Adjustable drive chain saw woodworking machine

Abstract

A woodworking machine includes an adjustable table for holding a workpiece thereon and a drive chain saw spaced from the table and having cutting teeth on one edge and drive engaging chain guides adjacent an opposite edge. The drive engaging chain guides engage a drive wheel driven by a motor. A support plate is positioned above the table and has a plurality of slots therein for adjustably mounting a plurality of roller guide elements positioned to engage both sides of the drive chain saw. Each of the roller guide elements includes at least one groove in an outer periphery thereof and the drive chain saw includes circular chain guides which mate with the groove. Threaded pins are provided for adjusting the position of each of the roller guide elements to engage the drive chain saw whereby a portion of the drive chain saw is formed into an undulating shape to cut curved surfaces in the workpiece when the drive chain saw and the workpiece come into contact. The device further may include a plurality of profile cutting bits mounted on the drive chain saw at a position spaced inwardly from the cutting teeth. The cutting teeth are separated by guide pieces.
