Abstract
A wind driven generator comprising a shaft having one end rotatably mounted in the apex of a conical wind deflector, a wind wheel keyed on the shaft in an open housing behind the deflector. An armature is mounted on the other end of the shaft in close proximity to a stator in a housing so that when the shaft is rotated by the wind the armature rotates in the stator to generate an electric current. Semi-circular perforated shields are hinged in front of the wind wheel so as to cover the space between the periphery of the housing and the outer edges of the deflector. The shields are held open by a counter weight until the wind attains an excessive velocity.
Claims3
An electric current producing windmill comprising a windwheel having blades thereon;
- a generator;
- a housing for said windwheel;
- said housing includes a front disc having an open circular area and a dished peripheral wall;
- a conical wind deflector mounted centrally of said disc, and forward of the windwheel, for deflecting wind to the outer part of said blades;
- a shaft having one end rotatably mounted inside the forward tip of said deflector;
- said windwheel being keyed thereon;
- the other end of said shaft being coupled to one shaft of the generator for rotating same;
- and a pair of perforated semi-circular shields, one of which is hinged on each side of said deflector;
- said shields linked to means to pivot said shields about their respective hinges to a closed position for automatically covering the space between the outer periphery of said deflector and the inner periphery of said wall when the wind velocity exceeds a given speed, said perforated shields allowing wind currents to flow through perforations in the shield so as to power the windmill and its coupled generator when the shields are in the said closed position.
