Historic Steam Tricycle Engineering Diagram - Early Automotive Innovation #96257 (License: Personal Use)

This black-and-white engineering diagram depicts a three-wheeled steam vehicle from the late 19th century, featuring a tall vertical boiler with firebox, a large tubular condenser beneath it, and a compact engine mounted mid-frame. The power is transmitted via belts and gears to the rear wheel, while the front wheel serves as the steering unit; a fuel tank and water reservoir are integrated near the seat. Fine linework reveals valves, piping, and control levers typical of early mobile steam applications.

Used in historical transportation articles, museum exhibits, or engineering education pages to illustrate pre-automotive propulsion systems; matches user intent for researching vintage vehicles, steam technology, or industrial design evolution.
