Abstract
A clutch brake device comprising two concentric ring-shaped plate sections, threadably and adjustably secured together via four screws. The screws pass through the periphery of the exterior plate and extend into depressions on the interior plate. The interior plate has central tangs that engage keyway slots in an input shaft. The outer plate has tabs symmetrically positioned around its outer periphery, wherein the tabs can receive force from a rod, or the like, to move the outer plate relative to the inner plate to facilitate threaded relative adjustment. Each ring-shaped plate has thereon a frictional surface, wherein each frictional surface is dimensionally different from the other. An alternate embodiment comprises a camming member, having two slidably separable plates. The first plate rides up the ramp sections of a second plate, thereby causing the first plate to separate axially from the second plate and, thus, expand the clutch brake.
