Abstract
A drive shaft coupling apparatus which includes a first segment of a drive shaft, a ferromagnetic end piece mounted on one end of the first segment to provide linear play and angular flexibility with respect to the axis of rotation of the first segment, a second segment of said drive shaft, a motor for driving one of the segments of the drive shaft, a second end piece for providing a magnetic field which is mounted on one end of the second segment to provide linear play and angular flexibility with respect to the axis of rotation of the second segment, and insert for frictionally coupling the end pieces, the end pieces and the insert for frictionally coupling being arranged and dimensioned to provide a magnetic force between the end pieces sufficient to attract one end piece to the other end piece to gradually increase the rotational speed of said one end piece until it reaches the same speed as said other end piece, but insufficient to overload the motor and prevent it from turning.
