Instructions for Operating the Machines

Raise the presser foot (B, Fig. 3) by means of

the presser bar lifter (C, Fig 3) to prevent

injury to the foot (B, Fig. 3) and feed (A, Fig.

3).

FIG 3. FRONT VIEW OF THE MACHINE

It is necessary to understand the stop motion

(E, Fig. 3) by which the balance wheel (D,

Fig. 3) can be released when required, thus

enabling the operator to become proficient in

the use of the treadle and permitting the

winding of bobbins without running the stitch-

ing mechanism. It also allows the operator to

wind bobbins without removing partially sewn

work and without unthreading the machine.

To release the balance wheel (D, Fig. 3), turn

the stop motion screw (E, Fig. 3) over toward

you. It will be necessary to hold the balance

wheel while loosening the stop motion screw.

After releasing the balance wheel, place your

feet upon the treadle and with the right hand

turn the balance wheel over toward you. This

will start the band wheel, treadle and pitman,

the sewing mechanism having been discon-

nected.

Continue the motion thus begun by an alter-

nate pressure of heel and toe, until a regular

and easy movement is acquired, and the bal-

ance wheel kept in continuous rotation by use

of the feet alone.

When you are thoroughly familiar with the

treadle movement and can restart the

machine without turning the balance wheel in

the wrong direction, tighten the stop motion

screw to connect the balance wheel with the

stitching mechanism.

Place a piece of cloth under the presser foot,

let the foot down upon it, and operate the

machine in this way without being threaded,

until you have become accustomed to guiding

the material.

To Ensure Perfect Action of the Machine

The balance wheel must always turn over

toward the operator.

Do not run the machine with the presser foot

resting on the feed without cloth under the

presser foot.

Do not run the machine when both shuttle

and needle are threaded unless there is

material under the presser foot.

Do not try to help the machine by pulling the

fabric lest you bend the needle. The machine

feeds the work without assistance.

Both slides over the shuttle should be kept

closed when the machine is in operation.

To Remove the Shuttle

Draw toward you the front slide in the bed of

the machine and turn the balance wheel over

toward you until the shuttle comes full under

the opening. Press the forefinger of the right

hand upon the shuttle ejector as shown in

Fig. 4, this will raise the shuttle so that it can

be easily taken out. Turn the open end of the

shuttle downward and the bobbin will drop

out.

To Wind the Bobbin

Release the balance wheel (D, Fig. 3) by

turning the stop motion screw (E, Fig. 3) over

toward you.

Draw to the left the knob (A, Fig. 6, page 7)

and place the bobbin between the cups (B

and C, Fig. 6), then release the knob. Push

the bobbin winder pulley (D, Fig. 6) against

the hub of the balance wheel, and turn the

balance wheel until the thread guide (4, Fig.

6) moves to the extreme right. Put the spool

of thread on the spool pin (1, Fig. 5). Pass

the end of the thread into the thread guide (2,

Fig. 5) at the top of the face plate, then up

into the lower eyelet (3, Fig. 6) of the bobbin

winder thread guide, into the notch (4, Fig. 6).

With the thumb and forefinger of the left hand

press the bobbin lightly to the left and place

the end of the thread between the bobbin and

the cup (C, Fig. 6) at the right. Then operate

the machine the same as for sewing. When

the bobbin is filled, remove it from the bobbin

winder, pull the bobbin winder away from the

hub of the balance wheel and turn the stop

motion screw over from you to connect the

stitching mechanism.

To Thread the Shuttle

Hold the shuttle between the thumb and fin-

gers of the left hand as shown in Fig. 7.

Place the bobbin into the shuttle with the

thread drawing toward the right from the side

of the bobbin nearest you, as shown in Fig. 7.

Place the forefinger of the left hand on the

end of the bobbin and draw the thread down-

ward into the long slot in the shuttle as far as

it will go, as shown in Fig. 8.

Then draw the thread straight upward and

under the tension spring as shown in Fig. 9,

until the bobbin begins to unwind. FIG. 7

To Replace the Shuttle

After threading, take the shuttle in the right

hand with the point toward you and the ten-

sion adjusting screw (1, Fig. 7, page 8)

upwards. Put the point of the shuttle into the

front end of the shuttle carrier as shown in

Fig. 10, and drop the shuttle into place, leav-

ing a loose end of thread about three inches

long above the slide. When closing the slide,

leave just enough space for the thread to

pass through.

FIG. 10. REPLACING THE SHUTTLE

To Set the Needle

Turn the balance wheel over toward you until

the needle bar (E, Fig. 5) moves up to its

highest point, loosen the thumb screw (C,

Fig. 5) in the needle clamp (B, Fig. 5) and put

the needle up into the clamp as far as it will

go, with its flat side toward the right, then

tighten the thumb screw. To select the correct

needle. ??REFERENCE??

FIG. 11. THREADING THE NEEDLE

To Thread the Needle

SEE FIG. 11

Turn the balance wheel over toward you until

the thread take-up lever (4) is raised to its

highest point. Place the spool of thread on

the spool pin at the top of the machine, lead

the thread into the thread guide (1) at the top

of the face plate, down under and from right

to left between the tension discs (2), into the

small wire spring (3) at the left of the tension

discs, up and from front to back through the

hole in the end of the thread take-up lever

(4), down into the eyelet (5) in front of the

face plate, into the lower wire guide (6) then

from left to right through the eye of the nee-

dle (7).

Draw about two inches of thread through the

eye of the needle with which to commence

sewing.

To Prepare for Sewing

With the left hand hold the end of the needle

thread, leaving it slack from the hand to the

needle. Turn the balance wheel over 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. 12) Lay

both threads back under the presser foot and

close the slides.

FIG. 12. DRAWING UP THE BOBBIN THREAD

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.

Remove the Work

Let the thread take-up lever rest at its highest

point, raise the presser foot and draw the fab-

ric back and to the left, pass the threads over

the thread cutter (A, Fig. 12) and pull down

lightly to sever them. Leave the ends of the

threads under the presser foot.
