Hi, I never thought that there was anyone else that liked fans. Well, I was wrong! Um, at the burger king near me, there used to be 5 ceiling fans there. The vents were in a shape of an S, color antique brass, 4 blades, no light kit installed although possible. Does anyone know what this is?

Cool, thanks. I was asking because they have been there all of my life and recently, they replaced them with Hunter Passports.

What sort of canopy did they have? Did they have flywheels? Was the switch housing large or small, and were they variable speed?
They could have been Homestead, Old Jacksonville, or Evergo.

Yes. They have some S-vent fans you can find on eBay.

I've searched VCF, I have found the exact model. This is great! Also, the building is now knocked down, along with the Hunter Passport II's They have demolished the Burger king, along with a rental store, chinese restaurant, and a Tommy K's to make way for a Walgreens. A new, smaller Burger King is built on site. Such a waste, considering there's already 3 other pharmacies, a Hanthingys across the intersection, a CVS on the other side of the intersection, and a Kaye's up the street. The Homesteads were grease bombs, wobbling horribly, and for some reason, the one in the corner had a flywheel or something that was dropped lower than the motor housing. How can this be?

Homesteads have flywheels very prone to breaking.

...and for some reason, the one in the corner had a flywheel or something that was dropped lower than the motor housing. How can this be? The only thing that comes to mind is an isolator ring. Here, let me quote myself: The rubber flywheel, sometimes called an "isolater ring" (although that term typically refers to an add-on for the Hunter Original fans), served as a noise-deadening agent. Let me explain this: I don't know if you've ever seen a tuning fork: Basically, it's a piece of metal which is cut to a very exact shape and size. When you strike it on a hard surface, it (very quietly) rings an exact pitch. Before the age of electronic tuners, these are what was used to tune musical instruments. Anyhow, when you would bang it against an object (like a table or countertop, for example), it would sound its pitch. But it was very, very quiet in doing that. So here's a neat little trick: you bang it against a table, and then you (still gripping it by the part at the bottom where the two tines converge into one metal rod) hold it on top of the table so that the metal ball on the bottom is firmly in contact with the table. Guess what happens? The whole room is filled with the fork's pitch! The table acts as an amplifier, similar to the huge metal horn on an antique record player ("gramophone"). That feature (which is a study in resonance, which itself is a subdivision of physics) was very useful in tuning pianos--it made the fork's pitch loud enough that it could be heard in comparison with a note on the piano. But that same feature works to great DISADVANTAGE in ceiling fans. The motor is like the tuning fork--it has a quiet hum (a vibration) to it. The blades, being connected at the flywheel, act as the tabletop--they amplify that hum and make it pretty darn loud--often too loud for the fan to be a good "bedroom fan". If you have a really high-power motor with a big hum, such as an Original, it's kind of necessary (in bedroom situations, if you're sensitive to hums) to have a rubber isolator ring between the blade irons and the motor, so that the vibration won't transfer into the blades and therefore won't be made highly audible. So that's the trade-off: fans WITH the rubber flywheel may require more parts and labor. Fans WITHOUT the rubber flywheel are louder. Rubber isolator rings used to be fairly commonly available as a cheap do-it-yourself noise-reduction agent.

Dan, the fan works fine, so an isolator ring might be what the black thing was, as Piece described. The blade brackets were pretty darn close to the switch housing. It's odd though because only one of the 5 fans had it.

It spins but it was off balance, correct?

No, it was perfectly balanced, unlike a couple there that shook like no tommorow. One of them had a bent blade bracket, and the fan was like 15' in the air, I thought it was going to fall off! When they replaced them with Hunter Passports, the fan in the place of the one with the bent bracket was wobbling too. I'm guessing there's something wrong up in the ceiling when it, i suppose, was knocked loose.

Ben, I'm saying all this tongue-in-cheek, so don't think that I'm trying to be mean! :-) No, it was perfectly balanced, unlike a couple there that shook like no tommorow. One of them had a bent blade bracket, and the fan was like 15' in the air, I thought it was going to fall off! When they replaced them with Hunter Passports, the fan in the place of the one with the bent bracket was wobbling too. I'm guessing there's something wrong up in the ceiling when it, i suppose, was knocked loose. Double-take : I'm guessing there's something wrong up in the ceiling when it, i suppose, was knocked loose. First off, I have no clue what you actually just said. That sentence looks like something Bush would say during the course of a State of the Union address. It makes zero grammatical sense. But I think I know what you were getting at; still, correct me if I'm wrong: You're saying that there's something screwed up with the ceiling, possibly due to the removal of a previous fan, and that is why the current fan is wobbling? If that's what you meant, then congratulations! You just won the award. It is impossible for a ball & socket fan (which is what Hunter Passport is) to wobble due to anything related to the ceiling. You can mount a hugger on a vaulted ceiling. It's not the world's best idea, but I've seen it done. The fan, in that situation, doesn't attempt to wobble. Wobble is not related to the angle at which a fan hangs. Wobble is caused by an imbalance between different blades--whether due to weight, a bent blade iron, warping, etc. Imagine this experiment: You have a small lightweight ceiling fan (let's say a 36" spinner) assembled on the floor. It has a 24" downrod on it. You've wired on a lamp cord, which is plugged into an outlet. You turn the fan on high and pick it up by the downrod. You can hold that fan parallel to the floor. You can hold it perpendicular (at a right angle) to the floor. Hell, you can hold it upside-down. The fan is not going to wobble. You could swing it like a fire baton, to no effect. The fan doesn't care what angle it's at. All that matters is whether all the blades are balanced in relation to each other, in terms of weight and position. I need Carlos Mencia to do that "dee dee dee" thing...

Yes, you correctly interpreted my jumble of a sentence. Yay, an award. Do I get anything else?
Actually, the Passport wasn't mounted on a downrod at all. They bypassed it and directly mounted the canopy to the motor (don't ask my they dould do that on a 15' ceiling), essentially making it flush-mount. I'm guessing that the Homested (which were mounted on 4' downrods) that had a bent blade wobbled for years like that, f-ing somthing up in the ceiling (did I say it right this time?).
The guy who replaced them probably neglected to fix it, leaving it to wobble. They were barely up for a year.
If you hold a ceiling fan up like you described, does it have a gyroscopic effect?

The guy who replaced them probably neglected to fix it, leaving it to wobble. No, you're still wrong. Here, look at this colorful diagram of a ceiling fan, mounted without a downrod, on a f'ed-up ceiling: That fan would not wobble. Ben, fans don't wobble from not being hung on a level surface. Fans wobble because the blades are not aligned relative to each other. So, if a blade is out of alignment because it is warped, the fan will wobble. If a blade is out of alignment because a blade iron is bent, it will wobble. But if all the blades are in-line with each other, and all weigh the same (i.e. you don't have three 21" blades and one 17" blade), the fan will not wobble. The condition of the ceiling is equally as irrelevant as the chemical formula for Amur leopard blood. Wobbling is the visible result of weight shifting. Picture the fan blades' cumulative sweep path as one circle (in this diagram, it's the large lavender circle): If one section of that circle--one piece of the pie, so to speak (or, an "arc" in mathematical terms)--weighs more than the rest of the circle, then gravity will exert more force on it. Therefore, it will be pulled down further. As it spins around (when the fan is on), constantly being pulled on harder than the rest of the circle, it causes the fan to tilt on its axis (the downrod)--in other words, it makes the fan slant. When that happens repeatedly, in a cyclical form, it's called "wobbling". Here's an alternate way of thinking about it: The Giant Evil One-Armed Fan of Spidery Death, also known as the Enigma, doesn't wobble, even though it only has one blade. That's because there's a counterbalance weight installed on the opposite side--a hunk of metal which weighs exactly as much as the blade it opposes. Since both sides of the circle are balanced, relative to each other, the fan does not wobble. And yes in theory, if you twirled the fan fast enough, you'd get a gyroscopic effect.
