A STUDY OF THE EFFECT OF GEOMETRICAL FACTORS UPON THE BEHAVIOUR OF AN UNTUNED CLOCK MECHANISM

Abstract

The dependence on time delay of the following geometrical factors was determined empirically: (1) the angle at the verge corner, (2) the center to center distance, verge to wheel, (3) the radius of the tooth circle of the wheel, (4) the position of the corner points of the verge with respect to the axis of rotation of the verge. It was found that except in case (1), the empirical relationship T = B(tau to the minus 0.5 power)I sub v to the .612 power(I sub w to the minus .112 power) must be rewritten (the powers of I sub v and I sub w) to predict times T. The given relationship is correct for the geometrical situation of case (1). In each of the case (2), (3), and (4) a linear relationship (approximately) is found to hold when values of T are plotted against values of the geometrical factor being varied. The work was actually carried out for a scaled up model of a particular untuned clock mechanism.
