Description

AISERLICHESEVERYTHING

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Wagenschere, deren Bäume aus nahtlosen Stahlrohren hergestellt sind. Um bei diesen Scheren die gegen Knickung oft stark beanspruchten Enden der Bäume zu verstärken und gleichzeitig eine verjüngte Form bei geschlossenem wesentlich kreisförmigem Querschnitt zu erzielen, wird nach der Erfindung in dem Rohrende eine nach innen gerichtete, zum Ende hin entsprechend der Verkleinerung des Durchmessers an Höhe zunehmende Rippe erzeugt.The invention relates to a trolley shears, the trees of which are made from seamless steel tubes are. Around the ends of these scissors, which are often heavily stressed against kinking Reinforce the trees while maintaining a tapered shape when closed significantly To achieve a circular cross-section, according to the invention in the pipe end is an inwardly directed, towards the end accordingly as the diameter decreases, the rib increases in height.

In der Zeichnung ist eine Ausführungsform als Beispiel dargestellt. Die Fig. ι und 2 zeigen eine nach der Erfindung hergestellte Wagenschere in Ansichten und im Schnitt. Die Fig. 3 zeigt einen Schnitt durch den geraden Teil eines Scherenbaumes in etwas größerem Maßstabe, und in den Fig. 4 und 5 ist die Bildung des verjüngten Teils durch Herstellung einer Rippe dargestellt. Jeder der Scherenbäume α und b besteht zweckmäßig aus einem selbständigen Rohr, in dessen geraden Teil von der Rückseite her in bekannter Weise eine Holzeinlage c zur Verstärkung eingeschoben ist, bevor das das Auge d tragende Endstück e eingesetzt wurde. Dieses Endstück wird durch einen Niet f mit dem Rohr verbunden. Der einzelne Scherenbaum besteht aus einem zylindrischen Rohr, in dem an den Enden aus der Wand eine nach innen stehende Rippe g gebildet ist, die nach dem Ende hin an Höhe zunimmt. Die Scherenenden bestehen somit aus nahtlosem Rohr, sind aber wesentlich verstärkt und bei geschlossenem kreisförmigen Querschnitt verjüngt.In the drawing, an embodiment is shown as an example. Figs. Ι and 2 show a carriage scissors produced according to the invention in views and in section. Fig. 3 shows a section through the straight part of a scissors tree on a somewhat larger scale, and in Figs. 4 and 5 the formation of the tapered part is shown by making a rib. Each of the scissor trees α and b expediently consists of an independent tube, in the straight part of which a wooden insert c is inserted from the rear in a known manner for reinforcement, before the end piece e carrying the eye d was inserted. This end piece is connected to the pipe by a rivet f. The individual scissor boom consists of a cylindrical tube in which an inwardly projecting rib g is formed at the ends of the wall, which increases in height towards the end. The ends of the scissors consist of seamless tube, but are significantly reinforced and tapered with a closed circular cross-section.
