    Bulle Post Your Bulle-Clocks Here

    Russell 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...

    Russell 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...

    Bulle Post Your Bulle-Clocks Here

    Hi Russell 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...

    Junghans carriage clock?

    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. Regards, Peter

    Senden Clock Factory

    Hi 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...

    Eureka My first Eureka

    Frank 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...

    Eureka My first Eureka

    Spark Quench 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...

    Eureka My first Eureka

    Hi Jerzy 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...

    The cover of "Clocks -January 1997" has a picture of the Eureka glass dome. Unfortunately there is no additional information about the clock within the magazine. Regards, Peter

    Brillie Brillie Magnetic Coil

    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...

    Bulle ANOTHER COMPLETE BULLE

    Thanks Jim Whoever painted the dial did a very good job. I thought I'd share my "on a budget method" using wet transfer and a inject printer. In the attached I have actually printed the restored image on the back of the original. This is from an Bulle XA model with a diameter of around 14 cm...

    Bulle ANOTHER COMPLETE BULLE

    Jim Another great restoration. Which method did you use to restore the dial ? It looks very good. I have experimented with using wet transfer on a standard inject printer. Its a simple and cheap method. The results are reasonable, but don't look as good as yours. Regards, Peter

    Bulle Post Your Bulle-Clocks Here

    Good point Frank. I have a couple of 1/2 second models that have something similar. And of course the Brillie type clocks also have a small magnet mounted about the coil. The reason why I highlighted the 1/4 second ATO clock is the battery will normally sit between the primary magnet and the...

    Bulle Post Your Bulle-Clocks Here

    Interesting observation about the impact of battery type on electromagnetic clock regulation. I think there are 2 possibilities here: 1) The under load voltage supplied by the C & D batteries were slightly different. I have often observed that as the battery drains, the amplitude will reduce...

    Bulle BULLE DIAL

    Jim Good that it worked. I agree you would have to be careful with any treatments hoping to preserve the finish. Lacquer would be too risky, so i agree with using micro-crystalline wax. I find it does a pretty good job in protecting brass - and its easy to apply with a soft cloth. the brass...

    Bulle BULLE DIAL

    Jim You're right that the bezel cannot be removed. The best approach is to use thin brass shims to protect the dial face and clean the bezel with fine grade wire wool There are more details shown in the Horologix Restoration # 6792 Regards, Peter

    Bulle Post Your Bulle-Clocks Here

    Thought people might like to see a less common Bulle. Quite a striking case. The clock features in the 1925 catalogue. Unfortunately when I acquired the clock it had been "updated" to a quartz movement. I have since found a suitable replacement movement (XC) - so all is as it should be...

    Bulle Clockette

    Hi Nice clock. Its difficult to be 100% certain from your photos, but it does look like the iso-spring is under some tension. I base this on the separation of the coils. if you slacken off the tension in the iso spring a tad (by moving the lower bobbin up slightly), you will slow the clock...

    Barr & Poole Poole Executive#5 Electromagnetic Clock

    Uhralt That's good progress. With 38 oscillations the clock is running very nicely. I am sure you will be able to regulate it without any problems. Peter

    Barr & Poole Poole Executive#5 Electromagnetic Clock

    Uhralt I have attached a copy of the original Poole patent which may be helpful. There is also an article by Turner which seems to show more detail. My model has a brass strip contact that attaches to the underside of the end cap. The 3 D-cell batteries are held in place solely by the springy...
