Here are two pics of an old -probably about 1940- range exhaust fan. Unlike current models, this one monted inside the duct, and plugged into an unusual receptacle. It ran on 110.
I believe that the same pattern was shown on this site as a receptacle for TV antennaes. I don't doubt that one bit- consider this pic a reminder to never assume, and that NEMA patterns haven't been with us all that long!

That sure does look like the same type of receptacle as was used for an antenna & ground connection:

Was this all factory original or probably a hack-job cobbled together by someone many decades ago?
Looking at the picture of the duct & receptacle, it looks like someone just stuck whatever recept they had on hand.

No, Sven, as best I could tell, the fan was manufactured along with the piece of duct that held it in place.
Interesting old fan. What brand? Does it still work or did it burn out? Noisy? I've seen similar in 50s/60s homes around here in wall or ceiling before range hoods became popular. Is that duct tape around the socket?
Welcome to ECN, Sockets!
The fan technically worked, more or less. Sometimes it would start, other times it would just hum. It has since been replaced.
No, that is not duct tape. Rather, it is part of a sheet-metal flange that held the socket in place.
Did you re-attach the existing cord-cap and socket?
No, the replacement fan was of the more conventional squirrel-cage type. I ran the old K&T to a junction box, with a short whip of Romex from there to the fan. As you might guess, this job involved a lot more carpentry and plaster work than electrical work!
Wonder why it would just hum sometimes? Good that you replaced it anyway.
Wonder why it would just hum sometimes?
Because it didn't know the whole song...LMAO...sorry, couldn't resist.
Because it did'nt know the whole song...
LOL!

It was probably gummed up with old cooking grease.. If the ambient temprature was warm enough, it might start, if not, hummmmm..
I had a similar problem with the ceiling fan in the kitchen at the house we rent, It was full of grease.. I took the whole thing apart, and degunked it, oiled it, and reinstalled.. works much better now..
Had to do a similar feat with the range hood (self contained, vents to room, not to exterior.), including a complete stripping of all paint, and repainting.. it was caked with years worth of cooking grease..
Such PUNishment I receive! :-)
I expect that the motor was of the shaded pole type, with some breakdown in the shading coil, so that there wasn't very much torque to get things moving the right way. There certainly was no centrifugal switch!
IME, most SP motors fail because the bushings get worn, not becasue of electrical failure.
John,
Majority of Shaded Pole motors I've seen fail has been because of rubbish stuck in the bearings/or the armature/Yoke part.
These motors don't have a lot of torque, especially while starting.
IMO, rip it out and put a Man's motor in there!.
V8, at least!.
We have one of these at a camp with a outside serface level output without cover we leave it on to keep out the rodents and if they come we repaint the bathroom
