Abstract: The specification describes an improved slack adjuster for application especially to air brakes on trucks in which all adjusting mechanism is contained entirely within the slack adjuster body, the slack adjuster mechanism within the body comprising, a driven ring adapted to be driven by a splined actuator and rotatable within a body drive ring, the driven ring having drive and reverse ratchet means and pawl means within the body ring meshing with the ratchet means of the driven ring for transmission of torque from the body ring to the driven ring, a separate slack ring rotatable within the body ring through a predetermined angle and having an anchor arm extending exteriorly of the body for connection to a rigid anchorage; a further adjuster ring is freely rotatable about the actuator shaft within the slack ring through a predetermined angle; ratchet means on the adjuster ring mesh with the ratchet means of the driven ring; and a compression spring urges the ratchet means of the adjuster ring and the driven ring into meshing relationship.
