CARD
SORTING
MACHINE,
TYPE
82
The cards are sorted in the normal manner
accord-
ing to the digits 1 to 9 in the first column to
be
sorted.
The
zone
contact bar on the commutator (Figure
4)
is
then moved
to
the center of the commutator and
the complete sorting operation repeated on the
same
card column. Positioning the
zone
contact bar in this
manner suspends sorting for all values of punching
except
0,
11
and 12. Those
cards
which fall in the
12
pocket will contain the letters A to I
in
alphabetic
sequence; those in the
11
pocket, the letters J
to
R;
and those in the
° pocket, the letters S to Z. Succeeding
columns are each sorted in the
same
manner
as
above;
the digits 1
to
9
first,
followed
by
sorting of the zone
punchings
0,
11
and 12. When cards
are
removed
from the pockets following a
zone
sort, the
12
zone
cards should be placed
face
down
in the card magazine,
the
11
zone
cards next; and the °
zone
cards
last in
preparation for digit sorting on the next column.
In
most
cases,
it
is
not necessary to sort on all columns
of a name field to place the cards
in alphabetic order.
Usually sorting on the first three or four characters in
a group of names will
be
sufficient.
