Engineering:Bird-cage lantern
From HandWiki
The original Ned Point Light in Massachusetts , showing its original bird-cage lantern.
A bird-cage lantern was the style of lantern common to United States lighthouses in the early years of the nineteenth century. The lanterns received their name because of their appearance; they are shaped like wire bird cages.
When Fresnel lenses were introduced to the country in the 1850s, most lighthouses were retrofitted with new lanterns, as the older ones could not support the new style of lens. Consequently, only four lighthouses with original bird-cage lanterns survive in the United States; those that do were discontinued before they could be fitted for the new lantern.
