THREAD
CONTROLLER
See
Fig.

The
function of
the
thread
controller
spring
is to hold
back
the slack of the upper threads until the eyes of the needles reach
the goods in
their
descent.
For
a longer action of the double thread controllers, loosen
screw (B) and set stop (C) lower. For less action of the thread
controllers, reverse
the
operation.
To strengthen the action of the inside thread controller (D),
loosen screw
(E)
and
turn
nut
(F)
to
the
right and tighten
the
screw.
To strengthen the action of the outside thread controller
(G), loosen the set screw in thumb nut
(H)
and turn thumb nut
(H) to the right, then tighten the set screw. For lighter action
reverse
the
operations.
TO
CHANGE
THE
LENGTH
OF
STITCH
The
clamp screw (nn, see Fig. 2) is tightened so that an
operator cannot change the number of stitches to the inch for
which
the
machine is
set;
but
if a change of
stitch
is desired,
loosen screw (nn) and tighten it after moving handle (pp) for
the desired length of stitch. If handle (pp) moves too easily,
tighten the screw at the left of and closeto the handle.
