KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen verstellbaren Winkel, mit dem bezweckt wird, die verstellbare Reißschiene, deren umständliches, unzuverlässiges Handhaben bekannt ist, zu ersetzen und den lästigen Gebrauch mehrerer fester Winkel zu umgehen.The invention relates to an adjustable angle with the aim of the adjustable To replace tear bar, whose cumbersome, unreliable handling is known and avoid the cumbersome use of multiple fixed angles.
In der Zeichnung ist der Gegenstand in den Fig. i, 2 und 3 dargestellt.In the drawing, the object is shown in FIGS. 1, 2 and 3.
Ein Winkelstück α sitzt mittels Nutenführung d und Feder e auf einer aus einem zweiten Winkelstück c auslaufenden kreisförmigen Scheibe b. Diese Scheibe b ist an einer Stelle zur Aufnahme der Sprungfeder e gerade abgeschnitten. Die beiden Winkelstücke haben jedes für sich ungleiche Schenkel, jedoch sind sie derart zusammengesetzt, daß entsprechende gleiche Schenkel zusammenfallen können. Beim Zeichnen wird der Winkel an der Reißschiene angeschlagen und ist auf beiden Seiten brauchbar wie der feste Winkel, weil keine Verbindungsteile aus der Winkelebene vorstehen. Durch Drehen des Winkels a (Fig. 2) werden neue Winkel gebildet, so daß bei einer Drehung um 45 ° sämtliche Winkel bis i8o° eingestellt werden können.An angle piece α is seated by means of a groove guide d and a tongue e on a circular disc b extending from a second angle piece c. This disk b is just cut off at a point for receiving the spring e. The two elbows each have unequal legs, but they are put together in such a way that corresponding equal legs can coincide. When drawing, the angle is posted on the tear bar and can be used on both sides like the fixed angle, because no connecting parts protrude from the angle plane. By turning the angle a (Fig. 2) new angles are formed, so that with a turn of 45 ° all angles up to 180 ° can be set.
