Abstract
A cable passes over pulleys to precisely control the linear movement of a machine element back and forth along a guideway. The cable path connects multiple pulleys on stationary machine elements to multiple pulleys on the movable machine element, affording mechanical advantage to one driven pulley. A particular arrangement and alignment of the pulleys that pull in one direction with the pulleys that pull in the opposite direction cancel extraneous forces and moments and cause the resultant force to act on the center of gravity of the moving element.
