CARD
SORTING
MACHINE,
TYPE
75
other counters are reset. The reset of the grand total
counter is selected by
~he
operator under control of an
additional operating lever.
A standard Type 80 Sorter is used in the construc-
tion of the Type 75 machine and all of the Type 80
sorting features have been retained. The mechanical
principles, removal procedures, and adjustments of the
sorting mechanism on the Type 75 machine are the
same as those on the Type 80 machine.
Speed and Capacity
The speed of the Type 75 Sorter is 400 cards per
minute for Model 1 and 250 cards per minute for
Model 2.
The capacity of the card magazine is 550 cards. The
capacity of each of the fifteen counters used is 99999.
OPERATING FEATURES
WITH THE exception of those items pertaining to the
operation of the card counters, the operating features
of the Type 75 machine are the same as those for the
Type 80.
Switches (Figure 29)
Three switches marked
SOrt,
card count, and total
card count are located on the front of the machine be-
low the card magazine. When the sort and card count
switches are on, counting takes place in all counters
and all cards are sorted according to the punching in
the column passing under the card brush. When only
the sort switch is on, sorting takes place but counting
does not. When only the count switch is on, counting
takes place in all counters but the cards are passed to
the reject pocket.
When the total card count switch is in the off posi-
tion, the grand total counter will not count unless the
card count switch is on. When the total card count
switch is on, it permits counting in the grand total
counter regardless of the setting of the count switch.
Thus, with the card count switch off, and the total card
count switch on, the grand total counter will count all
cards passing through the machine but no other coun-
ters will operate.
Counter Reset (Figure 29)
A reset handle is located on the right end of the
counting unit assembly. This handle is held in the zero
position by means of a detent mechanism. To clear the
counters, the reset lever must be pushed to the rear
and the reset handle rotated one full turn clockwise
until the detent reseats to hold the reset handle in its
zero position. When only the reset lever is engaged,
the grand total counter will not clear during a reset
operation. To clear the grand total counter, the grand
total reset clutch lever must also be pushed to the rear.
It is possible to clear all counters except the grand total
counter during a reset operation but it is not possible
to clear the grand total counter without clearing the
rest of the counters also.
When counters are being cleared, all machine cir-
cuits are broken by the opening of the reset interlock
contact.

MECHANICAL AND ELECTRICAL PRINCIPLES
THE MECHANICAL and electrical sorting principles of
the Type 75 Card Counting Sorter are identical to those
of the Type 80 machine. The mechanical and electri-
cal principles of card counting are explained below.
Card Counters
The
type
of card counter assembly used in the count-
ing unit of the Type 75 sorter is shown in Figure 30.
Fifteen such counters are
e~ployed
in the machine.
They are numbered according to the number plates on
the counting unit cover.
