Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
139 words
A wind driven electric generating device comprising a support, a first wind driven cylindrical cage type turbine for rotation in one direction mounted on said support, a first bearing race mounted on the bottom portion of said first turbine and a second wind driven cylindrical cage type turbine for rotation in the opposite direction mounted on said support coaxially below said first turbine, a second bearing race mounted on the top portion of said second turbine, one said wind driven turbine carrying the armature of an electric generator, the other said wind driven turbine carrying the stater of said electric generator, a disc disposed on said shaft between said two turbines, and ball bearings disposed between said first bearing race and said second race and caged in by said disc to provide synchronization of rotation of said two turbines.
Claim 2
Dependent Claim
139 words
A wind driven electric generating device comprising a support, a first wind driven cylindrical cage type turbine for rotation in one direction mounted on said support, a first bearing race mounted on the bottom portion of said first turbine and a second wind driven cylindrical cage type turbine for rotation in the opposite direction mounted on said support coaxially below said first turbine, a second bearing race mounted on the top portion of said second turbine, one said wind driven turbine carrying the armature of an electric generator, the other said wind driven turbine carrying the stater of said electric generator, a disc disposed on said shaft between said two turbines, and ball bearings disposed between said first bearing race and said second race and caged in by said disc to provide synchronization of rotation of said two turbines.
Claim 3
Dependent Claim
119 words
The device of claim 1 in which said two turbines are provided with air scoops at their outer periphery and means for adjusting the angle of attack of said air scoops, said last named means comprising an arm disposed on said shaft having a slot forming a trackway, a bar having a counterweight disposed at one extremity and fastened to said air scoop at its other extremity through a lever and constrained in motion by a pin on said bar which rides in said trackway of said arm, and biasing means between said arm and said bar to encourage said air scoops to a maximum attack angle relative to incident wind when the wind is blowing at a minimum.
