PATENTSCHRIFTPATENT LETTERING
KLASSE 37: Hochbauwesen.CLASS 37: Building construction.
Patentirt im Deutschen Reiche vom 9. Juli 1881 ab.Patented in the German Empire on July 9, 1881.
Die in beiliegender Zeichnung dargestellte Vorrichtung besteht aus den beiden Klammern a und b mit den Oesen d und der iri diesen verschiebbaren Querstange c; die ersteren sind durch die Schrauben s bezw. J1 vermittelst Flügelmuttern verstellbar, so dafs die um 0 drehbaren Backen f in verschiedener Weite aus einander gestellt werden können. Die Vorrichtung hat den Zweck, an Leitern oder Baugerüsten eine für schwere Belastung sichere Unterlage herzustellen; sie wird an einer Leiter, bei welcher eine Sprosse besonders gegen Durchbrechen geschützt werden soll, in der Weise angebracht, dafs jede der,Klammern α und b vermittelst der Schrauben s und S1 fest um einen Leiterbaum gespannt werden kann, und zwar so, dafs die Querstange c in gleiche Höhe mit der zu sichernden Sprosse zu liegen kommt. Die Vorrichtung ist so eingerichtet, dafs sie an der Leiter mit Leichtigkeit verschoben und auch an jeder Leiter, mag sie eng oder weit sein, dicke oder dünne Bäume haben, angebracht werden kann. Wird die Stange c herausgenommen, so können die Klammern einzeln bei jedem Baugerüste Anwendung finden, indem dieselben, an den stehenden Gerüstbäumen befestigt, eine für die Querhölzer solide und leicht verstellbare Unterlage bilden.The device shown in the accompanying drawing consists of the two brackets a and b with the eyelets d and the iri these displaceable crossbar c; the former are through the screws s respectively. J 1 adjustable by means of wing nuts, so that the jaws f , which can be rotated by 0 , can be set apart from one another in different widths. The purpose of the device is to create a base that is safe for heavy loads on ladders or scaffolding; it is attached to a ladder in which a rung is to be specially protected against breaking through, in such a way that each of the brackets α and b can be clamped tightly around a ladder tree by means of the screws s and S 1, in such a way that the crossbar c comes to rest at the same height as the rung to be secured. The device is arranged so that it can be moved with ease on the ladder and also attached to any ladder, narrow or wide, with thick or thin trees. If the rod c is removed, the clamps can be used individually for each scaffolding, in that the same, attached to the standing scaffolding trees, form a solid and easily adjustable base for the crossbars.
