It
is
desirable
to
maintain
the

the
high limit to insure
that
the

contact

b.
Insufficient interposer restoring

OPERATIONAL
INTERPOSER
LINKS
The illustration below shows
the
operational
inter-
poser
clevis
and
armature
link.
Each time one of
the
operational magnets is
energized,
the
armature pulls
on this
link,
which in turn pulls
the
interposer from
its rest position and
activates
it.
Each one of these
links must be adjusted for proper unlatching
clear-
ance.
A problem has been encountered where
the
lock
nut,
when tightened against
the
clevis,
tends
to
loosen very rapidly due to a burr on the bottom
of
the
clevis.
The illustration shows this burr and how the
loc~
nut
contacts
it,
giving
it
a very small locking
surface.
