Polygon box tools applied to automatic screw machines

A polygon box tool comprising:

• a main housing,
• a cam shaft in said main housing which is driven by a drive means,
• a cam secured to said cam shaft,
• said cam including first and second grooves in one face of said cam, said first groove in said cam being formed in said cam at a greater radial dimension than said second groove in said cam face,
• a front housing,
• axially aligned first and second transverse slides in said front housing in parallel relationship with each other with said first and second cam grooves facing said transverse slides,
• a first cam follower pin extending from said first transverse slide and extending into said first cam groove for reciprocating said first transverse slide perpendicular to the axis of the tool,
• a second cam follower pin extending from said second transverse slide and extending through said first transverse slide into said second cam groove for reciprocating said second transverse slide,
• means for securing a first cutting tool on said first transverse slide for reciprocating movement therewith, and
• a second means for securing a second cutting tool on said second transverse slide for reciprocating movement therewith,
• whereby said first and second cutting tools perform work on a piece of material simultaneously.
