Valve operating mechanism

Claim 2

THE COMBINATION OF: A VALVE ASSEMBLY INCLUDING A VALVE STEM, YOKE MEANS, AND DRIVING MEANS SUPPORTED BY THE YOKE MEANS TO BE IN DRIVING ENGAGEMENT WITH SAID VALVE STEM; A DETACHABLE ADAPTER ASSEMBLY INCLUDING ADAPTER MEANS SUPPORTED BY SAID YOKE MEANS, AND AN ADAPTER ARRANGEMENT DRIVINGLY CONNECTED TO SAID DRIVING MEANS AND INCLUDING A CLUTCH ELEMENT; AND A VALVE OPERATOR MECHANISM COMPRISING MEANS INCLUDING A CLUTCH MEMBER COACTING WITH SAID CLUTCH ELEMENT, SAID CLUTCH ELEMENT AND MEMBER PROVIDING A CONNECTION NOTWITHSTANDING MISALIGNMENT OF SAID ADAPTER ARRANGEMENT AND SAID LAST MENTIONED MEANS, SHAFT MEANS DRIVINGLY CONNECTED TO SAID LAST-NAMED, HAND WHEEL MEANS ADAPTED TO BE DRIVINGLY CONNECTED TO SAID SHAFT MEANS, MOTOR MEANS ADAPTED TO BE DRIVINGLY CONNECTED TO SAID SHAFT MEANS, AND A CLUTCHING ARRANGEMENT ADAPTED TO INTERCONNECT ONE OF SAID LAST TWO-MENTIONED MEANS TO SAID SHAFT MEANS.

Claim 3

IN A VALVE OPERATOR MECHANISM FOR CONTROLLING A VALVE, SAID MECHANISM COMPRISING A CASING, MANUALLY OPERABLE MEANS, MOTOR MEANS CONNECTED TO A GEARING ARRANGEMENT, FIRST CLUTCHING MEANS CONNECTED TO SAID MANUALLY OPERABLE MEANS AND ADAPTED TO BE OPERATED WHEN SAID MANUALLY OPERABLE MEANS IS OPERATED, SECOND CLUTCHING MEANS CONNECTED TO SAID GEARING ARRANGEMENT AND ADAPTED TO BE OPERATED WHEN SAID MOTOR MEANS IN OPERATED, A RECIPROCABLE CLUTCH MEANS ADAPTED TO BE IN CLUTCHING ENGAGEMENT WITH BUT ONE OF SAID CLUTCHING MEANS AT A TIME, MEANS FOR MANUALLY EFFECTING ENGAGEMENT OF SAID FIRST CLUTCHING MEANS AND SAID RECIPROCABLE CLUTCH MEANS, AND TRIP MEANS SUPPORTED FROM SAID CASING AUTOMATICALLY RESPONSIVE TO THE OPERATION OF SAID MOTOR MEANS TO PERMIT SAID RECIPROCABLE CLUTCH MEANS TO MOVE TOWARD TO PERMIT ENGAGEMENT WITH SAID SECOND CLUTCHING MEANS, SAID LAST NAMED MEANS INCLUDING MOVABLE TIP MEANS WHICH IS BIASED INTO FRICTIONAL ENGAGEMENT WITH A SUBSTANTIALLY SMOOTH AND CONTINUOUS PORTION OF SAID GEARING ARRANGEMENT WHEN THE MOTOR MEANS IS NOT OPERATIVE AND WHICH IS ACTUATED BY FRICTIONAL FORCES RESULTING FROM OPERATION OF SAID PORTION OF SAID GEARING ARRANGEMENT WHEN THE MOTOR MEANS IS OPERATIVE.

Claim 4

IN A VALVE OPERATOR MECHANISM FOR CONTROLLING A VALVE, SAID MECHANISM COMPRISING A CASING, MANUALLY OPERABLE MEANS, MOTOR MEANS CONNECTED TO A GEARING ARRANGEMENT, FIRST CLUTCHING MEANS CONNECTED TO SAID MANUALLY OPERABLE MEANS AND ADAPTED TO BE OPERATED WHEN SAID MANUALLY OPERABLE MEANS IS OPERATED, SECOND CLUTCHING MEANS CONNECTED TO SAID GEARING ARRANGEMENT AND ADAPTED TO BE OPERATED WHEN SAID MOTOR MEANS IN OPERATED, A RECIPROCABLE CLUTCH MEANS ADAPTED TO BE IN CLUTCHING ENGAGEMENT WITH BUT ONE OF SAID CLUTCHING MEANS AT A TIME, MEANS FOR MANUALLY EFFECTING ENGAGEMENT OF SAID FIRST CLUTCHING MEANS AND SAID RECIPROCABLE CLUTCH MEANS, AND TRIP MEANS SUPPORTED FROM SAID CASING AUTOMATICALLY RESPONSIVE TO THE OPERATION OF SAID MOTOR MEANS TO PERMIT SAID RECIPROCABLE CLUTCH MEANS TO MOVE TOWARD TO PERMIT ENGAGEMENT WITH SAID SECOND CLUTCHING MEANS, SAID LAST NAMED MEANS INCLUDING MOVABLE TIP MEANS WHICH IS BIASED INTO FRICTIONAL ENGAGEMENT WITH A SUBSTANTIALLY SMOOTH AND CONTINUOUS PORTION OF SAID GEARING ARRANGEMENT WHEN THE MOTOR MEANS IS NOT OPERATIVE AND WHICH IS ACTUATED BY FRICTIONAL FORCES RESULTING FROM OPERATION OF SAID PORTION OF SAID GEARING ARRANGEMENT WHEN THE MOTOR MEANS IS OPERATIVE.
