Es sind bereits Maschinen zum Gießen und Bearbeiten gebogener Stereotypplatten bekannt, bei welchen die Platten in einer wagerechten, aus einem konkaven Mantel und einem zylindrischen Kern bestehenden Gießform gegossen und durch Drehen des Kernes aus der Gießform herausbewegt werden, worauf die Bearbeitung der Platte erfolgt, indem sie auf einer wagerechten Bahn entlang geschoben wird. Es sind auch schon Vorrichtungen zum Fertigmachen solcher Platten vorgeschlagen worden, bei welchen die Platte durch ihre eigene Schwere an einer geneigt liegenden Bahn entlang gleitet und hierbei der Reihe nach zu den Messern zumMachines for casting and processing bent stereotype plates are already known, in which the plates in a horizontal, from a concave jacket and a cylindrical Core existing casting mold and moved out of the casting mold by rotating the core, whereupon the processing the plate is done by sliding it along a horizontal path. There are Devices for making such panels have also been proposed, in which the plate slides due to its own gravity along an inclined path and here one after the other to the knives for

*5 Bearbeiten der Seitenkanten, der Innenfläche, der gebogenen Enden und dann zu dem Kühler gelangt. Das Gießen der Platte erfolgt hierbei in einer senkrecht stehenden Gießform, die aus einem konkaven Mantel und einem halbzylindrischen Kern besteht, und die Platte wird durch Schwenken des Kernes um eine Querachse um etwas mehr als einen Viertelkreis auf die geneigte Bahn gebracht.
Bei der ersterwähnten Anordnung erfordert die ganze Bewegung der Platte an der wagerechten Bahn entlang einen Aufwand von Kraft durch den die Vorrichtung antreibenden Motor, und bei der letzterwähnten bedingt die ganze Bewegung des Kernes und der Platte aus der geöffneten Form bis zum Umkippen des Kernes 35* 5 Machining the side edges, the inner surface, the bent ends and then getting to the radiator. The casting of the plate takes place in a vertical casting mold, which consists of a concave jacket and a semi-cylindrical core, and the plate is brought onto the inclined path by pivoting the core about a transverse axis by a little more than a quarter of a circle.
In the former arrangement, the entire movement of the plate along the horizontal path requires an application of force by the motor driving the device, and in the latter arrangement requires the entire movement of the core and the plate from the open mold until the core 35 overturns

einen gewissen Zeitaufwand und eine Kraftanstrengung des Arbeiters.a certain amount of time and effort on the part of the worker.

Gemäß der vorliegenden Erfindung sollen diese Übelstände dadurch vermieden werden, daß auch die Form so geneigt angeordnet ist, daß die Platte, sobald sie von dem Kern frei wird, selbsttätig durch ihr Eigengewicht aus der Gießform heraus- und auf der geneigten Bahn entlanggleitet, wobei die Angüsse, welche infolge der geneigten Lage der Bahn in einer tieferen Ebene von der Platte abgeschnitten werden, als der Metalltopf liegt, aus welchem die Gießform gefüllt wird, in dieser Höhe aufgenommen und selbsttätig in den Metalltopf gebracht werden.According to the present invention, these inconveniences are to be avoided in that also the form is inclined so that the plate, as soon as it is free from the core, automatically slides out of the mold due to its own weight and along the inclined track, the sprues, which are cut from the plate as a result of the inclined position of the web in a lower plane, than the metal pot from which the mold is filled is added at this height and automatically placed in the metal pot.

In der Zeichnung sind A der Maschinenrahmen, B eine Plattform für den Arbeiter, und b Stufen, die auf die Plattform führen. D ist die Fertigmach- und E die Kühlvorrichtung. Die Gießform C ebenso wie die Fertigmachvorrichtung D liegen so zur Wagerechten geneigt, daß die Stereotypplatte, die in bekannter Weise in der Gießform gegossen wird, durch ihre SchwereIn the drawing, A is the machine frame, B is a platform for the worker, and b is steps leading to the platform. D is the finishing device and E is the cooling device. The casting mold C as well as the finishing device D are inclined to the horizontal so that the stereotype plate, which is cast in the casting mold in a known manner, by its gravity

is continued to the finishing device and through this into the cooling device slides in.

The casting mold consists of the cylindrical core 13 and the jacket 32. The former is rotatably arranged in a known manner. On its outside it is provided with indentations 29 "to make lugs on the sprue of the plate and it has two rows of teeth 30 which create a rack on the concave side of each plate. Once a plate is in the mold in a known manner is poured, is der'Mantel-32, which is below the cylindrical core and this comprises in half, removed from the working position to bottom. It slides with its rollers 41 on rails 42 on the machine frame its movement is effected by the handle ^H3. . will now be made by coupling of the insert core with the main drive of the machine rotation thereof about i8o °, so that the cast plate, which adheres to the core comes to lie above the core. In this position, it is raised by plate lifters 73 rotatably are arranged on bearings 62, 63. When the shell 32 is moved into the working position for casting the next plate through the shell, they are rotated so that they lift the previously cast plate from the core and form an inclined slide which is parallel to the axis of the mold and on which the plate slides freely downwards.
In order to retard the sliding movement of the plate, a braking device can be provided which is in engagement with the racks cast onto the plate.

The plate is moved in this way towards the scraper housing D , where it is clamped, rotated and scraped. At the same time, the sprue of the plate is cut off with the aid of a saw 90. The cut-off parts fall through a channel 91 onto an inclined platform 92. Here they rotate due to their weight so that their axis comes to lie parallel to the direction of an endless conveyor device 93. The latter is moved by a motor K ² and has a chain with a series of projections 94 which engage the sprues and place them on the. Create path 95 along on a platform 96 above the ladle F. From there they fall through a channel 97 into the pouring pot. Plates to be melted can also be placed manually or mechanically on the transport device and transported into the casting pot in the same way.

Godfather τ-An saying:

Device for casting, finishing and cooling of curved stereotype plates, in which the gravity of the plate along an inclined path through the Machining after the cooling device slides, characterized in that also the mold in the same inclined direction, at the highest point of the Web lies so that the plate by its gravity from 'the mold out on the inclined path arrives, with the sprues of the panels cut off in a lower position than that of the melting pot is automatically raised and conveyed into the melting pot.
