JOSEF HENRIK HALLBERG, OF NEWV YORK, N. Y., ASSIGNOR TO GENERAL INCANDESCENT ARC LIGHT COMPANY, OF NEW YORK, A CORPORA- TION.

REGULATOR FOIR ALTERNATING SERIES ARC-LIGHT SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 766,824, dated August 9, 1904. Application filed January 29, 1902. Serial No. 91,733. (No model.)

To all whom it may concern.-

Be it known that I, J osnn HENRIK HALL- BERG, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Regulators for Alternating Series Arc-Light Systems, of which the following is a specification.

My invention relates to a device adapted to be connected in series with the generator and arc-lamps of an alternating series arc-light system, and which has for its purpose to maintain the current on the line constant irrespective of the number of lamps in operation.

A further object of my invention is to simplify the construction and decrease the cost of such transformer.

The accompanying diagrammatic drawings will serve to illustrate my invention.

Figure 1 is a vertical section through the inclosing case of a regulator, showing the movable core of the device supported upon a buoyant device which is immersed in a body of oil. Fig. 2 is a similar view showing the core suspended from a buoyant device.

In the drawings, 5 represents a suitable inclosing case with a removable cover 6. The interior of the case is adapted to be partially filled Witha body of oil 7 or other insulating fluid. In the construction shown in Fig. 1 a smaller body of oil is required than that shown in Fig. 2. Located within the case and suitably supported therein in any convenient manner are a pair of solenoidal magnets 8. Arranged'to have a vertical motion in such magnets is a core 9.

10 represents a float connected to the core 9 through the rod 11. In Fig. 1 the float is shown as attached to the bottom of the rod and in Fig. 2 near to the top of the rod. Secured to the top of the rod are the removable weights 12.

13 represents a disk of wood or other material, connected in Fig. l to the bottom of the float 10 and in Fig. 2 to the bottom of the core 9. The disk in Fig. 2 is provided with reliefvalves 14 15. Located under the disk 13, Fig.

2, is a spring 16, which has for its purpose to cushion the downward movement of the core 9.

17 represents weights which may be attached to the floats 10 for the purpose of decreasing the buoyancy of the floats; 18, lamps in the lamp-circuit.

The operation of the device is as follows:

When the resistance of the lamp-circuit is.

altered by cutting a lamp or lamps into or out of circuit, as the case may be, the attractive power of the solenoids 8 is altered. In the first instance when a lamp (or lamps) is cut in the power of the solenoids is decreased. In the second instance when a lamp (or lamps) is cut out the power of the solenoids is increased, with the effect of removing from or introducing into the lamp-circuit an impedance corresponding to the resistance of the lamps cut in or out. The position of the core 9 relative to the solenoids 8 may be regulated by adjusting the weights l2 and 17 to compensate for any variation in current strength in the lamp-circuit.

I do not limit myself to any special form of solenoid, core, or buoyant device for carrying and balancing the weight of the core, as many changes may be made in such parts without affecting the intent of my invention.

Having thus described my invention, I claim- 1. In a regulator for alternating series arclight systems, the combination of an inclosing case, a body of oil, a solenoidal magnet, located within the case, a movable core for said magnet, and a buoyant device floating in said body of oil and adapted to support and overcome the normal weight of said core.

2. In a regulator for alternating series arclight systems, the combination of an inclosing case. a body of oil, a solenoidal magnet located within the case, a movable core for said magnet, a buoyant device floating in said body of oil, and adapted to support and overcome the normal weight of the core, and means for adjusting the displacement of the float.

3. In a system of electrical distribution, a regulating reactance-coil having a moving part adapted to increase the choking efiect in the said float being so shaped as to displace increasing amounts of liquid per unit of immersion in the same proportion as the magnetic pull of the reactance-co1l decreases.

In testimony whereof I afiiX my signature in p the presence of two Witnesses.
