Abstract
A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.
