Abstract: A workpiece indexing and clamping system for machining the workpiece. Spherical or narrow cylindrical heads of index pins extend from holes in a base plate into workpiece holes to align and index the workpiece. The pin portions in the base plate holes can be expanded to lock them to the base plate. Each pin has relief flats parallel to the pin axis. Clamps engage workpiece edges with thread-like angled grooves on a cam surface to force workpiece edges against the base plate during machining of the workpiece. A central clamp has a pin extending from the base plate into a workpiece hole. Angled grooves in a cam surface are brought into contact with the hole sides to force the workpiece toward the base plate and hold the central area in place during machining.

Abstract: An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is accomplished by the rotation of a pair of pinion gears each of which engages a respective rack on the movable rails. The simultaneous rotation of the pinion gears is the result of both pinion gears being secured to a common pinion shaft which is rotatably secured to the machine tool. The telescoping nature of the rails allows for adjustment of the fence beyond the working surface of the machine tool.

Abstract: A locking fence for a power tool such as a chop saw, or for a work surface of a workbench, is capable of being moved to a selected location on the chop saw base or work surface and oriented at a selected angular orientation relative to the chop saw blade. The fence is locked simultaneously in such location and orientation when an operator rotates a cam actuator to lift a first clamping member away from the fence, which in turn draws a second clamping member into clamping engagement with the underside of a workpiece support of the base, and which further forces a cam portion of the actuator against the fence. No tools are required to lock or unlock the fence. The fence defines an arcuate slot for enabling the angular orientation to be adjusted. The arcuate slot is maintained in juxtaposition to a slot formed in the work surface for enabling movement of the fence to its selected location on the workpiece support or work surface, by linking screws linking the slots.

Abstract: Disclosed herein is a universal precision positioning jig for woodworking and other operations that is of lightweight and efficient design and that has micro positioning capability. The disclosed positioning comprises a carriage riding on elongated planar bearing plates on a fixed base. Two bearing plates are located at 45.degree. angles on one side of the base and are used in conjunction with a positioning mechanism located on an opposite side of the base for clamping the carriage to the base.

A hinged swing rack mounted to the base engages a toothed rack on the swing rack with a toothed rack on the base, and is clamped into the engaged position using primary and secondary clamping levers. The secondary clamping lever is used to sustain general positioning of the carriage while allowing micro positioning.

Abstract: Stabilizing apparatus for controlling the position of a workpiece relative to a tool. The stabilizing apparatus includes an elongated base for attachment to the tool, an elongated adjustable support that is essentially parallel to the base, and an interconnecting structure that enables the adjustable support to move relative to the base. When a workpiece moves toward the tool, it displaces the adjustable support toward the base thereby compressing springs in the interconnecting structure. This produces a clamping force against an opposed work support surface that stabilizes the position of the workpiece transversely to the direction of travel but allows movement along the work path. Multiple stabilizing apparatus can be used to provide both vertical and horizontal clamping forces.

Abstract: A woodworking fence includes a dovetail slot into which a stop block and a push fixture each having a dovetail protrusion are in slidable engagement. Operation of a thumbscrew extending through the stop block wedges the block protrusion into firm fixed engagement with the fence dovetail slot.
