Adjustable fence for a compound miter saw
First Claim
1. A device for performing working operations on a workpiece, said device comprising:
- a motor;
a base supporting said motor;
a working tool drivingly connected to said motor;
an adjustable fence assembly comprising;
a first fixed fence attached to said base, said first fixed fence being disposed on one side of said working tool, said first fixed fence having a first end adjacent said working tool and a second end spaced from said working tool;
a first movable fence being interconnected with said first fixed fence, said first movable fence having a first end engaging said first fixed fence between said first and second ends of said first fixed fence to define a planar workpiece supporting surface;
a first gap-filling flap pivotably secured to said first movable fence, said first gap-filling flap pivoting about an axis generally perpendicular to said planar workpiece supporting surface; and
a first clamp disposed at said second end of said first fixed fence for clamping said first movable fence to said first fixed fence, said first clamp providing the only means for prohibiting movement of said first movable fence with respect to said first fixed fence.

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.
