KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Befestigung für Sägeblätter, welche ein einfaches Einspannen und zugleich ein leichtes Anspannen des Sägeblattes ermöglicht. Mittels einer einzigen Bewegung eines Excenterhebels werden beide Vorgänge .zugleich ausgeführt.The present invention is a fastening for saw blades, which is a simple Clamping and at the same time a slight tensioning of the saw blade enables. Means a single movement of an eccentric lever, both processes are carried out at the same time.
Der Gegenstand der Erfindung ist auf den beiliegenden Zeichnungen in zwei Ausführungsformen dargestellt, und zwar zeigt Fig. 1 den Befestigungskörper der Vorrichtung an dem Sägebügel in schaubildlicher Ansicht, Fig. 2 eine Abänderung desselben, Fig. 3 eine schaubildliche Ansicht des Spannhebels, Fig. 4 eine schaubildliche Ansicht der Klemmvorrichtung für das Sägeblatt. Fig. 5 bis 8 stellen An sichten der ganzen Vorrichtung vor bezw. nach Einsetzen eines Sägeblattes dar. Fig. g zeigt eine Abänderung des in Fig. 3 dargestellten Spannhebels.The object of the invention is shown in two embodiments on the accompanying drawings, namely Fig. 1 shows the Fastening body of the device on the saw frame in a perspective view, FIG. 2 a modification of the same, FIG. 3 a perspective view of the tensioning lever, FIG. 4 a Diagrammatic view of the clamping device for the saw blade. Figs. 5 to 8 represent view the whole device before BEZW. after inserting a saw blade. Fig. g shows a modification of the clamping lever shown in FIG.
Zur Befestigung der Vorrichtung am Sägebiigel dient ein Halter a, welcher mittels Schrauben c an dem Arm b des Sägebügels befestigt fet. Die Schrauben c sind, um ein Verstellen des Sägehalters α am Sägebügel zu ermöglichen, in Schlitzen 1 geführt. Der Halter α ist ferner mit einer Führung für die Klemmvorrichtung e zur Aufnahme der Säge versehen. An den durch den Zwischenraum 2 getrennten federnden Theilen, der Einspannvorrichtung e, sind Nasen 3 vorgesehen. Ein Stift f greift in bekannter Weise in den Schlitz g des Excenterhebels h ein, welcher an dem Halter vermittelst eines Stiftes 6 drehbar gelagert ist. Das andere Ende des Hebels h ist mit einem Handgriff k versehen. A holder a is used to fasten the device to the saw bow, which is fastened to the arm b of the saw bow by means of screws c. The screws c are guided in slots 1 in order to allow adjustment of the saw holder α on the saw frame. The holder α is also provided with a guide for the clamping device e for receiving the saw. Lugs 3 are provided on the resilient parts, the clamping device e, which are separated by the intermediate space 2. A pin f engages in a known manner in the slot g of the eccentric lever h , which is rotatably mounted on the holder by means of a pin 6. The other end of the lever h is provided with a handle k .
Eine zweite Befestigungsart des Excenterspannhebels an dem Sägehalter α ist in den Fig. 2 und 9 dargestellt. Der Excenterhebel trägt einen mit Schraubengewinde versehenen Stift 5, welcher in entsprechendes Gewinde 4 des Halters α eingeschraubt wird. Der Hebel h kann auch den Halter α umfassend ausgebildet sein. Es müssen dann beiderseits entsprechende Schlitze und Führungsstifte vorgesehen sein (Fig. 3, 6 und 8 punktirt angedeutet).A second type of fastening of the eccentric clamping lever on the saw holder α is shown in FIGS. The eccentric lever carries a screw-threaded pin 5 which is screwed into the corresponding thread 4 of the holder α . The lever h can also be designed to include the holder α . Corresponding slots and guide pins must then be provided on both sides (Fig. 3, 6 and 8 indicated by dotted lines).
Die Wirkungsweise der Vorrichtung ist nun folgende: Will man ein Sägeblatt einspannen, so bringt man zuerst den Excenterhebel h in die in Fig. 5 gezeichnete Stellung und legt das Blatt zwischen die federnden Backen der Klemmplatte e. Dann dreht man den Excenterhebel h in die in Fig. 7 gezeichnete Stellung. Bei dieser Drehung bewegt sich der Stift f der Klemmplatte e in dem excentrischen Schlitz des Hebels h, wodurch das Klemmstück e hochgezogen wird. Durch die Nasen 3 dieses Klemmstückes, welche beim Hochziehen des Klemmstückes e an den Seitenwänden des Führungsloches d des Halters α Widerlager finden, werden nun die federnden Backen des Stückes e zusammengeprefst, und die zwischen ihnen liegende Säge j wird zugleich ein- und angespannt. Bei der Ausführungsform, nach Fig. 2 und 9 wird nun noch das Klemmstück e durch den Gewindestift 5 in seiner Lage gesichert.The operation of the device is as follows: If you want to clamp a saw blade, you first bring the eccentric lever h into the position shown in FIG. 5 and place the blade between the resilient jaws of the clamping plate e. Then the eccentric lever h is rotated into the position shown in FIG. During this rotation, the pin moves f e of the clamping plate in the slot of the eccentric lever h, is pulled up whereby the clamping piece e. Through the lugs 3 of this clamping piece, which find abutments on the side walls of the guide hole d of the holder α when the clamping piece e is pulled up, the resilient jaws of the piece e are now pressed together, and the saw j lying between them is clamped and clamped at the same time. In the embodiment according to FIGS. 2 and 9, the clamping piece e is now secured in its position by the threaded pin 5.
