Something for the Weekend Part 2


RogerH

Recommended Posts

As per an earlier post, I acquired a couple of clocks to keep me busy over the winter weekends. The first one, an Ansonia Clock (From my first post) has gone well. TBH it was working fine with no wear in the pivots etc and as my old dad would say, "if it ain't broke then don't fix it!" so a good clean up and off we go.

The second clock needs a lot more work. I believe it's a late 19th century German made wall clock - it has a mounting bracket although someone has very kindly stuck some lovely plastic feet on it! There's no labels or marks that I can see other than a standard R&A pendulum. The cabinet is falling apart and the mech is seized. The cabinet just needs a lot of stripping, gluing and probably re-varnishing. The mech I have stripped right down, cleaned, lubed and re-aligned - apart from being a bit dry there was a bent pin in a pinion gear which I've straightened out - is it ok to do that? otherwise it's in a jig running quite merrily.

Does anyone have any knowledge of these clocks and the mechanism? is there anything to look out for? and what is the best way to clamp the mainspring? I used a cable tie but I'm sure there are better methods.

That is German; many call them Vienna wall clocks which they certainly are not. 30 hour or I think in your case 8 day. I can’t see the end of the mainspring; it could have a rivet going through it so the spring would need to be put over the plate post before putting it together you can buy mainspring clamps,  or if it has an open end the spring can be put on after the works are in place between the two plates. Mass produced open end anchor escapement. The winding arbor looks nice and square.

My dad used to laugh (under his breath) when his customers would refer to these as "R & A" clocks, not realizing what the "R" and "A" stood for.  Great memory.

I know what you mean......not very appropriate by today's standards lol

A nice old clock will clean up well.  As Old Hippy said use clamps for the mainspring,cable ties can break ans these springs have a nasty bite.

is there a standard set of clamps and a good place to buy them? and there's a further development. I don't have a lot of experience with genuine antiques so I can only go by instinct and the mech on this clock doesn't feel that old. it may be just cheaply made but the quality doesn't seem to be there - all a bit thin and machine made. Are there certain signs to look out for when it comes to the real deal or a modern copy? I could be wrong and it's genuine enough but when I gave it a little wind there was an impressive twang noise and the main spring fell apart!! The spring loops over one of the main support struts in answer to Old Hippy's question and has a slot at the other end that hooks over a raised part of the shaft. As per the pictures, can this be glued back on? it's a tight fit but slips under pressure.

As far as I can see it's supposed to be one main spring but the outer ring slips off. It's tight but when under pressure from the spring it slips. I'm tempted to rough the surface a bit and glue it back on but wondered if anyone has seen this before?

As Old hippy says NO glue as it will break away when under pressure. Its unusual in that its in two parts as the wheel is usually cut as one and fitted to the arbour, primarily because of the tension of the main spring applied through the wheel, So either replace the wheel in its entirity or solder it in place as Old Hippy said which may be the better bet as the quality of the mechanism is adequate for the task  but not great. A mass produced item.  Checking for quality check the plate thickness and the pillars that support the frames, better still get a good book. Laurie Penmans, clock repairer's manual. Donald De Carle's practical clock repairing, are but two publications worthy of note and contain valuable information.

Just as an update, On the mainspring, I filed some small holes around the wheel and put a little brass bar through then soldered these - I thought it would give it a bit more grip. I also flowed the solder around it too - filed it smooth and off we went. It wasn't too pretty tbh but it works ok. and the clock is now on the wall for as long as the wife can stand it!

It does however,  have quite a loud tick. is there a standard technique of dampening so it's quieter?

    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
    • Isn't that the same guy who told Zelenskyy to escalate the war with Russia/Putin when they already had a peace deal? 2 years later and we have half a million young Ukranian boys dead. He doesn't seem very clever...
    • Thanks guys.  quick question. For automatic movement, particularly this one. can I power down the main spring by pushing this rachet down?  i've gotten pretty used to SW210 and powering down a manual movement. But so far i've only been waiting for the auto movement to run out of juice before opening the case.
