A railroad slack adjuster has a threaded rod, one end of which is adapted to be connected to one portion of a railroad car brake rigging and a tube telescopic with the rod and adapted to be connected to another portion of the brake rigging. A clutch member is rotatably mounted on the rod for engagement with opposing clutch surfaces on the tube. A housing is telescopicaly positioned about the rod, tube and clutch member. There are springs positioned about the tube and effective between the tube and housing to urge the tube inwardly of the housing. There are further springs positioned about the rod and urging the rod inwardly of the tube. A brake application tension applied at opposite ends of the slack adjuster to the rod and tube cause the clutch member to move between the tube opposing clutch surfaces as the slack adjuster lets out and takes up slack in the brake rigging during brake application.
