Description
Equerre mobile à rapporteur d'angles. La présente invention a pour objet une équerre mobile que l'on peut mettre à l'angle désiré au moyen d'un rapporteur d'angles.
Ge .dernier peut être enlevé afin de pou voir utiliser l'équerre sans être gêné par sa présence.
Le dessin montre, en fig. 1, une coupe verticale .d'une forme d'exécution de l'appa reil, donnée à titre d'exnple.
La fig. 2 est une vue de dessus. L'apparreil représenté comprend: da branche 1 de l'équerre dont le moyeu 2 pivote dans le moyeu 3 de la branche 4;
une vis 5 permet de bloquer les deux bran ches 1 et 4, l'une par rapport à l'autre; le disque 6 gradué en degrés peut être bloqué en même temps sur la 'branche 4 au moyen de l'écrou molleté 7;
il porte, d'autre part, une cheville 8 dont la partie supérieure est rivée sur de disque 6 et qui est engagée librement, sans jeu, dans la branche 1.
La branche 4 comporte un vernier 9 qui, dans le cas de l'exécution présentée, permet la lecture du 20me de degré.
On se sert de l'appareil décrit de la façon suivante: La vis 5 et l'écrou 7 étant débloqués, on met la branche 4 sur l'angle désiré et on fige l'ensemble au moyen de l'écrou molleté 7.
Après avoir bloqué la vis 5, il suffira d'en lever l'écrou molleté 7 pour ssépaxer le disque 6 de L'ensemble et l'équerre sera prête à être utilisée.
Four prendre la mesure d'un angle exis- tant, on présentera l'équerre sans le disque et avec la vis 5 @débloquée sur la pièce dont il faut mesurer l'angle, puis on remontera le disque pour faire la lecture.
Movable square with protractor. The present invention relates to a movable square which can be set to the desired angle by means of an angle protractor.
Ge .dernier can be removed in order to be able to use the square without being hampered by its presence.
The drawing shows, in fig. 1, a vertical section .d'une embodiment of the apparatus, given by way of example.
Fig. 2 is a top view. The apparatus shown comprises: da branch 1 of the square, the hub 2 of which pivots in the hub 3 of the branch 4;
a screw 5 makes it possible to block the two branches 1 and 4, one with respect to the other; the disc 6 graduated in degrees can be locked at the same time on the branch 4 by means of the knurled nut 7;
it carries, on the other hand, an ankle 8, the upper part of which is riveted to the disc 6 and which is engaged freely, without play, in the branch 1.
The branch 4 comprises a vernier 9 which, in the case of the execution presented, allows the reading of the 20th of a degree.
The apparatus described is used as follows: The screw 5 and the nut 7 being released, the branch 4 is placed at the desired angle and the assembly is fixed by means of the knurled nut 7.
After having locked the screw 5, it will suffice to lift the knurled nut 7 to sepax the disc 6 from the assembly and the square will be ready to be used.
To take the measurement of an existing angle, we will present the square without the disc and with the screw 5 @ released on the part whose angle must be measured, then we will reassemble the disc to read it.
