Abstract
Abstract A wave powered pumping system including a floating platform and a plurality of floats hinged about the periphery of the platform. A double acting piston pump is provided on the platform for each float, with the float driving the piston of the pump utilizing both upward and downward movements of the float in a variable stroke operation. Nozzles for water jets may be carried on the platform below the water line to provide positioning and/or propulsion forces for the platform. In one embodiment, the platform is free floating; in another embodiment, the platform moves up and down with the swells and has a telescoping pipe anchor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
131 words
In a wave-powered pumping system, the combination of: a floating platform; an accumulator tank carried on said platform; a plurality of pumps carried on said platform; means connecting the pump outputs to said tank, each of said pumps having an input opening below the water line of said platform; a plurality of floats; means mounting each of said floats to said platform for relative pivoting motion of the float and platform about a generally horizontal axis; means connecting each of said floats to a corresponding pump whereby relative pivoting of the platform and float actuates the pump; first and second vertically disposed telescoping pipes with the upper pipe connected to said tank and with the lower pipe adapted for anchoring; and a gimbaled mounting for supporting said tank on said platform.
Claim 2
Dependent Claim
