2 Claims.
(Cl. 235-60)
The invention has relation to listing calculators
and more particularly to means for temporarily
modifying the action of a program mechanism
controlling the activity of and the sign character
5 of registration upon a plurality of accumulators.
The invention consists in the novel construc—
tion and combination of parts, as set forth in the
appended claims.
.
The invention is'shown as applied to a calculat
10 ing machine constructed in accordance with the
disclosure'of my U. S. Patent No. 1,932,013, is
sued October 24, 1933, and entitled “Registers”,
2I4. The various movements of the segments 6 I 0
in a counter-clockwise direction has served to
adjust printing type mounted on type bars SII
pivotally connected to the segments BIO, this
movement servingto bring type representing the 5
appropriate digits to the printing line.
Means are also provided for throwing the
pinions of accumulators No. I, No. 2, No. 3, and
No. 4 into mesh with the segments 6| 0 either
during the forward stroke of said segments, to lil
eifect subtractive registration on the accumula
tors, or during return stroke of the segments I
to eil‘ect additive registration thereon. This
the program mechanism employed being in ac
cordance with the disclosure ‘of my U. S. Patent _ means comprises a series of cams on the register
UI No. 1,946,572, issued February 23, 1934, and en- ,
titled "Listing calculators.”

Accumulation
Referring to Fig. 1, amounts set on the keys 2I5
are registered in the accumulators No. I, No. 2,
vNo. 3 and No. 4 upon operation of an electric
40
motor I00 having driving connection with rock
shaft 30I, which is connected with a frame BIG
by means of spring held latching dogs GI‘I.
Reciprocation of shaft 30I by operation of motor
45 I00 will therefore rock the frame GIG, ?rst in a
counter-clockwise direction as viewed in Fig. 1,
allowing segments 6I0 to move counter-clock
wise about shaft 608, and thereafter the return
movement of shaft 30I will effect clockwise move
50 ment of the parts. The extent of these move
ments is determined by engagement of a stop bar
6I5 pivotally connected to the segments GIO, with
the end of a depressed key 2 I 5. The segments 6 l 0
related to key columns wherein no key has been
65 depressed are held inactive by means of zero stops
shafts 403 and a series of cooperating cams con- 1!
nected with rocker plates 4I9 (Fig. 2) so ar
ranged that when the high points of the cams
upon the shaft 403 register with the high points
of the cams connected with the plates M9, the
register pinions will be moved into mesh with the 20
segments 6I0, against the tension of suitable
springs, the register shafts being guided in the
movements into and out of mesh with the seg
ments by engagement with the walls of suitable
25
slotted recesses in a ?xed frame plate.
As shown, the two upper accumulators, No. I
and No. 2 are capable of additive or subtractive
registration, while the No. 3 and No. 4 accumula
tors are designed for addition only. Any of the
accumulators may be disabled, or adjusted to 30
non-add condition by appropriate location of the
cams carried by the shafts 403.
.
In order that the No. I and No. 2 accumulators
may be set for addition or subtraction, the shafts
403 of these accumulators are provided with two 35
cams I2I and I22 projecting from the shaft in
different ‘angular directions. Thus rotation of
shaft 403 will move the cams I2I out of register
ing position and the cams I22 into registering
position, a further rotation of the shaft moving 40
both cams out of registering position. Two plates
“9 are-shown, connected by a pin and slot device
for movement in opposite directions. Each plate
“9 is provided with cams I24, lying in the plane
of and cooperating with the cams I22, and cams 45
438, lying in the plane of the cams I2I. The
plates 4|! are rocked to change the position of
the cams I24 and 438 relative to their cooperat
ing cams at the end of the forward stroke of the
segments, and may also be rocked at the beginning 50
of the registering operation, one of the plates 4I9
having link connection with a rocker 325 for this
purpose. Rocker 325 is controlled by two cam
arms 3I6 and 320, secured upon rock shaft 30I,
the arm SIG being adapted to engage a cam fol-~ 55
2,184,280
lower pivoted upon the rear end of rocker 325
.and arm 320 adapted to engage a similar cam
follower pivoted upon the forward end of the
rocker. Fig. 2 illustrates rocker 325 in its condi
tion of normal operation, in which adjustable
plate 328 is so positioned as to prevent counter
clockwise pivotal movement of the rear cam fol
of said plate from engagement in rear of said
pin. A cam face plate 328 also engages a pin in
the upper end of the rear cam follower and rocks
said follower pivotally out of the path of move
ment of cam arm 3l8.
~
'
Therefore, during a total taking operation cam
arm 320 will rock the forward cam follower piv
otally during the forward stroke, without mov
ing the rocker 325, thereby leaving the cams 438
lower and to prevent clockwise pivotal move
ment of the forward cam follower, this plate being
10 adapted to rock with rocker 325. At the beginning
.» opposite the cams I 2I. During the return stroke
of a registering operation cam arm 328, con
forward cam follower and-move the rocker 325

gagement with the cams I2I, so that the registers
15 I24 thereof into registering position.
the cooperating cam I 22 is in inactive position,
and, since the cam 438 was moved away from cam
I2I by the rocking of plate “8, the No. I ac
cumulator will be allowed to move out of mesh
20 with the segments, and no subtractive registra—
tion will occur therein. No. 2 accumulator how
ever is set with cam I22 in operative position, and
the rocking of plate “9 will bring cam I24 into
contact with cam I 22, so that the No. 2 accumu
25 lator will be thrown into mesh and subtraction
will be effected. In the beginning of the return
stroke of the cam arms 3I8, 328, arm 3I5 will con
tact with the rear cam follower and will move the
rocker 325 back into the position illustrated in
30 Fig. 2, wherein the cams I24 will be moved to
inactive position and the cams 438 into active
. position, so that addition will be effected on the
No. I accumulator, while the No. 2 accumulator
35
is allowed to move out of mesh.
The No. 3 and No. 4 accumulators are provided
with cams I35 made each in the form of a disk
having a ?attened side I38. In Fig. 2 the ?attened
side I36 of the cams ‘I35 are shown as lying op
posite the cooperating pawls I31, so that no regis
tration of these accumulators No. 3 and No. 4 will
be effected. One of the pawls I31 has link con
nection with one of the plates “8, and also en
gages at its free end with the free end of the
other pawl, so that upon movement of the plates
45 4| 9 both of these pawls will drop away from the
cams I35, and will be returned into the position
shown in Fig. 2 at the beginning of the return
stroke of the segments. Therefore, if the cams
I35 have been adjusted to bring their semi-cylin
50 drical walls opposite the pawls I31, the No. 3
and No. 4 accumulators will be moved into mesh
at this time and addition will be e?ected.
Total taking
The total standing in any one of the registers
may be cleared therefrom and printed on the rec
ord sheet by engaging the pinions 412 of the reg
ister with the segments 8| 8 and moving the seg
ments subtractively until zero stops 451 of the
60 register units engage cooperating stops 6I3 which
have been brought into their path of movement.
This serves in well known manner to subtract the
total from the register and to set it in the type
bars 6| I.
65
The total key 218 which controls this opera
tion is designed to reverse the effective action of
the cams I24 and 438, so that a register which
has been adjusted for additive accumulation will
need no adjustment when a total is taken there
70 from. For this purpose a projection of the total
key lever engages a pin 352 on the plate 326, and
readjusts said plate relative to rocker 325, this
readjustment bringing the lower hook end of plate
328 in front of the pin in the upper end of the
76 forward cam follower and removing the shoulder
0
of the segments, cam arm 328 will engage the
tacting the forward cam follower will move the
rocker 325 in clockwise direction as viewed in
and plates 4I9 to remove the cams 438 from en
which are set for additive accumulation will move
out of mesh with the segments. Accumulators
in which the cams I22 had been set to active
position during the taking of the total from an
other accumulator will be thrown into mesh dur
ing the second or additive stroke of the segments, 20
and will accumulate the total cleared from said
other accumulator.
‘
In the machine illustrated, the upper or No. I
accumulator is a “cross footer”, designed to ac
cumulate the values entered into each of the 25
other accumulators during a single series or line
of entries. No. 2 accumulator is customarily a
debit register, and is set for subtractive opera
tion, it being noted that a complementary value
will stand on this No. 2 accumulator, and that 30
the addition of this complementary value to an
other (the No. I) accumulator during the taking
of a total will be equivalent to the subtraction
of the true amounts registered in No. 2 accumu
lator from the amounts registered in No. I ac 35
cumulator. Thus a “vertical total" or a total of
all of the entries in each of the accumulators No.
2 to No. 4 may be taken, these totals being trans
ferred to the No. I accumulator to show a grand
total.
Program mechanism
40
Means are provided for setting the various ac
cumulators to add, subtract or non-add, in ac
cordance with the tabular position of the record
carriage. This comprises means for rotating the
register shafts 483 to position the cams I2I. I22,
and I35 to the desired positions. For this pur
pose a perforated tube 82 (Figs. 3 and 5) mount
ed in the transverse and shiftable record carriage
cooperates with feeler devices in the frame of
the machine. The feeler devices include plung
ers 83 and 84, designed to register with the per
forations of the tube 82. The plungers 83 related
to No. I and No. 2 accumulators are provided
with reduced end portions, joined to the body of 55
the plungers by shoulders. The perforations in
the tube 82 are of two sizes, corresponding to the
reduced and enlarged portion of the plungers 83,
the larger perforations also corresponding to the
diameters of the plungers 84.
60
The plungers being moved toward the tube 82
will be immediately arrested, if no perforation
of said tube is in line with the plunger, whereas
if a large perforation of the tube 82 is opposite
the plunger, said plunger will move freely to its 65
full extent of movement. If a small perforation
of the tube 82 is opposite one of the plungers 88,
the shoulder of the plunger will contact with the
marginal walls of the perforation and the plunger
70
will be held in an intermediate position.
The plungers 83 and 84 are mounted upon in
termediately pivoted levers 88, the opposite ends
of these levers being connected by links 96, levers
83 and yieldable spring connections 84 with plates
' 3
2,134,2so
89. _ Plates 69 are rocked through link 6‘! and
crank arm 58 secured upon a rotary shaft 56 ca
pable of being driven from the motor Hill. Upon
operation of shaft 56 therefore the plungers 83,
at will be moved rearward toward tube 82, and
will be positioned by abutment with said tube in
one of three positions.
Levers 93 are provided
with lugs 98, these lugs taking one of three posi
tions, in accordance with the position of the re
way position, in‘ which the shoulder of the plunger
engages the marginal wall of a small hole of the
tube 82. The effect is to set the No. l accumulator
into subtracting position and the No. 2 accumu
lator into adding position. A second step of
counter-clockwise adjustment of these shafts 403
will render the adding cam 12! of the No. 1 ac
cumulator active and the subtracting cam I22 of
10 lated plunger, so that the lugs are brought under
the surface 9a of a dog ‘M, under the surface m2
of a dog ‘it or to a position immediately beneath
a shaft lid supporting the dogs ‘l3 and ‘Ill. Nor“
inally dogs ‘l3 and it are locked in position by one
15 gagement of a roller "ll of the plate Gil with the
upper or with the lower surface of the dogs. Upon
movement of the plate 69 however roller ‘ll will be
moved out of engagement with the dogs ‘l3, id,
and these dogs will be allowed to assume the posi=
20 tion illustrated in Fig. 3, under the influence of
a connecting spring. However, if the lug so of
a lever 93' has been positioned by the related
plunger under the surface 99 of dog ‘it, the spring
so will cause the dog to be moved downwardly,
25 until the point of the dog lies below roller ‘ll.
Continued rotation of shaft llii will roclr the plate
so in an opposite direction, and the roller ll act»
ing upon the dog “id will bring the dogs into the
position illustrated in Fig. 4. Contact of lug Sit
. with surface ill?! of dog ‘ill will position said dog
so that it will be moved upwardly by action of
roller ‘ll. Dog 13 contacts with a lug lit of a
segment W5, and dog ‘it contacts with an oppo»
site lug l is of said segment. Therefore the posi~=
tioning or the two dogs on opposite sides of the
roller "i i , as shown in Fig. 3, will hold segment ME
in a central position; location of the dogs below
the roller ‘ll. as seen in
a, will position the
segment lull in a lower position, and location oi’
40 the dogs above the roller ‘M will raise the seg
ment. There are four pairs of dogs ‘iii, 14 and
four segments W5, each segment being engaged
the No.
accumulator active, this being the posi
tion taken upon movement oi the plungers 83 into 10
the large perforations of the tube 82, and also
being the position oi the cams illustrated in Fig. 2.
All oi the mechanism heretofore described is dis
closed in the ‘Patents 1,932,013 and 1,946,572,
hereinbefore referred to, but the opposite ar
rangement of the cams iii ‘and 12,2 of the No. l
and No, 2 accumulators is novel, and has been
combined with. the program modifying means now
to be described for shooting certain new results.
20
Program modifying devices
Means are provided whereby the operator may
modify the adjustment of certain of the accumu~
lators called for by the program mechanism in
any particular tabulated position of the record 25
carriage.

For this purpose a cylinder 38d (Figs. 3, 5 and
7) is rotatably mounted in the frame or‘ the ma
chine, saiol cylinder being notched as at 38i to
provide seats for the stop lugs 382 of slides 38%. 36)
Normally these slides are held out of contact with
the cylinder 3%, by means oi‘ a lever 385 having
a spring 386 adapted to hold an arm 38‘! or said
lever against lugs ii’dil of the slides. Lever 385
extends above theireyboard or" the machine, and 35
when moved rearwardly by the operator, against
the tension of the spring 386, springs 384 of the
slides 3833s are tensioned and will serve to move
the slides downwardly into contact with the cyl
inder 33%. If cylinder set has been adjusted so 40
that a notch 38!! is below one of the lugs @282,
the related slide 38$ will be allowed to move down
wardly into its operative position, in which the
lower end of the slide will lie in the path oi’

There are two series of slides 33%, comprising a
accumulators, since the plungers thereof are not
with a pinion U32: mounted upon a universal
jointed. extension or one of the accumulator shafts

adapted for intermediate adjustment. ‘When the
rearward series lying adjacent the pins see, and.

The slides 383 or the forward series are spaced

ment of the accumulators, while movement of a
plunger all into a perforation. oi tube all will movev
the cams 835 into position to cooperate with the
60 pawls llll, providing for addition on the related
accumulator.
.
.
The cams H26 and 522 of the No, l and No. 2 ac»
cumulators are arranged in diiferent angular po»
sition upon their shafts. That is to say from a
65 position of adjustment or the shaft E93 wherein
neither cam l2i nor H22 is in active position, a
one-third rotation of the shalt 403 of the No. i
accumulator in a counter-clockwise direction as
viewed in Fig. 2 will bring the cam 622 into active
position, whereas a similar movement of the shalt
403 of the No. ll accumulator will bring the corn
Iii into active position. This one step of coun
ter-clockwise movement is effected by movement
of a plunger 83 irom its non-add position, against
75 the nnperiorated surface oi‘ tube 62, into its midr
from the related pins 389 by distance correspond»
ing to the movement oi? the feeler plungers into
contact with the marginal walls of the small per
forations oi the tube or. Therefore, the slides
661)
3828 oi‘ the rearward series are adapted to hold
the feelers in non-add position, while the slides
383 of the iorward series are adapted to hold the
No. i acculator in adding position regardless
of whether the feeler plungers register with a 65
small or with a larger perforation of tube 82.
In the machine illustrated, slides 383 are pro“
vided for the feelers or’ the No. i and No. 2 ac-'
cumulators, and the guide rods 390 between which
the slides are mounted are provided with seats
for slides 383 related to the No. '8 and No. ‘3 ac
cumulators, and designed to hold such accnmu"
lators in non-add position, Such additional slides
383 would be duplicates of the slides of the rear»
ward series related to the'No. i and No. 2 ac

2,134,230
cumulators, and would not necessarily be pro
vided in any given machine.
The cylinder 380 is provided with notches 38l
opening in different angular positions about the
axis of the cylinder, so that rotation of the cyl
inder, by means of a hand knob 39l will bring dif
ferent combinations of notches under the lugs
382 of the slides. The tube 82 is adjustable into
different angular positions, to bring di?erent se
10 ries of perforations in line with the plungers 83,
84, so that different programs are provided for,
these programs being customarily numbered
upon the tube adjusting members. Similar num
bers may be applied to the knob 33L so that the
15 cylinder 380 may be set into position to correctly

As an illustration of the utility of the program
20 modifying mechanism, let it be assumed that it
is desired to print and accumulate credit items
in the No. 3 and No. 4 accumulators; debit items
