Multi-lock lever and coupling

Claim 1

IN A COMBINED MULTI-LOCK COUPLING AND VALVE ACTUATING MECHANISM FOR A QUARTER TURN VALVE, THE COMBINATION OF A MULTI-LOCK COUPLING ADAPTED FOR NON-ROTATABLE ATTACHMENT TO A VALVE STEM OR THE LIKE, AN APERTURED INDICATING AND LOCKING PLATE FIXEDLY ATTACHED TO THE VALVE, THE SAID PLATE BEING SLOTTED FOR LIMITING THE ROTATIVE MOVEMENT OF THE VALVE AND HAVING OTHER APERTURES FOR RECEIVING THE HASP OF A PADLOCK IN FULL OPEN AND FULL CLOSED POSITIONS OF THE VALVE, THE SAID COUPLING HAVING APERTURED MEANS FOR COOPERATION WITH PADLOCK HASP AND THE LOCK APERTURES OF SAID PLATE, THE SAID COUPLING HAVING A BROACHED APERTURE AND AN OPPOSITE END DISPOSED PORTION FOR MANUAL GRIPPING WHEN OPERATING THE VALVE AND PROJECTING MEANS THEREON COMPRISING A LOCK SCREW FOR COOPERATING WITH THE SLOTTED PORTION OF SAID PLATE AND SECURING SAID COUPLING AGAINST ROTATIVE MOVEMENT IN ANY POSITION DESIRED AS DETERMINED BY THE LENGTH OF THE SLOTTED PORTION OF THE SAID LOCKING PLATE, THE SAID LOCK SCREW HAVING A BROACHED LOWER END PORTION SNUGLY ENGAGING THE SAID BROACHED APERTURE OF SAID COUPLING AND HAVING AN UPPER THREADED PORTION, A THREADED LOCKING LEVER MOUNTED ON THE SAID UPER THREADED PORTION OF SAID LOCK SCREW ON SAID COUPLING AND COOPERATING WITH SAID PLATE TO SECURE SAID COUPLING AGAINST ROTATION AT ANY DESIRED POSITION BETWEEN THE FULL OPEN AND FULL CLOSED POSITIONS OF THE VALVE THE SAID LOCK SCREW HAVING AN ENLARGED ANNULAR COLLAR BETWEEN SAID LOWER BROACHED PORTION OF SAID LOCK SCREW, THE AND SAID UPPER THREADED PORTION OF SAID LOCK SCREW, THE SAID COLLAR PORTION WHEN ASSEMBLED BEING LOCATED BETWEEN THE UPPERMOST SURFACE OF THE COUPLING AND THE UNDERSURFACE OF THE SAID PLATE AND BEING OF A HEIGHT SUFFICIENT TO ALLOW FOR SLIDING CONTACT BETWEEN SAID SURFACE OF THE COUPLING AND THE PLATE WHILE SUPPORTING THE ADJOINING PORTION OF SAID PLATE AGAINST DEFORMATION WHEN SAID LOCKING LEVER IS TIGHTENED.
