Invention and Engineering
Aveling and Porter was a British agricultural engine and steamroller (road roller) manufacturer. Thomas Aveling and Richard Thomas Porter entered into partnership in 1862, and developed a steam engine three years later in 1865. By the early 1900s, the company had become the largest manufacturer of steamrollers (road rollers) in the world. The company used a rearing horse as its logo (based on the traditional white horse symbol of Kent), along with the motto Invicta (meaning "unconquered"; the traditional motto of Kent).
