Coventry Climax was a British forklift truck, fire pump, racing, and other specialty engine manufacturer. History Pre WW1 The company was started in 1903 as Lee Stroyer, but two years later, following the departure of Stroyer, it was relocated to Paynes Lane, Coventry, and renamed as Coventry-Simplex by H. Pelham Lee, a former Daimler employee, who saw a need for competition in the nascent piston engine market. An early user was GWK, who produced over 1,000 light cars with Coventry-Simplex two-cylinder engines between 1911 and 1915. Just before the First World War, a Coventry-Simplex engine was used by Lionel Martin to power the first Aston Martin car. Ernest Shackleton selected Coventry-Simplex to power the tractors that were to be used in his Imperial Trans-Antarctic Expedition of 1914. Hundreds of Coventry-Simplex engines were manufactured during the First World War to be used in generating sets for searchlights. Post WW1 In 1919, Pelham Lee acquired an existing company, Johnson & Smith Ltd, and changed its name to Coventry Climax Engines Ltd with premises at East Street, Coventry. [Board of Trade Certificate, Herbert Collection, Coventry] (Coventry Simplex continued under separate management). Throughout the 1920s and 1930s, the company supplied engines to many companies manufacturing light cars such as Abbey, AJS, Albatross, Ashton-Evans, Bayliss-Thomas, Clyno, Crossley, Crouch, GWK, Marendaz, Morgan, Triumph, Swift, Standard, and Waverley Cars of London. In the early 1930s, the company also supplied engines for buses, and in 1935 supplied the 'L' engine to David Brown tractors for the 550 Model A, being a collaborative venture with Ferguson. In the 1920s, the company moved to Friars Road, Coventry, and in the late 1930s, they also acquired the former Riley premises on Widdrington Road, Coventry. With the closure of Swift in 1931, the company was left with a stock of engines that were converted to drive electric generators, a field in which they had experience from building WW1 searchlight generators. They also started to make engine driven pumps, and mounted on a trailer as a mobile fire fighting appliance this was to be a great success. The economic problems of the 1930s hit the business hard, and Leonard Pelham Lee, who had taken over from his father, created a separate division of the company for the fire pumps. While the motor car engine business suffered during the recession, the mobile fire pump division of Coventry Climax became a great success, particularly during
