The Time Ball, Royal Observatory, Greenwich, Fig. 7, 1844. Creator: Unknown
The Time Ball, Royal Observatory, Greenwich, Fig. 7, 1844. The hour of one o clock is announced by the descent of a large black ball, from the summit of a pole, which surmounts the northwestern turret of the Observatory; a position singularly favourablefor its exhibition to mariners on their progress down the adjacent river Thames. The apparatus...may be said to consist of a hoist for raising the ball, a trigger and discharging gear for its liberation, and a clock, regulated by observation, for giving the required moment of time. From " Illustrated London News", 1844, Vol V
