Description
485(520485 (520
Bei der bisher angewandten Art des Fällens von Baumstämmen, besonders solcher von großer Höhe, besteht der Nachteil darin, daß die Bäume oberhalb des Fallkerbes beim Umstürzen der Länge nach aufspringen. Hierdurch wird gerade der wichtigste Teil des Stammes, nämlich derjenige von größtem Durchmesser und größter Astreinheit betroffen und der Stamm verliert naturgemäß ίο durch derartige Sprünge — die vielfach eine beträchtliche Länge erreichen — ganz bedeutend an Wert oder wird für einzelne Verwendungszwecke unbrauchbar, so daß die schönsten Abschnitte als Brennholz statt als Nutzholz verwendet werden müssen.With the previously used method of felling tree trunks, especially those of great height, the disadvantage is that the trees above the felling notch when Overturning, jumping up lengthways. This is the most important part of the Trunk, namely the one with the largest diameter and the greatest clearness of branches affected and the trunk naturally loses ίο through such jumps - often one Reach considerable length - quite significant in value or used for individual purposes unusable, so that the most beautiful sections have to be used as firewood instead of timber.
Durch vorliegende Erfindung wird nun eine Vorrichtung geschaffen, welche diesen Mißstand dadurch beseitigt, daß eine einfache Spannvorrichtung um den Stamm gelegt wird und diesen durch konzentrischen Umfangsdruck vor dem Springen oder Aufspalten beim Fällen bewahrt.The present invention now provides an apparatus which overcomes this deficiency eliminated by placing a simple jig around the trunk and using concentric circumferential pressure to keep it from cracking or splitting during felling.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes darge- *5 stellt, und zwar zeigt:The drawing shows an exemplary embodiment of the subject matter of the invention. * 5 represents:

Abb. 3 Spannvorrichtung an dem zu fällenden Baumstamm.Fig. 3 Clamping device on the tree trunk to be felled.
Die Vorrichtung zur Verhütung des Springens von Baumstämmen beim Fällen besteht aus einer Spannwinde α und einer Kette b, welche um den Stamm c oberhalb des zum Fällen erforderlichen Fallkerbes und Sägeneinsohnittes d (Abb. 3) herumgelegt wird, sobald der Fallkerb eine gewisse Tiefe erreicht hat. Das eine Kettenende e ist am Kopf / der Spannwinde befestigt, das freie Ende der Kette wird nach dem Umlegen um den Stamm mit einem entsprechenden Glied in den Haken' g der Spann winde eingehängt, worauf die Spindel h mittels eines Steckschlüssels i angezogen wird, bis sich die Kette b fest um den Stamm angelegt hat. Treten Unterschneidungen an einem Stammumfang auf, so werden, solche zweckmäßig durch Einlegen von Klötzen ausgefüllt, um auch an den hohl liegenden Stellen der Kette einen nach dem Zentrum des Stammes wirkenden Druck zu erzielen. Um ein Verschieben oder Abspringen der Spannvorrichtung zu verhindern, kann diese durch Eisenkloben am Stamm angeheftet werden. Die Kette läßt sich je nach Bedarf, entsprechend dem Stammumfang, mit auswechselbaren Stücken ausstatten.The device for preventing tree trunks from jumping when felling consists of a tensioning winch α and a chain b, which is placed around the trunk c above the felling notch and saw unit d (Fig. 3) as soon as the felling notch has reached a certain depth . One end of the chain e is attached to the head / the tensioning winch, the free end of the chain is hung after being folded around the trunk with a corresponding link in the hook 'g of the tensioning winch, whereupon the spindle h is tightened using a socket wrench i until the chain b is firmly attached to the trunk. If undercuts occur on the circumference of the trunk, these are expediently filled by inserting blocks in order to achieve a pressure acting towards the center of the trunk even at the hollow points of the chain. To prevent the clamping device from shifting or jumping off, it can be attached to the trunk using iron clamps. The chain can be equipped with interchangeable pieces as required, depending on the size of the trunk.
