18. Latching 'of the Intermediate GroupinA Lever
side of the notch in the intermediate pawl grouping lever
(Figure 18).
The setscrew in the eccentric collar of the pawl align-
ing lever stud must always be tight. If the grouping latch
does not bottom in the notch of the intermediate group-
ing lever, the grouping lever may be positioned too far
toward the tails of the escapement pawls. This would
cause the spring lugs of the 4 and 8 pawls to restrict the
full travel of the latch.
THE PAWL GROUPING LEVER should be adjusted to just
group the escapement pawls when the tab lever is in its
latched position (Figure 20).
To move the grouping lever it is necessary to unlock
it from the back space interlock lever in two places, the
adjustment locking screw and the locking nut on the pivot
stud (Figure 19). Tighten the two points securely when
the grouping lever is positioned correctly. Note that the
