NON-

JAMMIHG

FEATURE

Fig- ITi

One of the outstanding engineering inno-

vations incorporated in this machine eliminates,

for all practical purposes, the age old problem

of jamming.

Other round bobbin, oscillating machines tend

to jam, or freeze, when thread is impropetly

introduced

into

the

race

assembly.

This

nitroduction of alien thread is usually the

result of sewing without material tn the ma

chine or of turning the balance wheel back

wards while the machine is threaded.

Should this happen while you are using your

machine, the thread will simply break and,

by the action of a scientifically cut hook.

the thread will be swept out of the race and

the machine freed almost instantly. The ma

chine may seem to become stiff for a

moment. Do not be afraid to free the ma

chine by turning the balance wheel TOWARD

YOU by hand.

Your dealer will be happy to show you the

operation of the precision engineered single

screw race assembly and to explain the action

of the cut hook in preventing jamming.
