Description
Beim Fällen und Trennen von Baumstämmen sowie beim Trennen von Hölzern, die durch Windwurf unter Spannung liegen, geht vielfach eine große Menge wertvollen Nutzholzes dadurch verloren, daß solches dabei aufspringt (spaltet, schlenzt).When felling and separating tree trunks and when cutting wood that are under tension from windthrow, a large amount of valuable timber is often lost lost by the fact that it pops up (splits, flaps).
Die bisher zur Anwendung kommenden Vorrichtungen ähnlicher Art haben gegenüber dem Eriindungsgegenstand den Nachteil, daß sie einen zu großen Aufwand an Baustoffen bedingen und somit ein verhältnismäßig großes Gewicht erfordern, und zwar hauptsächlich deshalb, weil bei solchen Vorrichtungen schwere Ketten verwendet werden, welche die Vorrichtung nicht nur verteuern, sondern in erster Linie unhandlich gestalten.The previously used devices of a similar type have opposite the subject of the invention has the disadvantage that it involves too much building materials and thus require a relatively large weight, mainly because heavy chains are used in such devices, which the Device not only make it more expensive, but primarily make it unwieldy.
Dieser Nachteil wird beim Erfindungsgegenstand dadurch behoben, daß an Stelle schwerer Ketten ein Stahltaii zur Anwendung kommt, das durch geringes Gewicht und leichte Handhabung wesentlich betriebssicherer ist und einen niedrigen Anschaffungspreis erfordert. Dieses Stahltau weist auch keine eingellochtenen Endschlaufen auf, die das Tau wesentlich verteuern würden.This disadvantage is eliminated in the subject matter of the invention that in place heavy chains a steel part is used, which is due to its low weight and easy handling is much more reliable and a low purchase price requires. This steel rope also does not have any braided end loops that allow the Would make dew much more expensive.
in der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigenin the drawing is an embodiment of the subject invention shown, namely show
Abb. ι Stammholzspaltverhüter in der Ansieht, Fig. Ι A view of the splitting of logs,
Abb. 2 derselbe im Querschnitt,
Abb. 3 derselbe von oben gesehen,
Abb. 4 und 5 Schema für die Einziehung des Stahltaues in zweierlei Art.
Um den Baumstamm α ist ein Stahltau b
herumgelegt, dessen Enden c und d in zwei in einer Grundplatten geführten Schlitten /
und g eingeschoben und hier durch die Klemmschrauben h festgehalten sind, welche
eine Einbuchtung im Stahltau hervorrufen. Der die Stahltauenden c und d aufnehmende ·
Ansatz der Schlitten / und g ist je in einem in der Grundplatten befindlichen Schlitz/ geführt.
Die Schlitten / und g besitzen Linksund Rechtsgewinde, in welche die Gewinde
der Spindel k hineinpassen. Die Spindel k
besitzt in deren Mitte einen in der Grundplatte e drehbar^eingelassenen Kopf/, dessen
Öffnungen m zum Einstecken eines Domes dienen, durch den die Spindel k gedreht werden
kann. An der Unterseite der Grundplatte e befinden sich drei Verstärkungsrippen,
deren Hochkante entsprechend der Rundung des Baumstammes α eingebuchtet ist.Fig. 2 the same in cross section,
Fig. 3 the same seen from above,
Fig. 4 and 5 Scheme for drawing in the steel rope in two different ways.
A steel cord b is wrapped around the tree trunk α , the ends c and d of which are inserted into two slides / and g guided in a base plate and are held here by the clamping screws h , which create an indentation in the steel cord. The attachment of the carriages / and g receiving the steel rope ends c and d is each guided in a slot / located in the base plate. The carriages / and g have left-hand and right-hand threads into which the threads of the spindle k fit. The spindle k has in its center a head / rotatably embedded in the base plate e , the openings m of which are used to insert a dome through which the spindle k can be rotated. On the underside of the base plate e there are three reinforcing ribs, the upper edge of which is indented according to the curve of the tree trunk α.
Ein wesentlicher Vorteil des Spaltverhüters nach der Erfindung gegenüber ähnlichen Vorrichtungen besteht darin, daß hierbei ein Stahltau verwendet wird, welches keine Endschlaufen haben muß und deshalb in jeder Länge angewandt werden kann. Ein weiterer großer Vorteil dieser Vorrichtung ist sein geringes Gewicht.A major advantage of the gap preventer according to the invention over similar ones Devices is that here a steel rope is used, which does not have to have end loops and can therefore be used in any length. A Another great advantage of this device is its low weight.
Durch zwei dünne Ketten kann die Vorrichtung am Baumstamm angehängt werden.The device can be attached to the tree trunk using two thin chains.
