Abstract: A MOTOR VEHICLE INCLUDES A TRANSVERSELY EXTENDING HINGED COWL PANEL ADJACENT THE LOWER EDGE OF THE WINDSHIELD FOR CONCEALING THEREBELOW THE WINDSHIELD WIPER ARMS AND BLADES WHEN PARKED. THE HINGED COVER OR COWL PANEL IS MOVABLE FROM A CLOSED POSITION WHEN THE WIPER ARE PARKED TO AN OPEN POSITION WHEN THE WIPERS ARE OPERATING. A FLUID PRESSURE WINDSHIELD WIPER MOTOR OSCILLATES THE WIPER ARMS AND BLADES THROUGH A LINKAGE TRANSMISSION. THE MOTOR INCLUDES AN AUXILLARY LINEARLY RECIPROCATING DRIVE SHAFT FOR MOVING THE COWL TO OPEN POSITION WHEN THE WIPER MOTOR IS STARTED BEFORE THE ARMS AND BLADES MOVE OUT OF PARKED POSITION AND TO CLOSED POSITION WITH THE WIPER MOTOR IS SWITCHED OFF FOLLOWING MOVEMENT OF THE WIPER ARMS AND BLADES TO A DEPRESSED PARK POSITION. THE LINERALY RECIPROCATING DRIVE SHAFT IS COUPLED TO THE HINGED COWL PANEL THROUGHT A RELEASABLE COUPLING ASSEMBLY WHICH CAN BE UNCOUPLED TO PERMIT MANUAL MOVEMENT OF THE COWL PANEL TO AN EXTREME OPEN DETENT POSITION FOR ACCESS TO THE EQUIPEMENT STOWED THEREBELOW. THE COUPLING ASSEMBLY IS PROVIDED WITH AN INTERMDIATE DETENT POSITION FOR RETURNING THE COWL TO A POSITION TO PERMIT WIPEROPERATION IN CASE OF FAILURE OF THE COWL RETRACTING MECHANISM.
