Abstract
A shield for use in connection with a workholding apparatus that has a base having a longitudinal slot and at least two jaw members operably supported on the base for selectively clamping a workpiece therebetween. The shield comprises a plate member adapted to be removably received on the base and configured to permit at least one jaw member to move relative thereto. The plate member may be sized to provide the workholding apparatus with a worksurface that is wider than the base, the plate member having an opening to permit movement of the jaw members such that it is completely covered by the cooperation of the jaw members and the plate to prevent debris from entering the longitudinal slot of the base. Alternately, the opening is provided with grooves for slidably guiding a telescoping cover plate which is attached to movable support members and is cooperated with the cover plate to completely cover the longitudinal slot during the clamping operation.
