We show the gold spring separate at Fig. 144. A slight torsion or twist
is given to the gold spring to cause it to bend with a true curvature in
the act of allowing the discharging pallet to pass back after unlocking.
If the gold spring is filed and stoned to the right flexure, that is,
the thinnest point properly placed or, say, located, the gold spring
will not continue in contact with the discharging pallet any longer time
or through a greater arc than during the process of unlocking. To make
this statement better understood, let us suppose the weakest part of the
gold spring _H_ is opposite the arrow _y_, Fig. 141, it will readily be
understood the contact of the discharging stone _h_ would continue
longer than if the point of greatest (or easiest) flexure was nearer to
the pipe _C_. If the end _D^2_ of the horn of the detent is as near as
it should be to the discharging stone there need be no fear but the
escapement will be unlocked. The horn _D^2_ of the detent should be
bent until five degrees of angular motion of the balance will unlock the
escape, and the contact of discharging jewel _h_ should be made without
engaging friction.
