  • the devices according to the present invention are also designed to be programmed in such a way that the program thereby obtained is not permanent, but can easily be changed, if required.
  • the present invention has kept hold of this and refers to a device for performing functions in a business machine, such as in a cash register, whereby without modification of the construction of the machine, a very great number of programs can be obtained. Additionally, these programs can easily be changed by exchanging special program means, whereby the machine will receive another pattern of operation in order to perform the functions.

  • the programmed means according to the present invention consist of cams, arranged on the operation means, or on means being controlled by these means which can select and/or control the totalizers which are arranged in the machine. Influenced by one or more of these operating means which consist of selector keys, function keys and a zeroizing-reading slide in the embodiment described below, attached cams will extort that a number of coupling means (coupling plates) will obtain a position wherein they are able to indirectly control and select totalizers. These coupling means are not programmable by themselves but constitute a unit, which can be affected by all of the operating means. Thus, each coupling means will, when activated, indirectly control and/or select a setting of a certain totalizer at a certain time during the machine cycle.
  • Each cam constituting one of the programmable means, is provided with a number of teeth maximally corresponding to the number of coupling means.

  • cams in the cash register have the same configuration, except for the positioning and number of the teeth, and therefore the retail dealer needs to store only one type of re-programmable means.
  • the devices according to the present invention also include means which are able, in a machine cycle, to control a totalizer shaft laterally in order to perform zeroizing in one of its totalizers during a first part of the machine cycle and in order to perform accumulation in another of its totalizers during a second part of the machine cycle.
  • These means consist of a number of the above described coupling means which are affected by the cams on the operating means, whereby two different groups of coupling means control the mentioned totalizer before zeroizings respectively accumulation operation.
  • the two groups of coupling means are arranged to be sensed by a sensing device, which controls the totalizer shaft laterally and before zeroizing operations senses the adjusting of one group of the coupling means and before the accumulating operations senses the adjusting of the second group of coupling means.
  • a testing device which, at least at one point of time during the machine cycle, senses all the settings of totalizer shafts and brings the totalizer shaft (s), the totalizer (s) of which must not be in engagement with the actuators during their movement, away from the actuators.

  • itemizer 8 has only been briefly described above. Equally, the 10s transfer means has not been shown or described in detail. However, when an itemizer of the credit-balance type and corresponding tens transfer means do not constitute a condition for realization of the invention, such as has been expressioned in the claims, and as these means furthermore are well known to the man skilled in art, see for example US. Pat. No. 3,244,367, the specification above ought to be satisfactory.

  • the two banks positioned beside the bank positioned to the very right in FIGS. 1a and lb contain department keys 44. It is to be realized that the number of keys in each bank can be varied depending on the way of working of the machine and each bank can maximally contain nine keys. To the left of the three described banks are seven banks of amount keys (not shown) which are well known to the man skilled in art and will not require any specification.
  • Each key 38, 40, 42 in the bank positioned to the very right in FIG. lb, below referred to as the first bank, is provided with a key shaft 380, 40a, 424, on the lower part of which a cam holder 46 of plastic is arranged (see FIG. 3b).

  • In the first bank seven slides 51 have been shown.
  • Group slides 500, b and c rest with their bottom edges on a lower keyboard plate 56, which is fixed to the machine, and in their upper edges they are provided with recesses in which protrusions 44b of key shafts 444 can be positioned.
  • the recesses in slides 50 can be of two kinds and therewith exhibit different functions.
  • Recesses 50b and 50c are shaped with a part that inclines towards the ground plane, which part will be affected by a key positioned above the same when this key is depressed, whereby group slide 50b or 50c receives a longitudinal movement to the right in FIG. 3a.
  • Recesses 50b" have such a large horizontal extension that it is impossible for the key positioned above this recess to move slide 50b.
  • Recesses similar to recesses 50" can also be provided in slides 50a and 50c.
  • Keys 44 in the two selector banks are divided into classes, which means that they are able to control totalizer shaft 2 to difi'erent positions at different points of time during a machine cycle. Keys 44 of the same class in a selector bank thus work on the same group slide. Keys of different classes in the same selector bank work on different group slides such as on group slides 50a and 50b in the third bank, in doing which a recess which is not provided with an inclining part, such as recess 50b", on a group slide, such as group rack 50b, is positioned immediately under a key 44, which is intended to affect another group rack in the same bank. In its to the very left in FIG.
  • every group slide 50b, 50c in its lower edge is provided with a protrusion 50b", 50c" which when the respective group slide moves obliquely upwards to the right in FIG. 3a, via a key 44, affects a group link 58b, 58 c, supported for turning movements, in dovetail-shaped groves 60a in two bearing plates 60 being fixed to the machine.
  • Each group like 58 is on the end which is positioned at the opposite end of the group slides provided with a cam holder 62 of the same construction and material as the cam holder 46, which is pushed on the key shafts 38a, 40a, 42a. Also the cam which is positioned in the cam holder 62 is of the same material and construction as the cam 48.
  • cam 64a of cam 64 extend out of the cam holder 62 and their number and position is depending on the operation program determined for the machine.
  • Cam holder 62 can with a simple movement of ones hand be removed from group link 58 and cam 64 can be replaced against another cam with another number of teeth, for reasons which appear from the following.
  • a zeroizing and reading slide 66 is arranged for horizontal movement.
  • one end slide 66 has an upwards extending arm 660 on which there is a button 66b, accessible on the keyboard of the machine.
  • a gear track 66c which is in constant mesh with a toothed wheel 68 attached to a rotatable means, below mentioned whirligig 70.
  • Whirligig 70 which is rotatable on a shaft 74 attached to the frame 72 of the machine is provided with eleven lateral slots 70a in which earns 76 are arranged.
  • Cams 76 which are of the same construction and material as earns 46 and 64 and are provided with teeth 760, can with a simple movement of ones hand be pulled out of slots 70a and can be exchanged against other cams, that thereafter can be put back into the recesses 700 just as easily.
  • Slide 66 which is movable upwards downwards in FIG. lb can take up the same number of positions as whirligig 70 has slots 70a and cams 76, i.e. eleven positions.
  • whirligig 70 is rotated counter clockwise, in FIG. 3a, to a so caIled reading position and when slide 66 is moved upwards whirligig is rotated clockwise in FIG. 3a to a so called zeroizing position.
  • slide 66 can take in one register position, five reading positions and five zeroizing positions.
  • Keys 38, 40, 42 with their earns 46, keys 44 with their cams 64, and whirligig 70, with its cams 76 are arranged to be able to affect I4 coupling plates 78 104 (see FIGS. lb and 2a and 2b) which are arranged for movement upwards downwards (FIGS. 20 and 2b by recesses 78a-104a, which surround shafts 106, 108 fixed in the frame 72 of the machine and the plate 110. All coupling plates 78 104 receive a movement upwards (FIGS. 20 and 2b) by tension springs (one is shown in FIG.
  • Coupling plates 78-104 can thus be prevented from moving upwards partly by teeth 480 on a depressed key 38, 40, 42 in the first bank, whereby the upper parts of coupling plates 78-104 are in direct contact with teeth 48a, partly by teeth 64a on a group link 58, which, receives a motion of rotation by belonging key 44 when depressed, so that teeth 64a which are normally positioned above recesses 78e-104e in coupling plates 78-104, take up a position directly above the remaining sections between recesses 78e-104e on coupling plates 78-104, in doing which the remaining sections between the recesses make contact with teeth 64a, partly by teeth 76a on the Whirligig, which has been set by zeroizing reading slide 66, whereby recesses 78c-104c make contact with teeth 76a.
  • Each of cams 46, 64 and 76 can be provided with maximally 14 teeth 46a, 64a, 76a. In case that all fourteen teeth are positioned on a depressed key 38, 40, 42 or 44, or on that cam 76 on Whirligig 70, which has been set directly above recesses 78c-104c none of coupling plates 78-104 can be raised. In order to make it possible for some of coupling plates 78-104 to be raised after the pawl 118 has been released, one or more teeth 46a, 64a, 76a on a depressed key or on the set Whirligig 70 must be removed.
  • the task of coupling plates 78-104 is partly to control the totalizer shafts 2, 4 and 6 to and out of engagement with the differential actuators i.e. the racks, partly control the lateral movement of totalizer shaft 2 at different points of time.
  • Each of coupling plates 78, 80, 82 controls a totalizer shaft at zeroizing operations
  • each of coupling plates 84, 86, 88 controls a totalizer shaft 2, 4, 6 at registering operations, such as addition, coupling plates 90, 92, 94, 96 control totalizer shaft 2 immediately before the racks being their zeroizing movement, whereat coupling plate 90 controls totalizer shaft 2 sideways so that it takes up a position where wheel 8b of itemizer 8 is in a position immediately below the racks.
  • Coupling plate 92 controls shaft 2 laterally so that the wheels of its totalizer 12 are positioned immediately below the racks.
  • Coupling plate 94 controls shaft 2 laterally so that the wheels of its totalizer are positioned immediately below the racks.
  • Coupling plate 96 controls shaft 2 laterally so that addition wheels 80 of itemizer 8 are positioned immediately below the racks.
  • Coupling plates 98-104 control totalizer shaft 2 immediately after that the racks have finished their zeroizing movement but before the racks have begun their returning movement, i.e. addition movement.

  • Coupling slide 136 receives a longitudinal reciprocal movement during each machine cycle via a coupling arm 138 which is supported on the coupling slide and a curve 140 on the machine's main shaft 116 which curve affects coupling arm 138.
  • Coupling arm 138 is rotatably supported on shaft 198 which is fixed to the machine.

  • crank 158 is carried off to crank 164 via transfer link 160, while each of cranks 180, 182 directly affects one shaft corresponding to shaft 166.
  • This carrying off has been made because of the determined positioning of totalizer shaft 2, with itemizer and totalizer, outside, i.e. in FIG. 3a in front of coupling plates 78-104. It is viz. of practical reasons not possible to arrange coupling links in front of coupling plates 78-104 with simple means. In case that the machine is to be equipped with an itemizer that cannot be moved laterally, it is possible to connect it directly to shaft 1580 of coupling crank 158. Transferring link 160, and totalizer shaft 2 with belonging devices are therefore unnecessary.

  • links 130 and 134 of coupling plates 84 and 88 have been moved upwards it will be possible to move these forward because the recesses 130a and 1340 have such a long vertical extension that it exceeds the vertical distance of movement of each coupling plate.
  • coupling links 130, 134 When coupling links 130, 134 are moved forward they bring, via the hook-shaped parts 130b, 134b, shafts 154, 156 in the forward movement as these shafts are positioned in the path of movement for parts 130b, 134b, while coupling link 132 does not bring shaft 152 due to the fact that, in the present example, this is positioned above the path of movement of hookshaped part 132b.
  • shafts 154, 156 When shafts 154, 156 according to the preceding example receive a forward movement cranks 158, 180 are turned, and belonging counter shafts 2 and 6 are thereby raised to engagement with the racks in order to allow these to perfonn accumulation in the raised totallzers.

This lateral movement is described in U.S. Pat. No. 3,263,915 to which reference is made for a detailed specification. Totalizer shaft 2 is also moved sideways, if necessary, by below described means. Afler totalizer shafts 2, 4 and 6 have taken up their determined positions only the totalizer shafts whose coupling shafts 152, 154, 156 have been activated by coupling links 124, 126, 128 at the forward movement of the coupling slide 146 are raised to the racks.
  • the restoring means shown in FIG. 4 includes curves 194, 196 positioned beside each other and fixed on main shaft 116.
  • An arm 200, rotatably supported in fixed shaft 198 cooperates, via a projecting part 200a, with curve 194 and via another projecting part 20% with curve 196.
  • Arm 200 is supported in a drive bar 202 which in its turn is displacably supported in fixed shaft 192.
  • On its upper side bar 202 is provided with three circular protrusions 2020 on which test arms 204, 206, 208 are rotatably supported.
  • Test arms 204, 206, 208 are via leaf springs 210, 212, 214 forced upwards in FIG. 4, which visualizes the rotation of main shaft 116 after 10, and contacts the lower side of protrusions 72a, 72b,72c on frame 72.
  • test arms 204, 206, 208 will restore the totalizer shafts whose totalizer wheels must not be in engagement with the racks during the zeroizing movement, from the intennediate position to the lower position.
  • This restoring takes place between 87 and 98 rotation of main shaft 116, Le. before the racks have begun to move which happens at l l0.
  • FIG. 5 is visualized as example a machine operation where totalizer shaft 2 is about to be raised to engagement with the racks during the restorement of totalizer shafts 4 and 6 to the lower position.
  • This example must not be mixed up with the example shown in FIGS. 1-3 where it is quite apparent that no totalizer shafts 2, 4, 6 are in engagement with the racks during a zeroizing operation.
  • Coupling crank 158 which belongs to totalizer shaft 2 has, as is apparent from FIG. 5, received a clockwise movement while coupling cranks 180, 182 which belong to totalizer shafts 4 and 6 have not been rotated at all from their intermediate positions.
  • coupling cranks 182, 158, 180 are in the angular position visualized in FIG. 4.
  • main shaft 1 16 is rotated to the position shown in FIG. bar 202 will receive a motion to the right by the high periphery 1940 of earn 194, whereby the upper edges of test arms 204 and 208 move away from protrusions 72a and 72c and spring upwards to a position between corresponding protrusions and a hook 182b, 180b on crank 182, 180.
  • test arm 206 When the bar is moved to the right, the upper edge of test arm 206 will also move away from protrusion 7212 but will not spring upwards and take up a position between protrusion 72b and hook 158b, depending on the fact that crank 158 is moved so far clockwise that the distance between protrusion 72b and hook 158! is less than the horizontal extension of the upper edge of test arm 206. Thus, when bar 202 is moved to the right the upper edge of test arm 206 will take up a position below crank 158, as shown in FIG. 5.
  • test arms 204, 208 will push on the vertical parts positioned at the very left of hooks 180b, 182k and thereby restore coupling cranks 180, 182, and therewith totalizer shafts 4 and 6 to the position shown in FIG. 4.
  • test arm 206 will with its upper edge slide on the lower part of hook 158b, whereby the setting of coupling crank 158, and thereby the setting of coupling shaft 2 will not change.
  • Bar 202 will be restored to its position at the very left in FIGS. 4 and 5 by path 196a and curve 196 when main shaft 116 has rotated between 171,5 and 198.
  • test arms 204, 206, 208 are forced back over protrusions 72a, b, c to the position shown in FIG. 4.
  • the totalizer shaft 2, 4 or 6 which was in engagernent with the racks during the zeroizing operation is moved down to the intermediate position in order to allow totalizer shaft 2 to be moved sideways, if desired.
  • the restoring to the intermediate position is performed by a curve 216 on main shaft 116.
  • Curve 216 is shown in FIG. 7 after 10 rotation of main shaft 116. After main shaft 116 has been rotated 178 path 2160 on curve 216 will contact an arm 218, rotatably supported in shaft 198, whereby arm 218 receives a clockwise motion and displaces slide 220 which is supported in arm 218 to the right in the figure.
  • Totalizer shaft 2 according to the above described example having been in engagement with the racks during their zeroizing movement will be restored from the dashed position in FIG. 5 to the dashed position in FIG. 7 by protrusions 220a on slide 220, via corresponding coupling crank 158 and its shaft 154.
  • main shaft 116 has been rotated 185 the restoring of totalizer shaft 2 to the intermediate position has been finished.
  • path 216e will contact arm 218, whereby shafts 152, 154, 156 of coupling cranks 182, 158, 180 are not affected by protrusions 2200.
  • totalizer shafts 2, 4, 6, in whose totalizer wheels accumulation is to be performed will be raised to engagement with the racks.
  • the totalizer shafts in the above example totalizer shaft 4 which during the zeroizing movement were not in mesh with the racks, i.e. were positioned in their lower positions, by path 190b of curve 190, arm 186, slide 184, protrusions 1840 etc. (FIG. 6) have been raised to the intermediate position.
  • totalizer shafts 2, 4, 6 The raising of totalizer shafts 2, 4, 6 from the intermediate position to be in mesh with the racks immediately before these begin their accumulation movement is performed by coupling plates 84, 86, 88, coupling links 130, 132, 134, coupling slide 136, arm 138, curve 140, shafts 152, 154, 156 etc. in a way described above in connection with FIGS. l-3. 1n the example according to FIGS. 1-3 totalizer shafts 2 and 6 are raised towards the racks. Totalizer shaft 4, in which, according to the example, accumulation is not to be performed, is restored from the intermediate position to the lower position in the same way as described above, viz. by the devices according to FIGS.
  • each totalizer shaft 2, 4, 6 will be moved to the lower position, i.e. to engagement with the tens transfer means.
  • FIG. 7 shows that curve 216 with its path 216a at the end of the machine cycle affects arm 218, which in turn affects slide 220 to be moved to its end position to the right in the figure, whereby protrusions 2200 of slide 220 contact shafts 152, 154, 156.
  • coupling cranks 182, 158, are positioned in their counter clockwise position whereby totalizer shafts 2, 4, 6 are in their lower positions.
  • Slide 220 is provided with an angle-shaped arm 22% (also see FIG. 3a), which affects coupling links 126 and 132 to pivot counter clockwise when slide 220 is moved to the right in FIG. 7.
  • slides 146 and 136 will move to the right in FIGS. 30 and 3b whereby also coupling links 124, 128, 130, 134 will pivot counter clockwise.
  • arm 220 receives its movement to the right at the end of the machine cycle (at a rotation of 258 of main shaft 116) each of coupling links 124-134 will be restored before a new machine cycle begins.
  • slide 184 cannot be restored by its arm 218 and curve 216.
  • curve 190 will restore shafts 152, 154, 156 to the left after curve 216 has performed its movement and affected shafts 152, 154, 156.
  • Curve 216 will restore shafts 152, 154, 156 to the right alter curve 190 has performed its movement and affected shafts 152, 154, 156. It becomes more apparent by FIG. 9 how the described cooperation between curves 190 and 216 is performed in the span of a machine cycle.
  • FIGS. la, lb, 2a, 2b, 8 and 9 how totalizer shaft 2 is selected laterally once before the zeroizing operation once before the accumulation operation.
  • coupling plates 90-104 which control the lateral movement of totalizer shaft 2.
  • Coupling plates 90-104 strive to move upwards in the same manner as coupling plates 78-88, whereby certain plates are allowed to be raised since teeth 48a, 64a, 760 on cams 48, 64, 76 are not positioned in the path of movement of these plates.
  • coupling plates 90-96 control the lateral movement of totalizer shaft 2 immediately before the racks begin the accumulation movement.
  • Each coupling plate 90-96 is provided with a protuberance 98d-l04d in the form of a shelf, positioned a bit further backwards on the coupling plate in the machine than protuberance 90d-96d on coupling plate 90-96.
  • a differential means is arranged to sense protuberances 90d-l04d on coupling plates 90-104 in a way that it immediately before the zeroizing movement of the racks senses the setting of coupling plates 98-104 and immediately before the accumulation movement of the racks senses the setting of coupling plates 98-104.
  • Differential means 222 consists of two racks 224 and 226, which receive movement via one drive arm 228, for each rack 230, which are meshed with recesses 224e, 226a, in the racks.
  • Racks 224, 226 are supported in a support plate 232, via rivets 234 and 236, and will move in relation to this only from the right to the left and conversely in FIG. lb.
  • Rack drive arms 228, 230 are in their, from the racks 224, 226 turned ends rotatably supported on a joint shaft 238, which is attached to a support 240, fixed in the machine.
  • a projecting part 242a on a drive arm 242 is arranged to run vertically in FIGS. 2a and 2b.
  • Drive arm 242 is provided with two rollers 244 and 246 which run on curves 248, 250 affixed to the main shaft 116 of the machine.
  • Curves 248, 250 have such a shape that drive arm 242 receives an upwards and downwards, vertical movement before the zeroizing movement and an identical movement before the accumulation operation (see FIG. 9).
  • Each of racks 224, 226 is provided with two protrusions in the form of brackets 2240, 224b, and 226a, 226b.
  • Brackets 224a and 226a are intended to affect protuberances 90d-96d while brackets 224b and 22612 are intended to affect protuberances 98d-l04d.
  • support plate 232 and therewith differential means 222 are vertically movable in FIG. 1b.
  • Drive arm 252 which meshes with a cutout 232a in support plate 232.
  • Drive arm 252 as well as rivets 234, 236, does not prevent the horizontal movement of racks 224, 226 in FIG. 1b.
  • Drive arm 252 receives a reciprocal movement from curves 254, 256 which are directly cooperating with the same and attached to main shaft 116.
  • Drive arm 252 is, approximately in the middle, rotatably supported in an arm 258 which is attached to frame 72.
  • Support plate 232 is supported in plate 1 10 and frame 72 for its movement.
  • FIGS. 2a and 8 is explicitly shown how coupling plates 96 and 104 at the beginning of a machine cycle have been able to obtain a raised upper position which means that totalizer wheel of itemizer 8 is in a position immediately below the racks before the zeroizing operation. This is also the case before the accumulation operation. In other words according to the example shown in the figures a reading operation in the itemizer will be carried out, which means that this must not be laterally moved during the machine cycle. However, it is not necessary for a reading operation to be carried out in the itemizer. As will be understood from the specification above, only coupling plates 78-88 control the totalizers upwards towards the racks while coupling plates -104 only control the totalizer shaft laterally. One of coupling plates 90-104, for example coupling plate 96 in FIG. 8, can thus be raised and totalizer shaft 2 moved laterally without requiring this shaft to be brought into engagement with the racks.
  • drive arm 252 receives a pivoting movement around shaft 258 whereby support plate 232 and therewith differential means 222 receives a position downwards in FIG. 1b.
  • racks 224, 226 thereafter receive a movement towards each other, from the position shown in FIG. 1b, protuberance 96d is in the path of movement for bracket 2240 (whose movement will occur obliquely downwards to the right in FIG. 8) and moves bracket 226a (whose movement occurs obliquely upwards to the left in FIG. 8).
  • Bracket 224a will thereby be moved a distance from the position shown in FIG. 8 while bracket 2260 will not be appreciably moved.
  • bracket 224a Since bracket 224a is allowed to be moved, rack 224 whose projecting part 224:! is moved to the right in FIG. lb or 2a so far that an arm 2a attached on totalizer shaft 2 will be affected by part 224d and move to the right, until the side which is turned away from part 224 makes contact with one projecting part 226d on rack 226.
  • arm 20 When arm 20 is moved to the right, which is decided by the raising of coupling plate 96, totalizer shaft 2, which is supported in totalizer frames 176, 178 for lateral movement, receives a movement to the right in FIG. la or 2a, whereby its totalizer wheel 8a is positioned immediately below the actuator racks.
  • brackets 224b and 226b In order not to allow the vertical parts of brackets 224b and 226b (see FIG. 8) to contact any of coupling plates 90-104 immediately before the zeroizing operation, i.e. when brackets 224a and 2260 cooperate with protuberances 90d-96a', these will be moved towards each other directly in front of (FIG. 8) protuberances 98d-l04d and directly behind protuberances 9011-964, which means that there is a distance (vertically in FIG. lb), at least as large as the thickness of the vertical part of each bracket, between the back edge of a protuberance 90d-96d and the front edge of a protuberance 98d-l04d.
  • racks 224 and 226 receive a movement from each other by earlier described means, and support plate 232 with racks 224 and 226 receive a movement upwards in FIG. lb by earlier described means.
  • the lateral position of totalizer shaft 2 during the accumulation operation is thereafter selected in that the brackets 224! and 226b which are moved away from each other are moved towards each other and sense protuberances 98d-l04d (see FIG. 8).
  • brackets 224a and 2260 will be moved towards each other but will not be able to contact any protuberance 904-10411 because they run in front of protuberances 98d-104d and behind protuberances 90d-96d, in the same way as with the brackets 2241: and 226b immediately before the zeroizing operation.
  • bracket 226b cannot be moved to the left since protuberance 104d is in its path of movement.
  • Bracket 22Ab on the other hand will be moved to the right and contact protuberance 104d.
  • totalizer shaft 2 during zeroizing operation was in the position at the very right in FIGS.
  • FIG. 3b is shown how the setting of the coupling plates control the zero-stops of the cash register.
  • zero-stops 260, 262 have been shown, the purpose of which is to affect the differential actuators (the racks) which are positioned below the lower key board plate 56 in two amount orders in order to keep the actuators in zero position during accumulation operations when no key has been depressed in the amount banks positioned above these actuators.
  • the number of zero-stops is equal to the number of orders in the machine but for the sake of clearness only two are shown in FIG. 3b.
  • Zero-stops 260, 262 extend through recesses in the lower key board plate 56, as well as in a support bridge 263, which is attached to the lower key board plate, and are drawn downwards in FIG.
  • Bracket 268 is supported for rotatory movement, such as at 270, and is provided with a downwards directed arm 268c with recess 268d.
  • An angular arm 272 rotatably, supported in a rivet 274 which is attached to the lower key board plate 56, cooperates with recess 268d.
  • Angular arm 272 is at its from the recess 268d turned end, via a rivet 276 rotatably supported in a test arm 278 which has a downwards directed part 2780 the task of which is to sense the vertical adjustment of coupling plates 78, 80, 82 via a recess in the lower key board plate.
  • tongue 268b is afi'ected by an arm 280a on a bracket 280, which is rotatably supported in 282 and 284.
  • bracket 280 On bracket 280 is attached a roller 286 which is affected by a lifting arm 28 supported for vertical, reciprocal movement on rivet 290.
  • lifting am 288 In the end which is turned away from roller 286 lifting am 288 is supported in a cam follower 292, by rivet 294.
  • Cam follower 292 is rotatably supported on rivet 296 and is provided with a roller 298 cooperating with a disc 300 attached to a shaft 302 which is driven by the machine.
  • Disc 300 when rotated, affects bracket 280, via follower 292, and arm 288.
  • Disc 300 receives a counter clockwise rotation during a machine cycle whereby arm 280a first receives a downwards movement so that tongue 268b and thereby bracket 268 will be released for downwards movement provided that coupling plates 78, 80, 82 take up the not raised position shown in FIGS. 3a and 3b.
  • springs 264, 266 will pull zero-stops 260, 262 to engagement with the racks, if a key in the corresponding bank is not depressed, whereby the racks cannot be removed.
  • bracket 268 cannot be rotated counter clockwise due to a vertical protrusion 78f, 80f or 82f being positioned in the path of movement of test arm 278.
  • arm 268 strives, influenced by springs 264, 266, to be rotated counter clockwise in order to rotate arm 272 counter clockwise.
  • Arm 272 strives to give test arm 278 a longitudinal movement obliquely downwards to the left in FIG. 3b.
  • bracket 268 cannot be rotated counter clockwise to allow the downwards directed movement of zero-stops 260, 262.
  • the reason for not allowing zero-stops 260, 262 in the amount banks to be in their lower position when some of coupling plates 78, 80 or 82 is in its upper position is that at zeroizing or reading operations, which is represented by at raising of some of the mentioned coupling plates, the racks can be moved to positions which are represented by the setting of the totalizer wheels without being prevented by any key or any ze rostop.
  • Each selector bank is also provided with a zero-stop.
  • This zero-stop 304 is schematically shown in FIG. 3b.
  • the movement of the zero-stops in the selector banks is not dependent of the setting of the coupling plates and is therefore controlled only by disc 300, follower 292, lifting arm 288 and bracket 280.
  • the operator first depresses one or more of the amount keys (not shown) whereafter the department key 44 marked with M is depressed.
  • Key M when depressed causes the machine to start (group slide 50d affects a starting device) and group slide 50b rocks the group link 58b backwards in the machine, whereby cam 64 is positioned immediate- 1y above recesses 78e-l04e positioned between two protrusions on coupling plates 78-104.
  • Coupling plates 78, 80, 86, 90, 92, 94, 98, 100 and 102 are stopped by remaining teeth 64a on cam 64, and coupling plates 80 and 82 are stopped by remaining teeth 76a on cam 76, and consequently only coupling plates 84, 88, 96 and 104 receive an upwards movement.
  • Coupling plates 84 and 88 control as described in detail above, coupling of totalizer shaft 2 and 4 with the racks during the accumulation operation and coupling plates 96 and 104 control the lateral position of totalizer shaft 2 during the zeroizing operation and during the accumulation operation, respectively.
  • totalizer shafts 2, 4 and 6 are again raised to the intermediate position by the devices shown in FIG. 6, and the devices shown in FIG. 7 restore the totalizer shafts (none in the present example) which had been in engagement with the racks during the zeroizing operation to the intermediate position.
  • Racks 224, 226, which earlier during the machine cycle have moved away from each other, again receive a movement towards each other, and their brackets 224b, 226b squeeze around protuberance 104d.
  • totalizer shaft 2 will not be moved laterally, as it already prior to the zeroizing operation had obtained a position which is represented by coupling plate 96 as well as coupling plate 104.
  • Support plate 232 together with racks 224, 226 receive a movement upwards in FIG. lb before the beginning of the last mentioned movement.
  • coupling slide 136 receives a longitudinal movement by curve 140 and brings along coupling links 130, 134 which had been raised by coupling slides 84 and 88 whereby these links in turn bring along their shafts 156 and 154, 162 causing totalizer shafts 2 and 6 to raise towards the racks.
  • the devices in FIGS. 4 and 5 restore totalizer shaft 4 to its lower position, whereafter the racks perform accumulation in one of the totalizers of totalizer shafts 2 and 6, i.e. in totalizer 8 and in the totalizer selected by key M.
  • totalizer shafts 2 and 6 are moved to their lower positions i.e. in engagement with the tens transfer means, by the devices according to FIG. 7.
  • the machine cycle is thereafter finished by restoring certain of the above described devices to the home position, such as restoring coupling plates 84, 88, 96 and 104, (by hook 118), while certain other of above described devices are restored in the first part of the following machine cycle.
