What is this?

[Marvo]

Can anyone identify this please? I think it's some sort of timer that's driven by an external pulse. Not sure what it might have been used for though...

 

[snowhead]

It's part of a centrallised clock system, it produces a 1 minute and probably a 1hr pulse, black dial minutes, white dial hours.

I've installed master clock systems, that isn't a master clock it doesn't have a pendulum to keep time, it looks like a repeater for a zone.

Thanks Snowhead. Any idea what it might have been used for and maybe how old it is? I was guessing maybe 70's or 80's. It obviously wasn't used for telling the time as such so I was also guessing it might have been for a factory clocking in/clocking out alarm type arrangement or maybe a school alarm system for the lessons bell?

A bit before that Marvo. 30's more like. They were used in many large factories to govern the clocking machines.

wouldn't be surprised to find one in your shed, tony. LOL.

 

[High Tower]

Tony has one for his alarm clock!!

Remember they had a sysytem like that on the old SS Oriana, it was a sod when a circuit stopped working as all the clocks where wired in series so you had to go around everyone off them to find out which one had had the wire pulled out by some drunken Aussie git.

I had a feeling I'd find myself in the line of fire.

OK I’m a bloody dinosaur.

Think you'll find they still use a modern version of exactly the same thing, in large company office blocks and the like. It basically gives the whole building the same time on all the clocks!! Same thing i would guess for employee clocking in/out, time card locations!!

Happy belated's mate! I'm guessing that the next one is the big 60 for you then

1930's.....they had one of these along with an old mains powered clock in my Student Halls of Residence, I used to admire it every day it was a westclox clock, then some idiot smashed it off the wall one night (was about 15feet up) with a football and it got replaced with a Battery clock of a similar size, was a big old clock about 60cm across....

Thanks Tony, my guess wasn't an educated one, I've no experience whatsoever with these old master/slave clock systems. I was guessing much later because of the PVC wiring and the general condition of the brass etc.
