A humble Corniche - my first carriage clock. Something not quite right with the striking (gong). |
 | It strikes at 2 minutes before the hour and at 27 minutes past. Let's check it out. I sought the help of a Chapter 72 colleague to investigate. |
 | Many have lost the bottom plate but this one, reported to be from Shreve, Crump and Low from Boston is complete. |
 | Hmmm! elastic bands - what are they for? I had expressed a concern about chipping the glasses during case dismantling. This secures the glasses |
 | I am instructed to remove only the corner screws which hold the pillars. The movement would slop around undoing the middle ones! |
 |
Hopefully they are not too tight. There is no reason to over tighten - ok in this case. This case needs cleaning so gloves are optional but good practice |
 | Inspect each screw, keep track of which one went where. Why? |
 | Well because (as in this case) some may be replacements in retapped screw holes. Wow - how do these things happen? One is obviously longer |
 | It is now easy to turn the clock upside down and withdraw the movement vertically |
 | The clock exposed |
 | So here we have it. The clock ready for dismantling and the case safely intact |
 | Taking the hands off requires good vision and an eyegalss helps locate and withdraw the keeper pin. |
 | The hands are off, ready for removing the dial. |
 |
The pins securing the dial should have a slight overhang from the dial plate to make it easy to pull them with pliers. Again these should not be driven home hard. |
 | Now to inspect the movement from the front and side. We found the lifting pins for the striking were both very bent- how?? |
 | Straightening them will gave to wait for another day, but how does the top glass come apart? |
 | Make sure you don't try to remove the handle by twisting, remove the screws from underneath. |
 | Now it is easy to put the clock back into its case as the elastic bands keep it all in place |
 | Just slip it in easily |
 | Insert the screws in the right holes, put the cover plate on and we are back were we started with the case glasses undamaged! |
