.~ Working member actuated by the rise and fall of a surface of a body of fluid {9}

.~.~ Having articulated buoyant members
DEFINITION
Classification: 60/500
(under subclass 497) Apparatus having at least two buoyant working members adapted to be moved relative to one another by the vertical movement of the surface of a body of fluid and said members being pivotally interconnected to each other whereby mechanical work may be performed as a result of the relative movement of said members only.
(1) Note. Classification in this subclass includes only those relatively movable interconnected buoyant members which produce work because of their relative movement, per se. For devices having relatively movable working members wherein work is produced as a result of relative movement between one or more of the working members and a stationary means secured to or supported by the earth see subclass 504 or 505.
