Application July 6, 1932, Serial No. 621,120

Claims. (CI. 170—67)

The present invention relates to windmills and has. particular reference to a windmill wherein the wings revolve about a vertical axis.

An important object of the invention is to im5 prove the general construction of devices of this character.

Another- very important object of the invention resides in the provision of means for adjusting wings in an easy and convenient manner.

A still further very important object of the invention resides in the provision of a windmill of this nature which is simple in its construction, inexpensive to manufacture and construct, thoroughly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in _____ _{owlllg bllt! uuuu} view as will appear as the description proceeds, half into the wind so that one half of the winged the invention resides in certain novel features of rotor will be acted upon by the wind, construction, and in the combination and ar- The pin 18 is extended through a rod 22 slidable rangement of parts as will be hereinafter more in a bore in the upper portion of the shaft 5 it fully described and claimed. ’ ......

This ar- practice it attains the features of advantage _uo rangement eliminates projecting parts on the disk which would form an air resistance to the rotary movement of the disk.

The links 15 are pivotally engaged as at 16 with a plate 17 slidable on the shaft 5 and having a pin 18 extending through a slot 19 in the shaft 5 so as to rotate with the shaft 5.

Obviously the vertical movement of the disk or plate 17 will change the pitch of the wings 10. A semi-circular hood 20 is disposed on the upper portion of the shaft 5 and houses the wing structure just described so that approximately one half thereof projects outwardly therefrom to be engaged by the wind. In order that it may have a proper position according to the direction of the wind the hood is provided with a tail 21 or vane which will automatically swing the hood
