Die Erfindung betrifft eine Vorrichtung, mit Hilfe deren die in elektrischen Reklamebeleuchtungsapparaten angeordneten Lampen in ganz bestimmter Weise einzeln nacheinander in zugehörigen Gruppen eingeschaltet und die Gruppen im ganzen gleichzeitig ausgeschaltet werden können. Eine solche Schaltvorrichtung besteht in bekannter Weise z. B. aus einer Platte, mit deren drehbarer senkrechterThe invention relates to a device with With the help of which the lamps arranged in electric advertising lighting apparatus in in a very specific way turned on individually one after the other in associated groups and the Groups as a whole can be switched off at the same time. Such a switching device consists in a known manner z. B. from a plate, with its rotatable vertical

As soon as the sliding contacts of the contact arm are on a segment group,

Gemäß der Erfindung ist der Kontaktarm um seine Längsachse drehbar · gelagert, und er trägt auf mehreren Seiten Schleifkontakte;According to the invention, the contact arm is rotatably mounted about its longitudinal axis, and it has sliding contacts on several sides;

Damit die Drehung des Kontaktarmes von selbst erfolgt, kann derselbe Zahnräder tragen, die mit auf der Kontaktscheibe befestigten Zahnsegmenten o. dgl. zeitweise in Berührung kommen. . 40;Particularly peculiar lighting effects can be achieved. So that the rotation of the contact arm takes place by itself, the same can carry gears that are attached to the contact disk Tooth segments or the like come into contact at times. . 40;

Ein Uhrwerk 1 (Fig. 3) bewegt die Welle 2, welche die mit den Kontakten versehene : Platte 3 durchgreift. Auf der Platte 3 sind 55 die Segmente 4 konzentrisch angeordnet, und darüber bewegt sich der an der Welle 2 befestigte Kontaktarm 17. Dieser Kontaktarm / trägt die Schleif federn 6, welche die Segmente 4 berühren. Damit der Strom nicht 60, in das Triebwerk gelangt, ist auf die Welle 2 ' eine isolierende Buchse 7 aus Holz, Fiber o. dgl. aufgesteckt, die von einer Metallhülse 8 um- ' schlossen wird, welch letztere den Kontaktarm V] trägt.

The segments 4 are concentrically arranged on the plate 3, and the contact arm 17 attached to the shaft 2 moves above it. So that the current does not get into the engine, an insulating bushing 7 made of wood, fiber or the like is attached to the shaft 2 ' , which is enclosed by a metal sleeve 8, the latter of which carries the contact arm V]. The 65 rail 9 is used for the return line, at the free end of which the connection. Conclusion 10 (Fig. 3) is attached. ■ - /:

Claims

Lamps 15 arranged in a compartment together represent a group. In a group, the lamps can be separated from one another by inserts 14 so that they can also light up individually one after the other within the group. '| So that the lamps in a group can all be partially or partially turned on alternately at the same time, the contact arm is arranged to be rotatable. B .; from former tube 17, which rotates on axis 161. The tube carries the sliding contacts 6 and, according to the illustrated embodiment, one row on each of four sides; however, the rows are different from each other in terms of the number of brushes and the arrangement thereof. On the tube 17 a star wheel 18 (Fig. 3) and on the rail 9 ao a stop 19 is attached so that a tooth of the; Star wheel 18 is detected by the stop 19, while the Kontaktami! moves under 'the rail. As a result, the contact arm turns around after each rotation; the axis 2 a self-rotation by 90 °, so each time a new row of sliding contacts is connected to the circuit and the latter from? itself is constantly changing. You can also move the stop 19 out of the path of the wheel 18 and cancel the shift change. '. . As FIGS. 4 and 5 show, the stop 19 can be replaced by toothed segments 21, 22, 23 with different numbers of teeth and the star wheel by a toothed wheel 20. Depending on whether the toothed segment 21, 22 or 23 is used in j the gear is engaged, the same circuit returns after every fourth, second or single revolution. The segments can be shifted in the guides 24, and this shift can also be brought about automatically and automatically. »! . Patent-A ν Proverbs:

1. Switching device for electrical lighting apparatus, ä Characterized in that the contact arm (17) rotatable and ■ provided with several different rows of sliding contacts (6) so that by rotating the contact arm around its longitudinal axis, the switching

; is changed wisely.

2. Switching device according to claim 1, characterized in that the contact arm a star wheel (18)! carries over which,.

z. B. on the shift rail (9), a stop (19) is attached so that the latter after each rotation of the contact arm around the axis (2) the star wheel (18) around one tooth : turns further and brings the next row of sliding contacts into effect.

3. Switching device according to the claims ι and 2, characterized in that a gearwheel is on the contact arm (20) and below in guides (24) displaceable tooth segments with one another different number of teeth (21, 22, 23) are arranged, so that depending on the setting of the segments, the setting of the brush rows (6) can be changed.
