Description

About this book

"Spar-torpedo instructions for the United States Navy" is a naval manual written in the late 19th century. It explains how to equip, handle, fire, and maintain spar-torpedoes from ships and boats, with emphasis on electrical firing gear, gun-cotton safety, and standardized Navy fittings. The opening of the manual defines the Class D spar-torpedo outfit and distinguishes service, exercise, and contact torpedoes, describing their cases, stuffing-boxes, circuit-closers, spars, fittings, and cabling. It then lays out step-by-step procedures for priming with dry gun-cotton, testing detonators, splicing and fuzing, shipping torpedoes on secondary spars, and conducting circuit tests and firings from ships and boats, including immersion and stand-off distances; it also covers converting a service torpedo to contact firing and outlines improvised powder torpedoes.
