Abstract

1430172 Slack-adjusters for internal shoedrum brakes GIRLING Ltd 24 May 1974 [16 June 1973] 4229/75 Divided out of 1430171 Heading F2E The disclosure is almost identical with that of Specification 1,430,171 from which this Specification is divided, but the claims are concerned with an adjuster (for internal shoe drum brakes) of the kind adapted to adjust the spacing between non-actuated ends of a pair of arcuate shoes (1, 2), and comprising a housing (12) adapted to be mounted on a backplate (3) between non-actuated shoe ends, a screw-threaded assembly (16, 19) located within the housing and adapted to act on the said shoe-ends, and adjusting means (25, 28, 29) for increasing the effective length of the assembly to compensate for wear of the shoe friction linings, the adjusting means comprising a worm (25) meshing with the screw-threaded assembly and rotatable within the housing, an adjuster member (28) rotatable relative to the worm in the application of the brake from an initial datum position and coupled thereto by a clutch plate (29) keyed to the worm and relative to which the adjuster member (28) is rotatable in one direction, resilient means (31) for urging into engagement inter-engaging teeth in adjacent faces of the adjuster member and the clutch plate, the space between adjacent pairs of teeth corresponding to braking clearances, and energy-storing means (43) for returning the adjuster member to the initial datum position at the termination of the brake application, the adjuster member (28) rotating the worm (25) to increase the effective length of the assembly (16, 19) if the movement of the adjuster member with respect to the clutch plate has exceeded the spacing between adjacent teeth. The reference numerals in parentheses in the above paragraph relate to Figs. 1 to 3 of the Specification referred to.
