Abstract
A clutch mechanism connects a rotating shaft to an outer clutch member having a clutch keyway. The clutch mechanism permits the shaft to rotate in a normal direction and prevents the shaft from rotating in a reverse direction when the outer clutch member is rotationally fixed to the housing. A key is moveable into an engaged position with the clutch keyway to rotationally fix the outer clutch member to the housing. The key is also moveable into a disengaged position to permit the outer clutch member to rotate relative to the housing. Thus, the shaft is permitted to rotate in both the normal direction and the reverse direction. A positive, mechanical and/or visual indication of whether the shaft is capable of operating in both directions may also be included. The assembly may include a sealed interior space in common with the machine including the shaft.
