a
nd
screws
that
hold
the

and
the
ot
her
small
parts
will
be
found
wrapped
in
a
package.
Be
sure
to
look
carefully
through
the
material

for
p
ack
ing
b e
for
e
destroying
it,
so
that
you
will

9.
To
protect
the
machin
e
from
rusting
while
in
transit,
all
parts
are
covered
with
vaseline,
which
must
be
carefu
lly
wiped
off
before
the
machine
is
put
in
operation
.
Take
off
aluminum
head
cover
by
loosening
thumb

To
remove
this
cover
the
take-up

or
petrol
to
remove
the
grease
from
the
hook
and

case,
so
as
to
allow
the
th

over
the
hook
freely.
Also
wipe
foot,
needle
and
other
exposed
parts.
When
shipping
machines
to
distant
countries,
it
is
necessary
to
remove
the
head
mechanism
and
pack
separately,
so
as
to
insure
delivery
in
good
order.
To
aid
reassembly,
the
castings
and
gears
are
marked
with
red
paint,
showing
the
relative
position
of
the
head
mechanism
on
the
frame
of
the
machine
and
also
the
timing
of
the
gears.

importance.

ll.
In
cleaning
the
machine
always
r
emove
the
cover
from
the
head
and
wipe
off
the
parts
with
a
clean
cloth.
Do
not
use
waste
.
By
turning
the
hand
wheel
you
will
see
the
various
moving
parts
,
bear-
ings,
gea
r
s,
etc.
and
oil
holes
. A
few
drops
of
oil
should
be
placed
on
these
small
parts
daily.
On a
new
m
achine
it
is
necessar
y
to
place
a
drop
of
oil
in
back
of
the
bobbin
case
race-way
every
two
or
three
hours
.
The
hook
shaft
should
be
oiled
through
the
hole
in
the
casting
to
the
right
of
the
hook.
A
drop
of
oil
well
placed
will
do
more
good
than
ten
drops
that
do
not
reach
the
parts
requ
irin
g
it.
13.
Besides
tho
r
oughly
oili
n g
the
head
mechanism
it
is
also
necessary
to
lubricate
the
plunger
and
feed
mechanism.
The
feed
mechanism
will
be
found
in
the
bed
of
the
machine
imm
ediately
be\ow
the
presser
foot
.
This
mechanism
may
be
uncovered
by
removing
the
work
plate,
or
by
tur
nin
g the
machine
back
on
the
h
in

14.
On
all
types
of
machines
t
here
are
movable
parts
that
require
oiling
near
the
base,
immediately
below
the
hand
wheel.
By
turning
back
the
machine,
several
movable
parts
will
be
found
in
the
base,
all
of
which
require
daily
lub
r
ication
.

It
is
also
necessary
to

ADJUSTING

is
adjusted
by
turning
thumb

Figure

to
the
right
or
to

This
tension
sho
uld
be
set
sufficiently
tight
to
make
a
firm
stitch
.
Do
not,
however,
make
this
adjustment
too
tight,
because
by
so
doing
the
thread
will
draw
the
goods
and
leave
an
impres-
sion
or
dimple
·
on
the
face
of
the
goods
.
Also
thread
breakage
ma

result
if

is
set
either
too
loose
or
too
ti
ght

By
turning
this
screw

to
the
right,
th
e
tension
is
set
tighter
as
it
presses
the
bobbin
case
spring
more
firmly
against
the
thread
.
This
tension
should
be
set
r
ather
loose
so
as
to
permit
the
thread
to
draw
off
the
bobbin
freely
with
very
little
resist
a n

.
Experience
on

FigureD
ADJU
STING
WIDTH
OF
B
IGHT
36
.
The
width
of
bight
taken
by
the
needle
depends
on
several
things
,
the
"angle"
of
the
machine
being
the
most
important.
Thus
a
45°
machine
will
produce
a
wider
bight
than
a
15
° m
achi
ne,
othe
r
conditions
being
equal.
The
width
of
the
bight
is
also
dependent
on
the
depth
to
which
the
needle
penetrates
the
goods
as
well
as
the
shape
of
the
t
op
of
the
p
lu
nger
.
For
any
'g
iven
set
of
these
condi
-
tions
,
the
width
of
bight
m
ay
be
adjusted
by
moving
the
edge
guide,
Figure
E,
to
the
right
or
to
the
left
by
l
oo
sening
the
set
screw
which
holds
this
part
in
position.
By
moving
the
guide
to
the
left,
a
wider
bight
will
result,
to
the
right
will
produce
a
narrower
bight.

AUTOMATIC
TENSION
RELEASE
See
Plate

Page

87.
A
specia
l
mechanism
used
on
Lewis
Model
24-12
Machine
.
88
.
The
purpose
of
the
automatic
intermittent
tension
rele
ase
is
to
pre
-
vent
dimples
or
indentations
fr
om
showing
on
the
outside
or
face
side
of
the
material
when
felling
or
b.lind
stitch
-
ing
two
pieces
of
cloth
to
-
gether.
This
mechanism
is
especially
desirab
le
when
felling
thin
light-
weight
goods
.
89.
To
avoid
indenta-
tions
or
dimples
the
stitch
that
is
taken
in
the
canvas
FigureR
port
i
on
is
made
with
a
normal
tension
and
the
stitch
that
is
taken
in
the
facing
is
made
with
a
very
loose
tension
in
order
to
allow
sufficient
thread
between
the
two
l
ayer
s
of
material.
In
other
words,
the
facing
and
the
ca
nv
as
are
not
drawn
tightly
together
through
the
operation
of
the
automatic
tension
release
.
90
.
The
purpose
in
setting
the
stitch
in
the
canvas
with
a
normal
tension
is
to
securely
fasten
the
bobbin
thread
and
to
prevent
the
stitches
from
loosening.
While
the
stitch
is
ta
ken
in
the
facing
the
thread
is
held
under
normal
te
nsi
on
until
the
hook
has
discharged
the
loop
when
the
tension
automatically
is
released,
giving
the
thread
which
holds
the
two
layers
together
a
very
loose
tension
.
91.
CAUTION:
Do
Not
under
any
circumstances
,
loosen
set
screws
in
gear
1024,
FigureR,
above
indicated
by
arrow
in

:\
tion
.
We
especially
caution
you
on
this,
as
to
loosen

m«:ans
throwing
the
automatic
tension
release
out
of
time,
which
mechanism
is
properly
timed
when
the
machine
is
assembled
in
our
factory.
92.
In
case
it
does
become
necessary
to
time
the
automatic
:
ension
release,
this
timing
is
done
by
loosening.the
screws
in
gear
I
024.
Adjustment
is
then
made
until
the
results
outlined
in
Paragraph
90
are
obtained
.
An
approximate
method
of
making
this
adjustment
is
to
note
that
when
the
take-up
is
at
its
highest
point
,
the
single
lobe
of
the
cam
on
the
e
nd
of
shaft

should
be

After
making
this
adjustment,
it
will
generally
be
necessary
to
retime
the
hook.
93
.
The
timing
of
the
hook,
which
is
actuated
by
the
shaft
on
which
gear
1024
is
mounted,
is
provided
by
the
lower

THRE
AD
BREAKAGE;
HO
W
TO
OVERCOME
94
.
After
considerable
service
the
needle
will
be
inclined
to
cut
a
sharp
edge
in
the
gr
oove
of
the
needle
guide
,
causing
thread
breakage.
When
this
occurs,
we
recommend
r
eplacing
needle
guide
,
Fi
gure
S
which
can
be
done
at
a
very
small
cost.
However,
if
new
needle
guide
is
not
conveniently
procurable,
smooth
the
groove
with
emery
cloth
to
eliminate
sharpness.
FigureS
95.
When
thread
breakage
occurs,
check
up
on
the
parts
through
or
over
which
the
thread
passes
,
to
see
if
they
have
become
sharp.
We
refer
to
the
following
parts:
needle
guide,
n
eedle
clamp
and
thread
guide,
thread
take-up,
bobbin
case
retainer
1057
and
the
needle
.
96.
Thread
breakage
may
be
caused
by
the
bobbin
being
too
tight
in
the
bobbin
case
.
While
this
is
not
a
frequent
condition,
at
the
same
time
as
the
bobbin
becomes
old,
it
has
a
tendency
to
warp
and
bind
in
the
bobbin
case
.
Old
bobbins
should
be
discarded
.
97
.
Thread
breakage
may
be
caused
if
the
hook,
Figure
J,
page
14,
is
improperly
timed,
causing
the
point
of
the
hook
to
fail
to
pick
up
the
loop
from
the
needle
at
the
proper
time
.
See
Paragraphs
46,
47,
48
Page
IS
for
timing
the
hook.
Before
timing
hook
,
see
that
needle
is
correctly
tinled
to
plunger.
See
Paragraphs
53, 54,
and
55
Page
17
.
98
.
If
the
bobbin
is
wound
too
full,
or
if
the
thread
has
become
tangled
in
the
bobbin,
thread
breakage
will
resu
lt .
99
.
On
a
new
machine
just
put
in
operation,
thread
breakage
may
be
d
ue
to
accumulation
of
oil
in
the
hook
which
must
be
removed
as
pe
r
instructions
in
Paragraph
9.
100
.
Thread
breakage
may
a
ls
o
result
if
the
tension
of
the
needle
threa
·d
is
either
too
loose
or
too
tight.

If
the
hook
picks
up
the
needle
thread
on
the
hook's
second
revolution,
that
is
to
say,
if
the
hook
again
picks
up
the
needle
thread
after
just
dis
c
harging
it,
or
if
the
hook
completely
fails
to
discharge
the
needle
thread,
thread
breakage
will
result.
These
"second
revolu
-
tion"
breaks
may
be
due
to
several
things,
among
which
are:
the
hook
is
too
fast
,
insu!Iicient
tension
on
the
needle
thread,
insufficient
tension
on
the
thread
cont
r o
ller
spring,
or
a
combination
of
these
.
SK1PPING
STITCHES
!OZ.
If
the
goods
are
not
being
properly
clamped
under
the
f
oot
,
they
will
ride
with
the
needle
as
it
penetrates
,
preventing
the
formation
of
a
good
loop
for
the
hook
to
pick
up,
and
skipping
stitches
may
result.
See
Paragraph
37
Page
13.
103
.
Bent
or
blunt
needles
are
frequently
the
cause
of
skipped
stitches
.
Alw
ays
use
a
sharp
needle
and
see
that
it
bea.rs
on
the
needle
guide
while
entering
the
goods
.
Of
course,
when
the
needle
is
co
m -
pletely
in
the
goods,
there
should
be
clearance
b
etween
the
needle
a
nd
the
needle
guide
.
104
.
Occasionally
the
plunger
may
be
the
cause
of
skipped
stitches
due
to
its
being
set
too
low
.
Adjust
the
plunger
higher.
