Vintage Windmill and Wind Generator Forum

Thanks Dan and Mike for the info on pull-out and pull-in windmills

Hi -
A nearby ornamental Aermotor 702 has a crank on the tower, not a furling lever. Is this a pull-out winch? If so, any idea what kind it is? Casting numbers L266 and L265 on the thing.

Also, does a pull-out/pull-in winch cause the wheel to move parallel to the vane, or cause the vane to move ...

Thanks Justin, I didn't know that.

Bob and Buzzard -
I just came across a Fairbury near Bennett CO that said "Winmill" on the case. Interesting that other people have seen this also.

Bob - maybe the well was so deep the wind pressure wasn't strong enough to drive the pump rod at the time we stopped, altho it was previously when we drove up. I like this hypothesis!

Justin - I was also thinking the pointy vane might be easier to make than a nice curve and that's why it was made ...

What an interesting demonstration of wind currents - if you know any science teachers I'll bet they'd love to show this clip to their class.

Came upon this Aermotor, it was turning when we drove up. Then it stopped turning although the wind continued to blow. I felt the pump rod, it was frozen in place. The associated stock tanks were full. No regulator on the mill, tail isn't furled, furling lever was pointing up. Is there some other ...

Awesome pics, and a helpful reference
Thanks, and happy Memorial Day

That's interesting!

Aha! Thanks for the excellent info. Love the color-coded mill, I was studying that pic and wondering how it oiled itself.
