Needles

Needles for Machines 95-SO and 95-100 are of Class and Variety
S8 X 1, and are furnished In Sizes 9, 11, 13, 14, 16, 17, IS, 19
and 21.

The size of the needle to be used should be determined by the
size of the thread which must pass freely through the eye of the

needle. Rough or uneven thread, or thread which passes with dif
ficulty through the eye of the needle, will interfere with the

successful use of the machine.

Orders for needles must specify the QUANTITY required, the

SIZE NUMBER, also the CLASS and VARIETY NUMBERS separated by an x.

The following Is an example of an Intelligible order;

"100 No.16, 88 X 1 Needles"

The best stitching results will be obtained by using the

needles furnished by the Singer Sewing Machine Company.

Thread

Left twist thread should be used in the needle,

Either right

or left twist thread can be used in the bobbin.

Fig.8. How to Determine the Twist

Hold the thread as shown above. Turn the thread over toward

you between the thumb and forefinger of the right hand; If left
twist, the strands will wind tighter; If right twist, the strands

will unwind.

It: slack: fГОШ the hand to the needle^ turn the balance wheel over

Fig.16. Drawing Up the Bobbin Thread

toward you until the needle moves down and up again to its highest

point, thus catching the bobbin thread; draw up the needle thread
and the bobbin thread will come up with it through the hole in the
throat plate (see Fig.16). Lay both threads back under the pres­ser foot.

To Commence Sewing

Place the material beneath the presser foot, lower the presser

foot and commence to sew, turning the balance wheel over toward

you. ■ .

To Remove the Work

Let the thread take-up lever rest at its highest point, raise
the presser foot, draw the work back and cut the threads close to
the goods.

Tensions

For ordinary stitching, the needle and bobbin threads should

be locked in the center of the thickness of the material, thus:

Fig.17. Perfect Stitch

If the tension on the needle thread Is too tight, or If that
on the bobbin thread Is too loose, the needle thread will lie
straight along the upper surface of the mterlal, thus:

Fig.18. Tight Needle Thread Tension

If the tension on the bobbin thread is too tight, or If that

on the needle thread Is too loose, the bobbin thread will lie

straight along the under side of the material, thus:

Fig.19. Loose Needle Thread Tension

To Regulate the Tensions

THE TENSION ON THE NEEDLE THREAD SHOULD BE REGULATED ONLY

WHEN THE PRESSER FOOT IS DOWN. Having lowered the presser foot,

turn the small thumb nut (C,Flg.2), at the front of the tension

discs, over to the right to Increase the tension. To decrease

the tension, turn this thumb nut over to the left.

The tension on the bobbin thread Is regulated by the large

screw (FF,Fig.ll) In the tension spring on the outside of the
bobbin case. To increase the tension, turn this screw over to
the right. To decrease the tension, turn this screw over to the
left.

When the tension on the bobbin thread has been once properly
adjusted. It Is seldom necessary to change It, as a correct stitch
can usually be obtained by varying the tension on the needle

thread.

14

To Regulate the Length of Stitch

The -length of stitch is regulated by the thumb screw (B,Flg.

2) in the slot on the front of the upright part of the arm. To
lengthen the stitch, loosen this thumb screw and move it down

ward. To shorten the stitch, loosen this thumb screw and move

It upward. When the desired length of stitch has been obtained,

tighten the thumb screw (B).

To Regulate the Pressure bn the Material

The pressure on the material Is regulated by the thumb screw
(D,Flg.2) . To Increase the pressure, turn this thumb screw over
to the right. To decrease the pressure, turn this thumb screw
over to the left.

To Set the Needle Bar at the Correct Height

See that the needle Is pushed up into the needle bar as far

as It will go, then remove the face plate.

The needle bar,
which is in the machine
when shipped from the
factory, has two timing

marks near its upper

end. Rotate the bal
ance whee1 unt i1 the
needle bar moves down

to its lowest position.
The UPPER TIMING MARK
on the needle bar
should then be centered
with the lower end of
the needle bar bushing,
as shown at (D) in Fig.

20. In case the needle
bar is not set at the
correct height, loosen

screw (E,Flg.20) and
move the needle bar up
or down until the UPPER
TIMING MARK is centered
with the lower end of
the needle bar bushing,
as shown at (D,Fig.20),
then securely tighten
screw (E).

Fig.20

Needle Bar Set at Correct Height

In the event that
the setting of the
needle bar bushing has

been disturbed, thus making it impossible to set the needle bar

for correct height by centering the upper timing mark with the

lower end of the needle bar bushing, turn the balance wheel to

bring the hook point to the center of the needle, loosen screw

(E) and move the needle bar up or down to bring the top of the
needle eye 1/32 inch below the point of the hook, then securely
tighten screw (E). Loosen the needle bar bushing set screw at
the top of the machine arm and, while the hook point is at the
center of the needle and 1/32 inch above the top of the needle
eye, move the needle bar bushing up or down to bring its lower

end exactly even with the LOVER TIMING MARK on the needle bar,

then securely tighten the needle bar, bushing set screw.

17

To Time the Sewing Hook

Remove presser foot, slide plate, throat plate and bobbin

case. Take out the two screws (E2,Flg.20) and remove feed dog.

Fig.21. Needle and Sewing Hook Correctly Timed

To determine that the hook Is correctly timed, place a new
needle In the machine, then turn the balance v^eel over toward
you until the LOWER TIMING MA.RK on the needle bar Is centered

with the lower end of the needle bar bushing as shown at (Q,Flg.

21)vWhen the needle bar Is on Its upward stroke. With the
needle bar In this position, the point of the hook should be at

the center of the needle as shown at (R,Flg.21). The Inset In
circle at the left of Fig.21 plainly shows this position of the
hook point relative to the needle.

18

In case the hook is not correctly timed, loosen the three

screws (L,Flg.22) In the hub of the hook. These three screws

can be reached from the top of the machine bed through the open-

Ing left by the removal of the throat plate, although, for pur

poses of Illustration, the screws are shown only In the view of

the underside of the machine In Fig.22. Rotating the balance
wheel of the machine will bring these screws, one at a time,
directly under the throat plate opening where they can be easily
reached with a screwdriver from the top of the machine bed.

After loosening the three screws (L,Flg.22) turn the hook on

Its shaft to bring the point of the hook at the center of the
needle as shown at (R,Fig.21), then tighten the three screws (L,
Fig.22).

The hook should be set as close as possible to the needle

without touching. If the hook Is too close to the needle or too
far away from It, loosen the three screws (L,Fig.22) and the bush
ing screw (J,Fig.22) and drive the bushing (K,Fig.22) In or out,

as may be required, until the hook Just clears the needle, being
very careful not to damage the bushing, then securely tighten the
bushing screw (J) and the three screws (L).

the hub of the hook, then turn the balance vdieel over toward you
until the feed bar (S,Fig. 23) is raised to its highest point.
Turn the sewing hook until the thread guard (U,Fig.23) is at the
bottom, as shown in Fig.23, and turn the bobbin case holder (P,

Fig.23) until it is in the position shown in Fig.23. The sewing
hook can then be removed from the hook shaft.

When placing a new sewing hook on the shaft, have the thread

guard (U) of the hook at the bottom and the bobbin case holder

(P) turned to the position shown in Fig.23, so that the hook will
clear the feed bar (S).

When the hook is in position on the shaft, turn the bobbin
case holder (P,Fig.23) until the notch (T,Fig.23) is at the top,
then replace the bobbin case holder position bracket (H,Fig.22)
being careful to see that the position stud (M,Fig.22) enters the

notch at the top of the bobbin case holder, as shown in Fig.22,

20

then securely fasten the position bracket by means of the screw

(G,Fig.22). Replace the needle and time the sewing hook as In

structed on pages 17 and 18. When tightening the three screws

(L,Fig.22) In the hub of the hook, draw the hook shaft toward the
needle bar end of the mchlne and press the hook toward the bal
ance wheel to take up the end play In the shaft. Then replace

the bobbin case and slide plate.

To Remove and Replace the

Sewing Hook Shaft

Remove the sewing

hook as Instructed on

page 19. Take out
the screw (V,Flg.24)

and remove both sec

tions of the gear

case (V,Fig.24), then
wipe the grease away
from the gears.

Before removing

the hook shaft (X,Flg.

25) from the machine,

the gears (Y and Z,
Fig.25) should be

marked with chalk or
red pencil on one of

the teeth of the gear

(Y) and the space of
the gear (Z) In which
the marked tooth

meshes. This Is Im

portant, as the gears

may become dislodged
when removing the

hook shaft, and the

marks will enable you
to retain the origin

al relative positions

Fig.24. Vlev^k of Underside of №chlne of the gears.

Showing Gear Case

To remove the hook shaft, loosen the two set screws in the

gear (Y,Fig.25), then insert the new hook shaft Into the gear

SI ■

(y), from the right hand end, pushing thp old shaft out of the

gear toward the needle bar by means of the new shaft, as shown

Fig.85. Removing and Replacing Sewing Hook Shaft

In Fig.25. By removing the old shaft In this manner, the rela

tive positions of the gears (Y and Z) will not be disturbed.

When placing the new shaft In position In the machine, see that

the flat portion near one end of the shaft Is at the right so

that one of the set screws In the gear (Y,Flg.25) will bear
against It when the gear Is fastened In position on the shaft.
The shaft should be set so that Its left end Is flush with the
front (left hand) side of the body of the sewing hook.

When the shaft Is correctly positioned, securely tighten the
two set screws In the gear (Y), making sure that one of these two
screws bears against the flat portion of the shaft.

Time the sewing hook as Instructed on pages 17 and 18.
Replace the gear case and securely fasten It In position by

means of the screw (V,Flg.24).

22

To Adjust the Thread Take-up Spring

The thread take-up spring (Ci2,Flg.26) should be set so that

when the eye of the needle reaches the goods on the downward

Fig.26. Adjustment of Thread Take-up Spring

stroke of the needle bar, the spring will be through acting and

will rest against the stop on-the thread take-up spring regulator.

If the thread take-up spring Is not correctly set, as Instructed
above, loosen the set screw (R2,Flg.26) In the arm of the machine,
and turn the tension stud (S2,Flg.26) to the right for more move

ment of the spring or to the left for less movement. When the
spring Is-correctly set, securely tighten the set screw (R2).

The tension on the thread take-up spring (Q2) Is regulated

by turning the tension stud (S2) to the right to Increase the

tension, or to the left to decrease the tension. The tension on
the thread take-up spring should be just sufficient to take up
the Slack of^the needle thread until the eye of the needle
reaches the goods In Its descent.

Timing of the Feeding Mechanism

When the machine leaves the factory, the feed eccentric Is

correctly set by having the timing screw In the eccentric enter

the groove In the arm shaft. If, for any reason. It may be nec

essary to alter the timing of the feed eccentric, loosen the

timing screw and the set screw, turn the eccentric as required

tighten the set screw only.
