Patentirt im Deutschen Reiche vom l. August 1890 ab.Patented in the German Empire from l. August 1890.

Vorliegende Erfindung hat den Zweck, zwei Kohlenspitzen immer in derselben Entfernung von einander zu halten, wie es namentlich bei Bogenlampen nothwendig ist.The present invention has the purpose of having two coal tips always at the same distance to keep from one another, as is especially necessary in the case of arc lamps.

Sie unterscheidet sich von den bisher gebräuchlichen durch ihre grofse Einfachheit und Dauerhaftigkeit, verbunden mit einer grofsen Empfindlichkeit. Sie ist sowohl für den Verbrauch von Gleichstrom als auch'Wechselstrom geeignet.It differs from the previously used ones in its great simplicity and Durability combined with great sensitivity. She is both for consumption of direct current as well as alternating current.

Fig. ι ist eine Seitenansicht, Fig. 2 eine Vorderansicht und Fig. 3 der Grundrifs derselben. Fig. 2 a, 4 und 5 stellen die unteren Kohlenhalter dar.Fig. 1 is a side view, Fig. 2 is a front view and Fig. 3 is the Grundrifs of the same. Figs. 2a, 4 and 5 show the lower carbon holders.

Die Vorrichtung wird aus zwei Platten von Gufseisen oder Kupfer gebildet, zwischen denen die einzelnen arbeitenden Theile sich befinden. Der eine Pol ist mit der Masse der Vorrichtung verbunden, der andere befindet sich an dem unteren Kohlenträger, welcher von dem Gestell isolirt ist. Eine Zahnstange A, Fig. 1 und 2, welche die obere Kohle trägt, greift in ein kleines Zahnrad E ein; dieses ist fest mit einem grofsen, auf seinem ganzen Umfang gleichmäfsig gezahnten Rad F verbunden und beide sitzen lose auf der Welle B. Oberhalb des Zahnrades E liegt eine Achse G, welche den Hebelarm H trägt, an dem der Eisenanker / befestigt ist. Auf diese Achse G ist das Zahnsegment P gekeilt, welches mit dem Zahnrad F in Eingriff gebracht werden kann, je nachdem der Anker J in die Spule K hineingezogen wird oder austritt.The device is formed from two sheets of cast iron or copper, between which the individual working parts are located. One pole is connected to the earth of the device, the other is on the lower coal support, which is isolated from the frame. A rack A, Figs. 1 and 2, which carries the upper carbon, meshes with a small gear E ; this is firmly connected to a large, evenly toothed wheel F over its entire circumference and both sit loosely on the shaft B. Above the gear E there is an axis G which carries the lever arm H to which the iron anchor / is attached. The toothed segment P, which can be brought into engagement with the gearwheel F , is wedged on this axis G , depending on whether the armature J is drawn into the coil K or emerges.

Diese Spule K ist aus feinem Draht gewickelt und zu den Polklemmen der Lampe in Nebenschlufs gelegt. (Man kann auch auf die Spule dicke Windungen aufbringen, die von dem Hauptstrom durchflossen werden, und sie so mit Differential- oder Hülfswirkung arbeiten lassen.) Die theoretische Form dieser Spule und ihres Ankers ist die kreisförmige; nur die Einfachheit der Ausführung hat die abweichenden Formen dieser Glieder bedingt.This coil K is wound from fine wire and connected to the lamp pole terminals in a shunt. (You can also put thick turns on the coil, through which the main current flows, and thus let it work with differential or auxiliary effect.) The theoretical shape of this coil and its armature is circular; only the simplicity of execution has caused the different forms of these members.

Die Vorrichtung arbeitet folgendermafsen: Ist sie, wie in den Zeichnungen dargestellt, in Ruhe, so wird der Anker (/,.■ Fig. 1 und 2) durch keine Kraft gehoben und tritt folglich durch sein eigenes Gewicht so weit aus der Spule, bis er sich auf die Stützschraube L legt. Bei dieser Stellung hat der Anker das Segment P, welches mit ihm auf der Achse festsitzt, zum Eingriff mit dem Zahnrad F gebracht und diesem eine Drehbewegung im Sinne des Uhrzeigers (Pfeil a) gegeben. An dieser Bewegung des Rades F nimmt auch das mit diesem auf derselben Welle sitzende kleine Zahnrad E theil, welches infolge dessen die Zahnstange A um ein gewisses Stück hebt. Die obere Kohle ist also um das für die Beleuchtung nöthige Mais gestiegen. Im Augenblick des Stromschlusses berühren sich die Kohlen nicht, der Strom kann also nur durch die feinen Windungen der Spule k gehen, was zur Folge hat, dafs der Anker heftig in dasselbe hineingezogen wird und .folglich das Segment P in Bewegung setzt. Dieses gelangt infolge dessen aufser Eingriff mit dem Rad F^ letzteres wird frei und erlaubt der Zahnstange infolge ihres Eigengewichtes herabzugehen und die Berührung der Kohlen herbeizuführen.The device works as follows: When it is at rest, as shown in the drawings, the armature (/, he lies down on the support screw L. In this position, the armature has brought the segment P, which is stuck with it on the axis, into engagement with the gearwheel F and given it a clockwise rotation (arrow a) . In this movement of the wheel F, the small toothed wheel E , seated on the same shaft, also takes part, which consequently lifts the toothed rack A by a certain distance. The upper coal has thus risen by the maize necessary for lighting. At the moment of the current connection the carbon brushes do not touch each other, so the current can only pass through the fine turns of the coil k , with the result that the armature is violently drawn into it and consequently sets the segment P in motion. This arrives as a result of this engagement with the wheel F ^ the latter is released and allows the rack to go down due to its own weight and to bring about the contact of the coals.

significant reduction in the force of the coil k . As a result of this, the armature, due to its own weight, is immediately allowed to fall back into its first-described rest position, and by switching on segment P , through the intermediary of the large gear F and the small gear E, the rack A is raised and the carbon brushes are sufficiently removed from each other to cause the arc to let glow. This distance between the coals is, however, a little smaller than that when the pace is normal. The current flows through the coals, consumes them somewhat and thus increases the distance between their tips. This gives the arc greater resistance, which on the other hand increases the current in the coil and, as a result, its attractive force. The armature J is tightened again, goes into the coil according to the coal consumption up to a position where the segment P wants to release the wheel F. This position is that of electrical equilibrium, and consequently the point at which the lamp must be adjusted; it corresponds to the correct arc. At the slightest further consumption of the coals, the segment P releases the wheel F, which has prevented the heavy rack from falling down until then, and this tries to turn in the direction of arrow b in order to let the rack go down and the coals to approach . This ■ approach of the carbons, however, reduces the resistance of the arc, and consequently also the current strength of the coil K, which gently lets its core ■ decrease. The same movement is also made by segment P, which engages in wheel F and thus holds it back again until another coal consumption causes the same play. The engagement and the release of the wheel F by the segment P takes place so quickly that the wheel turns only through an angle as small as corresponds to one tooth of its circumference. This angle causes the rack to sink, corresponding to the pitch of the teeth of the wheel F divided by the ratio of the diameters of the wheel F and the gearwheel Έ. This circumstance allows any desired degree of susceptibility to decline to be achieved. In addition, the weight of the wheel F will significantly dampen these various movements due to its inertia.

In spite of the coal consumption, this always ensures the correct distance of the coal tips maintained that tooth by tooth of the wheel F is released and so the Rack sinks gradually lower.

If the work is particularly calm, the anchor will assume its rest position and so on hold the coals at the distance necessary for arcing. These Arrangement is of great advantage, since it automatically avoids fixing, which is the case with none of the arc lamps available to date is the case.

The effect of the regulation mechanism is very powerful and has not yet ensured one previous practical work. The strong execution of all the working parts reduces the influence of accidental bumps.

The coal carriers N, Fig. 2a, 4 and 5, are very simple and durable; the eccentrics O hold the carbon firmly enough and thus avoid any disturbance which is so dangerous for the safe operation of these devices.

What mainly causes the absolute reliability of a smooth gait is the fact, that, contrary to all devices available up to now, gravity is used for this purpose will remove the coals mechanically, while the effect of the current is the Causes the coals to be brought closer to one another.

Patent application:

In the case of sidelights, which are used to enable the coals to converge Due to the gravity of the carbon holder, a toothed locking segment by tightening the Armature of the shunt electromagnet is lifted out of the locked disc, which This anchor is arranged in such a way that when the anchor is released it will fall by virtue of the gravity of the latter, the locking segment falling into the disc rotates it and this forms the arc.
