Wind driven prime mover
A vertical axis wind driven prime mover has plural circumferentially spaced horizontal wind driven arms carried by a central hub which is attached to a central vertical axis rotational working shaft. Each wind driven arm carries multiple fixed blades or louvers which can extend horizontally or vertically on the arms. The louvers of each arm are constructed and arranged to act as impulse elements when the arm is moving with the wind on one side of the vertical axis machine and to form reaction motive elements when moving against the wind on the opposite side of the vertical axis machine. Each arm of the prime mover additionally includes fixed wind confining or pocketing members along its leading and trailing horizontal extremities at both the top and bottom thereof and at its inner and outer ends. Each arm carries a fixed angular vertical flange at its outer end to propel the arm in the proper direction when the arm is aligned with the direction of the wind. The wind can drive the assemblage of arms in only one direction with the rotational working shaft and the prime mover is essentially unitary without relatively moving parts in the assembled device. Structural simplicity and operational efficiency are achieved in a practical machine. The prime mover can also operate in a denser fluid medium, such as water.
