Transaction keys
The machine of the present invention has four
‘totalizer lines, three lines of interspersed. to
talizers I38, I39, and I40 (Figs. 5 and 11.), and
an add-subtract or balance totalizer “I. The
totalizer lines I38 and I39 each have nine sets
of totalizer wheels, which are actuated by the
differential actuators I24. ~The actuators I24
have three sets of teeth, one set for each of the
. totalizers I38 and I39 and a set for the add
subtract totalizer MI. The lines 838 and E39
are shiftable laterally‘ in order that the desired
10 set of totalizer wheels may be alined with the
di?erentialaotuators I24. A row of keys M2
(Figs. 1 and 15) controls the selection of the
totalizers on line I38 and a row of keys 943
controls the selection of the totalizer on line 639.
15 The mechanism which shifts the totalizers iat
erally is old in the art and therefore will not be
explained, but reference may be had to Patent
No. 1,394,256 issued October 18, 1921, to F. L.
Fuller for a detailed description of this mecha
20' nism.
The add-subtract or balance totalizer “I has
two sets of wheels, a positive set and a negative
set. The keys I 42, in addition to selecting the
totalizers on line I38, also select the positive side
25 of the add-subtract totalizer for engagement with
the di?erential actuators, and the keys I43 like
wise select the negative side of the balance to
talizer for engagement with the differentials.
In'add operations, after the segments I28 have
30 reached the end of their movement clockwise,
‘ thereby setting the differential actuators H24
commensurate with the amount keys depressed,
the selected set of totalizer wheels on one of the
lines I38 or I39 (Fig. 5) and the proper side of
35 the add-subtract totalizer are moved into engage
ment with the teeth on the differential actuators
I24. The segments I28Ithen start their return
movements, picking up all the differential actu
ators I24 and returning them to their home po
40 sitions. This rotates the wheels of the selected
totalizer commensurate with the amount set up
on the keyboard. The‘ totalizers are then disen=
gaged from the differential actuators I24. Thev
differential actuators
I24 have incorporated
45 therein the usual transferring mechanisms for
adding one to the next higher order wheel when
the lower order wheel passes from 9 to zero.
These transfer mechanisms are old and will not
be further explained here, as reference may be
had to the patents referred to hereinbefore for a
complete description thereof.
Printer actuating mechanism
Calling attention to Fig. 5, pivoted on each
55 differential actuator I24 is a beam I44 bifurcated
to embrace a stud I45 in a link I46. The link
I46 exends between a toothed segment I41 loose
ly mounted on a shaft I48 pivoted between the
main frames of the'machine and an arm of a
60 gear segment I49 loose on a shaft I150. The seg
ment I49 cooperates with a gear I6I secured on a
shaft I62, which cooperates with the well known
printer rack mechanism to position the printer
engages one of the tooth spaces therein to assist _
in alining the printing mechanism.
Cycle control mechanism
Calling attention to Fig. 3, in add operations
the shaft I 06 makes one revolution to operate the
differential mechanism through one cycle of
movement. In read and reset operations it is
necessary that the di?erential mechanism op
erate through two cycles of movement. There 10
fore, it is necessary to rotate the shaft I06 two
complete revolutions in such operations. This
is accomplished by means of cycle‘control mech
anism which controls the disengaging of the mo
tors clutch in a manner now to be described. _
Journaled between the main frames I04 and
I01 is a key lock shaft I61 having secured on its
right end an arm I68 carrying a stud I66 em
braced by a slot in the upper end of a link I10
bifurcated on its lower end to receive a stud in a
pitman i'li slotted to embrace the stud I03. The
lower end of the pitman I1I is pivotally connected
to an arm i112 journaied on a stud I13 carried by
the frame tilt. The arm I12 has an extension I16
connected by a link 915 to an arm I16 secured on
a zero latch throwout shaft I11 (see also Fig. 9)
extending through the machine and journaled in
the main frames GM and I01.
The link tilt has a stepped opening I18 which
cooperates with a stud 819 in a cam arm I80 30
pivoted _on the stud its (Fig. 3). The arm 880
carries a roller E86 which cooperates with a cam
‘race B82 in the gear B62. The race N32 has di
ametrically opposed cam sections which cooperate
with the roller Wit near the end of each cycle 35
of movement to rock the arm I80 ?rst clockwise,
then back to normal position. Retained in
in the link 318 by means of a projection is a
spring Q83 operatively connected to the arm 568,
which spring is compressed to urge the shaft 861 40
In Fig. 3 the cycle control mechanism is shown
in its normal or adding position. Releasing the
machine for an add operation by depressing the
motor bar I08 frees the shaft E61 to the action
of the spring I83, which forces the shaft clock
wise until the arm I68 strikes a stop stud H86
secured in the frame I04. This movement of the
shaft I61 engages the motor clutch and locks the
amount' keys in the well known manner.
As previously explained, the shaft “it makes
one revolution clockwise in add operations and
the gear I02 makes one-half revolution counter
clockwise. Just as the gear I02 is completing
its movement, the arm I80 is rocked clockwise 55
and back, as previously explained, and
stud I18 at this time engages the top step in the
opening I18, the link I10 receives its maximum
downward movement. This declutches the motor
from the driving mechanism and releases the de 60
pressed keys in the usual manner.
In totai taking operations, both read and reset,
it is necessary that the shaft I06 make two clock
wise revolutions and the gear I02 one counter-'
wheels in a manner now to be described.
clockwise revolution. This is accomplished in 65
The Y-shaped cam arm I30 (Fig. 5)‘ has a the following manner. The pitm'an I1l carries a
roller I63 which cooperates with an arcuate sur
roll I85 normally retained in a notch in a cam
face on the beam I44 to force the beam against I86 but adapted to cooperate at certain times

70 viously described. This, through the link I46,
positions the segments I41 and I49 commensurate
with the position of the differential actuator I24,
thereby properly positioning the associated print
ing wheel. After the segment ‘I41 has been po
76 sitioned, an aliner I65 fast on a shaft I66 (Fig. 5)
ing add operations is retained immovable by
means of the roller I85 engaging the notch there
Loosely mounted on the shaft I61 (Figs. 3
and 9) is an arm I88, connected by a link I89 76
to the arm I12. The arm l99'has pivoted thereto
a link I90 having a'stud I9I which engages a slot _
in a plate I92 pivoted on. a stud I99 secured in
the frame I09. The link I90 has fast therein
another stud I60 arranged to cooperate with a
projection I6I on the arm I69. The plate I92
has another slot embracing a stud I99 in an arm
I95 of a yoke I96 loose on a shaft I91 (see also
Fig. 2). The yoke I96 is bifurcated to receive a
10 stud I99 in a link I99 connecting the upper ends
of key plates 200 and 20I mounted for slight
radial movement on studs 209 and 209 carried by
a total key frame 202 (Fig. 7).
A link 206 connects the lower ends of the plates
15 200 and 20I in exactly the same manner as the
link I99 connects the upper ends. Each plate 200
and 20I has three sets of slots 206, 201, and 209
(Figs. 2 and 9) arranged to cooperate with studs '
209 carried by a new balance key 2I0, total reset
keys 2I I, and total read keys 2| 2 (see also Fig. 7).
These slots are so arranged that each plate 200
and 20I receives a varying degree of movement
for each corresponding read and reset key ‘de
pressed. However, the combined movement of
both plates is always the same, and consequently
the stud I99 moves the same distance regardless
of which total key is depressed.
The arm I99 (Fig. 3) and connecting mecha
nism are retained in normal ine?ective positions
30 by. a spring 2I9 tensioned between an extension
of the arm I69 and one end of a lever 2| 9 pivoted
on a stud 2I6 secured in an auxiliary frame 2I6
supported by the frame I09. The lever 2I9 is
connected by a link 2I1to the arm- I99. Thus
35 the spring 2I9 retains the arm I99 in normal
position against the stop stud I99 and at times
when said arm and the shaft I61 ‘are rotated
in unison, their action is compensated for by the
link 2I1 so that no additional burden is placed
40 upon the shaft I 61.
Depression of any of the keys 2I0, 2I I, or 2I2
(Fig. 7) moves the plates 200 and 20I (Figs. 2
roller m gives the pitman in and mm m
added movement, thereby placing the link I19
in a position where the stud I19 is free to move
idly in the long part of the opening I19 when
the 'cam arm I90 is rocked by the raceway I92.
This prevents restoring the key lock shaft I61
during the ?rst cycle of operation, thereby allow
ing the machine to operate through another cycle,
near the end of which the cam I96 moves the
pitman HI and link I10 to a position where the 10
stud I19 will again engage the horizontal sec
tion of the opening I19 when the arm I99 is
moved downwardly, which restores the key lock
shaft I61 to normal ‘position and releases the‘
depressed transaction and total keys.
Add-subtract totalizer
The add-subtract totalizer embodied in this
machine is similar to that used in previous ma
chines of this type. There is an adding wheel 20
and a subtracting wheel for each denominational
unit (Figs. 4 and 5), corresponding wheels of each
denominational unit being geared together in the
well known manner so that they revolve in op
posite directions. These sets of add-subtract
totalizer wheels are loosely mounted on the shaft
I9I, which is in turn secured in a slidable frame
(not shown) controlled for engagement with the
differential actuators I29 in a manner to be later
described in connection with the auxiliary total

release pawl 229 on the shaft I91 and adapted to ‘ hub 916 and has pivoted thereto a beam 929
' cooperate with a release arm 229 secured on the
bifurcated to embrace a stud 921 in a link 929 ex
55 shaft I61. A spring 226 is tensioned to hold the
pawl 229 in the path of the arm 229.
Rocking the yoke I96 counter-clockwise by de
pressing any of the total keys, as explained above,
causes the arm 2| 9, ‘through the stud 2I9, to rock
the yoke 220 clockwise. This in turn rocks the
pawl 223 counter-clockwise to release the key lock
shaft I61 to the action of the spring I99‘(Fig. 3)
as explained above. The clockwise releasing
movement of the shaft I61 through the arm I69
rocks the arm I99 in unison therewith. Thisj
through the link I 99 and arm- I12, gives the shaft
I11 a slight movement clockwise and moves the
pitman I1I forwardly, causing the roller I96 to
move into the raceway I91 in the cam I96 and
70 couple'said cam to the gear I02 in the well known
manner. This movement of the pitman I 1| also
rocks the link I10 clockwise.
During rotation of the gear I02 and consequent
rotation of the cam I96 in unison therewith, the
16 raceway in said cam I96 cooperating with the
tending between an alining segment 929 and an 55
arm 930 of a printer drive segment “I lournaled
on the shaft I90. The segment 9291s secured to
a yoke 992 fast to the shaft I99. The segment
929 has a plurality of teeth 999 which cooperate
with the alining bar I66 secured to the shaft I66. 60
Again directing attention to Fig. 6, the beam
929 has an arcuate surface 996 which cooperates
with a roller 996 carried by the arm 920. A ?rst
transaction bank 991 has therein keys 999, 999., _
and 990. Depressing any of these keys places the 65
lower end of the stem thereof inthe path of the
arm 9“ to break the latch 9| 2 and differentially '
position the latch plate H0 and arm “9 com
mensurate with the depressed key. There is also
automatic means, to be explained later,» for breakq.
ing the latch 9I2 in its zero, third, ?fth, and
sixth positions. Unlike the other banks of the
machine, the ?rst transaction bank has no zero
stop pawl for breaking the latch 9I2 in its zero
position. Consequently, when none of the keys
Auxiliary totalizer mechanism
in this bank are depressed and the automatic
latch-breaking mechanism is ineffective, the
latch plate “8 and arm 4I3 travel to the ninth
position, where the latch is automatically broken
by means of a stud carried by the ?rst trans—
action bank frame engaging the end of the latch
Directing attention to Figs. 4, 5, and 8, the
auxiliary totalizer mechanism is supported be—
tween the plate 2 I6 and a-left auxiliary plate "I
plate 4I8. After the plate 4I3 has been dif
ferentially positioned by one of the means previ
ously described, 'the roller 436 engages the
arcuate surface 435 of the beam 426, forcing said
beam‘against a hub “I to differentially position
the segments 429 and 43I and the shaft I48
sists in supporting the auxiliary totalizer mech
anism. The auxiliary totalizer I40 is similar in
construction to the front and rear totalizers I38 10
and I39 and has six sets of interspersed totalizer
wheels rotatably mounted on a tube 413 secured
commensurate with the position of the arm M3.
The segment 43I is geared to a pinion 45!] fast
on a shaft 45I journaled between a pinion frame
452 and a ‘front printer frame 453 (see also Fig.
28). The shaft 45I drives a rack (not shown)
which positions the printing wheels for the ?rst
transaction bank 431 and also controls the auto
matic line-spacing -mechanism to be later de
Secured to the left end of the shaft I48, and
consequently rotated in unison therewith (Figs.
8 and 16), is an auxiliary totalizer shifting cam
442having an arm 443 connected by a link 444
to an add-subtract totalizer shifting cam 445,
pivoted on a stud not shown, carried by the
left frame I81. The stud which supports the
shifting cam 445 is on the same center as the
differential actuators I24. The cam 445 moves
in synchronous order with the cam 442, due to
its connection thereto, and as the cam 442 is posi
tioned by the latch mechanism of the ?rst trans
action bank, the cam'445 is likewise positioned ac
cording to the location of said ?rst transaction
bank latch mechanism. By referring to Fig. 16
it will be seen that both the cams 442 and 445
have'ten positions. The four upper positions of
the cam 445 shift the add-subtract totalizer frame
to the right (as viewed in Fig. 8, or to the\left as
viewed in Fig. 16) , thereby alining the plus set of
totalizer wheels with the actuators I24. The four
lower positions of the cam 445 shift the add-sub
tract totalizer frame to the left (Fig. 8) to aline
the negative set of totalizer wheels with the ac
tuators, The cam 445 has two neutral positions
which retain both the positive and negative sets
of totalizer wheels out of engagement with the
differential actuators I24.
From the foregoing description it will be seen
that when the latch “2 (Fig. 6) is broken in- the
zero, ?rst, second, or third position, the negative
side of the add-subtract totalizer will be selected
for engagement with the actuators, and when the
latch H2, is broken in the sixth, seventh, eighth,
or ninth position, the positive side of the add
subtract totalizer will be selected for engagement
with the di?erential actuators I24, andwhen the
latch H2 is broken in the fourthor ?fth position,
neither set of totalizer- wheels will be selected for
engagement with the di?erentials.
As previously stated, the mechanism which
shifts the totalizer lines I38, I39, and I4] laterally
secured to the left frame I01. The plate 2I6 sup
ports an intermediate plate 412 which also as- _
in arms .414 and 415, loose on an engaging shaft
416, the ends of which are supported in slots
(not shown) in plates 419 and 480 of the usual 15
type secured respectively to the plates 2I6 and
41I. Secured on opposite ends of the shaft 416
are arms 48I and 482 carrying anti-friction roll
ers which extend within duplicate cam slots of
the plates 419 and 488. The arm 415 (Fig. 8) 20
carries a pin 486 upon which is journaled a
?anged roller 481, the upper end of which is em
braced by a lateral slot 488 in a bracket 489 se
cured to the plate 41I.
The lower end of the
roller 481 extends within a slot 498 in the aux
iliary shifting cam 442 (see also Fig. 16). Move
ment of the cam 442 shifts the auxiliary totalizer
laterally to aline the selected set of totalizer
wheels with a plurality of di?erential actuator
segments 492. The auxiliary totalizer line is 30
guided in its lateral movement by the slot 488
in the bracket 489 and by the shaft 416.
The present machine is equipped with nine
amount banks and one over?ow bank. Conse
quently there are ten of the differential actuators Li
I24 (Fig. 5) and ten corresponding auxiliary actu
ator segments 492. Each of the segments 492 is -
rotatably supported by the shaft I48 in vertical
alinement with its corresponding actuator I24.
Corresponding actuators I24 and segments 492 40
are connected for concert movement by a link
493. Consequently the differential movement of
the actuator I24, which is controlled in adding
operations by the amount keys I I3, is transmitted
to the auxiliary actuator segments 492.
Automatic latch-breaking mechanism
The latch of the ?rst transaction bank, in ad
dition to being broken by means of the keys 438, “
439, and 440 (Figs. 6 and 15), is also broken au
tomatically in various positions. Itwill be re
membered that the ?rst transaction bank latch
controls the selection of the plus or minus side
1of the add-subtract totalizer and also controls
the selection of the different totalizers on the 55
auxiliary‘totalizer line in all operations including
add, read, and reset.
The ?rst transaction bank (row 1') latch has
ten positions, zero to 9 inclusive. Movement of
this latch controls the positioning of the cams 60
442 and ‘445 (Fig. 16) which in turn respectively
‘control the selection of different sets of totalizer
wheels on the auxiliary totalizer line and the plus

and'8I0, which cooperate with studs 209 in the
new balance or ?rst reset key 2I0 and the ?rst
read'key 2I2 (see also Fig. 15). The plate 808 is
bifurcated to embrace a stud 8“ in an arm 8I2
15 loosely mounted on the upper reset shaft I91.
The arm 8| 2 has a hook 8l8 which cooperates
‘with a square stud 8I4 in one arm of a. yoke 8I5
loosely mounted on a shaft 8I6, opposite ends of
‘which are journaled in the plate 464- (Figs. 6
'20 and 8) and a plate 8| 1., carried by the ?rst trans
action bank hanger H8. The plate 808 (Fig. 14)
has symmetrical slots 8I8, which cooperate withv
the studs 209 carried by the second and third
reset and read keys 2“ and 2I2 respectively. The
25 arm 8I2 carries a stud 8_I9 which cooperates with
' an arm 820 secured on a shaft 82I journaled in
the plates 464 and 8I1.' Secured on the shaft

When the machine is in home position, a spring
(not shown) retains the latch .826 in engagement
with an arm 821 fast on the key lock shaft I61.
Depressing any one of the keys 2I0, 2I I, and
2I2 rocks the plate 808 and the arm 8I2 counter
clockwise. This in turn rocks the shaft 82I and
arm 822 clockwise, which, through the arm 824,
moves the latch 826 counter-clockwise to release
the key lock line for its clockwise releasing move
ment, as previously described herein. Restora
tion counter-clockwise of the key lock line I61 ‘
near the end of- machine operation allows the
' vlatch826 to reengage the arm 821 to lock the
shaft I61 against releasing.
Depressing a key in either the ?rst, second, or
third transaction bank likewise rocks the latch
826 counter-clockwise, so that the shaft I61 will
50 be free to make its releasing movement clockwise
when the starting bar I08 is depressed. From
the foregoing it will .be seen that depressing one
of the keys 2I0, 21 I, or 2| 2 releases the machine
for operation, but before the machine can be

counter-clockwise. This moves the hook 8I8 out
of the path of the stud 8“, thereby surrendering
the yoke 8I5 to the control of other means to be

to aline the step 88I thereon with the stud 888
in the arm 884.
The purpose of the above move

Calling attention to Fig. 12, fast on the key
lock shaft I61 is an arm 888 connected by a link
840 to a plate 8“, rotatably mounted on the
shaft "I. A foot 842 of 'the link 840 cooperates
with the stud 888 to restore the arm 884 to nor
mal position near the end of each machine oper
ation in a manner to be described later. The
plate 8“ has ‘an arcuate surface 848 which coacts
with a stud 844 carried by one arm of a yoke 845
turnably mounted on the shaft 8I6. Initial re
leasing movement clockwise ofv the shaft I61
(Fig. 12) rocks the foot 842 of the link 840 away
from the stud 888 in the arm 884, and rocks the
plate 8“ counter-clockwise. This movement of 30
the plate 8“ disengages the arcuate surface 848
thereon from the stud 844 in the yoke 845 for a
purpose to be later described. The yoke 845 has
an extension 846 (Fig. 12) which cooperates with
a stud 841 in an arm 848 of the yoke 815. An
other extension 849 (Fig. 14) of the yoke 845
coacts with a stud 850 in an arm 85I secured to
the shaft 8I6. Secured on the shaft 8I6 is a
latch stop pawl 852 (Fig. 14), the end of which
is adapted to cooperate with a projection 858 on 40
the plate 4I0. Also fast on the shaft 8I6 is an
arm 854 carrying a stud 855 which coacts with a
projection 856 (Fig. 14) of a plate 851 mounted
for slight rocking‘ movement on the center I88.
The plate 851' has angular camming surfaces 858 45
arranged to be engaged by studs 859 carried by
the keys I48 (Fig. 15) of the third transaction
bank. The stud 841 in the arm 848 of the yoke
8I5 (Fig. 12) is arranged to be engaged by a ra
dial projection 860 on a plate 86I turnably 50
mounted on the center I88 and having angular
camming surfaces 862 which cooperate with studs
868 carried by the keys 438, 489, and 440 of the
