Abstract
Abstract A wave motor is comprised of two or more parallel rotors having apertured radial paddle elements with hinged flaps or blades covering the apertures such that upon the impingement of water upon one side of the paddles the blades cover the apertures and the wheel is turned, but upon impingement of water against the other side of the paddles the blades swing open. Each pair of rotors are coaxially mounted and designed for rotation in opposite directions to maximize extracted power regardless of the predominant current direction, and a single take off shaft is coupled to the rotors through a ratchet and gear mechanism.

Claim 1
Independent Claim
261 words
A wave motor comprising: a. a pair of rotors having spaced coaxial axles; b. each of said rotors having a plurality of radially extended paddle elements and each of said paddle elements being provided with a plurality of apertures; c. each of said apertures having a blade dimensioned to cover same and hingedly connected to the respective paddle adjacent the respective aperture and radially inwardly thereof; d. all of the blades of one of said rotors being hinged to one angular side of the paddle elements and all of the blades of the other of said rotors being hinged to the opposite angular side of the paddles opposite; e. each of said axles having one end thereof adjacent the other of said axles and each of these adjacent ends having a bevel gear journalled therein; f. a power take-off shaft disposed between said rotors and perpendicular to the axles thereof and having a bevel gear engaging the bevel gear on said axles; and g. each of said axles having a right ratchet wheel mounted thereon adjacent the bevel gear thereon, and each of the bevel gears on said axles having a pawl engaging the respective ratchet wheel such that each ratchet wheel engages the respective pawl when the rotor on the respective axle is turning in the angular direction opposite to the angular side to which the blades thereon are attached, whereby said power take-off shaft will be activated by one of said rotors when turning in one direction and the other of said rotors when turning in the opposite direction.
