Zur zahlenmäßigen Anzeige von Meßwerten ist es bekannt, ein mehrstelliges Zählwerk.zu benutzen, dessen zuäußerst rechts befindliche Ziffernrolle unmittelbar von einem Meßwertgeber, wie etwa einem Schrittmotor od. dgl., angetrieben wird. Jede weitere Ziffernrolle des Zählwerkes wird von der rechts von ihr befindlichen Ziffernrolle aus vermittels einer Zehnerübertragung fortgeschaltet. Dabei sind die Ziffernrollen des Zählwerkes meistens gleichachsig und in der Zeilenrichtung nebeneinander angeordnet, so daß der von den Ziffernrollen abzulesende Meßwert in der Form einer dezimalen Zahl erscheint. Für besondere Zwecke hat man jedoch auch schon Zählwerke gebaut, deren Ziffernrollen sich zwar ebenfalls in der Zeilenrichtung der abzulesenden Zahl nebeneinander befinden, jedoch auf einzelnen Zählwerkwellen befestigt sind, die sich senkrecht zur genannten Zeilenrichtung erstrecken. Die Zehnerübertragungen sind bei dieser Bauart des Zählwerkes zwischen den zueinander parallelen Zählwerkwellen wirksam und weisen gezahnte Zwischenachsen auf.For numerical display of measured values, it is known to use a multi-digit counter, whose rightmost digit roller directly from a transducer, such as a Stepper motor or the like. Is driven. Each additional number roll of the counter is taken from the one to the right of her located digit roll advanced by means of a tens transmission. There are the number roles of the counter mostly coaxially and arranged side by side in the row direction, see above that the measured value to be read from the number rolls appears in the form of a decimal number. For special For this purpose, however, counters have also been built, whose number rolls are also different are next to each other in the line direction of the number to be read, but on individual counter shafts are attached, which extend perpendicular to said row direction. The tens transfers are effective with this type of counter between the parallel counter shafts and have toothed intermediate axles.

Es ist nun oft die Aufgabe gestellt, einen in einem bestimmten Zeitmoment vorhandenen Meßwert speichern zu können, ohne zu diesem Zweck das Zählv^-werk anzuhalten. Eine bekannte Lösung dieser Aufbe sieht hierzu ein zusätzliches Speicherzählwerk vor, das synchron mit dem dauernd laufenden Hauptzählwerk vom Meßwertgeber angetrieben wird, jedoch vom letzteren abschaltbar ist, so daß der im Moment seiner Abschaltung vorhandene Meßwert durch das Speicherzählwerk festgehalten wird. Bevor dann aber das Speicherzählwerk wieder an den Meßwertgeber angekuppelt werden kann, ist es so weit nachzustellen, bis seine Anzeige wieder genau mit derjenigen des inzwischen weitergelaufenen Hauptzählwerkes übereinstimmt, denn dies ist die Voraussetzung für eine weitere Speicherung zu einem späteren Zeitmoment. Muß dieses Nachstellen des Speicherzählwerkes von Hand erfolgen, so ist dies oft ein umständlicher und auch zeitraubender Vorgang, der als unerwünscht angesehen wird. Anderseits sind automatische Nachstellvorrichtungen mit Hilfe von Nachlaufsteuerungen sehr aufwendige Zusatzgeräte, deren Anwendung zum Nachstellen eines Speicherzählwerkes in der Regel kaum gerechtfertigt erscheint. Eine weitere ebenfalls bekannte Lösung der erwähnten Aufgabe besteht in der Verwendung eines zusätzlichen Druckers, dessen Typenräder synchron und dauernd von den ihnen zugeordneten Ziffernrollen des vom Meßwertgeber angetriebenen Zählwerkes aus nachgeführt werden. Die Speicherung eines Meßwertes erfolgt dann durch Abdrucken derIt is now often the task of being able to store a present in a given moment of time measurement without stopping for this purpose, the count v ^ -Werk. A known solution to this Aufbe provides an additional memory counter which is driven synchronously with the continuously running main counter by the transducer, but can be switched off by the latter so that the measured value present at the moment of its switch-off is recorded by the memory counter. But before the memory counter can be coupled to the transducer again, it must be readjusted until its display again exactly matches that of the main counter, which has continued to run in the meantime, because this is the prerequisite for further storage at a later time. If this readjustment of the memory counter has to be carried out by hand, this is often a cumbersome and time-consuming process which is viewed as undesirable. On the other hand, automatic readjusting devices with the aid of follow-up controls are very complex additional devices, the use of which for readjusting a memory counter generally hardly appears to be justified. Another also known solution to the above-mentioned problem consists in the use of an additional printer, the type wheels of which are tracked synchronously and continuously by the number rollers assigned to them of the counter driven by the transducer. A measured value is then stored by printing the

Ein derart betriebener Drucker ist indessen ebenfalls ein vergleichsweise kostspieliges Zusatzgerät.The position of the type wheels at the moment in question. A printer operated in this way is however, it is also a comparatively expensive additional device.

Die vorliegende Erfindung befaßt sich demgemäß mit einer Einrichtung zum Festhalten von Zählerstellungen während eines Zählvorganges mit einem vom Meßwertgeber angetriebenen mehrstelligen Zählwerk, dessen Ziffernrollen in der Zeilenrichtung der anzuzeigenden mehrstelligen Zahl nebeneinander angeordnet sind und die äußerst rechts befindliche Ziffernrolle vom Meßwertgeber aus angetrieben und jede weitere Ziffernrolle von der rechts von ihr befindlichen Ziffernrolle aus vermittels einer Zehnerübertragung fortgeschaltet wird, mit wenigstens einem Ziffernrollen aufweisenden Speichersatz zum Festhalten der jeweiligen-Zählerstellung des Zählwerkes, und mit einer Verstellvorrichtung zum An- bzw. Loskuppeln der Ziffernrollen des betreffenden Speichersatzes an den bzw. vom Meßwertgeber. Der Zweck der Erfindung ist die Schaffung einer Einrichtung der erwähnten Bauart, bei welcher in einfacher und betriebssicherer Weise eine Speicherung der Meßwerte ermöglicht wird, ohne daß besondere Zusatzgeräte benötigt oder umständliche Bedienungen in Kauf genommen werden müssen. Dies wird erfindungsgemäß dadurch erreicht, daß bei einem Zählwerk, dessen Ziffernrollen in an sich bekannter Weise auf drehbaren Zählwerkwellen befestigt sind, die sich neben-Accordingly, the present invention is concerned with a device for holding counter positions during a counting process with a multi-digit counter driven by the transducer, whose number wheels are arranged next to one another in the line direction of the multi-digit number to be displayed are and the rightmost digit roller driven by the transducer and each further digit roll from the digit roll to the right of it by means of a tens transfer is advanced, with at least one memory set having digit scrolls for holding the respective counter position of the counter, and with an adjusting device for coupling and uncoupling the digit rolls of the relevant memory record to or from the transducer. The purpose of The invention is to provide a device of the type mentioned, in which in a simple and reliable Way a storage of the measured values is made possible without the need for special additional devices required or cumbersome operations have to be accepted. This is according to the invention achieved in that in a counter, the number rollers in a known manner on rotatable Counter shafts are attached, which are located next to

Ein vereinfachtes Ausführungsbeispiel der Erfindung ist in der Zeichnung in perspektivischer Darstellung veranschaulicht, wobei einzelne Teile der Einrichtung in teilweise abgebrochener Ansicht gezeigt sind.A simplified embodiment of the invention is shown in perspective in the drawing illustrates, with individual parts of the device shown in a partially broken away view are.

Bei der in der Zeichnung dargestellten Einrichtung ist ein dreistelliges Zählwerk 11 gezeigt, dessen Zählwerkwellen 12 lotrecht verlaufen. Die Zehnerübertragung erfolgt mit Hilfe der gezahnten und ebenfalls lotrecht verlaufenden Zwischenachsen 13. Auf jeder der drei Zählwerkwellen 12 ist eine Ziffernrolle 14 befestigt, wobei die Ziffernrollen 14 des ZählwerkesIn the device shown in the drawing, a three-digit counter 11 is shown, the counter shafts 12 of which run perpendicular. The tens transmission takes place with the help of the toothed and also vertically extending intermediate axles 13. A number roller 14 is attached to each of the three counter shafts 12 , the number rollers 14 of the counter

11 in horizontaler Richtung nebeneinander angeordnet sind. Die zuäußerst rechts befindliche Zählwerkwelle 11 are arranged side by side in the horizontal direction. The counter shaft on the far right

12 wird über ein Zwischengetriebe vom Meßwertgeber 15 angetrieben, der beispielsweise ein elektrisch betätigter Schrittmotor sein kann, der in der Zeichnung jedoch nicht näher veranschaulicht ist. Die Zählwerkwellen 12 sowie die gezahnten Zwischenachsen 13 sind im Gestell 16 der Einrichtung gelagert; an diesem Gestell 16 kann auch der Meßwertgeber 15 befestigt sein. Ferner weist das Gestell 16 eine Frontplatte 17 auf, in welcher eine Reihe von Fenster 18 angebracht ist, durch welche hindurch die jeweils vorn befindlichen Zahlen der Ziffernrollen 14 sichtbar sind. In der Zeichnung zeigen die Ziffernrollen 14 des Zählwerkes 11 die Zahl »145« an. 12 is driven via an intermediate gear from the transducer 15 , which can be, for example, an electrically operated stepper motor, which is not illustrated in the drawing, however. The counter shafts 12 and the toothed intermediate axles 13 are mounted in the frame 16 of the device; The transducer 15 can also be attached to this frame 16. Furthermore, the frame 16 has a front plate 17 in which a row of windows 18 is attached, through which the numbers of the numerical rollers 14 located at the front are visible. In the drawing, the number rollers 14 of the counter 11 indicate the number "145".

Die Einrichtung weist nun einen ersten Speichersatz 21 auf, der aus den drei Ziffernrollen 22 besteht, die je auf den zugeordneten Zählwerkwellen 12 in axial verschiebbarer Weise angeordnet sind. Jede dieser drei Ziffernrollen 22 hat einen Zahnkranz 23, der zehn Zähne aufweist. Ferner hat jede Ziffernrolle 22 eine Leitkurve 24, welche die zugeordnete Zählwerkwelle 12 umgibt und sich gleichzeitig in der Achsrichtung der Zählwerkwelle 12 erstreckt, wie dies für die zuäußerst rechts befindliche Ziffernrolle 22 des Speichersatzes 21 ersichtlich ist. Die axiale Verschiebung der Ziffernrollen 22 erfolgt mit Hilfe einer dem Speichersatz 21 zugeordneten Verstellvorrichtung 25. Diese weist eine im Gestell 16 drehbar gelagerte Welle 26 auf, die an ihrem einen Ende mit einer an ihr befestigten Sperrklinke 29 versehen isL Auf der Welle 26 ist ferner für jede der Ziffernrollen 22 ein stiftförmiges Arretierorgan 27 sowie eineThe device now has a first memory set 21 , which consists of the three number rollers 22 , which are each arranged on the associated counter shafts 12 in an axially displaceable manner. Each of these three number wheels 22 has a ring gear 23 which has ten teeth. Furthermore, each digit roller 22 has a guide curve 24 which surrounds the assigned counter shaft 12 and at the same time extends in the axial direction of the counter shaft 12 , as can be seen for the digit roller 22 of the memory set 21 located on the extreme right. The axial displacement of the digit rollers 22 is carried out with the aid of a memory set 21 associated adjusting device 25. This comprises a rotatably mounted in the frame 16 shaft 26, ISL provided at its one end with a fixed to it pawl 29 on the shaft 26 is further for each of the number rollers 22 a pin-shaped locking member 27 and one

Blattfeder 28 befestigt, wobei die Blattfeder 28 auf der einen ebenen Fläche der zugeordneten Ziffernrolle 22 schleift und das Bestreben hat, die Ziffernrolle 22 in einer zum Arretierorgan 27 hinweisenden Richtung zu verschieben. An der Sperrklinke 29 greift eine Zugfeder 30 an, die das Bestreben hat, die freien Enden der Sperrklinke 29, der Arretierorgane 27, der Blattfedern 28, und damit auch die Ziffernrollen 22 nach oben zu bewegen. In der sich solchermaßen ergebenden oberen Endlage der Verstellvorrichtung 25 und der Ziffernrollen 22 des Speichersatzes 21 greifen die Arretierorgane 27 in die Zahnkränze 23 der Ziffernrollen 22 ein und sichern diese dadurch gegen eine Verdrehung. Da jedoch die Zählwerkwellen 12 sich weiterdrehen, müssen in dieser oberen Endlage die Ziffernrollen 22 von den Zählwerkwellen 12 losgekuppelt sein. Zu diesem Zweck ist der an jeder Zählwerkwelle 12 angebrachte Mitnehmer 31 auf solcher Höhe vorgesehen, daß er sich unter der Leit-Fixed leaf spring 28 , the leaf spring 28 dragging on the one flat surface of the assigned number roller 22 and strives to move the number roller 22 in a direction pointing to the locking member 27. A tension spring 30 acts on the pawl 29 and tends to move the free ends of the pawl 29, the locking members 27, the leaf springs 28, and thus also the number rollers 22 upwards. In the resulting upper end position of the adjusting device 25 and the number rollers 22 of the memory set 21 , the locking members 27 engage in the ring gears 23 of the number rollers 22 and thereby secure them against rotation. However, since the counter shafts 12 continue to rotate, the number rollers 22 must be uncoupled from the counter shafts 12 in this upper end position. For this purpose, the driver 31 attached to each counter shaft 12 is provided at such a height that it is located under the guide

ao kurve 24 der entsprechenden Ziffernrolle 22 hindurchdrehen kann. Die in der Frontplatte 17 angebrachten Fenster 32 sind dabei derart vorgesehen, daß die auf den Ziffernrollen 22 des Speichersatzes 21 befindlichen Zahlen nur dann in den Fenstern 32 erscheinen, wenn sich diese Ziffernrollen in der erwähnten oberen und ausgekuppelten Stellung befinden. In der Zeichnung ist somit der Speichersatz 21 in der losgekuppelten Endlage seiner Ziffernrollen 22 und die zugeordnete Verstellvorrichtung 25 in der dazugehörigen Endlage veranschaulicht. Wird hingegen die Sperrklinke 29 entgegen der Wirkung der Zugfeder 30 nach unten bewegt, . so drücken die Blattfedern 28 die Ziffernrollen 22 nach unten, bis die Mitnehmer 31 in der oberen Ecke der Leitkurven 24 einrasten und die Arretierorgane 27 außer Eingriff mit den Zahnkränzen 23 der Ziffernrollen 22 gelangt sind. In der sich solchermaßen ergebenden unteren Endlage sind sodann die Ziffernrollen 22 an die Zählwerkwellen 12 angekuppelt, und zwar derart, daß jede der Ziffernrollen 22 vorn dieselbe Zahl zeigt, wie die auf der gleichen Zählwerkwelle 12 befestigte Ziffernrolle 14 des Zählwerkes 11. Sollte im Augenblick des Uberganges aus der losgekuppelten in die angekuppelte Endlage eine oder mehrere der Ziffernrollen 22 noch nicht dieselbe Zahl zeigen wie die zugeordnete Ziffernrolle 14, so wird die betreffende Ziffernrolle 22 vermöge der Wirkung der Leitkurve 24 und des längs ihr schleifenden Mitnehmers 31 so lange gedreht, bis der Mitnehmer 31 in der erwähnten oberen Ecke der Leitkurve 24 eingerastet hat. Hierdurch wird in einfacher Weise erreicht, daß in der angekuppelten Endlage der Ziffernrollen 22 stets eine Ziffernübereinstimmung mit den Ziffernrollen 14 gewährleistet ist. In dieser angekuppelten Endlage der Ziffernrollen 22 des Speichersatzes 21 sind jedoch in den Fenstern 32 wegen der Absenkung der Ziffernrollen 22 die auf den letzteren befindlichen Zahlen nicht sichtbar. Die dem Speichersatz 21 zugeordnete Verstellvorrichtung 25 weist schließlich noch ein elektromechanisches Relais 33 auf, dessen verschiebbarer Relaisanker 34 unter dem Einfluß einer Druckfeder 35 steht. Die Druckfeder 35 hat das Bestreben, bei nicht erregter Relaiswicklung den Relaisanker 34 nach vorn zu schieben. In dieser vorderen Endlage des Relaisankers 34 kann die Sperrklinke 29 in den am Relaisanker 34 angebrachten Stift 36 einrasten, so daß dann die Sperrklinke 29 entgegen der Wirkung der Zugfeder 30 in ihrer unteren End- ao curve 24 of the corresponding number roller 22 can rotate through it. The windows 32 mounted in the front panel 17 are provided in such a way that the numbers located on the number rollers 22 of the memory set 21 only appear in the windows 32 when these number rollers are in the above-mentioned upper and disengaged position. In the drawing, the memory set 21 is thus illustrated in the uncoupled end position of its number rollers 22 and the associated adjusting device 25 in the associated end position. If, on the other hand, the pawl 29 is moved downward against the action of the tension spring 30,. the leaf springs 28 press the number rollers 22 downwards until the drivers 31 snap into the upper corner of the guide cams 24 and the locking members 27 have come out of engagement with the toothed rings 23 of the number rollers 22 . In the resulting lower end position, the number rollers 22 are then coupled to the counter shafts 12 , in such a way that each of the number rollers 22 shows the same number at the front as the number roller 14 of the counter 11 attached to the same counter shaft 12 Transition from the uncoupled to the coupled end position one or more of the number rollers 22 do not yet show the same number as the assigned number roller 14, the relevant number roller 22 is rotated by virtue of the effect of the guide curve 24 and the driver 31 sliding along it until the Driver 31 has locked in the mentioned upper corner of the guide cam 24. In this way, it is achieved in a simple manner that in the coupled end position of the number rollers 22, a figure correspondence with the number rollers 14 is always guaranteed. In this coupled end position of the number rollers 22 of the memory set 21 , however, the numbers on the latter are not visible in the windows 32 because of the lowering of the number rollers 22. The adjusting device 25 assigned to the memory set 21 finally also has an electromechanical relay 33 , the displaceable relay armature 34 of which is under the influence of a compression spring 35 . The compression spring 35 tends to push the relay armature 34 forward when the relay winding is not energized. In this front end position of the relay armature 34 , the pawl 29 can snap into the pin 36 attached to the relay armature 34 , so that the pawl 29 is then counter to the action of the tension spring 30 in its lower end

Claims

I The described. The device is particularly suitable in the laboratory for performing automatable measurements that extend over indefinite or longer periods of time, as can be the case, for example, when determining the melting temperatures of different samples in series. By means of the numeric rollers 14 of the counter 11, the furnace temperature changed for example according to a program can be displayed, it being assumed that all samples are in the same furnace. The melting process is determined photoelectrically and separately for each sample and one of the relays 33, 53 is also assigned to each sample. The relevant relay can be connected to the photocell assigned to the sample, if necessary by means of an electronic repeater, in such a way that it responds as soon as the sample begins to melt. By responding to the device's memory set assigned to the sample, the melting temperature of the sample is then immediately displayed and stored. Other applications of the device for carrying out a plurality of measurements of the same type without supervision are possible in large numbers. The multi-digit counter 11 and thus also the set of its digit rollers 14 can have any number of decimal places, and the same applies to the memory records. Likewise, the number of memory sets can be increased without difficulty depending on the desired requirements. Patent claims:

2. Device according to claim 1, characterized in that between each digit roller (22) of the relevant memory set (21) and the adjusting device (25) a ring gear (23) and a locking member (27) is so effective that in the disconnected end position of Digit roller (22) the locking element (27) engages in the toothed ring (23) and thus secures the digit roller (22) against rotation in its uncoupled end position, while in the coupled end position of the digit roller (22) the locking element (27) from the toothed ring ( 23) is disengaged and accordingly allows a rotation of the number roller (22) in accordance with the respective rotation of the counter shaft (12) assigned to this number roller (22) .

3. Device according to claim 1 and 2, characterized in that the driver (31) is attached to the counter shaft (12) , that the locking member (27) is attached to the adjusting device (25) , and that the guide cam (24) as well the ring gear (23) are provided on the relevant number roller (22) .

4. Device according to one of claims 1 to 3, characterized in that for reading the number rolls of both the counter (11) and the memory sets (21, 41, 61) a window field with side by side in the line direction and in the direction of the counter shafts (12 ) windows (18, 32, 52, 72) arranged one above the other in columns is provided, and furthermore the windows (32, 52, 72) provided for the number rolls (22, 42, 62) of the memory sets (21, 41, 61 ) in such a way are arranged offset in the column direction that the numbers located on the number rolls of the memory sets (21,41,61) only appear in the window openings when the number rolls concerned (z. B. 22) are in their uncoupled end position.

5. Device according to claim 1, characterized in that the adjusting device (25 ) assigned to a memory set (21) has a pawl (29) and a spring (30) in such a way that when the pawl (29) is engaged, the spring (30) is held taut and the number rollers (22) of this memory set (21) are then coupled to the associated counter shafts (12) , while the pawl is released

(29) the adjusting device (25) by the spring

(30) is pulled into the end position in which the number rollers (22) of this memory set (21) are uncoupled from the counter shafts (12).

6. Device according to claims 1 and 5, characterized in that the release of the pawl (29) of the adjusting device (25) by the relay armature (34) one of the relevant

position is held, in which thus the number rollers 22 are coupled to the counter shafts 12. If, however, the relay winding of the relay 33 is energized, the relay armature 34 moves backwards against the compression spring 35 and releases the pawl 29 . The latter is immediately pulled upwards by the spring 30 and thus the number rollers 22 are disengaged from the counter shafts 12. In the windows 32 , those numbers appear on the number rollers 22 which the number rollers 14 at the moment the relay 33 is energized Windows 18 have displayed so that the desired storage is thereby obtained.

The embodiment of the device according to the invention shown in the drawing now has, in addition to the first memory set 21 already explained, two further memory sets 41 and 61 , which are designed in the same way as memory set 21 with regard to all their associated parts. In this sense, memory set 41 has the Numerical rollers 42 with an associated adjustment device, of which the pawl is inscribed with 49 and the relay with 53 . The memory set 61 has the number rollers 62, the pawl 69 and the relay 73 in analogous lettering. All other parts of the memory sets 41 and 61 are not numbered. The pawls 49 and 69 are shown in their locked lower end position, so that the number rollers 42 and 62 are each in their coupled end position and therefore the numbers on them are not visible in the associated rows of windows 52 and 72, respectively. When using three memory sets 21, 41, 61 that can be triggered independently of one another, the numerical display of measured values can be stored which were obtained at the counter 11 at three arbitrarily predetermined times.

The device also expediently has a reset button 77 , by means of which one or more of the memory sets 21, 41, 61 can be transferred from the uncoupled end position of their number rollers back to the connected end position of the same, in order to make the relevant memory sets available for renewed storage . For this purpose, the reset button 77 is attached to a slide 78 which is guided in parallel in the frame and which is held in an upper position by means of a tension spring 79. The slide 78 has pegs 80 on which the pawls 29, 49, 69 can rest from below, as is shown for the pawl 29 . By temporarily depressing the reset button 77 , all of the pawls (e.g. 29) resting on the pin 80 are moved downward so that they engage, as is shown for the pawls 49 and 69 .

Finally, on the rightmost counter shaft 12, which is driven directly by the transducer 15 , a cam 81 is attached, which opens a contact 82 in a certain angular position, which is switched on in the common lead 83 leading to the relays 33, 53, 73 is. The angular position of the cam 81 is such that the contact 82 is always opened when the counter shaft 12 driven by the transducer 15 carries out a tens transmission, ie when several of the digit rolls 14 of the counter 11 are incremented at the same time. Opening the contact 82 thus prevents

that at the moment of a tens transfer one of the memory sets 21, 41 or 61 is transferred from the coupled end position of its digit rollers into the uncoupled end position of the same. One of the memory sets can therefore only respond before or after a tens transmission has been carried out and can cause storage, so that incorrect storage, in particular of the second result digit of the number to be stored, is prevented.

The device described can now be used practically as follows: By means of the counter 11 and its digit rollers 14 , the respective instantaneous value of the measured value transmitted by the transducer 15 is displayed, this instantaneous value being experienced as any changes in the course of time. The instantaneous value of the measured variable is to be stored at three predetermined times so that the stored instantaneous values can be read at any later time. The times of storage can for example be given by a timer or they can be made dependent on the occurrence of a certain event. The relays 33, 53, 73 are connected to the corresponding circuits 83 , which thus act as control circuits and can trigger the various memory sets 21, 41, 61 . For the time being, however, the key 77 is depressed, so that the number rolls of all three memory sets are transferred to the coupled end position, as has already been shown for the memory sets 41 and 61. In this coupled end position, the number rolls of the memory sets match the number rolls 14 of the counter 11, which are fastened on the same counter shaft 12 . If, before pressing key 77, the number rolls of a memory set were still in the uncoupled upper end position and are displaying a stored number that differs from the number displayed by counter 11 by means of its number rolls 14 , then pressing key 77 will make the Effect of the guide curves 24 and the driver pins 31 ensures the above-mentioned digit match when coupling without further measures.

After the key 77 has been depressed, there is in any case a match between all the number rollers located on the same counter shaft 12 , so that the number rollers of each of the memory sets take part in all the movements of the number rollers 14 of the counter 11. If, for example, the relay 33 is now energized, the pawl 29 snaps upwards due to the backward movement of the relay armature 34 and thereby brings the number rollers 22 of the memory set 21 into the uncoupled and upper end position, in which the stored number "145" is now in the windows 32 appear, provided that at the time of energization of the relay 33 the number rollers 14 of the counter 11 have also indicated the number "145" through the window 18. In an analogous manner, by means of the memory sets 41 and 61 , that number is stored which was visible on the number rollers 14 of the counter 11 at the time the relays 53 and 73 were energized. Once the memory records 21, 41, 61 have been addressed, the stored numbers are retained and visible in the windows 32, 52, 72 until the key 77 is pressed again.
