Abstract
Abstract An elongated U-shaped pipeline has floats pivoted on transverse axes for rocking thereon in response to wave action in water which the floats are buoyant. Rocking of the floats operates pumps arranged in pressure compounding relation and the fluid under pressure is delivered to a shore-based storage tank. The storage tank being sealed allows build up of a pressure head. The fluid is let out through a regulator to operate machinery. Spent fluid from the plant is spilled out into a recovery tank, directly under the motor or turbine. It is then picked up by the lower leg of the pipeline and returned to repeat its cycle again. The floats support the pipeline and can be flooded to sink below the surface to avoid damage by storm waves.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A wave operated power apparatus on a fixed base adjacent a body of water comprising: pipe means extending outwardly from said base and adjacent the surface of said body of water; a plurality of support means arranged serially on said pipe means defining generally horizontal axes transverse to said pipe means; float means journaled on each of said support means, about said axes, and arranged to float on said body of water to buoyantly support said pipe means and to oscillate about said axes in response to waves in said body of water; separate pump means connected between said float means and said pipe means and responsive to oscillatory movement of said float means about said axes for compressing fluid and delivering compressed fluid to the inlet of an adjacent pump and finally to said pipe means whereby said pump means serially compound the pressure in said fluid; and motor means on said base, connected to said pipe means, for using said compoundly compressed fluid to generate power.
Claim 2
Dependent Claim
168 words
A wave operated power apparatus on a fixed base adjacent a body of water comprising: pipe means extending outwardly from said base and adjacent the surface of said body of water; a plurality of support means arranged serially on said pipe means defining generally horizontal axes transverse to said pipe means; float means journaled on each of said support means, about said axes, and arranged to float on said body of water to buoyantly support said pipe means and to oscillate about said axes in response to waves in said body of water; separate pump means connected between said float means and said pipe means and responsive to oscillatory movement of said float means about said axes for compressing fluid and delivering compressed fluid to the inlet of an adjacent pump and finally to said pipe means whereby said pump means serially compound the pressure in said fluid; and motor means on said base, connected to said pipe means, for using said compoundly compressed fluid to generate power.
Claim 3
Dependent Claim
39 words
Apparatus as defined in claim 1 wherein said pipe means is connected to said base by means of an articulated connection whereby said pipe means and float means may rise and fall in response to changes in water level.
Claim 4
Dependent Claim
48 words
Apparatus as defined in claim 1 wherein each said float meaNs comprises a transverse shaft journaled on its support means and hollow float bodies fixed to respectively opposite ends of said shaft on opposite sides of said pipe means, said shafts being drivingly connected to said pump means.
Claim 5
Dependent Claim
99 words
Apparatus as defined in claim 1 wherein said pipe means comprises a pair of parallel pipes, said support means being secured to both pipes to hold the same fixed relative to each other; said pipes being connected at their outer ends to define a single fluid conduit; the inner end of one of said pipes being connected to deliver fluid under pressure to said motor means and the other being connected to said motor means to receive spent exhaust fluid therefrom; and check valve means in said fluid conduit arranged to confine fluid under pressure to said one pipe.
Claim 6
Dependent Claim
36 words
Apparatus as defined in claim 4 including a storage tank on said base for accumulating fluid under pressure from said one pipe; and conduit means for directing fluid from said storage tank to said motor means.
Claim 7
Dependent Claim
50 words
Apparatus as defined in claim 1 wherein each pump means has an inlet and an outlet, the outlets of all but the innermost of said pump means being connected to the inlet of the next innermost pump means whereby the pressure of said fluid is compounded by successive pump means.
Claim 8
Dependent Claim
76 words
Apparatus as defined in claim 2 wherein said float means comprises hollow bodies, buoyancy control means in said hollow bodies for flooding the interiors thereof with ambient water and for evacuating water therefrom; and selectively operable means on said base for controlling operation of said buoyancy control means for selectively flooding and evacuating said hollow bodies whereby they may be caused to float at a desired level relative to the surface of said body of water.
