Multi-contact slide switch in base?

It is GE.  Ain't it?   :wondering:

Probably a DC base, not sure of the year.

So, the DC version had switched

resistor in its base?

I have a DC pancake trunnion base somewhere. It looks similar, but I don't recall the holes for the connections. I would have to dig it out. I meant to bring it to Indy for Kim to identify but forgot.

    The first fan in the 5th post is 1896 12 inch trunnion type FD form A . It has 1-1/2 inch of iron in the fields. The base is fluted
    The second picture has a step pulley on the shaft. My guess for the holes in the base is to secure the motor. The holes are not on the same circumference as the holes on the 1899 bracket base pictured in the sixth post.
    All four fans pictured in the 8th post are 1899 models.
    The picture that Steve posted  in the 10th post is a 1899 12 inch trunnion type FD form E. That base is fluted and has a boss cast into it for the terminals. Also the last year for that style of motor and base in DC.
    The DC offerings in '97 and '98 were stickmount and smooth base.

Nice. That is the base for the 1899 DC pancake motor. I have only seen one DC pancake and it is the 1897 12 inch solid frame model. I have worked on the 12 inch 1899 DC stickmount but it is the roundball motor....You've heard of the Gemerson. It is a '97/98 12 inch DC pancake with a 1899 GE cage and struts on it. It has a four wing Parker blade on it and a motor tag claiming it to be an Emerson. In reality it would have a cage with integrated struts and a six wing blade. I guess that would make it the "second" DC GE pancake I've seen.


The base holes are for the exposed cord terminals and headwire to exit up to the rear motor terminals, just like the Bracket fans and the 16 inch type UI form C.....

Rick's fan that was on the cover of the latest issue doesn't count? I know it was a pic, but still, I almost fell off the throne. You need to get him to bring that up north so we can all see it...

Rick's fan is the first DC Pancake I ever saw. It doesn't belong to Rick anymore, as it changed hands last Spring. Bill Hoehn's "Gemerson", is a stump with parts not original to it. Here is how it should look....which by the way, this image will be gracing the back of the new AFC museum tee-shirts coming out next year...

A big thank you to Jim Kovar for passing along the info to get this base for the museum. Even though it is incomplete, it is an important part of GE history and will be on display for all to see in the GE time line. The owner of the '97 dc stick is allowing me to use the specs of his fan's switch, which I'll reproduce for this base. Thanks again Jim.

Really like the look of the cast iron completely stripped of paint. Be interesting to see a complete fan done this way?

Traced out the diagram...


Slow -- field coils in series


Fast -- field coils in parallel



Either way the armature is



in series with the field,...


id est a series motor.  :thumbup

Why do some of the samples shown have the exposed terminal leads at THE TOP of the motor?

That's an idea. I'll put it on my list of things to do here at the shop, just behind the other 396 projects ahead of it....Just FYI the first picture posted is the 1899 12 inch trunnion Type FD Form E. The last picture posted is the 1896 12 inch trunnion Type FD Form A. I don't know of any collector who has either complete example...

Having the leads top side makes total sence if running to an overhead fixture.

So at long last, the GEmerson is declared a frankenfan? But wasn't there supporting documentation?

How much money would you like to wager on the Gemerson Frankenfan statement?

The GEmerson is proof that Emerson realized early on that if they were going to have a good product, they were going to have to use a GE platform and put their stupid looking blade on it......

If there was some documentation that the GE/Emerson was in fact an Emerson offering and not a put together job by some hack, I'd think it would be worth a pretty penny to the right person....

You would have thought the research diggers of the group would have produced something by now.  I may be with Nick, an overplayed piece of manufacturer seconds thrown together as a fan.  Would love to see some documentation.....come on kovar and russ
