Post subject: tubular chimes
If you are familiar with the Westminster chime melody it is a lot easier to figure out which chime tube belongs where.
Starting with 1/4 past the hour (which is the easiest). The chime is four notes descending down the scale. By watching which hammer strikes when the first quarter is playing, it should tell you which chime tube should be where on the rack. Those same four notes are repeated in a different sequence for each quarter hour, except that the number of notes increases with each 1/4 hour. (e.g. 8 notes on the half hour, 12 notes on the 3/4 and finally 16 notes on the hour).
Trinity is, of course, a 6 note chime with the extra two notes being higher up the musical scale than Westminster chimes. I'm basing this on a clock with Trinity chimes that I have, The extra two notes are never used for the Westminster chime. The first 1/4 hour of the Trinity chime is 6 notes descending down the scale. Again it is the easiest part of the melody to figure out.
Generally the chime tubes are hung so that they are evenly graduated in length from left to right or right to left.
I have a mantel clock with Trinity and Westminster chimes. However, the manufacturer (HAC) has the chime rods placed slightly out of sequence, so it's useless as a model (except for the way the two melodies should sound when played).
Normally there should only be six tubes in the clock to cover both melodies.
Herschede floor clocks usually had one extra tube. It's only function was to sound the hour strike and it was considerably longer than any of the others and was hung slightly offside from the other row of chime tubes.
Just as an aside...Be thankful that your clock isn't a Charles Jacques tallcase monster clock with eleven chime tubes. It plays any of seven melodies, advancing to a new tune for each day of the week....and no, the chime tubes are not hung in sequence across the back of the clock. Apparently it can be a technician's nightmare to set up. (I still want one though).
