ABSTRACT:
A device for indicating the status of a refrigerant storage tank and its contents. Three indicia bearing disks are separately mounted for rotation to the indicator. Each disk is divided into a plurality of annular sectors such that partial rotations of each disk expose successive sectors to view through windows in the display panel. A first disk bears indicia to display the type of refrigerant in the tank. A second disk bears indicia to display the recycle status of the refrigerant in the tank. A third disk bears indicia to display the intended disposition of the contents of the tank. A shaft is inserted through a central portion of each of the disks. Each shaft extends into apertures on the display panel and the backing plate located on the axes of rotation of the disks. A notch is provided on the periphery of each disk at the juncture of adjacent sectors. For each disk, a resilient catch partially embedded in the back plate has a free end that extends into a notch on a disk when a sector is wholly revealed in a window, thereby providing a detent for each sector of each disk.
