Abstract
Abstract A drink dispenser assembly used for filling receptacles when placed into a position to receive liquid dispensed from a nozzle comprises a valve which is controlled by a solenoid connected to an electric circuit, a switch operated at the will of the operator to actuate the electric circuit and the solenoid to open the valve and initiate a filling cycle, an assembly operative to suspend the receptacle below the nozzle, and an arm positioned proximate the receptacle when the receptacle is placed into a position to receive liquid, the arm operative to sense the filled condition of the receptacle and deactuate the electric circuit and the solenoid to close the valve and terminate the filling cycle.
