ABSTRACT:
Globe clocks for indicating time at various points in the world by illumination of such points as a function of time by light systems which simulate the sun. In a first preferred embodiment, the globe clock is characterized by a transparent or translucent globe rotatably mounted on a pedestal with a clock mechanism mounted on a shaft extending through the globe and effecting rotation of the globe at a predetermined rate of speed. A gear and linking mechanism is provided in association with the clock mechanism to facilitate sweeping movement of a light in a vertical arc inside the globe to simulate changing of the seasons as the globe rotates. In a second preferred, embodiment the globe clock is characterized by a transparent or translucent globe which is rotatably mounted on a base or console containing a clock mechanism which effects rotation of the globe at a predetermined rate of speed. A gear and linkage mechanism is provided on a shaft extending through the globe to facilitate movement of a light in a sweeping vertical arc to simulate changing of the seasons as the globe rotates.
