Gegenstand der Erfindung ist eine Regulirvorrichtung für elektrische Lichtbogenlampen. Zu diesem Zweck wird der untere oder negative Kohlenstab feststehend und der obere oder positive Stab bezw. dessen Halter durch ein Rohr oder eine Führung frei verschiebbar angeordnet, woran eine elastische Schlinge oder ein Ring an einer Stelle so gehalten wird, dafs _durch diesen Ring oder diese Schlinge die positive Kohle oder deren Halter hindurchgeht. Die gegenüberliegende Stelle dieser Schlinge oder des Ringes ist mit der Armatur eines Elektromagnetes in Verbindung, z. B. durch ein Verbindungsglied, dessen anderes Ende mit dem einen Arm eines Hebels verbunden ist, der seinen Drehpunkt an einem Halter hat. Der andere Arm dieses Hebels ist mit einer Armatur versehen, worauf ein Elektromagnet oder ein Solenoid einwirkt. Wenn diese Armatur von dem-Magnet angezogen wird, so wird der elastische Ring gehoben und schief gestellt und dadurch die Kohle eingeklemmt und um die nöthige Strecke hochgehoben, so dafs der Lichtbogen sich bilden kann. Wenn dagegen die Armatur losgelassen wird, so zieht sich der elastische Ring zusammen und gelangt aus seiner Schieflage heraus, so dafs dann die Kohle frei durch ihn hindurchschlüpfen kann.The invention relates to a regulating device for electric arc lamps. For this purpose, the lower or negative carbon rod becomes fixed, and the upper one or positive rod respectively. its holder can be moved freely through a pipe or a guide arranged, on which an elastic loop or a ring is held in one place so that _Through this ring or this loop the positive carbon or its holder passes. The opposite point of this loop or ring is one with the armature Electromagnet in connection, for. B. by a link, the other end with is connected to one arm of a lever which has its pivot point on a holder. The other arm of this lever is fitted with a fitting, whereupon an electromagnet or a solenoid acts. If this armature is attracted by the magnet, so the elastic ring is lifted and placed at an angle, thereby pinching the coal and raised the necessary distance so that the arc can form. if on the other hand, if the fitting is released, the elastic ring contracts and arrives out of its misalignment, so that the coal can then slip freely through it.

Die elastische Schlinge wird am besten in einer geneigten Lage angeordnet und mehrere Kohlenstäbe können in der vorbeschriebenen Weise neben einander in einem Ring oder nach Belieben in einer einzigen Lampe angeordnet werden.The elastic loop is best placed in an inclined position and several Carbon rods can be next to each other in a ring or in the manner described above can be arranged at will in a single lamp.

Fig. ι beiliegender Zeichnung stellt eine Vorderansicht einer mit einem Paar Kohlenstäben versehenen elektrischen Lampe dar. Dieselbe ist in Fig. 2 in Seitenansicht und in Fig. 3 im Grundrifs veranschaulicht.Fig. Ι the accompanying drawing shows a front view of one with a pair of carbon rods provided electric lamp. The same is in Fig. 2 in side view and in Fig. 3 illustrates in outline.

Fig. 4 zeigt eine nach demselben System construirte, mit zwei Paar Kohlenstäben versehene Lampe, wobei die Kohlenstäbe sich so einstellen lassen, dafs sie entweder zusammen oder einzeln oder ein Paar nach dem anderen zum Abbrennen gelangen. Fig. 5 zeigt eine Seitenansicht dieser Einrichtung und Fig. 6 eine Lampeneinrichtung, worin zwei obere Kohlenstäbe durch ihre Schwere und ein einzelner unterer, durch ein Gegengewicht ausbalancirter Kohlenstab durch ein Solenoid und einen elastischen Ring zur Einstellung gelangt.Fig. 4 shows one constructed according to the same system, provided with two pairs of carbon rods Lamp, whereby the carbon rods can be adjusted so that they either go together or burn individually or in pairs. Fig. 5 shows a Side view of this device; and Fig. 6 shows a lamp device in which two upper carbon rods by their gravity and a single lower one, balanced by a counterweight Carbon rod is adjusted by a solenoid and an elastic ring.

Bei dieser letzteren Einrichtung geschieht die Einstellung des unteren Kohlenstabes, indem die oberen Kohlenstäbe schneller als der eine untere abbrennen und durch ihre Schwere herabsinken, in längeren Intervallen. Eine Klemmschraube a, Fig. 1, für den Drahtanschlufs sitzt an dem die untere Kohle b tragenden Metallrahmen p. Die andere von p isolirte Klemmschraube c. ist mit dem einen Ende einer dicken Drahtwickelung, die um das Solenoid d. herumgelegt ist, verbunden, dessen Eisenkern oder Eisenkerne e sich an einen Hebel f anschliefsen, der den oberen. Kohlenstab trägt. Dieser Hebel ist so eingerichtet, dafs sein äufserer Arm nach Bedarf sich verlängern oder verkürzen läfst, z. B. je nach der Stärke· des elektrischen Stromes, der die Drahtwicke-In this latter device the adjustment of the lower carbon rod takes place in that the upper carbon rods burn down faster than the lower one and, due to their weight, sink down at longer intervals. A clamping screw a, Fig. 1, for the wire connection sits on the metal frame p carrying the lower carbon b. The other clamping screw, isolated from p, c. is connected to one end of a thick wire wrap around the solenoid d. is lying around, connected, the iron core or iron cores e of which adjoin a lever f which controls the upper. Carrying coal stick. This lever is arranged in such a way that its outer arm can be lengthened or shortened as required, e.g. B. depending on the strength of the electric current that

ment d , or depending on the machine to be used, or depending on the number of lamps that are in the power line.

Such a lengthening or shortening can be effected by means of the screws / '/' will.

The solenoid d is also provided with a winding of thin wire which, contrary to the thicker wire, offers a sufficiently strong resistance to the electric current that a certain part of the electric current is rendered inactive when it passes through the wire winding of the solenoid or electromagnet. The lever f has its fulcrum on the holder piece g, and a strong adjustable spring h is connected to the lever / by means of a connecting link i , so that in the resting state the iron core e is pulled out of the coil d by a suitable distance and the coal tips are in contact can occur.

The end of the lever / carries a connecting link z, on which the upper carbon holder k is held by means of a ring / made of rubber or other elastic material.

One point of this ring / is connected to the connecting member i by pins or clamps, and the ring is of such a size that the carbon holder k can slide down through it as a result of its own weight when the tension in the ring ceases because the electric current ceases, or becomes weaker because it finds greater resistance as the arc grows longer. The other end of this ring / is held in place by a curved arm / ', the height of which can be changed by means of the adjusting nuts rr.

These lamps can be set up with one, two or three pairs of carbon rod holders and one or more levers f can be connected to the iron core of the solenoid or the armature of an electromagnet. For example, FIGS. 4 and 5 show a lamp with two pairs of rods and FIG. 6 shows a lamp with three carbon rods, two upper ones and one lower one, which is then adjustable.

The lamps can be set up to function individually or in groups as required. The lamp frame is supported by a table s .

qq are rings from which the lamp can be hung.

The lamp works as follows:

As long as no current passes through the lamp, the carbon tips are in contact with each other. When the current now circulates through the windings of the solenoid d , the iron core e is pulled down and the opposite end of the lever f is thereby raised. The elastic ring /, which is connected to this lever by means of the link i , is thereby raised at one end and in doing so grasps the carbon or its holder and raises it by the amount necessary for the formation of the arc. As the carbon rods are consumed and the resistance in the arc increases, the force with which the lever / elastic ring / pulls decreases, and as a result this ring contracts and allows the carbon holder k to sink down until the required carbon spacing has been reached. Then the ring is again attracted to the iron core e by the solenoid d and so on

The use of such an elastic ring offers the advantages that after the first lifting of the carbon rods, they do not come into contact again, if so not every stream stops. Therefore, when using such elastic rings, the Carbon rods according to the degree of tension exerted by the lever on the rings, slide down quickly or slowly, depending on the strength of the current a greater or greater lower is.

With this expansion and contraction of the ring, the carbon rods become automatic . kept apart at the most suitable distance for the formation of the arc and thereby every flickering of the light, as one usually perceives it with such lamps can be avoided.

The required length of the arc is very easy to regain. The spring h on the lever f , which counteracts the attraction of the solenoid core e , can also be adjusted according to the strength of the current or the machine used.

Patenτ claim:

In the case of an electric lamp that is provided with one or more pairs of carbon rods and wherein a solenoid or electromagnet is used to separate and adjust said carbon rods causes the application of a clamping ring / that of the said solenoid or Electromagnet is influenced and made of rubber or some other elastic or pliable Mass exists.
