Riley 9 History
The Vintage Riley Nine was one of the most successful light cars produced by the British motor industry in the inter war period. It was made by the Riley company of Coventry, with a wide range of body styles between 1926 and 1938.
The car was largely designed by two of the Riley brothers, Percy and Stanley. Stanley was responsible for the chassis, suspension and body and the older Percy designed the engine. Why do older brothers get the best jobs?
The 1087 cc four-cylinder engine had hemispherical combustion chambers with the valves inclined at 45 degrees in a crossflow head. To save the expense and complication of overhead camshafts, the valves were operated by two camshafts mounted high in the crankcase through short pushrods and rockers. The engine was mounted in the chassis by a rubber bushed bar that ran through the block with a further mount at the rear of the gearbox.Like all the best cars, drive was to the rear wheels through a torque tube and spiral bevel live rear axle mounted on semi elliptic springs.
At launch in July 1926 two body styles were available, a fabric bodied saloon called the Monaco and a fabric four-seat tourer. The saloon could reach 60 mph. Very quickly a further two bodies were offered, the San Remo, an artillery wheeled basic saloon and a 2-seater plus dickie open tourer and there was also the option of a steel panelling rather than fabric for the four-seater tourer.
After the cars 1926 launch, Mark 1 production actually started in 1927 at Percy's engine factory, due to some resistance in the main works to the new design. It was such a critically acclaimed success that after less than a thousand cars had been produced the works quickly shut down side-valve production and tooled up for the new Nine in early 1928. This switch to the main factory coincided with several modernisations of the Mark 1 - the cone clutch was dropped, the gear lever and handbrake were moved from the right to the centre of the car and a Riley steering box was adopted becoming the Mark II. The Mark III was a gentle update of the II at the end of 1928, evolving stronger wheels and a different arrangement of rods to the rear brakes.
The Mark IV was a thorough re working of the Nine - heavier Riley made 6-stud axles replaced the bought in 5-stud rod brake items and a new cable braking system was introduced with larger drums. The range of bodies was further extended in 1929 with the Biarritz saloon which was a de-luxe version of the Monaco. The improved brakes were fitted using the Riley continuous cable system and if the cable stretched it could be adjusted from the driver's seat.
