Description

Gegenstand der Erfindung ist eine Weiterbildung der in dem Patent 388574 geschützten Erfindung. Neu ist die Verwendung eines an •ler Peripherie einer umlaufenden Scheibe angebrachten, aus beispielsweise drei Segmenten bestehenden, besonders geschliffenen Glaskranzes, der dazu dient, ein schmales Lichtband der Durchbrechung in der λ'er schluß scheibe nachzufahren. Die Anzahl der Segmente muß to gleich der Anzahl der bogenförmigen Durchbrechungen.in der Verschlußscheibe sein, damit beide Scheiben fest auf derselben Welle aufgebracht werden können. Außerdem bietet die Verwendung mehrerer Segmente den Vorteil, daß der Schliff so, wie er für den vorliegenden Zweck benötigt wird, bedeutend einfacher genau ausgeführt werden kann, als dies bei Verwendung eines einzigen Glaskranzes möglich wäre.The subject of the invention is a further development of the patent 388574 protected Invention. What is new is the use of an attached to the • periphery of a rotating disc, For example, a specially cut glass ring consisting of three segments, which serves to create a narrow band of light through the opening in the λ'er circuit to follow. The number of segments must be equal to the number of arcuate openings in the locking disc so that both discs are firmly attached to the same shaft can be. In addition, the use of several segments has the advantage that the cut as it is for the present Purpose is required, can be carried out with accuracy significantly easier than this Use of a single glass wreath would be possible.

so Zur Veranschaulichung der Anordnung dienen die Abb. 1 bis 4. Abb. 1 stellt den Apparat im Aufriß, Abb. 2 im Seitenriß (von rechts nach links gesehen), Abb. 3 im Grundriß dar, während Abb. 4 die bereits erwähnte Scheibe mit Glaskranz in der Vorderansicht zeigt, ι bedeutet die im Uhrzeigersinne umlaufende, aus dünnem Blech hergestellte .Scheibe, welche von zwei konzentrischen Ringen getragen wird, die in geeigneter Weise miteinander und mit einer Nabe verbunden sind. 2 sind drei spiralförmig gekrümmte feine Durchbrechungen der Scheibe, deren größter Abstand voneinander der Höhe eines Teilbildes entspricht. 3 ist das von rechts nach links laufende Bildband. Vor der Scheibe befindet sich das Objektiv 4; 5 und 6 sind zwei Lagerböcke, welche zur Aufnahme der Welle 9 dienen. Diese trägt die Scheibe 1, das Stirnrad 11, die Antriebsschnurscheibe 24 sowie die Scheibe 8, an deren Rande der aus drei besonders geschliffenen Segmenten 7 bestehende Glaskranz befestigt ist. In Abb. 4 ist das rechts oben gezeichnete Segment an zwei in der Nähe der beiden Stirnflächen liegenden Stellen längs a, b bzw. a1, b1 geschnitten. Die dadurch entstehenden Schnittfiguren sind in die Zeichenebene umgelegt und stellen zwei kongruente gerade Trapeze dar, die aber entgegengesetzte Neigung haben. 10 in Abb. 2 deutet die Mittelachse des Strahlenbündels an. Im Eingriff mit 11 befindet sich das Stirnrad 12, welches mit der auf den Lagerböcken 14, 15 ruhenden Welle 13 fest verbunden ist. Ebenfalls auf dieser sitzt der Stellring 25 und das Winkelrad 16, welches in das Winkelrad 17 eingreift. Dieses trägt auf seiner Nabe das Schnurrad 20 und ist mit dem Antriebsrädchen 19 für das Bildband durch den Zapfen 18 verbunden. Zur Aufnahme des Zapfenlagers dient der Bügel 21, der auch die um 22 drehbaren Führungsrollen für das Bildband sowie die -— nicht gezeichnete — Fensterführung trägt. Die Wirkungsweise des Apparates ist die. daß die Drehbewegung der Welle 9 durch die Stirnräder 11 und 12 sowie die Winkelräder 16 und 17 auf die Antriebsrolle 19 übertragen wird und das Filmband die nach Größe und Richtung erforderliche Bewegung erhält. Die Ablenkung des durch 10 repräsentierten Strahlenbündels geschieht in für den vorliegenden Zweck besonders vorteilhafter Weise, da sich die Lichtlinie — wie leicht ersichtlich — der Spiralbogenform der Durchbrechung anschmiegen muß.Fig. 1 to 4 serve to illustrate the arrangement. Fig. 1 shows the apparatus in elevation, Fig. 2 in side elevation (seen from right to left), Fig. 3 in plan view, while Fig. 4 shows the disk already mentioned with a glass rim in the front view, ι means the clockwise circumferential, made of thin sheet metal .Scheibe, which is carried by two concentric rings that are suitably connected to each other and to a hub. 2 are three spirally curved fine perforations in the disk, the greatest distance from each other corresponding to the height of a partial image. 3 is the illustrated book running from right to left. The lens 4 is located in front of the disk; 5 and 6 are two bearing blocks which are used to accommodate the shaft 9. This carries the disk 1, the spur gear 11, the drive cord disk 24 and the disk 8, on the edge of which the glass ring consisting of three specially cut segments 7 is attached. In Fig. 4, the segment drawn at the top right is cut at two points in the vicinity of the two end faces along a, b and a 1 , b 1 , respectively. The resulting sectional figures are laid down in the plane of the drawing and represent two congruent straight trapezoids, which, however, have opposite inclinations. 10 in Fig. 2 indicates the central axis of the beam. In engagement with 11 is the spur gear 12, which is firmly connected to the shaft 13 resting on the bearing blocks 14, 15. The adjusting ring 25 and the angle wheel 16, which engages in the angle wheel 17, are also seated on this. This carries the cord 20 on its hub and is connected to the drive wheel 19 for the picture book by the pin 18. The bracket 21 serves to accommodate the journal bearing and also carries the guide rollers for the picture book, which can be rotated by 22, as well as the window guide (not shown). The mode of operation of the apparatus is this. that the rotational movement of the shaft 9 is transmitted through the spur gears 11 and 12 and the angle gears 16 and 17 to the drive roller 19 and the film tape receives the movement required in terms of size and direction. The deflection of the bundle of rays represented by 10 takes place in a manner which is particularly advantageous for the present purpose, since the line of light - as can easily be seen - must nestle against the spiral arc shape of the opening.
