CARL BARTELS und OTTO BARTELS in SCHWAAN, Meckl.CARL BARTELS and OTTO BARTELS in SCHWAAN, Meckl.

Einstellbares Kurvenlineal. Patentiert im Deutschen Reiche vom 11. März 1908 ab.Adjustable curve ruler. Patented in the German Empire on March 11, 1908.

Das den Gegenstand der Erfindung bildende Kurvenlineal hat die Eigenschaft, sich in beliebige Kurven biegen zu lassen und in dieser Lage zu verharren.The curve ruler forming the subject of the invention has the property of to bend in any curve and to remain in this position.

Das Kurvenlineal besteht aus der Schiene a, der Schiene b, welche parallel zur Schiene a ist, und einer Anzahl gebogener Federn c; sämtliche Teile sind aus Stahl hergestellt. Die Federn c sind an der Schiene α rechtwinklig aufgenietet und umklammern mit ihren Enden mit Spannkraft die Schiene b, jedoch so, daß ein Hin- und Herschieben der Schiene b möglich ist.The curve ruler consists of the rail a, the rail b, which is parallel to the rail a , and a number of curved springs c; all parts are made of steel. The springs c are riveted at right angles to the rail α and clasp the rail b with their ends with tensioning force, but in such a way that the rail b can be pushed back and forth.

Biegt man nun das Lineal, wie in Fig. ι ersichtlich, zu einer Kurve, so findet durch eine Verschiebung der Schienen α und b ihrer Längsrichtung nach eine Veränderung in ihrer Lage statt. In dieser gegenseitigen Lage verharren die Schienen infolge des Druckes der Federn c auf die Schiene b. If one now bends the ruler, as can be seen in FIG. 1, to form a curve, a change in their position takes place by shifting the rails α and b in their longitudinal direction. The rails remain in this mutual position as a result of the pressure of the springs c on the rail b.
