Abstract: Clamp for pressing a workpiece to a miter square and advancing the workpiece through a saw or the like. The clamp comprises two spanning arms and two other arms pivotally joined in a four-sided structure such that, if the arms comprise two pairs of equal length arms, the clamp comprises a parallelogram. One of the short arms is upstanding and pivotally mounted to the miter square. An opposite arm has secured thereto a foot for engaging the workpiece and a handle for pressing the foot against the workpiece through lever action while simultaneously pushing the workpiece toward the saw.
