forward under the force of the current or wave and be directed by the converging side walls 3 against the pad dles 10 and pass out through the sluice 4. This flowing of the water will turn the belt through the paddles and drive the shaft 6 for transmitting power.

As shown, this motor has two laterally extending wings or floats 20 and 21 at opposite side o'r the shoot 2 adjacent the upper portion thereof and in which are mounted a plurality of cylinders 23 any desired number of which may be employed, four being here shown.

These cylinders 23 are made hollow and watertight and are supported in suitable openings in the Wings 20 in any suitable and Well known manner.

From the above description it will be obvious that the shoot 2 being considerably wider at its head than at its eXit will cause the water to flow out through the narrow sluice and the gradual narrowing of the water to the exit gives extra power.

I claim A wave motor including a float, said float including converging Walls defining a sluice, a horizontal board connecting the side walls of the sluice and arranged in vertical spaced relation with the bottom of the float, the "forward edge of the board being beveled to directwater downwardly, drums operating at the ends of the sluice, an endless belt operating under the drums, buckets carried by the endless belt, said buckets being of lengths to engage the bottom or the sluice, and mean for admitting water to the sluice.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature. I

ISAAC MILES.
