Telechron Motor Nameplates with Serial Numbers

We present this data to help us organize information about Warren Clock Co. and early Warren Telechron Co. clocks. Early clocks have a serial number on the motor nameplate, and we guess that the company stopped using serial numbers around 1930.

Nameplate serial number 2165 from a type A motor
Above: Earliest Warren motor nameplate yet observed, SN 2165.
Nameplate serial number 56967 by Warren Clock Company
Above: latest Warren Clock Co. nameplate, SN 56,967.
Nameplate serial number 59430 by Warren Telecnron company
Above: earliest Warren Telechron Co. nameplate, SN 59,430. The dial on this clock is labeled Warren Clock Co., so it is a transition piece dating to right around 1926.
Nameplate serial number 48948A
Nameplate SN 142,845A
Above: Nameplate SN 142,845A with N.P. 34039 on left and N.P. 100 on right. (Courtesy of Andy Niehaus)

Note: My files did not include a patent from Oct. 3, 1923, a date used on nameplates in the early 1920s. I believe this patent date was used in error, and the Oct. 3, 1922 date was the correct date that should have been used.
