Three 21646 variants in timeline order.  Earlier 1914-15(16?) long motor tag..... 1916(?) box motor tag.....box motor tag with 1917 introduction carry handle.  Any other variants known?

No steel guard 21646 models? 1917 was the big time transitional year for Emerson brass to steel guards, and introduction of the 12" and 16" carry handles. 

When did that box shape motor tag with no motor handle get implemented??  Either 16, or very early 17??


Emerson manufacture data supports the 216xx oscillating models off the market for the 17 season. I think I have that right?  :wondering: :D

Steel cages for 1918.  

Strong evidence through imaging and hints in Emerson articles in 17 electrical trade the brass guard was transitional to steel in 17. All images are from 17 electrical trade. There is nothing in 18 electrical trade documentation to support the steel guard implemented for that season.

I have a 21648 motor with box tag and carry handle.  Not a peep about the carry handle in 16 electrical trade.  Did Emerson carry the 216xx model manufacture into dirt early 17 fan motor season??  Did Emerson market the 216xx in 16 with box motor tag and no carry handle??

286033.  Your example lost its original ratchet case and was replaced with the more hardy later adjustment case.

Indeed it has, Russ. I own too many Emersons that would use a detent, I'd be able to buy another 21666. So only one of them got the detent wheel. The 1919 27666 that is bedside. Only fan in the room that you can see the wheel on. It got the Bravi super plate after the cap crumbled, as they tend to do. $100/ea is just too much money, then you're gonna need the Bravi cap if you intend to use them. 

List of fans I restored put ratchet cases on that should have detents:
21645
21646
21666
21648
24666
27648
Guess most are not truly restored, but I ain't made of detent money. 😅

The speed coil in either big or small motor could be swapped and has a strong potential of operating either fan efficiently as both fans operate at roughly the same wattage. Alex is credited for the heads up on that one.

Early 27xxx type #s with cast embossed speed numbers was the cut off for the use of the ratchet case.

27646 seen below is as found.

It is a failed design that was in use 1914-19. Emerson implemented a second patent adjustment wheel around 18 that had a brief window of manufacture. Your better off with the last patent design as it is hardy as h ell, especially if you run your Emerson frequently.

Indeed. And I believe it was you that warned not to use it. I used it, as it "seemed strong". Well, wasn't much longer and it happened.
Fan before resto as-was.


And what had happened during the night.


Then Jerry to the rescue with one of his last plates and spring. I couldn't bring myself to paint his handiwork. So it got a gloss clear coat to cap the wheel.


And over a year now enjoying the 27666 with 29646 switch(you brought up earlier).It is a 1919 embossed base variant.
