Indexing valves adaptable for use in lawn sprinkling systems and other liquid distribution systems

Claim 1

AN INDEXING VALVE AND FLUID DISTRIBUTION SYSTEM, SAID VALVE COMPRISING A HOLLOW CIRCULAR VALVE HOUSING HAVING A TOP WALL AND A BOTTOM WALL, SAID BOTTOM WALL HAVING A PLURALITY OF RADIALLY DISPOSED OUTLETS THEREIN, FLUID DISTRIBUTION PIPES RADIATING FROM SAID HOUSING AND IN OPEN COMMUNICATION WITH SAID OUTLETS, A VALVE DISK ROTATABLY MOUNTED WITHIN SAID HOUSING HAVING A SINGLE OUTLET PORT THEREIN AND A VERTICAL STEM ROTATABLY EXTENDING THROUGH SAID TOP WALL, A FLUID PRESSURE SUPPLY LINE IN OPEN COMMUNICATION THROUGH SAID BOTTOM WALL AND THE CENTER OF SAID VALVE DISK WITH THE INTERIOR OF THE VALVE HOUSING, SELECTOR SWITCH MEANS AND DISTRIBUTOR SWITCH MEANS, MOTOR MEANS OPERATIVELY CONNECTED TO SAID VALVE STEM FOR INTERMITTENTLY ROTATING SAID DISK AND SAID SELECTOR SWITCH MEANS AND IN CIRCUIT THROUGH SAID SELECTOR SWITCH MEANS AND THROUGH SAID DISTRIBUTOR SWITCH MEANS WITH A SOURCE OF ELECTRICAL CURRENT, A TIMER MOTOR IN CIRCUIT THROUGH AN ELECTRICAL TIMER WITH SAID CURRENT SOURCE, A FIRST CAMACTUATED SWITCH AND A SECOND CAM-ACTUATED SWITCH BOTH OPERABLE BY SAID TIMER MOTOR, A SOLENOID VALVE WITHIN SAID PRESSURE SUPPLY LINE FOR SUPPLYING FLUID PRESSURE TO THE INTERIOR OF SAID VALVE HOUSING AT TIMED INTERVALS, SAID SOLENOID VALVE IN CIRCUIT WITH SAID SOURCE THROUGH ONE OF SAID CAM-ACTUATED SWITCHES, A SOLENOID FOR IMPARTING PROGRESSING INTERMITTENT OPERATION TO SAID DISTRIBUTOR SWITCH MEANS AND IN CIRCUIT THROUGH THE OTHER SAID SECOND CAMACTUATED SWITCH WITH SAID SOURCE, BOTH OF SAID CAM SWITCHES OPERABLE IN UNISON BY SAID TIMER MOTOR AND SO RELATED THAT WHEN THE FIRST CAM SWITCH IS CLOSED BY ITS RESPECTIVE CAM TO CAUSE ROTATION OF SAID DISTRIBUTOR SWITCH, THE CAM OF THE SECOND CAM SWITCH WILL OPEN THE SAME TO CLOSE SAID SOLENOID VALVE FOR A PERIOD OF TIME APPROXIMATELY EQUAL TO THE TIME REQUIRED FOR SAID VALVE DISK TO BE ROTATED BY SAID MOTOR MEANS FROM ONE POSITION TO THE NEXT WHEREBY OPERATION OF SAID MOTOR MEANS WILL ACTUATE SAID SELECTOR SWITCH AND ROTATE SAID VALVE DISK TO ADVANCE SAID SINGLE OUTLET PORT THEREIN FROM REGISTRY WITH ONE OF SAID RADIALLY DISPOSED OUTLETS INTO REGISTRY WITH ANOTHER AND WHEREBY CLOSURE OF SAID SOLENOID VALVE BY THE OPENING OF SAID SECOND CAM-ACTUATED SWITCH TO RELIEVE FLUID PRESSURE WITHIN THE VALVE HOUSING TO PERMIT OF SAID VALVE DISK ROTATION WHILE CLOSURE OF SAID FIRST CAM SWITCH WILL ACTUATE SAID DISTRIBUTOR SWITCH AND SAID SELECTOR SWITCH AND SAID MOTOR MEANS.
