Description

Bolzensicherung für die Befestigung von Schlägern an Schlägermühlen Zusatz zum Patent 655 957 Die Erfindung betrifft eü-ie Bolzensicherung für die Befestigung von Schlägern an Schlägermühlen zeit S-förmigem Stift nach Patent 655 957 und besteht darin, daß zur Sicherung der Bolzenverbindung zwischen Schlägerkopf und Schlägerschaft das eine Ende des Stiftes in einer radialen Bohrung des Bolzens und das andere Ende in einer offenen Nut des Schlägerkopfes liegt.Bolt securing device for attaching bats to beater mills Addition to patent 655 957 The invention relates to eü-ie bolt securing device for attaching bats to beater mills time S-shaped pin according to patent 655 957 and consists in the fact that to secure the bolt connection between the club head and the club shaft one end of the pin lies in a radial bore in the bolt and the other end in an open groove in the club head.

Die Befestigung des auswechselbaren Schlägerkopfes am Schlägerschaft soll leicht lösbar sein und keinem Verschleiß unterliegen. Dazu eignet sich die Befestigung von Schlägern bei Schlägermühlen mit S-förmigem Stift nach Patent 655 957 besonders gut, weil sie keine bearbeiteten Paßfiächen benötigt. Da jedoch bei der Befestigung des Schlägerkopfes der Bolzen nicht vorstehen darf, wird erfindungsgemäß das Schlußende des Stiftes in eine Ausnehmung an dem Schlägerkopf verlegt. Durch diese Anordnung wird eine gesicherte, aber lockere Verbindung geschaffen, so daß unbearbeitete Schmiede- oder Gußstücke benutzt werden können. Dies ist bei Schlägerköpfen besonders wichtig, weil sie oft wegen Verschleißfestigkeit in so hartem Zustande hergestellt werden, daß eine Bearbeitung sehr erschwert wird.The attachment of the exchangeable club head to the club shaft should be easily detachable and not subject to wear and tear. The Fastening of beater on beater mills with S-shaped pin according to patent 655 957 is particularly good because it does not require any machined fitting surfaces. However, since the fastening of the club head, the bolt must not protrude, is according to the invention relocated the tail end of the pin in a recess on the club head. By this arrangement creates a secure but loose connection so that unprocessed forgings or castings can be used. This is with club heads especially important because they are often in such a hard condition because of their wear resistance be produced that processing is very difficult.

In der Abbildung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt. Der Schlägerkopf r ist durch den Bolzen ä drehbar mit dem Schlägerschaft 3 verbunden. Der Bolzen hat eine radiale Bohrung q. und eine Längsnut 5, in welche vor dem Einsetzen des Bolzens der hakenförmige Stift 6 eingelegt wird. Nach dem Einsetzen des Bolzens wird mit einigen Hammerschlägen das herausstehende Ende des Stiftes umgeschlagen; so daß es gegen Verschleiß geschützt in der Nut 7 des Schlägerkopfes liegt.In the figure, the subject of the invention is in one embodiment shown. The club head r is rotatable with the club shaft through the bolt ä 3 connected. The bolt has a radial bore q. and a longitudinal groove 5 into which before inserting the bolt, the hook-shaped pin 6 is inserted. After this Insertion of the bolt will remove the protruding end of the with a few blows of the hammer Pen turned over; so that it is protected against wear in the groove 7 of the club head lies.

Zur Sicherung gegen Verschieben in der anderen Richtung kann die gleiche Anordnung getroffen werden, oder der Bolzen kann mit einem Versenkkopf 8, wie dargestellt, versehen sein.The same can be used to secure against shifting in the other direction Arrangement can be made, or the bolt can be fitted with a countersunk head 8, as shown, be provided.
