Definitions

  • This invention relates to a device for regulating the number of revolutions, as well as the performance, of wind-wheels by'turning and at the same time shifting the vanes upon their arms with the aid of curved guide members, the difierence between the centrifugal force arising in the vanes and a uniform-counter-force being used as the re-ad ustmg power.
