PATENTAMT.PATENT OFFICE.
Die gewöhnlichen Stiftführungen von Formkästen u. dgl. sind einem überaus großen Verschleiß unterworfen, was ein Verschieben der aufeinandergelegten Formkästen beim Formen und damit ungenaue (übersetzte) Gußstücke, welche als Fehlguß einen großen Schaden für jede Gießerei bedeuten, zur Folge hat.The usual pin guides of molding boxes and the like are extremely wear-and-tear subject to displacement of the flasks placed one on top of the other during molding and thus imprecise (translated) castings, which as a failed casting mean great damage to any foundry.
Diesen Übelstand soll diese Erfindung verhindern. Sie ist in der Zeichnung dargestellt. ίο Fig. ι zeigt zwei Formkastenteile zusammengesetzt. This invention is intended to prevent this inconvenience. It is shown in the drawing. ίο Fig. ι shows two molding box parts assembled.
Fig. 2 zeigt im Schnitt und Grundriß ein Formkastenaugenpaar mit eingesetzter und festgeklemmter Feder.Fig. 2 shows in section and plan a molding box eye pair with inserted and clamped spring.
1S Fig- 3 zeigt die Feder im ruhenden Zustande. 1 S Fig- 3 shows the spring in the resting state.
In einer Nut eines Formkastenauges b liegtIn a groove of a molding box eye b lies
eine Feder f, die durch den Führungsstift c oder dessen kegelförmigen Kopf in die Nut zurückgedrückt wird. Durch die Federkraft wird ein stets inniges Anpressen der Feder an den Schaft des Führungsstiftes stattfinden. Der Lappen h der Feder verhindert ein Hineindringen von hemmenden Gegenständen. Die Befestigung der Feder an dem Auge geschieht durch ein Schräubchen e und Lappen a. Durch ein Loch g können etwa eingedrungene Fremdkörper leicht entfernt werden.a spring f, which is pressed back into the groove by the guide pin c or its conical head. The spring force will always press the spring closely against the shaft of the guide pin. The tab h of the spring prevents obstructing objects from entering. The spring is attached to the eye by means of a screw e and a flap a. Any foreign bodies which may have penetrated can be easily removed through a hole g.
