The glass dome (approx dimensions)
OD: 186 mm
ID: 180 mm
The battery columns are available from Carlton Clocks. They quote the following dimensions:
Height: 165 mm
Diameter: 55 mm
Wall thickness: 0.5 mm
Wooden base diameter is approx 220 mm
The serial number is on the movement. You will find that there will be one or two digits hidden behind the brass nut securing the movement.
I have attached a link which gives a rough guide to the date. I'm not sure whether this is the...
The email address is correct. There is no "full stop" at the end......this just denotes the end of the sentence.
If you respond to my "conversation" and include your email address, then I can send you a test message.
There is a very good article written by David Read. it is entitled "The Electronic Remontoire" published by AHS in 2011. Your movement is very similar to the Reform movement - although the Reform is higher quality.
The 4.5 volts flat batteries are still readily available, so there...
You're very welcome.
Just for completeness, i have attached a photo of the other style of "Manufrance Bulle" that I own. The movement is identical.
I did spend a while trawling through images of Manufrance catalogues to see if I could match the advert style. It wasn't conclusive, but...
The "pointer" on the rating nut is to hold it in the set position.
I usually use lemon juices / salt to tackle battery acid corrosion on brass. I guess soaking in any mild acid should be ok. You would then need to periodically use a stiff brush to try and remove the residue. It will...
I have a couple of similar Manufrance Bulle clocks. One is identical to yours, the other has a slightly different design of case. The movements are the same.
The design feels like it is relatively late. The wiring is plastic-coated candy stripe. There is also no iso-spring. It has a...
You often find these clocks with alarms. The alarm can either be a normal bell or in some cases a little musical box housed in the base.
There is a 1988 article in the NAWCC Bulletin by David Stevenson entitled "One Man's Joker: Another mans Joker" which has more information.
I believe the type of movement is often referred to as a inverted Sully, or reverse Sully. If you search the Forum for "ODO" you will see a similar type of movement. With the ODO, the gearwheel is made of brass, rather than plastic.
The type of movement was pretty commonly used by companies...
You're right that the different designs of electrmagnetic clocks use different coil type and draw different current. However I can't see any obvious trends or logic.
The ATO clocks all have similar coils and resistance (low current) yet the vertically mounted contacts do not have a...
Good point Frank
The attached link gives some very useful information on spark quenching - and indeed recommends a parallel resistor as the bet solution.
Both ATO and Reform did use a resistor in some of their base case design. These clocks were made some 10-20 years after...
Certainly the case in your post would look great.
As Jim mentioned, there is quite a lot of information on this forum as well as the book by Alan Shenton. I would also highly recommend the Horologix website that has a large number of Eureka restorations with detailed photographs and...
Just resurrecting an old thread that I thought would benefit from a few more details.
I have just taken delivery of a Brillie wall clock. Before it arrived I though I needed to raid my spares in case the coil was damaged. As it turned out all was fine. However I do have a badly damaged coil...
