IDENTIFICATION OF MACHINES
Ea ch Union Special machine is identif i ed by a Style number on a name plate on
the machin e. St yl e numbers are classified as standard and special. St andard Styl e
numbers hav e on e or more letters suffixed, but never contain the letter "Z".
Example: "Style 39500 FW". Special Style numbers contain the letter "Z". When
only mino r changes are made in a standard machine, a "z" is suf fi xed to the stan-
dard Style number. Example: "Style 39500 FWZ".
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

wh i ch may hav e en te red the crank case. It should be removed and cleaned periodi-
cally.
NEEDLES
Each Union Sp e cial Needle has both type and size number. The type number
denotes t he kind of shank, point. length, groove. finish and other details. The siz e
number. stamp ed on the needle shank. denotes largest diameter of blade, me asur ed
in thousandths of an inch, midway between sha11k and eye. Collectively, type and
size number repr e sent the complete symbol wh i ch is given on the labe l of a ll nee -
dles packaged and sold by Union Special.
Class 39500 machines use a curved blade needle. The standard recommended
needle for the machine covered in this catalog is Type 154 GAS. Below is the des-
cription and sizes available of the recommended needle.
Type No.
154 GAS
Description and Sizes
Round shank, round point, curved blade, standard length, single groove,
struck groove, spotted, chromium plated and is available in sizes 022,
025, 027, 029, 032, 036, 040, 044, 0•19, 054.
To have needle orders promptly and acc u rately filled, an empty package, a
sample needle, or the type and size number should be forwarded. Use description
on label. A complete order would read:
11
1000 Ne edles, Type 154 GAS, Size 036 ".
Selection of proper needle size is determined by size of thread used. Thread
should pass freely through needle eye in order to produce a good s ti tch formation.
Success in the operation of Union Speci al ma chines can be secured only by use
of needles pac k aged under our brand name, ~ • which is backed by a re-
putation for producing highest quality needles in materials and workmansh ip for
more than three- quarters of a century.
CHANGING NEEDLES
Release pressure on presser foot by turnin g presser foot release bush ing (AG,

THREAD STAND
After thread comes from cones on cone support (A, Fig. 1), the needle threads
are threaded through the back bar of the thread eyelet (B), under the middle bar and
through the center holes of the front bar. The looper threads come from the cones,
through holes of the middle bar from back to front and then through the two outside
holes of the front bar. Next it is threaded through the upper holes of tension thread
guide (C) front to back and then through the lower holes from back to front. The
threads continue between the tension discs (J), through tension post slot (K) in ten-
sion post (G) and on through front thread guide (M).
THREADING
Only parts involved in threading are shown in the threading diagram (Fig. 1).
Parts are placed in their relative positions for clarity.
It will simplify the threading of these machines to follow the recommended se-
quence of threading lower looper first, upper looper second, and the needles third.
Before beginning to thread, swing cloth plate open, turn handwheel in operating
direction until needles (X) are in high position, release pressure on presser foot by
turning presser foot release bushing (AG), and swing presser arm (U) out of posi-
tion.
Be sure the threads, as they come from the tension thread guide (C), are be-
tween the tension discs (J) and in tension post slot (K) in tension post (G). The
tension posts should be positioned so the tension post slot will be at the approximate
angle for the different threads as indicated in Fig. 1.
TO THREAD LOWER LOOPER
Double end of thread and lead it through both eyes of lower looper thread eye-
let (R, Fig. 1) from right to left. NOTE: Thread must pass in front of looper thread
pull- off (AF). Lead thread behind fabric guard (S) and through hole of frame looper
thread guide (T). Turn handwheel in operating direction until heel of lower looper
(V) is all the way to the left; then thread through both eyes from left to right. Left
eye of lower looper can be threaded easily if tweezers are in left hand.
TO THREAD UPPER LOOPER
Turn handwheel until point of upper looper (W) is all the way left. Lead thread
through auxiliary looper thread eyelet (P) from back to front, then through both
eyes of upper looper thread eyelet (N) from left to right. NOTE: Thread must pass
in front of looper thread pull-off (AF). After pulling up upper looper thread tube
assembly (AA), lead thread under neck of top cover casting and down through thread
tube assembly (AA). Pull thread out bottom of tube; push tube down, then insert
thread through upper looper eye from front to back.
CAUTION! Be sure upper looper thread is under lower looper thread when
passing from tube assembly to upper looper eye.
TO THREAD THE NEEDLE
Turn handwheel in operating direction until needles (X, Fig. 1) are in their
highest position. Insert needle threads from right to left, through both eyes of nee-
dle thread eyelet (AD), under neck of top cover casting; and then down through holes
in top cover needle thread eyelet (AC). The right needle thread should be threaded
through the right hole and the left needle thread through the left hole of the top co-
ver needle thread eyelet. Thread needles from the front.

THREAD TENSION
The amount of tension on needle and looper threads is regulated by the tension
nut (D, Fig. 1). Tension on threads should be only enough to secure proper stitch
formation.
PRESSER FOOT PRESSURE
Sufficient presser foot pressure to feed work uniformly
should be maintained. Should it be necessary to i ncrease or
decrease amount of pressure on presser foot, loosen lock
nut (A~ Fig. 2) and turn adjusting screw (B). Adjusting
screw has a right hand thread so tightening increases pres-
sure, loosening decreases pressure. When pressure adjust-
ing screw (B) has been properly set, tighten lock nut (A).
With presser foot resting on throat plate, position locking
nut (C) so that its under surface is approximately 1/3 2 inch
to 1/16 inch from the top surface of adjusting screw (B).
Set cap (D) against locking nut (C).
FEED ECCENTRICS
Fig. 2
Feed eccentrics used in Style 39500 FW machines have been selected to produce
approximately 10 stitches per inch. It will be noted that the part number of main
feed eccentric is No. 39540 B-12 while that of differential feed eccentric is No.
39540 B-10. Minor numbers of the part symbol indicate approximately the number
of stitches obtainable when using that eccentric. Unless otherwise specified, rna-
chine will be shipped with above combination of eccentrics.
Generally speaking, differential (right hand) feed eccentric determines number
of stitches produced; main (left hand) feed eccentric is selected in relation to de-
gree and direction of stretch of material being sewn, or type of operation.
Following stitch number feed eccentrics are available under No. 39540 B- 4,
-5. -6. -7, -8, -9,-10,-11,-12,-13,-14,-15,-16,-18,-20,-22,-24,-26,-28,-30,-32,
-34, -36, -40. Only two eccentrics are supplied with each machine. Additional
eccentrics may be ordered separately. To order an eccentric, use No. 39540 B
with a minor number suffixed to indicate number of stitches desired. Example:
11
39540 B-12".
ASSEMBLING AND ADJUSTING SEWING PARTS
Before assembling and adjusting sewing parts, remove cloth plate, fabric
guard, chip guard, upper knife assembly. lower knife holder assembly. then follow
this suggested sequence:
Fig. 3
SETTING THE NEEDLE
With throat plate assembled in position, needles
should center in th e front end of needle slots. When
needles are at hi gh position, needle points should be
set 31/64 inch above throat plate (A, Fig. 3). To
align needl es or set the height above the throat plate,
move needl e dr i ving arm (B. Fig. 3) by loosening
clamp screw (C). Remove throat plate, after needle
has been set pr operly and clamp screw (C) has been
tighten.

SETTING THE NEEDLE (Continued)
If needle thread cam pull-off (A, Fi g. 4) ov er -
laps looper thread pull- off (B), separate by movin g
looper thread pull- off back. When retightening loo -
per pull- off sc r ew, be sure to take up end play in
needle driving arm.
At this point. insert lower looper (A. Fig. 5)
into bar (B). Wi th lower looper at left end of its
stroke. set looper point 1/16 inch fr om the center of
left needle (Fig. 5), using looper gauge No. 21225-
1/16. Do not have lower looper deflecting needle.
Tighten nut (C).
Now assemble differential (front) feed dog.
SETTING THE REAR NEEDLE GUARD
Set rear needle guard (A. Fig. 6) as high as
possible. without interfering with either lower looper
or movement of lower knife holder. but still in posi-
tion to deflect needles forward . 002-. 004 inch. Screw
(B) is used to set rear needle guard. Make sure there
is no interference between rear needle guard and low-
er looper.
SETTING THE LOWER LOOPER
Now finish lower looper adjustment. As lower
looper moves to the right. its point should be set into
the scarf of the left needle (A, Fig. 7) until the needles spring
forward from rear guard surface another . 002-. 004 inch.
SETTING THE FRONT NEEDLE GUARD
Assemble front needle guard (C. Fig.
6). When lower looper is springing nee-
dles off rear needle guard. set front nee-
dle guard as close as possible to needle
without touching. Screw (D) is used to ad-
just and set front needle guard. After this
setting make sure there is no interference
between needle guards and differential
feed dog.
SETTING THE UPPER LOOPER
Insert upper looper (A. Fig. 8) in its Fig. 7
holder. Screw (B) holds upper looper in its
Fig. 6 holder, and permits it to be pushed in or out. or turn ed a-
round its shank. Insert upper looper holder into upper looper
shaft, if it is not alr e ady in place. Screw (C) on clamp holds the upp er loop er hold-
in the shaft. Locate upper looper in its holder so that the shank extends 1/16 to 3/3 2
inch beyond holder.

SETTING THE UPPER LOOPER (Continued)
When the upp er looper is at the right end of its stroke,
upper looper hold er should be set to position upper looper
shank back of vertical (F i g. 8). Be sure there is a clearance
between heel of loop er and casting.
By adjusting looper holder in or out
of upper looper shaft and by turning the
loope r around its shank, set upper loo-
per point to cross lower looper to the
left of the lower looper eye with 0. 00 2
to 0. 004 clearance (Fig. 9).
Next, turn the handwheel until upper
looper is at the left end of its travel.
Check dimensions of upper looper point Fig. 8
with respect to the right needle and
Fig. 9
throat plate (Fig. 10). If resetting is necessary, do it by
moving the upper looper holder (A, Fig. 10). Figure 10 re-
presents the correct dimensional setting.
Dimension 17/32 inch is increased by turning upper looper
holder counterclockwise looking from left end of machine. Di-
mension 9/64 inch is increased by pulling upper looper holder
to the left, out of the upper looper shaft
11
After these changes
are made, it may be necessary to turn the upper looper around
its shank slightly to maintain the condition shown in Fig. 9.
When the correct setting is obtained, it
can be checked quickly as follows: As upper
looper is moving to the right and the upper
looper eye centers on the right needle, the
eyes of the upper looper and needle should
align exactly (Fig. 11).
Fig. 10
Check setting to avoid interference between upper loo p er
and needle on needle downstroke. If needle rubs the back of up-
per looper, pull looper out of its holder slightly and rotate loo-
per a short distance counter- clockwise, looking from left end of
machine. Reset to maintain dimensions of Figs. 9, 10, 11.
Fig. 11
SETTING THE FEED DOGS
Assemble the main and differen-
tial feed dogs (A, B, Fig. 12). Main
and differential feed dogs should be
leveled with respect to the throat
plate by rotating feed tilting adjusting
pin (C). This pin raises or lowers the
back end of the feed bar.
The feed dogs should be set level
at the time the teeth first appear above
the throat plate. Screw (D) locks feed
Fig. 12
tiltin g adjusting pin in place. With the feed dogs at their highest point of travel, the
top of the teeth on the main and differential feed dogs (A, B) should be 3/64 inch a-
bove the throat plate. The chaining feed dog is made as an integral part of the main
feed dog.

SETTING THE LOWER KNIFE
Replace lower knife holder assembly. Lower knife
(A, Fig. 13) should be set with cutting edge flush with
throat plate surface. Adjustments are made with hexa-
gonal head screw which holds lower knife. Lower knife
is spring pressed against upper knife, so no lateral ad-
justment is necessary when width of trim is changed.
Lower knife may be secured in any position by tight-
ening screw (B) and locking nut (C) against support
bracket. Because screw (B) also serves as latch pin for
the cloth plate latch spring, it should always be locked
with nut (C) even when screw is not tightened against
lower knife holder.
SETTING THE UPPER KNIFE
Replace upper knife assembly. Clamp upper knife
(D, Fig. 13) in position, setting nut (E) to hold clamp
(F) in its most clockwise position against upper knife.
Upper knife chain guard (J) should be positioned so that
the guarding section is approximately 1/64 inch behind Fig. 13
the cutting edge and in contact with the top surface of the
upper knife.
At the bottom of its stroke, front cutting edge of upper knife should extend not
less than 1/64 inch below the cutting edge of lower knife.
After upper knife has been set for the proper width of trim, screw (G) must be
tightened to lock the upper knife holding block (H) in place. This will simplify re-
setting when upper knife is replaced.
SETTING THE STITCH LENGTH
Length of stitch is determined by the combination of feed eccentrics used. Out-
er (left) eccentric (A, Fig. 14) actuates main (rear) feed dog; while the inner (right)
eccentric (B) actuates the differential (front) feed dog.
In assembling the feed eccentrics, be sure hubs
are facing each other. Be careful not to damage shaft
or key. Tighten nut (C) securely.
Fig. 14
To change feed
eccentrics, remove
nut (C) and washer
(D) from end of shaft
(E). Turn handwheel
in operating direc-
tion until key slot in
eccentric is toward
the front. Using hook-
ed eccentric extrac-
tor (F), supplied with machine, reach' behind
eccentrics as shown and withdraw eccentrics. It
may be necessary to move handwheel back and
forth slightly during extraction.
Fig. 15
If eccentrics are unusually tight fitting, in addition to removing nut (C) and
washer (D) (Fig. 15) from shaft (E), it may be helpful to remove nut (G) and feed
driving connection (H). Then continue as originally suggested.

SETTING THE PRESSER FOOT
Assemble the presser foot to presser arm. With needle in high position, swing
presser arm into sewing position and set the presser foot to align needle holes
(front and back) and flat on throat plate. The front edge of needle hole in presser
foot must be aligned with front edge of needle hole in throat plate. It is also impor-
tant that the bottom of the presser foot be flat on the throat plate. If necessary,
presser foot can be realigned with throat
plate slots by shifting the foot lifter lever
shaft (H, Fig. 16). To move the shaft, loosen
collar screws (B, Fig. 16) and clamp screw
(G) and then shift the foot lifter lever shaft to
the left or right as required. Retighten col-
lar screws and clamp screws.
The foot lifter lever arm (A, Fig. 16)
and the collar (B) secure the shaft. Be sure
the presser arm does not bind and rise when
presser foot release bushing is unlocked. To
center presser foot and stitch tongue with
respect to throat plate needle hole, loosen
presser foot hinge screw.
Fig. 16 Adjust lifter lever stop screw (C) so that
presser foot can be raised no higher than
upper looper will permit: then lock the nut (D). To find this maximum safe position,
turn the handwheel so point of upper looper is directly over presser foot tongue.
Raise presser foot by depressing the presser foot treadle and manually lower the
toe of presser foot. Height adjustment is correct if presser foot tongue does not
contact the upper looper. There should be from 1/16 to 1/8 inch free motion of foot
lifter lever before the presser foot begins to rise. This adjustment is made with
screw (E) and locked with nut (F).
Re-assemble chip guard, fabric guard and cloth plate. To make assembly of
chip guard easy, turn handwheel until upper knife assembly reaches its highest
position.
STARTING TO OPERATE
Be sure machine is threaded according to threading diagram (Fig. 1). With
thread tensions light, set looper thread eyelets (N and R, Fig. 1) about horizontal
and in the middle of their front to back locations. Operate machine slowly, without
presser foot in place, to make sure that chain forms and moves off the tongue
freely. Swing presser foot into position, insert material, and sew slowly.
NEEDLE THREAD CONTROL
While sewing on material, check needle thread control as follows: Usually all
needle thread is drawn on needle down stroke. At top of needle stroke, thread
should be just tight enough to feed chain off stitch tongue. Stitch tends to pull down
slightly if excessive thread is pulled on the up stroke. With needle at bottom of
stroke, position needle thread eyelet (AD, Fig. 1) so that needle cam pull-off (AE)
just contacts needle thread.

From the library of: Superior Sewing Machine & Supply LLC

LOWER LOOPER THREAD CONTROL
With material under presser foot, set lower looper thread eyelet (R, Fig. 1)
back far enough so thread is a little slack when looper thread pull- off (AF) reach es
its most rearward position. Looper thread pull-off (AF) is set about 1/8 inch dis -
tance behind needle thread cam pull- off (AE). Frame looper thread guide (T) should
be set with its eyel et approximately 1/8 inch to the right of lower looper (V) heel
eyelet at the time lower looper is at extreme left end of its travel.
While sewing on material, check drawing off of looper thread as follows: A
portion of lower looper thread should be drawn through the tension before lower
looper thread comes off upper looper. To increase amount of thread drawn through
the tension while lower looper thread is on upper loope r , move lower looper th r ead
eyelet (R) down, keeping the same amount of pull- off action.
UPPER LOOPER THREAD CONTROL
Before proceeding to adjust upper looper thread eyelet (N, Fig. 1) balance all
four tensions to give a normal appearing stitch. Moderate change in these tensions
will not markedly effect the purl.
During needle down stroke, forward stroke of looper thread pull-off (AF) will
draw upper looper thread through the tension. When normal amount of looper thread
is drawn, upper looper thread will have almost all slack taken up as looper thread
pull- off reaches its most rearward position.
POSITIONING THE PURL
To move the purl more under the edge, both looper thread eyelets (N and R,
Fig. 1) should be raised keeping the same amount of pull-off. Usually it is better
to have slightly more pull-off on upper thread than on lower thread.
If it becomes necessary to move looper thread pull- off (AF), be sure to take up
all end play in needle drive shaft before tightening. If upper looper is located so
that it is higher over throat plate than recommended in (Fig. 10), the purl will tend
to form near the top edge. If upper looper is too low, the purl will form nearer the
bottom edge.
THREAD TENSIONS
The needle thread tension required is a function of needle thread and material
being sewn. In general, lower looper thread tension should be set as high as possi-
ble without causing needle thread to be pulled down. Upper looper thread tension
should be increased as long as the elasticity of the chain increases, or until the
purl is pulled too far over the top.
