of 280 to 400 grams applied to the 2 or 8 selector
magnet armature (at a point just under armature
backstop) should hold the armature fully attracted.
A force of 110 to 230 grams should be required to
hold select magnet 1 or magnet 4 armatures fully
attracted.
6. With a chute blade removed and held on a flat
surface, the tab containing the chute blade mounting
screw hole should project 1/8"± 1/64" above the
flat surface.
TRANSPORT ROLL ADJUSTMENTS
1. The lower pressure rolls should be centered
directly below the upper rolls. This can be accomp-
lished by inserting a .010" feeler gage leaf between
the upper and lower rolls and adjusting the lower roll
mounting brackets until the feeler gage leaf is parallel
to the card line.
'2. Tension on the pressure rolls is adjusted by
the lower feed roll shaft mounting screws so that pull
of 1.5 1b to 2.5 1b is required to pull a card strip
from between the rolls (upper roll not turning).
Tension on the front and rear rolls should be within
1/4 1b of each other. The card must be pulled in the
same direction as it is fed. After adjusting, be sure
locknuts on the mounting screws are tight.
NOTE: Push-pull scale, PiN 9900012, may be used.

JAM BAR ADJUSTMENTS
1. A jam bar must be positioned for .020" to
.035" clearance between the formed points and the
shear plates over the entire length of the card trans-
port and at the junction of the jam bar and jam bar
lever (Figure 3-4).
2. The tape must be adjusted so that the switch
will be operated with a tape deflectionofl/16".
STACKERS
Principles of Operation (Figure 3-5)
The stackers used on the 1402 are the radial type.
The stacker receives the card from the transport
mechanism with the card horizontal. The distance
from the top of the guide assembly to the lip of the
pivot and lever assembly is less than the length of
the card.
As a result. the front of the card is held
by the card restraining lever. and the rear of the card
falls, guided by the guide assembly. The radius of
the guide assembly is such that as the rear of the card
approaches the bottom. the front falls from the card
restraining lever that has been supporting it.
The card stops with the back edge on the card
alignment lever and the front edge on the card deck
support or card previously stacked. Spring tension
supports the card alignment lever until 4 to 6 cards
accumulate.
Their weight overcomes the spring
tension supporting the card alignment lever, and
lowers the group of cards into the card pusher slide.
The pusher slide oscillating front to back works the
bottom of
the
card deck support. This can continue
until the card deck support moves out enough to oper-
ate the stacker stop microswitch operating arm,
which stops the machine.
The card jogg1er mech-
anism is driven from either or both the punch and
read feeds.
The N/R and 1 stacker jogg1ers are operated by
the read feed and the N/P and 4 stacker jogg1ers are
operated by the punch feed. The 8/2 stacker jogg1er
is connected to both the read and punch feeds by
means of two helical springs and collars so that it
can be operated
by
either feed.
The card levers on the pivot and lever assembly
keep the cards from going back into the stacker where
they might jam the machine.
