S. BERGMANN.
AUTOMATIC ELECTRIC SWITCH. No. 461,791. Patentefi 001;. 20, 1891.
Kay A UNITED STATES SIGMUND BERGMANN, on NEW YORK,
PATENT OFFICE.
N. Y., ASSIGNOR TO THE BERGlllANN MANUFACTURING COMPANY, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 461,791, dated October 20, 1891.
Application filed February 2 5 1891. Serial No. 382,693. (No model.)
To all whom it may concern.-
Be it known that I, SIGMUND BERGMANN, of New York, in the county and State of New York, have invented a certain new and useful 5 Improvement in Automatic Switches, of which the following is a specification.
I will describe an apparatus embodying my improvement, and then point out the novel features in a claim.
In the accompanying drawings, Figure 1 is a diagram of an apparatus embodying my improvement. Fig. 2 is an enlarged frontview of an automatic switch included in said apparatus, the front of its box being removed.
Similar letters and figures of reference designate corresponding parts in all the figures.
A designates a dynamo-electric machine of any desired form. A wire 1 leads from one of the brushes of the dynamo and terminates 2 in a metal contact-piece 2. Adjacent to the contact-piece 2 is a similar contact-piece From the contact-piece 3 a wire 4 extends. A wire 5 extends near the wire 4, and a number of electric lamps 6 are shown as con- 2 5 nected in multiple arc with these wires 4 and 5. The wire 5 at one end terminates in a contact-piece 7, which may be like the contactpieces of the style mentioned. A contactpiece Sis arranged adjacent to the contactpiece 7. The contact-pieces 2 and 3 may be electrically connected and the contact-pieces 7 and 8 electrically connected by means of a switch 13, here shown as consisting of a lever carrying the armature c of an electro-magnet C and provided with contact-pieces 1) b The electro-magnet O attracts its armature c in a direction to cause the contact-piece b to impinge upon the contact-pieces 2 and 3, so as to establish electrical communication between them and the contact piece b to impinge upon the contact-pieces '7 and 8 to establish electrical communication between the latter. Of course the contact-pieces b b must be insulated from each other. lVhen the magnet 0 is de-energized a spring 0 retracts the lever B, so as to move its contact-piece b away from the contact-pieces 2 3 and its contact-piece 19 away from the contact-pieces '7 and 8. From the contact-piece S a wire 9 extends to one end of the coils of an electromagnet D. The other end of the coils of this electro-magnet is connected to a wire 10, which extends to the other brush of the dynamo from that with which the wire 1 communicates. Obviously, whenever the electro-magnet 0 attracts its armature a circuit will be established from the dynamo through the wire 1 to the contact-piece 2, along the latter to the contact-piece Z), from this contact-piece to the contact-piece 3, from the latter along the wire 4. thence through the electric lamps 6, from the latter along the wire 5, contact piece 7, contact-piece b contact-piece 8, to the wire 9, thence to the coils of the electromagnet D, and, finally, along the wire 10 to the dynamo.
The electro-magnet O is in a shunt which, as here represented, is formed of a wire 11, extending from the wire 1 to a resistance device or electric lamp 12, a wire 13, extending from the resistance device or lamp 12 to one end of the coils of the electro-magnet C, a wire 1+1, extending from the other end of the coils of the electro-magnet C to a contactpiece 15, a metallic switch-lever (Z, and a wire 16, leading from the switch-lever to the wire 10. The switch-lever (Z carries an armature d, which coacts with the electro-magnet D, and has combined with it a weight (Z or equivalent device for normally holding said lever against the contact-piece 15. Solong as the lever d impinges against the contact-piece 15 the electro-magnet C will remain in circuit, and the lever B will, through its contactpieces 1) b establish electrical communication between the pair of contact-pieces 2 3 and the pair of contact-pieces 7 8.
At any time that the current exceeds the desired limitsas, for instance, by varying the number of lamps in the circuit beyond the limits contemplated for the circuit-the electro-magnet D will become powerful enough to draw the lever (Z away from the contactpiece 15. Immediately that this occurs the electro-magnet C will be cut out of electric 5 circuit, and the main circuit will be disrupted by the retraction of the armature B, ensu- 1ng' upon the cutting out of the electro-niagnet 0.
Obviously the electro-inag'net D and its appurtenances form a cut-out.
WVhat I claim as my invention, and desire to secure by Letters Patent, is
The combination, with an electric circuit, of a switch, a shunt-circuit serving to close said switch, an electro-magnet in series in the main circuit and serving to open the said
