HistoryEdit

Thornycroft started out with steam vans and lorries. John Isaac Thornycroft, the naval engineer, built his first steam lorry in 1896. This was a 1-ton steam Van, that looks like a cross between a rail guards van and a closed horse drawn wagon. Their first petrol vehicle was in 1902 and the company completed the move into internal combustion engine power in 1907. (In Germany, Daimler build a production Gasoline engined truck in 1896). [1]

The company built cars for a short period of time after the move to Basingstoke and claimed to rival Rolls Royce for build quality. A number of examples are in the Milestones Museum in Basingstoke. Thornycroft built their own engines and all the other components used in there vehicles. Thereafter, the vehicle building firm and the marine side (later to become Vosper Thornycroft) were separate companies.

From 1931, Thornycroft used names for their vehicle range - often descriptive and colourful ones.

In 1946 as part of a plan to diversify following the end of War Works (building 20,000 trucks) they started to develop a Combine Harvester, and built a prototype in 1948. The design was by Eli Beavor, a local Agricultural engineer, rather than the firm's own designers. The machine had a 7 ft cut and a drum of virtual the same size. The machine was built from a lot of truck parts and had several design quirks as a result. They used a Thornycroft ER4 4-cylinder petrol engine of 65 hp (48 kW) mated to a 4 speed gear box and a truck axle, with the drum over the top thus making servicing a problem as well as being top heavy. They built approximately 6 prototypes before dropping the project. The machines were marketed as the "Beavercroft" combine in 1949, but then vanished.[2]

In 1948, the company name was changed to Transport Equipment (Thornycroft) Ltd to prevent confusion with the shipbuilding Thornycroft company. During the 1960s to the 1970s, the hit British sit com Dad's Army, a Thornycroft van was used as Jones the butcher's van.

They were taken over by Associated Equipment Company (AEC), by then Associated Commercial Vehicles Ltd and production was limited to the Nubians, Big Bens and Antars. ACV was then taken over by Leyland who already had a specialist vehicle unit in Scammell, another manufacturer of large haulage vehicles. Thornycroft's Basingstoke factory was closed in 1969 and specialist vehicles transferred to Scammell at Watford.

Today, the Thornycroft name is used by a builder of marine diesel engines for private and light commercial use- the engines being based around small-capacity engines designed by Mitsubishi. Despite Thornycroft being effectively closed down by Leyland, the operation's parent company is now the main provider of spare parts for Leyland-built marine diesels, which for many years were highly popular for use in canal barges and narrowboats (now a market making increasing use of the modern-day Thornycroft engines). 

MAY 2018 UPDATES 

John Isaac Thornycroft, the naval engineer, also formed the Thornycroft Steam Carriage and Van Company which built its first steam van in 1896. This was exhibited at The Great Exhibition, and could carry a load of 1 ton. It was fitted with a Thornycroft marine launch-type boiler (Thornycroft announced a new boiler designed for their steam carriages in October 1897[1]). The engine was a twin-cylinder compound engine arranged so that high-pressure steam could be admitted to the low-pressure cylinder to give extra power for hill-climbing.[2] A modified version of the steam wagon with a 6-cubic-yard tipper body was developed for Chiswick council in 1896 and went into service as a very early self-propelled dust-cart. While the original 1896 wagon had front-wheel drive with rear-wheel steering, the tipper dust-cart had rear-wheel drive and front-wheel steering. The Thornycroft tipper was built by the Bristol Wagon and Carriage Company, though engined by Thornycroft.[3]

Thornycroft's first petrol vehicle was built in 1902,[4] and the company completed the move into internal combustion engine power in 1907. Thereafter the vehicle building firm and the marine side (later to become Vosper Thornycroft) were separate companies.[5]

From 1931, Thornycroft used names for their vehicle range – descriptive and colourful ones. During World War II the company designed the Terrapin[6] and other war-related vehicles.

In 1948, the company name was changed to Transport Equipment (Thornycroft) Ltd to prevent confusion with the shipbuilding Thornycroft company. The company was well known for providing fire-engine chassis, with multi-axle drive for uses such as airports. A limited number of 4x4 chassis were also provided to Worcester-based fire engine manufacturer, Carmichael for sale to civilian brigades in the 1950s.[citation needed]

They were taken over in 1961 by AEC parent Associated Commercial Vehicles Ltd,[7][8] and production was limited to Nubians, Big Bens and Antars, although the Thornycroft-designed six-speed constant mesh gearbox was used in AEC and later medium weight Leyland and Albion trucks. ACV was then taken over by Leyland in 1962. They already had a specialist vehicle unit in Scammell, another manufacturer of large haulage vehicles. Thornycroft's Basingstoke factory was closed in 1969[9] and specialist vehicles transferred to Scammell at Watford
