초록

A wind-driven machine having a hollow shell body supported on an upright rotatably mounted mast. The shell body is formed by multiple elongate shell segments circumferentially distributed about the mast. The shell segments are pivotally mounted for pivotal movement between closed and open positions.

A wind-driven machine comprising: an elongate hollow shell body disposed with the longitudinal axis thereof in an upright position, said body being shaped as a rounded cone and having the smaller diameter end thereof located over its larger diameter end, an internal support for said shell body and means rotatably supporting the base of said support for rotation about an axis corresponding to the longitudinal axis of the body, power-generating means connected to and driven by said support, said hollow shell body being formed by plural elongate shell segments which follow one another in a direction extending circumferentially of the body and each segment extending from adjacent the top end to adjacent the bottom end of said body, each shell segment in longitudinal cross section curving outwardly and downwardly progressing downwardly from the top end thereof and in transverse cross section having a concave side facing inwardly and a convex side facing outwardly, each shell segment having leading and trailing edges and being pivotally mounted for pivotal movement about an axis extending adjacent the trailing edge thereof from adjacent the top to adjacent the bottom of the shell segment between a closed position where the segment imparts part of the cone shape of the body and an open position where the trailing edge of the shell segment moves outwardly and the segment is disposed transversely of its closed position, an opening existing along the leading edge of the shell segment between the leading edge and said support with the segment moved from its closed position, and means for producing pivotal movement of said segments rotated to rotational movement of said support.
