Tragbahre.
Patentiert im Deutschen Reiche vom 12. Oktober 1902 ab. Stretcher.
Patented in the German Empire on October 12, 1902.
Den Gegenstand der Erfindung bildet eine besondere Konstruktion für Holme von Tragbahren, bei welcher als Erfindungsidee die Tatsache zugrunde liegt, daß Stahl- oder Eisenblech, wenn es auf die hohe Kante gestellt wird und nicht ausweichen kann, imstande ist, ganz bedeutende Lasten zu tragen.The subject of the invention is a special construction for struts of stretchers, in which the idea of the invention is based on the fact that steel or iron sheet, if it is put on the high edge and cannot avoid it, is able to carry very significant burdens.
Beiliegende Zeichnung stellt den Querschnitt eines Tragholms dar. Ih eine leichte ίο Stahlplatte M ist eine sogen. Sicke χ gepreßt und um diese Stahlplatte eine Holzumkleidung ρ gelegt. Diese Holzumkleidung, welche durch die eingepreßte Sicke mitgehalten wird, dient dazu, ein Ausweichen des Stahlblechs zu verhindern; den eigentlichen tragenden Teil bildet das Stahlblech M. Der beste Beweis für die Eigenartigkeit der Erfindung liegt darin, daß die Holme nur senkrecht zum Tragen benutzt werden können; auf die flache Seite gelegt, verbiegen sie sich schon bei geringer Belastung.The accompanying drawing shows the cross section of a support beam. Ih a light ίο steel plate M is a so-called. Pressed the bead χ and put a wooden cladding ρ around this steel plate. This wooden cladding, which is held in place by the pressed-in bead, serves to prevent the steel sheet from dodging; the actual load-bearing part is made of sheet steel M. The best proof of the peculiarity of the invention lies in the fact that the spars can only be used vertically for carrying; When placed on the flat side, they bend even when the load is low.
