Steve Rockwell Posted May 7, 2022 Share Posted May 7, 2022 I’m posting a series of 1890's fan images, perhaps weekly, or at least until a correct response is posted. In theory, each succeeding image should become more difficult to identify than the previous; in cases where the fan isn’t so hard to name I’ll likely post just a partial image to make the task a bit more of a challenge… I’m expecting the final two or three to possibly be real stumpers…..

Russ Huber Posted May 7, 2022 Share Posted May 7, 2022 There is a clue that gives it away other than its shape. Electrical trade advertising focuses on that clue. Quote Link to comment Share on other sites More sharing options...

Mike Petree Posted May 7, 2022 Share Posted May 7, 2022 One of the weirdest motors I've ever seen. I wish I had taken notes about the electrical layout when I did this video. 11 hours ago, Jim Kovar said: Maybe a bear will tell me? 2 Quote Link to comment Share on other sites More sharing options...
Mike Petree Posted May 7, 2022 Share Posted May 7, 2022 p.s. I think left hand pitched the blade was borrowed from my Eck tank motor. Quote Link to comment Share on other sites More sharing options...
Steve Rockwell Posted May 7, 2022 Author Share Posted May 7, 2022 Very Cool to see that in action, Thank You Mike! ...

Steve Rockwell Posted May 8, 2022 Author Share Posted May 8, 2022 (edited) Back to A.C. ..... About Alexander Bernstein himself, reliable information seems a bit scarce... There's plenty about the Bernstein Lamps, patents are easily located, but the customary civic records i.e. census and directory listings are extremely limited. His age, even origin, is given conflicting accounts, though I choose to believe the patent ascriptions and believe him to be the Alex. Bernstein originally from Prussia, and likely born about 1850 or shortly before then...?. He lived in Berlin, London, New York and Boston, but so far I don't have much, and I haven't yet tried overseas sources... A Dr. Bernstein returned to the States about 1896 and delivered at least one lecture dealing with (see US552681) treatment of milk. All listed patents prior to 1890 deal with electrical matters, and I believe them all, English & US alike, as being from the same inventor, who likely traveled a great deal... The single most interesting factoid to me has been the situation described in the two excerpts; the first, from the Journal of the Franklin Institute, Jan 1887, and the second is Bernstein's account of the matter. What most intrigued me about this is the co-incidence of Bernstein (attempting to patent AC transmission while working on his Bernstein [Boston] lamps) and William Stanley Jr. (working in Boston on lamps for Swan) both being in Boston concurrently, where they very possibly rubbed shoulders at the electrical society and..... ¿discussed electrical matters? Imagine if Bernstein's work is what led Stanley towards AC transformation and transmission, over which he and Team Westinghouse eventually triumphed (and profited)... As I said, the possibility intrigues me..... Edited May 8, 2022 by Steve Rockwell Quote Link to comment Share on other sites More sharing options...
