69-468: The concept of the Mechanical Horse tractor unit with an easily detached articulated trailer was conceived in the early 1930s by Napier & Son . It has one front wheel in the midline. The London and North Eastern Railway had approached Napier for an answer to the problem of replacing horses for local haulage purposes, while retaining the flexibility of changing the wagons and the maneuverability of
138-532: A 40 hp (30 kW), and Edge made a famous 24-hour run in June, covering 1,581 miles (2,544 km) at an average 65.905 mph (106.064 km/h) in a 60-horsepower 589 cubic inch (9,652 cc) (127 × 127 mm, 5 × 5-inch) six, a record which stood for 18 years. The L48, nicknamed Samson , became famous there in the venue's first two years; in 1908, Napier's Frank Newton covered one-half mile (800 m) at 119.34 mph (192.06 km/h) in
207-420: A 990 cubic inches (16.3 L) (165.1 mm × 190.5 mm, 6.50 in × 7.50 in) sidevalve four capable of 103 bhp (77 kW) at 800 rpm, on a wheelbase of 115 inches (2.9 m) with four-speed gearbox and chain drive. Called the "50 hp", only two or three were completed, including one for Rolls. Edge entered one in the 1901 Gordon Bennett Cup , only able to test it en route (it
276-454: A Napier and two Wolseleys. The Napier was a three-speed, shaft-drive 6.44-litre (392.7 cu in) four (127 mm × 127 mm (5.0 in × 5.0 in) of 44.5 hp (33.2 kW) (though described as a 30 hp). Piloted by Edge and his cousin, Cecil, it wore what would become known as British racing green , and won at an average 31.8 mph (51.2 km/h); although by default, since all other entrants retired during
345-492: A S. F. Edge's Napier launch won the inaugural British International Harmsworth Trophy for speedboats at Cork Harbour in Ireland, driven by Dorothy Levitt . She achieved 19.3 mph (31.1 km/h) in a 40-foot (12 m) steel-hulled, speedboat fitted with a 3-blade propeller. As both the owner and entrant of the boat, "S. F. Edge" is engraved on the trophy as the winner. The third crew member, Campbell Muir, may also have taken
414-746: A heater-demister, two rear view mirrors, interior sun-visors, totally enclosed oil-immersed coil spring front suspension and dual rate mounting of semi-elliptic leaf springs at the rear. Later a larger engine was fitted; the Leyland OE160, being an in-house product due to Standard-Triumph and Scammell then being part of the Leyland Group. The OE160 was used in the Leyland Twenty and Leyland 90 commercials built under Leyland badges by Standard-Triumph. The Townsman had better driver controls and faster road speed (50 mph) but still lacked brakes on all wheels; only
483-597: A large rubber bush. A vacuum operated release mechanism replaced the hand lever mechanism used in the Scarab. The futuristic lines of the fibreglass cab were a novelty. Use of GRP (Glass Reinforced Plastic) for the cab had allowed for a more complex shape to be employed. Scammell had experience with GRP cabs in heavy lorries such as the Routeman, Trunker and Handyman which also had cabs designed by Michelotti . The new cab had many new developments, such as vacuum-assisted hydraulic brakes,
552-787: A later model on the Onassis' private island Skorpios . Around 1980, the Fiat 127 -based "Every" appeared, a light buggy-styled vehicle. Michelotti also marketed a luxurious version of the Daihatsu Taft . In 1985 the Michelotti PAC was presented, a one-off citycar prototype (PAC = "Project Automotive Commuter") based on the Daihatsu Cuore . In the 1960s, Michelotti designed a glass-reinforced plastic (GRP) cab for certain lorries made by Scammell , who had become part of Leyland Motors in 1955. The cab
621-647: A limited liability company, D. Napier & Son Limited, although it remained in effect a private company for the next few years. Outside the racing programme, Napier also gained fame in 1904 by being the first car to cross the Canadian Rockies : Mr and Mrs Charles Glidden , sponsors of the Glidden Tours , covered 3,536 miles (5,691 km) from Boston to Vancouver . Recognizing the value of publicity gained from racing , which no other British marque did, in spring, Edge entered an 8 hp (6.0 kW) Napier in
690-836: A number of prototypes which did not go into production, such as the Triumph Fury . The only Triumphs after 1960 that were not his work were the TR6 and the TR7 , plus the Honda -based Acclaim . After Triumph's parent company Leyland Motors became a part of British Leyland , Michelotti undertook a facelift of the BMC 1100 – which became the Spanish-built Austin Victoria and also the South African-built Austin Apache . He also designed
759-465: A stroked (178 mm, 7-inch) L48. The company's last race win was with a four-cylinder at the 1908 Tourist Trophy , using an alias, Hutton, to preserve the reputation of the sixes, in the hands of Willy Watson . At the French Grand Prix , officials showed the perverse reasoning for which they later became notorious by claiming that removable wire wheels were an unfair advantage. When Napier

Napier's 1902 win brought the Gordon Bennett hosting duties to the United Kingdom, and the 1903 event was held south of Dublin , with three shaft-driven Napiers defending the British and Irish honour, all in the (later famous) racing green: two 470 cubic inch (7708 cc) 45 hp (34 kW) fours for Charles Jarrott and J. W. Stocks , with McDonald,
897-411: A wooden cab, the early versions having canvas doors. The Mechanical Horse came in two sizes, capable of pulling loads of three tons and six tons, each of the two sizes had a corresponding coupling size, which became known as the 3-ton and the 6-ton coupling. The tractor units were powered by Scammell's own side valve petrol engine of 1125cc in the 3 ton version and 2043cc in the larger 6 tonner. The engine

While cousins became shipbuilders , he took engineering training in Scotland before coming to London. There in 1808 he founded the firm that was to become D. Napier & Son in Lloyds Court , St Giles, London . He designed a steam-powered printing press , some of which went to Hansard (the printer and publisher of proceedings of
1035-507: Is in possession of the DAF museum in Eindhoven . Michelotti did present a few cars under his own name. The Shellette was a beach car with wicker seats and dashboard in the spirit of Ghia's , Fiat 500 and 600 Jollys. The Shellette was designed in collaboration with yacht designer Philip Schell . Originally constructed with DAF underpinnings, this was later changed to Fiat 850 mechanicals. Unlike
1104-471: The 1896 Paris–Marseille–Paris ), converting from a tiller to a steering wheel and improving the oiling . Dissatisfied, Napier offered to fit an engine of his own design, an 8 hp vertical twin , with electric ignition , superior to the Panhard's hot tube type. Edge was sufficiently impressed to encourage Napier to make his own car and collaborated with Harvey du Cros , his former boss at Dunlop, to form
1173-710: The Dutch firm DAF , starting in 1963 with redesigning the ageing Daffodil 31 model into the Daffodil 32 and DAF 33 . The Shellette beach car was also originally developed to use DAF underpinnings. The DAF 44 (1966) was a completely new design from his hand and he also helped form its derivatives 46 , 55 and 66 , which culminated in the Volvo 66 (1975). In 1968, Michelotti built a concept car based on his DAF 55 design, called Siluro ( Italian for torpedo ), which remained in his possession until his death. The car has since been restored and

Between 1840 and 1860, Napier was prosperous, with a well-outfitted factory and between 200 and 300 workers. Napier made a wide variety of products, including a centrifuge for sugar manufacturing, lathes and drills, ammunition -making equipment for the Royal Arsenal , Woolwich , and railway cranes. David's younger son James Murdoch Napier , born 1823, joined
1311-623: The Leyland National bus and the Australian-made Leyland P76 . Giovanni Michelotti's BMW association started with the BMW 700 (1959) and later the successful BMW New Class series of designs of which the most notable is the BMW 2002. His sport sedan designs later became the BMW design language, that was continued and refined by Ercole Spada well into the 1980s. Michelotti also worked with
1380-601: The Motor Power Company , based in London, which agreed to buy Napier's entire output. The first of an initial order of six, three each two-cylinder 8 hp and four-cylinder 16 hp, all with aluminum bodies by Arthur Mulliner of Northampton and chain drive , was delivered 31 March 1900; Edge paid £ 400 and sold at £500. In 1903 the manufacturing business moved from Lambeth to larger premises in Acton and in 1906 it became
1449-497: The Naiad and Double Naiad was developed for various Royal Navy Fleet Air Arm projects, but did not enter production. The smaller models developed later, the 3,000-hp-class Eland and 1,500-hp-class Gazelle did somewhat better, notably the Gazelle which powered several models of the popular Westland Wessex helicopter. Production ceased when a deal was struck with Rolls-Royce in 1961. At

#17330851699381518-465: The Nomad , a complex "turbo-compound" design that combined a diesel engine with a turbine to recover energy otherwise lost in the exhaust. The advantage of this complex design was fuel economy: it had the best specific fuel consumption of any aircraft engine, even to this day. However, even better fuel economy could be had by flying a normal jet engine at much higher altitudes, while existing designs filled
1587-587: The War Office . Montague Napier's health declined and in 1917 he moved to Cannes, France, but continued to take an active involvement in the company until his death in 1931. Early in the war, Napier was contracted to build engines from other companies' designs: initially the model RAF 3 , a V-12 by Royal Aircraft Factory , and then the V-8 Sunbeam Arab . Both proved to be rather unreliable, and in 1916 Napier decided to design its own instead, an effort that led to
1656-515: The land speed record in Malcolm Campbell 's Napier-Campbell Blue Bird of 1927 and Campbell-Napier-Railton Blue Bird of 1931 and Henry Segrave 's Golden Arrow of 1931 and later in John Cobb 's Napier-Railton and Railton Mobil Special , which held the record from 1939 to 1964. In the 1930s the introduction of much larger and more powerful aero-engines from other companies ended sales of
1725-458: The torpedo boats , minesweepers and other small naval vessels for which it was designed. Also during the Second World War a six-cylinder 300 cubic inch road-vehicle engine was commissioned by the government, but this design was sold to Leyland Motors by 1945. Napier had been taken over by English Electric on 23 November 1942. Last of the great Napier internal combustion engines was
1794-714: The "five-mile world's championship of the sea" and the prize was $ 1,750. In October 1903 Levitt won the Championship of the Seas at Trouville, and the French government bought the boat for £1,000. The 1905 boat Napier II set the world water speed record for a mile at almost 30 knots (56 km/h). In 1912, following a dispute with Edge, the business was restructured. D. Napier & Son Limited went public and bought out Edge's distribution and sales company, S.F. Edge (1907) Limited. The latter soon went into voluntary liquidation and thus
1863-550: The "low end" of the market fairly well. First run in 1949, the Nomad I underwent radical redesign for the Nomad II but was largely ignored by the market and was cancelled in 1955. Along with every major aero engine company in the post-war era, Napier turned to the jet turbine. Seeing a niche not yet adopted up by the larger vendors, Napier developed a number of turboshaft designs which saw some use, notably in helicopters . Its first design,

The GEC operation, now part of Ruston Gas Turbines , later moved to GEC-Alsthom and then Alstom , before being sold to Siemens in March 2003. Napier Turbochargers was bought from Siemens in June 2008 in a management buyout . The buyout
2070-869: The 20th century. His notable contributions were for Ferrari , Lancia , Maserati and Triumph marques. He was also associated with truck designs for Leyland Motors , and with designs for British Leyland (including the Leyland National bus) after the merger of Leyland and BMC . Born in Turin , Italy, Michelotti worked for coachbuilders, including Stabilimenti Farina , Vignale , Allemano , Bertone , Ghia , Ghia-Aigle , Scioneri, Monterosa, Viotti , Fissore and OSI , before opening his own design studio in 1959. He also cooperated with manufacturers producing their own cars based on Fiat or other mechanicals, like Siata , Moretti , Francis Lombardi and Nardi . From 1962, Michelotti concluded cooperation with Carrozzeria Vignale and began his own coachbuilding activities. Towards
2139-405: The 3-ton Scarab. There was no provision for a 6-ton model; more conventional vehicles were used to take on the heavier role. The Townsman closely followed the Scarab in its basic design. The frame was of a welded construction and had integral coupling ramps fitted with Scammell Mechanical Horse automatic coupling. The engine, gearbox and driving axle formed a rigid assembly pivoted at the front end in

The 301.6 cu in (4.942 L) (101.6 mm × 152.4 mm, 4.00 in × 6.00 in) sidevalve suffered problems with its ignition coils and cooling system, and failed to finish. For 1901, Montague designed a car sure not to lack speed, having

It was a bad year for Napier's racing programme; a 35 hp in the hands of Colonel Mark Mayhew in the Paris–Madrid rally lost its steering and hit a tree. Edge, again with McDonald, fared no better with the K5 in
2346-615: The Ghia Jolly, the more powerful 47 hp (35 kW) Shellette was a reasonably useful car having a heater and various other creature comforts. It was also capable of a 60 mph (97 km/h) cruising speed. Only about 80 were built, with around ten still in existence. Famous buyers included the Dutch Royal Family , who used an early DAF-based Shellette at their summer property in Porto Ercole , and Jacqueline Onassis , who employed
2415-466: The L48 at the Blackpool Speed Trials, showing talent by equalling Edge's speed and setting a women's record in the flying kilometre of 90.88 mph (146.26 km/h). By 1907, 1200 people were employed by Napier and were making about a hundred cars a year, aided by continuing racing success. Brooklands opened that year, where Napier engineer H. C. Tryon won the first ever event in
2484-614: The Lion. Napier quickly started work on newer designs, building on experience gained on the X style 16-cylinder, 1,000 horsepower (750 kilowatts) Cub , used in the Blackburn Cubaroo single-engined bomber of the 1920s, and the resulting later 16-cylinder Rapier and 24-cylinder Dagger were both air-cooled H-block designs. Neither the Rapier nor the Dagger proved very reliable, due to poor cooling of

The British armed forces used them in stores and on aircraft carriers. The 6-ton coupling equipment was also fitted to popular makes of lorry such as Bedford, Thornycroft and Austin. Bedford tractor units so equipped were sold under the Bedford-Scammell brand. Such

It was to continue to market the Gazelle, while the completion of existing Gazelle contracts and the Eland remained the financial responsibility of the old company. But it closed only two years later, in 1963. Following the move of the aero engine business, D. Napier & Son continued as a subsidiary of English Electric. With the ending of Deltic sales in

Napier also worked on diesel aircraft engines . In the 1930s it licensed the Junkers Jumo 204 for production in England, which it called the Culverin . It also planned to produce a smaller version of the same basic design as the Cutlass , but work on both
2760-463: The Scammell Scarab. The Scarab retained all the familiar, useful features of its predecessor, with many innovations. The chassis frame was cranked downwards to give a lower centre of gravity. The engine, gear box and rear axle were built as one unit, which aided major maintenance. The whole power unit was fitted low down in the chassis behind the cab. The engine radiator was fitted in the back wall of

Many world speed records on land and water, as well as the Hawker Typhoon and Tempest fighter planes, were powered by Napier engines. During the Second World War the company was taken over by English Electric , and engine manufacture eventually ceased. Today, Napier Turbochargers
2967-504: The business, but failed. James' son Montague , born 1870, inherited the business in 1895, along with his father's engineering talents. Montague was a hobby racing cyclist , and at the Bath Road Club, he met "ebullient Australian" S. F. Edge (then a manager at Dunlop Rubber and colleague of H. J. Lawson in London, and amateur racer of motor tricycles .) Edge persuaded Napier to improve his Panhard "Old Number 8" (which had won
3036-501: The cab, drawing cooling air from a duct behind the right–hand cab door. The larger side-valve petrol engine of 2090cc was used for both the 3 and 6-ton models. Scammell introduced diesel engines to the range, using the Perkins 4.99 for 3-ton and 4.203 for 6-ton models. The rounded all steel cab, fitted with doors as standard, was slightly more comfortable for drivers. The Scarab remained in production until 1967. The Scammell Townsman replaced

She was then commanded to the royal yacht by King Edward VII where he congratulated her on her pluck and skill, and they discussed the performance of the boat and its potential for British government despatch work. Later in August Levitt won the Gaston Menier Cup at Trouville, France. This was described as
3174-558: The end of his life, asked whether he had ever designed anything other than cars, Michelotti acknowledged that virtually all of his design work had involved cars, but he admitted to having designed a coffee making machine shortly after the war . From the late 1950s Michelotti was responsible for all new models produced by the British company Standard Triumph , starting with a facelift of the Standard Vanguard and going on to design other models for Triumph such as: He also created
3243-529: The firm in 1837 and became a partner in 1847, resulting in a change in the private company's name to D. Napier & Son. James succeeded his father as head of the firm in 1867, and after his father's death in 1873, specialized in crafted precision machinery for making coins , and printing stamps and banknotes. James proved an excellent engineer, but a poor businessman, considering salesmanship undignified. His company's fortunes went so bad that there were as few as seven employees in 1895, and James attempted to sell
3312-452: The horse and wagon. These vehicles are often known as "Snub-nose Trucks" or "Snub-nose Lorries" because of the round hood in front of the cab. In 1933 Scammell Lorries Ltd purchased the three wheeled tractor unit design from the Napier Company and promptly turned it into the famous Mechanical Horse. Production of the 3-wheeled Mechanical Horse commenced in 1934. The design had been refined in 1933 by Oliver Danson North , who modified
3381-419: The manufacture and marketing of Napier cars were united under a single organization. Production rose to around 700 cars a year with many supplied to the London taxi trade. That year, only six models were produced. On the outbreak of war sales of private vehicles collapsed and Napier turned to military orders. Vehicle production continued for a time on this basis and 2,000 trucks and ambulances were supplied to
3450-412: The original prototype. This featured automatic trailer coupling (Relatives believe the automatic coupling which remains virtually unchanged today was actually designed by Alistair Moncreiff of Scamell but he received no recognition for his work) the single front wheel could be steered through 360 degrees. This was a very simple and sturdy vehicle which was constructed on a steel channel frame and fitted with

Glidden to create the Glidden Tours in upstate New York , which in turn persuaded Napier to build a factory in Boston. It, along with the Genoa factory (managed by Arthur McDonald ), which built Napiers under licence as San Giorgios from 1906 to 1909,

#17330851699383588-446: The rear axle had brakes. Legislation in the late 1960s regarding braking of goods vehicles meant that the working days of the innovative Scammells were nearing an end. Production ended in 1968. Around 30,000 Mechanical Horses in total were produced over the 35 years of production, but of those only 30 original Mechanical Horses, 60 Scarabs and 30 Townsman models are known to survive.

As Lion sales faded, an attempt was also made to buy the bankrupt Bentley company in 1931 but Napier was outbid at the last minute by Rolls-Royce. The last vehicle project was a three-wheeled tractor-trailer goods vehicle, but rather than produce this itself, the design

Napier continued in ramjet development for several years, typically working alongside the English Electric aircraft design team. In 1961 a new company Napier Aero Engines Limited was formed by D. Napier & Son and Rolls-Royce , to take over
3795-401: The superb W-block 12-cylinder Lion . The Lion came into service shortly before the end of the war. During the First World War the company was also contracted to build 600 aircraft at the Acton factory (50 Royal Aircraft Factory R.E.7 , 400 Royal Aircraft Factory R.E.8 and 150 Sopwith Snipes ). Together with the engine work, this required enormous expansion of the company. By the end of
3864-569: The war, military production had tailed off and the Lion was still barely in use. In 1919 civilian car production was recommenced. The T75 motor car would be Napier's last. Designed by A. J. Rowledge (who left for Rolls-Royce in 1921), its engine was a 40–50 hp 377 cu in (6,178 cc) (101.6 mm × 127 mm or 4.00 in × 5.00 in) alloy six with detachable cylinder head , single overhead camshaft , seven- bearing crankshaft , dual magneto and coil ignition, dual plugs, and Napier- SU Carburettor .

3933-481: Was a British engineering company best known for its luxury motor cars in the Edwardian era and for its aero engines throughout the early to mid-20th century. Napier was founded as a precision engineering company in 1808 and for nearly a century produced machinery for the financial, print, and munitions industries. In the early 20th century it moved for a time into internal combustion engines and road vehicles before turning to aero engines. Its powerful Lion dominated

The car was very expensive, costing about the same as a Rolls-Royce Silver Ghost and in the early 1920s sales were slow. The last car was sold in 1924. The Lion was by now becoming a best-seller for the company, which eventually dropped all the other aero-engines. The Lion went on to be adapted for land and water, to set

Napier developed a marine engine from the Lion aero engine, the petrol-driven Sea Lion, which could deliver 500 hp (370 kW) and was used in the "Whaleback" Air Sea Rescue Launches. During the war (1944) Napier was asked by the Royal Navy to supply a diesel engine for use in its patrol boats , but the Culverin's 720 hp (540 kW)

It was founded in 1919 and ceased manufacture in 1970. The name arose because it was designed to get in and out of narrow twisty passages designed for a horse-and-cart. In the late 1940s, after a production run of 14,000, the Mechanical Horse was superseded by

On 16 October of that year, Napier announced a six-cylinder car for 1904 and became the first manufacturer to make a commercially successful six, a "remarkably smooth and flexible" vehicle 18 hp 301 cu in (4.9-litre) (101.6 mm × 101.6 mm (4.00 in × 4.00 in) with

Napier then designed under the leadership of Ernest Edward Chatterton, Chief Engineer, the Deltic , essentially three Culverins arranged in a large triangle. Considered one of the most complex engine designs of its day, the Deltic was nevertheless very reliable, and was taken into service after the war as a locomotive powerplant (in British Rail 's Class 55 ) in addition to
4554-411: Was offset to the left of the cab, which could cause stability problems in some circumstances. The vehicles had manoeuvrability which was unmatched; it was possible to turn through 360 degrees in under 20 feet with a 16-foot trailer. The road speed of about 20 mph suited the vehicle to local deliveries, and fuel consumption of 10 to 20 mpg was acceptable. Railway companies were the primary customers for
4623-413: Was shortly broken by Bowden's Mercedes , the run was disallowed. The versatile McDonald ran the L48 in the 1905 Gordon Bennett qualifying event at the Isle of Man , taken over for the race by works driver Clifford Earp , who placed ninth. Edge's secretary, Dorothy Levitt , drove a 100 hp (75 kW) development of the K5 at the Blackpool and Brighton Speed Trials in 1905, and the next year ran
4692-527: Was sold to Scammell , which made several thousand. Starting from scratch, Napier decided to use the new sleeve valve design in a much larger H-block 24-cylinder engine, soon to be known as the Sabre . Designed under Frank Halford , the engine was very advanced and proved to be difficult to adapt to assembly line production. Therefore, although the engine was ready by 1940, it was not until 1944 that production versions were considered reliable. At that point efforts were made to improve it, leading eventually to
4761-425: Was the popularity and success of the Mechanical Horse that there was a separate sales department using dealers for this unique machine. During the difficult trading years of the 1930s the threewheeler was the saviour of Scammell Lorries Ltd. From 1937, a version of the Mechanical Horse was made under licence in France, by FAR . The power unit from the successful Citroen Traction Avant was used in this version, which
