ELECTRIC-ARC LAM P.
SPECIFICATION forming part of Letters ,Patent No. 690,105, dated December 31, 1901.
Application led April 25, 1901. Serial No. 57,490. (No model.)
BERG, a citizen of the UnitedStates, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Electric Arc Lamps, of which the following is a specification. f
My invention relates to electric-arc lamps of the type known in the art as series alternating lamps.
The object of my invention is to simplify the construction of lamps employed in' series alternating circuits and to provide a means to close the circuit within which the lamp is included around the lamp should the operating mechanism of the lamp for any cause fail to act, and thus break the circuitbetween the carbone of the lamp.
The accompanying drawings will serve to illustrate my invention, in which- Figure 1 is a front View.` Fig. 2 is a side View. Fig. 3 is a diagram illustrating the circuit connections in the lamp.
In the drawings, 10 indicates the supporting-cover forthe lamp; 11, the supportingtube for the bottom of the lamp, (not shown,) fixed at one end to the cover 10.
, Located within the tube l1 and freely movable therein is-the upper. carbon l2. Surrounding the tube 11 is a freely movable sleeve 13. Secured to the tube 1l is a bracket 14, having the two arms 14a 14h. Pivoted in the arm 14a is a lever 15, and secured on the left-hand side of this arm is a weight 16. Pivotally connected to the sameend of the lever 15 is the piston 17 of the dash-pot 1S, pivotally mounted upon an arm 19, projecting upward from the bottom plate 2O of the lamp.
21 is an adjusting-screw in the right-hand arm of the bracket 14.
lConnected to the right-hand end ofthe lever 15 `is the armature 22 of the shunt-magnets 23. Interposed between the armature 22 and the end of the lever 15 is a spring 24. Also pivoted in the right-hand end of the lever 15 is a bent rod 25, pivotally connected at its lower-end with the sleeve 13. Secured on opposite sides of the sleeve 13 are the links 26 of the clutch-27'. l
28 represents an impedance-coil located below the top plate 10 and connected at one end to the contact-plate 29 and at the other end to the outgoing conductor 30.
Mounted upon the upper part of the counterweight 16 is a spring-contact 3l.-
The'operation ofthe .lamp is as follows: When no current is passingthrough the lamp, the counterweight 16, acting through the clutch 27, separates the cai-bons. When a current is passed through a circuit carrying one or more of these lamps, its path is through the shunt-magnet 23, which, as shown in the diagram, is connected around the arc. The magnet 23 attracts its armature 22, which, acting through the clutch 27, allows the carbons to feed and be brought together, and thus shunt-circuit the magnet 23. The counterweight being at this moment unresisted by the pull of the shunt-magnet then strikes the arc, and the arc is maintained practically constant by the varying action of the shuntmagnet acting against the counterweight. Should the upper carbon stick for any reason and not be fed downward when the clutch acts, the resistance at the arc will be increased and more current sent through the shuntmagnet, which attracts its armature and lifts the counterweight until the spring-contact 31 on the counterweight 16 is brought in contact with the contact 29 on the end of the impedance-coil. This action, it will be seen by reference to the diagram, shunts the current around the lamp through the impedance-coil, which has a resistance equal to that of the arc, extinguishes the arc, and thus maintains the integrity of the circuit within which the other lamps in series are included.
Having thus described my invention, I
' claim- 1. In au electric-arc lamp, the combination with the actuating mechanism for the upper carbon, an impedance-coil, and mechanism operated by such actuating mechanism which will close and maintain closed a circuit around the lamp and through such impedance-coil when the resistance of the arc exceeds a predetermined amount.
2. In an electric-aro lamp, the combination with the actuating mechanism for the upper carbon, an impedance-coil provided with a core, and in a normally open circuit around the lamp, and mechanism operated by said ac- IOO yio
tuating mechanism which will close and maintain closed said circuit around the lamp through said impedance-coil When the resistance of the arc exceeds a predetermined amount.
3. In an electric-arc lamp, the combination of a magnet in circuit around the arc, a pivoted lever connected to the armature of said magnet atv one end and carrying a counter- Weight at the other end, a clutch mechanism actuated by said lever, an impedance-coil provided With a core and in a normally open circuit around the lamp, a Contact device carried by the lever, and a contact device connected to the impedance-coil.
4. In an electric-arc lamp, the combination of asupporting-tube for the lamp mechanism, a shunt-magnet, a bracket secured to said tube, a lever pivoted in said bracket connected at one end to the armature of said magnet and carrying a Weight upon the opposite end, a contact device mounted on said Weight, an
impedance-coil provided with a core and in a normally open circuit around the lamp, and a contact device mounted on said impedancecoil and adapted to coact with the contact mounted upon said Weight.
5. In an electric-arc lamp, the combination of a supporting-tube, a bracket mounted on said tube7 a lever pivoted in said bracket, a Weight mounted on one end of the lever, a shunt-magnet, an armature for said shuntmagnet, a spring interposed between the end of said armature and one end of said lever, a sleeve movable upon said supporting-tube, a rod between said sleeve and said lever, and a clutch mechanism connected to said sleeve.
In testimony whereof I affix my signature in the presence of two Witnesses.
