Abstract
A slider has a drum with alternating alpha and beta grooves, first stacked pulleys, and second stacked pulleys. First and second end pulleys are at opposite ends of the slider. A line wraps as a loop from the last beta groove, around the first end pulley, to the last alpha groove, back and forth around the first stacked pulleys, off the first alpha groove, around the second end pulley, to the first beta groove, back and forth around the second stacked pulleys, and back to the last beta groove. When the drum or the end pulleys are driven, the difference in circumferences of the grooves causes the slider to move toward one of the first or second end pulleys.
