Abstract

LA PRESENTE INVENTION CONCERNE UN INSTRUMENT DE MESURE DES ANGLES. SUIVANT L'INVENTION, L'INSTRUMENT DE MESURE DES ANGLES COMPREND DEUX CERCLES GRADUES 6 ET 7 SERVANT A DETERMINER DES ANGLES EN DIRECTION VERTICALE ET HORIZONTALE. CES CERCLES SONT DISPOSES DANS DES PLANS PARALLELES. L'AXE DE CES CERCLES COINCIDE AVEC L'AXE VERTICAL 13 DE L'INSTRUMENT DE MESURE. LE MOUVEMENT DE ROTATION DE LA LUNETTE 1 AUTOUR DE L'AXE 12 EST TRANSMIS AU CERCLE DE MESURE VERTICALE 6 PAR L'INTERMEDIAIRE D'UNE COMMANDE A MOYEN D'ENTRAINEMENT 2, 3, 4 ET 5. PAR L'INTERMEDIAIRE D'UN OBJECTIF 9, D'UN MIROIR DE RENVOI 10 ET D'UN OCULAIRE, ON PEUT SIMULTANEMENT LIRE LES DEUX ECHELLES 14 ET 15 DE GRADUATION DESDITS CERCLES. L'INVENTION PERMET DE REDUIRE L'ENCOMBREMENT ET LE POIDS DES INSTRUMENTS DE MESURE DES ANGLES.
