L'Auto 5th April 1937 - Huret advert main image

This April 1937 advert contains a trove of interesting pieces of information:

  • The Huret range is now composed of two models, the Huret Course Pro and the Huret Touriste. It is not clear what differentiates them.
  • These can be fitted to the dropout, without clamps or braze-on fittings.
  • One of these models weighs 250g (presumably the Huret Course Pro) - which is not shabby, even by today's standards.
  • They are the only derailleurs trustworthy enough to be used for cyclo-cross.
  • Fascinatingly, they appear to be manufactured for Huret by Chaluret.

This derailleur seems to be operated by a rigid cable that can transmit torque, a bit like the ones later used by Huret to drive its speedometers. This cable appears to be twisted by some unseen control lever to turn a cog that is mounted on its end which, in turn, drives a toothed, sliding, shaft in and out. The pulley cage seems to be mounted on the end of this shaft.

The relevant patent is French Patent # 813,241 which includes some clearer drawings.
