Abstract
1528977 Chain shift change speed gear SHIMANO INDUSTRIAL CO Ltd 12 Dec 1975 [12 Dec 1974 (2)] 50960/75 Heading F2D A chain shifter, particularly for use at pedal crank sprockets on a cycle, includes in the transmission between a control cable W and a parallel-link-mounted chain shifter 8, a transmission member 14 which can yield if the chain is unable to make the required movement, e.g. if the pedal sprocket is not rotating. In Fig. 2 the transmission member is a leaf spring 14, attached by screws 15 to one 5 of the parallel links and bearing on a cable-operated arm 12, which swings on a pivot 2 on a frame-mounted fixed member 1, which carries the parallel links 4, 5 of the chain shifter 8 on pivots 2, 3. Application on control tension to the cable W swings the arm 12 counterclockwise, which, through the leaf spring 14, causes the chain shifter 8 to follow in the same direction in opposition to return coil springs 10, 10. If the chain is unable to follow, the shift 8 is detained thereby, and the pivoting arm causes the blade spring 14 to yield. Stops 16, 17 limit clockwise movement of the arm 12 and counterclockwise movement of the link 4. In Figs. 5 to 7, not shown, the transmission member is a rigid plate (14) bearing on a coil spring (11) arranged inside the parallel links 4, 5, and having projecting ends bearing on the pivots 3, 7. In a further modification, not shown, a coil spring is arranged between the arm 12 and the plate 14.
