  • One way gear train
    Patent number: 4207777
    Abstract: A gear train comprising a drive gear, a driven gear and an idler arranged a common plane so that both drive gear teeth and idler teeth mesh with the driven gear teeth. The teeth are asymmetric and the idler and drive gears are reflections of one another about a line. Rotation can be transmitted in one sense only and in direction from drive gear to driven gear only. The arrangement may be advantageously employed in timepieces such as electric wrist watches where a stepping motor drives time indicating hands.
