IDENTIFICATION
OF MACHINES
Each
UNION
SPECIAL
machine
is
identified
by a
Style
number
which
is
stamped
into
the
name
plate
on the
machine.
Style
numbers
are
classified
as
standard
and
special.
Standard
Style
numbers
have
one
or
more
letters
suffixed,
but
never
contain
the
letter
“Z”.
Example:
“Style
63400
A”.
Special
Style
numbers
contain
the
letter
“Z”.
When
only
minor changes
are
made
in
a
standard
machine,
a
“Z” is
suffixed
to
the Standard
Style
nuinber.Example:
“Style
63400
AZ”.
Styles
of
machines
similar
in
construction
are
grouped
under
a class
number
which
differs
from
the
style
number,
in
that
it
contains
no
letters.
Example:
“Class
63400”.

NEEDLES
(Continued)
To
have
needle
orders
promptly and
accurately
filled,
an
empty
package, a
sample
needle,
or
the
type
and
size number
should
be
forwarded.
Use
description
onlabel.
A
complete
order
would
read:
“1000
Needles,
Type
180
(IXS,
Size
080/O32’
Selection
of proper
needle
size
should
be
determined
by
the
size
of
the
thread
used.
Thread
should
pass freely
through
the
needle
eye
in
order
to produce a good
stitch
formation,
SELECTING
THE
SIZE
OF
THE
NEEDLE
The
strength requirement
of
the
seam
produced
is
largely
dependent
upon the
size
of
the
thread
employed,
The
following
table
shows the
preferred
size
of
needle
for
a
given
size
and
kind
of
thread.
The
choice,
however,
should
give
consideration
to
factors
referred to
above,
which
may
dictate
the
selection
of a
needle
size slightly
larger
or
smaller
than
the
size
specified.

IDENTIFYING PARTS
Where
the
construction
permits,
each
part
is
stamped
with
its
part number.
Parts
too
small
for
a
complete
catalog
stamping
are
identified
by letter
symbols
which
distinguish
one
part
from
another
that
is
similar
in
appearance.
Part
numbers
represent
the
same
part,
regardless
of
the catalog
in
which
they
appear.
IMPORTANT!
ON
ALL
ORDERS,
PLEASE

ORDERING
OF
REPAIR PARTS
ILLUSTRATIONS
The arrangement
of
this catalog
is to facilitate
easy
and
accurate
ordering
of
Class
63400
replacement
parts.
Six exploded
view plates
cover
the Standard
Styles
listed
in
this
catalog.
Each
plate
presents
a
sector of
the
machine,
parts
being
aligned
as
in
their
assembled
po
sition.
Small
keyline
views
show by a
blackended
area
exactly
where
the
parts
being
discussed
fit
in
the assembled
machine.
On the
page
opposite
the illustration
will
be
found
a listing
of the
parts
with
their
part numbers,
descriptions
and
the
number
of
pieces
required
in the
particular
view being
shown.
Numbers
in the first
column
are reference
numbers
only,
and merely
indicate
the
position
of
the
part
in
the
illustration.
Reference
numbers
should never
be used
in
ordering
parts. Always
use
the part
number
listed
in
the
second column.
Each
exploded
view
plate
carries
a reference
number for
each
part
for sale.
Sub—assemblies,
which
are sold
complete,
or
by
separate
part,
are
in
a
bracket
or
a
solid line
box
on
the
picture
plate.
Component
parts of
sub—assemblies,
which
can
be furnished
for
repairs,
are
indicated
by
indenting
their
descriptions
under
the
description
of the
main
sub—assembly. Example:

In those
cases
where
a
part
is
common
to all of
the machines
covered
by this
catalog,
no specific
usage
will
be mentioned
in
the description.
However,
when
the
parts
for
the various
machines
are
not
the same,
the
specific
usage
will
be mentioned
in
the description,
and, if
necessary,
the
difference
will
be shown
in the illustra
tion.
At
the
back
of the
book will
be found
a numerical
index of
all
the
parts
shown
in
this
book.
This will
facilitate
locating
the

when
only
the

is
known.

LUBRICATION
CAUTION!
Oil
has
been
drained
from
the
main
reservoir
before
shipment
and
the
reservoir
must
be
filled before
starting
to
operate.
Lubricate
machine
thoroughly,
in
accordance
with
instructions
which
follow,
and
run
slowly
for
several
minutes
to
distribute
the
oil
to
the
various
parts.
Full
speed
operation
can
then
be
expected
without
damage.
RECOMMENDED
OIL
Usa
stainless
water—white
straight
mineral
oil
ofaSaybolt
viscosity
of
90
to
125
seconds
at 100
Fahrenheit
in
the
main
reservoir.
This
is
equivalent
to
Union
Special
specification
No. 175.
Fill
main
reservoir
at plug
screw
(B,
Fig.
2)
and
check
oil level
at
gauge
(C);
oil
is
at
maximum
level
when
needle
is
in
yellow
band
marked
“full”.
Oil
should
be
added
when
needle
is
in
yellow
band
marked
“low”.
It
is
recommended
that
a
new
machine,
or
one
that
has
been
out
of
service
for
an
extended
period,
be
lubricated
as
follows:
Remove the
end
cover
and
directly
oil the
bearings
of
the
needle
bar
link,
take-up
and its
lever
and
needle
bar,
Replace
end
cover
as no
further
hand
oiling
will
be
required.
CAUTION!
The
machine
is
provided
with
automatic
or
manual
head
mechanism
oil
control.
The
oil
control
dial
(D,
Fig.
2)
is
shown
inthe
automatic

position,
and
should

be
desired,
remove
locking
screw
(G,
Fig.

and
turn
dial

to
exposethe
manual
oiling
port.
Inthe
manual
oiling
position,
five
or
six
drops
of
oil should
be
introduced
into
the
oiling
port
twice
daily
-
preferably
at
starting
time
and
mid-day.
Oil
may
be
drained
from
main
reservoir
by
removing
plug
screw
(F,
Fig.
2).
OIL GAUGE
The
oil
gauge
is
set
at
the
factory
to
show
the
proper
oil level
in
the reservoir.
Should
an
adjustment
become
necessary,
the following
steps
should
be
followed:
1.
Place
the
machine
upright
on
a
level
table
or
bench.
2.
Remove
the
reservoir
plug
screw
(located
belowthe
handwheel
and
near
the
bottom
of
the
machine).
3.
Oil
should
be
added
or
removed
so
that the
oil level
is
approximately
1/8
inch
below
the
bottom
edge
of
the hole.
4.
Loosen
the
lock
nut
on
the
calibrating
screw,
and
turn
the
screw
left or
right
so
that
the
gauge
needle
rests
on
the
yellow
band
marked
“FULL”
on
gauge
(C,
Fig.

5.
Tighten
lock
nut
and replace
plug screw.
Lubrication
of
the
mechanism
below
the
cloth
plate
A
is
automatically
accomplished
through
the
feed
driving
shaft
(D,
Fig.

which
is
tubular.
Oil
is
introduced
into the
shaft
at
the
sprocket
end
by
means
of
an
oil
D

INSTALLING
AND
MAINTENANCE
OF
OIL
SIPHON
The
felt
in the
priming
cup
is designed
for
a
specific
purpose,
This
felt,
No.
666—237
is thin
and
relatively
dense
to
meter
the
flow
of
priming
oil
and
to prevent
the
entrance
of
air.
The
felt,
at the
intake
of
the
siphon,
keeps
the
siphon
clear
of
lint,
and
prevents
the
entrance
of
air
at
that
point.
A
newly
installed
siphon
starts
its
iiction
within
five
to
ten
minutes
after
the
machine
is
operating.
Ilowever,
it
may
be
forty
minutes
or
so
before
the
air
is removed
from
the
line
and
the
siphon
is in
full
operation,
X\’hen
a
customer
receives
a
new
machine,
it has
probably
been
turned
upside
down
in
shipping,
oil
has
accumulated
in
the
head,
and
the siphon
may
not be
primed.
It
will,
however,
automatically
reprirne
itself
when
run.
After
the
first
day
of
operation,
the
siphon
can
be
checked
by
inspecting
the
tygon tube
at
the
junction
visible
at
the
presser
foot
lifter
arm
to
be
sure
it is
full
of
oil.
The
siphon
may
also
bE
checked
by
‘emoving
the
head
cover
and
wetting
the
inlet felt
with
oil.
The
felt
should
dsibly
dry
out
as
the
oil
is
drawn
into
the
siphon.
If
the
siphon
felts
become
clogged
and
the
siphon
does
not
function
properLy,
change
the
felts
as follows:
To
change
the
inlet
felt,
remove
the
inlet
tube
with
the
tygon
tube
disconnected
only
lt
the
column
end.
Replace
the
felt
and
reassemble.
To
change
the
prime
cup
felt,
first
remove
the
access
plug’
screw
at
the
rear
of
the
column.
Remove
felt
with
a
tweezers.
Replace
with
a
new
felt
being
sure
the
feLt
is pushed
down
tightly
into the
prime
cup,

INSTRUCTIONS
FOR
OPERATORS
TI
I
READ
While
the
direction
of
the
twist
in the
bobbinthread
is
immaterial,
the
direction
of
the
hook
rotation
favors
the
use
of
a
left
twist
thread
in
the
needle,
To
determine
the
direction
of
twist,
grasp
a
short
length
of
thread
between
thumb
and
forefinger
of
each
hand,
Turn
the
thread
away
from
you
with
your
right
hand.
If
the
strands
unwind,
it
is
a
left
twist,
if
not,
it
is
a
right
twist,
REMOVING

may
be
readily
corrected.
The
purpose
of
the
bobbin
winder
is
to
assure
an
operator
of
a full
bobbin
at
all
times,
When
the
bobbin
