Hello everyone,
This is my first post on this forum. Thank you for having me. For 20 years I have been using 1930s 16’' Emerson fan. I love the way they work how smoothly they  operate. Beautiful build quality very few things in the industrialized world  can compete short of what may be in a hospital or a science lab. Unfortunately someone I know ran on speed three for too long. I've always kept it on low speed. Stupid would you floor a 1952 Chrysler that's never been rebuilt? Not me!

I have two issues I would like help with. Next to the oil filler tube there is a little bump shaped thing I assume is the breather. It has been since getting thick oil or grease deposits pushing through. I have never opened this baby  for any maintenance or repair. It has worked very well and I was afraid to mess with it. The other problem is it has stopped oscillating due to no lubricant getting to the round turning joint . Can someone tell me why these two things have happened. What do you suggest I do to repair it thank you. 



Alex 
p.s. I have a smaller one I will be asking about too .

Hi Alex, you have one of the best fans made but even they have a few weak areas that might have been made with better materials (no pot metal).  Below is a 1930s ilustration that may help you understand how the fan is put together.  The "breather" on top of the gearbox I am thinking is the brass cap looking thing.  That is only a place where one of the gear shafts pivots in and there is no breather in the fan.  

Lack of lubrication can cause some parts to get stiff or even freeze up.  You want to make sure the head of the fan can rotate back and forth easily with no binding.   Just push it back and forth.  With the oscillator linkage disconnected as in your photo that should be easy.  If it won't rotate then find the location that it pivots on.   Might be the base stud below the motor (No.8 in the illustrations.) that goes down into the neck of the fan.   I rarely take my fans apart so am no totally up on all aspects of these fans.

Take apart as needed, clean and reassemble with oil or grease where needed.   The gearbox should be removed and the old hard grease removed (I use a flat head screwdriver, Q-tips, etc.).   Gearbox does not have to be filled, just a good coating of multipurpose grease on the gears.  It would be a good idea to remove the blade and take out the rotor from the motor then thoroughly clean the bearing in and out as well as the four small "slits" on the outside of the bearing and the 4 tiny holes at the ends of the slits.   A bent small paper clip can be used to scrape out the old dirt and oil that can clog those channels and holes..   Not hard to do but you may need some guidance here and there.

If the mostly pot metal adjusting collar (No.7) is broken then it will need to be replaced.   A member makes replacement steel collars at a reasonable price.   

Your fan is a 1928 model (no date code on the motor tag which started in 1929) but this model was made from 1928-39.   Hope this helps and gets you started.

A few observations- it appears your fan needs a cord replacement. If it's truly as bad as it looks in your pics, I'd not suggest using the fan until you have it replaced. 

Secondly, it's a little hard to see in your pics, but the oscillator arm appears to have been rubbing on something. Also as I look at the hole on the end, it appears to be egg-shaped from wear. 


Thirdly, I've never seen grease coming out of the oscillator like it is on yours. Perhaps the upper bearing that you're calling a breather has become dislodged or there's a crack in the oscillator case. 


My second or third observation might be enough to cause jamming of the oscillator mechanism. 


Welcome to the forum!

Alex, where are you located? Perhaps a local member can repair your fan or teach you.

Thank you Steve, Lane, and David. Sorry it took me a while to respond back. I live in the New York City specifically in Queens. I love to meet up with somebody who is a member of the forum and learn from them. I took a film of the fan in operation and wanted to upload it , but it didn't work I think I have to reduce the size. I have a MacBook Pro. I want to do all the work that Steve suggests but I can tell you the head of the fan won't turn and is stiff unfortunately.Lane, I'll wipe off the grease and see if I find any cracks don't expect to find any.
I now just did,  there are no cracks anywhere that I can see. I noticed that the oscillator arm is definitely bent down. I am sure it can be taken off heated up and straightened out. How best should I go about loading a video of the fan? I look forward to working on it which now seems to be the time. 
What is your opinion of it having been run on the highest setting for hours do you think this harmed it  ?

Alex B.

If properly maintained and in good condition mechanically and electrically, running it should not pose any problems. But running an unrestored fan without proper maintenance can certainly put undue drag on the motor and cause problems. 


Also, I'm hosting a meet in mid September in the Philadelphia area. Guests are welcome and it's a great opportunity to gain some expertise as well as buy good fans at reasonable prices. The details are in the events calendar here in the forum.

No harm at all, the fan was made to run on any speed forever (within reason and proper periodic lubrication).  It's not like a car where they last longer when run in the mid-range of possible speeds.
