A vertical-axle wind power machine comprises a vertical axle, a plurality of jointed radial arms, a plurality of counterbalanced oblique blades at the support points thereof, a friction-rewarding rotary speed multiplying transmission, and an automatic rotary speed regulating means to be performed by either a wind-operated or an alternative digital controlled rotary speed regulating device; the combination of which provides the oblique blades with great sensitivity to the alternation of lee wind and head wind for automatic swinging to the most efficient lee angle at upstanding and overturned positions to sail nearly three quarters and streamline against the head wind resistance for the remaining quarter every circle of rotation, is able to convert the centripetal and centrifugal component forces to the same torque direction of the tangential component force from the same blade by an eccentric-guided angular bracket means and a fork-rooted radial arm, is able to offset the friction loss in the rotary speed multiplying process by pairs of bushed multiplying gears serially coupled between a pair of paralleled vertical shafts in connection with the vertical axle, and is able to output a stable and desired rotary speed by either a wind-operated or an electronically controlled rotary speed regulating device regardless the variable wind speed.

[ What is claimed is:] [1.] A vertical-axle wind power machine comprising:a multipurpose turbine framework which comprises a vertical axle and a plurality of radial arms secured to said vertical axle;a plurality of sets of oblique blades respectively mounted on said radial arms of said multipurpose turbine framework, wherein said oblique blades are divided into four wings by a cross coordinate at the support point thereof; along the latitudinal axis the after two wings portioned wider than the fore two wings leaving said two wider wings performing as guide wings and said two narrower wings performing as counterbalancing wings, and along the longitudinal axis the outer wings portioned longer than the inner two wings leaving said two outer wings performing as master wings and said two inner wings performing as counterbalancing wings, is provided with appropriate counterweights in the counterbalancing wings to maintain a balance condition at said support point thereof, is tilted to an adjustable angle below 45 degrees from the radial blade axis upon said radial arm by adjusting the length of stay means jointed between said radial blade axis and said support point thereof, and is defined to swing within a range of 180 degrees between the upstanding and overturned positions thereof by appropriate stop means; anda multiplying transmission comprises a pair of paralleled vertical shafts and pairs of bushed multiplying gears serially coupling between said paralleled vertical shafts to multiply low speed rotary motion transmitted from said vertical axle to high speed rotary motion for an output.
