Description

KAISERLICHESIMPERIAL

PATENTAMT,PATENT OFFICE,

Bisher sicherte man Schrauben in nicht durchgehenden Löchern in der Weise, daß man die Schraube am unteren Ende ausbohrte. In diese Bohrung ließ man einen sich verjüngenden Körper einzwängen, der vorher in das Schraubenloch eingebracht war. Durch das Einzwängen sollte das untere Schraubenende auseinandergetrieben und dadurch eine Sicherung der Schraube ίο erzeugt werden, doch war es bisher nicht möglich, eine Schraube in hartem Stoff genügend zu sichern, da dieser der Ausdehnung der Schraube zu großen Widerstand entgegensetzte. Dieser Übelstand wird durch die Erfindung beseitigt, indem man zwischen Schraubenlochwand und Schraube selbst eine Gewindebuchse einschaltet, die nicht bis auf den Grund des Schraubenloches hinabreicht und hierdurch einen Hohlraum schafft, in dem sich das Schraubenende genügend ausbreiten kann.So far, screws have been secured in non-through holes in such a way that the screw at the bottom was drilled out. One was let into this hole constrain the tapered body that was previously inserted into the screw hole was. The cramping should force the lower end of the screw apart, thereby securing the screw ίο be generated, but it was not previously possible to find a screw in hard material enough to secure, as this opposed the expansion of the screw too great resistance. This drawback is eliminated by the invention by placing one between the screw hole wall and the screw itself Turns on the threaded bushing that does not reach down to the bottom of the screw hole and thereby creates a cavity in which the screw end can spread out sufficiently can.

Der Erfindungsgegenstand ist auf der Zeichnung veranschaulicht, und zwar zeigtThe subject of the invention is illustrated in the drawing, namely shows

Fig. 3 und'4 zeigen dieselben Anordnungen, jedoch mit einer Abänderung an der Gewindebuchse.
Fig. 2 during the same.
Figures 3 and 4 show the same arrangements, but with a modification to the threaded bushing.

Fig. 5 und 6 veranschaulichen die gleichartige Sicherung von Rohrenden in Muffen. Der Schraubenbolzen α ist zwecks Sicherung auf der am Ende des Gewindes befindlichen Stirnseite in bekannter Weise ausgebohrt. Zwischen Schraubenbolzen und Schraubenloch ist eine Gewindebuchse oder ein Futter b eingeschaltet, das nicht ganz bis auf den Grund der Schraubenbohrung reicht. Der in die letztere eingebrachte Körper c kann dadurch das untere Ende des Schraubenbolzens α beim Einschrauben auseinanderzwängen und so die Schraube in ihrer Lage sichern. Die Buchse b besteht entweder aus einer rings geschlossenen Hülse, oder sie ist durch schraubenförmiges Aufwinden von Draht oder passendem Formmetall hergestellt (Fig. 3 und 4).5 and 6 illustrate the similar securing of pipe ends in sleeves. The screw bolt α is drilled out in a known manner for the purpose of securing on the end face located at the end of the thread. A threaded bushing or a chuck b is inserted between the screw bolt and the screw hole, which does not extend all the way to the bottom of the screw hole. The body c introduced into the latter can thereby force the lower end of the screw bolt α apart as it is screwed in and thus secure the screw in its position. The socket b consists either of a sleeve closed around the ring, or it is produced by winding wire or suitable shaped metal in a helical manner (FIGS. 3 and 4).

Bei der Sicherung von Rohrenden in einer Muffe d wird in die letztere von beiden Seiten ein Gewindemantel e eingeschraubt. Beide Mäntel lassen in der Mitte der Muffe einen Raum frei, in den die Enden der Rohre f durch eine Muffe g gedrängt werden. Die Muffe g ist zu diesem Zweck in bekannter Weise beiderseitig kegelförmig oder ähnlich gestaltet.When securing pipe ends in a socket d , a threaded jacket e is screwed into the latter from both sides. Both jackets leave a space in the middle of the socket, into which the ends of the pipes f are forced by a socket g. For this purpose, the sleeve g is designed to be conical or similar on both sides in a known manner.
