Franklin Day Jones

Franklin Day Jones (1879–1967) was an American engineering writer and editor closely associated with Machinery’s Handbook, the long-running industrial reference first published in 1914. Reliable catalog and author records identify him as one of the key editors of the handbook alongside Erik Oberg, and his name appears on many later editions as well.

He also wrote and contributed to books on machine-shop practice, toolmaking, and related workshop subjects. His published work points to a clear specialty: explaining mechanical and manufacturing knowledge in a direct, useful way for people who needed dependable guidance in everyday industrial work.
