KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Von den bekannten Rahmenspannern, bei denen die Rahmenteile einer Ecke durch drehbare, von Federn auseinander gehaltene Backen von innen gegen rechtwinklige Anschlage mittels eines Exzenterhebels gepreßt werden, unterscheidet sich der Erfindungsgegenstand durch die Ausbildung der Sperrvorrichtung für den frei verschiebbaren Spannhebelträger. From the known frame tensioners, in which the frame parts pass through a corner rotatable jaws held apart by springs from the inside against right-angled stops are pressed by means of an eccentric lever, the subject of the invention differs in the design of the locking device for the freely movable clamping lever carrier. ίο Fig. ι der Zeichnung zeigt die Spannvorrichtung im Querschnitt, Fig. 2 im Grundriß, Fig. 3 im Längsschnitt; Fig. 4 zeigt die Keile im Grundriß, Fig. 5 und 6 die, Ausbildung und Anordnung der Feder i. FIG. 1 of the drawing shows the clamping device in cross section, FIG. 2 in plan view, FIG. 3 in longitudinal section; Fig. 4 shows the wedges in plan, Fig. 5 and 6, the design and arrangement of the spring i. Die zugeschnittenen Leisten r (Fig. 2) werden in den Rahmen α gelegt. Mittels des Exzenterhebels f wird sodann der beiderseits geführte Spannhebelträger d an die Leisten herangeschoben und der Exzenterhebel f nach oben bewegt, so daß infolge der Exzentrizität die Keile h durch den Keil g, der mittels Zuglaschen e mit dem Exzenterhebel verbunden ist, gegen die seitlichen Führungen gepreßt werden und hierdurch ein fester Stützpunkt für das Zusammendrücken der Leisten r mittels der Spannbacken b erzielt wird. Die an dem Spannhebel träger d angeordnete Feder i (Fig. 5 und 6), an welche sich die Ansätze der Keile h stützen, verhindert einen töten Gang und ein Wegrutschen der Keile.The cut strips r (Fig. 2) are placed in the frame α . By means of the eccentric lever f , the clamping lever support d , which is guided on both sides, is then pushed up to the bars and the eccentric lever f is moved upwards, so that due to the eccentricity, the wedges h through the wedge g, which is connected to the eccentric lever by means of tension straps e , against the lateral guides are pressed and thereby a firm support point for the compression of the strips r by means of the clamping jaws b is achieved. The spring i (FIGS. 5 and 6) arranged on the tensioning lever support d , on which the lugs of the wedges h are supported, prevents dead gear and the wedges from slipping. Ein weiteres Drehen des Exzenterhebels f schiebt den Spannhebelträger d mit den an ihm angelenkten gezahnten Backen b gegen den inneren Falz der Rahmenleisten r und drückt diese mit ihren Schnittflächen gegeneinander. In dieser Lage bleibt der Exzenterhebel f, und die Leisten bleiben unter beliebigem Druck zum Leimen gegeneinandergepreßt. Ein Rückwärtsdrehen des Exzenterhebels f löst die Backen b sofort, und die geleimten Leisten können bequem herausgenommen werden.A further rotation of the eccentric lever f pushes the clamping lever carrier d with the toothed jaws b hinged to it against the inner fold of the frame strips r and presses them against one another with their cut surfaces. The eccentric lever f remains in this position, and the strips remain pressed against one another under any pressure for gluing. A backward rotation of the eccentric lever f releases the jaws b immediately, and the glued strips can be easily removed. In gelöster Stellung drückt die Spannfeder c, wie bereits bekannt, die gezahnten Backen b wieder an die Führungen.In the released position, the tension spring c, as already known, presses the toothed jaws b back against the guides.
