All I could find is about the Delco Company " The name Delco came from the Dayton Engineering Laboratories Co., founded in Dayton, Ohio, by Charles Kettering and Edward A. Deeds in 1909. Delco was responsible for several innovations in automobile electric systems, including the first reliable battery ignition system and the first practical automobile self-starter.
Initially Kettering and Deeds were co-workers at National Cash Register Company (NCR). Kettering and Deeds had a lifelong professional relationship and friendship. In 1904, Deeds hired Kettering at NCR to motorize the cash register.
