KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine eiserne Hohlstütze, die vorzugsweise als Grubenstempel Verwendung finden soll. In ihrem Hohlraum sind Ringe oder Scheiben aus Metall, Holz ο. dgl. aufeinandergeschichtet, zu dem Zwecke, die Knickfestigkeit der Stütze nach Bedarf zu erhöhen. Wird der Grubenstempel aus zwei ineinanderschiebbaren Teilen zusammengesetzt, so wird zwischen dem Boden des inneren. Stempelteils und dem des äußeren eine Füllmasse aus Metallkugeln eingebracht, die aus einer unteren Öffnung im Bedarfsfalle austritt, ohne daß sie, wie dies bei Sandfüllungen bekannter Art, die zerrieben oder zusammengeballt werden, der Fall ist, eine Veränderung erleiden, die das Nachgeben des inneren Stempelteiles behindern könnte.The invention relates to an iron hollow support, which is preferably used as a pit stamp Should be used. In its cavity there are rings or discs made of metal, wood ο. Like. Stacked, for the purpose of increasing the buckling strength of the support as required raise. If the pit punch is made up of two parts that can be pushed into one another, so will between the bottom of the interior. Stamp part and that of the outer a filling compound introduced from metal balls, which emerge from a lower opening if necessary, without them, as is the case with sand fillings of a known type, which are crushed or agglomerated will, is the case, suffer a change that causes the yielding of the inner part of the stamp could hinder.
In der Zeichnung zeigtIn the drawing shows
Fig. ι einen derartigen Grubenstempel teilweise im Längsschnitt und teilweise in Ansicht. Fig. Ι such a pit punch partially in longitudinal section and partially in view.
Fig. 2 ist ein wagerechter Schnitt nach Linie 1-1 in Fig. 1.FIG. 2 is a horizontal section along line 1-1 in FIG. 1.
Fig. 3 zeigt eine zweite Ausführungsform des Erfindungsgegenstandes, teilweise im Schnitt, teilweise in Ansicht.Fig. 3 shows a second embodiment of the subject matter of the invention, partially in section, partly in view.
Der in Fig. 1 und 2 dargestellte Stempel besteht aus den beiden teleskopartig ineinanderschiebbaren Rohren α und b. Ringe c aus Metall, Holz oder sonstigem Baustoff sind in dem Rohr α aufeinandergeschichtet, das durch die Verschlußstücke d und e an den Enden abgeschlossen und ferner am oberen Ende durch eine Kappe / abgedeckt wird.The punch shown in Fig. 1 and 2 consists of the two telescoping tubes α and b. Rings c made of metal, wood or other building material are stacked in the tube α , which is closed at the ends by the closure pieces d and e and furthermore covered at the upper end by a cap /.
Das Rohr b ruht mit seinem unteren Ende auf einer Platte g, die eine Anzahl der Ringe h trägt. Auf dem obersten dieser Ringe ruht eine zu einem Hahn ausgebildete Scheibe i. Zwischen dieser und dem unteren Ende des Rohres « läßt ,man einen Raum / frei, der mit Metallkugeln 0 ausgefüllt und unten durch den Zwischenboden i abgeschlossen wird.The tube b rests with its lower end on a plate g which carries a number of rings h. On the uppermost of these rings rests a disk i designed as a cock. A space / is left between this and the lower end of the tube, which is filled with metal balls 0 and closed at the bottom by the intermediate floor i .
Um den Stempel ans einer bestimmten Stellung leicht zu entfernen, genügt es, den Hahn p im Zwischenboden i zu öffnen. Die in dem Räume j enthaltenen Metallkugeln treten alsdann in den durch die Ringe h eingeschlossenen, unter der Scheibe i liegenden Raum k ein, worauf sich der innere Stempelteil a, c abwärts bewegt.In order to easily remove the stamp ans from a certain position, it is sufficient to open the valve p in the intermediate floor i. The metal balls contained in the space j then enter the space k enclosed by the rings h and lying under the disk i, whereupon the inner punch part a, c moves downwards.
Der Stempel nach Fig. 3 ist als eine einfache, mit dem Sockel η und dem Haupt m versehene Säule ausgebildet. Auch hier sind in den Hohlraum Ringe I aus Metall, Holz oder ähnlichem Baustoff eingelegt, um nach Bedarf die Knickfestigkeit des Stempels zu erhöhen. Eine solche Säule läßt sich naturgemäß auch auf anderen Gebieten als dem' des Grubenbaues, beispielsweise im Hochbau, als Stütze verwenden.The stamp according to FIG. 3 is designed as a simple column provided with the base η and the main m. Here, too, rings I made of metal, wood or similar building material are inserted into the cavity in order to increase the buckling strength of the stamp as required. Such a column can naturally also be used as a support in fields other than mining, for example in building construction.
