描述 The oldest known illustration of an endless power-transmitting chain drive. This was illustrated in 1092, during the Song Dynasty, by the Chinese engineer Su Song in his book Xinyi Xiangfayao. It was called the "celestial ladder", and was used for coupling the main driving shaft of his clock tower to the armillary sphere gear box (which was mounted at the top of the tower in Kaifeng).
