Heinrich Bachmann in Magdeburg Paßstift nach Patent 597 585Heinrich Bachmann in Magdeburg dowel pin according to patent 597 585
Zusatz zum Patent 597 585Addition to patent 597 585
Patentiert im Deutschen Reiche vom 23. Juli 1930 ab Das Hauptpatent hat angefangen am 2. April 1930.Patented in the German Empire from July 23, 1930 onwards The main patent started on April 2, 1930.
Der in dem Hauptpatent beschriebene Paßstift kann gemäß vorliegender Erfindung noch verbessert werden. Wenn der konische Paßstift aus Rohr hergestellt wird, so muß das Aufschlitzen; mit einem umlaufenden Werkzeug vorgenommen werden. Man kann dann dieses Werkzeug so einstellen, daß es am schwachen Ende allmählich aus dem Stift herausgeht und auf der Innenseite eine Wandung stehenbleibt, jedoch auf der Außenseite des Stiftes eine Nut erzeugt wird. Es bleibt dann, wie beim Hauptpatent, das untere schwache Ende des Stiftes, das als Führung dient, geschlossen. Es entsteht aber in dem Ende eine -Nut, deren Rand federnd wirkt, ■ wodurch der Festsitz des Stiftes erhöht wird. Der Stift ist also in bezug auf Herstellung und Anwendung verbessert.The dowel pin described in the main patent can according to the present invention still to be improved. If the conical dowel is made from pipe, it must the slitting; can be made with a rotating tool. One can then adjust this tool so that it gradually comes out of the pen at the weak end and one on the inside Wall remains, but a groove is created on the outside of the pin. It then remains, as with the main patent, the lower weak end of the pin, which acts as a guide serves, closed. But there is a groove in the end, the edge of which has a resilient effect, ■ which increases the tight fit of the pen. The pen is thus improved in terms of manufacture and use.
Auf der Zeichnung sind zwei Ausführungsbeispiele des Stiftes gemäß der Erfindung dargestellt.In the drawing are two embodiments of the pen according to the invention shown.
Der Stift nach Fig. 1 besteht aus einem konischen Rohr 1, das mit einem Längsschlitz 2 versehen ist. Am schwachen Ende des Stiftes läuft der Schlitz, der durch eine Fräserscheibe hergestellt ist, in eine allmählich flacher werdende Nut 3 aus. Der Durchmesser des schwachen Endes braucht nicht größer zu sein als der Durchmesser der Lochbohrung, da der Stift an der Stelle, an der sich die Nut befindet, beim Einschlagen nicht nach außen, sondern nach innen federt. Der Stift braucht nicht aus einem Rohr zu bestehen, sondern kann auch aus Vollmaterial (ia) hergestellt werden, das fast seiner ganzen Länge nach durchbohrt ist. Ein Stift dieser Art, der sich im übrigen nicht von dem Stift nach Fig. 1 unterscheidet, zeigt die Fig. 2.The pin according to FIG. 1 consists of a conical tube 1 which is provided with a longitudinal slot 2. At the weak end of the pin, the slot, which is made by a milling disk, ends in a groove 3 that gradually becomes flatter. The diameter of the weak end does not need to be larger than the diameter of the hole, since the pin at the point where the groove is located does not spring outwards when it is hammered in, but inwards. The pin does not have to consist of a tube, but can also be made of solid material ( i a ) that is drilled through almost its entire length. A pen of this type, which does not otherwise differ from the pen according to FIG. 1, is shown in FIG. 2.
