Mike Morris Posted July 22, 2024 Author Posted July 22, 2024 Brush inspection ports, I hadn't considered that. Makes a lot more sense, couldn't wrap my brain around more brushes, but had never seen one of these ac/dc and multi frequency fans before. Not surprising they used an existing part for the cap/cover. The vents in the front motor housing like Jim's fan #1 , my fan and Anthony's former fan were deleted and inspection ports added to 2nd generation and beyond. I haven't been able to pin a date on any version of these fans. Other than what Jim and Russ have provided I have found virtually nothing that would date these GEC orbital "gyro" fans other than 1926 and later. Still, I know a lot more than I did a few days ago. Thanks Quote
Jim Dunn Posted July 22, 2024 Posted July 22, 2024 Hi Michael.Going by Russ’s research they are from about 1924 - 1925 onwards and proof of 1927 below Fan No3 has the patent of 24618 and stamped 27 for the year of 1927 I presume. You can see in the 1926 catalogue image of the “Gyro”Patent dates identified 210476, 208530 and 207655. I guess the gyro fans were produced later into the 30’s but sorry I don’t have any documentation of the total timeline. Quote
Michael Bouthiller Posted July 22, 2024 Posted July 22, 2024 Did they make the GEC orbital in different sizes Jim? Quote

Louis Luu Posted July 22, 2024 Posted July 22, 2024 They came in your standard black color and not so rare Ivory. Quote
Jim Dunn Posted July 22, 2024 Posted July 22, 2024 They came in 12 &16 inch, but 16 inch are scarce. Quote

Jim Dunn Posted July 23, 2024 Posted July 23, 2024 I have 1 x 16 inch Gyro and it’s pretty much the identical as the Fan No 1 in the 12 inch with multiple frequencies. 1 Quote
