THE SINGER MANUFACTURING CO.

by The Singer Manufacturing Co.

THE Singer Electric No. 20-2 machine is a

practical, convenient sewing machine made

especially for children. It is simple and safe to

operate and will do real sewing on dolly's

wardrobe, or even on repairs to the grown-

ups' clothing and other household articles.

All the electrical parts of the motor are com-

pletely inclosed in the bakelite shell, so that

there is no danger of electrical shock. The

motor requires no attention, except occasion-

al oiling. It must be used only on 110 volt, 60

cycle, alternating current (A.C.).

To Start the Motor

Place the plug on the rubber-covered cord

into a wall outlet or light socket. (Be sure that

your currently is 110 volt, 60 cycle).

Press down on the switch (R, Fig. 2)

and the lever (S) at the same time; this will ill

start the motor. Release the lever, and the

rubber roller back of the hand wheel will

touch the rim of the wheel and drive the

machine.

To Stop the Motor

Push down on the switch (R), the same as for

starting. When through sewing, pull the plug

out of the electric outlet, and wrap the cord

around the machine.

Do not run the machine

or motor except when sewing.

To Change the Speed

Two sewing speeds are provided; a slower

speed for careful work, or for young children,

and a faster speed for ordinary straight work.

To change to a different speed, remove the

guard (X, Fig. 3) over the motor pulley by

pressing it downward and sliding it back.

For the slow speed, move the belt to the out-

side grooves (V) in the two pulleys, as shown

in Fig. 3. For the faster speed, move the belt

to the inner grooves (W) in the pulleys. Be

careful not to stretch the belt.

Then replace the guard with it two slots over

the metal tabs in the base, press it down and

forward into place.

If the motor stalls or the rubber roller slips on

the hand wheel, it is because the work being

sewn is to heavy for the machine.

If the rubber roller or the rubber belt should

slip when doing ordinary sewing, they may

have become hard and brittle with age and

should be replaced.

Needles and Thread

Needles for the Machine No. 20-2 are of Class and Variety 21x1 and four of these needles of

size 14 are furnished with each machine. Finer or coarser needles, as shown below, can be

purchased from any Singer shop or Singer salesman.

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 to ensure the successful use of the machine.

To Insert a Needle

Turn the hand wheel (Q, Fig. 2) over from

you until the needle bar (M, Fig. 2) moves up

to its highest point. With the screwdriver,

loosen the set screw (G Fig. 2) in the lower

end of the needle bar, take out the old needle

and put the new needle up into the bar as far

as it will go, with its flat side toward the right

and the long groove in the needle at the left,

then firmly tighten the set screw (G).

To Thread the Needle

(SEE FIG. 4)

Turn the hand wheel over away from you until

the needle moves up to its highest point.

Place the spool of thread on the spool pin,

pass the thread from the spool toward you

through the two holes (! and 2) in the thread

pull-off, to the left and down through the hole

(3) in the nipper lever. Draw the thread to the

left under the end of the nipper lever and

pass it over between the tension discs (4), up

though the hole (5) in the machine, from right

to left through the hole (6) near the upper end

of the needle bar, down and from left to right

through the eye of the needle. Draw about

two inches of thread through the eye of the

needle with which to commence sewing.

To Commence Sewing

Raise the presser foot (E Fig 2) by turning up

the presser bar lifter (K, Fig 2). Place the

material beneath the presser foot and lower

the presser foot. Lay the forefinger of the left

hand gently on the end of the thread and turn

the hand wheel (Q, Fig. 2) over from you in

the direction indicated by the two arrows on

the hand wheel, until the first stitch is made.

Then place the end of the thread back under

the presser foot and commence to sew.

To Remove the Work

Sew two stitches past the end of the seam

and stop the machine with the needle bar at

its highest point, then with the left hand draw

a finger length of thread to the left through

the hole near the upper end of the needle bar

as shown in Fig. 5. With the right hand,

using a pair of scissors, draw the slack thread

to the right through the eye of the needle, as

shown in Fig. 6, then pull the thread upward

from the work, the presser foot being down,

and cut the thread close to the goods, as

shown in Fig. 7. Raise the presser foot, pull

the work from you and the end of the thread

will be draw through the loop, as shown in

Fig. 8.

To Fasten Off the Stitching in the Work

When it is necessary to fasten off the last

stitch in the work, stop the machine with the

needle in the work, place the fingers on the

material close to the presser foot to prevent

the work from moving, raise the presser foot

and take one more stitch in the last hole

made and stop the machine with needle bar

at its highest point; then with the left hand

draw a finger length of thread to the left

through the hole near the upper end of the

needle bar as shown in Fig. 5. With the right

hand, using a pair of scissors, draw the slack

thread to the right through the eye of the nee-

dle as shown in Fig. 6; then pull the thread

upward from the work and cut the thread

close to the goods as shown in Fig. 7. Pull

the work from you and the end of the thread

will be draw through the loop as shown in

Fig. 9.

To Change the Length of Stitch

The length of stitch is regulated by the same

lever (A, Fig. 2) under the cloth plate. To

make a longer stitch, move this lever away

from you. To make a shorter stitch, move the

lever toward you.

THE END OF A SEAM

FIG 9. STITCHING FASTENED OFF IN THE WORK

To Regulate the Tension on the Thread

The tension on the thread is automatic and

seldom requires changing. When the needle

is at its highest point, the nipper lever (3, Fig.

4) is raised and the tension on the thread is

released so as to allow the needle bar to

draw off sufficient thread for the next stitch. If

the stitches are so tight that they pucker the

material, loosen the tension by turning to the

left the thumb nut (O, Fig. 2) at the front of

the tension discs. If the stitch is too loose,

tighten the tension by turning the thumb nut

to the right.

To Use the Cloth Guide

To guide the work accurately when sewing

close to the edge of the goods, the cloth

guide (H, Fig. 2) should be used. Fasten the

cloth guide to the cloth plate of the machine

by means of the clamping thumb screw (J,

Fig. 2), inserting the thumb screw into the

screw hole in the cloth plate. The cloth guide

can be adjusted to bring the edge of the

goods as close to the line of stitching as

desired. If desired, the cloth guide can be

removed from the machine.

To Oil the Machine

The machine should be oiled occasionally

with the sewing machine oil especially pre-

pare by the Singer Sewing Machine

Company. This oil can be purchased from

any Singer shop or Singer salesman. Apply

one drop of oil at each of the places where a

part of the machine moves against another

part.

About every six months, put a drop or two of

CAUTION

Do not run the machine or motor except

when sewing.

When the machine is not in use, always

remove the plug from the electric outlet or

light socket.

Further Instructions

for the use of this machine or any other

Singer Machine, will be cheerfully given at

your local Singer Shop.
