Abstract
In a drive system for an overhead conveyor, a first drive shaft presents a path of travel for a trolley, and a second drive shaft spaced from the first drive shaft provides a continuation of the path of travel. A flexible drive cable spans the gap between the shafts and interconnects the terminal end of the first shaft with the receiving end of the second shaft to transfer torque thereto to rotate the second shaft. The cable comprises spiral wound strands joined together to preclude unraveling thereof and thus the second shaft may be driven by the first shaft when their longitudinal axes are not collinear.
