Boiler wall tube tool

A boiler wall tube tool comprising a pair of opposed clamp members with each clamp member including a pair of recesses therein to engage adjacent ends of a pair of boiler wall tubes on opposite sides of a juncture between the adjacent ends, means moving the clamp members towards each other for secure clamping engagement of the tubes for maintaining them in alignment while connecting the ends of the tubes by welding, each clamp member including a recess in each side edge thereof providing access to the periphery of the juncture between the ends of the tubes clamped by the clamp members, said means moving the clamp members towards each other including a manually pivotal handle structure including eccentric means connecting the handle structure pivotally to one of said clamp members for moving the clamp members towards and away from each other, means adjustably connecting the handle structure to the other of said clamp members to enable variation in the space between the clamp members when in clamping engagement with the tubes.
