10 Claims,
(C1. 235—-8)
his invention relates to cash registers and
the like but is more particularly directed to re
peat mechanisms for such machines.
It is broadly an object of this invention. to de
5 vise a. unique repeat mechanism. for cash re€~
isters and like machine-s.
A more speci?c object is. to: contrive means
whereby the amount of the immediately preced
ing operation may be repeated without setting
10 up a condition to effect said repeating during
said preceding operation.
Another object is to provide means under con
trol of a manipulative device to lock the amount
differential members in the positions to winch
' they were adjusted in the preceding operation in
order to repeat the amount of said preceding op
eration.
Still another object is to provide an interlock
ing mechanism between the repeat starting bar
and the amount keys to prevent the depression
of both in the same operation.
A further object is to contrive means to pre
vent depression of the repeat starting bar when
the total control lever is out of adding position,
said means also adapted to lock the total con
trol lever in adding position upon depression of
the repeat bar.
With these and, incidental objects in view, the
invention includes certain novel features of con
struction and combination oi‘ parts. the essential
elements of which are set forth in the appended
claims and a preferred form or embodiment of
which is hereinafter described with reference to
the drawings which accompany and form a part
of this speci?cation.

GENERAL DESCRIPTION
The differential mechanism for each amount
bank of the machine embodying the instant in
vention comprises comp-anion scissors-like mem
bers with a complementary movement. In add 1O
ing operations these members position their as
sociated indicator and type wheel differential ac
tuators and the wheels of the selected tctalizer
commensurate with the value of the depressed
amount keys and said actuators in turn position 15
their corresponding indicating mechanism. and
printing wheels commensurate with the value
of the depressed amount keys. In this type of
differential mechanism the actuators are not re
turned to a neutral or Zero position at the end
of machine operation but remain in the positions
in which they were set by the companion mem
bers during the machine operation. Consequent
ly in the succeeding operation the actuators are
moved from the positions in which they were set
during the preceding operation directly to their
new positions.
In totalizing operations the cor
responding wheels of the selected totalizer po
sition the scissors-like companion members com
mensurate with the amount on said totalizer ‘
wheels and said companion levers in turn posi
tion the actuators and the actuators in turn po
sition the indicators and the type Wheels com
mensurate with the amounts on the Wheels of the
totalizer.
For a full disclosure of the differential mech
anism outlined above reference may be hadto
Letters Patent of the United States No. 1,792,569
and No. 1,899,455, issued respectively February
17, 1931 and February 28, 1933, to Ernst Breit
ling.
If it is desired to repeat the immediately pre
ceding operation, the operator depresses the re
peat starting bar, or in the modi?ed form moves
the total-control lever to repeat position. This. 45
actuates. mechanism that locks the indication
and type wheel differential actuators for‘ the
amount banks in the positions in which they were
set in the preceding operation. The actuators
then position the companion levers to repeat the
amount of the preceding operation.
With this. type of repeat mechanism an amount
may be repeatedly added in one or more totalizers
and amounts may be transferred from one total
izer to one or more of the remaining totalizers

many of the i. all known machines of this type
it is necessary that the operator have knowledge
of a succeed’ng repeat operation in order to set

Amount keys and their associated differential
mechanism
The instant machine has a plurality of de
30
nominational amount banks 32 (Figs. 1 and 4)
supported by a rod 33 and a bar 34 extending be
tween the frames as and 3!. Inasmuch as these
amount banks and their associated differential
35 mechanisms are exactly alike, it is believed suffi
cient to describe one such amount bank and its
associated differential mechanism.
Depressing one of the amount keys 35 moves
the lower end of the stem thereof in the path of
40 a plate 37 secured to a main differential lever 33
and also moves said stem in the path of a nose
39 of an auxiliary differential lever 40, both of
said levers being pivotally supported on a shaft
4| journaled in the frames 35 and 3!. The seg
mental lower end of the main lever 33 (Figs. 1
and 4) has therein teeth which mesh with a sec
tor 42 secured to a differential sun wheel 43 turn
ably mounted. on a shaft 44 opposite ends of which
are journaled in the frames 30 and 3 l. The aux
iliary differential lever 40 has a segmental ex
tension with gear teeth which mesh with a sec
tor 45 loose on the shaft 44 and forming a sup
port for a planet wheel 46 which connects the
sun wheel 53 to
similar sun wheel 4'5, secured
to the shaft 44.
Depressing an amount key 35 causes a stud 133
thereon, in cooperation with. an angular slot in
a control plate 49, pivotally connected b sym
metrical links 58 and 5! to the key Fame 32, to
60 impart clockwise rocking movement to said con
trol plate ‘is. Clockwise movement of the con

Repeat mechanism
The
amount of the preceding operation,
whether the result of an adding or a total taking
operation, may be repeated in succeeding ma
chine operations by means oi a manipulative de
vice that locks the plate
in its pro-set position
and thus the stud 5‘! controls the p, tioning of
the differential levers 38 and 45 exactly as they
were controlled during the precerl'tg operation
by the depressed. amount key. It

unnecessary as well as u desirable to depress
amount keys in repeat opera .ons and to prevent
this an interlocking device rendered effective by
the repeat manipulative member locks the
amount keys against dQI'Ll'l'ioslOl'i during repeat
operations.
In its pref ‘Fred form the present machine is
provided with two starting bars (Fig. 52), regu
lar starting bar
and a repeat starting bar 66.
The regular starting bar 65 is used to release
the machine for o‘ ation in all operations e2;
cept repeat operat. ns.
Depressing the repeat bar 86 by means of a
stud
therein, in cooperation with an angular
slot 68 in a control plate
imparts counter

' clockwise movement to said control plate. The
plate 69 is rockably mounted on a frame ‘ID, that
supports the starting bars 65 and 66, by means
of a lever 1| pivoted at 12 to the frame 10 and
a link 13. counterclockwise movement of the
plate 69 and incidental similar movement of the
lever l| moves a rearward extension of said lever
away from a stud 14 secured in one arm of a
bell crank 15 fast on a sleeve 16 loose on a rod
10 11 supported by the frames 30 and 3|.
Also secured on the sleeve 16 is an arm ‘I8
connected by a rigid bar 19 to a similar arm 80
ing bar 19 out of engagement with the teeth
in the di?erential plate 59. Return movement
clockwise of the plate 69 by means of the pitman
8| and the bell crank 811 (Figs. 1 and 2) returns
the rod 88 also clockwise to permit the zero stop
pawl 53 to be returned counterclockwise to effec
tive position by the spring 55.
It is obvious from the foregoing description
that by simply depressing the repeat starting bar
5% the amount of the preceding operation may be 10
repeated for the purpose of entering said amount
in one or more of the machine totalizers.

repeat starting bar
Depressing one of the amount keys 35 (Fig. 1)
actuates interlocking mechanism that prevents
depression of the repeat starting bar 56 (Fig. 2)
ing the preceding machine operation.
In adding operations, depressing an amount
key rocks the zero stop pawl 53 (Fig. 1) out of
the path of the lever 38.
However, as no amount
key is depressed in repeat operations, it is neces
sary to provide other means to rock the Zero stop
pawl 53 to ineffective position. A pitman 8|
(Fig. 2) one end of which is pivoted to the plate
and likewise depressing the starting bar 66 actu
ates the interlocking mechanism to prevent de
pression of an amount key 35. This interlocking
mechanism will now be described.
Pivoted to the upper end of the control plate
49 (Fig. 1) is a pitman 38, the upper end of
which is bifurcated to embrace the rod 82. The
pitman 98 carries a pin E39 adapted to cooperate
69 and the other end of which is bifurcated to
straddle a rod 82 extending between the frames
30 3i! and 3| moves in unison with said plate 69
upon depression of the repeat starting bar 66.
Movement of the pitman 8| by means of a stud
83 therein in cooperation with the forked upper
end of a bell crank 84 ‘secured to one end of a
Cu CA sleeve H5 loose on a rod 85 extending between
the frames 30 and 3|, imparts counterclockwise
movement to said bell crank 84. The lower end
of the bell crank 84 is bifurcated to embrace a
stud 35 in an arm 81 loose on the sleeve H6 and
40 connected by a transverse rod 88 to a similar
arm 89 (see also Fig. 4). It is therefore obvious
that the arms 81 and 89 and the rod 88 move
with an arm ind,
ecured to a sleeve iiil, loose
on a rod I82, supported by the frames 36 and 3|.
Also secured to the sleeve iEi| (Fig. 2) is an arm
H33, adapted to cooperate with the stud 83 in 3O
the pitman 8|.
Depressing one of the amount keys 35 moves
the control plate 619 and the pitman 98 upwardly,
causing the stud S9 to impart counterclockwise
movement to the arm Hit, the sleeve it); and the "
arm 583.
This moves the arm 5 3 into contact
with the stud 33 thereby blocking downward
movement of the pitman 3i and the control bar
69 to obstruct depression of the repeat bar 59
40
when an amount key is depressed.
Likewise depressing the repeat starting bar 66
moves the stud 83 into contact with the arm “33
to block counterclockwise movement of said arm
and the arm iilii (Fig. l.) to prevent depression
of an amount key 35 when the repeat starting 45

the periphery of the cam 90, in cooperation with
a stud 32 in the bell crank 15, rocks said bell
crank counterclockwise to disengage the locking

Also near the end of
machine operation the repeat starting bar 66 is
released and is springereturned upwardly to un
depressed position. Return movement of the
repeat bar 56 causes'the stud. 61 in cooperation
with the angular slot 68 to return the plate 69

49, the pitman 98 and the stud 99 upwardly to
impart clockwise movement to the arm I I I, the
sleeve I I0 and the arm I09. Clockwise movement
of the arm I09 moves the extension I08 into the
slot I0'I to lock the total control lever in adding
position when an amount key is depressed.
A
spring II2 normally maintains the extension I08
out of the slot I0‘I when an amount key is not
depressed and urges the arm III counterclock~
wise into contact with the stud 99. When the
total control lever I04 is away from adding posi
tion the slot I0‘! is out of alinement with the ex
tension I 08 and the periphery of the disk I06
blocks clockwise movement of the arms I09 and
15 I I I to prevent depression of an amount key 35.
The disk I06 has another arcuate slot I I3 which
coincides with a bent-over projection I I4 of an
arm II5 when the total control lever I04 is in
adding position. The arm II 5 is secured on one
20 end of the sleeve II6 to the other end of which is
secured the bifurcated bell crank 84 (Fig. 2).
The sleeve I I6 is rotatably mounted on the sleeve
II 0 which is turnably mounted on the rod 85.
Depressing the repeat starting bar 66 imparts
26 downward movement to the control plate 69 and
the pitman 8| causing the stud 83 to rock the
bell crank 84, the sleeve H6 and the arm II5
(Fig. 3) counter-clockwise to move the projec
tion II4 into the slot II3 to lock the total con
30 trol lever I04 in adding position when the repeat
bar 66 is depressed.
Moving the total control
lever I04 out of adding position moves the notch
II3 out of alinement with the projection II4,
permitting the periphery of the disk I06 to block
35 counterclockwise movement of the arm I I5, which
by means of the sleeve H6 and the bell crank 84
blocks downward movement of the pitman BI
and the control bar 69 to prevent depression of
the repeat release bar 66 when the total control
lever I04 is out of adding position.
MODIFIED FORM
A modi?ed form of repeat mechanism is illus
trated in Figs. 5 and 6, in which a total control
lever II9, similar to the total control lever I04,
has four positions—viz., “Add”, “Read”, “Reset”
and “Repeat”.
When the total control lever
H9 is in “Repeat” position, the amount keys
are locked against depression and the differential
50 control plate 59 is locked in the position to which
it was adjusted in the preceding operation. De
pressing the regular starting bar 51 sets the ma
chine in motion to repeat the amount of the pre
ceding operation. It will be understood that
55 moving either the total control lever I04 of the
preferred form, or the total control lever II9
of the modi?ed form, away from adding position
rocks the zero stop pawl 53 (Fig. 1) to ineffec
tive position, in order that the stud 51 in the plate
60 59 may position the companion scissors levers
38 and 40 in the manner explained hereinbefore.
As in the preferred form, the total control le
ver I I9 has a segmental portion with teeth which
mesh with a gear I20 secured to a control disk
I2I rotatably supported by the rod 9|. The disk
I2I (Fig. 5) has in the left face thereof a cam
ming groove I22 into which extends a stud I 23
carried by an arm I24 secured to the righthand
end of a sleeve I25 revolvable on the rod 11.
70 Secured to the left end of the sleeve I25 is an arm
I26 which supports one end of a transverse look
ing bar I21, the other end of which is supported
by an arm (not shown) similar to the arm I26,
and loose on the rod 11. The arm I26 and the
locking bar I21 are similar to the arm ‘I8 and
the locking bar "I9 (Fig. 2) of the preferred form,
and the locking bar I21 cooperates with the teeth
on the upper portion of the plate 59 in exactly
the same manner as the bar 19.
The con?guration of the cam groove I22 is
such that when the total control lever H9 is
moved to “Repeat” position, clockwise movement
is imparted to the arm I24, the sleeve I25, the
arm I26 and the locking bar I21, to engage said
locking bar with the teeth of the differential 10
plate 59 to lock said plate in the position to which
it was set in the preceding operation. Releasing
the machine for operation by means of the
starting bar 65 causes the amount of the pre
ceding operation to be repeated in the manner 15
explained above. It will be noted that when the
total control lever H9 is in “Add”, “Read”, or
“Reset” position the cam groove I22 maintains
the locking bar I21 out of engagement with the
plate 59.
20
The disk I2I has an arcuate slot I28 which is
alined with the extension I08 of the arm I09
when the total control lever I I9 is in adding posh
tion. Depressing an amount key 35 (Figs. 1 and
5) through the plate 49, pitman 98 and Stud 99 25
rocks the arm III, sleeve H0 and arm I09 clock
wise to engage the extension I08 with the slot
I28 to lock the lever H9 in adding position. Mov
ing the lever Il9 away from adding position ro
tates the disk I2I clockwise to move the slot I28 30
out of alinement with the extension I08 and the
periphery of the disk I2I obstructs clockwise
movement of the arm I09 to prevent the depres
sion of an amount key 35.
