Mechanism for moving a table lengthwise and crosswise and for turning the table

A mechanism for moving a table means having a table as a part thereof in the lengthwise and crosswise directions and for providing turning movement of the table, said mechanism comprising:

• a support base;
• support bearing means on said support base for supporting the table means during movement in the lengthwise and crosswise directions relative to said support base and during turning movement of the table relative to said support base and for preventing vertical movement of the table relative to said support base;
• two mutually orthogonal pairs of parallel guide faces adapted to be mounted on the table means;
• guide members on opposite sides of the table means and engaged with said guide faces for controlling the movement of the table means in the lengthwise and crosswise directions and for controlling turning movement of the table;
• and
• moving means connected to at least some of said guide members for moving appropriate ones of said guide members for causing movement of the table means along the other of said guide members in the lengthwise and crosswise directions of the table and in turning movement of the table.
