ABSTRACT:
A threaded rod (40) extends through two blocks (20, 22). Each block (20, 22) has a bore. The bore of the first of the two blocks (20) is not threaded and is prevented from moving when the threaded rod is turned. The bore of the second of the two blocks (22) is threaded and engages the threads of the threaded rod (40). As the rod (40) is turned clockwise or counter clockwise, the second block (22) responds by moving toward or away from the first block (20). One side of each block (20, 22) is connected to a plate (24, 26) which is contoured to fit the inner wall of a tube (11) or pipe. The blocks (20, 22) and plates (24, 26) are pivotally connected by bars (30). A cold welding compound is applied to the plates and the device is inserted into a tube (11) to be repaired. When the plates (24, 26) are aligned over the portion of the tube (11 ) to be repaired, the threaded rod (40) is rotated so that the second block (22) moves toward the first block (20) causing the plates (24, 26) to move outward. The threaded rod (40) is rotated until the device (10) is secured and a firm union between the plates (24, 26) and wall of the tube (11) is achieved.
