CHINESE WINDMILL WATERS FARM (Oct, 1933)

That’s a really nifty way to pump water!

CHINESE WINDMILL WATERS FARM
Adapting an Oriental idea for raising water for his own needs and to irrigate his fields, a California farmer has constructed the curious apparatus shown in the accompanying photographs. Power from a windmill, transmitted through gears, revolves a spiral-shaped tube of pipe open at both ends. The outside end dips into a water-filled ditch at each revolution. Water is thus picked up, and runs by gravity around the spiral to the hub as the wheel revolves. An opening in the hub dis-charges the water into a trough four feet above the level in the ditch, giving a sufficient lift for the irrigation purposes desired.
