Abstract
An apparatus providing a substantially fixed length cable drive comprises a motor-driven capstan having a helical groove. The groove on the capstan is sized to receive opposite ends of a cable for simultaneously letting out and taking up the cable. The cable passes over a fixed pulley and is attached to a carriage at a point intermediate the capstan and pulley. The carriage is guided along a rail defining a fixed mass path. The section of cable between the carriage and pulley is parallel to the mass path. The cable ends on the capstan are disposed on opposite sides of a plane containing the parallel cable section during travel of the carriage along the mass path.
