   PATENTANSPRüCHE : 
1. Vorrichtung zum Giessen gebogener Stereotypplatten, bei der, nachdem der Formmantel vom Kern entfernt und dieser um 1800 gedreht wurde, der Kern selbsttätig vom Mantel gelöst wird, dadurch   gekennzeichnet,   dass der Kern (c) während des Giessens   dur... a einen   Handhebel   (120)   gesperrt gehalten wird, durch dessen Betätigung der Kern nach dem Giessen freigegeben und dann die Antriebskupplung   (M,   117) zur Drehung des Kernes geschlossen wird, die während des nächsten   Giessvorgangs durch Einwirkung einer Feder (12) auf den Hebel (120) selbsttätig wieder ge- öffnet wird.

 this indicates to the caster that the mold can be opened and the cooled stereotype plate can be removed.



   PATENT CLAIMS:
1. Device for casting bent stereotype plates, in which, after the mold shell has been removed from the core and this has been rotated by 1800, the core is automatically detached from the shell, characterized in that the core (c) dur ... a one during casting Hand lever (120) is kept locked, the actuation of which releases the core after casting and then closes the drive coupling (M, 117) for rotating the core, which during the next casting process is activated by the action of a spring (12) on the lever (120 ) opens again automatically.

Claims

Bare carrier (135) of this lever is rotated until the lever is brought out of engagement with the ratchet wheel by a stop (148) which can be adjusted according to the time required to cool a stereotype plate, whereupon the one-sided loaded, provided with a nose (136) Carrier sinks back into its rest position and gives an audible signal by striking this nose against a fixed pin (137).

3. Device according to claim 2, characterized in that the adjustable stop (148) which determines the duration of the lever engagement is designed as a lever which can be swung around the axis of the ratchet wheel and can be determined in any position.
