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.
