Abstract

A clutching device comprising a generally cylindrical tubular slipper having a friction surface, a bearing surface, and first interlocking member. The bearing surface has radial projections which form axially oriented recesses. A generally cylindrical coupling member has a mounting surface, a bearing surface and a second interlocking member. The bearing surface has radial projections which form axially oriented recesses such that the tubular slipper recesses and the coupling member recesses form pockets in which said rollers are located. The tubular slipper and coupling member are axially displaceable relative to one another between a first position wherein the first and second interlocking members are engaged such that the coupling member and the tubular slipper recesses are maintained in alignment and a second position wherein the first and second interlocking members are disengaged and the coupling member and the tubular slipper are free to rotate relative to one another such that the coupling member and tubular slipper recesses are misalignable.
