REGULATION
LENGTH
OF
STITCH,
ON
MACHINE 331 K 1 :
The
length
of
stitch
is
regulated
by
moving the
pointer
in
the stitch indicator
plate
on the front
of
the
machine
as
instructed
in
Fig.
23.
When pointer
is
set
at
O
there can
be
no feeding
motion.
Maximum length
of
stitch
is
51/a stitches
per
inch.
Move pointer to desired length
of
stitch
and
firmly
tighten thumb screw.
LENGTH
OF
STITCH,
ON MACHINE 331K4: ,
Depress the feed-reversing lever slightly
and
turn
thumb screw over to the left to lengthen the stitch
or
over
to the right to shorten the stitch,
as
instructed
in
Fig.
24.
Thumb
screw
is
marked with numerals from
"O"
to
"5".
When thumb screw
is
set
at
"O"
feed
reversing lever
is
fixed
at
central position
and
there
can
be
no forward
or
reverse feeding.
When thumb screw
is
set
at
"5",
machine
will
feed
at
maximum stitch length.
REVERSE
FEED,
ON
MACHINE 331K4:
(See instructions
in
Fig. 25)
Simply depress the feed-reversing lever
as
far
as
it
will
go.
Feeding
in
reverse continues only
as
long
as
lever
is
held
in
depressed
position.
Forward feeding
is
resumed upon
release
of
lever.
Direction
of
feed
can
be
reversed
at
any
point
in
a
seam while machine
is
in
operation, without disturbing
the work. Back tacking
is
therefore readily accom-
plished
and
ends
of
seams
are
easily fastened.
The
range
of
movement
of
feed
reversing lever
is
limited by the setting
of
thumb screw
as
instructed
above
under stitch length regulation.
When lever
is
released
it
will
rise to highest point
permitted
by
setting
of
thumb screw
and
machine
will
stitch forward
at
the
set
stitch length.
When lever
is
depressed
as
far
as
permitted
by
the
thumb screw setting, machine
will
feed
in
reverse
at
the
set
stitch length.
