ABSTRACT:
A swing clamp having a clamp arm pivotally mounted on a rotatable pivot shaft for movement between operative and inoperative positions and with the rotation of the pivot shaft being under the control of a pair of oppositely-acting pistons engageable with a crescent-shaped cam integral with the pivot shaft. Externally adjustable stops control the action of the pistons and limit the forces applied to the pivot shaft. The body of the swing clamp has two sets of passages alternately usable for controlling the direction of operation of the swing clamp and including a relocatable sequence valve.
