Description

Gegenstand vorliegender Erfindung ist eine Lichtpausmaschine mit rotierendem Glaszylinder, in welchem die elektrischen Lichtquellen, Bogenlampe, so aufgehängt bzw. befestigt sind, daß dieselben zu jeder Zeit, auch wenn die Maschine in Betrieb ist, herausgenommen oder eingesetzt werden können, es ist dieses ein Vorteil, den keine der bis jetzt bekannten Lichtpausmaschinen aufweist. Die Erfindung ist in ίο der Zeichnung beispielsweise dargestellt:The subject of the present invention is a blueprint machine with a rotating glass cylinder, in which the electric light sources, arc lamps, are suspended or attached, that the same at any time, even when the machine is in operation, removed or can be used, this is an advantage that none of the previously known blueprint machines having. The invention is shown in ίο the drawing, for example:

Abb. ι Längsschnitt,Fig. Ι longitudinal section,

Abb. 2 Querschnitt.Fig. 2 cross section.

Der Glaszylinder α ist an seinen beiden offenen Enden in bekannter Weise in je einen Ring b, c eingesetzt, der, zweckmäßig aus Metall, innen mit elastischen Einlagen versehen ist, und nach außen zweckmäßig in der Form eines Dreiecks d, e ausgebildet ist. Diese Ringe b, c erhalten ihre Führung in den Rollen f", f", die in den Innenseiten der beiden Gestellrahmen g, h angeordnet sind. Der Antrieb des Glaszylinders α kann sowohl direkt von demselben sowie aber auch von den Rollen f", f" erfolgen. An den beiden Gestellrahmen g, h sind oben die beiden Traversen i, i' von beliebigem Querschnitt befestigt in der Weise, daß .beide Traversen durch den offenen Glaszylinder hindurchgehen und an dem jeweiligen Gestellrahmen befestigt sind. An diesen Traversen i, i' sind die elektrischen Bogenlampen k, k'" leicht lösbar angeordnet in der Weise, daß die Lampen auch während des Betriebes leicht auszuwechseln sind. Die Stromzuführung zu den Lichtquellen erfolgt durch die Leitung/, die zweckmäßig an eine der beiden Traversen angeklemmt sein kann, die Zuführung zu den Lampen selbst erfolgt durch die Steckkontakte m. Die Belüftung wird durch die bekannte Anordnung von Ventilatoren erreicht.The glass cylinder α is inserted at its two open ends in a known manner in a ring b, c each, which, suitably made of metal, is provided with elastic inserts on the inside, and is suitably designed on the outside in the shape of a triangle d, e . These rings b, c get their guidance in the rollers f ", f", which are arranged in the inner sides of the two frame frames g, h . The drive of the glass cylinder α can take place both directly from the same as well as from the rollers f ", f" . At the top of the two frame frames g, h , the two traverses i, i ' of any cross-section are attached in such a way that both traverses pass through the open glass cylinder and are attached to the respective frame. The electric arc lamps k, k '"are easily detachably arranged on these traverses i, i' in such a way that the lamps can easily be replaced even during operation Both crossbars can be clamped, the supply to the lamps themselves takes place through the plug contacts M. The ventilation is achieved by the known arrangement of fans.
