Accumulating mechanism
The adding mechanism is entirely similar to
that shown and described in the application re
IQ Ll ferred to and the description thereof will accord
ingly be limited to a brief explanation of its
manner of operation. The accumulator drive
shaft 53 (Fig. 6) is geared directly to- the pulley
Read-out mechanism
Also driven by gear ti (Fig. 6) is a gear 65.
Since the ratio of gears 65 and 62 is 2:1. the
former will turn through a halfvrevo-lution for
each revolution of the latter. Carried by and
insulated from gear 65 is a pair of electrically
connected brushes '65, one of which cooperates
successively with ten conducting segments 61
while the other cooperates with an arcuate con~
ducting strip 63.
ri‘he relationship of the partsis such that when
the index wheel 63 is inits zero position, one of
the brushes G6 is in contact with the zero seg
ment Eli and the other brush is in contact with
the strip 5%, thus forming an electrical connec
tion between the two. If the wheel 63 is dis 20
placed to indicate, say “8”, then ‘one of the
will be‘ in contact with the “8”, seg
ment 51"’ and the other brush will be in contact
with the arcuate strip

clutching member 54 into engagementwith co-_
operating teeth 60 integral with a gear 60 loosely
mounted on shaft 53. Gear 5i, when thus cou
pled to shaft 53, will rotate a gear
meshes therewithand will displace the accumu
lator index wheel 53. '
The rearward extremity of member 55 is adapt
ed to be engaged by a ?nger til toward the end
of the cycle for the purpose of disengaging the
clutch element 54 from teeth 50 and re-latching
block-58 on armature 5i.
Brie?y summarizing the adding operation, the‘
magnet 58 may be energized at various points in
the cycle of the machine, depending upon the
location of a perforation in the column of a rec
ord card analyzed by the lower brushes LB.
Accumulator resetting mechanism
The shaft
(Fig. d).upon' which the index
wheels 63 of an accumulator are loosely mounted
is slotted for cooperation with spring-pressed

the individual index wheels in such manner that
counterclockwise rotation of shaft 55 will engage
and drive the index wheels 53 forwardly to zero
position during a single revolution of shaft @9 40

in ACC#2 which will receive all totals and at the
completion of all tabulating operations will show
what is termed the “route” total which may be 60
compared with a known value. After all the
record cards for a particular “route" have been
analyzed the machine will stop.

the minor group classi?cation perforations which

During the total taking cycle when cam con

Relay magnet R38 opens its contacts 38a which
are in the main clutch'magnet circuit at_ the up

relating to merchandise placed at the end of the

such analysis is suspended until transferring has
been e?ected will be explained hereinafter.
Record cards bearing data relating to mer
chandise have an “X” punching in column 54 and
the upper brush traversing this column is con

machine opens to break the above traced holding
circuit which extends through stop key contacts

Tax transfer cycle.—The machine is now pre
pared to transfer the tax amount from ACC#4
to ACC#I. This transferring is aigain controlled
through the type bar contacts; that is, the data
is read from the accumulator and entered upon
65 the type bars, which, if properly set for duplicate
printing, will effect the entry in ACC#I.
Referring now to Fig. 8b the amount standing
in AC_C#4 will be represented by the location of

upon one or more card feeding cycles during
which the merchanidse amount will be printed
and entered into ACC#|. Resumption of card
feeding is brought about as follows:
10 When both relay magnets R99 and RI00 are
deenergized their related contacts R99g and
Rl00g will be closed and the circuit through re
lay magnet R39 re-established so that in turn
contacts R39b will be closed to energize the card
15 feed clutch magnet I8 and the merchandise card
will proceed past the lower brushes which will
complete the printing and entering circuits in the
same manner as explained in connection with
the entry of data from the gross and net bill
20 fields. It is in these same ?elds that the mer
chandise amount is perforated.
Total printing and reset cycle
The circuit through relay magnet R39 includes
25 the minor control relay magnet contacts R430 and
R43d which upon detection of a group number
change by the automatic group control mechanism
GC will interrupt further card feeding and auto
matically initiate total taking and resetting op
30 erations. Opening of contacts R43c will inter
rupt card feeding in thenow familiar manner
and closure of contacts R43d will complete a cir
cuit from line III, wire II2, contacts P9, R99g,
Ri00g, R43d, cam contacts LI9, relay magnets
30 R40 and R49 to line H3. The contacts R40a of
relay magnet R40 are in the reset magnet circuit
and upon closure will cause energization of this;

mechanism controlled by magnet 8|, theshaft

place will be printing of the total standing in
will continue to accumulate to obtain a grand
total of all the entries transferred from ACC#I.
Automatic resumption ‘of card feeding
Cam contacts L3 (Fig. 8) are provided to en
ergize the start relay magnets R32 and R33 near
the end of the resetting cycle of operations to
pick up and energize the card feed clutch magnet
I8. The circuits involved in the starting of the
machine have already been traced in detail and 10
the operations controlled thereby will proceed in
the same manner as explained above.
If it is'desired to have the machine stop after
the completion of the resetting operation, switch
I30 (Fig. 8) is initially set in its dotted line posi
tion and near the end of the resetting cycle cam
.contacts P5 close momentarily to complete a cir
cuit through the relay magnets R31 and R39, the
former of which provides a holding circuit
through contacts R3‘Ia and cam contacts L4.
The relay magnet R38 opens its contacts R30a
in the upper part of Fig. 8 to prevent the re
establishment of the starting circuit and the
machine will Xconsequently come to rest at the
completion of the resetting cycle of operations 25
and resumption of operations may then proceed
through initiation of the start key to close con
tacts H9. As explained above, the failure of
the type bars to record identical information in
the several portions of the bill will e?ect ener

the machine to stop at the completion of reset

In this manner, the entry in ACC#I is printed

cycle, the resetting instrumentalities will come
into play to zeroize the several accumulators in
the manner explained above. In connection with

Relay magnet R4I opens its contacts R4Ia
in the starting circuit, preventing the completion
of the same.
The machine will come to rest
with lamp I48 illuminated. It will thus be ap
parent that the machine will automatically come
to a stop under two conditions. First, when
there has been a discrepancy in printing, and
second, when there has been a major group
change. In order to indicate under which of
these conditions the machine has come to rest,
the lamps I29 and I48 are provided, for former

is due to a. printing discrepancy, and the latter, 70
that the cards relating to a particular route have
