Description
Instrument pour 1e dessin. La presente invention a pour objet un instrument pour 1e dessin, qui est constitue par une Plaque presentant au moins un cöte rectiligne, cette Plaque comportant au moins une ouverture presentant des Bords recti- lignes, 1e tout clispose de fa#,on que Fon puisse dessitier direetement au moins les ängles de 15, 30, 45, 60 et 900. Instrument for the 1st drawing. The subject of the present invention is an instrument for drawing, which consists of a plate having at least one rectilinear side, this plate comprising at least one opening having rectilinear edges, the whole clispose so that Fon can directly remove at least angles of 15, 30, 45, 60 and 900.
Cet. instruinent presente Bone un avantage serieux par rapport aux equerres usuelles qui ne permettent de dessiner chacune que quel- ques-uns des angles susindiques. Quant ä, 1'angle de 150, il ne peut eire trace directe- inent avec ces equerres; il faut tracer une droite ä -150 et puis une autre droite ä 300 par rapport ä, une meine droite. This. This instruction presents Bone with a serious advantage over the usual squares which only allow one to draw a few of the above-indicated angles. As for the angle of 150, it cannot be traced directly with these squares; you must draw a straight line at -150 and then another straight line at 300 with respect to ä, a straight line.
Le dessin annexe represetite, ä, titre d'exemple, deux fornies et des variantes d'exe- eution de 1'instrument objet de 1'invention. The appended drawing represents, by way of example, two forms and variants of execution of the instrument which is the subject of the invention.
1,a fig. 1 montre un instrument de forme earree, et la fig. `? un instrument en forme d'equerre. lies fig. 3 < t 7 representent eltacune une variante. 1,a fig. 1 shows an earree-shaped instrument, and fig. `? a square-shaped instrument. lie fig. 3 < t 7 represents every variant.
L'instruntent selon la fig. 1 est eonstitue par wie Plaque plane, mince, mais suffisam- ment. rigide, de forme carree, dort 1e cöte peut avoir, par exemple, une longueur de 2-10 min. La pratique a montre que ce forinat est celui qui repond 1e mieux aux exigences du dessinateur teehnique. Il va sans dire que Fon peut lui Bonner des dimensions plus grandes ou plus petites; notaminent on pour- rait lui Bonner un format de poche. Cinq longues fentes reetilignes, suffisam- ment larges pour que Fon puisse y introduire et y faire coulisser la Pointe d'un instrument servant ä tracer des lignes (erayon, tire- ligne), sont entaillees Jans la Plaque. Ces fentes eomiergent vers 1'un des angles de la Plaque et, dans cet exemple, forment av ec les cötes de 1'angle droit des angles de 15, 30, 45, 60 et 750. L'angle compris entre deux fentes eonsecutives est constant (150). The instrument according to FIG. 1 is constituted by a flat plate, thin, but sufficient. rigid, square in shape, sleeps the rib can have, for example, a length of 2-10 min. Practice has shown that this format is the one that best meets the requirements of the technical draftsman. It goes without saying that Fon can give him larger or smaller dimensions; in particular, we could give it a pocket format. Five long straight slits, wide enough to allow the point of an instrument used to draw lines (rayon, draw-line) to be inserted and slid through them, are cut in the Plate. These slits emerge towards one of the angles of the Plate and, in this example, form with the sides of the right angle angles of 15, 30, 45, 60 and 750. The angle between two consecutive slits is constant (150).
L'instrument permet Bone de dessiner di- rectement, en prenant comme ligne origine 1'un ou 1'autre des cötes exterieurs, tous les angles multiples de 1'angle 150, de 15 ä 900. 11 remplace donc avec avantage les equerres ä 45 et ä 30 et 600. The instrument allows Bone to draw directly, taking as origin line one or the other of the external sides, all the angles multiple of the angle 150, from 15 to 900. It therefore replaces with advantage the squares at 45 and at 30 and 600.
Pour augnienter 1e nombre d'applications de cet instrunient, an peut munir ehacun des deux cötes de 1'angle droit vers lequel con- vergent les fentes dune graduation pour la mesure des lotigueurs et les deux autres eötes de la Plaque d'tine graduation pour la mesure des angles, enRTI ID="0001.0271" WI="13" HE="4" LX="1283" LY="1839"> prenant 1e sommet de 1'angle droit eomme origine des angles. 0n pourrait egalement tracer des graduations sur 1e Bord des fentes. To increase the number of applications of this instrument, one can equip each of the two sides of the right angle towards which the slits converge with a scale for the measurement of the lengths and the other two sides with the Plate of a graduation for the measure of the angles, in RTI ID="0001.0271" WI="13" HE="4" LX="1283" LY="1839"> taking the vertex of the right angle as the origin of the angles. You could also draw graduations on the edge of the slots.
La Plaque peut et.re faire en une matiere plastique transparente oii non, en metal leger ou en bois, par exemple. Dans 1e cas oü elle est en une mauere transparente, les ehiffres des graduations pourraient et.re marques sur les deux faces, les divisions de la graduation etant marquees sur une Beule faee et etant vi- sibles de 1'autre röte ä cause de la transpa- rence de la matiere. The Plate can be made of a transparent plastic material or not, of light metal or wood, for example. In the case where it is of a transparent material, the graduation figures could be marked on both sides, the divisions of the graduation being marked on one side and being visible from the other side because of the transparency of the material.
Entre les fentes rectilignes, an pourra en- tailler dann la Plaque des fentes curvilignes permettant de tracer des lignes courbes, comme eelles que Fon traee ä 1'aide des pisto- lets de dessinateur. 0n pourrait egalement pereer Jans la Plaque des eercles de differents diametres, ainsi que des Profils et des hexa- Bones pour dessiner les tetes de boulons en elevation et en plan. A röte de chaque fente rectiligne, de chaque cercle, hexagone ou Pro fil, an inscrira, de preference, une mention indiquant 1'inclinaison de la fente, 1e diamet.re du cercle, 1e calibre du boulon. Between the straight slits, curvilinear slits can be cut in the Plate, allowing curved lines to be drawn, such as those drawn with draftsmen's guns. Circles of different diameters could also be drilled into the Plate, as well as Profiles and Hexagons to draw the bolt heads in elevation and in plan. Next to each rectilinear slot, each circle, hexagon or profile, a note should preferably be written indicating the inclination of the slot, the diameter of the circle, the gauge of the bolt.
Dans sa forme d'execution la plus com- plete, 1'instrument pourra remplir ä la fois 1e röle d'equerre ä 450, d'equerre ä 30 et 600, de pistolet, de ehablon, de rapporteur, de regle graduee. In its most complete form of execution, the instrument can simultaneously fulfill the role of square at 450, of square at 30 and 600, of pistol, of ehablon, of protractor, of graduated ruler.
La fig. 2 montre un Instrument eonstitue par une Plaque ayaut la forme d'un triangle rectangle isocele (equerre usuelle ä 450). Dans Bette Plaque sont entaillees deux fentes recti- lignes eonver geant v ers 1'un des angles de 450 et formant entre elles ui angle de 150. Elles forment avec l'une des cathetes respective- ment des angles de 15 et de 300, et avec 1'autre cathete des angles de 75 et de 600. Cet instru- ment permet done, tout comme 1e preeedent, de dessiner tous les angles multiples de 150, de 15 ä 900. Ici aussi an peut prevoir des gra- duations et quelques fentes curvilignes ou des Profils du genre de ceux mentionnes plus haut. La Plaque peut etre faite en une ma- tiere transparente ou opaque. fig. 2 shows an Instrument consisting of a Plate in the shape of an isosceles right-angled triangle (usual square at 450). In Bette Plaque are cut two rectilinear slots converging towards one of the angles of 450 and forming between them an angle of 150. They form with one of the catheters angles of 15 and 300 respectively, and with the other catheter angles of 75 and 600. This instrument therefore makes it possible, like the previous one, to draw all angles multiple of 150, from 15 to 900. curvilinear slots or Profiles of the kind mentioned above. The Plate can be made of a transparent or opaque material.
