Patented Apr. 21, 1936 PATENT OFFICE WINDMILL Leon Zanoski, Coral Rapids, Ontario, Canada Application August so, 1934, Serial No. 742,139

1 Claim.

This invention relates to new and useful improvements in a vertical windmill. Its primary object being to devise a windmill having vertical vanes pivotally supported and rotatable in a horizontal plane, to be mounted directly on a vertical shaft.

A further object of the invention is to devise means whereby to offset the centrifugal force on the larger area of the pivotally mounted vanes.

With these and other objects in view the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set forth, claimed'and shown in the accompanying drawing, forming part of this specification and in which:-

Fig. 1 is a plan view of my improved windmill shown with the upper disc support removed.

Fig. 2 is an elevation therof.

Fig. 3 is a detail sectional view of a vane showing construction of the nose.

Referring more in detail to the drawing, in which similar reference characters designate corresponding parts throughout the several views it will be seen the invention comprises a supporting frame I0, having a vertical shaft ll rotatably mounted therein. On the upper end therof is a horizontal disc or plate l2 forming the lower support of the vanes. Said plate is keyed to the shaft and is rotatably mounted and supported on the frame I!) by means of anti-friction thrust bearings l3.

The vanes generally denoted as M, are supported vertically-between the lower plate I2 and an upper plate l5, and are mounted on vertical pivot rods l6, mounted in the said upper and lower plates, said vanes comprise a sheet of metal having a groove" formed therein at a predetermined distance from one edge thereof, said groove forms one half of the bearing for the pivot rod 16, a V shaped nose piece l8 having one end longer than the other is positioned on the short end of the vane and is constructed with a corresponding groove l9 therein to register with the aforesaid groove H and retain the pivot rod therein. This arrangement provides a balanced weight on both sides of the rod although one side has a greater exposed area and is intended to balance the centrifugal force on each side of the pivotal center of the vane, created when the windmill is operating. A plurality of stop rods 20, which also secure the top and bottom plates together are arranged in an inner circle and form means limiting the pivotal motion of the vanes. A plurality of stop members 2| are similarly arranged in an outer circle to limit the pivotal motion in the opposite direction.

In operation it will be seen the wind, which is represented by the arrows in Fig. 1, strikes the vanes which are resting against the stop rods and revolves the device until a complete half revolution has been made. As the vane starts to return the wind catches the larger area thereof on the reverse side and swings it away from the stop rod until it strikes the outer stop member. The weighted nose is thus brought directly into the wind and the vane continues its partial revolution thuswise until it resumes its former position and engages the stop rod again. It will be seen that due to the weighted nose the centrifugal force created will be equal on both sides of the pivot rod owing to the balanced construction as before described, otherwise the larger area of the vane would swing outward against the wind and impede the progress to a large degree.

It is believed that the construction and advantages of the structure shown will be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawing without further detailed description. a

While the preferred embodiment of the invention has been disclosed it is understood that minor changes in the details of construction, combination and arrangement of co-operating' elements may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

I claim:-

A vane for wind wheels comprising a pivot rod, an elongated plate having a transverse groove formed near one end thereof, and a V-shaped nose member fitted over the end of said plate, one

side of said member being longer than the other side and having a transverse groove formed therein adapted to co-act with the groove in said plate to form a bearing for said pivot rod.
