No. 264,662. Patented Sept. 19, 1882. United States Patent Office. THOMAS A. EDISON, OF MENLO PARK, NEW FOR DYNAMO-ELECTRIC MACHINES. SPECIFICATION forming part of Letters Patent No. 264,662, dated September 19, 1882. Application filed August 7, 1883. (No model.) To all whom it may concern: Be it known that I, Thomas A. Edison, ofMenlo Park, in the county of Middlesex and > State of New Jersey, have invented a new and5 useful Improvement in the Regulation of Dy- ► namoor Magneto Electric Machines, (Case ;) and I do hereby declare that the follow-ing is a full and exact description of the same,reference beinghad to the aceompauyiugdraw- ■io ing, and to the letters of reference markedthereon. t The object of my invention is to producesimple and efficient means for regulating thegeneration of current by a dynamo or mag-fig neto electric machine supplying a multiple-arc■ system of electrical distribution, according
