ELECTRlC-ARC LAM P.
SPECIFICATION forming part of Letters Patent N 0. 743,239, dated November 3, 1903- Application filed November 23, 1901. Serial No. 83,490. (No model.)
To all whom it may concern.-
Be it known that I, HUGO BREMER, a subject of the Emperor of Germany, residing at Neheim-on-the-Ruhr, in the Province of Westphalia, Germany, have invented a new and useful Improvement in Electric-Arc Lamps, of which the following is a specification.
My improvement relates to electric arc lamps having one or more pairs of downwardlypointed carbon pencils which are placed parallel or obliquely toward each other.
The special object of the invention is to provide regulating means whereby a portion of the current shunted or diverted from the arc is utilized for setting the regulating mechanism into operation.
In such lamps the position of the arc varies according to the burning away of the carbons either by traveling up or down, while in the ordinary lamp the arc is drawn asunder. The change of position of the arc is arranged to set in operation the feeding mechanism for the carbons, and the means by which such action is effected form the object of my invention.
The invention is illustrated in the accompanying drawings, in which- Figures 1, 2, 3, t, 5, 6, and 7 show various means for carrying out the invention, the views being mainly diagrammatic in character.
In Fig. l is shown an arrangement of a contact-peg 1, which is touched by the ascending are 2. This peg leads, by means of a connecting-wire 3, to the feeding device t, which may be constructed in any suitable manner and serves in proper time when operated upon by the current to feed the carbons so that the latter can drop, together with the are, as, according to the high resistance of the are, part of the current flows from the negative carbon to the contact-peg 1, so this part of the current is sufficient to operate the feeding device. As soon as the carbons are dropped the arc can no more engage the peg and the operation upon the feeding device ceases.
Instead of arranging one peg as described there may be two pegs 5 6, adjustably se= cured to the chamber surrounding the carbon points, the first being connected by a wire 8 to the'carbon-feeding device, the other pegG by a wire 7 to one of the electrodes. The climbing arc will then connect with its edge both pegs 5 6 and cause the feeding device to be released.
In Fig. 3 I have arranged a magnet 10 above the are having a deflecting action upon the arc, blowing it downward and keeping it thus at the carbon points. If now a second magnet is positioned near the are, having also a blowing action on the arc, the same is removed from said magnet with the burning away of the points and approaching the deflecting-magnet 10. The lines of force of the magnetic field cause the arc to be drawn strongly upward. The power of the lines of force increases with the approaching arc and can become so strong that the arc can be torn cit. It is also of advantage to position said deflecting-magnet 10 somewhat sidewise in order to turn the arc sidewise and cause its breaking off. The deflecting agent may also be operated or positioned in such a manner that the blowing action of the magnetic field increases with the approaching are, so that the resistance of the are constantly increases, and the resistance between the electrodes result-ing therefrom acts on the feeding device,'as in the ordinary lamps. However, the power may be also increased, so that a complete tearing oli of the arc takes place, and consequently a relighting and adjusting of the carbon points. As all these arrangements operate very rapidly, the tearing off of the arc would be scarcely perceived. The lamps being established in one circuit are so little influenced by such tearing OK that scarcely a flicker may be seen.
In Fig. i is shown a body 13 above the arc, which expands by the heat of the approaching arc and if connected by a wire 14 with one pole of the regulating device engages the other pole 15 of the same, so that the latter can start.
In Fig. 5 is shown a second-class leader 16, consisting, for instance, of kaolin, magnesium, or the like, which by the heat of the approaching arc gets conductive, allowing them to pass a current sniliciently strong" to start the regulating device, said body getting with the descending are again less conductive.
In Fig. 6 is shown a diaphragm 17, arranged between the electrodes. According to the burning away of the carbons the arc Will be forced outward, traveling round the diaphragm and growing thus longer. The resistance of the are likewise increases, and so the feeding device is again set in action.
In Fig. 7 a device is illustrated showing that the arc in creeping upward approaches an air-drawing tube 18, the particles of air attracted by said tube removing therewith the are into the tube and raising so its resistance. It may be mentioned that this artificial means for increasing the resistance of the are during the burning period in some cases must be effected from reasons resulting from the position of the carbons. If the carbons converging so the enlargement of the distance between the carbons WhiCil takes place with burning of the same is not sufficient to alone increase the resistance, the means described before must be provided to carry out this operation.
What I claim, and desire to secure by Letters Patent, iu'
1. In an electric-arc lamp, the combination with a pair of electrodes, of arc-regulating mechanism, and means actuated by a portion of the current shunted or diverted from the are for setting the said regulating mechanism into operation.
2. In an electric-arc lamp,-the combination with a pair of downwardly-pointed parallel or converging electrodes, of feeding mechanism for the said electrodes, and means actuated by a portion of the current shunted or diverted from the are for setting the said feeding mechanism into operation.
HUGO BREMER.
