KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung soll ermöglichen, beim perspektivischen Zeichnen auf einfache Weise die Winkel, unter denen die wagerechten Kanten eines zu zeichnenden Körpers von der wirklich wagerechten Richtung scheinbar abweichen, sowie die Ausdehnungen der senkrechten .und schiefen (in Wirklichkeit aber wagerechten) Kanten festzustellen und zeichnerisch richtig wiederzugeben. In Fig. ι derThe present invention is intended to enable simple perspective drawing Identify the angles at which the horizontal edges of a body to be drawn from the real horizontal direction seemingly deviate, as well as the dimensions of the vertical .and crooked (but in reality horizontal) edges to be determined and graphically to reproduce correctly. In Fig. Ι the
ίο Zeichnung ist der Apparat an sich dargestellt; Fig. 2 zeigt seine Anwendung. Er besteht aus einem halbkreisförmigen Transporteur c. In seinem Mittelpunkte ist der Halbkreis mit einem Stabe α gelenkig verbunden bzw. an diesem Stabe aufgehängt. Das eine Ende des Stabes besitzt eine Einteilung, das andere einen Handgriff. Ein Zeiger b mit entsprechender Einteilung ist an dem Halbkreise im Mittelpunkt, rechtwinklig zum Durchmesser, fest angebracht.ίο the drawing shows the device itself; Fig. 2 shows its application. It consists of a semicircular conveyor c. In its center point, the semicircle is articulated to a bar α or suspended from this bar. One end of the rod has a division, the other a handle. A pointer b with a corresponding division is firmly attached to the semicircle in the center, at right angles to the diameter.
Wird der Apparat am Handgriff des Stabes α freischwebend in der Hand gehalten, so nimmt der Transporteur durch seinen eigenen Schwerpunkt stets eine solche Lage ein, daß sein Durchmesser die wagerechte und der Zeiger b die senkrechte Richtung angibt. Man braucht dann nur mit der haltenden Hand den Stab α so zu drehen, daß das eingeteilte Ende die Richtung der zu zeichnenden Körperkante einnimmt, wie Fig. 2 zeigt. Ist dies geschehen, so wird mittels der Federn f, g der Stab α am Halbkreis festgestellt und sodann der eingestellte Winkel auf das Papier übertragen. If the device is held freely floating in the hand by the handle of the rod α , the conveyor always assumes a position due to its own center of gravity such that its diameter indicates the horizontal direction and the pointer b indicates the vertical direction. One then only needs to rotate the rod α with the holding hand so that the divided end assumes the direction of the body edge to be drawn, as FIG. 2 shows. Once this has happened, the rod α is fixed on the semicircle by means of the springs f, g and the set angle is then transferred to the paper.
Da die beiden Zeiger sowie der Durchmesser vom Drehpunkte aus in gleiche Teile geteilt sind, so ist es dem Schüler leicht, außer den betreffenden Winkeln auch die Tiefenausdehnungen in ihrem scheinbaren Verhältnis zu den senkrechten Ausdehnungen des zu zeichnenden Körpers festzustellen.Because the two pointers as well as the diameter are divided into equal parts from the pivot point are, it is easy for the pupil, in addition to the angles in question, also the depths in their apparent relationship to the vertical dimensions of what is to be drawn Body to determine.
