Gegenstand der Erfindung ist ein aus mehreren Teilen bestehender Grubenstempel, welcher ermöglicht, daß beim Gebrauche in der Grube gebrochene oder sich für die betreffende Verwendungsstelle zu kurz erweisende Stempel wieder verwendet werden können, so daß an Holzkosten gespart wird. Ist ein Stempel gebrochen, so werden die beiden Bruchstellen glatt abgesägt und dieseThe subject of the invention is a pit stamp consisting of several parts, which makes it possible for the pit to be broken or damaged when in use Place of use too short stamps can be used again, so that wood costs are saved. If a punch is broken, the two break points are sawn off and this one
xo Enden Ss1 mit einem Abstande von S bis 7 cm durch eiserne Laschen IZ1 wieder verbunden. Nachdem dieser Stempel an seinem ι Bestimmungsort eingebaut ist, wird er durch Eintreiben eines Keiles k zwischen den Abstand der Enden auf die erforderliche Länge und in Spannung gebracht. Hierauf wird die Verlaschung fest angezogen. Der Keil an sich ist bekannt, doch nicht in der Verbindung mit der beanspruchten Verlaschung und zu genanntem Zwecke. Als Spitzen ausgebildete Nietenköpfe im Innern der Lasche oder quer zur Längsfaser des Holzes eingepreßte Rillen in der Verlaschung dringen beim Anziehen letzterer fest ins Holz ein.xo ends Ss 1 connected again with a distance of S to 7 cm by iron straps I Z 1 . After this punch has been installed at its destination, it is brought to the required length and tensioned by driving in a wedge k between the distance between the ends. The lashing is then tightened firmly. The wedge itself is known, but not in connection with the claimed lashing and for the stated purpose. Rivet heads designed as points in the interior of the flap or grooves pressed into the lashing transversely to the longitudinal fiber of the wood penetrate firmly into the wood when the latter is tightened.
Das gleiche Verfahren ist anwendbar, wenn zur Stützung des Gebirges nicht genügend ■lange Stempel vorhanden sind.The same procedure can be used if insufficient to support the mountain range ■ long stamps are present.
Ein derartiger Stempel ist bequemer einzubauen und stört hierbei das hängende Gebirge nicht. Beim Bergeversatz ist er leichter zurückzugewinnen.Such a stamp is more convenient to install and disturbs the hanging mountains not. It is easier to recover when moving mountains.
