ELECTRIC ARC LAMP.

UNITED STATES" PATENT OFFICE.
BENJAMIN ADAIR AND CHARLES KLEWER, OF DENVER, COLORADO.
ELECTRIC-ARC LAMP.
SPECIFICATION forming part of Letters Patent No. 508,392, dated November '7, 1893.
Application filed March 6, 1893. Serial No. 464,923. (No model.)
have invented certain new and useful Improvementsin Out-Outs forBrush Arc Lamps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
Our invention relates to improvements in cut outs for Brush arc lamps and the same consists of the features, arrangements and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings in which is illustrated an embodiment thereof.
In the drawings, Figure 1 is a front view of the lamp provided with our improved cut out. Fig. 2 is a side View of the same. Fig. 3 is a diagrammatic View illustrating the circuits.
Similar reference characters indicate corresponding parts or elements of the mechanism in the several views.
Let the numeral 5 designate the framework-of the lamp, 7, and 8 the wires of the main circuit, 9 a small magnet having its coils in the shunt circuit and 10 another magnet having its coils in the main circuit of the lamp. v 7
From wire 7 abranch wire 12 leads to one extremity of the main coil of one solenoid, while another wire 13 leads to one extremity of the corresponding coil of the other solenoid. From the opposite extremities of these main solenoid coils lead. wires 14 and 15 which unite at 16, thus forming a connection between these solenoid coils. From this connection 16 leads a wire 17 to one extremity of the coils of magnet 10, while from the opposite extremity of said coils leads a wire 22 to the lamp frame. From a contact 18 supported upon the frame of the last named magnet, but insulated therefrom,leads a wire 19 to one extremity of the resistance coils 20, while from the opposite extremity of this coil leads awire 21 to the other wire 8 of the main circuit. From wire 7 leads a branch wire 23 to one extremity of the shunt coils of the solenoids, while from the opposite extremity of these coils leads a wire 24 to the one extremity of the coils of the magnet 9, while from the opposite extremity of this magnet, leads a wire 25 to the conductor 8 of the main circuit. From conductor '7- leads a branch wire 26 to the armature 27 of magnet 9, while from a contact 29 attached to the magnet frame, leads a conductor 28 to wire 8 of the circuit. From conductor7leads a wire 30 to the armature 31 of magnet 10. This armature is supported on the lamp frame but insulated therefrom. When the magnet is not energized the armature is drawn away from the core by a coil spring 32 attached to the armature atone extremity and to the lamp frame at the opposite extremity. This spring is insulated from the frame.
Assuming that thelamp is burning and the electrodes are separated by the proper arc the magnet 10 is energized and the armature 31 held in contact with its core. In this case the coils of magnet 9 do not carry enough current to draw the armature 27 to contact 29. Hence both short circuit connections are broken. When, however, as the electrodes are consumed and the resistance of the arc increases sufficiently, the current begins to flow through the thin coils of the solenoids and the coils of magnet 9, and when the current is of sufficient strength the armature 27 will be drawn to engagement with contact 29, and the current momentarily short circuited between conductors 7 and 8, through the medium of wire 26, armature 27, contact 29 and wire 28, thus cutting the current for an instant .out of the lamp, allowing the armature 31 to drop to contact 18, thus establishing the permanent short circuit from wire 7 through conductor 30, armature 31, contact 18, wire 19, resistance coil 20 and 21 to condoctor 8 of the main circuit. When however, the electrodes are renewed and it is desired to re-establish the main circuit of the lamp, the resistance of the coil 20 is such that the current will be driven through the main coils of the solenoids and the coils of magnet 10 which being energized draws the armature 31 away from contact 18 and breaks the short circuit automatically.
Having thus described ourinvention, what we claim is- 1. The combination with the Brush arclamp of a magnet having its coils interposed in the shunt circuit, a short circuit connection through the armature of this magnet when the latter is sufliciently energized, another magnet the coils of which are in the main lamp circuit, and a short connection through the armature of this magnet when not energized, substantially as described.
2. The combination with the Brush arc lamp of a magnet having its coils interposed in the shunt circuit of the lamp, a momentary short circuit connection through the armature of the magnet when energized, another magnet the coils of which are in the main lamp circuit and a permanent short circuit connection through the armature of the last named magnet when not energized, a resistance coil being interposed in the last named circuit, substantially as described.
In testimony whereof we atfix our signatures in presence of two Witnesses.

It is hereb y certified that Letters Patent No. 508,392 granted November 7, 1893, upon the application ofhBenjamin Adair and Charles Hr Klewer, of Denver, Colorado, for an improvement in Electric-Are Lamps, were erroneously issued to said Adair and Klewer, as owners of the invention; that said Letters Patent should have been issued to said Benjamin Adair and Charles H. Klewer and Charles Robson, jointly,
said Robson being owner of a part interest, as shown by the record of assignments in this office 5 and that said Letters Patent should be read with this correction therein that the same may conform to the record of the ease in the Patent Office.
