This intermediate or partially opened and closed position of the vanes is shown in Fig. 3. With a furtherrotation of the windmill, the opening and closing of the previously closed'and opened vanes is completed, the previously closed vanes being now in position to be fully engaged by the wind, as shown in Fig. 4. When this vane unit in turn again moves out of the wind the relative position of the opposed pairs of vanes is again reversed.

In Figs. to Z a modified arrangement is shown. In this case each vane unit is single, the vanes 8a and 9a'being mounted on alined shaft sections 5a connected at their adjacent ends a torque spring 11 within the central bearing block 6a. In this arrangement the vanes 8a when vertical depend from the shaft and the corresponding horizontal vanes face away fromthe wind, being held from upward movement by stops 1'2 projecting from the band 366. Counterweights 13 applied to the ends of the shaft sections act to balance the vanes so that they normally lie in positions at right angles and parallel to a wind- 7 plane respectively so that they are always in ,position to take advantage of the slightest breeze.

The springs 11 between the shaft sections prevent possible breaking or warping of the vanes in a high wind, since while the springs are sufficiently strongto resistordinary wind pressures and hold the vanes vertical, they yield under excessive pressure and permit the vertical vanes to flatten out backward, or

with the wind. It may here be notedthatthis 1 same arrangement may be used in connection A. hood 16 is secured to the shaft 7 From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as :set forth herein. a

While this specificationsets forth in detail the presentand preferred construction of the device, still in practice such deviations from suchdetail .may be resorted to as do not form a departure from the spirit of the invention, asdefined by the appended claim.

Having thus described my invention what I claim as new and useful and-desire to secure by Letters Patent is:

A windmill including an axial support, longitudinally alined and-separate shaftsec tions projecting across the same, said sections terminating jadj acent :each other within the support, vanes on the outer ends, of the shaftsections, .and a torque spring connecting c the shaft sections attheir adjacent ends'an arranged to cause the vanes to normally lie at ,right angles to each other and yieldably resist turning of the shaft sections relative to eachother inonedirection.

In testimony whereof I afiix-mysignature.
