Synopsis
Locomotive Engine: Including A Description Of Its Structure, Rules For Estimating Its Capabilities, And Practical Observations On Its Construction And Management by Zerah Colburn. This early American technical treatise surveys the principles of steam power and the locomotive, combining theoretical discussion with detailed practical guidance. It explains the properties of steam, the relationship between pressure, volume, and temperature, and the concept of latent heat, before outlining the threefold structure of a locomotive: the boiler for steam generation, the engine itself for applying steam to motion, and the wheels for traction. The work then provides in-depth descriptions of boiler construction, steam chests and valves, cylinders, frames, wheels, pistons, and pumps, with numerous patterns from different builders and discussions of draught, exhaust, and expansion. It also offers sections on engine management, maintenance, and cost, and includes tables, calculations, and demonstrations of how to estimate power, fuel use, and performance. The book is a foundational text in 19th?century locomotive engineering and systematizes practical knowledge for designers and operators alike.
