  • Moon phase display clock
    Patent number: 4692031
    Abstract: A clock for indicating moon phase comprises a moon phase dial fixed to a hub rotatable around an axle for indicating the moon phase according to the angular position thereof relative to the axle. The moon phase dial has a set of circumferentially spaced peripheral projections manually engageable during correction of the angular position thereof. A moon phase gear is slideably disposed around the hub and is driven to continuously rotate around the axle at a rotation period related to the moon phase period. A slip mechanism is disposed between the moon phase dial and the moon phase gear and frictionally engages between the face of the moon phase gear which is opposed to the moon phase dial and the periphery of the hub.
