Abstract

The turbine rotor has a shaft (A) which is mounted with its axis vertical and carries two discs (D). These discs support four curved blades (V1)(V2)(V3) (V4) which can pivot on pins (P1)(P2)(P3) (P4). The two blades (V1)(V2) are held facing the wind by the stops (O1)(O2) but as the rotor rotates the blades are made to pivot by a cam operated by the rotor so that the blades offer the least resistance to the wind when moving against the wind direction. This attitude of the blades is shown by the blades (V3) and (V4). As each blade completes a revolution the cam changes the blade attitude to the position (O1) to receive the force of the wind.
