Abstract
Abstract A device for deriving power from the energy of water waves, such as ocean waves, includes a buoyant support base, such as a raft, adapted for floating in open waters and having a keel extending from its bottom surface for stabilizing same in a horizontal position. A plurality of open funnels are mounted on the top surface of the base for collecting a wave and directing it into a manifold mounted at the small ends of the funnels for operating a turbine generator in communication with the manifold. The bottom walls of the funnels extend outwardly of their larger ends so as to define artificial shoals lying beneath the bottom surface of the raft and thus beneath the surface of the water. The shoals cause the waves to break into the funnels, the broken waves tumbling along the funnels and increasing in speed upon movement toward the smaller ends thereof. The smaller ends of the funnels are staggered relative to one another so as to funnel the water into the manifold at different intervals for constant operation of the blades of the generator.

Claim 1
Independent Claim
219 words
A device for deriving power from the energy of moving water waves, such as ocean waves, comprising, a buoyant support base member having top and bottom surfaces and adapted to float in open waters, an elongated keel extending outwardly of said bottom surface for stabilizing said base member and maintaining it substantially horizontal while floating a plurality of elongated funnels mounted on said top surface of said base member, said funnels lying adjacent one another and having open opposite ends converging from a larger of said ends to a smaller of said ends for channeling waves along said funnels, said larger ends defining water inlets and said smaller ends defining water outlets, a manifold mounted on said funnels in communication with said smaller ends, a turbine generator having blades mounted in communication with said manifold for effecting operation of said generator as water from said outlets impinges thereagainst, and said bottom walls of said funnels extending outwardly of said larger ends and defining artificial shoals lying below the surface of the water, whereby waves of the same collection are caused to be broken by said shoals and to tumble along said funnels at increasing speed upon movement toward said smaller ends, the power of the waves thereby operating said turbine as the water from said outlets drive said blades.

Claim 3
Dependent Claim
78 words
The device according to claim 1, wherein said larger ends of said adjacent funnels are staggered relative to each other so as to lie along at lesst one line disposed at an angle to the longitudinal axis of the device, said smaller ends of said adjacent funnels lying along a line perpendicular to said axis, whereby said funnels produce water currents which reach said manifold at different intervals for causing said turbine to be operated with little interruption.
Claim 4
Dependent Claim
60 words
The device according to claim 1, wherein said funnels are of equal length, said smaller ends and said larger ends respectively lying along lines parallel to each other and perpendicular to the longitudinal axis of the device, whereby said funnels produce water currents which reach said manifold at different intervals for causing said turbine to be operated with little interruption.
Claim 5
Dependent Claim
22 words
The device according to claim 1, wherein said shoals are concave for effecting a steering of the device into the water waves.
Claim 6
Dependent Claim
96 words
The device according to claim 1, wherein pairs of said funnels are of unequal length, said funnels in each said pair being of equal length, the innermost pair of said funnels having the longest length relative to the remaining pairs, and said larger ends lying along a pair of V-oriented lines disposed at angles to the longitudinal axis of the device, whereby the waves from the same collection are broken by said artificial shoals and tumbel along said pairs of funnels at different intervals for creating water currents which reach said manifold at correspondingly different intervals.
Claim 7
