I am working on a Seth Thomas #10 calendar clock with the Lyre movement. It has not run for many years. The present owner has not seen the clock run for 25 years or so. The clock has previously been bushed, the pivots were fine, but I polished them, and the movement was cleaned etc. It appears that the escapement is a source of the problem. I suspect that the pallet strip and the pin have been changed and I can't get any type of adjustment will make the clock run for more than a minute or so. The movement has a 50 tooth escape wheel, 1.325" in diameter, and the span of 9 1/2 teeth is .655". The verge wire has obviously been changed as it is soldered on to the pallet strip. The distance between the pallet faces is also .655". Perhaps the little plate that the pin is on is also changed. The plate/pin assembly is fixed to the movement by a brass screw. Maybe this pallet strip was made, but incorrectly. The pin that the verge saddle fits on has been changed, or the whole piece is a replacement. One can see that the hole is enlarged and oval and this allows adjustment up and down as well as in an arc using the screw as a pivot point. This combination of adjustments makes it troublesome to find a proper position. When I find what seems to be a good position for the verge, with the drop and lock seeming to work properly, and the beat set, the clock suddenly stops within a few seconds. The illustration in Tranh's book are very grainy and it is difficult to magnify. If anyone has some suggestions, I would appreciate them.
