Improvements in Cash Registers or Check Tills.
1, EDUARD RUNGE, of 31 Bruckenallee, Berlin, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to a cash register with adding apparatus, the key board
of which has a key for each of the different rows or series of figures, for example,
for the units, tens, hundreds, etc. by depressing which key by means of suitable
key levers there is rotated, in addition to the accounting disc, also a suitable
number drum of an indicating device through a suitable angle, so that the number
corresponding to the key struck becomes visible through an aperture. This in-
vention also relates to devices for limiting the stroke of the key levers, and also
to devices by means of which, whilst the depressed key levers are temporarily
locked, the numbers on the numbered drums which are rendered visible each time
through the apertures can be read off and checked before the numbered drum³
are moved back into the original O position. The arrangement is such that the
disengagement and locking of the keys depends on the opening and closing of
the lid of a till or money draw, whilst devices may be provided for rendering the
operation of the key levers impossible whilst the till is closed, so that said operation
can only be effected on opening the till. In combination with the cash register
in accordance with the present invention there may be further provided a printing
apparatus with a numbering mechanism, the type wheels of which are set to
correspond with the numbered drums of the cash register and which produce an
inipression or copy of the numbers indicated by the cash register upon a checking
strip which remains inside the machine and also upon a receipt form which is
to be handed to the purchaser. The invention further comprises the arrangement
of step by step or ratchet mechanism for the numbering discs of the adding
apparatus, which should be so arranged as to prevent the numbering disc that is
to be advanced from being rotated after each advance movement beyond the stroke
necessary for such advance movement.
The accompanying drawings illustrate by way of example a cash register which
is provided with the improvements forming the subject of this invention.
Figure 1 is a sectional end elevation of the cash register with closed till and with
the key levers locked by means of the latter.
Figure 2 is a part elevation of the devices for temporarily locking the key levers
after the same have been depressed.
Figure 3 is a front elevation in partial longitudinal section according to Figure 1,
in which there are five similar step by step or ratchet sets for indicating numbers
of one to five places of figures, and in which the casing, the key rods, and several
other parts are omitted for the sake of clearness.
Figure 4 is a separate view of the devices for limiting the stroke of the key
levers.
Figure 5 is a plan of the devices shown in Figure 4.

of the ratchet mechanism) of the counting discs.
Figure is a separate view illustrating the arrangement of two co-operating
number drums with the apparatus serving to advance the same step by step, in
front elevation.
Figure 8 is a separate view showing a part of the printing apparatus in its
operating position.
Figure 9 illustrates the connection of the printing apparatus with the other
parts of the apparatus in a position of rest.
Figure 10 shows the step by step or ratchet mechanism according to Figure 6,
at the end of its operation.
Figure 11 is a partial plan according to Figure 9.
In the arrangement shown in the drawings, the apparatus is provided with five
ratchet sets I, II, III, IV, V; each set comprises an adding apparatus with advance
movement for the tens, and an apparatus for indicating for the purpose of checking
the numbers that are rendered visible, said numbers being borne by two indicating
drums, one for checking by the seller and the other for checking by the purchaser.
The several ratchet sets can be operated independently of each other but are
connected together by the ratchet mechanisms. Each compartment or set is pro-
vided with a key 1 which is connected (preferably in an elastic manner by means
of a spring 4) with a rocking lever 3, which is mounted loose on a shaft 2, that
is common to all the sets. The rocking lever 3 carries a pawl 5, which engages
in the teeth of a ratchet wheel 6, that is mounted upon the shaft 2. The ratchet
wheel '6, is connected in a suitable manner with the counting disc of the adding
device, as will be described hereinafter.
The devices for limiting the stroke of the key levers 3, are arranged as follows:
-On the rocking lever, there is pivotted a pawl 7, in such a manner that ou
striking against a suitable stop it can be caused to engage with the teeth of the
ratchet wheel 6, (Figure 2) and thereby prevents further movement of the latter,
whilst normally it is raised by means of a spring 8 or the like from off the ratchet
wheel (Figure 1). Within the range of movement of these pawls 7 there are
arranged tipping shafts w² to w which preferably extend through the whole
of the sets (IV) and are provided on their lower sides with grooves such that on
the rotation of the rocking lever 3 of any one of the ratchet sets, the free end of the
corresponding pawl 7 can slide in the said grooves when the tipping shafts wl to 08
are in their normal positions. Each tipping shaft to is provided with a
tappet (Figure 4). At a suitable point of the apparatus there are arranged
spring keys or press knobs & to 18 (Figure 4) which co-operate with the tappets d
fo the shafts wi to . On depressing one of the press knobs for example, the
corresponding shafts to is turned over so that the groove a moves out of the path
of the pawl 7 and the solid or full surface of the shaft w enters the said path.
Consequently on a rotation of the rocking lever 3, the pawl 7 meets an obstacle
in the tipping shaft w which is turned over by the press knob 7, so that its lower
arm enters the teeth of the ratchet wheel 6 and locks the latter.
The arrangement shown is provided for reproducing the numbers of the decimal
system.
The shaft to 10 with their corresponding press knobs to correspond to
the numbers 1 to 8. The normal position of the rocking lever 3. corresponds to
the Figure 0. For the Figure 9, a full or solid fixed shaft to is provided which
forms the limit for the greatest stroke of the rocking lever 3. For this shaft 10'
there may be provided if desired for the purpose of completing the key-board of
the apparatus a fixed or blind" key (Figure 4). In order to return the rocking
lever 3 into its initial position after each stroke produced by the depression of the
key 1, there is employed a spring 18 which is fixed to the arm 17 of the rocking
lever and which is tensioned by rotation of the rocking lever and has then the
tendency to turn the rocking lever back in the opposite direction. Movement
beyond the O position is prevented by means of a stop 19. In front of the shaft zo'

page_text: there is further provided a tipping shaft w such that in the position of rest of
the apparatus it turns its full or solid surface towards the pawl 7, so that automatic
or unintentional movement of the rocking lever and of the ratchet wheel 6 froin
the position prevented. On the rotation which takes place in the manner
hereinafter described, of the shaft w, a groove a in the same is turned towards
the pawl 7 so that the latter can then slip through the same.
The rocking lever 3 is provided with a toothed are 9 which engages with a
toothed wheel 10 the axle II of which carries the numbered drums 12 and 13 of
the indicating apparatus. The figures on the numbered drums 12 and 18 are
visible through openings 14 and 15 of the casing 16, one opening being turned
towards the purchaser and the other towards the seller. On the rotation of the
rocking lever 3 the devices herein described move with them the number drums 12
and 13 so that the required figures on the number drums 12 and 13 become visible
each time through the apertures 14 and 15. When the rocking lever 3 is in the 'O
position the Figure 0 is visible at the apertures, and when the key k is struck,
the Figure appears, and so on. The tipping or rocking shaft which locks
the rocking lever 3, and the ratchet wheel 6, in the O position, is connected by
means of a rod 20, with a rear shoulder 21 of the lid of the till 22 in. such a
manner that when the till is closed the said shaft will assume the position shown
in Figure 1, that is to say acts to lock the pawl 7. On opening the till the shaft wo
is turned over so that the groove a enters the path of the pawl, thus allowing
of rotation of the rocking lever 3 and of the ratchet wheel 6.
The temporary locking of the rocking lever and of the number drums 12, 13
after each adjustment is effected by means of the following devices. At a suitable
point in each ratchet set (I-V) there is pivotted a pawl 23, in such a manner that
it is caused by the action of a spring 24 to have a tendency to bear against the
toothed rim of a toothed are 25 which is connected with the ratchet lever 3, but it
is prevented from so doing whilst in a position of rest, by means of a rotary
adjusting shaft 26. This shaft 26 is common to all the sets (Figure 2) and is
provided with a through recess 27 such that the latter, when the shaft 26 is
rotated allows of the entry therein of the pawl 23 of the corresponding rocking
lever 3, that is being operated at the time, and allows the said pawl to engage
with the teeth of the corresponding are 25, in such a manner that a rearward
rotation of the rocking lever 3 is prevented. The shaft 26 carries an arm 28 which
is jointed to a rod 29 that is held by a spring 30 in the position of rest .in such
a position that the shaft 26 lifts all the pawls 23 away from the corresponding
toothed arcs 25. The rod 29 thereby projects in a recess 31 of the frame. A
(Figure 1). On completely opening the till 22, a pin 32 provided on the same
enters the recess 31 of the frame A and thereby forces the rod 29 into the position
shown in Figure 2, whereby the shaft 26 is turned over so as to release the pawl 23.
The pawl 23 belonging to the ratchet set that is being operated at the time, then
engages in the adjacent toothed are 25, whereby a backward rotation of the corre-
sponding rocking lever is prevented, until on closing the till 22, the pin 32
moves out of the recess 31 and releases the rod 29, whereupon the latter is moved
back into its initial position by the spring 30. On opening the till, the rocking
lever which is then in the operative position can therefore rock back into its
initial position only after the closing of the till 22. The lid 22 is further pre-
ferably provided with a catch 33, which when the till is opened, engages with a
corresponding catch 34 of the frame A and then holds the till 22. Further the
till is also preferably provided with an alarm 35, the operating hammer 36 of
which is locked by a shoulder 37 of the till 22 when the till is closed, but when
the till is opened," is released and is caused by a spring 38 to strike against the
bell 35.
The printing apparatus is arranged upon the side of the casing A of the
apparatus, and is constructed as follows:-
The rocking lever 3 of each ratchet set carries a toothed are 39 (Figure 1)
which engages in a corresponding toothed wheel 41 mounted on a shaft 40. Each

page_text: shaft 40 carries on its end a toothed wheel 42 (Figure 9) which gears with a
toothed segment 44 mounted on a shaft 43. Each toothed wheel segment 44 is
connected with a type wheel segment 45 which as shown in Figures 9 and 11, is
provided with alternating large and small number types from 0 to 9. On the
frame A there is pivotted at 46 a support 47 which extends over all the sets I-V
and which is held under the action of springs 48 49, in the position shown in
Figure 9, and also carries a printing abutment roller 50 with rubber pad 51, and
a feeding roller 52, and is provided with a handle 53. Fixed to the support 47
at 54 is a cord 55, which passes over a pulley 57 mounted on the shaft 56. The
pulley 57 carries an arm 58 with ink pads 59 which extend over all the sets. and
which can be depressed as indicated by dotted arrows, when the support 47 is
raised by means of the handle 53 through the medium of the cord 55 on to the
types of the type wheel arc 45 that is being operated at the time, whilst when
the support 47 is released, the said pads are shot back into the position shown in
Figure 9 by means of a spring 60 (Figure 11). Around the abutment roller 50
there is led a paper strip 62 running off from the pulley 61. Through a slot 63
a price ticket or receipt form 64 can be inserted which is then pressed against the
rubber pad 51. The printing of the paper strip 62 and of the price ticket 64 is
effected first by raising the support so that the ink pads 59 are pressed down upon
the types of the type arcs 45 that are presented at the time, and then by depressing
the support 47, so that the paper strip 62 and the price ticket 64 are pressed upon
the types which are provided with ink (Figure 8). When a type wheel arc 45 is
in the position, the printing apparatus will strike upon the type 0, whereas on
operating any one rocking lever 3 the corresponding type wheel arc 45 will be
rotated to a similar extent and the type corresponding to this stroke will enter
in the path of the printing apparatus. The type wheel arcs may obviously be
provided at suitable points with types for the designations of units of value such
as for examples d, $. . The rachet mechanism for advancing the paper strip 62
is not shown in the drawings. It may obviously be made of any suitable con-
struction. In order to prevent access to the printing parts during the printing
operation and thus to prevent tampering, there are provided in the casing 47
prongs 65 which, after depression of the casing 47, project between the rims of
the type wheels and thus close the printing places towards the outside (Figure 8).
To the casing 47 there is pivotted a protective cover 66 which is capable of being
moved upon an hinge and which is intended to protect the printing apparatus
from dirt and dust.
The adding apparatus of each ratchet set I-V is provided with a ratchet or
advancing apparatus constructed as follows;--In each set the ratchet wheel 6
gears with a toothed wheel 67 which is mounted loosely on a shaft 68 that is
common to all the sets I-V (Figures 1, and 7). Each toothed wheel 67 is con-
nected with the counting disc 69 of the corresponding set which is provided with
any desired number of type numerals. In the arrangement shown in the
drawings each counting disc is provided with 20 types so that each half revolution
of a counting disc corresponds to the numbers 0-9. Each counting disc is pro-
vided on its side facing the numbering disc of the preceding ratchet set (indicating
a smaller value) with a circle of uniformly distributed pins or teeth 70. The
ratchet apparatus is now such that at every completion of a row of types of a
counting disc, that is to say, on the completion of the path from the highest num-
ber (9) to the lowest number (0), the counting disc of the next following ratchet set
(indicating a higher value) is advanced through a distance equal to the width of one
tooth, that is to say, to the extent of one type numeral. In the arrangement shown, this
operation takes place after each half revolution of each counting disc. The means
for carrying out this operation are well known and may be of any desired con-
struction. In the apparatus shown, the step by step advance of every two
co-operating sets such as for example I and II is effected by means of the levers 72
which are capable of rotating on shafts 71, and of which each is provided in the
usual manner with a pawl 74 and is drawn by a spring 75 in the direction towards

page_text: The
the axle 68 of the counting disc. Each lever 72 carries at its upper end a pin 76
which takes in a groove 77 of the corresponding counting disc 69. The pawl 74
of the lever 72 of one set, for example 1. is so arranged, that it can co-operate
with the teeth or pins 70 of the counting disc 69 of the next following set (II).
The grooves 77 of each counting disc 69 rises gradually, from the O point up to
the place corresponding to the highest number and then assumes the form of
a radially directed slot 78. In the apparatus shown, the groove 7 of the double
series of numbers of the counting discs consists of two similar branches adjoining
one another. So long as the pin 76 slides in the rising part of the groove 77,
the corresponding lever 72 is pressed outwardly so that the pawl 74 is drawn back-
wards over the pins 70 of the next counting disc. But, however, as soon as the
pin 76 enters one of the radially directed slots 78 of the corresponding numbering
disc 69 (Figure 6), the lever 72 is drawn inwards by the spring 75 whereby the
next following counting disc is moved along to the extent of one tooth.
counting disc 69 belonging to the pawl lever 72 which is operating at the time,
is also turned to 0. On further rotation of the same, the pin 76 enters again
the rising portion of the groove 77, so that the pawl lever 72 is pressed outwardly
and the pawl 74 is placed out of operation. Instead of the grooves 77 of the
counting discs 70, there may also obviously be employed cam discs or other
suitable devices. Also instead of the pawl levers 72 any other suitable means
may be employed. In the step by step advancing mechanism herein before
described it may easily happen that after the advance is effected the counting disc
that effects the advance or that one which is thrown into action, or both disc3
may be rotated further than necessary by the action of their inertia: which pro-
duces an incorrect operation of the apparatus. This drawback is obviated
according to this invention by means of the following arrangement. In each
ratchet set (IV) there is mounted so as to rotate upon a boss 79 of the lever 72
which effects the advance, a pendulum pawl 80 in such a manner that its upper
end, when in a state of rest, is situated close to the path of the pins 70 of the
counting disc which is to be advanced, but out of engagement with the said pins.
The lower part of each pendulum pawl 80 is so constructed that when the pawl
moves rapidly, the said part has a tendency to remain in its position, so that it
follows the direction of movement later than the upper part of the pendulum.
If now the lever 72 after the entrance of the pin 76 in one of the radial slots 78
of the corresponding disc 69 be drawn inwards by the spring 75, the pendulum
pawl 80 will be moved with the same; the upper part of the same entering the
path of the pins 70 of the numbering disc to be thrown into operation, and so
preventing further movement of the latter (Figure 10). The lower portion of the
pendulum pawl follows the movement only after the counting disc has been
operated. By the still continued oscillation of the lower portion of the pendulum,
the upper portion of the latter moves out of engagement with the pins of the
numbering disc to be thrown into gear, so that a further operation of the latter
is not prevented. The apparatus may however be so modified that tne pendulum
pawl 80 does not co-operate with the pins 70 of the numbering disc to be thrown
into gear, but with a separate series of ratchet teeth on the same. The action
of each pendulum pawl 80 is preferably further aided in each case by a COITE-
sponding spring 81 which is so arranged that when the counting disc to be thrown
into gear is in the stationary position, the said pawl enters with a curved part 82
between the pins 70 of the counting disc to be thrown into gear, whilst it is
pressed to one side during the advance movement by the pin which moves forward
at the time (Figure 6) and after the termination of the advance movement it enters
between the advancing and the next following pin (Figure 10) so that it offers
resistance to a further rotation of the counting disc. In order to be able to
observe the numbers marked on the counting discs, the casing 14 is provided with
observation holes 83 (Figure 1). The manipulation and mode of operation of the
apparatus are as follows; 1st. The lid 22 (Figure 1) is raised whereby the
aların 35 is sounded. After the completed stroke of the lid 22, the catch 33 of

page_text: manner.
the same engages in the corresponding catch 34 of the frame A so that the
lid 22 is firmly held. At the same time the pin 32 of the cover 22 has entered
in the recess 31 of the frame A, and the rod 29 has been moved forward and the
spindle 26 has been turned over in such a manner that its groove 27 releases
the pawls 23 (Figure 2). During the movement of the lid the rod 20 has been
drawn down by the rear shoulder 21, whereby the shaft co has been turned over in
such a manner as to bring its recess into the path of the pawls 7, and thus allow
of the rotation of the rocking lever 3 of any one set IV. When the press-knob
(for instance) corresponding to the number to be indicated, is pressed (Figure 4)
whereby the corresponding tipping shaft is turned over in such a manner as to
limit the scope of the rocking lever 3. If now the key 1 of any one set be
depressed the corresponding rocking lever 3 will be rotated as far as the shaft w7.
By means of the corresponding tooth are 9 with toothed wheel 10 the number
drums 12, 13 are carried along so that the Figure 7 is rendered visible in the
observation holes, 14 15, of the casing 16 for the purpose of being read off and
checked by the purchaser and the seller. By means of the pawl 5 of the operated
rocking lever the corresponding ratchet wheel 6 of the adding apparatus is also
moved whereby the corresponding number dise 69 is advanced to a corre-
sponding extent. After the release of the press-knob 7 the pawl 23
holds the rocking lever 3 and with it the number drums 12, 13
until the lid 22 is closed. Thus the numbers appearing in the obser-
vation holes 14 and 15 remain visible for a time so that any further alteration
in the favour of the seller of the amounts shown is prevented. After the release
of the press-knob, then any further desired set can be operated in the same
If the number 0 is to be indicated in one set, then of course, the said
set must remain in the position of rest. If in a set the number 9 is to be shown
and added up, then only the key 1 is to be depressed, because the press-knob k³
as already mentioned is "blind" and the stroke of the rocking lever 3 is then
limited by the fixed shaft w. As soon as one of the number discs 69 of any one
set passes beyond its limit the ratchet mechanism (Figures 6, 7, 10) herein-
before described acts to advance the number disc of the next following set to the
extent of one number. When the number dises of the adding apparatus are in
their limit positions, any suitable signalling or indicating device may be operated
in a suitable manner, whereupon the numbering dises can be moved by hand or
automatically in a suitable manner back into the zero position. After the operation
of the ratchet sets in any desired manner the casing 47 is raised so as to turn
the ink pads 59 (Figures S and 9) over whereby the types (which present them-
selves at the time) of the type wheel arcs 45 which are moved in the described
manner by the rotation of the rocking levers 3, are provided with ink. Then
the casing 47 for the printing apparatus 50, 51, 52, is depressed (Figure 8) whereby
the checking strip 62 and the price ticket. 64 which is to be delivered to the
purchaser are printed in accordance with the adjustment at the time. After the
release of the casing 47 which is moved by the springs 48, 49 into its normal
position the price ticket 64 can be delivered to the purchaser. After this operation
the lid 22 is again closed whereby the locking devices 23 of the rocking levers 3
are released by the return movement of the rods 29 in the manner described,
and the rocking levers 3 are returned together with the number drums 12, 13
by means of the springs 18 into the position (Figure 1), while the movement
beyond the position is prevented by the stops 19. The ratchet wheels 6 and the
number discs 69 of the adding apparatus are not moved back automatically into
their initial position, but move on continuously so that the several jamounts
indicated by the apparatus are continually added up by the adding apparatus.
Tampering with the machine cannot be effective because the operation of the
adding apparatus takes place only after the disengagement of the locking devices wº.
The arrangement in this case may be made such that the turning back of the ratchet
wheels 6 and number dises 69 can be effected only with the aid of special operating
levices, keys or the like, which are kept in the custody of the proprietor of the

page_text: business or of a confidential employee. The cash register herein described affords
the possibilty not only by uncovering the observation holes 83 (Figure 1) of ascer-
taining the total amount of the amounts paid in, but also checking the several
amounts by the sum total from the paper strip 62 after the removal of the latter
from the apparatus. It will be readily understood that the cash register herein
described may be variously modified in respect of its construction whilst retaining
the principle of the invention. For instance, instead of five ratchet sets as shown
any desired number of such sets may be employed. The lid 22 which serves to
effect the locking and unlocking of the rocking levers 3 may be replaced by
equivalent means, for example, by a handle or the like.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is:-
(1). In a cash register, an adding device provided with a ratchet wheel 6 and
devices for indicating the separate amounts paid in, said devices being operated
by means of a rotatable rocking lever 3 co-operating with the ratchet wheel 6,
in combination with means for the purpose of limiting the stroke of the rocking
lever 3 of the indicating device by the operation of a key of a suitable key board
to in the manner described and for the purpose specified.
(2). In a cash register an adding device provided with a ratchet wheel 6 and
devices for indicating the separate amounts paid in, consisting essentially of a
rocking lever 3 capable of rotating, mounted loosely on the shaft 2 of said ratchet
wheel 6, and co-operating therewith (by means of a pawl 5), and of number
drums 12, 13 operated by the said rocking lever, in combination with means for
limiting the stroke of the rocking lever in accordance with the stroke of any
desired key of a suitable key board - consisting of tipping shafts - which
when in a stationary position Figure 1, gives free passage to a locking device i
which is provided on the rocking lever and which by depressing the keys -
can be moved into a position in which it will block the path of the lever-locking
device 7 and thus prevent further rotation of the rocking lever 3, and in which
the outermost one of the tipping shafts may be made fixed so that it limits the
greatest stroke of the rocking lever 3, substantially as hereinbefore described and
for the purpose specified.
(3). In a cash register, an adding device provided with a ratchet wheel 6, and
devices operated by means of a rocking lever 3 co-operating with the ratchet
wheel 6, for indicating the separate amounts paid in, in combination with a lid
22 of a money till, and with means for preventing a rotation of the rocking lever 3
when the lid 22 is closed and for allowing such rotation only when the lid is opened,
substantially as described and shown.
(4). In a cash register, an adding device provided with a ratchet wheel 6 and
devices for indicating the separate amounts paid in, operated by means of a rocking
lever 3 co-operating with the ratchet wheel 6 in combination with the lid 22 of a
money till which when it is in its closed position acts by means of suitable
mechanism 20, 21, to hold a tipping shaft we provided with a recess 7° in such a
position that it blocks the path of a pawl 7 attached to the rocking lever 3 and
thereby prevents the rocking lever 3 from rotating out of the position, whilst
when the lid 22 is opened the tipping shaft is rotated in such a manner as to
allow the pawl 7 to pass through its recess ", substantially as hereinbefore described
and for the purpose specified.
(5). In a cash register, an adding device provided with a ratchet wheel 6 and
devices for indicating the separate amounts paid in, operated by means of a
rocking lever 3 co-operating with the ratchet wheel 6, in combination with means
for the purpose of effecting a temporary locking of the backward rotation of the
rocking lever 3, in the actuation of said rocking lever, substantially as herein before
described and for the purpose specified.
(6). In a cash register, an adding device provided with a ratchet wheel 6 and

page_text: devices for indicating the separate amounts paid in, operated by means of a rocking
lever 3 co-operating with the ratchet wheel 6, in combination with the lid 22 of a
money till and with locking devices, 23 for the rocking lever 3 which, when the
lid 22 is closed, are raised by a tipping shaft 26 with groove 27 away from the
rocking lever 3,. whilst when the lid 22 is opened, the said locking devices are
freed by suitable mechanism 28, 29, 32 (which cause a rotation of the tipping
shaft 20) by means of the groove 27 of the tipping shaft 26, so that said locking
devices will, when the rocking lever 3 is operated, cause a locking of the same
against rearward rotation, which locking ceases only when the lid 22 is closed,
substantially as herein before described and for the purpose specified..
(7). In a cash register, an adding device, and devices co-operating therewith
for indicating the separate amounts paid in, in combination with means for
enabling the separate amounts indicated by the apparatus to be printed upon a
continuously travelling paper strip 62 and also if desired upon a separate receipt
form 64, consisting of type wheel arcs 45 to which there is imparted by the
operation of the indicating device by means of suitable mechanism 39, 40, 41, 42
the same rotary motion as imparted to the indicating device, also further, of a
suitable printing apparatus (47, 50 51 52 59 61) which receives the paper strip 62
and also if required the ticket 64, and which can be pressed down upon the type
wheel arcs, 45, substantially as hereinbefore described and for the purpose
specified.
'
(8). In a cash register, an adding device provided with any desired number of
counting discs 69 and driven by means of a ratchet wheel 6, and devices for
indicating the separate amounts paid in, operated by means of a rocking lever 3
