ABSTRACT:
A bail assembly for a rope drive mechanism is described which operates to equalize the loads on the ropes extending through it and minimize bending of those ropes. Two ropes are looped through the bail around small sheaves which are rotatably mounted on a double eccentric shaft. The ropes are guided to and from the sheaves in the same plane. The bail assembly is mounted to align itself with the plane of the ropes, and it is balanced so that its weight will not bend the ropes under slack conditions. Provisions are made for the bail assembly to operate to remove slack in the ropes by exerting its weight on the ropes.
