end to the frame work as shown to normaally keep the tail vane to its work. If desired an additional gear wheel may be employed so as to multiply power. As this is a well known 5 means of multiplying power I have not shown it in the drawings. Modifications in detail may be resorted to without departing from the spirit of the in- vention or sacrificing anyof its advantages. io What I claim as new is- 1. A wind wheel consisting of a hub, a rim, blades held in said hub and rim each alter- nate blade being substantially L-shaped in cross section each alternate intermediate 15 blade being practically flat and arranged at 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 and
the 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 shaft, the horizontal sprocket chain running 25 over all of said sprocket wheels, the pump rod, and connections between the same and the disk, the tail vane and the spring connected at one end to the tail vane and at the other to the frame work, substantially as shown and 30 described. In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. CHARLES R. BOWMAN. Witnesses: J. R. BURT, J. N. P. CRAMER.
