<p>A control cable adjuster device (Fig. 3) includes an end piece 16 fixed relative to a control cable run and an adjuster nut 18 on a threaded portion of the conduit 8. The adjuster nut 18 is biassed away from the end piece 16 by a compression spring 24 to apply tension to the inner core 2 and form an initial gap 30 between the adjuster nut and the end piece. As wear occurs in an associated actuated component (for example, a motor vehicle clutch) so the gap 30 decreases to accommodate the wear. The gap 30 is reset by rotating the adjuster nut 18 to move the adjuster nut along the threaded conduit 8. Rotation of the adjuster nut is effected through teeth 40 meshing with teeth 38 on a sleeve 32, axial movement of which is limited by abutment of a shoulder 44 on the sleeve with a collar 48 on the end piece 16. The various components are dimensioned such that the teeth 38, 40 move out of mesh upon the gap 30 being re-established. The sleeve may be rotated manually or through gearing 58, 60 from a drive 54 which is derived from components associated with the actuated component or is provided by an electrical motor 56. The drive may be energised continuously or intermittently. The device may be positioned in, or at an end of, a cable run and alternatively co-act with the inner core of the cable run. <IMAGE></p> |
