The 32v version looks very similar to the 110v and it was the only brochure I have. Thought it might be useful. Your 85 yr old machine was designed to charge 55, 2v glass jar, lead acid batteries connected in series. I’m not familiar with a modern battery equivalent or controllers so I wouldn’t atte...

Most of these were 32V and intended to charge batteries. The 1000W rating is peak power. In average wind conditions you can expect maybe 15% of that on average ….plenty for a farm in 1939. Be cautious of 110V DC, much more lethal than 110V AC. The 110v option wasn’t as popular because it required 55...

I don’t see the prop, stub tower or controller. All things I probably have. It does appear to be NOS so I’m hoping you make it a display piece. It’s not a particularly rare model but it is rare to find one so nice. It dates to about 1939. My contact info is in my profile if I can help you locate the...

Only top view I have.
Let me know
Thanks

I believe the voltage regulator was a kit option for the 1222H model. I opened the box of a NOS one and snapped a couple pics. Hope it helps.

Not sure I have an answer you’re looking for. I’m really only familiar with (and a fan of) the early machines which were all DC. Dump resistors weren’t in their vocabulary. The last thing you want to do with a DC gen is wear out the brushes and throw the power away. Some of the mfg did have field co...

Good looking machine, some parts look NOS or a really nice older restoration

I haven't seen any literature that shows that PD variant. The droopy tail angle iron looks amateurish but you finding 3 of them spread out could mean that they were made for or by a PD retailer. The tower really interests me, one I haven't seen. It appears to be constructed the way PD did it. They b...

I recommend the American Windmill Museum in Lubbock. I know they need a Jacobs like yours in their wind electric collection. If you want to give me a call or email ( my number is in my bio) I can tell you who to talk to and contact info. I don’t like to put that info in the public domain.

The Jacobs Little America story is pretty interesting. Here’s a sequence of photos from 1929-1955. (Reverse order) 1929—1st camp—Three 70 ft towers erected for radio transmission 1934–2nd camp—Jacobs mounted to one of the radio towers. 1947–Admiral Byrd’s son visits Little America 1954—Bud Waite dis...
