Description

Glocken- und Schirmhalter. Ilie bekanntgewordenen Versuche, Schraubenfedernringe zu Glockenhaltern zu benutzen, führten deshalb nicht zur Einführung des Artikels in die Praxis, weil die Ringe mangelhaft geschlossen waren. Es wurde entweder die zur Herstellung des Ringes bestimmte Feder konisch gewickelt und das dünne Ende in das weitere eingeschraubt, oder man lötete die Enden zusammen, auch wurde über die Enden eine Metallhülse geschoben. Bei diesen Methoden war die Gefahr vorhanden, daß sich der Ring beim Aufspannen über den Schirrnrand löste.Bell and umbrella holder. Ilie known attempts at coil spring washers to use it for bell holders, therefore, did not lead to the introduction of the article into practice because the rings were not closed properly. It was either the for the production of the ring, the spring is conically wound and the thin end screwed into the other, or you soldered the ends together, also was over the ends pushed a metal sleeve. With these methods there was a danger that the ring came loose when it was stretched over the edge of the frame.

Diesem Übelstande hilft die vorliegende Erfindung dadurch ab, daß in die Enden der zum Ringe zu verwendenden Schra.Übenfeder eine aus gleich starkem Draht gewickelte Feder von geringerem Durchmesser eingeschraubt wird. Die Windungen der dünnen Feder schrauben sich in die Gänge dfr umschließenden-Feder ein und der Ring ist durch Dehnung nicht auseinander zu reißen.The present invention remedies this drawback in that into the ends of the screw to be used for the ring Wire-wound spring of smaller diameter is screwed in. The turns the thin spring screw themselves into the gears dfr enclosing spring and the The ring cannot be torn apart by stretching.
