Bei der Construction der den Gegenstand vorliegender Erfindung bildenden Rechenmaschine war der Gedanke leitend, möglichst einfache Mechanismen zu /Verwenden.In the construction of the calculating machine which is the subject of the present invention the main idea was to use the simplest possible mechanisms.

Ein solcher Mechanismus ist in erster Linie die bekannte Leibniz'sehe Stufen walze, welche auch bei der neuen Rechenmaschine zur Bildung der Theilproducte verwendet wird. Bei der vorliegenden Maschine sind jedoch nicht, wie bei allen anderen dieses Element benutzenden Rechenmaschinen, eben so viele Stufenwalzen vorhanden als Factorenstellen, sondern hier wird nur eine einzige Stufenwalze oder ein einziger mit Stufenzähnen versehener Sector benutzt. Um den Mechanismus in dieser Art ganz wesentlich zu vereinfachen, sind die einzelnen Glieder des weiter zur Verwendung kommenden Schaltwerkes kreisförmig angeordnet. Such a mechanism is primarily the well-known Leibniz's step roller, which is also used in the new calculating machine for the formation of the partial products. at However, the present machine is not like all others using this element Calculating machines, just as many step rollers as factor positions, but here only a single stepped roller or a single sector provided with stepped teeth is used used. In order to simplify the mechanism in this way quite considerably, the individual Members of the switching mechanism that is still to be used are arranged in a circle.

Mit der Reduction der Stufenwalzen auf eine einzige und der kreisförmigen Anordnung des Schaltwerkes ist bei der neuen Maschine der complicirte, langgestreckte, viel Platz beanspruchende Mechanismus der Leibniz'sehen Maschine vermieden. Sie zeigt in ihrer Anordnung eine sehr gedrängte, handliche Form.With the reduction of the stepped rollers to a single and circular arrangement of the switching mechanism in the new machine is the complex, elongated one that takes up a lot of space Mechanism of Leibniz's see Machine avoided. Its arrangement shows a very compact, handy shape.

Auf beiliegender Zeichnung ist die neue Maschine schematisch dargestellt.The new machine is shown schematically in the accompanying drawing.

Auf der Drehachse 1 des Hohlcylinders 2 ist der in der Ruhelage nach unten weisende Sector .3 befestigt, während parallel und in gleichem Abstande zu dieser Drehachse die Wellen 4 in dem Cylinder 2 gelagert sind, deren jede mit einem zehn Zähne besitzenden Rade 5 versehen ist, welches sich auf seiner Welle verschieben läfst, aber, in Drehung versetzt, seine Welle 4 mitdreht. In Fig. 2 ist nur ein Schaltwerkglied mit seinem sämmtlichen Zubehör dargestellt. In dem Mantel des Cylinders 2 ist parallel zu jeder der Wellen 4 und senkrecht darüber ein Schlitz vorgesehen, durch den ein mit dem entsprechenden Zahnrade 5 verbundener Knopf 7 hindurchragt.On the axis of rotation 1 of the hollow cylinder 2 is the one pointing downwards in the rest position Sector .3 attached while parallel and at the same distance to this axis of rotation Shafts 4 are mounted in the cylinder 2, each of which has ten teeth Wheel 5 is provided, which can be shifted on its shaft, but, set in rotation, its shaft 4 rotates with it. In Fig. 2 is only one switching mechanism member with its entire Accessories shown. In the jacket of the cylinder 2 is parallel to each of the shafts 4 and a slot provided vertically above it, through which one with the corresponding gear wheel 5 connected button 7 protrudes.

Auf dem äufseren Umfange des Cylinders 2 sind neben jedem Schlitz 27 (Fig. 3) die gleichen Factorenzeichen ο bis 9 angebracht, so dafs durch Verschieben der Räder 5 'vermittelst des Knopfes 7 der betreffende Factor eingestellt werden kann. Ist dies geschehen, so wird die Welle ι und damit Sector 3 mit Hülfe der Kurbel 8 unter Vermittelung der Kegelräder 9, 10 gedreht, worauf dann der Factor auf der Ziffernscheibe 18 unter dem Schauloch erscheint, wenn vorher Nullstellung vorhanden war.On the outer circumference of the cylinder 2, next to each slot 27 (Fig. 3) are the same Factor signs ο to 9 attached so that by moving the wheels 5 'the Button 7 the relevant factor can be set. Once this has happened, the Shaft ι and thus sector 3 with the aid of the crank 8 with the intermediation of the bevel gears 9, 10 rotated, whereupon the factor appears on the dial 18 under the viewing hole, if previously zero setting was available.

Vor der rechten Stirnseite (Fig. 3) des Cylinders 2 ist ein zweiter Hohlcylinder, das Zählwerkgehäuse π auf der Drehachse 1 gelagert, welches auf dem dem Cylinder 2 zugekehrten Ende seiner Mantelfläche mit den Schlitzen 12 versehen ist. In diese pafst ein Zahn oder Stift 13, der seinerseits aus dem Mantel des Cylinders 2 seitwärts herausragt. Damit das Gehäuse 11 zum Cylinder 2 verstellt werden kann, sitzt ersteres lose auf der Achse 1, wird aber durch Feder 14 fest gegen die Stirnwand des Cylinders 2 gedrückt. Um das Zähl¹ werkgehäuse zu verstellen, zieht man es auf der Achse 1 zurück, so dafs der Stift 13 aus dem Einschnitt 12 des Zählwerkgehäuses heraustritt. Dasselbe ist jetzt frei drehbar und der Stift 13 kann in einen beliebigen anderen Einschnitt 12 greifen und so eine andere LageIn front of the right end face (FIG. 3) of the cylinder 2, a second hollow cylinder, the counter housing π, is mounted on the axis of rotation 1, which is provided with the slots 12 on the end of its jacket surface facing the cylinder 2. A tooth or pin 13 fits into this, which in turn protrudes sideways from the jacket of the cylinder 2. So that the housing 11 can be adjusted to the cylinder 2, the former sits loosely on the axis 1, but is pressed firmly against the end wall of the cylinder 2 by the spring 14. To ^{adjust the counter 1} mechanism housing, it is pulled back on the axis 1 so that the pin 13 protrudes from the incision 12 of the counter housing. The same is now freely rotatable and the pin 13 can engage in any other incision 12 and so in a different position

Claims

secure the meter housing. This relocation of the counter housing 11 is necessary when Multiply, divide, and extract the roots. The counting roller axles are in the counter housing 11 26 stored; on each of these are the gear 17, the dial 18 and the for Erasing the wheel 19 to be used is wedged, as well as the adjusting knob 20. The counting wheel shafts are arranged so that when the pin 13 engages in any of the Slots 12 form the extensions of the shafts 4. Each shaft 4 of the rear derailleur carries at its end facing the counter a wheel 25 provided with ten teeth. and it is the same with the same. Number of teeth provided counting wheel 17 on the cylinder 2 facing end of the shaft 26 so that the two gears 25 and 17 are flat lie against each other. So that the stuck on the shaft 4 gear 25 and on the shaft 26 arranged counting wheel 17 participate in the rotation of the first shaft, the However, the counter housing 11 can still be adjusted in relation to the cylinder 2 in the manner already indicated, the two wheels 25 and 17 connected by a detachable coupling. This coupling consists of driving pins 28 on the gear wheel 17 opposite the zero of the counting wheel 18, which in corresponding incisions of the wheel 25 grip on the shaft 4, so that no matter which of the wheels 17 at the rotation of the counter housing comes to rest against one of the wheels 25, the coupling is made.

A tens transmission, extinguishing device, not mentioned here and not shown in the drawing and so on complete the machine.

The handling of the machine and the purpose of its individual parts can be seen on the best make it clear with a multiplication example. The computer stands so that the housing 11 and the pen 14 is turned towards him, but the crank 8 is at the opposite end to his right. Let it be the number. 189 to be multiplied by the number 314. First adjust the housing 11 to the cylinder 2 in such a way that the setting button 20 located most to the right together with the associated viewing hole comes to lie opposite the slot 27 of the cylinder 2 which is located most on the right, whereby now the most to the right located shaft 4 is coupled to the rightmost shaft 26. Thereon all dials 18 are rotated by turning the adjusting knobs 20 so that in all Viewing holes of the cylinder 11, which are above the dials 18, zero can be seen. Then button 7 in the rightmost slot 27 on the number 9 of The adjacent scale is pushed, also in the following slots on the numbers 8 and i, in all others to o. If the crank 8 is now turned around once, then appear in the three peepholes on the right from right to left the numbers 9, 8 and 1, after two times Turns 8, 7 and 3. To get the result 189x314 you would have to use the crank Can be rotated 314 times if there is no relocation of the counter housing would be provided. With this facility, the number of However, revolutions only equal the checksum of the multiplier. The bill 189x314 happens as follows:

First the crank is turned 4 times, then 4 X 189 = 756 in the peepholes. The counter housing is now relocated to the right by an incision in order to oblique writing of the written calculation in the second part of the product to give a value ten times as high from 189, and turn the crank once. Here is the rightmost wave 4 with the second wave 26 seen from the right coupled, and the first shaft 26 together with the dial. stays during this and that following turns at rest. The counter housing will now be increased by one The incision was made and the crank turned three times. The partial product from 3 and 189 gets thereby the hundredfold value; 59346 is now in the peepholes.

The process corresponds to written arithmetic, which is shown in the following picture:

189 X 4 == 756

189 X 10 = 1890

189 χ 300 = 56700

59346.

The calculation rules for this machine also differ from those of the known ones not from, but here with subtraction and division instead of a switch, an opposite occurs directed crank rotation.
