ABSTRACT:
A boiler pipe assembly tool that has separate one-piece gripping jaws engaged with the pipe sections or tubes to be connected, an operating lever and short flexible chains connecting the lever and jaws to move adjacent ends of the tube sections into aligned relation and into engagement with an interposed chill ring used to provide resistance necessary to allow the tool to function in the alignment of and welding of the tube sections. The separate gripping jaws include a structure enabling the point of connection of the chains to be adjusted thereby varying the force moment arm on each jaw.
