George Selden's 1895 Patent for a Road Engine

George Selden's 1895 patent describes a 'road engine,' a precursor to the automobile, focusing on a combined engine and vehicle design.

What it covers

This patent, granted in 1895, outlines a 'road engine' which integrates a motive engine with a vehicle chassis. The design focuses on the overall structure of a self-propelled carriage. It details components like the engine, its connection to the wheels, and steering mechanisms, aiming to create a functional automobile.

What it doesn't cover

• —Does not cover modern internal combustion engines with specific fuel injection systems.
• —Does not cover electric vehicles or hybrid powertrains.
• —Does not cover specific safety features like airbags or anti-lock brakes.
• —Does not cover advanced navigation or infotainment systems.
• —Does not cover specific materials used in modern vehicle construction.

The clever bit

The novelty lay in combining the engine and vehicle into a single, patentable concept, rather than just patenting the engine itself. It aimed to cover the entire self-propelled carriage.

Why it matters

This patent is historically significant as one of the earliest attempts to patent the concept of a complete automobile. George Selden's patent became a focal point in early automotive patent disputes, particularly involving Henry Ford.
