  Vorrichtung zum Vergrössern oder Verkleinern einer Strecke in einem bestimmten Verhältnis. 



   Um beim Perspektivzeichnen anvisierte Strecken ohne Schätzung oder Umrechnung schnell und genau im vergrösserten oder verkleinerten Massstab zu Bilde zu bringen, bedient man sich vorliegender Vorrichtung, welche aus dem Visierstab a und einem zu ihm drehbaren Stab c sowie einem senkrecht stehenden und verschiebbaren Stab b besteht. 



   Visiert man mit dem   Stab a   und dem Schieberstab b eine Strecke einer Landschaft an, welche auf der Visiervorrichtung eine Sehwinkelstrecke   A   ergibt, so kann man diese Sehwinkelstrecke in beliebiger Länge B mittels des drehbaren Stabes c auf dem Schieber- 
 EMI1.1 
 übertragen. 



   Der Winkel   a   zwischen Stab a und c bleibt für ein und dasselbe Bild ein für allemal beibehalten. 



   Die weiteren anvisierten Strecken ergeben sich durch die verschiedene Lage des Schieberstabes b als homologe Strecken innerhalb des   Stabwinkels.   



   Auf beschriebener Vorrichtung kann nebstbei ein Transporteur zum Ablesen des Winkels   a   aufgesetzt werden. 



   Mit Zuhilfenahme des Stabes c können auch die Winkel   ce   der fallenden und steigenden perspektivischen Linien durch Anvisieren des Landschaftbildes usw. genau ermittelt und übertragen werden. 



   Zugleich können mit beschriebener Vorrichtung durch Anlegen an geometrische Körper oder Bildfläche dieselben im   vergrösserten   oder verkleinerten Massstabe ohne Schätzung oder Umrechnung schnell übertragen werden. 



   Weiters kann mittels der Stäbe a und b der   Augenhorizont   ermittelt werden. 



   Desgleichen mittels der Stäbe c und b der Augpunkt sowie unter Zuhilfenahme der 
 EMI1.2

  Device for enlarging or reducing a distance in a certain ratio.



   In order to quickly and accurately create images on an enlarged or reduced scale without estimating or converting the routes targeted during perspective drawing, the present device is used, which consists of the sighting rod a and a rod c that can be rotated relative to it, as well as a vertical and displaceable rod b.



   If you aim at a stretch of landscape with rod a and slide bar b, which results in a visual angle range A on the sighting device, you can adjust this visual angle range in any length B using the rotatable rod c on the slide
 EMI1.1
 transfer.



   The angle a between bars a and c is retained once and for all for one and the same image.



   The other targeted routes result from the different positions of the slide rod b as homologous routes within the rod angle.



   A conveyor for reading the angle a can be placed on the device described.



   With the aid of the rod c, the angles ce of the falling and rising perspective lines can also be precisely determined and transferred by aiming at the landscape, etc.



   At the same time, with the described device, by placing it on geometric bodies or image surfaces, the same can be quickly transferred on an enlarged or reduced scale without estimation or conversion.



   Furthermore, the eye horizon can be determined by means of rods a and b.



   Likewise by means of rods c and b the eye point and with the aid of
 EMI1.2
