~ THREAD CONTROLLER
I
0
The function of th e thread controller
spring is to hold back the slack of the
needle thread until point of needle reach-
es the goods in its descent, as without
this controlling action of the spring, the
slack thread {especially silk) will some-
times be penetrated by point of needle as
needle is descending.
Fig. 22. Adjustment of Thread Controller
To change the thread controller stop
for more controller action on the thread,
loosen set screw Z, and turn thread con-
troller spring stop T, Fig. 22 to the
right; for less action, turn thread con-
troller spring stop T to the left, after
which securely tighten set screw Z.
It may be found advisable to increase
tension of spring for coarse thread, or
to lessen it for fine thread.
To increase tension of thread controller
on thread, loosen tension stud set screw
Y, located nearly under tension stud, and
turn tension stud A2 slightly to the left.
To decrease tension turn it to the right.
Re-tighten stud set screw Y 0
TO SET NEEDLE BAR
See that needle is up in the holder as
far as it will go. There are two lines
across the needle bar about two inches
above the lower end. When needle bar
is at its lowest position, the upper mark
should be just visible at end of needle
bar frame.
In case needle bar is not correctly set,
loosen needle bar connecting stud pinch
screw M, Fig. 23 and place needle bar
in correct position as directed above,
then re-tighten screw M.

TO SET A NEEDLE BAR WHICH HAS NO
MARK

on pag e 6, so that there is no fe e ding mo-
tion, then set needle bar so that when it
rises 3/32 inch from its lowest position
and point of sewing hook is at center of
needle, eye of needle will be about 1/16
inch below point of hook.
RELATIVE POSITIONS OF NEEDLE BAR
AND PRESSER BAR
The distance between the needle bar and
presser bar {after regulating stitch length
so that there is no feed movement) should
be 17/32 inch as shown below 0

Ba.r and Presser Ba.r
If the distance between needle bar and
presser bar is more or less than 17/32
inch, loosen needle bar frame shaft clamp

loose, needle bar frame can be moved for-
ward or backward, as may be required,
