Colonial laws in America required each house to have a bucket of water on the front stoop (especially at night) in case of fire, for the initial "bucket brigade" that would throw the water at fires. Philadelphia obtained a hand-pumped fire engine in 1719, years after Boston's 1654 model appeared there, made by Joseph Jencks, but before New York's two engines arrived from London.
By 1730, Newham, in London, had made successful fire engines; the first used in New York City (in 1731) were of his make (six years before formation of the NYC volunteer fire department). The amount of manpower and skill necessary for firefighting prompted the institution of an organized fire company by Benjamin Franklin in 1737. Thomas Lote built the first fire engine made in America in 1743.
Ericsson made a similar one in New York in 1840. John Ericsson is credited with building the first American steam-powered fire engine.
Until the mid-19th Century most fire engines were maneuvered by men, but the introduction of horse-drawn fire engines considerably improved the response time to incidents. The first self-propelled steam engine was built in New York in 1841. It was the target of sabotage by firefighters and its use was discontinued, and motorized fire engines did not become commonplace until the early 20th Century.
For many years firefighters sat on the sides of the fire engines, or even stood on the rear of the vehicles, exposed to the elements. While this arrangement enhanced response time, it proved to be both uncomfortable and dangerous (some firefighters were thrown to their deaths when their fire engines made sharp turns on the road), and today nearly all fire engines have fully enclosed seatings for their crews.
Early pumpers
1920 Kissell Ladder Wagon. The Kissell Motor Car Company of Hartford, Wisconsin, was famous for its sporty cars, especially the Gold Bug. Kissell also made trucks. They built this long base chassis for their home town in 1920. The Hartford FD then placed the body from a horse drawn Seagrave ladder wagon atop the chassis and voila! they had a city service ladder truck. They kept this truck in service until about 1965.
1935 American La France Model 400 fire engine from Norfolk, Nebraska. It has a 1,250 gpm rotary pump and the famous American La France V-12 engine.
