Having removed the bobbin from the spool winder, take it

between the thumb and finger of the right hand, being careful that

the thread is over the bobbin towards the hand. At the same time
take the shuttle in the fingers of the left with its point towards the
hand, place one end of the bobbin in the spring centre in the end of
shuttle cavity next to the point, and gently press the other end

into its place. Pass the thread through the bottom long slot, in at

the upper slot, and thence over to the tension holes, passing it
through the one nearest the blunt end first, then through as many
holes as may be necessary to obtain the tension required, always
finishing, however, by passing it through the hole nearest the point,
either from the inside outward, or from the outside inward (in the
latter case pass it out through the slot below) and finally, in every
case, under the spring.

TO COMMENCE SEWING.

Open the left hand shuttle slide (33), place the shuttle in its

carrier (57), leaving out about two inches of thread. Close the slide

to within an eighth of an inch, draw about two inches of thread
down from the check lever (15) and through the eye of the needle.

Hold the end of thread with the left hand, allowing it to be slack

from the hand to the needle, and turn the wheel (88) towards you
until the needle moves down and up again to its highest point.
Pull the thread you are holding, and the under thread will be
brought up with it through the hole in the throat plate. Close the
slide, place both ends of thread and the material to be sewn, under

the presser foot, lower the presser bar lifter (25) and commence to
sew by turning the balance wheel from the top tow'ards you. After
making a few stitches, stop and examine them. Should there be
loops projecting or a straight thread upon the lower surface, turn
the tension screw (5) on the top of the machine to the right, so as to
tighten the tension on the needle thread. If the thread lies straight
upon the upj)er surface, turn the tension screw to the left to loosen
the tension of the needle thread. The secret of perfect sewing lies
in adjusting the tension on the needle thread and that on the shuttle

thread so that they are equal.

TO THREAD THE SHUTTLE.

TO REMOVE THE WORK.

Raise the needle bar (9) to its highest point, draw about three

inches of thread downwards from the check lever (15), and raise the
lifter (25). Move the material back and to the left about three inches
and cut the threads close to the work so as to leave the ends long
enough to recommence sewing. Before removing the work from

the machine, however, seams should be secured by taking a few

stitches in the opposite direction, as in hand sewing.
