Wind-driven electricity generator - has radial arms carrying rotatable vanes which present min. surface when travelling against wind

摘要

A wind driven machine for generating electricity has a vertical shaft which supports radial arms. Each radial arm carries a vane which can rotate about the axis of the arm. Each vane is connected by a system of belts and pulleys to a horizontal shaft at the base of the machine. This horizontal shaft is connected by bevel gears to a stationary disc. As the vertical shaft rotates the vanes rotate so that they present the maximum area when travelling with the wind and the minimum area when travelling against the wind.
