until a few coils are wound and should then be
broken off. When sufficient thread has been wound
upon the bobbin, the bobbin winder is automatically

the hub of the balance wheel is insufficient for wind-

the latch (A) drops down and holds it, then loosen
the adjusting screw (F). With the forefinger, push
back the upper end of the slotted plate (E) as far
as it will go, as shown in Fig. 8, and at the same
time press the bobbin winder pulley against the hub
of the balance wheel, then tighten the adjusting
screw (Fj.
If the thread does not wind evenly on the- bobbin,
loosen the screw which holds the tension bracket
(2, Fig. 7) in position on the bed of the machine and
slide the tension bracket to the right or left, as may
he required, then tighten the screw.
Bobbins can also be wound while the machine
