Clock problem

[Tilly]

Can anyone give me any advice on my clock. The timer has always taken forever for it to cause the bar to drop in fact when i first got my table it took just over 30 mins.
On inspection everything seems to be working fine and after adjusting the screw as far as i can were now down to 23 mins ish.
One point that i would add as that when first started the clockwork mechanism sounds fine but as time progresses it slows and only seems to speed up with the vibration caused by a ball dropping.
This leads me to suspect that the spring is tired and needs replacing but if so where on earth do you source a similar spring
if thats what the problem is.
Also the coin shute has gone Walkies any one got any ideas of what i could use as a substitute.

Any advice much appreciated Till

If only I could get my clock to run for 30 minutes!! :'(

Which type of clock is this?

Actually if you read this post and you or one of your team own or part own a table can you just leave a comment.

Just wonder how many tables there are out there where forum and league members have a vested interest.

Advice for Till...................

Well, you have already twigged on how to adjust the time setting using the little screw, and have brought it down to 23 minutes, so I'd leave it at that. Bear it mind that these tables have stood the test of time and their technology of 70 years ago is difficult to better in this day and age. Changing a spring might be viable if you could get a match from a hardware store, but you might get an equal result by just adding some drops of 3-in-1 Oil.

As regard the coin chute, I'm sure I read somewhere recently that someone had produced a Heath Robinson-type replacement, but can't find the relevant article. Perhaps Sav can advise, as is usually the case.

OK............What little screw??

So far I have been working on a large nut and bolt and a regulator balance

What little screw did I miss????? ::)

PS small diamond French

Sorry, large nut and bolt.
Was out drinking earlier, and trying now to watch Michael Douglas film at same time, and there's a lot of 'screwing' in it ! ;D

There are three methods of altering the time the bar takes to drop. If the clock is running to completion there is unlikely to be a major problem. Always lubricate the wheel spindles as your clock will be useless if the clock wheels enlarge the spindle holes. These clocks always run slower as the time runs out.

Re the clock in question a picture would help to judge the ticker arm balance.

Adjustments;

1) The thrust bolt on the middle of the bar end of the clock that trips the bar lever.
2) Adjusting the position of the weight on the ticker arm of the clock, further out runs longer.
3) Increasing / decreasing the weight on the ticker arm (small washers etc), heavier weight runs longer

The vital part is to do the preliminary adjustment on the ticker arm if you are trying to make the clock run longer. You cannot make the clock run longer than the ticker will run for. If you adjust the thrust bolt for more time you may run out of clock!

Thanks for the advice i will take tommos advice and leave the spring be , i had previously put 3-in-1 on the relevent parts but it made little difference. I will move the weight in on the ticker arm as sav has suggested.
The clock is french and has "Brevete S.G.O.G "stamped on it and it has a "19" stamped on one of the parts inside, which as im not mechanicaly minded i wont even attempt to name.
