Description
Vorrichtung zum Anpressen der Schienen oder Eckwinkel zum Zusammenhalten von Siebrahmen bei Plansichtern und ähnlichen Rahmenkästen. Es ist bekannt, daß zum Zusammenhalten von Rahmenkästen, z. B. von Siebrahmen bei Plansichtern Winkeleisen dienen, die durch Anziehen von Spannschrauben die einzelnen Rahmen in einer Richtung zusammenpressen. Die vorliegende Erfindung hat den Zweck, diese Eckwinkel oder Winkelschienen nicht nur als Spannanker für das Zusammenhalten der einzelneu Rahmen zu benutzen, sondern sie auch fest an den Rahmenkasten anzuschließen. Ausfübrungsforinen, mit denen dieser Zweck erreicht werden kann, sind in ,r1.er Zeichnung dargestellt.Device for pressing the rails or corner brackets to hold them together of sieve frames in plansifters and similar frame boxes. It is known that for holding frame boxes together, e.g. B. of screen frames in plan sifters angle iron serve, which by tightening the tensioning screws, the individual frames in one direction press together. The present invention has the purpose of these corner brackets or angle rails not only to be used as a tension anchor for holding the individual frames together, but also to attach them firmly to the frame box. Execution forums, with which this purpose can be achieved are shown in, r1.er drawing.
In :1@bb. i bis 3 ist eine solche Vorrichtung in Vorder- und Seitenansicht sowie im Grundriß dargestellt. Die Eckschiene a trägt hiernach oben und unten Backen b, welche an ihren Seitenflächen mit schrägen Schlitzen c versehen sind, in denen Führungsbolzen der Spannimitter d laufen. Die 'Muttern d werden durch die Spannschrawbee nach oben oder nach unten angezogen. Da jede Spannschraube e eine feste Führung hat und sich mit der 'Mutter nicht seitlich bewegen kann, so wird sich der Eckwinkel beim Anziehen der Mutter durch die schräge Anordnung der Schlitzführung c seitlich nach dem Rahmenkasten zu bewegen müssen. Dieses bewirkt, daß sich der Eckwinkel fest anpreßt und die Rahmen nun in der seitlichen wie auch in der Höhenrichtung fest eingespannt sind.In: 1 @ bb. i to 3 is such a device in front and side views as well as shown in the plan. The corner rail a carries cheeks up and down b, which are provided on their side surfaces with inclined slots c in which The guide bolts of the tensioning limiter d run. The 'nuts d are through the Spannschrawbee tightened up or down. Since each clamping screw e a fixed guide and cannot move sideways with the mother, the corner bracket will be when tightening the nut due to the inclined arrangement of the slot guide c laterally need to move after the frame box. This causes the corner angle pressing firmly and the frame now in the lateral as well as in the vertical direction are firmly clamped.
Es ist nicht umbedingt notwendig, d'aß deichzeitig unten und oben derartige Spannvorrichtungen angeordnet sind, sondern es genügt schon eine solche Vorrichtung auf einer Seite, z. B. oben, während dann unten die Schiene mit einem Scharnier oder Haken in Üsen o. dgl. mehr befestigt sein kann.It is not absolutely necessary to have it at the bottom and at the top such clamping devices are arranged, but it is sufficient such Device on one side, e.g. B. above, while then below the rail with a Hinge or hook in Üsen o. The like. Can be attached more.
Abb. d. zeigt den Grundriß einer gleichen Vorrichtung, jedoch mit der Abänderung, daß der Winkel a. in diagonaler Richtung auf beide Siebkästenwände angedrückt wird.Fig. D. shows the plan of the same device, but with the modification that the angle a. in a diagonal direction on both screen box walls is pressed.
Abb. 5 zeigt eine weitere Abänderung der Anpreßvorrichtung des Winkels oder der Schiene a, in der Weise, daß die Schraubeninutter d eine schräge Fläche besitzt, an der ein Bolzen f, der mit der Schiene a fest verbunden ist, gleitet. Durch Anziehen der Mutter d wird der Bolzen f auf die Schiene a wirken und wird sich diese dadurch ebenfalls an den Kasten anpressen.Fig. 5 shows a further modification of the pressing device of the angle or the rail a, in such a way that the screw nut d has an inclined surface on which a bolt f, which is firmly connected to the rail a, slides. By tightening the nut d , the bolt f will act on the rail a and this will also press itself against the box.
