ABSTRACT:
A main body is provided including a first side moveable laterally toward and away from an elongated member to be turned. The first side includes a pair of outwardly projecting arms whose base ends are pivotally supported from the body for swinging movement of the outer free ends of the arms toward and away from each other and the free arm ends include idle rollers journalled therefrom. A drive roller is journalled from the body inwardly of the first side thereof and elongated flexible drive member structure is trained about the drive and idle rollers. The reach of the drive member structure extending between the sides of the idle rollers remote from the drive roller is inwardly deflectable between the idle rollers when the free ends of the arms are swung apart by engagement of the elongated member to be turned with the drive member structure upon movement of the body toward the elongated member and the inwardly deflected reach of the drive member structure is tensioned about the elongated member when the free ends of the arms are swung toward each other to position the idle rollers on the side of the elongated member remote from the drive roller.
