Prairie Windmill Model

Description
This model represents a horizontal paddle-wheel windmill of the type used to some extent on the prairies of the United States. The model shows the windmill set up to pump water to an irrigation flume. The axle of the wind wheel is mounted on bearings supported on the top of a board fence that encloses the lower part of the paddle wheel.
Paddle-wheel windmills differ from the sail-wheel mills in that the paddles move in the direction of the wind rather than across the wind, and it is necessary to make the paddle-wheel feathering or shield part of it so as to prevent the wind from striking the paddles that are moving in the direction opposite to that of the wind. The axis of the paddle-wheel type may be either horizontal or vertical. The use of the horizontal type is limited by the fact that it operates only when the wind is in the direction nearly perpendicular to the axis of the wheel.
