Description
Schmiedeeiserner Kappschuh aus Flacheisen Schmiedeeiserne Kappschuhe aus Flacheisen, deren eines Ende hakenförmig gegen denKappenkopf greift und in dessen auf dem Stempelkopf aufliegenden Teil Löcher vorgesehen sind, durch die Drahtstifte oder sonstige Formstifte vor dem Stempel eingetrieben werden, sind bekannt.Wrought iron shoe made of flat iron Wrought iron shoe made of flat iron, one end of which engages in the shape of a hook against the cap head and in its Holes are provided on the part of the punch head resting through the wire pins or other shaped pins are driven in front of the punch are known.
Nach der Erfindung ist bei derartigen Kappschuhen das freie Ende zur Erzielung einer Nachgiebigkeit in Kappenlängsrichtung erst in einem etwa der Länge der Drahtstifte entsprechenden Abstand von der der Strecke zugekehrten Fläche des Stempels etwa rechtwinklig nach der der Kappe entgegengesetzten Richtung umgebogen, um dem Stempel in der Endstellung als Widerlager zu dienen.According to the invention, the free end of such clipping shoes is to Achieving flexibility in the longitudinal direction of the cap only in about the length of the wire pins corresponding to the distance from the surface of the line facing the line Stamp bent approximately at right angles in the direction opposite to the cap, to serve as an abutment for the stamp in the end position.
Tritt bei Verwendung dieser Kappschuhe ein seitlicher Druck auf, der den Stempel in die Bahn bzw. in die Strecke hineinpressen will, so ziehen sich die Drahtstifte allmählich aus dem Stempel heraus, wobei dieselben rechtwinklig umgebogen werden. Versuche haben bewiesen, daß man in der Lage ist, praktisch jeden seitlich auftretenden Druck aufzufangen und langsam sich auswirken zu lassen. Die Grenze der Nachgiebigkeit kann hierbei reguliert werden durch entsprechende Länge des Kappschuhs selbst und der Drahtstifte. Die zur Verwendung kommenden Drahtstifte sind etwa 15 bis 2o cm lang. In der Zeichnung ist der Gegenstand der Erfindung dargestellt. Nach Abb. z und 2 hat sich der Stempel noch nicht durch den Gebirgsdruck zum Kappschuh verschoben. Nach Abb. 3 und q. haben sich die Drahtstifte durch die Verschiebung des Stempels zum Kappschuh zu einem Teil ihrer Länge aus dem Stempel herausgezogen. Nach der Zeichnung sind der Kappschuh mit =, die Drahtstifte mit 2, die Kappe mit 3 und der Stempel mit q. bezeichnet.If there is pressure on the side when using these capping shoes, the wants to press the punch into the web or into the track, the pull Wire pins gradually out of the punch, the same bent over at right angles will. Tests have shown that one is able to sideways practically everyone to absorb the pressure and slowly let it take effect. The border the flexibility can be regulated by the appropriate length of the shoe itself and the wire pins. The wire nails to be used are around 15 up to 20 cm long. In the drawing, the subject matter of the invention is shown. To Fig. Z and 2, the stamp has not yet become a cap shoe due to the pressure of the mountains postponed. According to Fig. 3 and q. got the wire pins through the shift of the punch to the capping shoe pulled out of the punch to a part of its length. According to the drawing, the cap with =, the wire pins with 2, the cap with 3 and the stamp with q. designated.
