Thomas Green & Son has a rich history that spans over a century. The company was founded by Thomas Green in 1835.

One of the earliest milestones in the company's history is the establishment of the Smithfield Ironworks in 1848. This marked a significant turning point for Thomas Green, as it provided him with a site to build and manufacture his products.

Thomas Green started building lawn mowers in 1855, and his innovative designs quickly gained recognition. In 1858, a Greens mower won the first prize in the 1st lawn mower trials at London Horticultural Gardens at Chiswick.

The Silens Messor, patented in 1860, was a significant improvement in lawn mower design, featuring a chain drive that made the machine lighter. This design became the backbone of Thomas Green's business until production ended in 1935.

The company was incorporated as a Limited Company in 1862 and later became a private company in 1879. During this period, Greens started building locomotives in the 1880s, with 157 tram locomotives built between 1885-98.

Greens also opened a London works at New Surrey Works, Southwark, London in the 1890s, where they manufactured various products, including Vertical, Cornish, and Lancashire boilers.

Thomas Green's tram engines were well-known for their innovative designs and ability to meet the stringent regulations of the time. They started building tramway locomotives in 1885.

The Red Flag Act of 1861 and 1865 effectively prohibited the use of steam tramways in Britain, but the Highways and Locomotives (Amendment) Act 1878 set out a more workable arrangement. This included rules for engine speed, emissions, noise, and visibility.

Engineers at Thomas Green developed their own design using a horizontal boiler, inclined cylinders, and Joy valve gear. This design quickly became a market leader.

Some of the key features of Thomas Green's tram engines included a speed governor, which prevented speeds in excess of 10 miles per hour. The exhaust was designed to pass through a chamber in the firebox to provide reheat, making the steam invisible.

The construction process involved assembling the engine boiler, motion, and wheels on the ground floor, and then lowering the body of mild steel-plate onto the frames. This was a remarkable feat that required brute force and cuss words to complete.

Here are the key regulations that Thomas Green's tram engines had to meet:

Preservation involves understanding the scope and content of historical projects, like the alterations to Thomas Green & Son Limited's showroom and offices.

The proposal for these alterations aimed to provide maximum flexibility for product display, achieved through movable screens, stands, canopies, and adjustable spotlights.

A new reception room and office were part of the project, along with renovations to existing offices.

The file contains design development drawings and textual records, providing valuable insights into the project's development.

When preserving materials, it's essential to maintain their original order to ensure their integrity is preserved. Materials in this series were kept in the original order in which they were received.

Maintaining the original order helps to prevent any damage or disorganization that could occur if the materials were rearranged.

Thomas Green & Son produced a range of steam road vehicles, including fairground centre-engines, road tractors, and agricultural tractors.

One of their most well-known products was the steamroller, which started in 1872 with a vertical boilered model for the Royal Gardens, Windsor.

They introduced a convertible model in 1880, which was a traction engine or road roller, and a conventional horizontal boilered model followed in 1881.

Their range of steamrollers enabled them to become one of the market leaders, with around 300 machines supplied.

Thomas Green & Son also produced petrol engined rollers, starting with the first one in 1905, and later diesel engined models, such as the DRM model in the 1930s.
