Patent ID: 6863505

Claim:
A wind driven pump, comprising: a wind vane comprising at least one vane and which rotates about a center of axis; a shaft operably interconnected to said wind vane, and which turns when said wind vane rotates, said shaft comprising a first portion positioned at a first location, and a second portion positioned at a second location; a means for converting rotational motion to reciprocating motion which is operably interconnected to said second portion of said shaft on a first end and at least one piston on a second end; at least one piston rod operably interconnected to said means for converting rotational motion to reciprocating motion, wherein when said wind vane rotates a piston interconnected to said piston rod reciprocates; at least one pump chamber operably interconnected to said at least one piston, wherein when said at least one piston reciprocates, energy is provided to a column of fluid wherein said fluids travels to a predetermined location; and a means for selectively altering a stroke length of said at least one piston based on a speed of rotation of said wind vane.
