ABSTRACT:
A stop assembly includes a drive arm and a stop arm with a backside configured to direct a reaction force applied by the stop arm to the drive arm when the stop arm engages a workpiece. The drive arm pivots between pre-locked and unlocked positions in response to movement of the reciprocatable member between extended and retracted positions. The motion range includes a locked position between the pre-locked and unlocked positions. The stop arm is pivotally mounted to the body and has a front side for engaging a workpiece, while the backside engages the drive arm. The stop arm backside is configured such that the reaction force has a component normal to the drive arm plane when the drive arm is between the pre-locked and locked positions, and such that the reaction force is substantially coplanar with the drive arm plane when the drive arm is in the locked position.
