Power tool fence

An adjustable fence structure in combination with a power tool work table having a flat, horizontal top work supporting surface, forwardly and rearwardly disposed front and rear edges, oppositely disposed inner and outer side edges and longitudinal and lateral axes, said fence structure includes an elongate mounting rail, mounting means spaced longitudinally of the mounting rail and engaging said table to releasably secure the mounting rail on said supporting surface parallel with said longitudinal axis thereof, an elongate fence rail, positioned laterally inward of the mounting rail and having a laterally outwardly disposed vertical inner surface and a flat bottom surface in sliding supported engagement on said support surface, elongate front and rear links with inner and outer ends, the links are equal in longitudinal extent are spaced longitudinally of the rails and are in spaced parallel relationship with each other, coupling means pivotally coupling the inner and outer ends of the links to related front and rear portions of said rails with the longitudinal spacing of the coupling means at the inner and outer ends of the links spaced equidistant, lock means releasably locking the rails and the links against relative pivotal movement with said rails in set lateral spaced parallel relationship and including an elongate bar with inner and outer ends, coupling means pivotally coupling the inner end of the bar to the fence rail in spaced relationship between the inner ends of the links and screw means releasably securing the outer end portion of the bar to the mounting rail at a position spaced between the outer ends of the links with the axis of the bar angularly related to the longitudinal axes of the links and rails, said fence rail has a longitudinally extending vertical inner flange with a longitudinally extending upper edge and an elongate glide with a flat, vertical inner work-engaging flange in supported engagement with the inner surface of the fence rail and a longitudinally extending laterally inwardly and downwardly formed upper edge portion in sliding supported hooked engagement over the upper edge of the inner flange and shiftable longitudinally relative thereto.
