Day and night depicting clock device

摘要

A day and night depicting clock device for demonstrating daytime and nighttime on a clock. The device includes a clock having a clock face wall and an hour drive shaft rotating once every twelve hours. A first disk is mounted on the hour drive shaft for rotation with the hour drive shaft, has a radially extending first slot, is formed of a resiliently flexible material to permit flexing of a portion of the first disk, and has a relatively light color to identify a daytime period. A second disk is positioned behind the first disk, is fixed against rotation with respect to the clock face wall, has a radially-extending second slot, is formed from a resiliently flexible material to permit flexing of a portion of the second disk, and has a relatively dark color to identify a night-time period. The first disk is movable through the second slot of the second disk. A shifting assembly shifts a portion of one of the disks with respect to another of the disks to cause the first disk to move through the second slot of the second disk to shift the first disk either from a position behind the second disk to a position in front of the second disk or from a position in front of the second disk to a position in behind the second disk. An actuating assembly periodically actuates the shifting assembly.
