  Vorrichtung zum Spalten von Baumstrünken. 



   Die bisher bekannten Vorrichtungen zum Spalten von Baumstrünken erfordern viel Menschenkraft und Zeit. Zweck der vorliegenden Erfindung ist, diesem Übelstande abzu- helfen. Das Spalten erfolgt daher nach bekannter Art mittels eines Keiles, doch ist dieser erfindungsgemäss drehbar mit einer Schraubenspindel verbunden, deren Mutter in einer Querstrebe unbeweglich gelagert ist, welche mittels Ketten mit dem Baumstrunk fest verbunden ist, um der Schraubenspindel und dadurch auch dem Keile eine feste Stütze zu bieten ; durch Verdrehen der Spindel dringt der Keil in den Banmstrunk ein und spaltet ihn. 



   Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes : Fig. 1 zeigt die Vorrichtung in Vorderansicht, Fig. 2 ist ein lotrechter Schnitt. 



   Auf zwei Traversen   1,   11 ist eine Büchse 2 für die Mutter   8   einer Schraubenspindol 4 befestigt. Am oberen Ende hat die Spindel einen Kopf 5, der seitlich zwei Gabeln   fi.     6''trägt,   in denen Handhaben 7. 7' drehbar befestigt sind. Das untere Ende der Schraubenspindel 4 samt dem fest auf ihr aufgesetzten Ring   14   ist mittels der auf 
 EMI1.1 
 der oberen Hälfte einen grösseren Winkel miteinander einschliessen als in der unteren. damit der Baumstrunk rascher gespalten werde. 



   Zum Befestigen der Vorrichtung am Baumstrunk dienen die beiden Ketten 9. 10. die gegen das Abgleiten von den Traversen 1. 1' durch Winkeleisen 11, 12 gesichert sind. Durch Drehen der Schraubenspindel mittels der Handhaben 7. 7'wird der Keil in den   Baumstrunk   eingetrieben, so dass dieser gespalten wird.

  Device for splitting tree stumps.



   The previously known devices for splitting tree stumps require a lot of manpower and time. The purpose of the present invention is to remedy this drawback. The splitting is therefore carried out in a known manner by means of a wedge, but according to the invention this is rotatably connected to a screw spindle, the nut of which is immovably mounted in a cross strut, which is firmly connected to the tree trunk by chains, around the screw spindle and thus also the wedge To provide support; by turning the spindle, the wedge penetrates the banm trunk and splits it.



   The drawing shows an embodiment of the subject matter of the invention: FIG. 1 shows the device in front view, FIG. 2 is a vertical section.



   A bushing 2 for the nut 8 of a screw spindle 4 is attached to two cross members 1, 11. At the upper end, the spindle has a head 5 which has two forks at the side. 6 '', in which handles 7. 7 'are rotatably attached. The lower end of the screw spindle 4 together with the ring 14 firmly attached to it is on by means of the
 EMI1.1
 the upper half form a larger angle with each other than in the lower half. so that the tree trunk is split more quickly.



   The two chains 9, 10, which are secured against sliding off the cross-bars 1, 1 ′ by angle irons 11, 12, are used to fasten the device to the tree trunk. By turning the screw spindle by means of the handle 7, 7 ', the wedge is driven into the tree trunk so that it is split.
