Having thus described my invention, I claim 1. A regulator for alternating series arelight systems, comprising a device responsive to any increase of current upon the line within predetermined limits, and which will act when energized to introduce an impedance upon the line proportional to any decrease in load upon such line, and means for automatically hanging the ratio of the current transformation through said device, whereby the power factorof the system will be maintained practically constant from zero to full load.

2. A regulator for alternating series arelight systems, comprising a device reponsive to any increase of current upon the line within predetermined limits, and which when energized will introduce an impedance upon the line proportional to any decrease in load upon such line, a transforming device introduced between said first-named device and the main source of energy, and means actuated by said first-named device which will change the ratio of current.- transformation through the transformer in proportion to the decrease in load in the translation-circuit which the first-named device is designed to regulate.

3. A regulator for alternating series arelight systems, comprising a case containing a body of oil, a pair of solenoids having a fixed position in such case, a core for saidsolenoids, a buoyant device for overcoming the weight of the core, means for regulating the positionof the core in the solenoids, a current-transforming device, and means actuated by the core for determining the active portion of said transforming device.

4:. A regulator for alternating series arclight systems, comprising a case containing a body of oil, a pair of solenoids having a fixed position in such case, a device'buoyant in said body of oil, a core for said solenoids carried by said buoyant device, a transformer having its secondary coil divided into sections, and means carried by said core for progressively cutting said transformer-sections out of circuit.

5. A regulator for alternating series arclight systems, comprising a pair of coacting elements, one element fixed and the other movable, a transformer having its secondary divided into a series of sections, and means energized by the movement of the movable element for progressively changing the ratio of transformation from the transformer tothe fixed element.

In testimony whereof I affix my signature in the presence of two witnesses.
