 mittlung der Rollen 3r und der Führungsschlitze   8   der   Unterkasten     selbsttätig in   die wagerechte Lage niederklappt. In dieser Stellung verbleibt der   Unterkasten   bis nach dem Entfernen der gegossenen Stereotypplatte und der Vorbereitung der Matrize. Die   Lagerzapfen < ?'' fü)   den Unterkasten sind so angeordnet, dass der Kasten ausbalanziert ist und bei seiner   Längsverschiebung   selbsttätig in die senkrechte oder wagerechte Lage übergeführt wird. 



   Um den Unterkasten mit dem Giessformmantel während des Giessens sicher   zusammen   zu halten, ist derselbe in der Nähe seiner Lagerzapfen mit Stiften   3g (Fig. 2, 4- und   5) versehen, über welche Haken 4g greifen können, die auf einer exzentrisch gelagerten, hin- und herschwingbaren Welle 4 lose drehbar sitzen. Diese Welle 4 ist mit exzentrischen Lagerteilen 4a (Fig. 8) ausgerüstet, mit deren Hilfe sie in Lagermuffen 2a (Fig.   I   und 3) an der hinteren   Giessformmantel-   fläche ruhen. 



   Neben den Haken sind auf der Welle Muffen 4b (Fig.   l   und 3) befestigt, welche   Stifte 4c   (Fig. 4 und 5) tragen und deren eine gleichzeitig die Kurbelnabe bildet. Diese Stifte greifen in bogenförmige Schlitze 4d an der   Stirnfläche   der benachbarten Hakennabe ein. Auf diese Weise kann also die Welle 4 durch die Kurbel   4x im Rinne   des Uhrzeigers (mit Bezug auf Fig. 4) teilweise gedreht werden, ohne die   Haken 49   mitzunehmen.

   Sobald aber die Stifte 4c der Naben 4b das hintere Ende des Schlitzes 4d erreichen und die Kurbel in die aus Fig. 5 ersichtliche Lage

   Durch die exzentrische Lagerung der Welle 4 wird ferner bewirkt, dass nach dem   Schliessen   der Haken durch die weitere   Abwärtsbewegung   der Kurbel   4x   die Haken den   Unterkasten   fest

 EMI2.1
 Averaging the rollers 3r and the guide slots 8, the lower box automatically folds down into the horizontal position. The lower box remains in this position until after the cast stereotype plate has been removed and the matrix has been prepared. The bearing journals <? '' For the lower box are arranged in such a way that the box is balanced and automatically moved into the vertical or horizontal position when it is moved lengthways.



   In order to hold the lower box with the casting mold shell together securely during casting, the same is provided with pins 3g (Fig. 2, 4- and 5) in the vicinity of its bearing pins, via which hooks 4g, which are mounted on an eccentrically mounted, can grip - And swingable shaft 4 sit loosely rotatable. This shaft 4 is equipped with eccentric bearing parts 4a (FIG. 8), with the aid of which they rest in bearing sleeves 2a (FIGS. 1 and 3) on the rear surface of the casting mold.



   In addition to the hooks, sleeves 4b (Fig. 1 and 3) are attached to the shaft, which pins 4c (Fig. 4 and 5) carry and one of which forms the crank hub at the same time. These pins engage in arcuate slots 4d on the face of the adjacent hook hub. In this way, the shaft 4 can thus be partially rotated by the crank 4x in the clockwise groove (with reference to FIG. 4) without taking the hooks 49 with it.

   But as soon as the pins 4c of the hubs 4b reach the rear end of the slot 4d and the crank into the position shown in FIG
 EMI2.2
   If the pins 3g are brought into engagement, the disks are in such a position that they do not prevent the hooks 4 ″ from firmly gripping the pins.



   The eccentric mounting of the shaft 4 also has the effect that, after the hooks have been closed, the further downward movement of the crank 4x causes the hooks to fix the lower box

 to reach. When the crank is swinging backwards, the hooks 4R fall over the pins 3g by their own weight. The balancing of the lower case means that practically no effort is required to move it from the horizontal to the vertical position.
