Russ Huber Posted March 26 Share Posted March 26 (edited) In 1927 Signal it appears put out their first 12"-16" desk fans. These fans had DUAL WINDING motors for either/or alternating or direct current. Thanks to ELECTRICAL RECORD we now have some above average insight into Signal fans from their first fan produced in 1923 through 1928.

The switch selection must have placed the fan in series for DC operation. Son engineer William Tideman may have designed the fan as he was working for Signal until his death in August of 27. Father Henry Tideman came back to Signal to take his place. Quote Link to comment Share on other sites More sharing options...

Jim Kovar Posted March 30 Share Posted March 30 Dual wound fan... See instructions on base plate... Clear as mud. Does anyone have one with a more legible instruction tag? Would love to see it! Quote Link to comment Share on other sites More sharing options...

Russ Huber Posted March 31 Author Share Posted March 31 (edited) Steve, I am sure Jim and whoever bought the 12" example off of Etsy in 2021 for $125.00 are dying to see the switch. I myself wouldn't mind a peek at it, please. 🙂 If in fact someone actually paid $125 for the dual voltage Signal back in 2021 in the shape it was in, my bet is they watch this website. 🙂 Signal Electric Fan, Vintage Fan, Model J, Parts Repair, 12 Inch Metal Blades, Signal Dual Wound Fan, Vintage Fan Parts, Antique Fan - Etsy Edited March 31 by Russ Huber Quote Link to comment Share on other sites More sharing options...

Russ Huber Posted April 1 Author Share Posted April 1 Thanks for sharing, Steve. Signal history and fan motor line is gradually being brought to the surface thanks to 20s electrical trade and the Signal catalogues spanning 30s into the 50s provided to me by Geoff Dunaway. There unfortunately are missing catalogues early 30s. Tideman fan motor engineering at Signal spanned 1920s up until 1934. Quote Link to comment Share on other sites More sharing options...
Geoff Dunaway Posted April 1 Share Posted April 1 Wow !! I think there may be one of thoise fans out back. Always wondered about the toggle switch. Quote Link to comment Share on other sites More sharing options...

I hope you have it, Geoff. I am dying to know how they wound that stator. 2 years on the market (27-28) and done deal. 1929 Henry Tideman dumped the dual voltage for the AC induction 3 speed.

Actually, Steve, when I was referring to the "switch", this is what I was seeking, the internals. The actual switch itself mounted on the outside of the base is as I thought it was, double-throw-center off. The switch allows 2 speeds in either the AC or DC settings. The question is how did Signal wind/set-up the motor for the AC setting in a non-universal motor wind stator? The Signal catalogues that I do have are credited to Geoff Dunaway. The sad part is 1930-32 and 35 catalogues are missing. The good part is thanks to the Electrical Record we have Signal fans starting with their introduction fan motor 1923-29 covered, it appears.

Russ Huber Posted April 3 Author Share Posted April 3 Ok, thanks to Steve Rockwell, someone please wire it up and explain how they did it. Poor Signal fans, they just don't get the respect they deserve, but, my bet a complete intact example of one of these would. 🙂 Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted April 4 Author Share Posted April 4 4 wire head cord. One wire from each pole connects to a brush holder. Repulsion AC function. Series DC function. Anyone? Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted April 4 Author Share Posted April 4 (edited) 2 head wires go into the top pole, two head wires go into the bottom pole. Look how beefy those pole windings are. The fan must have been a boat anchor to carry. So how does the dual winding work? Edited April 4 by Russ Huber Quote Link to comment Share on other sites More sharing options...

David Yurko Posted April 11 Share Posted April 11 I have a gec fan that has a similar winding arrangement, it pretty much causes less resistance in the field coils to account for the inductance of running the fan off of AC vs DC Quote Link to comment Share on other sites More sharing options...
