The practical metal-worker's assistant : comprising metallurgic chemistry, the arts of working all metals and alloys, forging of iron and steel, hardening and tempering, melting and mixing, casting and founding, works in sheet metal, the processes dependent on the ductility of the metals, soldering, and the most improved processes, and tools employed by metal-workers, with the application of the art of electro-metallurgy to manufacturing processes, collected from original sources, and from the works of Holtzapffel, Bergeron, Leupold, Plumier, Napier, Scoffern, Clay, Fairbairn, and others
A 1872 Philadelphia metalworking manual by Oliver Byrne, published by H.C. Baird and drawing on sources such as Holtzapffel and Fairbairn, covering metallurgy, forging, casting and soldering for working metal-workers. The pictures are precise line diagrams of tools, machine parts and mechanisms in section and elevation, showing how each piece fits and moves, which suits designers wanting technical drawing vocabulary and clean mechanical schematics.
