Description

Bei dein Erfindungsgegenstand handelt es sich um eine Abänderung das Rechenschiebers oder Kreisrechenschiebers nur zur Ablesung N-ton Einmaleinszahlen.The subject of your invention is a modification that Slide rule or circular slide rule only for reading N-ton multiplication numbers.

Die Skala der neuen Vorrichtung hat eine Strichteilung, welche nur die erforderlichen Zahlen und Striche enthält. Die Abstände entsprechen ihren Logarithmen.The scale of the new device has a line graduation, which only contains the required numbers and dashes. The distances correspond to their logarithms.

Abb. i veranschaulicht eine Ausführungsmöglichkeit in Kreisform. Die Fläche, welche der innere Kreis a einschließt, ist eine Scheibe, und darunter ist die Scheibe b mit dem größeren Radius. Beide Scheiben sind in der Mitte c drehbar verbunden.Fig. I illustrates an embodiment in a circular shape. the The area enclosed by the inner circle a is a disk, and below it is the disk b with the larger radius. Both discs can be rotated in the middle c tied together.

Abb. 2 zeigt eine weitere Ausführungsform.Fig. 2 shows a further embodiment.

Auf einem Stab d mit einer Anschlagnase oder -leistee sind wieder die Zahlen wie auf der größeren Scheibe der Abb. i angeordnet. Dann sind für jede Zahl ein oder zwei Klötzchen f vorhanden, deren Länge genau dem Logarithmus dieser Zahl entspricht, wie auch bei den Zahlen der Einteilung auf dem Stab d. Werden; nun zwei oder drei der Klötzchen f gegen den Anschlag a geschoben, so kann am Ende das Produkt abgelesen «-erden. Die Klotzwahl von Abb. 2 ergibt 2 X 7 = i.4.On a bar d with a stop lug or ledge are again the numbers as arranged on the larger disk of Fig. i. Then are for each Number one or two blocks f available, the length of which corresponds exactly to the logarithm of this As with the numbers, number corresponds to the division on staff d. Will; now two or three of the blocks f pushed against the stop a, so can at the end read the product «-ground. The choice of blocks in Fig. 2 results in 2 X 7 = i.4.

PATENTANSPROCHE: i. Spiel-Einmaleins, dadurch gekennzeichnet, daß unter Anwendung des bekannten Rechenschieberprinzips der logarithmischen Skalenteilung zwei gegeneinander vierdrehbare oder verschiebbare kreisförmige oder geradlinige Skalenträger mit nur die Zahlen des Einmaleins enthaltenden Skalen versehen sind. PATENT CLAIM: i. Game multiplication tables, characterized in that using the well-known slide rule principle of the logarithmic scale division two circular or rectilinear ones that can be rotated or displaced against each other in four directions Scale carriers are provided with scales containing only the multiplication tables. 2. Spiel-Einmaleins nach Anspruch i, dadurch gekennzeichnet, daß bei kreisförmiger Ausbildung der beiden Skalen ihre Skalenträger (ca, b) drehbar miteinander verbunden sind. 2. Game multiplication table according to claim i, characterized in that with a circular design of the two scales their scale carriers (ca, b) are rotatably connected to one another. 3. Spiel-Einmaleins nach Anspruch i, dadurch gekennzeichnet, daß bei geradliniger Ausbildung der Skalen eine Skala auf einem Stab (d) angeordnet ist, der am Skalenanfang einen Anschlag (e) besitzt, während an Stelle der zweiten Skala für jede Zahl des Einmaleins ein oder zwei Klötzchen (f) vorhanden sind, deren Längen dem Logarithmus der betreffenden Zahl entsprechen.3. game multiplication table according to claim i, characterized in that if the scales are straight, a scale is arranged on a stick (d) is, which has a stop (e) at the beginning of the scale, while in place of the second There are one or two blocks (f) for each number in the multiplication table, their Lengths correspond to the logarithm of the number in question.
