Ruston & Hornsby was an industrial equipment manufacturer in Lincoln, England founded in 1918. The company is best known as a manufacturer of narrow and standard gauge diesel locomotives and also of steam shovels. Other products included cars, steam locomotives and a range of internal combustion engines, and later gas turbines. It is now a subsidiary of Siemens, its Diesel business went to MAN Energy Solutions that in 2025 still provides support for Ruston-engines.[1]

Key Information

Background

Proctor & Burton was established in 1840, operating as millwrights and engineers. It became Ruston, Proctor and Company in 1857 when Joseph Ruston joined them, acquiring limited liability status in 1899. From 1866 it built a number of four and six-coupled tank locomotives, one of which was sent to the Paris Exhibition in 1867. In 1868 it built five 0-6-0 tank engines for the Great Eastern Railway to the design of Samuel Waite Johnson. Three of these were converted to crane tanks, two of which lasted until 1952, aged eighty-four. Among the company's output were sixteen for Argentina and some for T. A. Walker, the contractor building the Manchester Ship Canal.

During the First World War, Ruston assisted in the war effort, producing some of the first tanks and a number of aircraft, notably the Sopwith Camel.

On 11 September 1918, Ruston, Proctor and Company merged with Richard Hornsby & Sons of Grantham to become Ruston and Hornsby Ltd (R&H). Hornsby was the world leader in heavy oil engines, having been building them since 1891, a full eight years before Rudolph Diesel's engine was produced commercially.

Ruston built oil and diesel engines in sizes from a few HP up to large industrial engines. Several R&H engines are on display at the Anson Engine Museum at Poynton, Manchester and also at Internal Fire - Museum of Power, Tanygroes near Cardigan.[2] The company also diversified into the manufacture of petrol engines, again from around 1.5 hp upwards, some of these designs were later manufactured under licence by The Wolseley Sheep Shearing Machine Company.

Steam machinery

This ran the irrigation pump to draw water from the Murray River for the Coomealla Irrigation Area. It is now an exhibit in a park in the town.

The firm were builders of steam engines and portable steam engines for many years, mainly for the agricultural market; however, they also created steam rollers which were used for making roads and owned by contractors and councils.

First World War

[edit]

In the First World War, the company made around 2,750 aeroplanes and 3,000 aero engines. The 1,000th Sopwith Camel (B7380), built at the plant in 1917,[3][4] was named the Wings of Horus. The company built around 1,600 Sopwith Camels, 250 Sopwith 1½ Strutters, and 200 Royal Aircraft Factory B.E.2s. The company, as Ruston & Proctor, was the largest British builder of aero-engines in the war, and built the largest bomb of the war. One of the directors, Frederick Howard Livens, had a son who was an army officer on the front line. Captain William Howard Livens was sent to Lincoln, where he developed the Livens Projector and the Livens Large Gallery Flame Projector.

Neighbouring manufacturer Clayton & Shuttleworth also built planes.

In 1919, Colonel J.S. Ruston was inspired to create a garden suburb in Lincoln – the Swanpool Garden Suburb. His vision was to provide affordable houses for his workers, with easy access to healthy outdoor recreation, such as a pleasure ground, cricket ground and swimming baths. Ruston purchased 25 acres of the Boultham Hall estate and established the Swanpool Co-operative Society. Architects Hennell and James of London created the designs for the houses, which were built between April 1919 and September 1920. The vision for the new suburb included a technical institute, church and schools. After running into financial difficulties the development was sold in 1925 to Swanpool Garden Suburb Ltd, a private company, but only 113 of the planned 2–3000 houses had been constructed and no more were built.[5]

The Ruston-Hornsby car

[edit]

After the First World War the company attempted to diversify and one outcome was the Ruston-Hornsby car. Two versions were made, a 15.9 hp with a Dorman 2614 cc engine and a larger 20 hp model with 3308 cc engine of their own manufacture. The cars were, however, very heavy, being built on a 9-inch chassis[clarification needed], and extremely expensive – the cheapest was around £440 and the most expensive nearly £1,000, and within a few years other makers were selling similar vehicles that weighed only 3/4 ton and cost around £120–200 – and never reached the hoped-for production volumes. About 1,500 were made between 1919 and 1924, two of which are still retained by Siemens on the Lincoln site. One is fully restored in running/driving condition, while the second example is still awaiting attention.[6]

The R-H car was developed by the chief engineer, Edward Boughton, who joined the company in 1916 after helping to develop the tank. Later he would start the Automotive Products Group (APG) in Leamington Spa in 1920 which made Borg & Beck clutches, Lockheed hydraulic brakes, and Purolator fuel filters.

Second World War

[edit]

In September 1944, when the German Wehrmacht OB West headquarters at Saint-Germain-en-Laye (near Paris) were captured, previously commanded by Field Marshal Günther von Kluge (from 2 July 1944), they were found to be powered by Ruston diesel engines.

It built the first prototype of the Valiant tank in 1944. The Grantham site built the Matilda II tank.

Diesels and gas turbines

[edit]

Ruston & Hornsby was a major producer of small and medium diesel engines for land and marine applications. The company began to build diesel locomotives in 1931 (and continued up until 1967). It was a pioneer and major developer in the industrial application of small (up to 10,000 kW) heavy duty gas turbines from the 1950s onwards. In the 1960s it was Europe's leading supplier of land-based gas turbines. It introduced Dry Low Emission (DLE) combustion technology in the mid-1990s becoming market leaders.

The initiation of the production and design of gas turbines was largely due to Bob Feilden[7] CBE (1917–2004) who joined the company in 1946. Gas turbines were first produced in 1952.

The Beevor Foundry on Beevor Street was opened[8] in 1950 by General Sir William Joseph Slim (later Field Marshal William Slim, 1st Viscount Slim), and claimed to be the biggest foundry in Europe.

In the 1950s, it was producing one turbine a fortnight. The company sold its 1,000th gas turbine in July 1977. It won the MacRobert Award in December 1983 for the Tornado gas turbine. The company's Cambridge-educated Egyptian chairman, Dr Waheeb Rizk OBE, was concurrently President of the IMechE from 1984 to 1985 and also President of the International Council on Combustion Engines from 1973 to 1977. He was Managing Director from 1971 to 1983 and developed the W layout for gas turbine power stations that were used as emergency generating stations for the National Grid, also known as peaking power plants. These had to be developed due to prolonged electricity blackouts in south-east England in 1961 caused by cascading failure. It built the first gas turbine to burn North Sea gas, for the Eastern Gas Board in Watford. In 1981 it won an order to power the Urengoy–Pomary–Uzhgorod pipeline (Trans-Siberian Pipeline).

Research work was done in conjunction with the University of Sussex and with Cranfield University in the 1980s, where extensive development was undertaken of the combustion chamber and of the gallery to the turbine.

Gas turbine product range

[edit]

Industrial Gas Turbines of note manufactured at the Lincoln plant:

  • TA
  • TB
  • TD
  • Typhoon (SGT-100)
  • Tornado (SGT-200)
  • Tempest (SGT-300)
  • Cyclone (SGT-400)

Boilers

[edit]
Main article: Vertical boiler with horizontal fire-tubes

Until the late 1960s, it produced Thermax boilers. The boiler business was sold for £1.75m to Cochrane & Co of Annan, Dumfries and Galloway in October 1968, that was bought by John Thompson of Wolverhampton four months later. It was bought by Clarke Chapman in 1970.

Energy schemes

[edit]

In 1957, it was the first company to fit a main Royal Navy ship (HMS Cumberland) with a (experimental) gas turbine.

In 1959, it opened a new type of power plant using waste sewage gas that powered eight turbines at Britain's biggest sewage works at the Northern Outfall Sewer at Beckton in East London. This was an 18,000 horsepower combined heat and power plant.

The company pioneered combined heat and power schemes. The company began this technology in Cortemaggiore, Emilia-Romagna in 1956 at the Agip (Azienda Generale Italiana Petroli) oil refinery.[9] By the late 1960s, Ruston & Hornsby CHP units were installed in Australia, Germany, the US, South America, and the Middle East.

In the 1970s, these CHP schemes were not as well developed as today because electricity companies were not interested in developing a market that would provide direct competition to themselves. CHP schemes were then known as total energy schemes, which comprised exhaust heat recovery. The company won the Queen's Award for Enterprise: International Trade (Export) in 1977, 1978 and 1982.

The large Singer factory in Clydebank, which employed 11,000 people, was notably powered by Rustons turbines. The King Faisal Specialist Hospital was installed with a CHP unit in 1975. Whitehall[clarification needed] in London is heated and has its electricity from a CHP unit built in the late 1990s.

Ownership and acquisitions

[edit]

Paxman

[edit]

In 1940 R&H bought a controlling interest in the well-known Paxman diesel engine company of Colchester in Essex. In the later stages of the war, Paxman built 4,000 diesel engines that powered all the British-built tank landing craft (LCT) on D-Day. It supplied diesel engines for British Rail locomotives in the 1960s. From 1954 to 1964 the company's Managing Director was Geoffrey Bone[10] who had been part of the Power Jets team, and whose father Victor Bone was Managing Director of R&H from 1944 until his death. It was due to Geoffrey Bone that Bob Feilden was recruited for R&H who subsequently formed the gas turbine manufacturing operations.

In 1934 the company had formed Aveling-Barford from two companies Aveling & Porter of Kent and Barford & Perkins of Peterborough, using a former site of R&H.[11] The company closed its Grantham diesel-engine factory in 1963.

English Electric

[edit]

In November 1966, R&H was purchased by English Electric. Robert Inskip, 2nd Viscount Caldecote became Chairman of the company. Subsidiaries of R&H included Bergius-Kelvin of Glasgow, Davey, Paxman & Co of Colchester (now owned by MAN Energy Solutions) and Alfred Wiseman Gears in Grantham.

Up to that point, the company had been listed on the London Stock Exchange. This formed Britain's second largest diesel engine group, second to Hawker-Lister. From that moment on it was a subsidiary of a larger company. It became known as the Ruston Turbine Division of English Electric Diesels.

Following the acquisition by English Electric the production of large Ruston engines was moved to the English Electric Vulcan Foundry factory in Newton-le-Willows. The production of the smaller engine range was moved to Stafford where it became a part of the Dorman Diesel range. Turbine technology was concentrated in Lincoln with Napier turbochargers moving from Liverpool to Lincoln in 1967. In 1969 the Lincoln site became Ruston Gas Turbines. The name was then changed to European Gas Turbines in 1989 following the merger of GEC and Alcatel Alsthom. Later this business was sold to Siemens. The gas turbine business is still in the old Ruston factory in the centre of Lincoln.[12]

GEC and Alstom

[edit]

R&H was included in the purchase of English Electric by the General Electric Company (GEC) in 1968. By the end of 1969 the Lincoln subsidiary company was known as Ruston Gas Turbines.

The Ruston Paxman diesels division became known as Ruston Diesels, and moved to the former English Electric diesel works. The former Power Jets plant at Whetstone became a research plant for the gas turbine division of GEC. GEC then merged its heavy engineering division with Alsthom of France, becoming part of GEC-Alsthom in 1989, which changed its name to Alstom in 1998, when the Lincoln subsidiary was known as EGT (European Gas Turbines).

Siemens

[edit]

In 2003, Alstom sold its gas turbine division (in Lincoln and Franche-Comté) to Siemens.[13] The site of the former headquarters at Thorngate House, on the opposite side of the A15, was redeveloped as residential flats.

Economy of Lincoln

[edit]

When owned by GEC in the late 1960s and early 1970s, many (if not the vast majority) of Lincoln engineering firms did not survive difficult financial conditions. This included Clayton Dewandre, (that made vacuum and air-pressure brake servos and associated equipment for commercial vehicles). WH Dorman had been bought by English Electric in 1961 and took over an old R&H factory on Beevor Street. Dormans would be bought by Perkins in 1993, then closed in 1995.[14]

Only the GEC group of companies in Lincoln (including Dormans) survived the 1970s. The company actually expanded during this difficult time, helped by the fact that 80% of its engines were exported and the North Sea oil industry was rapidly expanding at this time, which required portable electricity generation and heating.

Manufacturing plants

[edit]
Former works off Tritton Road

The original Ruston works (Waterside South, Lincoln) focused on Gas Turbine manufacture from 1967 becoming the head office of Ruston Gas Turbines. Napier Turbochargers, that had been owned by English Electric since 1942, moved to the site from Liverpool.

With the change of ownership in 1989 the name was changed to European Gas Turbines Ltd. Following a spell as Alstom Gas Turbines Ltd, the company is now known as Siemens Industrial Turbomachinery Ltd. The design and research centre in Lincoln opened in May 1957. Siemens announced in September 2009 that Gas Turbine packaging operations were to move abroad with the Lincoln site becoming a feeder plant.

The plant was taken over by William Sinclair Horticulture, who ceased using it in 2015. The building was demolished in 2019.[15]

The Vulcan Foundry in Newton-le-Willows in Merseyside was known as Ruston Diesels (formerly Ruston Paxman Diesels) until 2002. It was taken over by MAN Diesel on 12 June 2000.[16]

Market focus

from Grokipedia
Ruston & Hornsby Ltd. was a major British engineering firm based in , renowned for producing small and medium-sized diesel engines for industrial, agricultural, and marine applications, as well as diesel locomotives. Formed on 11 1918 through the merger of Ruston, & Co. Ltd. of Lincoln (established 1889) and Richard Hornsby & Sons Ltd. of (founded 1828), the company combined expertise in steam engines, , and early internal combustion engines to become a leader in diesel technology. The firm's early innovations included the development of hot-bulb oil engines in the by its predecessors, transitioning to diesel engines in the with models like the IP (introduced around 1915) and AP (1921) series, which powered a wide range of stationary and traction applications. By 1931, Ruston & Hornsby entered production, manufacturing over 5,000 diesel shunting locomotives until 1967, which were widely used in industrial settings such as docks, factories, and quarries across the and beyond. The company also diversified into excavators, cranes, pumps, boilers, and even experimental automobiles and tractors, including the notable Wallis Tractor in the . In the post-war era, Ruston & Hornsby pioneered small gas turbines, with production of the TA model beginning in 1952, and expanded through acquisitions such as Davey, Paxman & Co. in 1940, forming the Ruston-Paxman group focused on advanced engine designs. The company achieved significant export success, supplying equipment for major projects like Australia's power scheme in 1924 with the world's largest at the time. Acquired by English Electric Co. Ltd. in 1966 and later integrated into GEC in 1968, the firm's legacy endured through subsequent mergers into GEC-Alsthom (1989), (1998), and MAN B&W Diesel AG (2000), influencing modern manufacturing.

Background and Formation

Predecessor Companies

Ruston, Proctor and Co. traces its origins to a millwright and engineering firm founded in Lincoln in 1840 by James Toyne Proctor and Theophilus Burton. In 1857, Joseph Ruston, born in 1835, joined the partnership, which was renamed Ruston, Burton and Proctor; following Burton's departure, it became Ruston, Proctor and Co., with Ruston acquiring full control. The company operated from the Sheaf Iron Works in Lincoln, expanding significantly through acquisitions such as a millwright business in 1860 and Whitaker Brothers in 1911. By 1889, it had incorporated as a , focusing on engines introduced in 1860, , and traction engines from 1876. Key innovations at Ruston included early stationary steam engines and the production of the first commercial oil engine in 1894, marking a shift toward internal combustion technology. The firm also manufactured locomotives from 1866, including those for the in 1868, and steam cranes after 1911. Exports grew robustly, with products shipped to markets like and the , and the company earned accolades at Royal Agricultural Shows in 1861, 1877, 1899, and 1900. By 1914, Ruston employed over 5,200 workers, reflecting its status as one of Britain's largest engineering firms. Richard Hornsby & Sons was founded in , , in 1828 by Richard Hornsby (1790–1864) after the retirement of his partner , initially as an ironfoundry producing agricultural implements such as ploughs and seed drills. The firm expanded into engines by 1840, producing its first portable engine in 1849 and earning a prize at the 1851 . In the , it pioneered ploughing equipment, building its first in 1863 under the Bonnall and Astbury patents, and focused on cultivators and threshing machines at its works. The company incorporated as a limited entity in 1879 under Hornsby's sons James and William. Hornsby's innovations included patented ploughing systems, such as double-furrow and reversible ploughs, which enhanced agricultural efficiency, alongside the development of hot-bulb oil engines in collaboration with Herbert Akroyd Stuart starting in 1891—the Hornsby-Akroyd engine, with its first installations in 1892, became a commercial success with over 32,000 units produced. The firm also created the world's first oil-powered in 1896 and an oil that year. Exports were strong, with gold medals at the 1873 Exhibition and the 1900 Exposition, supporting a workforce of 3,500 by 1914.

1918 Merger and Early Operations

Ruston, Proctor and Co. Ltd. of Lincoln merged with Richard Hornsby & Sons Ltd. of on September 11, 1918, to form Ruston and Hornsby Ltd., amid the economic challenges of the post-World War I transition to peacetime markets. Hornsby, a pioneer in heavy oil engines and , faced shrinking demand after wartime production, while Ruston maintained stronger stability through its diverse engineering output, making the amalgamation a strategic move to combine over a century of expertise in internal engines and industrial equipment. The merger established the new entity's headquarters at Ruston's Sheaf Iron Works in Lincoln, with Hornsby's operations integrated to support expanded production, though the Grantham site continued independently for decades. Early leadership drew from both predecessor firms, with successors to the Ruston family—such as long-associated engineers like George Ruston Sharpley—overseeing the transition, emphasizing continuity in management structures to streamline operations. The Lincoln works became the central hub, facilitating the blending of product lines that included steam traction engines from Ruston and oil engines alongside agricultural implements from Hornsby, allowing the company to maintain pre-merger legacies while pursuing joint innovation. In the immediate post-merger years, Ruston and Hornsby issued its first joint catalogs in the early , showcasing integrated offerings of steam and oil-powered machinery for agricultural and industrial use, which supported growing exports to markets in , Asia, and beyond during the interwar economic recovery. A key early step in consolidation came in 1919, when the company acquired the ordinary shares of Ransomes, Sims and Jefferies Ltd., securing a to ensure reliable component supply for its expanding machinery production. This move, alongside the merger's synergies, positioned Ruston and Hornsby as a leading British engineering firm by the mid-.

Core Technologies and Products

Steam Engines and Early Machinery

Following the 1918 merger of Ruston, Proctor and Co. with Richard Hornsby and Sons, Ruston & Hornsby continued to develop and produce a range of -powered machinery, leveraging the established expertise of both predecessors in technology for industrial and agricultural use. The company's engines were primarily designed for stationary power generation in mills and factories, as well as mobile applications on farms and construction sites, reflecting the era's reliance on before the widespread adoption of internal alternatives. Ruston & Hornsby manufactured several types of engines until 1936, including stationary engines for fixed installations, portable engines for temporary power needs, and traction engines in both single-cylinder and configurations. These traction engines, often rated in nominal horsepower (nhp) from 5 to 12, were built with robust frames suitable for pulling heavy loads, drawing on Hornsby's earlier designs from the onward. Boilers for these engines featured horizontal and vertical configurations, with the patented horizontal boiler measuring 7 feet in diameter and operating at 120 psi, while vertical variants ranged from 3 feet in diameter at 120 to 2 feet at 80 psi, providing reliable generation for varied operational demands. In agricultural applications, Ruston & Hornsby produced steam ploughs, threshing machines, binders, and baling presses, which were showcased extensively at events like the 1920 to demonstrate their utility in crop harvesting and soil preparation. The company also adapted Hornsby designs for steam cultivators, building on the 1909 track-laying steam cultivator developed by Richard Hornsby & Sons, which used chain tracks for improved traction in heavy plowing tasks. rollers, including compound and motor-driven variants, were another key output, employed for infrastructure maintenance and featuring similar boiler systems for consistent power delivery. Production of steam machinery peaked in the , with extensive exhibitions and sales highlighting the company's output of traction engines, portables, and agricultural implements, though increasing competition from oil engines posed challenges to sustained viability. Hornsby's pre-merger innovations, such as efficient designs and portable traction systems introduced in the and , contributed to overall improvements in reliability and fuel economy during this period. By the mid-1930s, as market preferences shifted, Ruston & Hornsby ceased production in 1936, marking the end of this foundational era in their portfolio.

Diesel Engines

Following the 1918 merger of Richard Hornsby & Sons and Ruston, Proctor & Co., Ruston & Hornsby rapidly advanced into diesel engine production, leveraging Hornsby's prior expertise in hot-bulb oil engines that predated Rudolf Diesel's compression-ignition patent. From the outset, the company introduced both hot-bulb and true compression-ignition diesels, transitioning from external methods to direct injection systems for improved efficiency. These engines were designed in small to medium sizes, ranging from 10 hp to 1,000 hp, suitable for land-based, marine, and stationary installations, marking a pivotal shift from the technologies of their predecessors. In the 1930s, the Ruston-Hornsby 10H series emerged as a key line of horizontal engines, offering outputs around 10 hp at speeds up to 400 rpm, with applications in light industrial duties such as milling and small pumps. Post-World War II, the company introduced advanced models like the 6VEB, a six-cylinder V-configuration engine delivering 150-225 bhp, and the Alpha series, which extended to higher powers up to 1,000 hp in vertical formats. These engines achieved specific fuel consumption rates around 0.4 lb/bhp-hr, thanks to airless injection and robust construction, enabling reliable operation on heavy fuels. Power outputs varied by model, with examples including 64 bhp at 900 rpm for mid-sized units and 450 hp installations for larger stationary roles. The diesel engines found widespread use in generators for supply, pumps for and , and industrial drives for machinery in factories and farms. By the , export success propelled their adoption in for powering threshers and , and in shipping for auxiliary , with tens of thousands of units sold globally due to their durability and versatility. Innovations included licensing designs to firms like R.A. Lister in for broader production and adaptations for variable speed operations, allowing seamless integration into fluctuating load environments without compromising performance.

Gas Turbines and Advanced Systems

Ruston & Hornsby entered the field of gas turbine development in the post-World War II era, leveraging expertise from diesel engine production to pioneer industrial-scale continuous-flow propulsion systems. The company's gas turbine program began with experimental prototypes in the late 1940s, marking a shift toward high-tech energy solutions for power generation and mechanical drives. These early efforts focused on single-shaft designs suitable for rugged industrial environments, contrasting with the intermittent combustion of piston-based diesels that had defined Ruston & Hornsby's core output. In 1946, Ruston & Hornsby established a dedicated gas turbine department and developed its first prototype, laying the groundwork for commercial production. By , the company demonstrated a gas turbine generator set to the press, showcasing potential for reliable electrical power in remote locations. Full-scale production commenced in with the TA series, when the first unit—a 1,000 kW model—was delivered to an oil company in for compressor drives in the oil fields. This marked Ruston & Hornsby's entry into global export markets, with batch production reaching one unit every two weeks by 1956, half of which were exported. The TA series evolved through the and , incorporating improvements in materials and combustion stability, while production expanded to support applications like an Admiralty trial on a in 1956. The TA series featured single-shaft configurations with a thirteen-stage axial compressor achieving a pressure ratio of 4:1 at full load, supported by sleeve bearings for durability in continuous operation. These turbines operated on versatile fuels such as kerosene or natural gas, delivering thermal efficiencies of approximately 20-25% in industrial settings, which provided a balance of power density and fuel flexibility for the era. Power outputs ranged from around 1,000 kW in early models to up to 10,000 kW in later variants, enabling scalability for diverse loads. By the late 1960s, over 1,000 TA units had been produced, including installations driving alternators for utilities like Snam Progetti in Italy. Building on the TA foundation, Ruston & Hornsby advanced to the TB series in 1970, introducing two-shaft designs for enhanced part-load performance and responsiveness in variable-demand scenarios. The TB range, produced at the Lincoln works, featured ten-stage compressors with pressure ratios up to 14:1, supporting efficiencies approaching 30% in optimized configurations and power outputs from 3 MW to over 5 MW per unit. These turbines found widespread use in gas compression for pipelines, mechanical drives in plants, and power generation, with notable deployments in setups recovering exhaust heat for process steam. Collaborations extended to applications, including auxiliary systems derived from industrial models. By 1986, the overall gas turbine portfolio spanned 1,875 to 66,000 (approximately 1.4 to 49 MW), with 2,300 units installed across 66 countries, predominantly in the oil and gas sector. The evolution continued into industrial and marine adaptations, where TA and TB units powered shipboard generators and pumps, benefiting from their compact footprint and multi-fuel capability. Larger TB models supported integrated energy solutions in refineries. Production under the Ruston name persisted through corporate changes, with the final units assembled before rebranding in the early 2000s, after which Siemens continued manufacturing upgraded versions of the lineage. This progression solidified Ruston & Hornsby's legacy in industrial gas turbines, emphasizing reliability in harsh environments over two decades of innovation.

Wartime Contributions

First World War Involvement

During the First World War, the predecessor companies of Ruston & Hornsby played significant roles in supporting Britain's , particularly through and adaptations to meet military demands. Ruston, Proctor and Company, based in Lincoln, shifted much of its production to wartime needs, supplying steam engines to power munitions factories and providing traction equipment for logistical operations such as transporting supplies and raw materials. The firm also manufactured internal combustion engines for aeroplanes, oil engines for searchlight tractors and ambulances, and steam navvies for extracting raw materials essential to the . Additionally, Richard Hornsby & Sons of contributed through its expertise in tracked machinery; the company's patented chain-track system from 1904, originally for agricultural tractors, influenced early military vehicle designs and was acquired by American firm Holt Manufacturing, which developed it into prototype tanks for the . Ruston, Proctor secured major contracts as a Controlled from July 1915, focusing on munitions production that included 8,000 Lewis guns, 55,000 gun mountings, and 500,000 shells and bombs, alongside engines for 127 British submarines, 30,000 submarine mines, and 2,000 paravanes for mine protection. The company's output surged dramatically, with total wartime production reaching four million items, including 600,000 horseshoes and 28,000 wheels commandeered by the . By , Ruston, Proctor had also become a leading producer of , assembling over 2,750 units such as Sopwith Camels and Royal Aircraft Factory B.E.2s to bolster aerial capabilities. Hornsby's agricultural implements, while not directly repurposed for trench work, supported broader logistical efforts through robust traction systems that aided in overcoming muddy terrains in supply lines. The war profoundly impacted labor dynamics at these firms, driving employment growth and workforce diversification. Ruston, Proctor's workforce expanded from around 5,200 in 1914 to a peak of 7,600 by 1918, incorporating 600 women by 1916 who performed critical tasks such as shell turning, fabric stitching, and assembly work previously reserved for men. The inclusion of Belgian refugees—totaling 57 across various departments—further augmented the labor pool to meet production quotas. These changes reflected the broader national push for industrial mobilization, with women and immigrants filling gaps left by enlisted male workers. Following the in , the abrupt end to wartime contracts left both companies facing economic challenges from scaled-back production. On September 11, 1918—just weeks before the war's close—Ruston, Proctor and Richard Hornsby & Sons merged to form Ruston and Hornsby Ltd., consolidating resources to navigate the postwar transition and repurpose surplus engineering capabilities for civilian markets.
