ABSTRACT:
A clamp is provided for securely aligning opposed longitudinal halves of a pipe. The clamp comprises a support having a recess therein for receiving a portion of the pipe. First and second levers are pivotably mounted to the supports on generally opposite sides of the recess therein Each lever includes opposed gripping and actuating ends. A piston and cylinder assembly extends between and is pivotally connected to the actuating ends of the first and second levers. As a result, the movement of the piston relative to the cylinder causes the sequential rotation of the first and second levers about their respective pivotable mountings to the support, to securely urge the gripping ends thereof into contact with the pipe mounted in the recess of the support.
