ABSTRACT:
A rotatable shaft carries a hard plastic disc located in a housing. A braking member in the form of a steel washer is sandwiched between the plastic disc and a washer-like elastomeric spring which is compressed against an axially facing wall of the housing. The spring urges the braking member frictionally against the disc to retard rotation thereof and dampen rotation of the shaft. By adjusting a screw, the disc may be shifted axially toward or away from the spring to change the compression thereof and thereby change the retarding torque applied to the disc.
