double fusee bracket clock

[rajeshvyas]

i have one double fusee bracket clock. the rear plate is stamped - 'Corrie' London. i would like to know the mfg year of this clock. thanks 

[oldhippy]

Oh dear looks like it’s been in a fire. There is a James Corrie of London listed from 1832 to 1857 in Watchmakers & Clockmakers of the World Vol 2 by Brian Loomas. This is a late bracket clock as it doesn’t have any engraving on the back plate. So it’s about 1857. The poor thing is going to need a lot of restoring.

hi, many thanks for your valuable reply. i have recently restored it not fully but up to some extent keeping old ware and scratches all around! to my surprise the clock even so old started ticking after cleaning and re-fitting. it shows very precise workmanship by Corrie! the hammer strikes with full strength even after ages....pix attached. thanks/rajesh

Very nice job!

Nice

I'm not knocking what you have achieved but that dial would have looked better and in keeping with the clock if it had been cream and not brilliant white. It make it look modern new.

hi, again i am back with one more query. i have one single fusee large size ONLY movement with counter weight engaged on the minute wheel. now, to start with i will have to first make minute hand and then fix the dial size, so is it possible to judge the length minute hand?  

[oldhippy]

With out the dial its very hard to judge. A photo would be handy of the movement size and the case. 

[rajeshvyas]

i have attached few pix showing counter weight engaged to the minute wheel gear. i am taking a trial by loading 12" long (22guage brass) hand...  

[oldhippy]

I would say that movement is from some advertising clock going by the weight. I wouldn’t be surprised if the minute hand is about 18 to 24 inches. Its going to be a trial and error regarding the hand. Something that fits is all you need to start with.

[rajeshvyas]

good if it can hold 18-24" at present i am testing with 0.8mm thick 12" long hand. if the result is good i will further increase the length to 20-24"  

one more thing i would like to know while testing does it make any difference if i test it without pendulum? as per my knowledge pendulum regulates the speed and has nothing to do with the hand/counter weight-correct? 

[oldhippy]

You need a pendulum to determine the time, If you just let the clock trip with out a pendulum you can do harm to the pallets and the escape wheel teeth.   

[rodabod]

The greatest load will probably be somewhere around quarter-to-nine. You could just test it at the first few clicks of the fusee to check it can still run at the weakest portion of the wind (even though the fusee compensates for this to some extent). Driving the pendulum does consume energy (think about during recoil) so will need to be fitted. 

[rajeshvyas]

ok noted. i will better first make pendulum and then carry out test. thanks

hi, recently i am restoring J.W.Benson single fusee movement, the winding is given on figure '3'  is there any specific reason for this? 

[oldhippy]

What do you mean by  the winding is given on figure '3'

[Colditz]

If I was making a hand for this movement I would add a counterweight to help balance it. See pic. 

[Colditz]

As per OH I don't get what you are asking or referring to.

'Winding on figure 3'? Please elucidate.

Thank you

Does this mean that the arbor with the key-dog, used to wind the mainspring, is located near 3 o'clock on the dial (if the dial were on it)?  If something else, then I am not sure I understand either.

[oldhippy]

Colditz, that weighted hand might not be necessary as the movement is fitted with a counterweight.

Hi you might find thr following link useful as it deals with the pre tensioning of the barrel for fusee clocks amongst other things.      http://www.atmosman.com/spring.html

[rajeshvyas]

KarlvonKoln, yes you got is correct why the key used to wind the mainspring, is located near 3 o'clock? any specific reason? or just for a different design.

[oldhippy]

That is all down to the design of the movement. Most clocks have the key holes at 3 and nine 9 for a strike, if it had been a chime one of the 3 key holes would normally be at 6. 

[rajeshvyas]

oldhippy, ok- noted.  since this one is single fusee with different design- it will be good for my collection. thanks for your valuable info.
