He was commissioned as an ensign in the U.S. Navy. During his ensuing naval service, he first served on the USS Richmond, then the USS Minnesota. While his ship was in Newport, Rhode Island, in 1881, Sprague invented the inverted type of dynamo. After he was transferred to the USS Lancaster, flagship of the European Squadron, he installed the first electric call-bell system on a U.S. Navy ship. Sprague took leave to attend the Paris Electrical Exhibition in 1881 and the Crystal Palace Exhibition in Sydenham, England in 1882, where he was on the jury of awards for gas engines, dynamos and lamps.
