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

Origin[edit]

The Gardner engine of X24

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.

Gas and diesel engines[edit]

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.

Automotive engines[edit]

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

Post-war diesels[edit]

After the war the 'LW' diesel engine continued to be built in large numbers for lorries and buses and was later supplemented by the more modern 'LX'. The larger '6L3' and '8L3' engines were used in railway locomotives, such as British Rail Class 01 and British Rail Class 04 and also in vessels of up to 120 feet such as MV Havengore, and the famous maxi yachts Condor and Condor of Bermuda, S.Y. Crescent and others.

Takeover and decline[edit]

In the summer of 1986, after months of denials, Perkins Engines purchased Gardner to complement their line of lighter diesel engines.[1]

L. Gardner and Sons ceased production of new engines in the early 1990s. The introduction of emissions regulations for road-going Gardner diesels would have required the development of significantly modified or totally new engine designs, and in the marine market there was a shift away from big, low-speed, high-torque engines such as Gardners towards adapted high-speed automotive turbodiesels.

Restorers and parts suppliers[edit]

Two spin-off firms from the original company are still in existence: Gardner Marine Diesels[2] overhauls, re-manufactures and installs a wide range of marine-spec Gardners and both they and Walsh Engineering [3] supply genuine Gardner engine parts for all types of Gardner engines worldwide.

Another firm, Marine Power Services.[4] specialise in the restoration and marinisation of Gardners for the inland waterways and the manufacture of component castings incl LW range exhaust, intake and water manifolds. Another firm, Gardner Enthusiast Ltd, manufactures piston rings, engine valves and major engine castings, including marine manifolds for the 8LXB. Gardner Enthusiast Ltd also supply engine castings to Gardner Parts Ltd.[5]
