keep the tail vane to its work. If desired an
additional gear wheel may be employed so as

an angle to the L. shaped blades and a ring
holding the inner ends of t'he main portions of
the blades, as set forth.
2. The combination with the standards andthe horizontalframe work thereon, of the wind 20
wheels journaled one near each end of said
frame work, sprocket wheels on the shafts of
the wheels, the crank disk mounted on the
standards and having sprocket wheel on its

and connections between the same and the
disk, the tail vane and the spring connected
