Abstract
A workpiece-supporting fence has a pair of movable fences movably attached to a fixed fence which is secured to a base of the device in which the fence is being used. The pair of movable fences are located on opposite sides of a working tool such as a saw blade. A fixed clamping arrangement is associated with each movable fence and provides a single point actuation member for each movable fence to clamp the movable fence to the fixed fence such that the movable fence is vertically aligned and flush with the fixed fence. In one embodiment, each movable fence is provided with a gap-filling flap which is pivotably secured to the movable fence to be movable between a lower and an upper position. In its lower position, the gap-filling flap minimizes the gap between the movable fence and the working tool. In its upper position, the gap-filling flap provides additional support when working with taller or thicker workpieces. The workpiece-supporting fence further includes a fence position indicator which allows for the positioning of one or both of the movable fences for providing clearances for a specific miter and/or bevel cut. In addition, the workpiece-supporting fence incorporates a detent system for locating the fence at tone or more of the most popular miter and/or beveling settings.
