Water softening system

Claim 1

IN A WATER SOFTENER SYSTEM, THE COMBINATION WITH A CONTAINER HAVING A BED OF SOFTENING MEDIUM, AN INLET CONNECTION TO SAID CONTAINER AND BED ADAPTED TO LEAD FROM A SOURCE OF WATER SUPPLY, AN OUTLET CONNECTION FROM SAID CONTAINER AND BED DISPOSED IN SPACE RELATION TO SAID INLET CONNECTION ADAPTED TO LEAD TO LOCATIONS OF USE FOR WATER, AND A FITTING IN ONE OF SAID CONNECTIONS INCLUDING A PORT FOR AFFORDING COMMUNICATION BETWEEN HOLLOW INLET AND OUTLET PORTIONS OF SAID FITTING, OF A VALVE CASING COMMUNICATED WITH BY SAID INLET CONNECTION BY WAY OF SAID HOLLOW INLET AND OUTLET PORTIONS OF SAID FITTING, SAID CONTAINER AND SAID OUTLET CONNECTION, A FIRST PIPE CONNECTION ADAPTED TO LEAD FROM SAID VALVE CASING TO SAID LOCATIONS OF USE FOR WATER, A SECOND PIPE CONNECTION ADAPTED TO LEAD FROM SAID VALVE CASING TO DRAIN, MEANS ADAPTED TO BE ACTUATED SELECTIVELY TO SHUT OFF COMMUNICATION BETWEEN SAID CONTAINER WITH SOFTENING MEDIUM AND SAID FIRST PIPE CONNECTION AND ESTABLISH COMMUNICATION BY WAY OF SA2D OUTLET CONNECTION AND VALVE CASING BETWEEN SAID CONTAINER WITH SOFTENING MEDIUM AND SAID SECOND PIPE CONNECTION AND TO ESTABLISH COMMUNICATION BY WAY OF SAID OUTLET CONNECTION AND VALVE CASING BETWEEN SAID CONTAINER WITH SOFTENING MEDIUM AND SAID FIRST PIPE CONNECTION AND SHUT OFF COMMUNICATION BETWEEN SAID CONTAINER WITH SOFTENING MEDIUM AND SAID SECOND PIPE CONNECTION, MECHANISM FOR CONTROLLING SAID MENTIONED MEANS, A VALVE IN SAID FITTING FOR CONTROLLING SAID PORT AND INCLUDING A REDUCED FLOW OPENING, RESILIENT MEANS FOR RETAINING SAID VALVE IN THE OPEN CONDITION OF SAID PORT AGAINST THE POSSIBILITY OF SAID VALVE BECOMING CLOSED IN RESPONSE TO FLOW OF WATER THROUGH SAID FITTING, AND MANUALLY OPERABLE MEANS SELECTIVELY ACTUABLE TO A POSITION ADAPTED TO CAUSE SAID VALVE TO BE SITUATED IN THE CLOSED POSITION OF SAID PORT OR TO A POSITION RELEASING SAID VALVE TO RENDER IT CAPABLE OF BEING SITUATED IN THE OPEN CONDITION OF SAID PORT, DIFFERENTIAL IN PRESSURE AT THE INLET AND OUTLET SIDES OF SAID FITTING BEING ADAPTED TO RETAIN SAID VALVE IN THE CLOSED CONDITION OF THE PORT AGAINST FORCE OF SAID RESILIENT MEANS WHEN SAID MANUALLY OPERABLE MEANS IS ACTUATED TO SAID POSITION RELEASING SAID VALVE TO RENDER IT CAPABLE OF BEING SITUATED IN THE OPEN CONDITION OF SAID PORT WHILE SAID SECOND PIPE CONNECTION IS OPEN AND THERE IS DIFFERENTIAL IN PRESSURE BETWEEN THE SOURCE AND OUTLET SIDES OF SAID FITTING, AND SAID RESILIENT MEANSK BEING ADAPTED TO URGE SAID VALVE TO THE OPEN CONDITION OF THE PORT IN RESPONSE TO CLOSING OF SAID SECOND PIPE CONNECTION AND EQUALIZATION IN PRESSURE AT THE SOURCE AND OUTLET SIDES OF SAID PORT.
