ABSTRACT:
A self-adjusting mechanical cable-control apparatus 6 (FIG. 1) has one end 14 of the cable 1 connected to a pedal 3 by a slotted yoke 17 having a transverse coupling member 22 extending through a U-shaped aperture 21 in the pedal. A tubular spacer 23 of rigid thermoplastics extends co-axially of the cable 1 and co-operates with the yoke 17 and a fixed wall 8 to limit movement of the cable 1 toward a member 4 to be actuated by the influence of resilient biasing spring structure associated with the member 4, thereby defining a rest position unaffected by accidental excessive return displacement of the pedal. A saddle 26 of plastics material having a low co-efficient of friction lines the U-shaped aperture 21 and is connected to the yoke 17 by a spring 33 biassing the pedal 3 toward the yoke 17 and a pedal stop 13. The tubular spacer 33 is dimensioned such that, in the rest position, the transverse coupling member 22 is spaced from the bearing surface of the saddle 26 by a gap e thereby permitting independent setting of the limit positions of the pedal 3 and the member 4 to be actuated.
