           FIG. 2. FRONT VIEw OF THE MACHINE



     It is necessary to understand the stop motion
  (E) by which the balance wheel (D) 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 stitching
 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. 2) turn the
 stop motion serew (E, Fig. 2) 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 disconnected.
   Continue the motion thus begun by an alternate
 pressure of heel and toe, until a regular and easy
movement is acquired, and the balance 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 Operate the Hand Machine
     After removing the wooden cover from the ma-
 chine, turn the lever (H) back until it enters the
  socket (G) as shown, then turn the hinged finger
  (F) back between the spokes of the balance wheel.

            THE HAND DRIVING ATTACHMENT

   Raise the presser foot (B, Fig. 2) by means of the
presser bar lifter (C, Fig. 2) to prevent injury to
the foot (B, Fig. 2) and feed (A, Fig. 2).
    It is necessary to understand the stop motion
(E, Fig. 2) by which the balance wheel D, Fig. 2)

driving attachment and permitting the winding of
 bobbins without running the stitching mechanism.
  It also allows the operator to wind bobbins without
removing partially sewn work and without unthread-
 ing the machine.

To release the balance wheel (D, Fig. 2), turn
  the stop motion screw (E, Fig. 2) over toward you.
   It will be necessary to hold the balance wheel
  while loosening the stop motion screw.
    After releasing the balance wheel, turn the lever
  (H, Fig. 3) of the hand driving attachment over
  from you, continuing the motion thus begun until
  a regular and easy movement is acquired.
   When you are thoroughly familiar with the move-
 ment of the hand driving attachment, 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 with the
 left hand.
   NoTE: To release the lever (H) from the socket (G) it is nec-
  essary to first withdraw the plunger (J. Fig. 3.)

   To Insure 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 bobbin case
 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.
  The slide over the bobbin case should be kept
closed when the machine is in operation.

           To Remove the Bobbin

   Turn the balance wheel over toward you until
 the thread take-up lever (5, Fig. 12) is raised to

 its highest position. Draw to the left the slide
in the bed of the machine. Reach down with
 the thumb and forefinger of the left hand, open
 the bobbin case latch (A, Fig. 4) and lift out the
 bobbin case. While the latch remains open, the
bobbin is retained in the bobbin case.
the latch, turn the open end of the bobbin case
 downward and the bobbin will drop out.

          To Wind the Bobbin
                  (SEE Fig. 5)
   Release the balance wheel by turning the stop
 motion screw (C, Fig. 5) over toward you. It
 is necessary to hold the balance wheel (B) while
 loosening the stop motion screw.

 the small pin in the shoulder enter the hole in the
 side of the bobbin. Put the spool of thread on the
spool pin (1). Draw the thread under and between
the tension discs (2) on the bed of the machine,
then pass the thread up and through one of the holes
 (3) in the left side of the bobbin, from the inside.
 Press down on the bobbin and the bobbin winder
latch (A, Fig. 5) will drop down and hold the bobbin
 winder pulley against the hub of the balance wheel.
 Then operate the machine the same as for sewing.
  The end of the thread must be held by hand
 until a few coils are wound and should then be

10
broken off. When sufficient thread has been wound
 upon the bobbin, the bobbin winder is automatically
 released from the balance wheel.

            Fig. 6. ADJUSTMENT oF BOBBIs WINDER

    If the pressure of the bobbin winder pulley against
 the hub of the balance wheel is insufficient for wind-
 ing the bobbin, press down the bobbin winder until
 the latch (A, Fig. 6) drops down and holds it, then
 loosen the adjusting screw (D, Fig. 6). With the fore-
 finger, push back the upper end of the slotted plate
 (E) as far as it will go, as shown in Fig. 6, and
at the same time press the bobbin winder pulley
 against the hub of the balance wheel, then tighten
the adjusting screw (D).
    If the thread does not wind evenly on the bobbin,
loosen the screw which holds the tension bracket
 (2, Fig. 5) in position on the bed of the machine and
 slide the tension bracket to the right or left, as may
be required, then tighten the screw.
   Bobbins can also be wound while the machine
is sewing.

       To Thread the Bobbin Case
   Hold the bobbin
 between the thumb
and forefinger of
the right hand, with
the thread on top
 drawing from right
 to left, as shown in
Fig. 7.


                                  Fig. 7
                      With the left hand
                           hold the bobbin case as
                   shown in Fig. 7, the
                              slot in the edge being
                              at the top, and place
                       the bobbin into the
                        bobbin case.

            Upper Threading


                       (SEE FIG. 12)
  Turn the balance wheel over toward you until
 the thread take-up lever (5) is raised to its highest
 position. Place the spool of thread on the spool pin
 at the top of the machine and pass the thread to
the left through the thread guide (1) at the rear of
 the face plate, down, under and from back to front
between the tension dises (2), the thread guard L)
 guiding the thread between the dises. (See insert in
 Fig. 12). With the right hand hold the spool to
 prevent it from turning, and with the left hand
 draw the thread up into the take-up spring (4) un-
til the thread enters the retaining fork (3), then
 pass the thread up and from back to front
 through the hole in the thread take-up lever
 (5), down through the guide (6) on the face plate,
 into the guide (7) on the needle clamp and from
 right to left through the eve (8) of the needle.

  Draw about two inches of thread through the eye
 of the needle with which to commence sewing.

16

              To Prepare for Sewing

   With the left hand hold the end of the thread,

  leaving it slack from the hand to the needle. Turn





                           £9736

         Fig. 13. DRAWING Up THE BOBBIN THREAD

  the balance wheel over toward you until the needle
 moves down and up again to its highest position,
 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, as shown
in Fig. 13. 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, turn-
ing the balance wheel over toward you.

17



           To Remove the Work
   Stop the machine with the thread take-up lever
  (5, Fig. 12) at its highest position, raise the presser
 foot and draw the fabric back and to the left, pass
 the threads over the thread cutter (A, Fig. 13) and
 pull down lightly to sever them. Leave the ends of
 the threads under the presser foot.

          To Turn a Corner

   Stop the machine when the needle is commencing
 its upward stroke. Raise the presser foot and turn
 the work as desired, using the needle as a pivot,
 then lower the presser foot

   To Regulate the Pressure on the Material

  For ordinary family sewing, it is seldom necessary
 to change the pressure on the material. If sewing
 fine silk or flimsy material, lighten the pressure by
 turning the thumb screw (A, Fig. 25) on the top of
 the machine over to the left so that it screws up. To
increase the pressure, turn this thumb screw over to
 the right so that it serews down. The pressure
 should be only heavy enough to prevent the material
 from rising with the needle and to enable the feed to
 move the work along evenly. The heavier the ma-
 terial, the heavier the pressure; the lighter the
material, the lighter the pressure.

18
      To Regulate the Direction of Feed
  To feed the goods from you, push down the
 stitch regulator lever (B, Fig. 14) as far as it will go.





                          5081

    FIG. 14. SHOWING LEVER FOR REVERSING DIRECTION
        OF FEED AND REGULATINg LENGTH OF STITCH


  To feed the goods toward you, raise the stitch

 regulator lever (B) as high as it will go.
  The direction of feed can be reversed at any point
 of a seam without removing the work from the
machine.
  Back tacking is therefore readily accomplished
 and the fastening of the ends of seans is made easy.

19

       To Regulate the Length of Stitch

   The machine can be adjusted to make from 6 to
 30 stitches to the inch as indicated by the numerals
 on the stitch indicator plate (C, Fig. 14).
   The number of stitches to the inch that the ma-
chine is set to make is indicated by the number which
  is in line with the upper side of the stitch regulating
lever (B, Fig. 14).
  To change the length of stitch, loosen the thumb
 screw (A, Fig. 14) and move it to the bottom of the
  slot. Then move the stitch regulating lever (B) until
 its upper side is in line with the number of the de-
 sired length of stitch. Now move the thumb screw
 (A) until the stitch regulating plate touches the
 lever (B), then tighten the thumb serew (A)
   The machine will now make the indicated number
 of stitches to the inch in either a forward or reverse
 direction, depending on whether the lever (B) is at
 its lowest or highest position.


                Basting
  The longest stitch made by the machine, No. 6
on the stitch indicator, is found satisfactory for
 basting, after loosening the tension on the needle
thread so that the stitches may be easily pulled
from the material.
  Machine basting is firmer and more even than
that done by hand in addition to being much quicker.

      To Sew Flannel or Bias Seams
  Use a short stitch and as light a tension as possible
 on the needle thread so as to leave the thread loose
enough in the seam to allow the goods to stretch
 it necessary.
