Claims.—(1.) In means for using the action of waves as a motive power, the combination of a pontoon attached to near the end of a lever, said pontoon free to move in any direction except to twist, and said lever free to move up and down, with cords or ropes attached to the pontoon where there is the greatest movement, said ropes actuating drums so as to give a rotary movement to a main shaft, all substantially as shown and described, and as illustrated in the drawing. (2.) In means for using the action of the waves as a motive power, in combination, a pontoon, ropes from it or a platform fixed to it to drums furnished with ratchet motion, with guide-sheaves and a lever, for converting the erratic motion of waves into a circular motion, substantially as set forth and as shown. (3.) In using the waves to give power, in combination, a pontoon attached by swivel joint to a lever, with ropes from the pontoon where motion is greatest to drums, so that every motion of the pontoon causes a movement of a drum and consequently of the main shaft, substantially as shown and as described. (4.) In using the waves to give power, where applicable, a cable or bridge stretched across from shore to shore, with a pontoon swivelled to same, and ropes from pontoon to drums, substantially as set forth and as explained.
