sword strikes the spacing atop post.
Under these conditions, there will be
some clearance between the sword and the stop post.
Unhook the armature spring at its adjusting screw and with the
selector armature in its operated (au.RicrNG) posit ion, move the
marking
arm
of
the No.
1
sword against the s elector armature extension. Then rotate the arnm.
ture slowly to ward the SPACING position until the armature just leaves the
markin& arm of the No.
1
sword. Check the clearance between the No.
1
sword
and the markin& stop post in the sa:ne mamer as described in the foregoing.
With each selector lever on the peak of its cam, each associated
sword should be tried for· the
·
f.oregoing requirement of some clearance, not more
than
.040",
between each sword and the stop posts.
To adjust, tighten the armature bracket mounting screws j ust enough
so that the bracket m� be moved by tapping it lightly.
By
rotating the
bracket on its pivot, the clearance between the sword and the s top posts
may
be
regulated. If this clearance is more than
.040",
move the bracket in a direc
tion to bring the armature toward the sword. If there is no clearance, move
the bracket in the opposite direction to bring the armature away fro m the
sword.
If the clearance between the sword and one stop post is close to·
zero and the clearance between the sword and the other stop post is more than
.OL.Q11,
it will be necessary to refine the ••Selector .Armature Bracket
Link
Adjustment" as follows:
Loo sen the
arma
ture bracket mounting screws and the armature bracket
link screw and move the armature bracket to the right or left so that the rear
end of the link will move in the direction corresponding to the post at which
a greater clearance is desired; i.e., if the clearance between the sword and
the right stop post is less than that between the sword and the left stop post,
move the bracket to the right.
Tighten the bracket link screw and proceed to
adjust the armature bracket according to the preceeding p aragraph.
After the bracket is set and both screws are tightened, move the
bracket eccentric against the bracket and tighten the screw. The eccentric and
bracket link
will,
therefore, determine the position o·f the bracket. The
bracket
.IJ1SiY'
be removed by siuply ra�noving the two bracket screws.
In replacing,
the bracket should be held against the eccentric atop, while the two bracket
screws are tightened.

The No. l sword arms (right

arms of the selector armature extension
.04011
to
.04211
when the front edge ot
the opposite sword
ann
is against its armature extension
arm
and the No. l
selector lever is on the high part of its cam. To adjust the clearance of the
right arm, remove the locking lever spring
and
reposition the unoperated stop
screw with the armature in its unoperated position,
(See Figure
33).
'l'o
adjust the clearance of the left arm, reposition the operated stop nut with
the armat:. ure

its operated position. If necessary, pinch the nut
to
make it
tight on its screw. Recheck the right
arm
and replace the locking lever
spring.
