French Patent # 868,074 - Selectic

French Patent 868,074 - Selectic main image

This is the first of three patents that, I believe, lead up to the design of the 1950 Selectic derailleur. This derailleur was a 3-speed device with no lever or cable - you operate the derailleur by back-pedalling.

This first patent, from 1940, describes a single pulley device. The patent lists the inventor as Ange Henri Le Beguec of Rennes, France.
