My Longest "Steam Drive" Yet! - Jensen 50
« on: July 03, 2019, 11:43:09 am »
Made a deal yesterday morning and headed down to Owasso, Oklahoma at noon and was home by 9 am this morning.

1260 miles, 19 hours of driving and a very understanding 8-month pregnant wife, 4 year old and 2 year old  :D :D

Nothing like driving halfway across the country in the middle of the night for a toy  :D

You are a road warrior like me, Charlie, and perhaps a few more. We never let over a thousand miles of driving get in the way of anything important!

Looking forward to the rest of the story.

Well... I've always wanted one of these 15's, so had to go get it!

I figured you'd be proud of this trip Gil  ;)

By the way, that's the name of my dad's truck  :D

Nick, you have probably landed the rarest of Jensen generators.  I believe those were only made to use on Jensen 50's and 51's and produced AC & DC... something I have never understood how possible from same generator, but it's true.

Hell of a drive, but rare and desirable for sure.

This whole purchase is a confusing one... quite a mis-match of parts... (more to come)

But as for this 15-D, the lamp-post is built into the base itself, on the 51's it has a stand-alone lamp-post and is also stand-alone on the Jensen museum page 15-D/lineshaft/saw combo

I used to be crazy too Nick (thinking of my Feb. trip to NJ for Maggie) but I understand - what's a thousand miles when it's for something really great............ and it definitely is - well done!

I would love to understand how this one generator can produce both AC and DC...does anyone know a layman's explanation???

The standard #15 AC "alternator" we all know runs with a simple solid slipring for the brush (second "brush" on some cast iron versions is the bearingpost itself, and the shaft acting as the second solid slipring), allowing the current to switch direction according to the magnetism induced, whereas a DC generator needs a split ring commutator, to keep a fixed positive and negative.

If you look at the picture of Jack Boyle´s generator shared above by Nick, you can see that it has two "rings" for the brushes, one in each end of the shaft, making it possible to draw both AC and DC from the same permanent magnet.

Did that make any sense?

I do however wonder about Nicks new acquisition...
My eyes could be deceiving me, but it appears that it has just one commutator, and that looks like a split ring type, which would make this a pure DC generator.
Perhaps that would make this one even rarer than the "ordinary" dual output Jensen 15D?
