FOR" may indeed indicates the production date to be somewhen around the application dates of those first patents, as you pointed out between 1902-1903, but before they were approved by the US patents and licensing office.

The word is not "may", it "was" manufactured during the time between patent filing and issue dates. Jandus had a 12" DC model (only) on display at the Pan American exposition in 1901. There are no images of that model I am aware of, but I think it is safe to assume it was an early ball motor example. Your double wing pivot is the first for my eyes. Chris Campell did reproduce a few switch bodies for the early models in past. I think he even went as far as reproducing the components that were on the switch.

Unless you see any evidence of previous modification of that hub, like drilling, I would leave that one alone. The blade hub on the one I previously owned was drilled out, and I had it reconstructed.

And as a result, they got the 4th place 🤣 Thanks for the link to the Western Electricity 1901 volume. I have read through it whole afternoon.

Russ Huber Posted July 30, 2023 Share Posted July 30, 2023 Sorry, don't mean to burst your bubble, but your fan wasn't manufactured in 01 on a good day. 🙂 Bernie's fan patents were FILED in 02. Your fan manufacture spans between 02 and 03. But that ain't nothin to shake a stick at. 🙂 Quote Link to comment Share on other sites More sharing options...

Lots of interesting information! Thanks for the link. Somehow I didn't find the link myself, probably because I was searching for "Jandus ball motor 63V" and the AFCA website has been weird lately. Anyhow, I read that the speed control in your fan was also missing and you had Paul Graves re-produced it for you. I am trying to contact him and hopefully he can help me with that too.

Interesting that this eBay example has the "No. 12" similar to the badge on my fan. It also has the patent date of 1903 on the other badge, so is likely manufactured later than my fan. Looking at the photos of the 2 fans side by side, there are differences observed: the pivot, the blade and the cage. The pivot has a single wing on this example (mine has 2), but it has those grips that Russ was talking about. Not sure if the blade and cage were original on that fan or replacements from a later wire mount Jandus fan. Do you know how much that fan was eventially sold on eBay?

Chris Campbell Posted July 30, 2023 Share Posted July 30, 2023 (edited) I actually am the new owner of the above Jandus fan Steve posted prior to this post. Paid around $800. It was missing a switch. I have made switch plates in the past and with the help of someone was able to complete a switch. Unaware of anyone currently producing the hardware for completing additional switches. Currently do not have any plates. May have overlooked this already answered, but regarding original question: ”The fan seems complete except its speed control is missing. Can the speed control be re-produced to make the fan run at 3 speeds as it was originally designed? Also, how would you run this fan? (with a DC power supply or using a VariAC in combination with a rectifier? Thanks all for your advices.” These motors can be wired AC or DC. My understanding is AC was 2 speed, DC was 3 speed. The 3 speed on DC would have a small choke resting on top of plate. Unmounted and often damaged. Rectifier used for DC power. If the two plates holding brushes are bridged it runs AC. If not bridged runs DC. These motors can be wired multiple ways and many variations to complex things. Below are pics wired 2 speed on AC.

Chris Campbell Posted July 30, 2023 Share Posted July 30, 2023 (edited) Switch's are often broken and pulled after the feet on base fall off. That removes clearance and weight of fan snaps plates.
