Abstract

A vertical axis windmill has a rotor with a hollow shaft (6) about which is fixedly mounted an annular member (8) carrying blades (9) extending radially outwardly therefrom. The blades are scoop-shaped with apertures (14) therethrough over which are placed flaps (15) in the hollow of the scoops, which flaps shut when the blades move with the wind and open when they move against the wind. A cam (7) carried by the shaft (6) acts through a follower (18) to translate rotation of the shaft (6) to reciprocating movement for actuating a pump rod (17). A rotor having a plurality of axially displaced blade carrying members (8) fixedly mounted on the hollow shaft (6) with the blades staggered so as to present in plan a uniformly spaced pattern of all the blades.
