, consequently, when power is applied to the scape tooth
S
, the pallet is drawn into the wheel. The disengaging pallet inclines in the same direction but away from the center
A
; the reason is obvious from the former explanation. Some people imagine that the greater the incline on the locking edge of the escape teeth, the stronger the draw would be. This is not the case, but it is certainly necessary that the point of the tooth alone should touch the pallet. From this it follows that the angle on the teeth must be greater than on the pallets; examine the disengaging pallet in [Fig. 5], as it is from this pallet that the inclination of the teeth must be determined, as in the case of the engaging pallet the motion is toward the line of centers
AB
, and therefore away from the tooth, which partially explains why some people advocate 15° draw for this pallet. As illustrated in the case of the disengaging pallet, however, the motion is also towards the line of centers
AB
, and towards the tooth as well, all of which will be seen by the dotted circles
