Adjustable width rotary finishing tool

Abstract

Abstract THE ADJUSTABLE WIDTH ROTARY FINISHING TOOL COMPRISES A CARRIER OR HUB MADE FROM A PLURALTIY OF DISCS OR ELEMENTS ARRANGED IN SIDE BY SIDE ABUTTING RELATIONSHIP. THE HUB INCLUDES A PLURALITY OF CIRCUMFERENTIALLY EXTENDING ENDLESS GROOVES OR CHANNELS IN THE OUTER SURFACE OF THE HUB. THE HUB INCLUDES ANNULAR RIMS ADJACENT THE GROOVES, WITH THE GROOVES AND RIMS BEING FORMED BY THE DISCS. A PLURALITY OF RADIALLY SPACED OPENINGS EXTEND LONGITUDINALLY THROUGH THE RIMS AND THE END SURFACES OF THE HUB, EACH OPENING BEING DEFINED BY A SERIES OF ANNULAR BVEARING POINTS. A PLURALITY OF GENERALLY RADIALLY EXTENDING FINISHING FLAPS ARE PROVIDED WITH RETAINER MEANS ON THE INNER ENDS THEREOF WHICH EXTEND INTO THE GOOVES OF THE HUB IN ALIGNMENT WITH THE CORRESPONDING BEARING POINTS. PIVOT PINS EXTEND THROUGH THE OPENINGS AND THE RETAINER MEANS OF THE FLAPS. WITH SUCH A CONSTRUCTION THE FINISHING FLAPS AND CORRESPONDING PINS ARE ARRANGED TO PIVOT THROUGH A SMALL PREDETERMINED ANGULAR MOVEMENT TO HELP MAINTAIN THE WHEEL IN PROPER BALANCE. THE LENGTH OF THE HUB MAY BE INCREASED BY ADDING DISCS TO THE HUB OR THE LENGHT MAY BE DECREASED BY REMOVING DISCS FROM THE HUB.
