 I have read countless threads, looked at so many pictures of GE fans that my head has spun around as many times as this fan probably has. I have a fan that belonged to my grandfather and I'm simply trying to find out more info about it. I'm just looking for an approx. mfg date, type, and any interesting facts about it. Any help from anyone would be greatly appreciated.

That's what's generally referred to as a GE Big Motor Yoke (BMY).  It has the profiled cage support arms, so I'd guess 1911 based on that and the serial number.  They're great fans, pretty much bulletproof.

Thank you very much. That certainly gives me more info than I previously had. I know my grandfather had that fan in the basement for as long as I remember.

        Gary,   Would you kindly take another look at that machine tag, at the broad space across the center, which has what appears to be a smudge more or less directly underneath the "60", but which might be a letter, or a letter and a number, since that is where GE frequently stamped designations, when they even bothered to do so. I'm suspecting letter "M", or letter "N"... would appreciate knowing whether or not it carries such information... Thanks.

Cleaned it up a little but it still appears to be a smudge.

Steve, I've never seen (that I recall) anything being stamped on a BMY in that long block that looks like a big waste of space to not contain anything.  Since Form Numbers weren't in use during the BMY era, have you seen some other stampings there that might have meant something at the factory?  Just curious.
Jim

        Jim,   I'm trying to fill in the figurative blanks as well as the literal blanks, that long block that looks like a big waste of space to not contain anything, and so far it appears that form designations were used by GE in the "middle ages" between Pancakes and WW1 production, but were not, for whatever reason, stamped on the motor tags. So, as I poke around, I'm looking for the best possible evidence, which would be stamped designations on actual production units. As of this date I have insufficient exposure to actual units to draw hard conclusions, still very much a novice, so I cast about wherever I might find info. Gallery photographs sometimes have, and sometimes have not, clearly legible tags to peruse. As you point out, not all or even very few GE fans of that era (pre-1915) have any Form stamping whatsoever. I've seen some photos the labeling of which lead me to the statement above, that GE used Form designations in the paper trail even when they're not displayed on the tags. My present thinking is: that Form L corresponds to the Sidewinder oscillator, Form M to the Kidney, Form N-- still working on it whether kidney? or likelier first round-back?, Form O- I suspect was never used to avoid misreading, Form P Roundback, Form Q Collar oscillator, RSTVW the better-known final design oscillator. Of course, there were stationary types, also given Form designations consistent with model year of production, and of course there are those pesky numbers attached to the letters, to create a myriad of possibilities, and the only thing I'm comfortable now concluding about alpha-numerics now is that those ending with 3 seems to pertain to residence fans.
       So, the short answer is that I haven't seen stampings, but am looking for them precisely, where they might exist, should they exist, to "fill in blanks" in our understanding.

              I really like seeing that Riviera, as well...

Hi Gary and welcome! Those fans are very good runners when restored. Due to their age they usually need a complete electrical and mechanical refurbishing to put them in good, safe running condition. If you use the search function on the forum, you'll find a ton of help there. Use the term "BMY" in your search to find posts specific to that fan.  

Your's could have at least 2 motor designs, so if you decide to do the restoration yourself, post pics of the switch/ coil and we can let you know which type you have. 

Best of success! It's cool to have a nice fan from your grandfather!

Now I got it Steve, I'd never thought about the possibility (actually, I'd think probability) that GE used Form letters/numbers in the paperwork even when they didn't stamp them on data plates.  I suppose it's possible that some motors may have been stamped regardless of the policy.  Good luck in your quest!  And the Riv is needing some new Mickey Thompson ET Street Radials on the rear!    Jim

Steve, I am pretty sure that the GE Form letters pertain to a YEAR and not a model so any fan made in the same year would have the same Form letter.   I think I have seen a few inconsistencies here and there.

   I think I have to disagree about Form=Year. This excerpt is from your 1923 Supply Parts Bulletin:



   I'm thinking Form equals version, meaning essentially Year/Design, the way it's written in the parts literature. If Form equals year, of the three choices above I would have to opt for 1913, 1914 being clearly identified with Form Q, and 1915 with Form R. And if it's the same design, why give a new Form letter anyway? Form V seemingly spans a couple of years, Forms RST also do not clearly follow year assignations. Without changes to the oscillator mechanism in the stationary fans, no new design, no need for new letter.




   Notice the round-back cast in the motor cap... which I think is a defining characteristic of Form "P" oscillating fans. I agree there is a rough equivalence to year, but plainly not absolute consistency which would have been tempered by the early introduction of a next year model, or late production of a prior year to use up parts, which might help to explain some of the anomalies... such as a Form "S" with earlier serial numbers than the majority of Form "R"s...  There's more to say, but I'm pressed for time right now...

Those are some of the inconsistencies I have seen regarding the stationary models that went for a few years using the same Form letter.   I don't have a great idea of how GE used the Form letters but they do move along and change with the years, not the models necessarily.

So I have a quick question. I am good at wiring electronics, I can follow wiring diagrams, I know electricity but when it comes to fans, all I know is that they blow air. lol Who would be a good person/company to restore my grandfather's fan back to it's original glory?

Kim Frank is a G.E. Restoration expert. He may or may not be taking work right now. If not lots of others on this forum can do A superb job. Maybe some of them will chime in. Good luck Old Sport!
