pivot. Grease at this point picks up dirt and card chips, and
may cause escapement failures. Observe the armature while
backspacing. If the armature drags with the movement of
the escapement wheel, the armature pivot spring requires
adjustment.

The escapement armature pivot spring must hold the
escapement armature against the yoke at the pivot point as
shown at 2, Figure 4-2. Avoid putting sharp bends in spring
straps while forming them. The outboard edge of the
armature is notched at a point near the hole for the
operating pin; the end is ground at a Sdegree angle. The
armature must be upright for proper operation.
