L Gardner and Sons Ltd


L. Gardner and Sons Ltd was a British builder of diesel engines for stationary, marine, road and rail applications. The company was founded in Hulme, Manchester, England in 1868. It started building engines around 1895. The firm ceased engine production in the mid-1990s.

About 1868 Lawrence Gardner set up as a sewing machine maker in Upper Duke Street, Stretford Road, Hulme, Manchester. He died in 1890, but the business was continued by his sons under the name L. Gardner & Sons Ltd.

From about 1895 the company was building gas engines and, in 1899 it moved into Barton Hall Engine Works, Patricroft, Manchester.

In 1903 it became a limited company, L Gardner and Sons Ltd. Norris and Henty Ltd, of London, were appointed as sales agents.

Diesel engine production began in around 1903. In 1912 a new sales subsidiary, Norris, Henty and Gardners Ltd, was formed.

During World War I (1914–1918) the company made munitions and parts for heavy guns and engines for tanks.

During the 1920s there was rapid development in the design of diesel engines. In 1929 a Gardner "4L2" marine engine was fitted into a Lancia bus. This conversion was successful and prompted Gardner to introduce the "LW" series of diesel engines, designed especially for road vehicles but later modified and supplied as a marine engines with factory-fitted bilge pumps.

During the 1930s a number of LW-series engines (usually 4LWs, but occasionally 6LWs) were installed in large luxury cars including Lagondas, Bentleys and Rolls-Royces. The Gardner engine's reliability and economy (tests showed that even a two-ton Bentley could achieve 30 miles per gallon of fuel while having a top speed of 80 mph), coupled to its remarkable refinement and smooth running abilities, made it the only suitable compression-ignition engine at the time

During World War II (1939–1945) Gardner's war work consisted mainly of building diesel engines of their own design. Their 4LK bus engines were also used as the main powerplant in the Royal Navy's X class and XE class midget submarines.
