ABSTRACT:
A self-contained unitary attachment engageable atop the supply tank of a beverage dispensing machine in place of the standard cover therefore. The attachment includes a liquid concentrate reservoir that depends into the beverage in the tank and up into a housing portion of the attachment. The housing portion of the attachment accommodates a proportional mixing device with inlets connected with the reservoir and a pressure water supply and an outlet communicating with the tank, a valve to start and stop the flow of water, a pressure regulator related to the water supply, liquid level sensors responsive to high and low liquid levels in the tank, a signalling device to signal when the reservoir is substantially empty of concentrate and a control circuit connected with the valve and liquid level sensors whereby the valve is opened and closed to maintain the liquid level in the tank between high and low levels. The attachment can be engaged with and removed from a related dispensing machine without modification or alteration of the machine. The attachment only has a single water supply line and a single electric supply cord extending from it to releasably connect with a pressurized water supply and a power supply. The housing portion has a normally closed opening above the reservoir to effect intermittent filling of the reservoir with concentrate.
