Handbook for the use of electricians in the operation and care of electrical machinery and apparatus of the U. S. seacoast defenses ..
A technical manual issued by the U.S. War Department in 1904 for army electricians maintaining generators, searchlights, and wiring in seacoast fortifications. Line engravings show machines in plan, section, and elevation with lettered call-outs and dotted hidden parts, plus schematic wiring runs — useful for hairline mechanical linework, labelled diagram layouts, and cutaway views of motors and carbon-arc lamps.
