MACHINE

144w304

is

a

long

arm

machine

with

workrng

space

of

30

inches

at

the

right

of

the

needle

bar

and

is

used

for

stitching

on

automobile

and

for

similar

Iorge

work.

Otherwise

the machine

is

the same

as

144w204.

SPEED

The maximum

speed

recommended

for

these machines

is

1500

revo-

lutions

per

minute,

when

permitted

by

the

nature

of

the

material

being

sewn. The machines should

be

run

slower

than the maximum

speed

until the

ports

which

are

in

movable

contact

hove

become

glozed

by

their

action

on

each

other.

When

the machines

ore

in

operation,

the

machine

TO

CHANGE

THE

AMOUNT

OF

LIFT

OF

THE

ALTERNATING

PRESSERS

The

heis.Jhl

of

lift

of

the

pressers

is

odjustable

by

moving

the link (F,

Fig.

to

ony

of

the

four

holes

in the

rock

shaft

crank.

The

maximum

lift

is

secured

with

the link in

the

bottom

hole.

The

amount

of

lift

should

be

reguloted

occording

to

the thickness

of

the

moteriol

being

sewn.

The

TO

ADJUST

THE

RELATIVE

HEIGHT

OF

LIFT

OF

THE

VIBRATING AND

LIFTING

PRESSERS

As a

rule,

the

vibrating

and

lifting

pressers

should

lift

on

equal

height,

but some

grades

of

work

may

require

that

they

lift

on

unequal

height.

To

change

the

relative

lift

of

the

presser

feet,

loosen

the

screw

(E, Fig.

3)

at

the

bock

of

the

machine

and

move

the

TO

REMOVE

THE

ARM

SHAFT

CONNECTION

BELT

FROM

WITHIN

THE

ARM

Slide the

connection

belt

off

the

lower

belt

pulley;

remove

the

machine

pulley.

loosen

the

three

screws

in the arm shaft bushing

near

the

machine

pulley'

and

remove

the bushing;

lift

the

belt

up

through

the

arm

cop

hole

as

far

as

possible

and

draw

it

out

through

the

space

normally

occupied

by

the bushing.

Owing

to

the

fact

that

the

sewing

hook

makes

two

revolutions

to

one

revolution

of

the

hook

driving

shaft,

and

that

the

feed

lilting

eccentric

is

on

the

hook

driving

shalt, it

is

possible

to

have

the

sewing

hook

correctly

timed

without

having

the

feed

correctly

timed.

To

overcome

this, the

plate

(F2, Fig. 24)

is

attached

to

the

underside

of

the

bed

of

the

machine. This

plate

is

marked

with

on

arrow

at

its

lower

end

and

directly

alongside

of

the

plate

is

the

collar

(G2,

Fig. 24)

mounted

on

the

hook

shalt,

which

is

also

marked

with

an

arrow.

Alter

replacing

the

belt

over

the

upper

pulley,

replace

the

arn1

shalt bushinq

and

securely

fasten it in

position

by

its

three

screws;

replace

the machine

pulley.

With

the

belt

on

the

upper

pulley,

turn the

machine

pulley

from

you

until the

thread

toke- up

lever

is

at

its

highest

point.

Then turn the

hook

shalt

with

the

fingers

until the

two

arrows,

one

on

the

plate

(F2)

and

the

other

on

the

collar

(G2),

ore

directly

in line.

Now,

without

disturbing

either

the arm shaft

or

the

hook

shaft, slip the

belt

over

the

lower

pulley.

The

feed

will

then

be

correctly

timed

with

the

needle
