Enfield Chime Drum Re-assembly

[Simon Holt]

This is from a 1949 Enfield P-K5A-1 Westminster chiming mantel clock:



Someone before me has had the chime drum assembly apart (see the chewed screw heads).

The problem is that it is no longer in its original configuration, and it does not play the correct sequence of Westminster chimes. There is no sequence where four descending notes occur.

I need to rectify this, but if my calculations are correct there are 24 possible configurations. Is there some cold clear logic that can be applied to get it right first time? Or does someone have drawings or photographs that might help?

These are often numbered.
Anyhow, if you line up so that the first bar of the 4/4 chime works, then that should repeat as the end of the third bar sequence.

Yes if you take the three screws out take off then the plate take the barrel out and have a look on the side of the first wheel nearest to you there should be a number 1 followed buy 2,3,4 line them up ready to strike no need to let the mainspring down.

I can't imagine a need to take it apart. That's got to be one of the oddest things I've ever seen a clock owner do.
It would make a great problem on a final exam test though

All sorted now - thanks all.

The individual 'wheels' were indeed numbered (although on the side nearest the movement). Wheels 1 & 2 had been reversed.

Note for future readers: the 2 screwed-in rods pass through (obviously!) 2 holes in each wheel. But there are 3 holes in each wheel, which tells you how to align the wheels. Furthermore, the stamped number 2 was upside-down when compared with the stamped number 3. The number 1 was sans-serif so I couldn't tell which way up it was. And I forgot to look at the stamped number 4...

Always wanted to add this to the end of a full chime sequence:

I think shutterbug was referring to the original person who disassembled it when there was no need to...

Your suggestion to disassemble it was correct and indeed the only solution.
