Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung betrifft eine Form, mittelst welcher Prismenglasscheiben u. dergl. angefertigt werden können.The present invention relates to a mold by means of which prismatic glass panes and the like. can be made.

Auf der Zeichnung istOn the drawing is

Fig. ι eine perspectivische Ansicht einer Form mit theilweisem Schnitt,Fig. Ι a perspective view of a Shape with partial cut,

Fig. 2 ein Grundrifs derselben Form.Fig. 2 shows a plan of the same shape.

Fig. 3 ist ein Querschnitt durch die Form, bei welcher sich sämmtliche Theile in ihrer richtigen Lage befinden.Fig. 3 is a cross-section through the mold with all the parts in its right location.

Fig. 4 stellt eine perspectivische Ansicht des Bodens der Form dar, undFig. 4 is a perspective view of the bottom of the mold, and

Fig. 5 stellt perspectivisch eine Prismenglasscheibe dar, die mit der Form hergestellt wurde.Fig. 5 shows a prismatic glass pane in perspective that was made with the mold.

Die FormJi ist mit einem herausnehmbaren Boden oder Formstück B versehen, welches in Berührung mit dem zu formenden Gegenstand tritt. Dieses Formstück B ist mit einer Anzahl Rippen oder Prismen B1 versehen und kann in der Form bewegt werden. Zweckmäfsig bringt man an dem Boden B irgend eine Feststellvorrichtung, wie z. B. die Schraube -B,2, an, wodurch der Boden während des Gebrauchs der Form in jeder gewünschten Stellung festgehalten werden kann. Wie aus der Zeichnung zu ersehen, ruht das Formstück B auf der vorstehenden Leiste B3 und wird von der Leiste oder Fläche J34, die die glatte Fläche B5 an der Prismenscheibe bildet, umfafst.The mold Ji is provided with a removable base or molding B which comes into contact with the object to be molded. This shaped piece B is provided with a number of ribs or prisms B 1 and can be moved in the mold. Expediently, one brings some locking device to the floor B , such as, for. B. the screw -B, 2 , whereby the bottom can be held in any desired position during use of the mold. As can be seen from the drawing, the shaped piece B rests on the protruding bar B 3 and is surrounded by the bar or surface J3 4 , which forms the smooth surface B 5 on the prismatic lens.

Bei Aenderung der Stellung des Bodens B können die gegenseitigen Lagen der Flächen J35 zu den Prismen geändert werden, oder es kann, mit anderen Worten, die Winkelstellung der Prismen in Bezug auf die Kanten der Prismenplatte nach Belieben geändert werden. In Fig. 3 wird die Form mit der darin liegenden Prismenglasscheibe C dargestellt, wobei diese Scheibe sich zwischen dem Prefskolben C1 und dem Formstück B befindet.When changing the position of the bottom B , the mutual positions of the surfaces J3 5 to the prisms can be changed, or, in other words, the angular position of the prisms in relation to the edges of the prism plate can be changed as desired. In Fig. 3 the shape is shown with the prismatic glass pane C lying therein, this pane being located between the piston C 1 and the shaped piece B.

In den Zeichnungen ist eine besondere Ausführungsform der Vorrichtung zum besseren Verständnifs ihrer Anwendung dargestellt, es ist jedoch augenscheinlich, dafs die Form, Construction und die Anordnung der verschiedenen Theile sehr geändert werden kann.In the drawings, a particular embodiment of the device is for the better Understanding of their application, but it is evident that the form Construction and the arrangement of the various parts can be varied greatly.

Man hat nur den Versuch gemacht, die Vorrichtung schematisch und in einer der einfachsten Ausführungsformen darzustellen, und deshalb beschränkt sich auch der Erfinder nicht auf die gezeigte Construction.An attempt has only been made, the device schematically and in one of the simplest Illustrate embodiments, and therefore the inventor is not limited to the construction shown.

Claims (1)

Patent-Anspruch :Patent claim: Preisform zur Herstellung von Glasplatten mit kreisförmig begrenztem Prismenmuster, dadurch gekennzeichnet, dafs der das Prismenmuster enthaltende runde Formboden (B) in der Form (A) gedreht werden kann, um bei Prismenplatten mit eckigem oder unrundem Umfange die Prismen in jedem beliebigen Winkel zu den Seiten der Platte mit einer einzigen Form herstellen zu können.Price form for the production of glass plates with a circularly delimited prism pattern, characterized in that the round bottom (B) containing the prism pattern can be rotated in the shape (A) in order to place the prisms at any angle to the sides in the case of prism plates with angular or non-round circumference to be able to manufacture the plate with a single mold.
