KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die bekannten Projectionsapparate für Panoramen, d. h. für Projicirung eines fortlaufenden Bildes auf eine cylindrische Flache, wobei der Apparat in dem Mittelpunkt des Cylinders befindlich ist, haben den grofsen Nachtheil, dafs es bei der Verwendung von einer Anzahl unabhängig von einander arbeitender Lampen fast unmöglich ist, diese mit durchaus gleicher Helligkeit brennen zu lassen, was für das gleichmäfsige Projiciren eines Panoramabildes unbedingt, nöthig ist, wenn anders sich nicht die verschiedenen Bildtheile infolge ihrer verschiedenen Beleuchtung deutlich von einander abgrenzen und den Eindruck eines fortlaufenden Bildes zerstören sollen. Diesem Uebelstande nun wird gernäfs vorliegender Erfindung dadurch abgeholfen, dafs für sämmtliche, zu einem Ganzen vereinigte Apparate eine gemeinsame centrale Lichtquelle angeordnet ist, welche in Form eines Lichtkranzes alle einzelnen Bilder gleichmäfsig erleuchtet.The known projection apparatus for panoramas, d. H. for projecting a continuous Image on a cylindrical surface, with the apparatus in the center of the cylinder are located have the great disadvantage that it is when using a number It is almost impossible to work lamps independently of one another, to do so with lamps that are entirely the same To let the brightness burn, what a uniform projecting of a panorama picture it is absolutely necessary if the different parts of the picture do not differ as a result of their different Clearly differentiate lighting from each other and give the impression of a continuous Destroy the image. This inconvenience is now complied with by the present invention remedied by the fact that there was one common device for all the apparatuses that were combined into a whole central light source is arranged, which all individual in the form of a light ring Images evenly illuminated.

Acht oder mehr einzelne zu einem Ganzen verbundene Projectionsapparate sind um das Centrallicht B auf der Säule C angeordnet, wie Fig. ι der beiliegenden Zeichnung ersehen lä'fst. Jeder Apparat besteht aus einer Condensationslinse Z), einem achromatischen Objectiv E und einem vertical verschiebbaren, mit zwei oder mehr Oeffnungen für di6 Diapositive oder Transparente G versehenen Plattenhalter F. Jeder Apparat kann für sich radial oder winklig zu dem Centrallicht eingestellt werden. Die rechtwinklige Oeffnung eines jeden Condensators ist mit seitlich verstellbaren Metallstreifen HH belegt, um den Rand der Oeffnung so begrenzen zu können, dafs die Ränder der einzelnen Projectionen einander genau decken. Diese Regulirung geschieht mittelst der Schrauben //.Eight or more individual projection apparatuses connected to form a whole are arranged around the central light B on the column C , as can be seen in FIG. 1 of the accompanying drawing. Each apparatus consists of a Condensationslinse Z), an achromatic object-glass E and a vertical movable, with two or more openings for di6 slides or Transparent G disc holder provided F. Each apparatus may be adjusted for radially or at an angle to the Central light. The right-angled opening of each condenser is covered with laterally adjustable metal strips HH in order to be able to limit the edge of the opening in such a way that the edges of the individual projections exactly coincide. This regulation takes place by means of the screws //.

Das Objectiv E ist ausziehbar und mit Einstellschraube versehen. Abschattirte Glas- oder Gelatinescheiben können zur Abtönung der Beleuchtung vor die Objective gleichzeitig eingestellt werden.The Objectiv E is extendable and has an adjusting screw. Shaded glass or gelatin panes can be placed in front of the objective at the same time to shade the lighting.

Sämmtliche Plattenhalter werden gleichzeitig mittelst Zahnstange K, Zahnräder L L und Handgriffes M bewegt. Als Centrallicht wird der in Fig. 2 in Seiten- und Oberansicht veranschaulichte Kalkbrenner verwendet.All plate holders are moved simultaneously by means of rack K, gear wheels LL and handle M. The lime burner illustrated in side and top view in FIG. 2 is used as the central light.

Es wird eine Anzahl von der Mischkammer Q. aus gespeister Knallgasdüsen O O um den KaIkcylinder P angeordnet, und der Kalkcylinder in der Hülse R wird mittelst der Schraube 5 entsprechend dem Verbrauch vorgeschoben. A number of oxyhydrogen gas nozzles OO fed by the mixing chamber Q. are arranged around the lime cylinder P, and the lime cylinder in the sleeve R is advanced by means of the screw 5 in accordance with the consumption.

Es entsteht auf diese Weise ein Lichtband, das alle Condensationslinsen gleichzeitig beleuchtet. This creates a band of light that illuminates all condensation lenses at the same time.
