Abstract

454,478. Change-speed gears. BLANCHARD, C., 67, Rue Antoine Durafour, St. Etienne, Loire, France. Jan. 30, 1936, No. 2851. Convention date, Feb. 1, 1935. [Class 80 (ii)] [See also Group XXXI] Mechanism for shifting the chain of a bicycle change-speed gear comprises a bracket 7, carrying the jockey pulley 8 and the tensioning- pulley 13, which slides in an inclined guide slot 5 in a horizontal table or base 4 adjustably secured to the frame member 2. The bracket 7 is actuated by a push or pull from a rod 16 to slide in the guide slot 5 and by its axial movement with respect to the sprockets to shift the chain from one to another to effect the desired change of speed.
