HOOK
AND
HOOK
SHAFT
Insert
a
needle
of
the
size
required
as
far
up
in
the
needle
bar
as
it
will
go
with
the
scarf
or
spot
toward
the
pulley
end
of
the
machine.
Tighten
the
clamp

The
hook
should
be
placed
in
the
hook
shaft
so
that
the
set
screw (A,
Fig.
l)
in
the
shaft
bears
against
the
flat
(B) on
the
shank
of
the
hook
and
the
set
screw
should
be
firmly
tightened.
With
the
needle
bar
in
its
lowest
position^
the
hook
should
be
set
so
that
its
point
is
3/16
inch
from
the
center
of
the
needle
(Fig.

Gauge
No.21225-3/16
can
be
used
advantageously
in
making
this
adjustment.
In
order
to
obtain
the
above
setting
when
the
hook
is
out
of
adjustment,
it
becomes
necessary
to
re-time
the
hook
shaft.
In
re-timing
the
hook
shaft,
the
two
screws
(C,D,

CLEARANCE
From the library of: Superior Sewing Machine & Supply LLC
The
rear
feed
dog
(B)
should
be
set
slightly
lower
than
the
front
feed
so
that
only
3/A
of
the
depth
of
a
tooth
extends
above
the
throat
plate
when
the
feed
dog
is
at
its
highest
point
of
travel.
This
is
done
to
prevent
the
possi
bility
of
the
rear
feed
dog
back
feeding.
LOWER
TAPE
CUTTER
KNIFE
Lower
tape
cutter
knife
(D^
Fig.
5)
should
be
set
in
the
holder
so
that
the
knife
edge
(E)
is
located
flush
with
the
top
of
the
throat
plate.
Adjusting
screw
(F)
is
used
to
raise
the
knife
to
its
proper
height
and
maintain
this
height
when
in
operation.
UPPER
TAPE
CUTTER
KNIFE
The
upper
tape
cutter
knife
(B,
Fig.
6)
must
be
set
after
the
tape
cutter
knife
bar
(A)
has
been
correctly
located.
The
knife
should
then
be
positioned
so
that
the
highest
point
of
its
cutting
edge
passes
the
cutting
edge
of
the
lower
knife
by
1/32
inch
when
the
knife
bar
is
in
its
lowest
position.
For
efficient
operation,
the
cutting
edges
of
the
upper
and
lower
knives
must
have
a
slight
shearing
angle
so
that
there
will
be
a
cutting
action
the
whole
l^gth
of
the
blades.
This
angle
is
set
in
the
upper
knife
mechanism
at
the
factory.
-6-
From the library of: Superior Sewing Machine & Supply LLC
The
two
cutting
edges
must
exert
a
pressure
against
one
another.
The
amount
of
press\ire
should
be
such
that
it
can
be
felt
in
the
upper
tape
cutter
knife
bar
when
the
knife
bar
is
pressed
down
with
the
finger.
The
pressure
is
ob
tained
by
adjusting
the
screw
(C^
Fig.
6)
in
the
upper
tape
cutter
knife
bar.
Turning
screw
to
the
right
adds
pressure
against
lower
knife,
turning
screw
to
the
left
acts
the
reverse.
AUTOMATIC
TAPE
CUTTING
MECHANISM
The
automatic
tape
cutting
mechanism
has
four
main
adjustments.
Adjustment
No. 1
(Fig.
7)
regulates
the
stop
position
of
actuating
lever
(A).
This
stop
is
properly
set
when
there
is
a
small
eunount
of
play,
from
1/32
to
1/16
inch,
between
points
(B) and (C) when
the
mechanism
is
at
rest.
Adjustment
No.
2
is
for
the
spring
that
maintains
a
downward
tension
on
the
actuating
shoe
(D).
The
tension
on
this
spring
is
corrected
loosening
the
two
set
screws (F)
and
turning
stud
(G)
clockwise
to
increase
tension
and
counterclockwise
to
reduce
tension.
The
tension
on
this
spring
should
be
only
sufficient
to
operate
the
mechanism
promptly
as
shoe
(D)
rides
off
the
bag.
Too
great
a
tension
Fig.
7
on
this
spring
will
cause
the
shoe
to
force
the
bag
down
into
the
throat
plate
slot
(E)
causing
the
front
end
of
the
bag
to
have
uneven
tape
ends.
Tighten
screws
(F)
securely
when
the
tension
has
been
properly
culjusted.
Adjustment
No. 3
limits
the
distance
shoe
(D)
drops
into
the
throat
plate
slot
(E)
and
controls
the
position
of
cutting
as
shoe
(D)
rides
on
to
the
bag.
This
depth
of
adjustment
is
proper
when
shoe
(D),
in
its
upward
travel,
is
about
1/32
inch
below
the
top
surface
of
throat
plate
as
the
points
(B)
and
(C)
pass.
From the library of: Superior Sewing Machine & Supply LLC
Adjustment
No. 4
locates
the
position
of
shoe
(D) on
the
end
of
the
actuating
lever
extension
(H)
and
controls
the
length
of
tape
on
the
ends
of
the
bag.
The
overall
length
of
the
tape
is
a
fixed
amount
and
is
only
divided
on
each
end
of
the
bag
by
the
location
of
shoe
(D).
This
automatic
tape
cutting
mechiuiism,
although
it
appears
complicated
and
to
have
numerous
adjustments^
is
relatively
simple
in
that
all
adjustments
are
fixed
and
there
is
no
reason
to
deviate
from
instructions.
Properly
adjusted,
it
will
give
a
positive
single
clip
at
each
end
of
the
sewn
bag
and
will
not
double
chop.
Several
details
of
the
tape
cutting
mechanism
were
not
discussed
in
the
instructions
for
the
four
main
adjustments
because
they
do
not
actually
enter
into
the
adjusting
of
the
unit.
It
is,
however,
necessary
that
the
mechanic
have
some
knowledge
of
these
because
they
are
important
to
the
func
tioning
of
the
unit
in
the
event
it
should
be
necessary
to
replace
any
parts.
The
actuating
lever
dog
(A,
Fig.
8)
is
held
on
to
the
actuating
lever
(B) by a
hinge
screw
(C).
The
amount
of
hinge
of
(A)
on (b)
is
limited
by two
stop
pins
(D). The
position
of
the
dog
(A)
is
controlled
by
the
stationary
spring
and
stationary
pin
(F).
The
function
of
this
Fig.
8
spring
is
to
allow
the
point
of
(A)
to
lag
as
it
contacts
the
point
of
the
trip
dog
(G)
until
the
actuating
dog
(A)
reaches
the
limit
of
hinge
controlled
by
pins
(D).
Spring
(£)
then
accelerates
the
point
of
(A)
in
the
direction
the
lever
is
moving
to
msike
the
points
of
(A)
and
trip
dog
(G)
pass
each
other
by
a
considerable
simount
and
prevent
the
possibility
of
a
double
chop.
After
the
upper
tape
cutter
knife
(B,
Fig.
6)
has
been
temporarily
assembled
in
the
upper
tape
cutter
bar
(A),
set
the
bar
height
by
manipulating
adjusting
screw
(C,
Fig.
9)
so
that
.015
to
.020
inch
dist2ince
remains
between
the
point
of
driving
pawl
(A,
Fig.

and
the
point
of
ratchet

but
do
not
exert
a

(H)
with
screw
(a)
.
The
trip
of
this
mechanism
is
accurately
set
when
the
point
of
the
pawl
lever
extension
(A,
Fig.
11)
passes
over
the
top
of
the
point
of
dog
(B)
momentarily
before
the
point
Fig.

/
of
the
actuating
lever
trip
dog (C)
passes
the
point
of
dog
(D)
at
position
(E) when
the
actuating
lever
is
moved
either
up
or
down
causing
the
points
at
(E)
to
pass.
This
adjust
ment
is
made by
loosening
clamp
screw
(G)
and
moving
the
dog
(B) up
or
down
whichever
is
required.
NOTE;
On
machines
having
the
dogs (B and D)
in
one
integral
unit
without
any
clamp screw (G),
this
adjustment
is
made by
loosening
the
screw (F) and moving
the
pawl
lever
extension
(A) up
or
down
as
required.
Fig.

From the library of: Superior Sewing Machine & Supply LLC
The
height
of
dog
(F,
Fig.
12)
is
properly
set
hy
ad
justing
screw
(C)
against
stop
pin
(D)
until
the
point
of
the
dog (F)
is
flush
with
the
top
of
the
lever
extension
(G).
This
adjustment
and
the
one
in
the
preceding
paragraph
may
seem
to
conflict.
However,
by
working
these
two
adjustments
together
the
desired
settings
will
be
obtained.
Spring
(a.
Fig.
12)
should
be
positioned
in
the
proper
notch
of
bracket
(B)
to
return
screw (C)
against
stop
pin
(D)
during
the
clipping
cycle
when
the
dog (£)
is
free
to
move.
Another
feature
not
mentioned
in
the
adjusting
instruc
tions
is
the
action
of
springs
(A and B,
Fig.
13).
Spring
(a)
engages
the
driving
pawl
(C)
into
ratchet
lever
(D) when
dog
(E)
is
tripped
by
the
movement
of
the
actuating
lever.
It
is
important
that
this
spring
be
strong
enough
to
overcome
the
tension
of
spring
(F)
that
holds
dog
(E)
in
position.
EXAMPLE:
If
dog
(e)
is
tripped
while
the
ratchet
lever
(D)
is
in
its
forward
position
as
indicated
by
dotted
line,
pawl (C)
will
by
action
of
spring
(A)
drop
to
rest
on
top
of
ratchet
lever
(D). Pawl (C)
will
not
drop
into
operating
position
until
(D)
has
returned
to
the
back
of
its
stroke.
It
is
then
necessary
for
spring
(A)
to
drop
pawl (C)
into
ratchet
lever
(D)
firmly
and
completely.
In
making
this
Fig.
13
motion,
the
pawl
lever
extension
(G)
forces
dog (E) downward
thereby
overcoming
the
action
of
spring
(F)
which
holds
dog
(E) up
into
position.
Spring
(B)
is
a
strong
spring
and
used
only
to
cushion
the
disengagement
of
pawl
(C)
from
ratchet
lever
(D) when
the
clipping
cycle
is
completed.

from
the
clip,
pawl
lever
extension
(G)
contacts
dog

INTERMITTENT
THREAD
NIPPER
The
thread
nipper
is
set
correctly
when a maximum
amount
of
tension
can
be
applied
to
the
spring
without
breaking
the
thread
and
yet
have
sufficient
opening
between
the
tension
discs
to
allow
free
passage
of
thread
as
the
tension
is
re
leased.
After
the
nipper
mechanism
has
been
adjusted^
the
tension
should
be
relieved
and
Just
enough
tension
applied
to
eliminate
occa
sional
large
loops
in
the
stitching,
and
to
prevent
the
hook
from
catch
ing
the
cast
off
loops
causing
broken
stitches
to
occur
in
the
sewing.
The
nipper
mechanism
is
ad-
Justed
by
raising
or
lowering
the
thread
nipper
sleeve
(A,
Fig.
17)
in
the
sleeve
holder
(B).
The
opening
between
the
discs,
can
be
increased
by
loosening
the
set
screw
(C)
and
tapping
the
top
of
the
tension
post
forcing
the
nipper
mechanism
deeper
into
the
sleeve
holder.
Inserting
a
screw
driver
between
the
tension
eyelet
and
the
sleeve
holder
and
forcing
the
nipper
mechanism
up
decreases
the
amount
of
opening
between
the
discs.
The
nipper
mechanism
is
set
correctly
for
a
12-4
twine
when
there
is
a
3/64
inch
space
between
the
discs
at
their
open
position.
The
sleeve
should
then
extend
3/64
inch
out
of
the
sleeve
holder.

noting
the
position
of
the
tension
eyelets.
The
needle
thread
tension
(the
one
nearest
the
cone
of
thread)
should
be
set
so
that
Just
enough
tension
is
applied
to
the
thread
to
pull
up
a
neat
stitch.

TAPE
GUIDES
The
lower
tape
guide
must
be
set
so
that
the
delivery
end
fits
up
against
tape
opening
in
the
throat
plate.
The
tape
should
then
slide
from
the
guide
into
the
throat
plate
in
one
continuous
motion
until
it
contacts
the
presser
foot.
The
setting
of
the
upper
tape
guide
is
a
matter
of
placing
its
brackets
in
their
proper
places.
Refer
to
the
threading
diagram
(Fig.
18)
for
these
adjustments.
STITCH
LENGTH
To
set
the
length
of
stitch,
loosen
the
hexagonal
head
screw
(A,

that
holds
the
feed
drive
eccentric
connecting
rod
to
the
feed
rocker.

for
this
purpose.
Moving
the
sleeve
screw
nut
(B)
in
the
feed
rocker
slot
(C)
toward
the
cloth
plate
shortens
the
stitch,
the
reverse
lengthens
the

OILING
Before
starting
the
machine,
make
sure
that
all
oiling
points
as
indicated
on
(Fig.
20)
are
lubricated
with
a
straight
mineral
oil
similar
to
an
S.A.E.
10
W.
The
oiling
points
are
arranged
in
numerical
sequence
on
the
chart
for
the
operator's
convenience.
When
machine
is
operated
all
day
long
and
in
hard
ser
vice,
oil
twice
daily,
once
at
the
morning
start
and
again
at
the
noon
start.
If
there
is
a
large
quantity
of
dust
in
the
air,
more
frequent
oilinv-
will
be
beneficial.

FEED
TIMING
The
feed
dog
and
needle
bar
motions
are
synchronized
so
that
when
the
handwheel
is
turned
in
the
operating
direction
and
the
needle
bar
is
moved downwardly
until
the
top
of
the
eye
of
the

is
even
with
the
top
surface
of
the
throat
plate,
the
teeth
of
the
feed
dog
are
.015
inch
above
the
throat
plate
and
the
feed
is
descending.
This
adjustment
is
made
at
the
factory.
For
convenience
in
checking,
timing
marks
will
be
found
on
the
feed
drive
shaft
collar
and
its
adjoining
bushing
(F,
G,
Fig.

If
the
machine
is
synchronized
as
described
above,
the
timing
marks
will
coincide
when
the
needle
bar
is
at
the
bottom
of
its
stroke.
CAUTION:
Do
not
change
timing
of
machine
unless
it
becomes
abso
lutely
necessary.

other
adjustment
has
not
been
taken
care
of.
