Woodworking machine

A woodworking machine for working at least one side of a workpiece, of a type having a feed table including a working surface, a lower tool spindle for disposing at least one tool projecting from the working surface of the feed table, an upper tool spindle disposed spaced from and parallel to the lower tool spindle for carrying at least one further tool, and bearing means accommodated in each of two bearing housings for supporting each of the tool spindles at one end thereof, wherein the improvement comprises:

• two further bearing housings;
• further bearing means accommodated in each of said two further bearing housings for supporting each of said tool spindles at the other end thereof;
• a removable and interchangeable lower woodworking unit formed by said lower tool spindle and two associated ones of said bearing housings;
• a removable and interchangeable upper woodworking unit formed by said upper tool spindle and two other associated ones of said bearing housings;
• means for displacing at least said lower woodworking unit laterally;
• means for positioning at least said lower woodworking unit vertically relative to said working surface;
• a track bed disposed on said feed table at right angles thereto;
• carrier means including a track disposed slidingly in said track bed;
• means for connecting said lower woodworking unit to said track so that said lower woodworking unit is laterally withdrawable from said machine;
• drive means secured to said carrier means for driving said lower woodworking unit;
• a third spindle disposed between said track and said track bed;
• actuating means situated at one end of said third spindle for laterally displacing said lower tool spindle relative to said upper tool spindle;
• a graduated scale attached to said machine;
• indicator means disposed on said carrier means for reading a lateral position of said lower tool spindle on said scale;
• an eccentric shaft disposed between said track and said track bed;
• and
• a lever connected at right angles to one end of said shaft so that a spacing of said track from said track bed is variable by a few hundredths of a millimeter for vertically positioning said lower woodworking unit relative to said working surface.
