Description

Bei allen Rechenschiebern gleich welcher Ausführung stoßen bekanntlich die Teilungsstriche eines auf dem Grundschieber und der Schiebezunge angeordneten Skalenpaares gegeneinander. Bei häufigem Rechnen, besonders mit kleinieren, sogenannten Taschenschiebern, muß sich das Auge des Rechnenden sehr anstrengen, um die kleinen Teilungen genau einstellen und ablesen zu können.It is well known that all slide rules, regardless of the design, come across the graduation lines of a arranged on the base slide and the slide tongue Pair of scales against each other. With frequent arithmetic, especially with small, so-called Pocket pullers, the calculator's eye has to work very hard to find the little ones To be able to set and read the divisions precisely.

Bei der Erfindung, in Abb. i und a dargestellt, soll diese Erscheinung vermieden werden, indem zwischen den Teilstrichen des Grundschiebers a und der Schiebezunge b eine skalenfreie Linie c zwischengesetzt ist, die beliebig durch einen Trennstrich d abgegrenzt sein kann. Der Blick des Auges kann auf dieser freien Linie beim Hinundherschieben der Zunge ohne zu ermüden und mit besserer Sicht die oft schnell aneinanderlaufenden Skalenstriche einstellen. Einstellungsfehler werden vermieden, und bei einfacher Multiplikation oder Division kann auf die Verwendung dies Läufers verzichtet werden, da die Einstellung und das Ablesen über die freie Linie hinweg leicht und genau möglich ist. In Abb. z ist unter anderem die einfache Multiplikation 7,i - 1,n9=7,739 dargestellt. Aber auch bei Benutzung des Läufers, auf den bei mehrfachen nicht verzichtet werden kann, ist die Einstellung und Ablesung wesentlich übersichtlicher und vereinfacht.In the invention, shown in Fig. I and a, this phenomenon should be avoided by placing between the tick marks of the base slide a and the slide tongue b a scale-free line c is inserted, arbitrarily separated by a dividing line d can be delimited. The eye can look on this free line when sliding back and forth the tongue without getting tired and with a better view which often come together quickly Set scale marks. Adjustment errors are avoided, and with easier Multiplication or division can be dispensed with using this runner, because setting and reading across the free line is easy and precise is possible. In Fig.z, among other things, the simple multiplication 7, i - 1, n9 = 7.739 shown. But also when using the runner, which is not omitted with multiple can be, the setting and reading is much clearer and simplified.
