Beschreibung
Zusammenfassung:	A board-engaging device for saws and the like, designed to laterally urge boards toward a fence or guide during ripping and similar operations where it is necessary that each board move in a straight path for accuracy. Inclined rolls at opposite sides of the rotating tool element frictionally grip the board and hold it toward a stationary guide or fence. The rolls are vertically movable, being biased toward a work table by springs or other similar biasing devices. They can be pivoted on an attachment assembly selectively mounted to the table surface of the tool, or can be alternately mounted in a permanent fashion directly upon the table.
