When out of sight of land, a navigator can decide latitude, his place north or south on the globe, by measuring the altitude of the solar utilizing solely a sextant and a nautical almanac. To find out longitude, his place east or west, nevertheless, a navigator should evaluate the time of the domestically noticed midday with the time on his chronometer, often set to the time in Greenwich, UK. The primary chronometers rugged sufficient to be used at sea had been developed by John Harrison and others within the mid to late 18th century. By the nineteenth century, marine chronometers had been adopted on naval ships and lots of service provider vessels.
However how might a navigator simply and exactly set his ship’s chronometers? To unravel this downside, the Royal Navy’s Captain Robert Wauchope invented the time ball in 1829. It was a big ball hoisted to the highest of a pole on a constructing simply seen to ships within the harbor. The ball can be lowered at a exact time, often midday or 1PM. When the navigators on ships within the native harbor noticed the ball starting to drop they might use it to set their chronometers to the precise time.

From 1913 to 1967, a time ball on high of the lighthouse would drop down the pole to sign twelve midday to the ships within the harbor. In 1976, the Titanic Memorial Lighthouse was moved to the nook of Pearl and Fulton Streets, close to the doorway to the South Avenue Seaport, in downtown Manhattan.
With the appearance of radio time alerts within the Twenties, the time balls grew to become out of date. However, the time balls on the Greenwich Observatory and the US Naval Observatory proceed to drop on daily basis to provide each locals and ships on the rivers a method of setting their watches. And, when the ball drops at midnight yearly at Instances Sq., whether or not watched by many or just a few, the bejeweled ball pays homage to Robert Wauchope’s invention, the time ball.
