Patentiert im Deutschen Reiche vom 9. April 1907 ab.Patented in the German Empire on April 9, 1907 .

Gegenstand der Erfindung ist ein Verfahren zum Aus- und Einschalten der Saalbeleuchtung in Räumen zum Vorführen lebender Photographien sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for switching the hall lighting off and on in rooms for showing living photographs and an apparatus for carrying out this process.

Das Verfahren besteht darin, daß der elektrische Strom für die Saalbeleuchtung durch den Kinematographen so lange unterbrochen gehalten wird, als die FortschaltvorrichtungThe procedure consists in that the electric current for the hall lighting through the cinematograph is kept interrupted as long as the indexing device

ίο mindestens die zum Vorführen der Bilder erforderliche Geschwindigkeit besitzt. Eine weitere Ausbildung des Verfahrens besteht darin, daß der elektrische Strom für die Saalbeleuchtung auch beim Abreißen des Bildbandes durch eine von dem gespannten Bildbande bis dahin gesperrte Schaltvorrichtung wieder selbsttätig eingeschaltet wird. Durch das neue Verfahren soll, bei eintretendem Brand oder bei Zufällen, die einen solchen verursachen können, eine Beunruhigung des Publikums schon im Augenblicke der Gefahr verhindert werden.ίο at least what is required to present the pictures Owns speed. A further development of the procedure consists in that the electric current for the hall lighting also when the illustrated book is torn off again by a switching device that has been blocked by the stretched photo band until then is switched on automatically. The new procedure should, in the event of a fire or in the event of coincidences that can cause such a disturbance of the public can be prevented at the moment of danger.

Der vor der Vorführung den Saal beleuchtende elektrische Strom wird nach dem vorliegenden Verfahren dadurch unterbrochen, daß ein Schaltorgan in der Lichtleitung geöffnet wird, sobald ein auf der Drehachse des Kinematographen sitzender Zentrifugalregulator eine bestimmte Drehungsgeschwindigkeit erreicht hat. Der Schalter bleibt so lange geöffnet, als diese Drehungsgeschwindigkeit nicht unter eine bestimmte Grenze herabsinkt. Sollte aber, während der Kinematograph noch hinreichend rasch gedreht wird, das Bildband abreißen, so wird die Saalbeleuchtung wieder dadurch hergestellt, daß ein von dem gespannten Bildbande bis dahin gesperrtes Uhrwerk selbsttätig ausgelöst wird und nunmehr andere Schaltvorrichtungen für die Lichtquellen umsteuert. . .The electric current illuminating the hall before the performance will be according to the present one The process is interrupted in that a switching element is opened in the light pipe becomes as soon as a centrifugal regulator sitting on the axis of rotation of the cinematograph has reached a certain speed of rotation. The switch stays open so long when this speed of rotation does not drop below a certain limit. But it should, while the cinematograph is still is rotated sufficiently quickly, tear off the picture book, so the hall lighting is again produced by the fact that a clockwork that had been locked by the stretched illustrated band until then is automatically triggered and now other switching devices for the light sources reverses. . .

Die zur Durchführung des Verfahrens dienende Vorrichtung ist auf der beiliegenden Zeichnung beispielsweise dargestellt, und zwar zeigt Fig. ι eine Vorderansicht, während Fig. 2 die Seitenansicht eines Kinematographen erkennen läßt.The device used to carry out the process is shown on the enclosed sheet Drawing shown for example, namely Fig. Ι shows a front view, while FIG the side view of a cinematograph can be seen.

Es ist eine doppelte Lichtleitung vorgesehen. In den durch die Klemmen 1 und 13 gehenden Stromkreis 16, 17, 24, 15, welcher die Saalbeleuchtung vor Beginn der Vorführung unterhalt, ist ein Kontakt 2 geschaltet, welcher bei ruhendem Zentrifugalregulator durch dessen Feder F geschlossen ist, indem die verschiebbare Hülse 9 an dem von dem Gestell des Apparates isolierten Bügel 2 anliegt. Sowie der Regulator die zur Vorführung erforderliche Drehgeschwindigkeit erlangt hat, verschiebt sich die Hülse 9, indem sich die Federn F unter der Wirkung der Gewichte B des Regulators durchbiegen, so daß zwischen Hülse 9 und Kontakt 2 keine Berührung mehr stattfindet.A double light pipe is provided. In the circuit 16, 17, 24, 15 going through the terminals 1 and 13, which maintains the hall lighting before the start of the performance, a contact 2 is connected, which is closed by its spring F when the centrifugal regulator is at rest by the sliding sleeve 9 the bracket 2, which is isolated from the frame of the apparatus, rests. As soon as the regulator has attained the rotational speed required for the demonstration, the sleeve 9 shifts in that the springs F flex under the action of the weights B of the regulator, so that there is no longer any contact between the sleeve 9 and the contact 2.

In einer zweiten, durch die Klemmen 18,19 gehenden Lichtleitung (in Fig. 1 punktiert angedeutet), welche die Beleuchtung dann einschalten soll, wenn bei bewegtem Regulator das Bildband zerreißen sollte, sind zwei Bügel 4, 6 eingeschaltet, welche auf dem UmfangIn a second, through the terminals 18,19 outgoing light line (indicated by dotted lines in Fig. 1), which then turn on the lighting if the picture tape should tear when the regulator is moved, there are two brackets 4, 6 turned on, which on the perimeter

Claims

Grind a circular disk 5 made of a non-conductive material. At a Place of the circumference of this disc, a piece of metal 7 is used, which at a certain Position of the disc connects both contacts and closes the current; at all However, the current is interrupted in other positions of the disc 5. To the power supply two special clamping screws are used for the magnet 29.

The disc 5 is part of a clockwork A, which is locked by the tensioned film.

This is done in that a movable plate, which is isolated from the housing, is loosely pressed against the picture tape; but if this tears, the plate touches the housing; the current leading to the windings of the magnet 29 is closed. The armature of the magnet is attracted and triggers the blocking of movement A.

The piece 7 sits on the disk in such a way that, when the clockwork is wound, the bows 6 lie on the non-metallic part of the disc; it is consequently this light guide interrupted when the clockwork is wound. The clockwork must be used for normal operation of the apparatus be raised, d. H. the current that drives the motor can only then be switched on when the movement is wound.

The clockwork does not run down until the film tears. The clockwork, which also serves other purposes, as well as the device that actuates the film not the subject of the invention. As soon as the clockwork begins to run down, it becomes independent whether contact 2 is closed or open, the line 3, 20, 21, 8 through the bracket 4, 6 closed. So there will be the electric lighting fixtures even without any action of the bracket 2 and the sleeve 9 switched on.

The marked device can also be provided with a device which causes the ignition of gas burners located in the auditorium, as soon as the clockwork A is released as a result of the tearing of the illustrated book. In the state of rest, the ignition device exerts a pull on a cord suspended in a hook 11 of a two-armed lever 12. The free end of this lever rests on a lever 10 of the clockwork A, which is lifted when the clockwork is running. Here, the hook 11 lowers, whereby the connection with the suspended cord is released.

With the tearing of the illustrated book it is in every respect the case that it has expired completely is equivalent.

It has already been suggested that when the illustrated book is torn automatically one in the Turn on the lamp placed near the cinematograph in order to carry out the necessary restoration work to be able to start immediately. However, this method differs from the invention in that it is the main purpose of Invention of switching on hall lighting not fulfilled.
