Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die in der Zeichnung im Längsschnitt dargestellte Orientierungsbussole unterscheidet sich von allen anderen Konstruktionen dadurch, daß bei Anwendung einer einfachen hochstehenden Magnetnadel a die Ablesung durch ein in bekannter Weise für Autokollimation eingerichtetes Fernröhrchen f stattfindet. Dies ist dadurch ermöglicht, daß ein kleiner Spiegel s rechtwinklig zur Längsachse der Nadel, dicht über dem Hütchen h und der Spitze * angebracht ist, und daß die — durch eine punktierte Linie dargestellte —· optische Achse des Fernröhrchens mittels eines Reflexionsprismas p derart gebrochen ist, daß ihr äußerstes Ende in einer Höhe mit dem Spiegel liegt. Die Nadel kann nur um wenige Grade schwingen.The orientation bus shown in longitudinal section in the drawing differs from all other constructions in that when a simple upright magnetic needle a is used, the reading takes place through a telescope f which is set up in a known manner for autocollimation. This is made possible by the fact that a small mirror s is attached at right angles to the longitudinal axis of the needle, just above the cap h and the tip *, and that the optical axis of the telescope - shown by a dotted line - is refracted in this way by means of a reflection prism p that its extreme end is level with the mirror. The needle can only swing a few degrees.

Wenn der Planspiegel rechtwinklig zur Achse des Ablesefernröhrchens steht, wird der Mittelstrich der Skala im oberen Teil des Gesichtsfeldes so reflektiert, daß er mit dem festen Indexstrich im unteren Teil des Gesichtsfeldes zusammenfällt.If the plane mirror is at right angles to the axis of the reading telescope, the middle line will be the scale in the upper part of the field of view is reflected in such a way that it corresponds to the fixed The index line in the lower part of the visual field coincides.

Beim Durchblick durch das Okular ist die Skala selbst unsichtbar und durch das Prisma bei t verdeckt. Nur das reflektierte Bild der Skala wird bei entsprechender Stellung des Planspiegels in der unteren Hälfte des Gesichtsfeldes sichtbar.When looking through the eyepiece, the scale itself is invisible and covered by the prism at t . Only the reflected image of the scale is visible in the lower half of the field of view when the plane mirror is positioned accordingly.

Das Prisma fi kann wie gezeichnet oder auch zwischen dem Objektiv 0 und dem Skalenplättchen t angebracht sein.The prism fi can be attached as shown or between the objective 0 and the scale plate t.

Diese Bussole ist zur magnetischen Orientierung von Polygonzügen in Gruben bestimmt. This Bussole is intended for the magnetic orientation of polygonal lines in pits.
