KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Vorliegende Erfindung bezweckt, durch eine besondere Anordnung im Formkasten das Herausnehmen des Steines aus der Form zu erleichtern.The present invention aims, through a special arrangement in the molding box To facilitate removal of the stone from the mold. Zur Erreichung dieses Zweckes sind die Seitenwände der Form in bekannter Weise umklappbar am Formboden angeordnet, wobei zum Schließen der Formwände die bekannten Verschlußvorrichtungen, Hebel, Schraube,To achieve this, the side walls of the mold are in a known manner Foldable arranged on the bottom of the mold, the known ones for closing the mold walls Locking devices, levers, screws, ίο Keil ο. dgl., verwendet werden. In dem Boden der Form befindet sich nun nach vorliegender Erfindung an beiden Enden je eine Aussparung, in welche je ein an gegenüberliegenden , umklappbaren Formwänden angebrachtes Ansatzstück hineinpaßt. Bei geschlossener Form liegen diese Ansatzstücke vollständig in den Aussparungen des Bodens. Wird aber die Form geöffnet, so treten sie beim Umklappen der Seitenwände, an der sie befestigt sind, aus der Aussparung nach oben heraus, und heben damit den Stein so hoch, daß er bequem aus der Form herausgenommen werden kann.ίο wedge ο. Like., can be used. By doing According to the present invention, the bottom of the mold is now one at each end Recess, in each of which one attached to opposing, foldable mold walls End piece fits into it. When the form is closed, these extension pieces lie completely in the recesses in the floor. But if the mold is opened, they occur when the side walls are folded down, on which they are are attached, out of the recess upwards, and thus lift the stone so high that that it can be easily removed from the mold. Fig. ι zeigt einen Schnitt durch den Formkasten, Fig. Ι shows a section through the molding box, Fig. 2 eine Oberansicht.Fig. 2 is a top view. Der Formkasten wird gebildet durch die Wände b, b, c, c und den Boden a, an welchem die Wände drehbar fest sind. Diese Befestigung sowie die Verbindung der Wände miteinander bei geschlossener Form ist der besseren Übersicht halber nicht gezeichnet.The molding box is formed by the walls b, b, c, c and the bottom a, on which the walls are rotatably fixed. This fastening and the connection of the walls to one another when the form is closed is not shown for the sake of clarity. An den Querwänden b befinden sich die Ansätze d, welche sich bei geschlossener Form in die Bodenaussparungen 0 legen. Wenn der Formling fertiggestellt ist, werden die Wände b, welche die Ansätze d tragen , heruntergeklappt. Dadurch wird der Formling (Fig. 1) angehoben, so daß er an seinem oberen Ende bequem erfaßt werden kann. Zum Herausnehmen bedarf es also keiner Lagen veränderung der Form.On the transverse walls b are the approaches d, which are placed in the floor recesses 0 when the mold is closed. If the molding is completed, the walls are b carrying the approaches d, folded down. As a result, the molding (Fig. 1) is raised so that it can be comfortably grasped at its upper end. So there is no need to change the position of the shape to remove it.
