  Läufer für   Rechenschteberoder dergt.   



   Angemeldet am 19. November   1907.-Beginn   der   Patentdauer : 1.   September 1908. 



   Den Gegenstand der Erfindung bildet ein Läufer für Rechenschieber, der aus einem eigenartig gestalteten Glaskörper gebildet ist, die einerseits eine Vergrösserung der ab- lesenden Teilung bewirkt und andererseits die Kontinuität der Teilung nicht aufhebt und gleichzeitig die bei gewöhnlichen Linsen auftretende Lichtdispersion verhindert. 



   In der Zeichnung ist der Erfindungsgegenstand dargestellt und zeigt :
Fig. 1 eine schaubildliche Darstellung des Läufers und
Fig. 2 schematisch die Art der Wirkung des Glaskörpers. 



   Der Glaskörper besteht aus einem zylindrisch konvexen Teil a, t, an welchen sich   . beiderseits zylindrisch konkave   Teile a, c bezw. b,   d   anschliessen, die in die ebenen Teile c, e bezw.   o   f übergehen. 



   Wie ans der schematischen Darstellung in Fig. 2 ersichtlich, wird der zylindrisch konvexe Teil a,   b des Glaskörpers   die Teilung an der eingestellten Stelle des Rechen- schiebers stetig vergrössern, die anschliessenden Teile a, c bezw. b,   d   werden die Teilung verkleinern und es wird die Verkleinerung gegen die ebenen Teile hin stetig abnehmen und so ein Übergang zur nicht vergrösserten bezw. nicht verkleinerten Teilung geschaffen. 



   Die Kurven a, c bezw. b,   d   sind zweckmässig Konchoiden. 



   Auf diese Art ist eine   Kontinuität   der in Betracht kommenden Teilung erzielt und das Auge ermiidet nicht so als bei Anwendung eines gewöhnlichen   Vergrösserungsglases.   



   PATENTANSPRÜCHE : 
1.   Läufer für Rechenschieber und dgl. gekennzeichnet   durch einen   Glaskörper,   dessen mittlerer Teil (a, b) zylindrisch konvex die anschliessenden Teile   (a,   c bezw. b,      zylindrisch konkav und die hieran anschliessenden Teile   (r,     e bezw. d, f) eben   gestaltet sind. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Runner for calculators or dergt.



   Registered on November 19, 1907.-Patent period begins on September 1, 1908.



   The subject of the invention is a runner for slide rule, which is formed from a peculiarly designed glass body, which on the one hand causes an enlargement of the reading graduation and on the other hand does not cancel the continuity of the graduation and at the same time prevents the light dispersion that occurs with ordinary lenses.



   The subject of the invention is shown in the drawing and shows:
1 shows a diagrammatic representation of the rotor and
Fig. 2 shows schematically the type of action of the glass body.



   The glass body consists of a cylindrically convex part a, t, on which. both sides cylindrically concave parts a, c respectively. connect b, d, which are in the flat parts c, e respectively. o f skip.



   As can be seen from the schematic representation in FIG. 2, the cylindrically convex part a, b of the glass body will steadily increase the division at the set point of the slide rule, the following parts a, c and b, d will reduce the division and the reduction towards the flat parts will steadily decrease and so a transition to the non-enlarged resp. not reduced pitch created.



   The curves a, c respectively. b, d are conveniently conchoid.



   In this way a continuity of the division under consideration is achieved and the eye does not avoid as much as when using an ordinary magnifying glass.



   PATENT CLAIMS:
1. Runner for slide rules and the like. Characterized by a glass body, the middle part (a, b) of which is cylindrically convex, the adjoining parts (a, c and b, cylindrically concave and the adjoining parts (r, e and d, f ) are just designed.
