Behold the King!!!!

For the longest time I have felt this interest in Emerson's "less desirable" fans know as the Northwind Line. This line has all steel blades. Most of the motors are AC/DC universal. Near as I can tell Emerson began making these little monsters around 1916 (based on AFCA info) then I don't know how long.

The first Northwind I ever bought one of the first line know as the Type 44's. I understand from a source that the very first was a Type 44A, then B, then C, etc... Mine happens to be a "C". I bought it off ebay from a lady in Washington I think. Some northern state... Anyway, when I got the fan, one of the brush housings was broken and the spring was missing. The fan sat on my shelf for a long time as I waited to get to it in restoration. I had considered having a friend machine some new ones for me, and in fact we did one. Then the strangest thing happened, our maintenance guy showed up in my office one day with some brushes from some old motors. Guess what...perfect fit. yes they were not period correct technology, but they fan runs great now...

Then one day a friend of mine gave me two Emerson Northwind 450's. One was actually a 450J and it was in terrible condition. From these two fans I learned about rewiring and repairing switches made with nichrome resistance wire. Not nearly as complicated as it sounds... I have an AutoCAD blueprint if your interested... My wife also bought me a Northwind 450 for our 10th Anniversay. It was this 450 that really drew my interest to the Northwinds. Something about the speed and the sound of these fans really impressed me.

Sorry this is so long. I watch ebay just as many of you do, and I had seen a Northwind labeled 444A and 444B before. There is also one in the AFCA gallery. I thought to myself, "Self, you need one of those." Somehow I never got around to buying one. They one day when I felt like my fan buying had slumped, I saw something that made my eyes bug out. An Emerson Northwind Type 55. I couldn't believe it. I looked like one of the first Seabreezes, 8" and beige. This leads me to believe it would made around the same time... People work with me on this!!! I got this fan in oiled it up, and it ran great. Even has that faint smell of burnt carbon that I had come to appreciate in the Northwinds.

Lastly, Monday of last week my latest addition came in. A Northwind Type 444B. (see photo above) It was in pretty bad shape. The brush cap was missing and so was the spring. (Still haven't decided on the proper feedback for this fella). I had some parts laying around so I grabbed them and threw them together with a little love and oil and spare parts (new wire "Hancock Green", new plug) the fan ran for the first time in 20 years I bet. Judging from the rust. Welcome to the family little guy.

Yeah I know some of you are convinced I have lost my mind (Oh BTW, thanks for the little 12-step comment... you know who you are... ;)) Just in case you aren't convinced, I have decided to do a research project for the Northwinds. I don't know how in depth I can even go, but it will be fun just to see. If you have any information start sending it. See my post on the AFCA's site, they must think I'm crazy too, only one person has responded. Thanks for the encouraging words Darryl.

Later yall.

Balancing Blades

I had a question sent me the other day. "How do you balance blades?"

First let me say, there are better ways of doing this than my way, but I don't own a strobe light nor do I know how to use one. That being said, here goes....

I have a couple fans that when they came to my "Fan Family" (I like that better than collection) they would run okay, but they were so out of balance that they would walk across the floor on their own. After applying my method they work really well.

First thing you will need to do is remove the cage. Second, find some point on the motor that you can measure from. (I usually use the handle if there is one.) Then you rotate the blades, measure each one in relationship to the stationary point. This will give you some idea of which one is off. (usually there will be one critter that is straying distinctly bad) Once you have located the offender mark it with a sharpie or something with a little mark that is discrete. Then, and this is the difficult part, I use my hands, vise, or channel locks (depending on the blade/hub) cautiously to bend the blade slowly back into place ****VERY IMPORTANT**** Don't bend the blade itself. This is how blades are broken or creased, as you often see them. YOU MUST TRY TO BEND AT THE HUB.

This information is blade specific. If you have a cast iron hub, don't try this, it will break. If your fan's blades are brass, be very careful, brass is very easily bent.

This is the best I have for info on this topic. If you are still unsure of your abilities. I would suggest getting more information first or seeking a professional for assistance. There is nothing worse than destroying a fan with your own hands... GOOD LUCK!
