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.
