PCT No. PCT/AU95/00530 Sec. 371 Date Feb. 26, 1997 Sec. 102(e) Date Feb. 26, 1997 PCT Filed Aug. 25, 1995 PCT Pub. No. WO96/07569 PCT Pub. Date Mar. 14, 1996A slack adjuster (1) for a cable operated system, such as a brake assembly operable by a brake lever (2), includes two drive parts (9) and (10) which are engageable to form a drive connection between the brake lever (2) and the cable (29) to enable the lever (2) to impart an actuating force to the cable 929) during movement of the lever (2) between a rest and a fully actuated position. The slack adjuster (1) further includes a pivotal lever (23) which is operable to disengage the drive parts (9) and (10) during a predetermined portion of one of either the applied or release strokes of the brake lever (2), but inoperative during other portions of the strokes, thereby enabling adjustment of slack in the cable (29) by movement of one drive (9, 10) relative to the other drive part (10, 9) to occur only during the one stroke. |
