PATENTAMT.PATENT OFFICE.
Nachstehend beschriebene und durch beiliegende Zeichnung dargestellte Neuerung ist ein Apparat zur Höhenwinkelmessung aus freier Hand mit Verwendung geneigter Ziellinien (trigonometrisches Nivelliren). Hauptsächlich soll jedoch der vorliegende Quadrant als Zubehörstück von Geschützen benutzt werden, um dem Rohre die gehörige Höhenrichtung zu geben. Der Apparat soll bei Geschützen als Ersatz des Aufsatzes dienen, wenn das Ziel über das Geschützrohr hinweg nicht sichtbar ist, oder die Länge des Aufsatzes nicht hinreicht, oder auch um beim Richten bessere Deckung zu haben. Der Quadrant wird auf eine am Rohre sich als geeignet darbietende oder besonders angebrachte Fläche aufgesteckt.The innovation described below and illustrated by the accompanying drawings is an apparatus for measuring elevation angle by hand using inclined target lines (trigonometric leveling). Mainly, however, the present quadrant is intended as an accessory can be used by guns to give the barrel the proper direction of elevation give. The device is intended to serve as a replacement for the attachment in guns when the target is not visible over the gun barrel, or the length of the attachment is insufficient, or to have better coverage when judging. The quadrant will point to one that is appropriate on the pipe or specially attached surface.
Wie aus der Zeichnung ersichtlich, wird der Apparat gebildet durch ein Gefäfs α in Form eines rechtwinkligen Kreisausschnittes. Der Kreisbogen b ist mit einer Winkeleintheilung derart versehen, dafs der mit 0 bezeichnete Halbmesser sich vertical einstellt. Das Gefäfs a ist vollständig mit einer leicht beweglichen Flüssigkeit, wie Aether und ähnliches, gefüllt.As can be seen from the drawing, the apparatus is formed by a vessel α in the form of a right-angled section of a circle. The circular arc b is provided with an angular division in such a way that the radius marked 0 is vertical. The vessel a is completely filled with an easily mobile liquid, such as ether and the like.
Ein Schwimmer c, dessen Oberseite einen Nonius d (Fig. 3) trägt, ist an zwei um einen Scheitelpunkt e drehbar gelagerten Armen f befestigt. Die Drehachse der Arme f läuft in Spitzen g (Fig. 2), so dafs durch diese Führung die Empfindlichkeit des Apparates nicht beeinträchtigt wird.A float c, the upper side of which bears a vernier d (FIG. 3), is attached to two arms f rotatably mounted about an apex e . The axis of rotation of the arms f runs in points g (FIG. 2), so that the sensitivity of the apparatus is not impaired by this guidance.
Bei h ist eine durch eine Schraube verschliefsbare Oeffhung zur Füllung des Apparates angeordnet.At h there is an opening closable by a screw for filling the apparatus.
