ABSTRACT:
A cover for a cup dispenser includes an indicating device which provides a warning when the dispenser is nearly empty. A weight at the end of a spring controlled wire reel mounted in the cover is placed in the uppermost cup and moves down as cups are dispensed. At a predetermined distance of travel of the wire and weight, a microswitch is actuated which connects a battery to turn on a light bulb or other warning or indicator device on the cover. When a new supply of cups is inserted, the weight is lifted and the spring rewinds the wire and opens the switch connecting the light and battery.
