Abstract

See full text

A slack adjuster for narrow gauge rail cars including a housing having a body with a first clevis joint, a coupling secured to the body, and a guide tube secured to the body coupling. A lever is pivotally coupled to the housing for moving an actuator coupled to a clutch. The clutch is engaged with the external threads of a rod and moveable between a first captured position, a second position where the clutch is free to rotate, and a second captured position to selectively control movement of the rod. Movement of the lever withdraws the actuator so that the clutch releases and can spin, allowing the threaded rod to translate from the retracted to extended positions. Opposing forces applied to a ram causes the clutch to move to the second captured position, thereby preventing rotation of the clutch and preventing the threaded rod from retracting further into the housing.
