Abstract
Abstract A wave operated power plant is described wherein a buoyant vessel is anchored on the ocean surface with the wave motion forcing ocean water up through vertical pipes in the hull causing rotation of blades in the pipes thereby through shafts rotating electrical generators and generating electricity, the water exhausted from the tubes being discharged onto a deck above the ends of the pipes and to the ocean.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A wave operated power plant which comprises a vessel having a hull, a plurality of flotation and ballast chambers carried within said hull, at least one vertically extending tube extending upwardly from the bottom of said hull, water deck means contiguous to the hull water line above which said tube terminates, a discharge passageway being provided for discharge of water from said water deck means, said passageway having at least one port extending through said hull and haVing an outwardly opening door for permitting water discharge but preventing entry of water from outside said hull, water driven members in each said tube having an output shaft, and electric generator means connected to each shaft.
Claim 2
Dependent Claim
114 words
A wave operated power plant which comprises a vessel having a hull, a plurality of flotation and ballast chambers carried within said hull, at least one vertically extending tube extending upwardly from the bottom of said hull, water deck means contiguous to the hull water line above which said tube terminates, a discharge passageway being provided for discharge of water from said water deck means, said passageway having at least one port extending through said hull and haVing an outwardly opening door for permitting water discharge but preventing entry of water from outside said hull, water driven members in each said tube having an output shaft, and electric generator means connected to each shaft.
Claim 3
Dependent Claim
114 words
A wave operated power plant which comprises a vessel having a hull, a plurality of flotation and ballast chambers carried within said hull, at least one vertically extending tube extending upwardly from the bottom of said hull, water deck means contiguous to the hull water line above which said tube terminates, a discharge passageway being provided for discharge of water from said water deck means, said passageway having at least one port extending through said hull and haVing an outwardly opening door for permitting water discharge but preventing entry of water from outside said hull, water driven members in each said tube having an output shaft, and electric generator means connected to each shaft.
Claim 4
Dependent Claim
114 words
A wave operated power plant which comprises a vessel having a hull, a plurality of flotation and ballast chambers carried within said hull, at least one vertically extending tube extending upwardly from the bottom of said hull, water deck means contiguous to the hull water line above which said tube terminates, a discharge passageway being provided for discharge of water from said water deck means, said passageway having at least one port extending through said hull and haVing an outwardly opening door for permitting water discharge but preventing entry of water from outside said hull, water driven members in each said tube having an output shaft, and electric generator means connected to each shaft.
Claim 5
Dependent Claim
34 words
A wave operated power plant as defined in claim 1 in which a water trough is provided along the bottom of said hull with which the lower end of said tube is in communication.
Claim 6
Dependent Claim
23 words
A wave operated power plant as defined in claim 2 in which said trough is centrally located on the underside of said hull.
