  • Purified water dispensing apparatus and method
    Patent number: 5333660
    Abstract: An improved apparatus and method for self-service dispensing of purified water with enhanced efficiency and safety. Personal injury and property damage caused by inadvertent impact of the movable dispensing spout is prevented by use of an adjustable slip clutch connected to the spout drive motor. Additionally, intermittent delivery of small quantities of purified water i.e. "topping off", is achieved without a motorized pump through manual tapping of an accumulator tank of variable storage capacity, containing a pressurized internal bladder. When emptied, the accumulator tank activates a motorized pump to provide for refilling the tank.
