Fantastic addition Nick, congrats !!!

When will you release a pic of the whole board, i´m quite curious

Well... Since you asked...  ;)

I have sent pics to John Loughner in case he recognizes where this one came from. To me it is either made from two 50's of different eras or put together by someone that had access to leftover factory parts... The tube glass boiler (2 heater) and dark blue cast base don't fit the time period of the copper-brick smoke stack support and the 15-D generator...

Also came with a nice 504 burner and a very well made lineshaft.

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?[/size]

Thank you for that explanation Jan. Yes the ring is split and one side of the windings go to one half and the other side the other half with a brush on each side. I have disassembled this and began carefully cleaning, but unfortunately it was stored in a very poor environment and some of the clear coat is missing from the windings... will it still work?

The clearcoat on copperwire used for windings on motors/generators usually is very sturdy, so i strongly assume that it on this one appears more damaged than it in reality is.

If that isn´t the case it most likely won´t work...or at least produce a very different output than intended, as the number of windings effectively would be altered with shorts in there.
However, if the clearcoat missing is solely on the outside of the exterior windings, it shouldn´t effect anything since the voltage output of this generator is relatively low.


In any case, be very gentle when cleaning that area...

Fingers crossed from here Nick !!!

I have only dusted the winding area as I do not want to do any damage, but the areas of the copper that are darker feel rough like there is no coating, almost like the copper had corroded through the coating... It's very easy to take this one apart, so I will test it as is.

Nick you've got a DC generator!  It's as rare as hens teeth and then some.


It is the only one I have seen.

The boiler and engine are both late 1950's through 1961. They engine is identical in color to my 1961 example and boiler with site glass tube, no rivets, and an end to end staybolt also correct for late 1950's through early 1960's. Remember alot of Jensens made when he first started using bricked sheet metal also had dark blue engine and generator parts.


The generator is also of the correct time frame which is anytime after 1951 when he started using the same 3 piece magnet used today.


By the way, if you had to, I imagine you might be able to get Andy and Dorita to rewind your coil.


A big CONGRATULATIONS, Nick....!!!


Very well done......!!!!

Wow Nick, super interesting & this is certainly a different example from the usual Jensen fair, Congratulations !

I knew that the copper brick fireboxes were used with some dark blue engines but I have never seen it on a 50...

And I did not realize the generator could be that old, I had always assumed these were a later design, like late '80's to early '90's

Let's cross our fingers that it will work with the current windings  ;)

Thank you Gil, it was a long drive back peeking at the engine through the rear view mirror. By the way, seen your call I missed, I'll give you a call tomorrow.

Thanks Bruce, I knew the firebox was a replacement, but I was hoping the lineshaft and tool design would have been a custom build by one of the Jensen customizers. John Loughner did not recognize it...

I do like the grinder, but it is too large and does not fit with the rest of the tools. The lineshaft is very well made and I would like to keep the set-up pretty much as is minus the grinder. I would like to move one of the end tools in and put a Jensen windmill on and maybe a water tower in one of the other empty spots. I have lots of 3/4" oak plywood that I can double up as the base is not the best...

I will more than likely keep it flame-fired as I have always thought it would be neat to have one, but would never have the heart to do it to an original. With a little fixing up I think this would make a great "center-piece" at a show  8)

Here's the heavy-duty grinder with oil cups, unfortunately missing one of the screw on caps



And lineshaft with flat-belt pulley

It appears the mud daubers have been busy inside the firebox



and in the boiler (also one under the engine frame)



And this crispy little spider has been hanging around a few years

The steam line has an added Stuart lubricator. The engine was stuck, but I filled the line with oil and oiled all the parts letting it sit over night. It freed up and turned over quite easily but had something in the exhaust.



After turning over a few times the oil started to push it out further



And out, allowing the engine to turn over much easier

Looks to be a bit of a grungy mess, but who wouldn't love to be the one cleaning it up and fettling with it to get it back in service!?!?

I know I would most certainly love to be that guy!!!

Daniel, I am very happy to be that guy!! And also very thankful the previous buyer left it untouched on his coffee table the past few weeks. Luckily the nickel plating is usually quite durable on these older Jensens.
