The operation of these clocks is very simple, like all good inventions are, and only uses one wheel, and less than half a dozen moving parts. When the clock sends the pulse to the hours and minutes hands every 30 seconds, it can also send the same pulse to any number of connected slave clocks. ![]() The best you can hope to achieve is around 2 to 3 seconds per month if the clock is in good condition and is set-up correctly in the right environment. This particular clock was used to drive the slave clocks. When the clock sends the pulse to the hours and minutes hands every 30 seconds, it can also send the same pulse to any number of connected slave clocks. This is all helped by having a pendulum rod made from Invar, a metal that shows far less expansion due to temperature changes than does steel. Synchronome pendulum clocks were widely used in the University to operate slave dials in lecture rooms and to control bells and timers. The genuine models built by the Synchronome company are able (to quote from their booklet)"to keep time to within 2 seconds per week, and often much better" Rates of Clocks Shortt (Synchronome) and Riefler, plotted from figures given in. #Synchronome master clock serial numbers series#They are sold as Synchronomes, which indeed they are, but they were not built by the factory! rate the clock from a long series of daily. Next release the armature and rest it against the right hand buffer '2' (Fig 3). #Synchronome master clock serial numbers serial number#So that cheap Synchronome on Ebay may not be such a good buy - always check for the serial number as a starter.Īll the factory built models should have a unique serial number on the Advance / Retard plate, something that a lot of clocks on Ebay do not have. Next, keeping the armature against the same buffer still, adjust the contacts screw to give a gap of 70 thou (1.8mm) between the two contacts. ![]() ![]() A poorly made kit version will run, but the resultant finish, and certainly the accuracy, of some of these kits can be a long way below the genuine Synchronome standard. Although having said that the factory did also supply these clocks in a kit for the home engineer to assemble himself. These are generally regarded as one of the most accurate systems, and thus were normally built to a very high standard. ![]()
