HOOK
(SEWING)
ADJUSTMENTS
To
See
if
the
Hooks
are
in
Correct
Time.
Remove
the
slides
and
throat
plate and
turn
the balance wheel toward you until
the
needle
bar
has
passed
its
lowest
position
and
risen
so
that
the
lower
mark
on
it
is
even
with
the
underside
of
the
needle
bar
bushing.
If
in
correct
time,
the
point
of
each
hook
will
be
at
the
center of each needle and inch above the eye; if not, loosen the
screws
in
the
bevel
gear
on
the
shaft
under
the
hook
and
turn
the
gear
forward
or
backward
slightly
until
the
hook
is in
time
as
instructed
above,
then
retighten
the
screws.
Be sure
that
the needle guard on the hook washer (see Fig.
11)
does
not
deflect
the
needle.
If
the
hook
is
too
far
from
or
too near the needle, loosen hook saddle screws (bb, see Fig. 2)
just
enough to permit the saddle to be driven with light blows
to
the
position
desired,
then
retighten
the
screws.
