<p>A tool (10, 60, 140) used in joining the adjacent ends of pipes (12, 14, 62, 64, 142, 144) and the like including a structural arrangement which is capable of moving the ends of the members to be joined towards and away from each other, transversely in relation to each other for alignment and adjusting the angular relation of the adjacent ends to accurately, positively, quickly and easily position adjacent ends of pipe members and the like in optimum desired relation for joining the members by welding. The tool includes a plurality of circumferentially spaced lugs (28, 80, 106, 158) mounted on each member to be joined in spaced relation to the end thereof with the ends being secured in place by a clamp structure (16, 18, 68, 70) or the like with the lugs being interconnected by turnbuckle structures (20, 72, 156) having radial screw threaded members (44, 122, 164) at each end thereof with manipulation of the turnbuckle structures and radial screws enabling the adjacent ends of the members to be joined to be oriented in optimum position for welding.</p> |
