(under subclass 86) Device including means to limit the movement of one jaw with respect to an opposed jaw so that work-engaging or work-gripping faces of the respective jaws are maintained continuously normal to the line of relative jaw movement.
(1) Note. While most of these devices are for flat faced jaws, the subclass is not so limited. Configured jaws with means to maintain the relative spatial orientation, as set forth above, are classified here.
