15 Olairns. (Cl. 235881.83)
This invention relates to tabulating machines adapted ,for automatically performing subtrac
operated under the control of perforated cards.
One of the objects of the invention is to pro
vide improved means for e?ecting subtraction
as well as addition in a card controlled tabulator.
Another object of the invention is to provide
improved means for preserving in the machine,
and for printing, a grand total of a series of
group totals.
10
Another object of the invention is to provide
an improved construction in which one or more
algebraic accumulating units can be mounted on
and coupled to a tabulator having a plurality of
adding units.
*5
Another object is the provision of a new rotary
shaft for operating the mechanism and its con~
trols.
Another-object of the invention is to provide
improved automatic means for effecting direct
£30 subtraction of data contained in record cards,
such means being under control of the record
cards themselves.
Another object of the invention is to provide
for the printing of grand totals automatically
"'3 under the control of the cards.
'
Another object of the invention is to provide
improved means for computing positive or nega—
tive balances, for printing the same, and- for auto
matically printing a suitable mark to indicate the
30 characteristic of the balance.
‘,
Another object of the invention is to provide
improved means for automatically transferring
group totals that have been inserted in one ac
cumulator to a second accumulator that is ar
35 ranged to accumulate grand totals. -
Another object of the invention is to provide
improved means for automatically printing
special characters to identify the type of opera
tion which resulted in the printing of certain
40 quantities such as negative items, negative totals,
positive totals, grand totals, etc.
Another object of the invention is to provide
means to accumulate a plurality of positive and
negative totals,‘ and to compute and print the
45 true grand total or net balance ofsaid totals.
Another object is to provide novel means, under
the control of record cards for predetermining
special operations of the machine. Other objects
will appear in the course of the following de
50 scription.
.
The invention is capable of considerable modi
?cation. In the particular instance shown in
the drawings, mechanism is applied more or less
in the manner of an attachment to the existing
Powers tabulator whereby the machine can be
tion under the control of suitably prepared record
cards.
The Powers tabulator usually comprises seven
units, each of which is provided with mechanism 5
arranged to accumulate and print data contained
in record cards. These units are commonly
known as accumulating units and will be so
termed hereinafter. According to the present in
vention, additional mechanism, including units to
arranged to accumulate both positive and nega
tive items, is provided to condition the tabulator
for e?ecting subtraction as well as addition, The
added mechanism also includes a new drive shaft
having on it the necessary cams, etc., for operat- 15
ing the mechanism and controlling its functions.
One or more of the additional units may be
readily attached to the machine and each may
be connected to, and arranged to operate in
conjunction with any one of the seven accumu- 20
lating units. For convenience, the additional
units will be termed algebraic accumulating units
or algebraic units. Thus, a given tabulator may
be provided with several of the usual accumu
lating units operating individually and several ac- 25
cumulating units operating in conjunction with
algebraic accumulating units. In the case of the
accumulating units that have algebraic units as-,
sociated therewith, the controls for the regular
accumulating mechanism have been modi?ed-so 30
that these units do not accumulate items, but
merely have transferred to them the group totals
that are accumulated on the associated algebraic
units. When grand totals are taken, all the
algebraic units as well as all the accumulating 35
units that are not associated with algebraic units
are rendered inactive. 'thus, the grand totals
are taken only from those accumulating units
that have algebraic units associated therewith.
The novel functions of this machine are pref- 4°
erably performed automatically under control of
special perforations in record cards. The ma
chine is so constructed that a run, or number
of groups of cards may be placed in the machine,
which will then perform the required functions.
ri‘hus at the end of each group of cards, the.
machine will automatically print the group total,
and, if this be negative, mark it suitably, while
at the end of the run the machine will automati- 50
cally print the grand total or totals.
In the drawings Fig. l is a front to rear, verti
cal sectional view through a Powers tabulator

i8 and 20. Shaft i9 is telescopic, as stated,’ in
order to‘ permit the head to be tilted when chang-=

well known in the art and is speci?cally shown
in 1a, ‘law of Fig. 2 of the patent to Powers
1,245,502. Each such unit includes .a supporting
slide bars 88} (Fig. 29) one for each unit and each
having a stud 8i projecting into the path of an.
inclined or cam surface on a block
mounted
on a rock shaft 83. In the machine as hereto==

against end-wise motion along the shaft, in the
case of each unit that is provided with the present
improvements.
20
The rock shaft 83 is operated from the shaft
The main rock shaft 48 has for each unit a
20 resiliently connected crank cam sector 56 having
pivoted thereto at St a link 52 which is pivoted
to a cam piece 53 which by follower roller 54
operates the restoring frame consisting of side
arms 55 and cross bar 56,,the last lying in con
25 tact with the type sectors 35.
The accumulator ineach unit is moved into
and out of mesh with the racks 31 by the usual
rocker cam arms or camrning hooks 5‘! (see also
Fig. 19) controlled by the pitman 58 having the
30 upper notch 60 and the lower notch 6i cooperat
ing respectively with pins 82 and '63 on an inter

(Fig. 25) connected to arms Hi3 and (1155 fixed
on the respective shafts.
According to the present invention, an alge 25
braic accumulating unit is mounted behind and
connected with any desired one of the accumulat
ing units. The operation of the algebraic unit
is controlled, in respect to the amounts inserted
in it, by the accumulating unit to which it is con 30
nected and in other respects, is automatically
mittently rocking piece 64, which is rigid with
controlled in a manner described hereinafter. In
a rock shaft 65 and controlled by‘the usual fol
lower arm 66 (Fig. 19) operated by the crank
or fan cam 50, all as well known in the art. Said
fan cam 59 is here shown ?exibly connected with
the shaft 48 through means including an arm 61
fast on the shaft and a strong spring 68 to pre
vent breakage in case the mechanism is for some
40 reason unable to operate.
The machine includes the usual total shaft ‘in
having an arm 1| (Figs. 1 and 26) connected to
and rocked by a link 12. This link is controlled
the present instance, the various functions of the
mechanism are controlled by special perfora
p. G!
for total taking purposes by‘ mechanism similar
to that shown in the Lasker Patent No. 1,376,555;
but the mechanism controlled by this shaft has
'beenmodi?ed for the purposes of the present
invention as will be hereinafter described.
The main drive shaft i (Fig. 26) has thereon
50 a cam 2 which oscillates the bell crank 3 to recip
rocate the total card controlled walking beam
4. If a total card is not present the walking beam
stud 5 fails to align with the companion stud
on the total-setting bell crank 6.’ If no card is
55 present in the machine, the stud 5 passes below
its companion, and if a card other than a total
card is present, it passes above. If a total card
is present, the studs are in alignment. Then
bell crank 3 through the walking beam and co
60 operating studs quickly rocks bell crank 6 suf
?ciently to permit latch 1 to lock it in operated
position. Said bell crank 6 draws link 72 down
wardly.
The machine also includes, for each unit, the
usual stop basket including a set of digit stops
13, each adapted to be projected upward into
the path of a lug 14 on the appropriate rack 31,
these stops 13 being operated by the wires 3|!
and restored by the usual bars 15. Zero stops 16
are mounted on the usual pivoted shutters 11,
said stops being cammed aside by'any projected
stop 13 and restored to normal position by usual
springs 18 (as best shown in Figs. 1, 20 and 22) .
In total taking operations all of the stops
75 ‘it are moved out of the paths of the lugs 14 by
tions in the cards, but they or some of them 35
may be controlled automatically from the cards
in other ways.
The Powers tabulator as ordinarily constructed
includes a heavy frame bar 85 at the rear of the
head, which bar is supported from the base plate 40
32 by two posts. In the present instance these
posts are replaced by brackets, or end frame
pieces 86, (Figs. 20 and 25) each of which is
secured to the base plate 32, and has the bar 85
secured to its upper part. These brackets ex
tend rearward and support a second frame bar
31. Between these brackets there is supported
a quantity of new mechanism which will be de
scribed.
The adding and subtracting mechanism is made
up in units which for convenience may be termed 50
“algebraic units." Each of these comprises right
and left frame plates 88 having cars 90 bent off
therefrom and secured to the bars 85 and 91 by
screws. The two frame plates 88 are secured to
55
gether by cross bars “14 and the various shaftsv
of the unit assembly, as will presently appear.
Since bars 85 and 81 are continuous members
and extend across the rear of the computing sec- -
tion, it is possible to include algebraic units in 60
any number of computing units.
Referring, for example, to Fig. 2 which shows
a section through one of the algebraic units, it
is seen that said unit comprises a set of accumu
lator wheels 9| mounted on a shaft 92 which can
be moved vertically. These are shown as twenty
toothed wheels, each wheel having a two-point
transfer or carry tripping piece 89 rigid there
with. These wheels are operated additively by a
lower rack bar 93, and subtractively by an upper 70
rack bar 93' and are moved to a neutral position
midway between these bars as shown in Fig. 2
by the actuation of link H0. The rack bars are '
prevented from moving vertically by cross bars
95, 95' and 96, 96' between which they move and 75
