Abstract
L'INVENTION CONCERNE DES REGLES PARALLELES UNIVERSELLES DU TYPE A RAILS, COMPORTANT UNE PLANCHE A DESSIN, UN RAIL HORIZONTAL MONTE SUR LA PLANCHE, UN CURSEUR HORIZONTAL MONTE COULISSANT SUR LE RAIL, UN RAIL VERTICAL RELIE AU CURSEUR HORIZONTAL POUVANT OSCILLER DANS UN PLAN PERPENDICULAIRE A LA SURFACE DE LA PLANCHE, ET UNE TETE MONTEE COULISSANTE SUR LE RAIL VERTICAL. SELON L'INVENTION, UN ORGANE MAGNETIQUE 13 EST DISPOSE LE LONG DU CHEMIN DE DEPLACEMENT DE LA PARTIE ARRIERE DU RAIL VERTICAL 6, ET UN ORGANE MAGNETIQUE 14 EST DISPOSE DU COTE DE LA PARTIE ARRIERE DU RAIL 6, CETTE PARTIE ARRIERE ETANT EXCITEE EN DIRECTION DE FLOTTEMENT PAR RAPPORT A LA SURFACE DE LA PLANCHE A DESSIN 1 PAR LA FORCE MAGNETIQUE DE REPULSION AGISSANT ENTRE LES ORGANES MAGNETIQUES 13 ET 14. L'INVENTION S'APPLIQUE NOTAMMENT AU DESSIN INDUSTRIEL.THE INVENTION RELATES TO UNIVERSAL PARALLEL RULES OF THE RAIL TYPE, INCLUDING A DRAWING BOARD, A HORIZONTAL RAIL MOUNTED ON THE PLANK, A HORIZONTAL SLIDER SLIDING ON THE RAIL, A VERTICAL RAIL CONNECTED TO THE HORIZONTAL SLIDER IN A PERIODIC PLANE. THE SURFACE OF THE BOARD, AND A SLIDING MOUNTED HEAD ON THE VERTICAL RAIL. ACCORDING TO THE INVENTION, A MAGNETIC ORGAN 13 IS PROVIDED ALONG THE TRAVELING PATH OF THE REAR PART OF THE VERTICAL RAIL 6, AND A MAGNETIC ORGAN 14 IS PROVIDED ON THE SIDE OF THE REAR PART OF THE RAIL 6, THIS REAR PART BEING EXCITED IN DIRECTION OF FLOATING WITH RESPECT TO THE SURFACE OF THE DRAWING BOARD 1 BY THE MAGNETIC REPULSION FORCE ACTING BETWEEN MAGNETIC ORGANS 13 AND 14. THE INVENTION APPLIES IN PARTICULAR TO INDUSTRIAL DRAWING.
