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 favourable for 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'.
