Description

Bei .den bekarintet:kteisfödnigdn° Reffienschiebern sinfl. zumeist nur auf einer Seitenfläche der Kreisscheiben zwei körrespöndieiende Skalen am Umfang mit radial angeordneten Skalenstrkten vorgesehen. Demgegenüber gestattet der Gegenstand . der Erfindung die gleiche Anordnung der Skalen eine'S.'ygebräuchlichen Rechenstabs und gleiche Handhabung, die dadurch erreicht wird, der gebräuchliche' Rechenstab gewissermaßen die Felge eitles radförmigen, um eine ortsfeste drehbaren Körpers herumgelegt ist. Der Dnkh- messer des Rades kann je nach der gewünschten Ab- , Lesegenauigkeit innerhalb der durch die Handlichkeit gegebenen Grenzen gewählt werden.With .den: kteisfödnigdn ° Reffienschiebern sinfl. mostly only on one side surface of the circular disks two corresponsive scales are provided on the circumference with radially arranged scale thicknesses. In contrast, the subject allows. the invention has the same arrangement of Scales a 's.'y common slide rule and same handling that is achieved by the common 'slide rule, so to speak the rim vain wheel-shaped, around a stationary one rotatable body is lying around. The Dnkh- The diameter of the wheel can be selected depending on the desired accuracy, reading accuracy within the limits given by the handiness.

Der Gegenstand der Erfindung ist in den'Abb. A,. B, C dargestellt.The subject of the invention is shown in Figs. A ,. B, C shown.

In dem Ständer i ist der radförmige Körper 2 auf der Welle 3 drehbar gelagert. -Der; radförmige, Körper 2 trägt auf seinen MantelfIächen@4, 5 und auf der äußeren Mantelfläche 6 der ringförmig ausgebildeten, drehbar auf dem Körper 3 gelagerten Zunge 6 die Skalen des üblichen Rechenstabs. Bei 7 ist ein verstellbares Fenster mit Haarstrich zum Einstellen- der. Skalenstriche und züm Ablesen des Resultats angebracht. Weitere Skalen, z. B. für trigonometrische Funktionen, können an den Seiten-Bächen 8, 9 des Körpers 2 vorgesehen werden, für e ren Ablesung mit Haarstrichen versehene Fenster io, ii angeordnet sind. An den Seitenflächen 'i#K#Körpers können außerdem Tabellen, Formeln, ?I@Mtanten usw. aufgezeichnet'sein.In the stator i, the wheel-shaped body 2 is rotatably mounted on the shaft 3. - The; The wheel-shaped body 2 carries the scales of the usual slide rule on its jacket surfaces @ 4, 5 and on the outer jacket surface 6 of the ring-shaped tongue 6 rotatably mounted on the body 3. At 7 there is an adjustable window with a hairline for adjusting the settings. Scale lines and to read the result attached. Other scales, e.g. B. for trigonometric functions, can be provided on the side streams 8, 9 of the body 2, for e Ren reading provided with hairlines windows io, ii are arranged. Tables, formulas,? I @ items, etc. can also be recorded on the side faces of the body.
