Latest update: 8-12-20
Emerson fans are one of the most widely collected, and regarded by many as the best fans ever made. I, for one, have always had a hard time remembering the dates that different models were made. Here I have compiled a list of all of the 60 cycle AC brass blade fans that Emerson made from the earliest 1892 "Meston" until the last of the brass blade models, the 29646 and 71666 models. I have also added the earlier steel blade models that replaced brass in 1931.
A few early models, c.1901, that you are not likely to encounter and which I have never seen have been omitted until I get more information. (Those omitted Types turned out to be 133 cycle motors). The dates given are believed to be accurate but some errors may have crept in. I would like to update the list where possible if readers will let me know any additional or corrected information.

* steel blades replaced brass in 1931
Type Years made
M1 (Meston) 12" desk fan 16,000 alternations (133 cycles)
M2 (Meston) 16" desk fan, 16,000 alts
1895-96 "Emerson Electric" Alternating Induction Fan Motor (not a Meston but motor is so marked on the front plate) Has rear switch, no brushes or commutator (mostly bronze motor cases)
1897 "Emerson Electric" Induction with cast iron motor case and rear switch
1898-1901 style tripod desk fans as follows:
EI-1 16,000 alts (133 cycles) 16" fan
FI-2 7200 alts. 16" fan
EI-2 16,000 alts, 15" fan for 16,000 alts only on c.1895-96 motors.
710*, 711*, 720*, 721*, 810*, 811*, 820*, 821* (1902-04), all are 133 cycles and most are rarely seen.
1220, 1221 (1903-05) 16" S&T, 1221 is a bracket fan (1210, 1215 were these made?)
(For fans listed below the first two digits are the series, the middle digit is the frequency (0 for DC, 2 for 25 cycles, 3/30 cycles, 4/40, 5/50, 6/60 cycles), the fourth number is the number of blades and the last number is half of the diameter of the blade (5 is a 9" blade on brass models but a 10" fan on later models, probably that use steel blades). Note: only 60 cycle models are listed below but other frequencies were made in most Types.
30648 (1922 only) Non-oscillator
72646 (1938-41), replaced 28646, non-oscillator
73646 (1937-41), 73648 (1928-1939), 73668 (1928-1935) Oscillator
Notes: (from discussions with Bill Voigt and other sources)
Force Feed lubrication added to all 12" and 16" Parker and overlapping blade models in 1937
15. First carrying handles on top of motor on 12" and 16" models in 1917 for oscillators, not sure about stationary.
16. 12xxx and 16xxx power cord came out back. c.1915 headwire outlet on base and power cord inlet moved to 45 deg. to right of center for better headwire routing when fan is wall mounted.
17. Emerson letter prefixes on motor tags as follows; compiled by Bill Voigt:
53646, 53648 (1912) Non-oscillator, three speeds, step base replaces ornate base, "Trojan"cage badge.
Latest edit: 14-5-19
73045 (1938) 10" oscillator
78045 (1938) 10" non-oscillator
-12" and 16" fans have more or less cylindrically shaped motors after the 27xxx models.
-The last "trunnion" mounted motors were the 19xxx models.
