Fastener driving apparatus

Abstract

Abstract A FASTENER DRIVING APPARATUS IS DISCLOSED WHICH HAS A FASTENER SENSING MEMBER MOUNTED IN THE DRIVE TRACK TO BE MOVED INTO AN OPERATIVE POSITION BY ENGAGEMENT OF A FASTENER THEREWITH IN RESPONSE TO THE MOVEMENT OF A FASTENER BY A FASTENER FEEDING MECHANISM LATERALLY INTO THE DRIVE TRACK INTO A PROPER POSITION TO BE DRIVEN LONGITUDINALLY OUTWARDLY THEREFROM BY A PNEUMATICALLY OPERATED FASTENER DRIVING ELEMENT. THE APPARATUS INCLUDES A PNEUMATIC CIRCUIT, ACTUATION OF WHICH IS MANUALLY CONTROLLED BY DIGITAL MOVEMENT OF A TRIGGER THE OPERATION OF THE CIRCUIT BEING DEPENDENT UPON THE MOVEMENT OF THE FASTENER SENSING MEMBER INTO ITS OPERATIVE POSITION SO THAT IF NO FASTENER IS PRESENTED ON PROPER POSITION TO BE DRIVEN, THE FASTENER DRIVING ELEMENT WILL NOT BE PNEUMATICALLY OPERATED. THE PNEUMATIC CIRCUIT IS OPERABLE TO RETURN THE FASTENER DRIVING ELEMENT AFTER THE FASTER HAS BEEN DRIVEN THEREBY WITHOUT THE NECESSITY OF DIGITALLY RELEASING THE TRIGGER AND AGAIN OPERATING THE FASTENER DRIVING ELEMENT TO DRIVE ANOTHER FASTENER WHEN THE TRIGGER IS NOT RELEASED THEREBY RENDERING THE APPARATUS CAPABLE OF AUTOMATICALLY DRIVING A SEQUENCE OF FASTENERS AS THE DEVICE IS MOVED ALONG AND AGAINST A WORKPIECE. THE PREFERRED FASTENER FEEDING MECHANISM DISCLOSED IS OPERABLE TO HANDLE A CONICAL CYLINDRICAL FASTENER PACKAGE INCLUDING A MULTIPLICITY OF COMMON NAILS INTERCONNECTED IN SERIES IN PARALLEL RELATION BY A PAIR OF PARALLEL FLEXIBLE FRANGIBLE WIRES WELDED TO THE SHANKS OF THE NAILS AND INCLUDES A FRUSTO-CONICAL SUPPORT MEMBER FOR SUPPORTING THE CONICAL CYLINDRICAL PACKAGE OF NAILS BY ENGAGEMENT OF THE POINTS THEREWITH AND A TURRET MEMBER MOUNTED FOR INCREMENTAL STEP-BYSTEP ROTARY MOVEMENT ABOUT A CENTRAL AXIS PARALLEL WITH THE AXIS OF THE DRIVE TRACK OPERABLE TO FEED SUCCESSIVE NAILS INTO THE DRIVE TRACK AND TO EFFECT SEVERANCE OF THE WIRES DURING THE DRIVING MOVEMENT OF THE NAIL.
