[Engraving: 60-Inch Projector: original size (9K) | 9x enlarged (68K)]
The Searchlight Department employs about 125 men and about 200 large searchlights are annually manufactured here. The building has a tower with trackage and switchboard for practically testing its product. Projectors of General Electric Company make have come rapidly into use by the Government for coast defense and upon warships, and upon merchant ships as well. The largest projector ever built in the United States was made at Schcnectady for use at the St. Louis Exposition. This projector is 80" in diameter, and has a positive carbon 2-1/4" in diameter. It consumes nearly 17 Kw. at the arc.
In addition to searchlights from 9" in diameter up, controlled by hand or from a distance by electric motors operated through a cable, steam turbine operated locomotive headlights, and complete portable searchlight outfits, this department manufactures a keyboard manipulated "Night Signal System" in use by the United States Government, a telltale board for the control of running lights on board ship, and similar apparatus.
