Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Schutzvorrichtung für Kreissägen unterscheidet sich von der im Haupt-Patent beschriebenen Ausführung im wesentlichen dadurch, dafs die fünf Schilder b hivu desselben nunmehr durch die beiden in D gelenkig mit einander verbundenen Schilder B ersetzt sind, welche einerseits dieselbe Wirkung ausüben, andererseits eine Verriegelung des Systems möglich machen. Um sie dazu zu befähigen, ist an dem Gelenkbolzen des Armes m und Gitters I eine Rolle R angebracht, welche in der Ursprungslage (Fig. 1) die zwischen denselben Verticalebenen befindlichen Schilder H und B bezw. deren Nase so zusammenhält, dafs sie sich bei E berühren. Wird nun das Kurbelgetriebe mlk durch das bei m eingeschobene Werkstück aufgedreht, so wälzt sich die Rolle R an der gekrümmten Unterkante des Schildes H entlang, hält dabei die Schilder B und H weiter zusammen und dreht sie, als ob sie ein einziges Stück wären, um den Punkt c so hoch' auf (Fig. 4), dafs das Werkstück unter ihnen fortschreiten kann.The present protective device for circular saws differs from the design described in the main patent essentially in that the five shields b hivu of the same are now replaced by the two shields B articulated to one another in D, which on the one hand have the same effect and on the other hand a locking make the system possible. To enable them to do so, a roller R is attached to the hinge pin of the arm m and grid I , which in the original position (Fig. 1) respectively the signs H and B located between the same vertical planes. whose nose holds together so that they touch at E. If the crank mechanism mlk is now opened by the workpiece inserted at m , the roller R rolls along the curved lower edge of the shield H , holding the shields B and H together and turning them as if they were a single piece the point c so high '(Fig. 4) that the workpiece can advance below them.

Sobald die Hinterkante desselben unter den Gelenkhebeln durchgegangen ist, fällt das letztere sofort herab. Gleichzeitig beginnen auch die Schilder H und B ihre Abwärtsbewegung, während deren sie aus einander gehen und dem Fortschreiten des Werkstückes entsprechend den äufseren Umfang desselben umhüllen. Die gröfste Auseinandersperrung beider Schilder wird erreicht, wenn der an dem Schild H befestigte Stift F bei der Abwärtsdrehung des ersteren auf das Gitter I trifft (Fig. 5). Bei der weiteren Bewegung der Schilder gleitet Stift F auf dem Gitter I abwärts und leitet dadurch die Spitze des Schildes H auf die Rolle R, so dafs beide allmälig wieder zusammengehende Schilder endlich die Ursprungslage annehmen. In dieser ruht Stift F auf dem Gitter / auf und giebt, namentlich wenn kein Sägetisch vorhanden ist, den Schildern J5 und H durch Verriegelung mit den Gelenkhebeln klmn denjenigen Halt gegen einen von oben auf sie ausgeübten Druck, der zur Sicherheit auf die Schutzvorrichtung fallender Personen erforderlich ist, während bei den Schildern b h iv u des Haupt-Patentes im gegebenen Falle ein Auseinanderschieben derselben leicht eintreten kann.As soon as the rear edge of the same has passed under the articulated levers, the latter falls down immediately. At the same time, the shields H and B also begin their downward movement, during which they move apart and envelop the outer circumference of the same as the workpiece progresses. The greatest separation of the two shields is achieved when the pin F attached to the shield H hits the grid I when the former is rotated downwards (FIG. 5). With the further movement of the signs, pin F slides downwards on the grid I and thereby guides the tip of the sign H onto the roller R, so that both signs, which gradually come together again, finally assume their original position. In this, pin F rests on the grid / and, especially when there is no saw table, gives the signs J5 and H by locking with the articulated levers that hold against a pressure exerted on them from above, which is necessary for the safety of persons falling on the protective device is required, while with the signs bh iv u of the main patent in the given case a pushing apart of the same can easily occur.

Bei Werkstücken von geringer Schnitthöhe ist die Anbringung des Schildes H entbehrlich. In solchen Fällen genügt ein einziges Schild von der Form der Schilder B und H zusammengenommen, welches mit dem Stift F versehen ist; aufserdem kann der Stift F durch den am Gestell α befestigten Stift T ersetzt werden, gegen den sich der Gegengewichtshebel in der Ursprungslage lehnt.In the case of workpieces with a low cutting height, the attachment of the plate H is not necessary. In such cases, a single plate of the shape of the plates B and H taken together, which is provided with the pin F , is sufficient; In addition, the pin F can be replaced by the pin T attached to the frame α , against which the counterweight lever leans in the original position.
