Abstract:

From a study of nearly 300 samples of a certain type of clock mechanism it was found that the period varies some 8 above and below the most popular value. The most important reasons for this variation are 1 the differences in geometrical dimensions of the verges, 2 the differences in the center to center spacing of verge and starwheel shafts, 3 the friction of the gear train which transmits the torque from the spring to the starwheel. It was shown that shape or condition of shafts and bearing holes is relatively unimportant. Less important effects were also noted. All work described was carried out on the assumption that the mechanism is not being accelerated as a whole.
