An improved clutch and brake unit in combination with a rotatable flywheel, the clutch and brake unit having a housing assembly forming a reservoir chamber around a portion of the drive shaft of a machine and surrounding the clutch and brake unit which permit the housing assembly, clutch and brake unit, and shaft to be removably secured as one unit to the rotatable flywheel. A universal coupling is also disclosed, used in combination with an output shaft of a drive assembly and an extension shaft of a driven assembly, comprising radially outwardly extending flanges at the adjacent ends of each shaft, a mating boss on one shaft matable into a recess in the other shaft to dispose the shafts such that the flanges are adjacent one another, a key inserted in a transversely disposed keyway disposed in part within each shaft, a retainer to hold the shafts together at the flanges and retain the key and securement to secure the retainer to the shafts. |
