Description

Das Ausmessen der L.änge_ von Kurvenstrecken auf der Karte oder Zeichnung wird insbesondere beim Eisenbahn-, Kanal- oder Straßenbau allgemein unter Benutzung von Zirkeln und geraden Maßstäben durchgeführt. Diesis Verfahren ist zeitraubend und ungenau.Measuring the length of curves on the map or drawing is generally used in particular in the construction of railways, canals or roads performed by compasses and straight rules. This procedure is time consuming and inaccurate.

Nach der Erfindung werden Kurvenlineale an sich bekannter Art mit einer Längenteilung in den entsprechenden Maßstäben versehen, so daß durch Anlegen des Kurvenlineals an den zu messenden Bogen die Länge des Bogens in Metern oder einer beliebigen anderen Einheit unmittelbar ablesbar ist..According to the invention, curve rulers are of a known type provided a length division in the appropriate scales, so that by applying of the curve ruler on the arc to be measured the length of the arc in meters or any other unit can be read directly.

Inder Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Kurvenlineals mit Kurvenmaßstab dargestellt. Die Teilung wird beispielsweise als Strichätzung auf das Kurvenlineal aufgetragen. Der jeweils zugrunde liegende Maßstab und Kurvenradius ist auf dem Kurvenlineal vermerkt. Es kann ferner auch eine Teilung nach Winkelgraden auf dem Kurvenlineal angebracht sein.In the drawing is an embodiment of an inventive Curve rulers shown with curve scale. For example, the division is called Line etching applied to the curve ruler. The respective underlying yardstick and the curve radius is noted on the curve ruler. It can also be a division according to degrees on the curve ruler.
