Spanish Utility Model # 114,146

Spanish Utility Model 114,146 - Zeus main image

This is a registration for a ‘Utility Model’ - a kind of patent-lite. It relates to some aspect of the chain tensioning device in a derailleur. Given the date of 1965 it could possibly cover the move to an offset pivot point for the derailleur cage - mirroring Campagnolo’s change from the Gran Sport to the Record.
