ABSTRACT:
A coupling, supportable by a first and second O-ring belt, has two gear sheaves in mating contact. The inner portion of each gear sheave has a friction surface for mating with one of the O-ring belts. The rotational drive of the first O-ring is imparted to the first of the gear sheaves through the first frictional surface causing the sheave to rotate. The rotation of the first sheave then causes the second sheave, through the mating gears, to rotate in a direction opposite the direction of the first gear sheave. The frictional surface of the second sheave then imparts the rotation of the second sheave to the second O-ring. In this manner the rotational drive of the first O-ring is reversed when transmitted by the second O-ring as said O-rings support said sheaves.
