Abstract: An engine clutch control mechanism which incorportes a flexible remote control cable comprising a core (1) which is axially displaceable within a conduit (2), is provided with a self-adjustment means for compensating for clutch wear. The self-adjustment means comprises a conduit-anchoring device (14) for anchoring the conduit (2) to an abutment (5) held by a fixture (4). When the conduit-anchoring device is in its operative position it makes tooth engagement with the conduit. The conduit-anchoring device is connected to the core (1) via a yielding coupling (12) so that the said device (14) is displaced into conduit-engaging position by force transmitted to it from the core during an initial part of the operative stroke of the core. Following anchorage of the conduit to the abutment (5) the operative stroke of the core continues to completion.

Abstract: A self-adjusting engine clutch control cable comprising a movement-transmitting core (1) sliding within a guiding conduit (2) is provided with a self-adjustment device comprising a clamp (3) for releasably connecting one end portion of the conduit (2) to an abutment (4). A clamp component (5) is connected to one end portion of the conduit (2) by a slip-coupling (9). When a load (29) is applied to the core (1) by depression of the clutch pedal, movement of that end portion of the conduit is transmitted to component (5) via the slip coupling. Jaw elements (17,18) of that component (5) close onto that conduit portion while permitting it to advance in the clamp against biasing spring (27). On its release, that conduit portion moves back to a position depending on the action of spring (27) and on any end-of-cycle cable loading imposed by the clutch clamping spring as a result of clutch wear.
