content: Several prominent inventors of adding machines had associations with St. Louis.Two of them were patent attorney Halcolm Ellis and mechanical engineer Nathan W. Perkins Jr. In 1902 they took out a patent for an adding machine. Although this machine apparently was never produced, Ellis then patented a combination adding machine and typewriter, and tried to manufacture it in Massachusetts. When his funds dried up, Eillis returned to St. Louis and organized the Ellis Adding-Typewriter Company. The firm soon moved to New Jersey, with Perkins managing the engineering division of the company. By 1911 a modified, electrically powered Ellis adding typewriter was tried at four banks
