Description
Machine 1200-1 is especially suited for dress-
makers and homeindustrial use. Itis used on Table
1(K)027 and Stand 46913, as shown on page 1,andis
fitted with a knee lifter for raising and lowering the
prosper foot.
The machine is driven byan electricmotor built
on the back ofits arm, and controlled bya treadle.
An electric Singerlight is also built on the armto
throw light onthe work.
The machine hasa horizontal rotary sewing hook
and makes the lock stitch. 7t has reverse feeding
mechanism by means of which the machinestitches
as readily ina reversedirection asit does ina for-
ward direction.

The knee plate (D, Fig. 3)maybe moved upor
down to suit the operator after loosening the set
screw (E). It maybe swung tothe right or left
after loosening theset screw in the hub (B).
The stop (C) should be set so that the knee lifter
cannot raise the presser barany higher than itis
raised by the hand lifter (A, Fig. 2),in order to pre-
vent strain onthe tension relea.se mechanism. Thc
rear stop (F, Fig. 3) should permit a little loose
motion ofthe knee lever after the presser foot has
beenlowered tothe throat plate.

r
Motor Canbe Operated on Either Alternating
Current or Direct Current
The electric motor, which is located atthe back
of the machine, canbe operated on either alternat-
ing current or direct current, as desired. The
standard windings ofthe motor arefor110 volts,
but motors canbe furnished for any voltage be-
tween 100and 250.
Special motors for32 volts direct current, and
for oO voltsalternatingcurrent and directcurrent,
have also been developed andare available.
Points to Determine Before Connecting
Motor to Electric Service Line
Obtain the following information from the Elec-
tric LightCompanywhich supplies the electric
current forthe circuit to which the motor isto
be connected:
1. If current is direct, what isthe voltage? The
voltage range stamped on the nameplate ofthe
motormustcorrespond to that ofthe circuit.
2. If current is alternating, in addition to the
voltage,what isthe number of cycles? The number
of cyclesstamped en the name plate ofthe motor
mustcorrespond to that ofthe circuit.
The voltage ofany circuitand, if alternating
current, the number of cycles, canbe verified by
looking at the name plate on service watt meter
installed by the local Klectric Light Company.
To Connect the Machine to
Electric Service Line
Push the terminal plug atoneendofthe electric
cord asfarasit will goonthe three-pin terminal
block atthe right ofthe machine, as shown in
Fig. 7. Attach the plug atthe other endof the
cord tothe nearest electric outlet and the machine
is ready for operation.
To Insure Perfect Action of the Machine
When turned by hand, the balancewheel must
always turn overtoward the operator.
Donotrunthe machine with the prcsser foot
resting onthe feed withoutclothunder the presser
foot.
Donotrunthe machine when both bobbincase
and needle arc threaded, unless there is material
under the presser foot.
Donottryto help the machine by pulling the
fabric, lest you bend the needle. The machine feeds
the work without assistance.
The slideover the bobbin case should be kept
closed when the machine isin operation.
CAUTION
When you have finished your sewing,alwaysdis-
connect the plug from the electric outlet.

r
Singerlight
To turn the Singerlight "on" or "off", a switch is
conveniently located atthe front of the three-pin
terminal block, as shown atD, Fig. 7.
To Remove and Replace the Bulb
Do not attempt to unscrew the bulb. Itisofthe
bayonet and sockettype and does not unscrew.
Fid. 4
To Remove the Bulb. Press the bulbinto the
Singarlight socket andatthe sametimeturn the
bulbover toward the machine asfarasit will go,
then withdraw the bulb.
To Insert a New Bulb. Press the bulbinto the
Singerlight socket and turn it over from the machine
until the bulb pin(A, Fig. 4) enters the notch inthe
socket, as shown in Fig. 4.
To Operate the Machine
Raise the presser foot (B)by means of the presser
bar lifter (C)to prevent injury tothe foot (B)and
feed (A).
I-'IG. 5.END VIEW IIF THE MACHINE
Place a piece of clothunder the presser foot and
let the foot downupon it.
Turn on the electric current and depress the
treadle. Asthe pressure on the treadle is increased,
the speed of the machine is increased, the speed
being controlledentirely bythe amount of pres-
sure onthe treadle.Operate the machine hi this
way, without being threaded, until you have be-
come accustomed to guiding the material and
operating the treadle.

r
To Remove the Bobbin
Draw tothe left the slide inthebedofthema-
chine and lift outthe bobbinwith the thumb and
forefinger ofthe left hand, as shown in Fig. 6.
FIG. C>. HEMOVIXG THE ROBBI\o Wind the Bobbin
Itis necessary to understand the stop motion
(C, Fig. 7}by which the balancewheel (B, Fig. 7)
canbe released when required, thuspermitting the
winding of bobbinswithoutrunning the stitching
mechanism.
Release the balancewheel by turning the stop
motion screw (C) overtowardyou. It is necessary
to hold the balance wheel while loosening the stop
motion screw.

Place the bobbin onthe bobbinwinderspindle
und push itup closelyagainst the shoulder, having
FIG. 7. WINDING THE BOBBIN
the small pininthe shoulder enter the hole inthe
side ofthe bobbin. Putthe spool of thread onthe
spool pin (1). Draw the thread under and between
the tension discs (2)onthebedofthe machine,
then pass the thread upand through the hole (3)
in the leftside ofthe bobbin, from the inside.
Press down onthe bobbin andthe bobbinwinder
latch (A, Fig. 7) will dropdown and hold the bobbin
winder pulley against the hubofthe balancewheel.
Then press the treadle the same asfor sewing.

Theendofthe threadmust be held bythe hand
until a few coils are wound and shouldthen be
brokenoff. When sufficient thread has beenwound
upon the bobbin, the bobbin winder is automatically
released from the balance wheel.
FIG. 8. ADJUSTMENT OF BOBBIN WINDER
If the pressure ofthe bobbinwinderpulley against
thehubofthe balancewheel is insufficient for wind-
ing the bobbin, pressdown the bobbinwinderuntil
the latch (A) dropsdown and holds it, then loosen
the adjustingscrew (F). With the forefinger, push
back the upper endofthe slotted plate (E)asfar
asit will go,as shown in Fig. 8,andatthe same
time press the bobbin winder pulleyagainst thehub
of the balancewheel,thentighten the adjusting
screw (Fj.
If the threaddoes not windevenly on the- bobbin,
loosen the screwwhichholds the tensionbracket
(2, Fig. 7)in position onthebedofthe machine and
slide the tension bracket tothe right or left, asmay
he required,thentighten the screw.
Bobbins can also be wound while the machine
is sewing.

(SEE FIG. 14)
Turn the balance wheelovertoward you until
the threadtake-uplever (5)is raised toits highest
point. Place the spool of thread onthe spool pin
atthetopofthe machine- and pass the thread to

and from right to left between the tensiondiscs(2).
With the righthandhold the spool to prevent it
from turning, and with the left handdraw the thread
up into the take-up spring (4) until the thread
enters the retaining fork (3), then pass the thread
from right to left through the hole inthe thread
take-up lever (5), downthrough the guide (6) on
the face plate,into the wire guide (7)onthe needle
bar bushing,into the guide (8)onthe needleclamp
