![]() Normally settings are adjusted using the bright and dimmable touch screen of the TCS-1, which is also clearly readable, even in direct sunlight. The entire clock system can be controlled from a central location. It therefore enables, for example, quick and automatic time zone conversion or the timesaving changeover from summertime to wintertime. The TCS-1 (Time Control System) is the control center of automated clock systems and supplies the time protocol for an unlimited number of additional clocks and all integrated automization systems. Mühle clock systems are not only suitable for ships, but also for airports and business premises. Thus it combines up-to-date technologies that make life on board that little bit easier. The Mühle TCS-1 is exactly tailored to meet these requirements, as it can not only be easily integrated into the existing on-board Ethernet, but can also be configured via WLAN. Professional navigation has particular requirements when it comes to automated clock systems. Our ship’s bell clocks retain the atmosphere of life on board and succeed in striking the right note on land too. Technology made it possible to perfectly reproduce the rhythm of rings and the sound of the bell whilst also indicating the exact time. The ship’s bell clock took over the function of the hourglass and bell. ![]() For example at 12 o’clock, there were 8 bells: ding-ding, ding-ding, ding-ding, ding-ding, or at 9.30: ding-ding, ding. Then there was a short pause before the next rings sounded. The bell clapper was operated in a specific rhythm: The full hours were sounded by a double stroke (forward and backward stroke), with the second ring being slightly louder. With each further half an hour, one ring of the bell was added until 8 bells (= 4 hours of the shift) had been reached and the next changeover took place. After the second half an hour, the hourglass was turned again and the helmsman used two rings of the bell to make it known that the second half an hour of the shift had passed. One ring of the bell indicated that the first half an hour of the shift had passed. After half an hour, the sand had run through from the top half of the hourglass to the bottom. When 8 bells rang, this indicted a changeover and the on-duty helmsman turned the hourglass. The hourglass was used to divide the daily duties aboard a ship into 6 shifts lasting 4 hours each.Īs is generally still the case nowadays, changeovers took place at 4am, 8am, 12pm, 4pm, 8pm and midnight. The hourglass was suspended above the ship’s wheel on sailing vessels, close to the ship’s bell. The name of the bell clock derives from the signal given by the ship’s bell, which was originally timed using an hourglass. The ship’s bell clock was invented at the end of the 19th century.
