Patent ID: 7930960

Claim:
A universal machinery fence system for a work table of a workpiece material removal machine, comprising: a rail defining a guide track, the rail being attachable to the work table of the workpiece material removal machine having a material removal tool, wherein the rail includes an angled surface that faces downwardly and extends the length of the rail and an opposing surface opposite the angled surface that also extends the length of the rail, wherein a cross-section of the rail between the angled surface and the opposing surface is thinner at a downward portion of the cross-section of the rail than at an upward portion of the cross section of the rail as measured horizontally from the angled surface to the opposing surface; a clamp block positionable along the rail, wherein the clamp block includes a mating angled surface that faces upwardly and is configured to mate with the angled surface of the rail wherein a profile of the mating angled surface of the clamp block matches a profile of the angled surface of the rail in a complimentary fashion; a fastener for securing the position of the clamp block along the rail, the fastener including a mating opposing surface facing the mating angled surface of the clamp block, wherein the mating opposing surface of the fastener is configured to mate with the opposing surface of the rail when the mating angled surface of the clamp block is mated with the angled surface of the rail, wherein tightening the fastener bears the mating opposing surface of the fastener against the opposing surface of the rail and draws the mating angled surface of the clamp block towards the angled surface of the rail such that the upwardly angled surface of the clamp block is pulled against and forced into abutment with the complimentary downwardly angled surface of the rail and the downwardly angled surface of the rail slides the clamp block downward and holds the clamp block against the track, wherein loosening the fastener allows the clamp block to be slid along the track and loosening the fastener further such that the mating angled surface of the clamp block can clear the angled surface of the rail allows the clamp block to be lifted off the rail at any position along the rail; and a fence for guiding a workpiece into the material removal tool attached to the clamp block.
