<p>COMPRESSION TYPE RAILROAD BRAKE SLACK ADJUSTER A railroad slack adjuster has a threaded adjusting screw, one end of which is adapted to be connected to one portion of a railroad car brake rigging. The slack adjuster also has a clutch housing assembly, telescopic with the adjusting screw and adapted to be connected to another portion of the brake rigging. A clutch disk is rotatably mounted on the adjusting screw for engagement with opposing clutch surfaces within the clutch housing. A trigger housing is telescopically positioned about the adjusting screw, clutch housing and clutch disk. A spring is positioned about the adjusting screw and effective between the clutch housing and adjusting screw to urge the screw outwardly of the clutch housing. There is a further trigger spring positioned about the clutch housing and urging the clutch housing outwardly of the trigger housing. A brake application applied at opposite ends of the slack adjuster to the adjusting screw and clutch housing causes the clutch disk to move between the opposing clutch surfaces as the slack adjuster lets out and takes up slack in the brake rigging during application and release of the brakes.</p> |
