    Huborgan für Stangenfallhämmer.   



   Stangenfallhämmer haben sich bisher nicht in dem Masse einführen können, wie es bei ihren   mannigfache Vorzügen (konstruktive Einfachheit, Zuverlässigkeit u. dgl. ) zu erwarten gewesen wäre,   u. zw. deshalb, weil das Huborgan nicht allen Anforderungen genügte.   Ursprünglich   hat man eiserne Hubstange verwendet und ist dann bald zu hölzernen Hubstangen übergegangen. Da diese ebenfalls zahlreiche Mängel aufwiesen, ist man schliesslich dazu übergegangen, das Huborgan aus faserhaltigem, mit einem erhärtenden Bindemittel versehenem Werkstoff herzustellen oder zu überziehen. Dieser Vorschlag brachte zwar gegenüber den Huborgane aus Holz einen wesentlichen Fortschritt, weil die Gefahr des Zersplitterns od. dgl. vermieden wurde, und bedeutete auch einen Fortschritt gegenüber andern Versuchen, das Holz zu ersetzen.

   Zu einem vollen Erfolg führte jedoch auch dieses Mittel nicht, weil das Huborgan keine genügende Dauerhaftigkeit aufwies. 



   Nach eingehenden Versuchen ist es gelungen, das Huborgan, das aus faserhaltigem, mit einem erhärtenden Bindemittel versehenem Werkstoff bestand oder damit überzogen war, in einer allen Anforderungen bezüglich Dauerhaftigkeit und Festigkeit genügenden Weise herzustellen. 



   Gemäss der Erfindung wird das Huborgan oder die Belegung des Huborgans aus einem mehrschichtigen Gewebe hergestellt, dessen Schichten durch ein in unlösliche Form gebrachtes Kunstharz verbunden sind ; als Gewebe wird vorzugsweise Baumwollgewebe angewendet. 



   Praktische Erfahrungen haben gezeigt, dass dieses Huborgan eine ausserordentlich grosse Widerstandsfähigkeit gegen Abnutzung besitzt ; Splittergefahr ist vollständig ausgeschlossen und infolgedessen wird für das Huborgan eine Lebensdauer erzielt, durch die der Stangenfallhammer erst zu einer den modernen Anforderungen entsprechenden Maschine wird.

    Lifting device for drop hammers.



   Drop hammers have so far not been able to introduce themselves to the extent that would have been expected with their multiple advantages (structural simplicity, reliability, etc.), and the like. because the lifting element did not meet all requirements. Originally, iron lifting rods were used and then wooden lifting rods were soon used. Since these also had numerous deficiencies, one finally switched to producing or coating the lifting element from fiber-containing material provided with a hardening binder. This proposal did bring about a significant advance compared to the wooden lifting members because the risk of splintering or the like was avoided, and it also represented an advance compared to other attempts to replace the wood.

   However, this remedy did not lead to complete success either, because the lifting element was not sufficiently durable.



   After extensive tests, it was possible to manufacture the lifting element, which consisted of fiber-containing material provided with a hardening binding agent or was coated with it, in a manner that met all requirements with regard to durability and strength.



   According to the invention, the lifting element or the covering of the lifting element is produced from a multilayer fabric, the layers of which are connected by a synthetic resin which has been made insoluble; cotton fabric is preferably used as the fabric.



   Practical experience has shown that this lifting element has an extremely high resistance to wear; The risk of splinters is completely excluded and as a result, a service life is achieved for the lifting element, through which the drop hammer becomes a machine that meets modern requirements.
