Abstract
Abstract A wave pump apparatus includes a number of upstanding cylinders connected together by a subframe. Each cylinder mounts a float on the outside of the cylinder connected to a piston within the cylinder. The upstanding cylinders are spaced approximately a distance of half of an average wave length from the main floats of a particular wave pattern such that as certain floats are moving upwardly, other floats are moving downwardly. Each cylinder is connected to a chamber at the bottom thereof with an inlet valve and an outlet valve, such that as the piston in the cylinder is moving upwardly, it will draw in water, and as the piston moves downwardly in the cylinder, it will pump the water.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
A wave pump apparatus comprising a super-structure type frame, floats mounted on the frame below the super-structure and adapted to float the frame, the floats including at least a pair thereof which are spaced apart one from the other a distance approximating the average wave length of a particular wave pattern of a body of water, a plurality of wave pumps provided below the super-structure, each wave pump including a cylinder, a piston movable in the cylinder, a float on the exterior of the cylinder directly connected to the piston, chamber means communicating with the cylinder, a generator provided on the super-structure and communicating with the wave pumps, and each wave pump adapted to supply water under pressure to the generator for turning the generator.
Claim 2
Dependent Claim
125 words
A wave pump apparatus comprising a super-structure type frame, floats mounted on the frame below the super-structure and adapted to float the frame, the floats including at least a pair thereof which are spaced apart one from the other a distance approximating the average wave length of a particular wave pattern of a body of water, a plurality of wave pumps provided below the super-structure, each wave pump including a cylinder, a piston movable in the cylinder, a float on the exterior of the cylinder directly connected to the piston, chamber means communicating with the cylinder, a generator provided on the super-structure and communicating with the wave pumps, and each wave pump adapted to supply water under pressure to the generator for turning the generator.
Claim 3
Dependent Claim
51 words
A wave pump apparatus as defined in claim 1, wherein the wave pump cylinders are provided within sea leg casings adapted to support the apparatus on the sea bed in the case of submerging the apparatus, wherein the floats can be partially flooded for lowering the super-structure below the sea level.
Claim 4
Dependent Claim
33 words
A wave pump apparatus as defined in claim 1, wherein the wave pumps are located on the frame such that no one wave pump is aligned with any two floats for the frame.
