Abstract

710,133. Change-speed gearing. LES BREVETS SOUHART SOC. ANON. Oct. 15, 1951 [Oct. 16, 1950], No. 24035/51. Class 80 (2) A cycle chain is shifted from one to the other of crank sprockets 2, 3 by a fork 5 carried by a rod 6 movable in a slideway 7, inclined to the crank axis, by a bell-crank lever 13 operable by a cable 14 against the action of a return spring 12. The slideway is formed in a member 9 secured to the upright frame tube 11. The member 9 may be adjustable on the tube 11 and the :slideway 7 may be adjustably mounted on the member 9, the fork 5 then' being hinged to the rod 6.
