BARRING
(continued)
After the last needle dip in the bar, as the
needle rises above the clamp check on the
right hand stroke and the
clamp
carrier slide
has just started to
move,
the
barring
point
shall have just slipped off the end of the bar
ring plate, as
shown
in Fig. 64.
To adjust, loosen hex-head screw beneath
barring
plate
and
move
plate
flush
against back
of
barring
point. Securely retighten hex-head
screw. Set the other barring plate in same
manner, at the last stitch in second barring
series.
Recheck
settings.
BARRING
TRIP LEVER should retain barring
slide in position
shown
in Fig. 65 until needle,
on
its
upward
stroke, has cleared clamp check.
To
adjust, ratchet the machine until barring
plate is
under
barring
point
as
shown
in
Fig.
62. Loosen the two screws, shown in Fig. 65,
that
hold
trip lever plate on either side of trip
lever
and
adjust trip lever to fall
into
notch
in
barring
slide, as
shown.
Retighten screws.
Check for correct latching action
when
barring
point rides
upon
the other barring plate.
BARRING TRIPPING POINT should
cause
trip lever to release
barring
slide
when
trip
lever strikes the tripping point, as
shown
in
Fig. 66.
To adjust, loosen large screw
shown
in
Fig.
66
and
move
point
as required.
Hold
point
in this position
firmly
while
retightening large
screw.
Do
not cause tripping point to depress
trip lever any
more
than is necessary to re
lease the barring slide, to ovoid breakage or
excessive
wear
of
lever.
Recheck for excessive play of barring slide
and
adjust the stop screw
when
necessary, as
instructed on page 24.
