Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
186 words
A machine for converting wave energy to electrical energy comprising a float responsive to wave action causing reciprocating up and down float motion a first means connected to the float along its vertical axis and to parallel rods causing opposing motion of said rods, each said rod connected to a piston mounted in a cylinder which in turn is connected to compressed air tank, including a check valve between each cylinder and said tank in further combination with a second means for operating an electric generator by the compressed air in said tank, wherein the first said means comprise a pair of linkages connected to the float at spaced points, each said linkage attached to each said rod, wherein one of said linkages includes a pivot point secured to a fixed member on one side of said float axis and the other of said linkages includes a pivot point secured to said fixed member at the opposite side of said float axis whereby vertical reciprocal float motion causes opposing rod motion and air compression in at least one cylinder on both up and down float motion.
Claim 2
Dependent Claim
186 words
A machine for converting wave energy to electrical energy comprising a float responsive to wave action causing reciprocating up and down float motion a first means connected to the float along its vertical axis and to parallel rods causing opposing motion of said rods, each said rod connected to a piston mounted in a cylinder which in turn is connected to compressed air tank, including a check valve between each cylinder and said tank in further combination with a second means for operating an electric generator by the compressed air in said tank, wherein the first said means comprise a pair of linkages connected to the float at spaced points, each said linkage attached to each said rod, wherein one of said linkages includes a pivot point secured to a fixed member on one side of said float axis and the other of said linkages includes a pivot point secured to said fixed member at the opposite side of said float axis whereby vertical reciprocal float motion causes opposing rod motion and air compression in at least one cylinder on both up and down float motion.
Claim 3
Dependent Claim
47 words
The combination of claim 1 wherein the second said means includes an air turbine driving a pair of pulleys which in turn drive an alternative connected to an electric circuit including a trouble switch fuse box, alternator motor combinations, an auxiliary air compressor pumps and storage battery.
