Abstract
Abstract INDEXING DEVICE FOR POSITIONING CUTTER BEARING SPINDLES IN A PLANER-TYPE MILLING MACHINE. EACH SAID SPINDLE IS MOUNTED ON A ROTATABLE INDEXING MECHANISM WHICH TURNS A CUTTING ELEMENT ON SAID SPINDLE TO A PREDETERMINED NUMBER OF COMPASS SETTINGS RELATIVE TO THE AXIS OF SAID SPINDLE. THE INDEXING MECHANISM IS CHARACTERIZED BY A COUPLING HAVING A FIRST PART ROTATABLE IN ONLY A SINGLE DIRECTION, AND A SECOND PART ROTATABLE IN TWO DIRECTIONS. THE ROTATION OF THE SPINDLE IS EFFECTED BY SAID COUPLING WHICH IN TURN IS ACTIVATED BY AN HYDRAULIC CYLINDER.
