Abstract 1,234,070. Cycle change-speed actuating mechanisms. FICHTEL & SACHS A.G. 10 Oct., 1968 [14 Oct., 1967], No. 48039/68. Heading B7E. A cycle change-speed actuating mechanism comprises a lever 1 pivoted to a support plate 8 which is attached by lugs 10, 11 to a clip 12 adapted to encircle a tubular frame member, the plane of the support member bisecting longitudinal said clip. A plastics housing 3, consisting of two shell parts 5, 6 defining a slit therebetween, are screwed to the plate 8. An operating cable 21 is connected with the lever, the latter pivoting about a rivet 9. The lever is held in any of three positions by a ball 14, located in a lever bore 15, and adapted to engage one of three bores 16 in the plate 8 corresponding to the gear ratios. A spring 17 resiliently urges the ball 14 towards the bores 16, and its free end 18 acts as an indicator by co-operating with index marks on the housing.
