A further feature of the present invention re
sides in the provision of a construction wherein
groups of- detail cards may be usedeach group

called summary card with a special characteris

machine. Suchrecords can then be tabulated
in any desired manner.
J
One use of a machine of this class would be
for effecting computations wherein net pro?ts and
costs are to be computed. In such computations
the A term or component of a problem would be
the gross selling price of a number of units. The
B term might represent the number of units sold
and the C term the cost price per unit. The
?nal result of the computation A—(B><C) would
be the pro?t on the transaction and the inter
mediate result or 8x0 would be the‘ cost of the
units sold.
In certain previous machines, provision is made
for obtaining and setting up a summary of prod
uct“ results. Such summary of products com
prised a summation of the products obtained from
each of a series‘ of records. Heretoiore, the sum

2,106,477 ,
shaft I08 also drives the cams of a PC group of
cam contacts.
Such cams are correspondingly
designated on Fig. 3 as PC—-I through 3 inclusive.
Also driven from shaft I80 are four emitters I20,
I2I, I22 and I23. The machine is also provided
with another series of emitters which are of con
ventional construction and which are driven from
the main counter drive shaft 56 (see Fig. 1).
Five of such emitters are provided which are
10 designated I24, I25, I26, I21 and I28.
An im~
pulse distributor I29 is also provided which is
driven in unison with the cam contacts CC-I
to 5.
Reset controlled contacts
Referring to Fig. 1, the reset gear of the LH
accumulator is shown as provided with cams
adapted upon the reset of this accumulator to
cause closure of contacts I66 and I6'I._ Similar
reset contacts are shown on the SP—I accumula
tor, these being designated I68. Such I68 con
tacts, however, are normally closed contacts and
are arranged to open up upon the reset ofthe
SP—-I accumulator and to reclose at the end of
15
the resetting operation.
The foregoing description has described the
manner in which cards are drawn in succession
from the supply magazine and the manner in
‘ which the cards are carried past the various sens
ing brushes and delivered into the punching sec
tion of the machine. With the traverse of each
card past the sensing brushes 84, the various
amounts are read from the card and entered into
the receiving devices of the machine. In the
present invention the advance reading brushes 83
35 and the advanced control brush 85 are not used.
These are used with other computations and
here shown only for uniformity of illustration.
The receiving device and accumulators are of
the usual type as customarily used in tabulating
machines and are provided with electromagneti
cally actuated clutches. The various accumula
tors and receiving devices have commutator type
readout devices which will now be described.
Referring now to Figs. 6 and 7, I30 is a clutch
gear pertaining to the units order of the MP
(multiplier) receiving device. Gear I3I is driven
from this clutch gear and this gear in turndrives

current supply segment I34. There is another
brush assemblage I35U driven by‘ gear I3I which
brush traverses a segment generally designated
I36 and which segment is provided with a single
conducting spot at the zero position. The brush
I35U also traverses a common supply segment
I31. There is a similar brush I35T which is po
sitioned from the tens order clutch wheel I38 and
which also traverses the segment I36 which con
tains only the single conducting spot at the zero
position. Brush I35T also traverses a separate
common current supply segment I39. Similarly
there is a brush I32T driven in unison with brush
I 35T which traverses the segment spots I40 and
which receives current from the common current
supply segment I4I. This arrangement of brushes
and segments is repeated for higher orders in the
MP readout device, i. e. each alternate segment
is’ like I36 with only a single spot in the zero
position on each segment. Alternating with these
segments are other segments similar to I33 and
I40'with a multiplicity of spots on each segment.
The detail construction of this readout with its
brush assemblages is shown in the cross-sectional
75 view Fig. 7. The wiring of the readout will be
more fully set forth in connection with the circuit
diagram (see Fig. 13a).
MC and NG readouts
Referring now to Figs. 8 and 9, in Fig. 8 is
shown the brush driving arrangement for the
MC and NG readouts. In this embodiment the
units clutch gear train I42 drives a units brush
assemblage I43U which cooperates with a set of
segments I44 which receive current from a com 10
mon conductor segment I45. Similarly units
driving train I42 drives a brush assemblage I48U
receiving current from a conductor segment I 41
and cooperating with segments I48. Also coop
erating with segments I48 is another brush as 15
semblage I 46T receiving current from a conduc
tor. segment I49, which brush assemblage coop
erates with the segments I48 and which brush is
driven by the tens order clutch train I5_I. This
arrangement is repeated for relatively higher
orders.
RH, SP—1 and SP-2 readouts
Fig. 10_show_s the general arrangement of the
readouts for the RH accumulator, the SP--I ac
cumulator and the SP-Z accumulator. With a
readout mechanism of this sort, it will be noted
that the segment spots I52 are common to two
sets of brush assemblages designated I53 and I54
respectively and which brushes cooperate respec- -
tively with conducting segments I55 and I55.
Brush I53 as shown in Fig. 10 is driven from'the
units order clutch gear train I51. _ Brush I54 on
the other hand is ‘driven from the tens order
clutch train I58 by the gearing diagrammatically '
I illustrated.
A‘similar arrangement of brushes and readout
spots is provided for the relatively higher orders
of these accumulators and the wiring of these
readouts is shown on the circuit diagram (see 40
Figs. 13c and 13e) . Fig. 11 shows the details of
construction.
LH and I VL readouts
Referring now to Fig. 12, and Fig. 120, this
readout which is here shown and whichv is used
for the left hand accumulator, comprises a lower
section which is substantially identical in con
struction to the MCRO readout previously_de
scribed. The readout is, however, provided with
a concurrently driven upper section of somewhat
different construction and diiierently wired. The.
brush parts of the upper section are driven by
intermediategears I59, one of which is provided a
for each denominational order.
The upper sec-
‘ :
tion is substantially of. the form of readout used
vfor an inverting accumulator wherein readings
are to be taken from an accumulator which’ are -
complements of‘ the amounts standing thereon.
Such upper section will be accordingly designated CI)
IVLRO. The lower section from which real num
ber amounts are read out is designated LHRO.
The construction of the upper section will now
be described. The intermediate gear I59, pertain
ing to the units order, through gear I60 drives
brush I6IU which traverses the units segment
spots I62U and a supply segment I63U. The tens
intermediate gear I59 drives a brush assemblage
IS IT through the intermediate gear I60T. Brush
assemblage I6 IT traverses the tens order segment
spots I MT and a supply segment I63T. Segment
spots I62U and I62T are diagonally transversely
wired as shown. The relation of wires is such that
the nine spot of the I62 U group is wired to the
eight spot of the I62T group and so on. The com 75
