It came off a US Navy ship, which I am trying to determine which one. The seller called it a Mother Clock Never heard them called that. Thanks for any help. Aug 24, 7, 28 0 Region Flag:. Simplex is known to have produced master clocks for use on floating vessels. I am aware of one with a similar face that was used on board powered by alternating current with DC battery back-up electrical power.
Its oscilator was an accurate crystal in oven. A multi-stage transistor flip-flop divider circuitry produced 50Hz AC to drive the small motor behind the dial.Latest Projects Education.Bank nifty option chain
Thread Starter Dalaran Joined Dec 3, I recently purchased an old school clock from a show but didn't realize it is suppose to be hooked up with a master clock to run properly.
When plugged in the clock works but there is no way to adjust the time on it. There is a single extra wire which I am under the impression is to go to the Master clock to adjust the time. To my understanding the Master either tells this clock to stop if it is fast or to speed up if it is slow through this wire. However, I can't seem to find any information and how this is transmitted through the single wire. Is anyone aware of what voltage needs to be applied to this wire in order to get it to speed up and stop?
Your help is appreciated. Scroll to continue with content. Jaguarjoe Joined Apr 7, With the clock unplugged, it will be accurate twice a day.
Wait for one of those moments and plug it in again. Piece of cake. This type of clock often works by receiving a low current impulse at a fixed interval - typically once every 30 seconds. By wiring the slave clocks in series, it is possible to drive any number of slaves from one master clock impulse generator.
Although they were usually electronmechanical in operation, you can recreate a 'master clock' using an electronic crystal oscillator and divider, driving an external relay or solid state current sink devices, which is designed to provide a typical mA pulse every 30 seconds. I fitted one to an old bowling club clock 'slave', a while back. If its not hiding too far I'd love to take a look at the circuit used. This is a classic analogue North American school clock which would be one of many slaves all connected to the single master.
I believe these were only time corrected once an hour or maybe even once a day I remember being in class and seeing the needle stop It doesn't need anything applied to it in order to tick along.Accoglienza studenti neo immatricolati lunedì 5 ottobre 2020
Does the one your referring to require a impulse every 30 seconds to keep it going? Again, thanks for your help. Jaguarjoe - thanks for the offer but I'd thought about that one Just not as fun, and these were somewhat notorious for not holding the most accurate time as they would need to be corrected to the master quite regularly.Horizontal news ticker css

Hi dberrington, welcome to the message board. You will need lots of luck with that master clock. I don't know of any manuals or schematics available for them.
I'm going to move your thread down to the electric clocks forum for better exposure. Good luck with your quest. Jul 12, 4 Hi I worked for Simplex for 5 years and I have great respect for there early equipment.
I maintained clock systems for about 10 years after leaving Simplex and found that the best way to maintain there later systems is to replace the master clock. That way you can get manuals parts and support. Master clocks now cost less then a couple of Simplex service calls. Nov 1, 2 18 Male Country Flag:.
