the c orners of the base. Place the machine on these pads, and
with the four studs through the rubber bushings.
CAUTION

the
AAachines
Machines
147-88,
147-110
and
147-111
are
each
equipped
with
an
oiling
system
Which
automatically
delivers
the
required
quantity
or
oil
to
all
principal
bearings.
See
large
diagrams
on
pages
18
and
19.
A
scoop
in
the
connecting
rod
takes
oil
from
the
reservoir
and
lubricates,
by
splash,
the
various
bearings
in-
side
the
machine
arm.
Some
of
this
oil
is
caught
by
a
cup
(with-
in
the
amm
from
which
it
is
distributed,
through
pipes
and
wicks,
to
the
principal
bearings
outside
the
machine
arm.
TO
INSURE
OPERATION
OF
THIS
OILING
SYSTEM,
IT IS
ESSENTIAL
THAT
THE

The
size
or the
needle
to
be
used
is
determined
by
the
size
of
the
thread
which
must
pass
freely
through
the
needle
eye.
Rough
or
uneven
thread,
or
thread
which
passes
with
(iifficulty
through
the
needle
eye,
will
interfere
with
the
proper
operation
of the
machine.
Orders

specify
the

also
the

HOW
to
Determine
the
Twist
Hold
the
thread
as
shown
above.
Turn
the
thread
over
toward
you
between
the
thumb
and
forefinger
or
the
right
hand;
If
left
twist,
the
strands
will wind
tighter;
if
right
twist,
the
strands
will
unwind.
To
Set
the
Needles
Insert
the
needle
as
far
as
it
will
go
up
into
the
needle
bar
of
Machine
147-88,
or,
in
the
case
of
Machine
147-110
or
Machine
147-111,
insert
the
needles
as
far
as
they
will
go
up
into
the
needle
clamp
-
in
every
case
with
the
single
continuous
groove
of
each
needle
toward
the
operator,
then
securely
tighten
the

and
tighten

To
Change
the
Sidewise
Position ot
the
Loopers
with Relation to the Needles
The
loopers
should
be
set
as
close
as
possible
to
the
needles
but
without
actually
touching
the
needles
on
the
forward
and
backward
strokes
of
the
loopers.
To
adjust,
loosen

or
loosen

(03,Fig.13)
on
Machine

and
move
the

should
be

1/8
inch
below
the
points
of
the

so
that
the
needle
eyes
and
the
eyes
of
the

will
be
in

ment
when
they
pass

Needle
thread

is

set
with
the
bottom
of
the

flush
with

To
Adjust
the
Slack
Thread
Regulator
The
slack
thread
regulator
(D4,Fig.15),
on
the
front
of
the
machine,
should
be
set
so
that
when
the
loopers
are

To
Adjust
the
Slack
Thread
Regulator
and
Auxiliary
Thread
Take-Up
needle
loops
on
their
backward
stroke,
the
thread
will
not
snap
from
the
looper
points
nor
be
drawn
through
the
tension
discs.
To
set
the
slack
thread
regulator,
it is
best
to
start
with
the
regulator
in
a
low
position
and
then
continue
raising
it
until
the
loopers
back
out
of the
needle
loops
with
a
little
tension
on
the
thread.
To
make
this
adjustment,
loosen
the
clamping
screw
(C4,F‘ig.15)
and
raise
or
lower
the
slack
thread
regulator
as
may
be
required,
then
securely
tighten
the
clamping
screw
(C4).
To
Adjust
the
Auxiliary
Thread
Take-up
The
auxiliary
thread
take-up
(E4,Fig.lF)
at
the
front
of
the
machine,
should
be
set
to
take
up
the
slack
of
the
needle
threads
after
the
loopers
have
shed
the
needle
loops
and
as
the
needle
bar
finishes
its
downward
stroke
and
the
stitch
is
set.
To
change
the
position
of
the
auxiliary
thread
take-up,
loosen
the
screw
which
holds
it
in
position
and
raise
or
lower
it,
as
re—
quired,
then
tighten
the
screw.
For
some
threads
it
will
be
necessary
to
set
the
auxiliary
thread
take-up
at
a
height
different
from
that
required
by
others,
owing
to
the
differences
in
finish,
twist,
elasticity,
etc.
23
To
Adjust
the
Automatic
Thread
Nipper
The
automatic
thread
nipper
(5,Fig.15)
at
the
front
of
the
machine,
makes
it
possible
to
set
the
stitch
tightly without
using
a
heavy
tension
on
the
needle
thread.
The
nipper
discs
should
open wide
enough
to
permit
the
thread
to
pass
freely
bemeen
the
discs, and
should
close
and
nip
the
thread
immediately
after
the
looper
has
cast
off
the
needle
loop
on
the
downward
stroke
of the
needle
bar.
To
adjust
the
nipper,
loosen
set
screw
(BB,Fig.15)
and
move
the
nipper
body
inward,
or
away from
you,
for
a
greater
opening
of
the
discs,
or
outward
for
a
smaller
opening.
When
the
desired
adjustment
is
obtained,
tighten
the
set
screw
(BS).
To
Adjust
the
Needle
Thread
Tension
Releaser
The
needle
thread
tension
releaser
must
release
the
tension
on
the

Assembly
(R5,Fig.23)
in
the

frame,
and
remove
the
shaft
(Qb’,
Fig.23).
The
under-reed
assembly
can
then
be
removed
from
the
machine.
To
Remove
the
Upper—Feed
Regulator
Assembly
Take
out
the
stud
(LS,Fig.23),
also
remove
the
two
screws
in
the
upper-reed
eccentric
connection,
and
remove
the
cap
(J5,Fig.
23).
Then
remove
the
three
screws
which
fasten
the
upper—feed
regulator
bracket
(K5,Fig.23)
to
the
base
or
the
machine,
and
remove
the
bracket
together
with
the
upper-reed connecting
rod.
To
Set
the
Feed
Dog
at
Correct
Height
When
the
reed
dog
is
at
its
highest
position,
practically
the
full
depth
or
the
teeth
should
project
through the
slots
in
the
throat
plate.
The
height
or
the
feed
dog
is
determined
by
the
29
stop
screw
(S4,F‘ig.25)
which,
with
the
reed
dog
removed,
may
be
turned
up or
down
as
required.
Note that
the
reed
dog
should
al-
ways
rest
upon
the
stop
screw
(84).
To
Set
the
Needle
Guard
The
function
or
the
needle
guard
(T4,Fig.21,
page
27)
is
to
prevent
the
needles
from
being
sprung
into
the
path
or
the
loop-
ers
when
the
loopers
are
on
their
forward
stroke.
The
needle
guard
should
be
set
as
close
as
possible
to
the
needles
but
with—
out
actually
touching
them.
To
set
the
needle
guard
in
the
correct
position,
loosen
the
set
screw
(Q4,Fig.21)
and
move
the
guard
to
or
from
the
needles
as
may
be
required,
then
securely
tighten
the
set
screw
(Q4).
The
needle
guard
can
also
be
adjusted
to
right
or
left
to
clear
the
feed
dog,
after
loosening
the
screw
(R4,Fig.21).

through
the
opening

Loosen
the
two
set
screws
(H4,Fig.23)
in
the
upper-feed
eccentric
(WZ),
also
loosen
the
two
set
screws
(04,
Fig.23)
in
the
under-feed
eccentric
(U2),
and
loosen
the
set
screw in the hub of the looper thread take-up (T3,Fig.23).
Take out the balance wheel cap screw, and loosen the two set
screws in the belt groove of the balance wheel, and remove the
balance wheel. Take out the three screws (J4,Fig.18, page 24) in
the rotary shaft flange bushing and remove this bushing.
NOTE - Some of the connections may bind slightly on the shaft
during removal of the shaft. It is therefore considered advis-
able to replace the balance wheel on the shaft and tighten the
two
set
screws
in
the
belt
groove
of
the
balance
wheel,
to
facil-
itate the removal of the shaft from the machine.

Litt
of
the
Feeding
Foot
The
lift
of
the
feeding
foot
is
controlled
by
the
adjustable
slide
in
the
needle
bar
crank
(MZ,Fig.25).
To
adjust,
turn
the
balance
wheel
to
bring
the
two
lock
screws
(L2,Fig.25),
in
the
face
of
the
needle
bar
crank
(M2), to
the
positions
shown
in
Fig.
25,
and
loosen
the
two
lock
screws
(L2).
In the
rear
of
the
needle bar
crank
(M2)
is
an
eccentric
ad-
justing
screw.
Turn
the
balance
wheel
to
bring
this
adjusting
screw
to
where
it
will
be
accessible
through
the
hole
(Q2,Fig.
26).
Turn
this
screw
to
the
right
for
less
lift,
or
to
the
left for
more
lift
of
the
feeding
foot.
The
foot
should
lift
just
high
enough
to
clear
the
work,
when
returning
for
the
next
feeding
motion.
When
adjustment
has
been
completed,
BE
SURE
to
firmly
tighten
the
two
lock
screws
(L2).
Less
feeding
foot
lift
is
practicable
when
sewing
light
ma-
terial
or
materials
with
no
seams
to
cross.
It is
desirable
to
limit
the
lift
to
the
minimum
required
for the
work
being
sewn,
as
this
permits
of
higher
speeds
without
noise.
The
length
of
time
that
the
feeding
foot
rests
upon
the
work
31
is controlled by loosening the clamping screw (P2,Fig.25) and
moving the feed bar up or down While the foot is off the work.
The
feeding
foot
must
remain
in
contact
with
the
work
throughout
the
feeding
motion,
with
the
result
that
the
upper
feed
bar
connecting
link
will
rise
about
3/64
inch
above
the
textolite
cushion
at
(02)
during
the
feeding
movement.
The
gap
at
(A6)
may
vary
accord-
ing to
the
length
of
stitch,
etc.
The
longer
the
stitch,
the
greater
the
gap,
while
a
short
stitch
re-
quires
correspondingly
less
gap.
Undue
noise
will
occur
should
the
gap
be
greater
than
actually
re-
quired.
