Description

Quets stückö zwischen dem Ober- und Unterteil eines nachgiebigen eisernen Grubenstempels. Nach der Erfindung unterscheiden sich die Quetschstücke zwischen dem Ober- und Unterteil eines nachgiebigen eisernen Grubenstempels gegenüber den Quetschstücken, die unsichtbar oder nur zum Teil sichtbar -und mangelhaft zugänglich im Innern des Stempelunterteils untergebracht sind und von dem in sie eindringenden Oberteil zerschnitten werden, dadurch, daß sie in Gestalt von mehreren den Stempelunterteil umgebenden Ringen zwischen je einem Fußstück der beiden Stempelteile angeordnet sind. In diesem Fall ist man in der Bemessung der Quetschstücke nicht an die Abmessungen der Stempelquerschnitte gebunden, so daß weniger große Quetsclistücke verwendet werden können; es werden die Ringe, unbeeinflußt von der Querschnittsform der Stempelteile, zwischen den Fußstücken lediglich gequetscht, aber nicht zerschnitten, und sie liegen frei sichtbar und allseitig zugänglich, so daß das Maß ihrer Quetschung auf den ersten Blick festzustellen ist und zwecks Raubens des Stempels erforderlichenfalls ein Ring leicht entfernt oder zum Teil entfernt werden kann.Quetsstückö between the upper and lower part of a flexible iron pit die. According to the invention, the squeeze pieces differ between the upper and lower parts of a resilient iron pit punch compared to the squeeze pieces, which are invisible or only partially visible and inadequately accessible in the interior of the lower punch part and are cut by the upper part penetrating into them, as a result, that they are arranged in the form of several rings surrounding the lower part of the punch between each foot piece of the two punch parts. In this case, the dimensions of the pinch pieces are not tied to the dimensions of the punch cross-sections, so that pinch pieces that are less large can be used; the rings, unaffected by the cross-sectional shape of the stamp parts, are only squeezed between the foot pieces, but not cut, and they are freely visible and accessible from all sides, so that the extent of their squeezing can be determined at first glance and, if necessary, for the purpose of stealing the stamp Ring can be easily removed or partially removed.

Die Zeichnung veranschaulicht den Stempel als ein Ausführungsbeispiel in Ansicht. Zwischen dem tellerförmigen Fuß c des beispielsweise aus einem Rohrstück bestehenden Stempeloberteils a und dem gleichfalls tellerartigen Fußstück d des in den Oberteil einschiebbaren, beispielsweise äleichfalls aus einem Rohrstück bestehenden Stempelunterteils b sind als Quetschstücke dienende Ringe e aus Holz oder aus ähnlichen Stoffen angeordnet, welche unter dem Druck des Gebirges zusammengedrückt werden.The drawing illustrates the stamp as an embodiment in view. Between the plate-shaped foot c of the upper punch part a, which consists for example of a pipe piece, and the likewise plate-like foot piece d of the lower punch part b, which can be pushed into the upper part, e.g. Pressure of the mountains are squeezed.
