Auf einer Prismaschiene α befindet sich in gerader Linie eine Eintheilung von beliebiger Länge. Beispielsweise sei eine Länge von o,75 m, in 1000 gleiche Theile getheilt, angenommen.A division of any length is located in a straight line on a prism machine α. For example, consider a length of o, 75 m, divided into 1000 equal parts, assumed.
Auf dieser Schiene liegt ein Schlitten tr, welcher, die schwalbenschwanzförmige Nuth der Schiene umfassend," der Länge nach hin- und herbewegt werden kann. Der an dem Schlitten angebrachte Nonius η gestattet die Ablesung von Yj o oder eines Heineren Theiles jedes Einzeltheiles der Schienentheilung.On this rail lies a slide tr which, encompassing the dovetail groove of the rail, can be moved back and forth along its length. The vernier η attached to the slide allows the reading of Yj o or a portion of each individual part of the rail division.
Auf dem Schlitten sind die beiden mittelst der Ständer mit einander verbundenen Fernrohre dx und d2, Fig. B1 befestigt, deren optische Achsen ex und e% mit der Oberfläche der Schiene in gleicher Ebene liegen. Andererseits ist jedoch die Verbindung der beiden Fernrohre eine solche, dafs die optische Achse des unteren einen rechten Winkel zur Eintheilungslinie der Schiene bildet, während die des oberen Fernrohres unter demjenigen Winkel justirt ist, welcher dem Verhältnifs der Gesammtlänge der Schieneneintheilung zu einer voraus bestimmten vielfachen Länge der Wirklichkeit entspricht. The two telescopes d x and d 2 , FIG. B 1 , which are connected to one another by means of the stands and whose optical axes e x and e % lie in the same plane with the surface of the rail, are fastened to the slide. On the other hand, however, the connection of the two telescopes is such that the optical axis of the lower telescope forms a right angle to the line of division of the rail, while that of the upper telescope is adjusted at that angle which corresponds to the ratio of the total length of the rail division to a predetermined multiple length corresponds to reality.
Dieses Verhältnifs ist in Fig. A durch die Achsenlinien ^1 und i3 dargestellt.This ratio is shown in Fig. A by the axis lines ^ 1 and i 3 .
Es sei der Apparat so aufgestellt, dafs die Fernrohrcombination mittelst des Schlittens so weit fortbewegt ist, dafs der Nullpunkt des Nonius mit dem Nullpunkt der Theilung der Schiene zusammenfällt.Let the apparatus be set up in such a way that the telescope combination by means of the slide is so is far removed, so that the zero point of the vernier coincides with the zero point of the division of the Rail collapses.
Wenn man nun die optische Achse des unteren Fernrohres nach demjenigen Punkt gerichtet hat, dessen Entfernung bestimmt werden soll, so mufs der Schlitten mit den Fernrohren so weit nach rechts bewegt werden, bis die optische Achse des oberen Fernrohres denselben zu bestimmenden Punkt trifft. Die wirkliche Ent fernung wird dann auf der Theilung der Schiene direct abgelesen.If you now point the optical axis of the lower telescope to that point whose distance is to be determined, the sledge with the telescopes must do so be moved far to the right until the optical axis of the upper telescope is the same to be determined Point hits. The real distance is then on the division of the rail read directly.
Selbstverständlich kann statt der Fernrohre ein Doppeldiopter in Anwendung gebracht werden.Of course, a double diopter can be used instead of the telescopes will.
