An Rechenmaschinen geschieht die Einstellung der zu multiplicirenden Zahl häufig dadurch, dafs man . an Zahnrädern mit beweglichen Zähnen (von denen je eines für jede Stelle der dekadischen Schreibweise vorhanden ist) die entsprechende Anzahl von Zähnen aus der unwirksamen in die wirksame Lage bringt, während die Höhe xles Multiplicators durch eine ihm entsprechende Anzahl von Umdrehungen dieser Zahnräder ihren Ausdruck findet. Hierbei tritt das Produkt durch die Gröfse der Drehung der von den verstellbaren Zahnrädern in Umlauf gesetzten festen Zahnräder in die Erscheinung. Mit solchen Rechenmaschinen kann man auch die für kaufmännische Zwecke wichtige Rechnungsform xy-f-st-f-uv-)- .... ausführen, indem man nach Hervorrufung des Produktes χ y die , das Resultat anzeigenden Scheiben nicht auf Null zurückbringt, sondern an den verstellbaren Zahnrädern die Einstellung des Werthes s besorgt und den Werth t durch entsprechend häufige Kurbelumdrehung zum Ausdruck bringt. Die das Ergebnifs anzeigenden Scheiben weisen dann den Werth χ y -f- s t auf. So kann man beliebig fortfahren und vermag stets das Endergebnifs abzulesen.On calculating machines, the number to be multiplied is often set by that one. on gears with movable teeth (one for each Digit of the decadic spelling is present) the corresponding number of teeth from the ineffective to the effective Location brings while the height xles multiplicator by a corresponding to it Number of revolutions of these gears finds its expression. This is where the product kicks in by the amount of rotation of the gears set in rotation by the adjustable gears fixed gears in the appearance. Such calculating machines can also be used for the form of invoices, which is important for commercial purposes xy-f-st-f-uv -) - .... execute, by adding the disks showing the result after evoking the product χ y does not bring it back to zero, but rather the setting of the on the adjustable gears Werthes s worried and the Werth t by correspondingly frequent turns of the crank to the Expresses. The disks showing the result then have the value h χ y -f- s t on. So you can go on at will and always be able to read off the final result.

Den Gegenstand der vorliegenden Erfindung bildet eine Einrichtung, die das ermöglicht.The subject of the present invention is a device which makes this possible.

In Fig. ι bedeute α eins der Zahnräder mit verstellbaren Zähnen, und zwar beispielsweise das Zehnerrad (fünf Zähne sind ausgeschoben gezeichnet).In Fig. Ι α means one of the gears with adjustable teeth, for example the tens wheel (five teeth are drawn out).

Ueber die Art, wie diese Zähne eingestellt werden, ist hier eine Erläuterung nicht erforderlich, da derartige Einrichtungen zur Genüge bekannt sind, andererseits der Erfindungsgegenstand von der Art der Einstellung ganz unabhängig ist. Durch Drehung der Kurbel b wird das Rad einmal in Umdrehung versetzt und nimmt das Zahnrad d entsprechend der Zahl der im Rade α vorgeschobenen Zähne mit. Auf alle Fälle, da mehr als neun Zähne auf jedem Rade α nicht vorhanden sind, ist der Uebertragungsvorgang nach Abrollung des Bogens c erledigt. Auf dem übrigen Theile der Drehung spielt sich die Zehnerübertragung zwischen den einzelnen Rädern d ab, deren ja ebenfalls für jede dekadische Stelle eins vorhanden ist. Hierzu wirkt der nicht mit Zähnen besetzte Theil des Umfanges von a in einer hier nicht näher zu beschreibenden Weise mit.There is no need to explain the way in which these teeth are set, since such devices are well known and, on the other hand, the subject matter of the invention is completely independent of the type of setting. By turning the crank b , the wheel is set in rotation once and takes the gear d with it according to the number of teeth advanced in the wheel α. In any case, since there are no more than nine teeth on each wheel α , the transfer process is done after the sheet c has unrolled. On the remaining part of the rotation, the tens transmission takes place between the individual wheels d , of which one is also present for each decimal place. The part of the circumference of a which is not occupied by teeth contributes to this in a manner which is not to be described in greater detail here.

Diesen bekannten Einrichtungen ist nun noch ein Zahnrad e (oder vielmehr ebenfalls je eins für jede dekadische Stelle) hinzugefügt, das unmittelbar oder mittelbar vom Rade d in Umlauf gesetzt wird. Es ist klar, dafs, wenn das Rad e so eingerichtet wird, dafs es nach jeder A gear wheel e (or rather also one for each decimal point) is now added to these known devices , which is set in circulation directly or indirectly by wheel d. It is clear that if the wheel e is arranged so that it changes according to each

Claims

Transfer of an intermediate result st or u ν etc. from α to d is released from the tooth mesh and brought back to zero, after each new transfer from α to d the product uv, w ζ etc. appears on the gear e.

A further consideration shows, however, that the disengagement of the wheel e not only after each complete transfer of a product χ y, st etc. from α to d, but after each individual revolution of the wheel a or. the crank b must be done. Assuming that the counter (wheels d) shows the value 35 from the last transfer, then the tens wheel d is at 3, the unic wheel d at 5. If now z. If, for example, the value 34 X 2 = 68 is added, the new total value is 103. The units disc c must therefore continue to rotate from 5 to 3, i.e. by 8 units, but the tens disc d from 3 to o, i.e. by 7 Units. If wheel d were to record the total rotation, the value it would display would be 78 instead of 68. This is due to the fact that the value 5 that was present on the unit's disk from the previous calculation process has grown over 10 through the addition of the 8 from the number 68 and as a result of this, during the last half of the last turn of the wheel a, the transfer of a unit to the Ten disk d has taken place.

So if you want to get a correct result in such cases, you have to solve the relationship between d and e with every turn of the crank, because with every turn of the crank a tens transfer can take place, and this solution must take place immediately after the development of the arc c against d , before a tens transfer may have taken place.

This facility can be implemented in very different and simple ways. Wheel e can be stored in a rocker arm f , which is moved in the direction of disengagement with each crank rotation by arm g, which is combined with it to form an angle lever, and by a lifting curve h connected to the crank, as soon as the teeth of wheel α have finished their transmission work ( Fig. 2).

The wheels e of the individual decadic digits must, however, be provided with their own numeric circuit, which, after the full rotation of a wheel, rotates the neighboring one, valued ten times higher, by one unit.

This ten circuit can be brought about in any way. For example, an oscillating lever k can be arranged between every two wheels e (FIG. 5) which carries an angle lever / (FIG. 3) at its free end. This is formed into a plate i at one leg end and carries a resilient pin m on the other. The angle lever usually assumes the position shown in FIG. The single disk (e ¹ in FIG. 5) carries a pin η (FIGS. 3 and 4) which, as soon as its position corresponding to 9 is exceeded, hits against a pin r of the angle lever / located in its path and hits the latter somewhat rotated so that it moves from the position of FIG. 4 to the position of FIG. Here, the pin m jumps over a fixed pin 0 seated on the lever k and catches itself behind it. The plate i of the angle lever is brought into the path of ten pins ρ by its movement, which are located on the side of the ^tens disc e 10 (FIG. 5) facing the lever k , and when the oscillation of the lever k in Enters the direction of the arrow in Fig. 3, the plate i pushes the tens wheel by one pin pitch further (Fig. 2). Later the same leg of the angle lever / hits a solid obstacle q (FIG. 3) and thereby brings the angle lever itself back into the position shown in FIG. 4, the resilient pin m jumping over the fixed pin 0 again.
