Description

Um Schrauben, die langer im Gebrauch durch Witterungseinflüsse usw. eingerostet sind, zu lösen, ist es meist erforderlich, dieselben abzubrennen, zu zersägen oder abzumeißeln. Dieses Übel will vorstehende Erfindung dadurch beseitigen, daß der Bolzenkopf vom Bolzen lösbar ist. Zu diesem Zweck ist der Bolzenkopf schwalbenschwanzförmig oder mit Nut und Feder oder mitAbout screws that have rusted longer in use due to weathering, etc. are to be solved, it is usually necessary to burn them off, to saw them or to chisel them off. The present invention aims to eliminate this evil in that the bolt head is detachable from the bolt. To this Purpose is the bolt head dovetail or with tongue and groove or with

ίο beliebiger Profilart über den entsprechend ausgearbeiteten Bolzen geschoben. Dieser Kopf läßt sich durch Hammerschläge trotz angezogener Mutter lösen.ίο any profile type via the corresponding elaborated bolt pushed. This head can be defeated by hammer blows loosen the tightened nut.

Abb. ι der Zeichnung stellt einen sechskantigen Bolzenkopf mit schwalbenschwanzförmiger Aussparung dar.Fig. Ι of the drawing represents a hexagonal bolt head with a dovetail Recess.

Abb. 2 zeigt, daß die schwalbenschwanzförmige Aussparung den Mittelpunkt des Kopfes so weit überschreitet, daß der inFig. 2 shows that the dovetail-shaped recess is the center of the Head so far that the in

Abb. 3 dargestellte Schraubenbolzen seitlich eingeschoben werden kann und in der Schlußstellung genau in der Mitte des Kopfes sitzt. Die Aussparung des Kopfes ist, wie aus Abb. 2 ersichtlich, nach dem Außenrand des Kopfes hin kegelig erweitert, so daß der Kopf durch einen Hammerschlag leicht gelockert und seitlich entfernt werden kann. Nunmehr kann der Bolzen rückwärts aus der Bohrung genommen werden.Fig. 3 screw bolt shown can be inserted laterally and in the Final position sits exactly in the middle of the head. The recess of the head is how can be seen from Fig. 2, widened conically towards the outer edge of the head, so that the The head can be easily loosened with a blow of the hammer and removed to the side. The bolt can now be removed from the bore backwards.

Abb. 4 zeigt dieselbe Einrichtung an Versenkschrauben c. Die Mutter ist hier als Hülsenmutter d ausgebildet und ebenfalls mit dem Schwalbenschwanz b versehen, auf welchen der Kopf aufgeschoben wird.Fig. 4 shows the same device on countersunk screws c. The nut is designed here as a sleeve nut d and also provided with the dovetail b on which the head is pushed.
