Description

Die vorliegende Erfindung soll hauptsächlich zum Messen des Neigungswinkels geneigter Flächen, besonders für artilleristische Zwecke,, dienen.The present invention is mainly intended for measuring the inclination angle of inclined ones Areas, especially for artillery purposes, are used.

Der Neigungswinkelmesr.er besteht in der Hauptsache aus dem Gehäuse α und den beiden Ringen b und c. Der Ring b läuft gut passend drehbar im Gehäuse a. Er ist außen als Schneckenrad und innen als Zahnrad ausgebildet. Der Ring c liegt drehbar im Ring b und kann mittels des Zahnrades d im Ring b bewegt werden. Der Ringe trägt außerdem eine Kreisteilung, an welcher die Drehung mittels eines festen Index gemessen werden kann. In die Lagerbuchse e des Zahnrades d sind Rasten I eingefräst, in welcher die Feder f einschnappt. Das Einstellen oder Weiterstellen des Ringes c wird dadurch beim Drehen des Zahnrades d deutlich fühlbar. Der Abstand von Rast zu Rast entspricht stets einer Einheit der Teilung auf c. Ferner ist durch diese Rasten und die Feder auch eine gewisse Sicherheit gegen unwillkürliches Verdrehen des Ringes c gegeben. Der Ring c ist zugleich Träger der beiden Libellen g und h. Die Libelle h liegt parallel zur Drehachse, Libelle g in Richtung des Durchmessers, also um 90 ° versetzt zu h. Libelle g dient zum Messen der Neigung und besitzt große Empfmdhchkeit. Libelle h soll, nur das ungefähre Horizontallegen der Drehachse ermöglichen, und es genügt deshalb geringere Empfindlichkeit. Die vorstehend beschriebene Anordnung ermöglicht jedoch nur eine Grobeinstellung. Znm Zwecke der Feineinstellung und Feinmessung dient die Schnecke i, mittels welcher der Ring b gedreht werden kann. Der Bewegung von b folgt selbstverständlich auch Ring c mitsamt den Libellen. Die Ablesung der Feineinstellung erfolgt an der Teiltrommel k der Meßschnecke i. The inclination angle meter consists mainly of the housing α and the two rings b and c. The ring b rotates in a well fitting manner in the housing a. It is designed as a worm wheel on the outside and a gear wheel on the inside. The ring is rotatable c b in the ring and may be d b in the ring by means of the gear wheel to be moved. The ring also has a circular graduation on which the rotation can be measured using a fixed index. In the bearing bushing e of the gear wheel d notches I are milled into which the spring f snaps. The setting or advancement of the ring c can be clearly felt when the gear wheel d is rotated. The distance from rest to rest always corresponds to a unit of the division on c. Furthermore, these notches and the spring also provide a certain security against involuntary rotation of the ring c. The ring c is also the carrier of the two dragonflies g and h. The vial h is parallel to the axis of rotation, vial g in the direction of the diameter, i.e. offset by 90 ° to h. Level g is used to measure the inclination and is very sensitive. Dragonfly h should only allow the axis of rotation to be approximately horizontal, and therefore less sensitivity is sufficient. However, the arrangement described above allows only a rough adjustment. The screw i, by means of which the ring b can be rotated, is used for fine adjustment and fine measurement. Of course, the movement of b also follows ring c together with the dragonflies. The fine adjustment can be read on the partial drum k of the measuring screw i.

Die Vorzüge der vorliegenden Konstruktion sind folgende:The advantages of the present construction are as follows:

Die grobe Einstellung der Libelle kann schnell und bequem erfolgen, ohne daß die Schnecke ausgeschaltet werden muß, wie dies bei anderen Konstruktionen erforderlich ist. Ferner sind die Intervalle der Grobeinstellung nicht nur ablesbar, sondern auch fühlbar. Durch das Einschnappen der Feder in die Rasten ist außerdem die Einstellung gegen unwillkürliches Verstellen gesichert.The rough adjustment of the level can be done quickly and easily without the Screw must be turned off, as is required in other designs. Furthermore, the intervals of the coarse adjustment can not only be read off but also felt. By snapping the spring into the notches, the setting is also against involuntary adjustment secured.
