The practical gas engineer; a manual of practical gas and gasoline knowledge
A technical manual on gas and gasoline engines written by E. W. Longanecker and published around 1901 in Chicago for mechanics, operators and engine owners. Halftone photographs show stationary engines with heavy spoked flywheels, magnetos and igniters, alongside line diagrams of piping, belt drives and exhaust runs — usable as machine silhouettes, gear detail and schematic linework.
