Innovations in electric lamps.

Patented in the German Empire on November 2nd, 1884.

The innovations concern;

ι. the way in which the movement of the iron cores is transferred to the carbon holder,

2. The arrangement of the circuit in such a way that one who is connected to the current Regulator conducts the current around the iron cores in such a way that, if the arc is too large, it dissolves approach, but if it is too small, move away from each other, which device has the purpose, to be able to use the lamp for variable currents.

The lamp is in Figs. 1, 2 and 3 in three views, and the circuit is schematic illustrated by FIG.

On the shaft α is the roller b, on which the iron cores ee _{x, which} are immersed in the solenoids s S ₁ , hang on cords or chains k. The iron cores e U ₁ carry the rollers T ₁ r ₂ , over which the chains or cords t ί _{τ are} placed.

Since the cords with the supporting one end to the eyes 0 O ₁ and the other to the movable, the brush holder 1I _1, m to the connecting columns m _x m _{3 3} m _t guided webs η H are fixed to _1, the brush holder are / 1 ₁ cover twice as great as the way the iron cores e e _r

The power line illustrated in Figure 4 is as follows:

The current which ^{enters the lamp at + m} and leaves it at - finds the three paths hik at u .

Of these routes, provided that the line is not interrupted between the coal tips, Zz leads through the iron core e, the carbon holder /, the carbon rods c C ₁ , the carbon holder Z ₁ , the iron core e _x , around the iron core ρ in many Turns around to the node x, where it divides _{into the three paths Zz 1} Zz ₂ Zz _8.

The paths Zz ₂ Zz ₃ lead in many turns around the iron cores e ε _λ to the node ι and from there directly to the negative pole; the path Zz ₁ can only be passed by the current if the contact tongue d is either at (I ₁ or at d. _2. In the first case the current goes through Zz'j into the spiral Z _{1 of} the iron core e _u in the second case through h " ₁ into the spiral Z _{2 of} the iron core e and meets at \ with Zz ₂ and Zz ₈ .

The path i leads, provided that the spring ν is not attracted by the iron core ρ , but assumes the position shown in Fig. 4, to the node y and from here through the spiral Z ₂ to the node \.

The path k, which is always open to the current, has a considerable resistance and leads through the solenoid w to the node ^.

When the electricity comes into the lamp, there are two possible cases:

• i. the coal tips stand apart from each other;

2. the coal tips touch.

In the former case, the process is as follows:

Of the three paths that h is interrupted, the current only finds i and k in front of it and uses it, passing the significant resistance

with h ₂ h ₃

the line k evades, the line i, thereby the iron core e is attracted by the solenoid L ₂ until the coal tips meet.

Because of the contact with the coal tips, the path h is no longer interrupted, the current goes through the coal, around the iron core jp, which as a result becomes magnetic and, by attracting the spring ν , interrupts the line i.

Once at χ , the current goes through line h. ₂ h _z around the iron cores ee _x and pulls both downwards with the same force.

The line H ₁ goes through the spring /, the contact d _x and through h \ in the solenoid Z ₁ and from there to \, where it is
reunited.

Since in this way two parts of the current are conducted around the iron core e _x , while the iron core e is only encircled by one part, the core e _x is drawn downwards with greater force, and the arc is formed.

Since the resistance in the main line has increased as a result of the removal of the carbon tips, part of the current passes through the line kw , the solenoid w draws in the iron core q and removes the contact dd _x , so that now both iron cores e again O ₁ can be pulled down with the same force.

The larger the arc, the greater the amount of current that goes through the solenoid w , and the deeper the contact tongue d will come to rest.

The tension of the spring /, which counteracts the attractive force of the solenoid w , is measured in such a way that, as soon as the arc has reached the maximum of the permissible magnitude, the contact dd _{2 is} established and the current H ₁ through h '\ into the solenoid i ₂ is directed.

Since, in this case, the iron core e encircles two parts and the iron core e _x only one part of the current, e is drawn downwards and the size of the arc is reduced again.

In this way the current is switched by the regulator w qf in such a way that if the arc is too large it pulls the core e downwards and if the arc is too small it pulls the iron core e _x downwards with greater force.

In the second case the current comes into the lamp and the coal tips touch each other.

In this case, the spring ν is immediately attracted by the electromagnet and the power line i is interrupted; the current will then, as described above, pass through the solenoid J ₁ , pull the iron core 'e _x downwards and produce the arc.
