Abstract
A biscuit jointer cutter for making segment shaped cuts by plunge cutting has a shoe assembly reciprocally movable relative to a housing containing a motor. The shoe assembly houses a cutter blade rotatably driven by the motor, and has a front opening through which the blade is movable in a forward direction for cutting and retractable in a rearward direction after cutting. A fence assembly is mounted on the shoe assembly above the front opening. The fence assembly is adjustably movable upwardly and downwardly relative to the front opening by means of a rack and pinion mechanism, and also has a fence adjustably pivotable through 90 degrees. A depth of cut adjustment mechanism is operatively connected between the shoe assembly and the housing, and includes a movable rod cooperative with a stop. The stop is a turret selectively rotatable about an axis eccentric of the rod and having recesses of different axial length. A single spring surrounds the rod and functions to both bias the blade to retract and to yieldably latch the turret stop in selected positions. The shoe assembly has a pivotally attached shoe to expose a blade chamber and the blade.
