the rate at which the ratchet wheel IOI is ro

It is apparent that the pin wheel operating
structure shown in Figure 'I'may be used either
with or without mechanism for providing an
eject operation. If an eject operation is desired,
suitable and well known mechanism may be pro
vided for rotating the sprocket shaft I‘! in timed
relation with the rotation of the star wheel I02.
A suitable inertia device for preventing re

is turned above a predetermined minimum an

switch 85 and the wheel I05. A pin I09 is sus
